Construction technology of garden paving and garden path?

What is the specific content of the construction technology of garden paving and garden road, the following Zhongda consulting for you to answer.

According to the garden paving and garden pavement layer of paving materials, can be divided into concrete garden road, granite garden road, broken collocation of granite garden road, cement surface brick garden road, small brick garden road, cobblestone garden road, etc. Some of the garden road by a variety of different materials mixed paving, composed of colorful patterns, this garden road paving technology requirements are high, and the construction of the difficulty is also greater.

1 granite garden paving methods and construction points

Garden paving, should be selected according to the requirements of the construction drawings of granite dimensions, a small number of irregular granite should be cut and processed on site. First of all, there will be missing edges and corners, cracks and local pollution discoloration of granite selection out, intact set of square check, specifications, such as size deviation, should be corrected by grinding edge. Some of the surface of the garden road to be paved into a pattern pattern, pick out the granite should be classified according to different colors, different sizes, different long flat shape stacking, paving patchwork to facilitate the use.

For curves, arcs and other shapes of the garden path, its granite according to the plane arc processing, granite according to different sizes stacked neatly. The granite of different colors and different shapes are numbered to facilitate the construction without mess.

Before the granite block stone paving, should be first pop-up line, pop-up line should be paved a number of dry line as the baseline, play the role of the standard tendon, and then paved to both sides to open up, granite should also be splashed with water to wet before paving, shade dry for use. When paving, in the leveling layer evenly spread a layer of cement mortar, brush with the paving, with 20mm thick 1:3 dry cement mortar for bonding layer, granite placement, with a rubber mallet, both to achieve the height of the paving, but also to make the mortar bonding layer is smooth and dense. For granite for trial spelling, check the color, number, spelling is in line with the requirements, whether the pattern is beautiful. For the higher requirements of the project should first do the same plate section, invite the construction unit and supervision engineers for acceptance, meet the requirements before the construction of large areas. The same piece of ground plane has a height difference, such as steps, water features, tree pools and other intersections, before paving, granite should be cut and processed, arc curve should be polished to ensure that the pattern pattern standard, fine, beautiful. Granite paving after the use of colored cement mortar in the hardening process of the water required to ensure that the granite and mortar bonded firmly. Prohibit treading within 3 days of the maintenance period. Granite surface layer of the surface should be clean, flat, axe chiseled surface pattern clear, neat, color and lustre consistent, paving surface flat, axe chiseled surface pattern cross, neat and beautiful, joints uniform, perimeter straight, inlaid correctly, no cracks in the slab, drop corner and other defects.

2 cement surface brick garden road paving method

Cement surface brick is a high-quality color cement, sand, through the mechanical mixing and molding, full maintenance and become, its high strength, wear-resistant, bright colors, varieties. Cement tile surface can also be made into convex and round convex pattern and other shapes. Cement brick garden paving and granite garden paving method is more or less the same. Cement brick because it is a mechanism brick, color varieties than granite, so before paving should be in accordance with the color and pattern classification, there are cracks, corners, surface defects in the face of the brick, should be eliminated.

Specific operational steps are as follows:

(1) grass-roots level cleanup: in the cleaned up the ground, find the rules and flooding, sweeping the cement slurry, and then according to the ground elevation to leave out the thickness of the cement face brick to do the ash cake, with 1:3 dry mortar punching, scraping, the thickness of about 20mm, scraping the usual mortar to shoot solid, scraping and watering maintenance.

(2) pop-up line pre-paving: in the leveling layer pop-up positioning cross line, according to the design pattern of pre-paving brick, brick seam top reserved 2mm, according to the position of pre-paving ink line pop-up cement brick four sides of the border, and then in the border line on the line to draw the demarcation point of each row of bricks.

(3) soaking wet: before paving, should be soaked in water for 2~3 hours, and then take out the shade dry after use.

