AI Technical Summary
In the existing basement anti-leakage sealing technology, small gaps are likely to appear between the slurry after solidification, reducing the sealing effect and prone to seepage again.
A combined anti-leakage structure is adopted, including cement layer, gravel layer, sealing paste, polyurethane foam filling layer, expanded concrete layer and waterproof coating. The combined structure of these layers is used to enhance the sealing effect of leakage joints.
It significantly improves the sealing effect of leakage joints, avoids the problem of small joints after the slurry solidifies, ensures the long-term waterproofing effect, and avoids re-leakage.

Abstract
Description
Technical Field
[0001] The invention relates to the technical field of construction engineering, and in particular to a basement structure bottom plate leakage blocking structure. Background Art
[0002] A basement is a room whose floor is lower than the outdoor ground level by more than half of the room's net height. Multi-story and high-rise buildings require a deeper foundation. To utilize this height, a basement is built under the bottom floor of the building. This can increase the usable area and save the backfill soil in the center of the house, which is relatively economical. Building a basement below the bottom floor of a house can improve the efficiency of building land. Some high-rise buildings have a very deep burial depth. Taking full advantage of this depth to build a basement has excellent economic and practical effects.
[0003] CN216999882U discloses an anti-leakage plugging device for an extra-long basement. The anti-leakage plugging device discloses that when gaps and water seepage appear in the post-cast zone, slurry for plugging is injected into the grouting cavity through a rubber injection tube. When there is a larger gap, the movable block at the corresponding position can be driven by the pressure of the slurry to move outward, and at the same time the grouting port is opened, and the slurry directly flows into the gap to plug it.
[0004] As mentioned above, in actual use, in basement leakage prevention and plugging, slurry is mostly injected into the gaps to seal the gaps. However, after the existing slurry is sealed, small gaps are easily formed between the slurry and the gaps after the slurry solidifies, which reduces the sealing effect and makes it easy for water seepage to occur again. Utility Model Content
[0005] The present invention discloses a basement structure bottom plate leakage plugging structure, which aims to solve the problem described in the background technology part that "in the basement leakage prevention plugging, slurry is often injected into the gap to plug the gap by the slurry, but after the existing slurry plugging, small gaps are easily formed between the slurry and the gap after solidification, which reduces the plugging effect and makes it easy for water seepage to occur again."
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A basement structure floor leakage blocking structure comprises a block stone cushion layer, a floor layer and a waterproof fine stone concrete layer, wherein the block stone cushion layer is laid under the floor layer, the waterproof fine stone concrete layer is laid on the top of the floor layer, a leakage gap is reserved on the floor layer, and a combined anti-leakage structure is arranged in the leakage gap.
[0008] Preferably, the combined anti-leakage structure includes, from bottom to top, a cement layer, a crushed stone layer, a sealing paste, a polyurethane foam filling layer, an expansive concrete layer, and a waterproof coating. The bottom end of the cement layer is connected to the top end of the block stone cushion layer, and the top end of the waterproof coating is connected to the bottom end of the waterproof fine stone concrete layer.
[0009] Preferably, the bottom of the cement layer is bonded and fixed to the top of the block stone cushion layer; the bottom of the waterproof fine stone concrete layer is bonded and fixed to the top of the waterproof coating layer.
[0010] The beneficial effects of this new type of basement structure bottom plate leakage blocking structure:
[0011] The new type significantly improves the sealing effect of leakage seams by setting up a combined anti-leakage structure, avoiding the problem of small seams easily appearing through slurry sealing and then leaking again. The new type has a novel structure, changes the traditional idea of sealing leakage seams, and has certain promotion value. BRIEF DESCRIPTION OF THE DRAWINGS
