AI Technical Summary
Existing technologies fail to effectively integrate basement walls, floor slabs, and anti-buoyancy and anti-uplift structures in basement construction, leading to groundwater leakage problems. Furthermore, the anti-buoyancy structures increase construction costs and have low utilization rates.
An integrated connection structure is used to connect the basement side walls, floor slab, tension piles and support piles, combined with a drainage structure to drain accumulated water and prevent leakage. This includes an integrated connection seat, a water collection ditch, a hollow drainage cavity in the tension piles and a backflow prevention component.
It improves the stability and buoyancy resistance of the basement structure, prevents leakage, reduces construction costs, and enhances the overall integrity and stability of the basement.

Abstract
Claims
1. A basement side wall anti-floating and anti-seepage structure, characterized in that: The system includes side walls, a base slab, retaining piles, tension piles, and multiple integrated connection structures. The side walls, base slab, retaining piles, and tension piles are connected as a whole through the integrated connection structures. Each integrated connection structure includes an integrated connection seat and a water collection ditch. The water collection ditch is installed below the integrated connection seat. The top of each tension pile is fixedly installed at the lower end of the integrated connection seat. The tension pile passes through the water collection ditch and its lower end is inserted into the soil. The inner cavity of each tension pile is a hollow drainage cavity. The water collection ditch and the hollow drainage cavity of the tension pile are connected through seepage holes.
2. The basement side wall anti-floating and anti-seepage structure according to claim 1, characterized in that: The base plate is provided with a steel cage straight bar extending towards the support pile. The integrated connection seat is provided with a casting groove. The steel cage straight bar passes through the casting groove laterally. Steel fasteners are provided on both sides of the casting groove. The steel cage straight bar and the casting groove are fixedly connected by steel fasteners at the junction.
3. The basement side wall anti-floating and anti-seepage structure according to claim 2, characterized in that: Multiple pile head connecting bars are inserted into the upper end of the anti-tension pile. The multiple pile head connecting bars extend through the bottom of the integrated connecting seat into the casting groove. The ends of the multiple pile head connecting bars extending into the casting groove are bent into an L shape. The L-shaped bends of the pile head connecting bars are closely attached to the straight bars of the reinforcing cage and welded together.
4. The basement side wall anti-floating and anti-seepage structure according to claim 3, characterized in that: The bottom of the side wall is provided with multiple plug-in parts, each of which is inserted into its corresponding pouring groove. The side wall is provided with grouting holes, and grout is injected into the pouring groove through the grouting holes, so that the side wall, the straight bars of the steel cage and the pile head connecting bars are cast into a whole in the pouring groove.
5. The basement side wall anti-floating and anti-seepage structure according to claim 2 or 3 or 4, characterized in that: The lower end of the support pile is provided with a steel pre-embedded connector, and the side of the integrated connecting seat facing the support pile is provided with a connecting frame. The end of the connecting frame away from the integrated connecting seat is fixedly connected to the steel pre-embedded connector.
6. The basement side wall anti-floating and anti-seepage structure according to claim 5, characterized in that: The bottom and sides of the water collection ditch are covered with a bedding layer. When the groundwater level rises, the groundwater is filtered through the bedding layer and enters the water collection ditch.
7. The basement side wall anti-floating and anti-seepage structure according to claim 6, characterized in that: The hollow drainage cavity is equipped with at least one set of anti-reverse components. Water in the water collection ditch flows into the hollow drainage cavity through the seepage holes and is discharged unidirectionally into the soil.
8. The basement side wall anti-floating and anti-seepage structure according to claim 7, characterized in that: The anti-reverse assembly includes a reset seat, a limiting block, and a baffle. The reset seat is fixed on one side wall of the inner cavity of the anti-uplift pile, and the limiting block is fixed on the other side wall of the inner cavity of the anti-uplift pile, which is symmetrical to the reset seat. The reset seat is provided with a hinge groove, and one end of the baffle is hinged to the reset groove. A reset spring is provided between the hinge end of the baffle and the top of the hinge groove, and the other end is movably attached to the bottom of the limiting block. When draining water, the baffle flips downward away from the limiting block to achieve the drainage effect. In the case of overflow or normal conditions, the baffle abuts against the lower end of the limiting block under the action of the reset spring, isolating the upper and lower ends of the baffle.
9. The anti-buoyancy and seepage-proof structure for basement sidewalls according to claim 8, characterized in that: A water-stopping layer is provided between the integrated connector and the water storage structure.
10. The basement side wall anti-floating and anti-seepage structure according to claim 9, characterized in that: The upper end of the anti-tension pile is fitted with a water-swellable sealant at the water-stop layer, and the water-swellable sealant is covered with a waterproof rubber sleeve.
