2021 Engineering Project Plan Template III

System Overview:

The piping of this project is concealed within the walls and floor slabs of PVC pipes, and the power supply pipes are galvanized steel pipes.

1, construction sequence

According to the conventional construction method bottom-up with civil construction. Concrete slab, wall, beam, column pipeline with the main construction progress, masonry pipeline with the masonry construction progress, part of the pipeline can not be buried in advance, in the masonry to achieve a certain strength after chiseling buried.

2, construction process

1, concealed pipe laying process: construction preparation → prefabricated processing → pipe, wire box marking → pipe, wire box positioning → pipe connection → pipe, wire box reinforcement.

2, open pipe laying process: construction preparation → prefabricated processing → line marking → pipe connection.

3, construction methods

1, pipe simmering bend: PVC pipe with simmering pipe, steel pipe using stamping elbow welding.

2, pipe cutting: small pipe diameter using hand saws, larger pipe diameter using pipe cutting machine.

3, pipe connection: (PVC pipe): the use of special FST series of fittings, FSJ / Q series of lock nut and special bonding glue.

4, concealed pipe, box fixed: fixed in the board, wooden mold using nails, fine wire to tie the box fixed. The steel mold is fixed with high grade cement mortar. Walls and columns on the line box fixing using tie fixing. Pipes are fixed by wire and steel reinforcement binding, fixed spacing of 1 meter, within 150mm next to the line box for strengthening a binding. Explicit distribution pipe card fixed spacing: pipe card and the middle, the middle of the turn, the distance between the edge of the appliance or wire box for 150 ~ 500mm, the middle of the pipe card spacing according to the "building electrical engineering construction quality acceptance specification" GB50303-2002 Table 14.2.6 settings. Into the light box, switch box, the number of wires more than 4 choose a large box.

5, dark distribution of gas piping: piping should pay attention to the pipe bending radius is not less than 10 times the outside diameter of the pipe. The length of the pipeline without a bend ≥ 30m, a bend ≥ 20m, two bends ≥ 15m, three bends ≥ 8m to add a junction box. Four bends cannot occur in a single section of pipeline arrangement. Buried in the concrete wall or the ground when the pipe laying should be close to the inside of the steel and steel reinforcement binding fixed to minimize the overlap height, pay attention to the pipeline at least 15mm protective layer.

6, open distribution of gas pipeline laying: open distribution of pipes should pay attention to the bending radius should be greater than 6 times the outer diameter of the pipe. Piping arrangement should be smooth, straight.

7, ground connection: power pipe piping pipe and box connection, do across the ground line. Welded steel pipe ground connection using ≥ φ6 round steel span, welding length of not less than 6 times the outer diameter of the steel pipe, double-sided welding.

4, construction quality control focus

1, the focus of the project electrical piping pre-buried bathroom floor concrete slab in the piping pre-buried, because of the project bathroom water pipeline all use the ground within the concealed buried, once there is a board pipeline does not work, the second piping is bound to affect the laying of water pipeline. Therefore, we must ensure that the penetration rate of piping in the board reaches 100%. Construction should pay attention to the firmness of the piping and the quality of the joints, welding connections should pay attention to ensure that the casing length of 2.2 times the diameter of the pipe, the casing diameter should be matched with the diameter of the pipe, counterparts should be set in the middle of the steel pipe. Wire pipe and plastic pipe joints connected and then wrapped with tape.

2, dark distribution of gas piping layout: the plate piping to avoid giving, drainage or other professional risers through the floor position, especially the bathroom floor piping. Piping on concrete walls and columns, in order to ensure the accuracy of the same indoor elevation, use the second takeover, reserve the corresponding groove in the concrete wall, to be completed after the construction of civil engineering and then the work of piping. Pay attention to the protection of the finished products of the ground dumping pipe and the switching dumping pipe of the roof slab to prevent the pipe from being blocked. When piping on the masonry structure, try to piping with the masonry construction at the same time, do not have the same time piping can be in the case of masonry strength up, with a cutting machine slot laying. Pay attention to the width of the groove is not greater than the outer diameter of the pipe 5mm. pipe laying good with higher than the masonry mortar grade cement mortar sealing groove.

3, switches, sockets, light box layout: the location of the light box should pay attention to the center of the room layout, switch box location should pay attention to the distance from the door window edge to consider the decoration of the back door (window) set of the installation size, the location of the socket box should pay attention to whether the impact of the radiators or radiators. The same room in the same category of wire box pre-buried height to be consistent. In concrete walls, columns buried box, pre-buried before you can consider appropriate enlargement of the size of the pre-buried hole to prepare for the installation of the adjustment.

4, electrical piping connection: dark piping with PVC pipe should be careful to ensure that the casing length of 2.2 times the diameter of the pipe, casing diameter should be matched with the pipe diameter.

5, more than one piping side by side into the box, spacing should be uniform, neat and consistent arrangement; tube into the box, box outside should be equipped with lock nut fixed; into the floor-standing distribution box cabinet of the pipeline, the arrangement should be neat, the mouth of the pipe is suitable for higher than the foundation ground 50 ~ 80mm.
