Detailed Embodiments

[0019] The present utility model will be further described below with reference to the drawings.

[0020] A waterproof structure for a basement bearing platform. The basement bearing platform includes a pile foundation 2 constructed and formed in a foundation pit 6 and a bearing platform 1 located above the pile foundation 2. The waterproof structure is arranged between the pile foundation 2 and the bearing platform 1 to prevent water leakage at the bearing platform 1 of the basement. The waterproof structure includes a waterproof construction layer 3, a pile-end waterproof member 4, and a pouring layer 5. The waterproof construction layer 3 is arranged around the pile foundation 2 to waterproof the connection surface between the foundation pit 6 and the pile foundation 2. The pouring layer 5 is arranged above the waterproof construction layer 3 to protect the waterproof construction layer 3 through the pouring layer 5 and improve the service life of the waterproof construction layer 3. The pile-end waterproof member 4 is fixed at the end of the pile foundation 2 and abuts against the waterproof construction layer 3 to waterproof the connection surface between the pile foundation 2 and the pouring layer 5. The bearing platform 1 is cast and formed above the pile foundation 2, so that the pile-end waterproof member 4 is located between the bearing platform 1 and the pile foundation 2. When the bottom width of the bearing platform 1 is relatively large, the bearing platform 1 is connected to the waterproof construction layer 3.

[0021] To further improve the waterproof performance of the pile-end waterproof member 4 for the pile foundation 2, the pouring layer 5 wraps around the outside of the pile-end waterproof member 4 to fix the pile-end waterproof member 4 through the pouring layer 5 and prevent the pile-end waterproof member 4 from deforming and affecting its waterproof performance. When the pile-end waterproof member 4 is wrapped in the pouring layer 5, the bearing platform 1 is cast and formed above the pouring layer 5, and it is ensured that the bearing platform 1 and the pile foundation 2 are connected through a steel reinforcement cage.

The end water stop belt 4-2 covers the outside of the side water stop belt 4-1 and the pile foundation 2 to waterproof the top of the pile foundation 2 and ensure the overall waterproof performance of the top of the pile foundation 2.

[0023] Among them, the side water stop belt 4-1 is square or cylindrical, and different side water stop belts 4-1 can be selected according to the cross-sectional shape and size of the pile foundation 2. The side water stop belt 4-1 includes a vertical cylindrical part 4-4 and a bent part 4-5. The cylindrical part 4-4 is sleeved outside the pile foundation 2, and the bent part 4-5 abuts against the waterproof construction layer 3 to waterproof the connection between the waterproof construction layer 3 and the pile foundation 2. Preferably, the top of the side water stop belt 4-1 is higher than the upper end surface of the pile foundation 2 to ensure that the end water stop belt 4-2 abuts against the side water stop belt 4-1.

[0024] A connection ring 4-3 is provided at the edge of the end water stop belt 4-2, and a sealing gasket 4-6 is provided inside the end water stop belt 4-2. The sealing gasket 4-6 abuts against the side water stop belt 4-1. Preferably, the edge of the sealing gasket 4-6 extends to the inside of the connection ring 4-3, so that the sealing gasket 4-6 abuts against the side wall of the side water stop belt 4-1 to further improve the waterproof performance of the top of the pile foundation.

[0025] The pile foundation 2 is provided with pile foundation steel bars 2-1. The top of the pile foundation steel bars 2-1 extends out of the upper end face of the pile foundation 2. External threads are provided on the outer side of the pile foundation steel bars 2-1. The end water stop 4-2 is fixed on the end face of the pile foundation 2 through nuts 2-2, ensuring that the gasket 4-6 is in a compressed state, and realizing the tight connection between the end water stop 4-2 and the side water stop 4-1. After the installation of the end water stop 4-2 is completed, waterproof paint is coated at the connection between the nut and the end water stop 4-2, thereby preventing water leakage at the pile foundation steel bars 2-1. As a preferred implementation manner, the pile foundation steel bars 2-1 extending out of the top of the pile foundation 2 can be connected to the steel cage in the bearing platform 1 to improve the stability of the bearing platform 1.
