How wide is a winding path

Shaping the "winding paths through the secluded place" mood, the design and layout of the garden road chapters

1. The characteristics of the garden road

The garden road is an integral part of the garden, plays a role in organizing the space, guiding tours, traffic links and provide walking rest places. It is like a vein, the garden of the various scenic spots into a whole. Therefore, in addition to the same traffic function with the sidewalk, there are many unique functions and properties.

2 main types of garden road

2.1 main road.

The main road should be able to run through the various scenic spots in the garden, the main scenic spots and activity facilities, forming the skeleton of the park and back to the loop, so the main road is the widest, generally 4 to 6 m. Structure must be able to adapt to the management of the vehicle carrying requirements. Road structure is generally used asphalt concrete, black gravel and asphalt sand cover, cement concrete paving or precast concrete blocks (500 × 500 × 1000mm) and so on. The main road pattern of the collocation of the whole garden should be as uniform and coordinated as possible.

2.2 Branch roads.

The park is a branch of each sub-scenic area of the internal skeleton, linked to the various attractions, the main road plays an auxiliary role and the nearby scenic areas linked to the width of the road according to the park visitors capacity, flow, function and activity content and other factors. Generally speaking, the width of the single line of the park road for 08 ~ 10m, double line of 12 ~ 18m, triple line of 18 ~ 22m. the natural curvature of the secondary road is greater than the main road, with beautiful stretching rich in elasticity of the curve constitutes a hierarchical landscape.

2.3 Trails.

The path in the garden is the end of the garden system, is the shortcut to the garden landscape, the most artistic part. It is a beautiful curve composition into the landscape, and the surrounding scenery mutual penetration, coincide with the best natural changes. The width of the trail is generally 08 ~ 10m, or even narrower. Materials are mostly simple, rugged, rustic natural stone (schist, stone, pebbles, etc.).

Garden roads should be with the terrain and scenery and the twists and turns, hidden and hidden, "road because of the scenery, the realm because of the depth of the curve", resulting in "the mountains and the water is no way out of the darkness of the flowers and a village," the interest, in order to enrich the landscape, extend the tour routes, increase levels of Scenic depth, active space atmosphere. That is, the zigzagging garden road to have a certain purpose, with the "intention" and curved, curved, such as: in the natural pool bank cloth road with the pool and curved, slightly concave and convex changes; hillside should be circling around and up; between the two mounds along the foot of the mound of the line of bending arrangement; over the rocky hills, flowers and other obstacles to the scenery and curved; in line with the traditional The requirements of the "winding path" and curved. Avoid bending at the same angle, in a short distance too much curved and desperate curved.

Garden road to diversity garden in the form of a variety of roads. In the crowded place or in the courtyard, the road can be transformed into a site; in the woodland or lawn, the road can be transformed into a stepping stone or a rest island; encountered buildings, the road can be transformed into a "gallery"; encountered mountains, the road can be transformed into a mountain road, stirrups, stone steps, caves; encountered the water, the road can be transformed into bridges, embankments, such as TingBu. Road and its rich physical and emotional interest to decorate the garden, so that the garden and because of the road and fascinating.

3 garden road structure design form a variety of typical garden structure is divided into:

3.1 surface.

The top layer of the road. It directly withstand the flow of people, vehicle loads and wind, rain, cold, summer and other climatic effects. Therefore, the requirements of solid, smooth, wear-resistant, with a certain degree of roughness, less dust, easy to sweep.

3.2 Combined layer.

The use of block paving surface layer between the surface layer and the grass-roots level, used to combine, leveling, drainage.

3.3 Subgrade.

Over the roadbed. It on the one hand to bear the load transmitted from the surface layer, on the one hand, the load transmitted to the roadbed. Therefore, to have a certain strength, generally with crushed (gravel) stone, gray soil or a variety of mineral waste, etc. built.

3.4 Roadbed.

The foundation of the pavement.

It provides a smooth base for the garden road, bear the load transmitted from the road surface, and ensure that the road surface has sufficient strength and stability. If the stability of the soil base is poor, measures should be taken to ensure the service life of the pavement. In addition, according to the need to do a good job of road teeth, rain wells, open ditches, steps, concreting, planting ponds and other ancillary engineering design work.

4 paving materials

Pavement paving in our country's classical gardens paving commonly used materials are: stone, square brick, pebbles, slate and masonry fragments. In modern gardens, in addition to the use of traditional materials, cement, asphalt, colored pebbles, cultural stone and other materials are widely used in various forms for garden workers. Traditional pavement pavement by the limitations of the material is mostly gray and a variety of pattern design, such as lotus flower symbolizes "out of the mud but not stained" noble character; orchids symbolize the elegant and secluded, noble character and so on. And in the construction of modern gardens, inherited the ancient paving design of rhythmic beauty of the tradition, and simple, clear, generous style, adding a modern garden of the times.

Currently more popular is the precast block paving. The reason is the lower cost of factory, color varieties, and can be reused. Shape has a square, rectangular, hexagonal, curved and so on. There are many changes, can be put together into a variety of patterns.

Flat ice sheet road is with irregular granite, lapis lazuli plate, etc. carefully staggered pavement surface into. It is characterized by "chaos", avoid rules. In the paving process to avoid connecting into a straight line or parallel to each other, the smaller the gap between the two slabs, the better, the joints can not show too much cement. The texture into a triangle, followed by quadrilateral, pentagonal at least, wood chips trail, with bark and wood broken for covering materials, wood chips criss-crossed, clear texture, with a natural wildlife.

The floor is paved with polished concrete blocks and dark-colored brushed stone or fine striped bricks, and round brushed stone is paved with pebbles.

In addition, the brick pavement can be paved in the shape of zigzag, grain and other shapes; gravel trails, can be paved into the spot, but also with a variety of stripes, grooves in the concrete brick paving, in the sunlight, which can produce good light and shadow effect, not only has good decorative, but also reduces the reflective strength of the pavement to improve the skidding performance of the pavement.

The application of color pavement, has been gradually attached importance to people, so that the pavement paving materials have more selective and rich in flexibility. It can give the "mood" to the landscape. It is generally believed that the warm colors show warm excitement, cold colors are more elegant, bright. Bright colors give people a sense of freshness and happiness, while gray tones show calmness and serenity.

In paving design to consciously use color changes, which can enrich and strengthen the atmosphere of space. The more commonly used color pavement: such as red brick road, brick road, color pebble road, cement toned road, colorful stone road and so on. With the increase of emerging materials, garden pavement will be colorful.

Slope of the garden road slope design requirements first to ensure the stability of the roadbed, try to use the original terrain to reduce the amount of earthwork. But the slope by the road surface materials, road surface cross slope and longitudinal slope can only be changed within a certain range of factors such as the limitations of the maximum longitudinal slope of the general cement road for 7%, asphalt road 6%, brick road 8%. Walking path slope more than 12 ° (20%) in order to facilitate walking, can be set up steps.

Steps should not be used continuously too much, such as the terrain allows, after one or two decades to set up a platform, so that visitors have a respite, the opportunity to watch.

Garden road design in addition to consider the above principles, but also pay attention to the intersection of the connection to avoid conflict, the entrance and exit of the art of handling, and the coordination of the surrounding environment, the surface of the drainage, the impact of the growth of plants and trees and so on. In recent years, the design of some parks and garden paths are not confined to traditional techniques, such as Guangzhou Liuhua Lake Park Spring Garden, due to ornamental needs of the local expansion into a temporary space, around the configuration of plants, rocks, garden benches, vignettes, etc., is very distinctive, it is worthwhile for us to learn.
