Technical Field

[0001] The utility model relates to the technical field of basement anti-seepage, and more specifically, particularly relates to a device for preventing leakage of a post-cast belt of a basement floor. Background Art

[0002] The post-cast joint serves as a temporary construction joint to avoid the adverse effects caused by shrinkage and settlement of the soil structure. However, the location of the post-cast joint on the bottom slab is a weak point in the control of water leakage in the entire basement and is a high-incidence area for leakage.

[0003] At present, water is usually pumped out during pouring of post-casting strips to control water, and then the water is stopped by using the inherent properties of the impermeable concrete. However, it is impossible to completely pump out the water from the entire post-casting strip, and a large amount of water will still combine with the concrete to affect the concrete's impermeability, so that water will still seep out from the post-casting strip.

[0010] Furthermore, a plurality of water-permeable holes are formed on the side wall of the branch pipe, and the side wall of the branch pipe is wrapped with non-woven fabric, and the non-woven fabric covers the water-permeable holes.

[0011] Furthermore, the water retaining plate assembly includes: a plurality of base plates and adjusting rods, the base plate is laid at the bottom of the post-cast strip, the top of the base plate is arranged below the steel bar layer, the adjusting rod is slidably connected to the top of the base plate, and the adjusting rod passes through the steel bar layer.

[0028] A rubber sleeve 321 is bonded to the top of the top pipe 32. The rubber sleeve 321 is conical. The top area of ​​the rubber sleeve 321 is smaller than the bottom area of ​​the rubber sleeve 321. The top of the rubber sleeve 321 is hollow. A water pump pipe can be inserted into the top of the rubber sleeve 321. The water pump pipe can extend into the bottom pipe 31 through the top pipe 32. The rubber sleeve 321 wraps around the water pump pipe to make the top pipe 32 and the bottom pipe 31 airtight, which is convenient for pumping water.

[0029] A connecting groove 311 is formed on the side wall of the bottom tube 31 .

[0030] like Figure 2 As shown, the water collecting pipe 2 includes a main pipe 21 and three branch pipes 22. The main pipe 21 and the branch pipes 22 are all PVC pipes. The branch pipes 22 are horizontally arranged along the short side of the post-cast strip. The front end of the branch pipe 22 intersects with the main pipe 21. The main pipe 21 is connected to the bottom pipe 31. When pumping water, the branch pipe 22 absorbs water in the post-cast strip and then the water enters the main pipe 21, and then the water enters the bottom pipe 31.

[0031] The side wall of the branch pipe 22 is provided with a plurality of water holes 221, through which water seeping from the post-cast strip enters the branch pipe 22. The side wall of the branch pipe 22 is wrapped with non-woven fabric, which covers the water holes 221. The non-woven fabric protects the water holes 221 to prevent mud, sand and dust from entering the water holes 221 and blocking them.

[0032] like Figure 4 As shown, the water retaining plate assembly 4 includes: a plurality of bottom plates 41 and an adjusting rod 42, the bottom plate 41 is placed vertically, the bottom plate 41 is laid at the bottom of the post-cast strip, the bottom plate 41 is installed before the steel layer 1 is tied, the top of the bottom plate 41 is arranged below the steel layer 1, the shape of the bottom plates 41 close to both sides of the post-cast strip is in contact with the side wall of the post-cast strip, and the shape of the other bottom plates 41 is a rectangular block as a whole, the bottom plate 41 can pass through the hole in the steel layer 1, the adjusting rod 42 is slidably connected to the top of the bottom plate 41, and the adjusting rod 42 passes through the steel layer 1.

[0033] A protrusion 411 is provided on one side wall of the bottom plate 41, and a groove 412 is provided on the other side wall of the bottom plate 41. The protrusion 411 of the bottom plate 41 close to the connecting groove 311 is slidably connected to the connecting groove 311, and the protrusion 411 of the bottom plate 41 far from the connecting groove 311 is slidably connected to the groove 412 of the adjacent bottom plate 41. During installation, the bottom plate 41 is inserted into the connecting groove 311 or the groove 412, and a corresponding number of bottom plates 41 are connected according to the width of the post-cast strip. After the bottom plate 41 is installed, mortar is applied to the bottom of the bottom plate 41 for positioning. The mortar has low strength and is easy to remove when the bottom plate 41 is disassembled. The bottom plate 41 and the bottom pipe 31 are connected as a whole to separate the post-cast strip. When water seeps before the post-cast strip is poured, it can be judged which area has a leakage point according to the water outlet height of different dividing strips. Before pouring the post-cast strip, the area with serious leakage can be checked. If the leakage point can be found, the leakage point is sealed with waterproof material in advance.

[0034] A slideway 413 is provided on the top of the bottom plate 41, and a slider 421 is provided at the bottom of the adjusting rod 42. The slider 421 is slidably connected to the slideway 413, so that the position of the adjusting rod 42 can be adjusted. When tying the steel bar layer 1, if the adjusting rod 42 conflicts with the position of the steel bar, the adjusting rod 42 can be slid to avoid conflict with the steel bar.

The rectangular holes are distributed on both sides of the circular hole. The top pipe 32 passes through the circular hole, and the adjusting rod 42 passes through the rectangular hole. The circular hole is used to fix the position of the top pipe 32, and the rectangular hole is used to fix the position of the adjusting rod 42, further fixing the position of the bottom plate 41 to prevent the bottom plate 41 from tilting.

[0036] The use principle of this embodiment:

[0037] Before pouring the post-casting strip, extend the pump into the bottom pipe 31 to pump out the water in the post-casting strip to avoid the water and concrete from combining to weaken the concrete strength and affect the combination between cement and stone, and reduce the probability of crack seepage. Then pour concrete into the post-casting strip, and the water left at the bottom of the post-casting strip is impacted to the top by the concrete. When the water is higher than the steel layer 1, the water can be pushed into the adjacent post-casting strip by tools such as scrapers. Then, the adjacent post-casting strip is pumped by pumping to ensure that the concrete of the post-casting strip currently poured has less water, strong impermeability after the concrete solidifies, and is tightly combined with the surrounding concrete, so that water is not easy to penetrate upward. Then, the adjacent post-casting strip is poured in the same way. After the pouring is completed, the positioning plate 5 is taken out, the top pipe 32 is rotated out and separated from the bottom pipe 31, and then the adjusting rod 42 is pulled up and the bottom plate 41 is raised for recovery, thereby combining the concrete of the two sections of the post-casting strip. The concrete poured in sections can reduce the water content in the post-casting strip, give full play to the concrete's own impermeability, and reduce groundwater leakage.

[0038] After the concrete solidifies, the waterproof roll 6 is laid again on this part of the concrete, and the waterproof roll 6 covers the joint part of the concrete to further prevent water seepage in the post-casting zone.
