Embodiment 1
[0037] A post-casting belt drainage structure, including a drainage pipe 1 buried in the post-casting belt, a water collection well 2 connected to the drainage pipe 1, and a diversion part 3 distributed on the side of the post-casting belt. The drainage pipe The pipe wall of 1 is provided with non-uniformly distributed through-holes 11, the pipe body of the drainage pipe 1 is provided with a filter screen 4 for filtering, and the wall of the water collection well 2 is provided with a first connection for connecting the drainage pipe 1. Hole 21, groundwater or water collection first collects around the drainpipe 1 through the diversion part 3, then flows into the drainpipe 1 through the through hole 11 of the drainpipe 1, and then collects into the water collection well 2 to realize the drainage of the basement. The diversion part 3. It is beneficial to lead the water flow into the drainage pipe 1. The filter screen 4 effectively filters the sediment and debris to prevent the th...
Embodiment 2
[0045] A construction method for a post-pouring belt drainage structure, comprising the following steps:
[0046] S1. Concrete porous bricks are built on both sides of the post-pouring belt, and C15 concrete cushion is poured in the middle;
[0047] S2. Open non-uniformly distributed through holes 11 on the PVC pipe wall and cover the filter screen 4 outside the PVC pipe body as the drain pipe 1, and the diameter of the PVC pipe is 50mm;
[0048] S3. Laying the drainage pipe 1 on the upper surface of the C15 concrete cushion;
[0049] S4. lay gravel above the C15 concrete cushion to completely cover the drainage pipe 1;
[0050] S5. After dry laying the linoleum layer above the crushed stone, pour 30mm thick fine stone concrete on the crushed stone;
[0051] S6. Open the first communication hole 21 on the side wall of the water collection well 2 and communicate with the water collection well 2 and the drainpipe 1. In this program, the water collection well 2 can be a cylinde...
