Description

Technical Field

[0001] The utility model specifically relates to a drainage structure for a basement post-cast zone, belonging to the technical field of building construction. Background Art

[0002] The drainage structure of a basement's post-cast zone is crucial for ensuring structural stability and preventing water leakage. This complex system requires comprehensive consideration of multiple aspects, including base preparation, casing installation, infill sealing, water pumping, and waterproofing measures. During construction, strict adherence to specifications is crucial to ensure the stability and waterproofing of the drainage structure.

[0003] For example, a Chinese patent document with the announcement number CN222140092U discloses a drainage structure for a post-cast zone in a basement, comprising a bottom concrete layer, a waterproof structural layer provided on top of the bottom concrete layer, a waterproof membrane laid on top of the waterproof structural layer, and a top concrete layer provided above the waterproof membrane; the top of the waterproof structural layer is provided with inclined surfaces inclined inward from both sides, and a water trough is provided between the two inclined surfaces; the water trough is provided with a drainage trough, and both ends of the drainage trough are connected to the outside world; the top of the drainage trough is covered with a support cover, and the support cover is composed of a dense porous steel plate mesh. Water that seeps down is guided into the drainage trough by the inclined surfaces and then discharged through the drainage trough. The support cover is provided on the drainage trough to provide support and isolation, thereby preventing concrete from entering the drainage trough when the top concrete layer is poured, causing poor drainage and affecting the waterproof effect.

[0004] However, when in use, the diversion effect for water seepage is low, and when in use, the connection effect between the post-pouring strip and the base layer is poor, and the waterproof structure layer is easily separated, which affects the service life. Utility Model Content

[0005] The purpose of the utility model is to address the deficiencies of the existing technology and provide a basement post-cast zone drainage structure to improve the connection effect between the post-cast zone and the foundation bottom plate and facilitate drainage.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions: a basement post-cast strip drainage structure, including a base layer, both sides of the upper end of the base layer are cast with foundation bottom plates, and one side of the upper end of the foundation bottom plate is cast to form a bulge, which reduces the exposed area of ​​the post-cast strip after casting and improves the connection effect after casting, a post-cast strip casting area is formed between the foundation bottom plates, and a post-cast strip is cast inside the post-cast strip casting area, a water-stop steel plate is pre-buried in the middle position of the opposite side of the foundation bottom plate, and a water pipe is fixedly installed on the lower end of the water-stop steel plate in an array, and the upper end of the water pipe is connected to the upper surface of the water-stop steel plate, The upper surface of the layer is located in the middle position of the casting area of ​​the post-cast strip, and an arc-shaped water guide trough is fixedly installed. One end of the water guide pipe extends to the upper end of the water guide trough. During construction, the water guide trough is made of corrosion-resistant polytetrafluoroethylene plastic, and the surface of the water-stop steel plate is coated with a corrosion-resistant agent. When casting the post-cast strip, the tensioning effect of the water-stop steel plate enables the post-cast strip to be stably connected to the foundation bottom plate to avoid the shelling problem. When drainage is required, the water guide pipe drains the accumulated water at the water-stop steel plate position to the inside of the water guide trough, and the accumulated water is discharged through the water guide trough.

[0007] Preferably, a lower waterproof belt is laid at the lower end of the base layer and the foundation slab, and an upper waterproof belt is laid at the upper end of the waterstop steel plate on one side of the foundation slab. The lower waterproof belt and the upper waterproof belt are both connected to the waterstop steel plate. The lower waterproof belt and the upper waterproof belt improve the waterproof performance of the base layer and the foundation slab, and avoid seepage.

[0008] Preferably, the interior of the water channel is paved with a gravel layer, and the upper end of the water channel is paved with a mesh made of canvas. The gravel layer and the mesh can avoid blockage during drainage, and the mesh can improve the protection effect of the gravel layer when pouring the post-casting strip, so that the gravel layer remains fluffy.

[0009] Preferably, one side of the waterstop steel plate is evenly fixed with embedded reinforcement, and the embedded reinforcement extends to the inside of the foundation slab. The embedded reinforcement improves the stability between the waterstop steel plate and the foundation slab when embedded.

[0010] Preferably, a steel mesh is laid on the upper surface of the waterstop steel plate, and the steel mesh covers the upper end of the water pipe. The steel mesh reduces the risk of pouring materials entering the interior of the water pipe and clogging the water pipe when pouring the post-cast strip.

[0011] Preferably, a tensioning member is embedded inside the protrusion, and the tensioning member is in an inclined state, and a guide steel plate is fixedly installed between the tensioning members. The tensioning member not only facilitates the installation of the guide steel plate, but also further improves the connection effect between the foundation base plate and the post-cast strip.

[0012] Preferably, the guide steel plate is an inverted structure, and both ends of the guide steel plate extend to the upper end of the waterstop steel plate. The waterstop steel plate is an L-shaped structure. Through the guide steel plate, it is convenient to make the accumulated water gather to the position of the waterstop steel plate during drainage, so as to facilitate drainage through the water guide pipe and the water guide trough.

[0013] Preferably, one end of the tensioning member is a T-shaped structure, and the end of the tensioning member in the T-shaped structure is located inside the protrusion, thereby improving the connection stability between the tensioning member and the protrusion when the tensioning member is embedded.

[0014] The beneficial effects of the present invention are: by adopting pre-buried water-stop steel plates and tensioning parts, the connection stability between the foundation base plate and the post-cast strip is improved after the post-cast strip is cast, and drainage is facilitated by the guide steel plates, water-stop steel plates, water pipes and water guide grooves, and the gravel layer is used to avoid blockage of the drainage position during casting, thereby improving the stability of drainage in the later stage.