(4) cement face brick paving work, should be completed before the mortar set. When paving, the brick is required to be flat and set correctly. Before continuing to pave after the construction break, the cement mixed mortar should be removed from the extruded brick that has been paved.

(5) paving masonry, ground bonding layer of cement mixed mortar, patting and rubbing flat. Cement brick back to be clean, first brush out a layer of cement lime mortar, brush with paving, in place with a small mallet chisel. Pay attention to control the thickness of the bonding layer mortar, minimize knocking. In the process of paving construction, such as the appearance of non-integral bricks cut with a stone cutting machine.

(6) cement face brick in paving 1~2 days, with 1:1 thin cement mortar caulking. Surface layer on the overflow of cement mortar to be removed before setting, with gaps in the cement mortar set, and then clean the surface layer. Finish 24 children watering maintenance, completion of 3 ~ 4 days shall not be stepped on.

3 small green brick garden paving method

Small green brick cloud road paving before, should be selected according to the requirements of the design drawings of small green brick size, specifications. First of all, there will be missing edges, falling corners, cracks and local pollution discoloration of small green bricks picked out, intact set of square check, specification size deviation, should be grinding edge repair certificate. In the small green brick paving before, should be first line, and then according to the requirements of the design drawings first paved sample section, especially paved into the mat pattern, herringbone pattern, oblique willow leaf, cross-stitch, gossip brocade and other various, tortoise back brocade and other various forms of surface layer of the garden path, should be paved a section in advance, to see if the form of the surface layer meets the requirements, and then paved over a large area.

Operating steps:

(1) grass-roots level, bedding; grass-roots level practice is generally tamped plain soil → crushed stone bedding → plain concrete bedding → mortar bonding layer.

In the bedding construction, should do a good job of elevation control, gravel and plain concrete bedding thickness should be done according to the requirements of the construction drawings, gravel bedding is generally thinner.

(2) pop-up line pre-paving: in Su concrete matting pop-up positioning cross center line, according to the construction drawings marked surface layer form pre-paving a section, meet the requirements, and then large-scale paving.

(3) first to do the garden road on both sides of the "ZiYa brick", equivalent to modern road side stone, so to be paved first, with cement mortar as a bedding stone, and reinforcement.

(4) small green bricks and small green bricks should be squeezed between the compact, paving is completed, with fine gray sweeping.

4 cobblestone garden road paving method

Cobblestone is 10~40mm shape round smooth river scour stone. The garden path paved with cobblestone looks stable and practical, and has the style of Jiangnan garden. This kind of garden path is also often used as people's fitness path. Completely paved with cobblestone garden paths tend to be slightly monotonous, if the cobblestones in the cobblestones between the addition of a few natural flat cut stone, or a small number of color cobblestones, it will be much more outstanding. Paving cobblestone road, pay attention to the shape of the pebbles, size, color is harmonious. Especially when configured with cut stone slabs, the pattern formed by interlocking to be natural, cut stone and pebble stone quality and color it is best to avoid exactly the same, in order to show the beauty of the road changes.

Construction, because the size of the pebbles, the height is completely different, in order to make the pavement flat, must work on the roadbed. First fill the undried mortar, and then fill the pebbles and cut stone one by one, pebbles are egg-shaped, you should choose the smooth and rounded side up, in the use as a courtyard or garden road is generally buried horizontally into the mortar, in the use as a fitness trail is generally buried vertically into the mortar, the amount of buried pebbles is about 2/3, so that the more solid. The larger part of the buried mortar more to make the road surface neat, consistent height. Do not put the thinnest side of the pebbles flat in the mortar, will be very easy to fall off. After the arrangement of pebbles, and then between the pebbles filled with thin mortar, fill solid even after the completion. The lines between the pebbles should be irregularly shaped, not cross-shaped or straight lines. In addition, the density of pebbles should be balanced, not partially crowded, partially loose. If you want to make a pattern should be first platting and then laying.

The cobblestone ground paving should be completed immediately with a wet rag gently wipe the surface of the mortar, so that the cobblestone to keep clean, and pay attention to the construction site of the finished product protection.

