Detailed Description

The present invention will be further described with reference to the following examples and the accompanying drawings.

Example 1

Fig. 1 is a schematic view of a post-cast strip rainwater drainage system according to an embodiment of the invention. The construction process of the post-cast strip rainwater drainage method comprises the following steps: 1) post-cast strip construction; 2) the position of the rainwater drainage port is fixed; 3) building a water retaining reverse ridge; 4) installing a rainwater drainage port and plugging the gap; 5) fixing a drainage tube clamp; 6) installing a basement drainage tube; 7) and mounting a post-cast strip protective cover plate.

The post-cast strip rainwater drainage method comprises the following steps:

a. and a water retaining reverse ridge is built on one side of the post-cast strip.

Fig. 2 is a schematic view of a water retaining reverse ridge rainwater drainage structure according to an embodiment of the invention. The post-cast strip water-retaining reverse ridge is built by 85 bricks, then mortar powder is applied to the post-cast strip water-retaining reverse ridge, a protective cover plate is arranged on the water-retaining reverse ridge, and the rainwater drainage pipe 2 penetrates through a gap between reinforcing steel bars in the post-cast strip and extends to the basement sump 1.

b. And a plurality of rainwater drainage ports are arranged on the side surface of the protective cover plate on the other side of the post-cast strip.

And manufacturing a post-cast strip protective cover plate, wherein the post-cast strip protective cover plate is manufactured by adopting a template with the thickness of 14mm, and the width is determined according to the width of the reserved reverse ridge.

c. Rainwater on the basement top plate 3 flows to the basement sump through the drainage pipe 4. The water flowing pipe 4 is provided with a water flowing pipe bracket 5.

The incoming water on the top plate of the basement flows to the basement sump through the drainage water pipes through the rainwater drainage ports, and then the accumulated water in the basement sump is uniformly discharged. Rainwater drainage mouth sets up the interval and does not exceed 20m, and the end opening is parallel and level with ground, and the later stage rainwater of being convenient for normally flows in, and the upper shed is high with the anti-bank 6 height of manger plate of post-cast strip brick step, the sealing of the protective cover board 10 of the post-cast strip 8 of being convenient for, concrete 9 top. The rainwater drainage port and the basement drainage water pipe are both made of PVC materials, the outer diameter of the rainwater drainage port is a rectangle of 200 x 100, the water outlet is a square of 50 x 50mm, the drainage pipe is a round pipe with the diameter of 75mm, and the rainwater drainage port 7 is connected with the basement drainage pipe in an insertion mode.

The construction notice of the post-cast strip rainwater drainage method of the invention is as follows:

1. the setting requirement of rainwater drainage mouth: the rainwater drainage mouth sets up the interval and should not too big, avoids when rainy season the too big trickling of water yield untimely, and ponding is too much or cause the seepage of other positions of basement roof.

When the reverse ridge is built at the rainwater drainage port, the periphery of the reverse ridge is tightly plugged by mortar, so that rainwater is prevented from leaking from the periphery of the drainage port.

2. The construction requirements of masonry water retaining reverse ridge are as follows: the reverse ridge of manger plate adopts the brick building, should have certain heavy effect, and its function is to block that the extraneous water flows in the post-cast strip, makes the extraneous water flow to basement sump pit through the drainage tube according to keeping good rainwater drainage mouth. The height of the reverse ridge is the same as that of the rainwater drainage port, so that the sealing of the post-stage casting belt protective cover plate is convenient.

3. The quality requirement of the post-cast strip protective cover plate is as follows: the protective cover plate is made of a template and must be firmly fixed and not loosened, and particularly, the rainwater drainage port must be compacted. The protective cover plate has certain bearing performance, and the damage of the cover plate in the later period is avoided.

4. The rainwater drainage mouth meets the requirement with the drainage tube connection: the lower opening of the rainwater drainage opening is a square and is inserted into the round drainage pipe, and the rainwater drainage opening and the round drainage pipe are connected in a socket joint mode. Because the rainwater drainage mouth is fragile, be convenient for the later stage and change.

The method for guiding the rainwater of the post-pouring belt is suitable for the structure of the post-pouring belt in the building engineering, the water retaining reverse ridge is built on the post-pouring belt, the rainwater guiding port is arranged, the external water at the top plate part of the basement flows to the water collecting pit of the basement through the guiding pipe, and then the external water is uniformly discharged, so that the requirements of civilized construction site construction are met, and the development of the construction progress is better promoted.

The post-cast strip rainwater drainage method is applied to tung catalpa home projects in tung cities, has obvious effect and is fully determined by construction units and supervision units.

The above embodiments are provided only for illustrating the present invention and not for limiting the present invention, and those skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Accordingly, all equivalents are intended to fall within the scope of the invention, which is defined in the claims.
