Example Embodiment

[0036] Example 1

[0037] A post-pouring belt drainage structure, comprising a drainage pipe 1 buried in the post-pouring belt 1, a water collecting well 2 connected with the drainage pipe 1, a diversion part 3 distributed on the side of the post-pouring belt, the drainage pipe 1. The pipe wall is provided with non-uniformly distributed through holes 11, the drainage pipe 1 is provided with a filter screen 4 for filtering, and the water collection well 2 is provided with a first communication for communicating with the drainage pipe 1. Hole 21, groundwater or water collection is first collected around the drainage pipe 1 through the diversion part 3, then flows into the drainage pipe 1 through the through hole 11 of the drainage pipe 1, and then collected into the collection well 2 to realize the drainage of the basement, the diversion part 3 Facilitate the introduction of water flow into the drain pipe 1. The filter screen 4 effectively filters sand and debris to prevent blockin...

Example Embodiment

[0044] Example 2

[0045] A construction method of post-pouring belt drainage structure, including the following steps:

[0046] S1. Lay cement porous bricks on both sides of the post-pouring zone, and pour C15 concrete cushion in the middle;

[0047] S2. Open non-uniformly distributed through holes 11 on the wall of the PVC pipe and wrap the filter screen 4 on the outside of the PVC pipe body as the drainage pipe 1. The diameter of the PVC pipe is 50mm;

[0048] S3. Lay the drain pipe 1 on the upper surface of the C15 concrete cushion;

[0049] S4. Lay gravel on the C15 concrete cushion to completely cover the drainage pipe 1;

[0050] S5. After dry laying a linoleum layer on the gravel, pour 30mm thick fine stone concrete on the gravel;

[0051] S6. A first communication hole 21 is opened on the side wall of the collection well 2 and connects the collection well 2 and the drainage pipe 1. In this solution, the collection well 2 can be a cylinder or a rectangular parallelepiped, and the ...

Abstract

The invention discloses a dewatering and drainage structure of a post-cast strip and a construction method thereof. The dewatering and drainage structure of the post-cast strip comprises a drainage pipe embedded in the post-cast strip, a water collecting well communicating with the drainage pipe, and diversion parts distributed on the side part of the post-cast strip, through holes which are not uniformly distributed are formed in the pipe wall of the drainage pipe, a filter screen for filtering is arranged on the outer part of a pipe body of the drainage pipe in a sleeving mode, and a first communicating hole for communicating with the drainage pipe is formed in the well wall of the water collecting well. The construction method of the dewatering and drainage structure of the post-cast strip is further provided, and the problems that dewatering and drainage of a basement is slow, and the drainage pipe is prone to being blocked are solved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a post-cast belt drainage structure and a construction method thereof. Background technique [0002] With the rapid development of urban construction, more and more underground space has been utilized, especially with the increase of high-rise and super high-rise buildings, the application of multi-storey basements is becoming more and more frequent. However, as the depth of the basement deepens, the floor of the basement is more affected by the water pressure in the soil layer. When the floor is closed, the abundant groundwater in the soil layer may form a greater pressure on the local area of ​​the floor, causing the floor to arch and seep. Water leakage, or even overall floating, is extremely detrimental to ensuring the construction quality of the basement, and the role of basement drainage in construction is becoming more and more significant.