The cobblestone garden road roadbed practice is also generally compacted soil → gravel bedding → plain concrete bedding → mortar bonding layer → pebble surface layer. This grass-roots level practice and general garden road grass-roots level practice is the same, but because the surface is cobblestone, adhesion and integrity is poor, so if the grass-roots level is not stable enough pebble surface layer is likely to loose spalling or cracking, so the whole cobblestone garden road construction grass-roots level construction is also a very critical step.

5 color concrete molded garden road paving method

Color concrete molded garden road is a kind of surface layer for the concrete ground using cement wear-resistant materials paved, it is a silicate cement or ordinary silicate cement, wear-resistant aggregate as the base material, add the appropriate amount of additives composed of dry mix materials. The specific process is as follows: ground treatment → laying concrete → vibration compaction smoothing concrete surface → covering the first layer of color reinforced powder → compaction smoothing color surface → sprinkle mold releasing powder → compression molding → maintenance → water washing construction surface → drying and maintenance → on the sealant → delivery and use.

Grass-roots level practice with the general practice of the grass-roots level of the garden road, the key is the color concrete molded garden road surface layer practice, it is good or bad, directly affecting the final quality of the garden road. Initial colored concrete is generally used on-site mixing, on-site pouring method, flat plate vibrating machine for vibration, direct leveling, wooden crab playing light. Before the concrete is about to finalize, with special molds to press out the pattern. Currently also can use commercial concrete floor with cement-based wear-resistant materials. Color concrete should be a batching, a pouring, to avoid multiple batching and color difference. Color concrete molded garden road pattern is based on the mold and molding, so the mold should be customized according to the requirements of the construction drawings, or to the relevant professional units to purchase suitable molds.

6 wood paving garden path paving method

wood paving garden path stone using wood paving garden path. In the garden project, wood paving garden road is an outdoor sidewalk, the surface layer of wood is generally used wear-resistant, corrosion-resistant, clear texture, high strength, not easy to crack, not easy to deformation of high quality wood.

General wood paving garden road practice is: plain soil compacted → gravel bedding → plain concrete bedding → brick piers → wooden grill → surface layer of wood. From this order can be seen, wood paving garden road and general block stone garden road grass-roots level practice is basically the same, the difference is the addition of brick piers and wooden grill.

The moisture content of the wood for the planks and grates should be less than 12%. Timber in the pavement should also be done before fire, corrosion, moth and other treatments

(1) brick piers

Generally use standard brick, cement mortar masonry, masonry height should be determined according to the height of Mu paving overhead and conditions of use. Brick pier and brick pier distance between the general should not be greater than 2m, otherwise it will cause the end of the wood grille increased size. Brick pier arrangement is generally consistent with the arrangement of wood grille, such as wood grille spacing of 50cm, then the spacing of the brick pier should also be 50cm, brick pier elevation should meet the design requirements, if necessary, can be smeared on the top surface of cement mortar or fine stone concrete leveling.

(2) wood grill

The role of wood grill is mainly to fix and support the surface. If analyzed from the state of force, it can be said to be a small beam.Uoyi, wood grill section selection, should be based on the size of the spacing of the brick piers and make a difference. The spacing is large, the span of the wood joist is large, and the section size should be larger accordingly. Wooden grill paving, should be leveled. Wooden grill installation should be firm, and keep straight in the wooden grill between the good to set up scissor braces, set up scissor braces is mainly to increase the lateral stability of the wooden grill, a single piece of individual grill into a single piece of wood paving garden road to increase the rigidity of the wooden paving. In addition, the setting of scissor braces, for wood joist this warping deformation also plays a certain role in restraining. Therefore, in the overhead wood grass-roots level, grill and grill between the scissors brace, is to ensure the quality of the construction measures. Scissors braces arranged on both sides of the wood grille, with nails fixed to the wood grille, spacing should be arranged according to design requirements.

(3) the surface of the plank laying

The surface of the plank laying is mainly used nail fixing, i.e., with nails will be the surface of the slats fixed on the wooden grille. The splicing of the slats is generally flat and staggered. The laying direction of the wooden slats is generally perpendicular to the direction of people's walking, but also can follow the direction of people's walking, which should be laid in accordance with the requirements of the construction drawings. Nails into the planks before, can also follow the direction of people walking, which should be laid in accordance with the requirements of the construction drawings. Nails into the board before the nail cap should be smashed flat, and then in the nail into the board. Use tools to poke the nail cap of the iron nail into the plank 3~5mm.Wood paving garden road planks paved, the application of portable planer will be the surface planing, and then by the master painters for sand, embedded, batch, brush and other paint coating work.

7 grass brick paving

Grass brick paving stone in the turn of the holes or between the cracks of the brick planting grass a kind of paving. If the grass is lush, this paving looks like a grassy field and is flat and hard. Some of them are used as parking lot surfaces.

The grass brick paving grass-roots practice is compacted soil → gravel bedding → plain concrete bedding → fine sand layer → bricks and planting soil, grass seed.

There are also some grass-planting brick paving grass-roots level practice is: compacted soil → gravel bedding → fine sand layer → bricks and planting soil, grass seed.

From the grass-roots practice of planting grass brick paving can also be seen, soil compaction, gravel bedding, concrete bedding, and general granite road grass-roots level practice is the same, the difference is that in the planting of grass brick paving, there is a layer of fine sand, there is a different surface material. Therefore, the key to the practice of grass brick paving also lies in the surface layer of grass brick paving. Should be selected according to the requirements of the design drawings of grass tiles, currently commonly used grass tiles have cement products of two-hole bricks, there are no holes in the cement of small square bricks. Grass-planting brick paving, brick and brick spacing, generally about 50mm, this interplay, sprinkle planting soil, in the dial into the grass seed, at present there is also a grass-planting brick grille, is a kind of a certain strength of plastic made of grille, the finished product is a 500mm × 500mm piece of grille, will be laid directly on the ground, in the sprinkling of planting soil, planting grass, after the grass, it became a grass-planting brick paving.

8 Permeable Brick Pavers

With the development of the cause of gardening and landscaping, there are many new materials used in gardening and park buildings, permeable brick pavers is a novel brick. Functions and characteristics of permeable bricks:

(1) All raw materials for a variety of waste ceramics, quartz sand and so on. Square brick waste and secondary products used to make permeable brick fabric, the base material is mostly ceramic waste and secondary products.

(2) Permeable bricks have very strong water permeability and water retention, and the rate of water permeability can reach more than 5mm/s, and its water retention can reach more than 12L/m2. Due to its good water permeability, water retention, when it rains, rainwater will automatically penetrate under the brick until the surface, part of the water retained inside the brick. The rainwater will not flow around like on the concrete pavement, and finally flow into the river completely through the underground waterway. When the sky is clear, the water that penetrates under the brick or remains inside the brick will evaporate into the atmosphere, and play a role in regulating air humidity, lowering the atmospheric temperature, and removing the city's "heat island" effect.

The excellent water permeability and water retention comes from the product's porosity of about 20%. The strength of the product can meet the form of load for more than 10t car. Overseas, such as Japan, etc., city sidewalks, pedestrian streets, apartment parking lots, etc., can be paved like granite during construction.

The grass-roots level of permeable brick practice is: plain soil compacted → gravel bedding → gravel sand bedding → anti-seepage geotextile → 1:3 dry mix yellow sand → permeable brick surface layer.

From the permeable brick grass-roots level practice can be seen in the grass-roots level increased a reverse osmosis geotextile, so that the permeable brick water permeability, water retention performance can be fully played to show.

The laying method of geotextile can refer to the requirements of the product manual

The paving method of permeable brick is the same as the paving method of granite block, because of the dry sand underneath, so it is more convenient to pave than granite.
