Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiment of the utility model discloses advanced stagnant water seepage prevention structure of bottom plate post-cast strip.

Referring to fig. 1, the advanced water-stop anti-leakage structure of the floor post-cast strip comprises a concrete cushion layer 1, a waterproof layer 2, a water-stop strip layer 3 and an advanced water-stop bottom arch layer 4.

The concrete cushion layer 1 is poured at the bottom of the reserved post-cast strip and is laid on the ground on two sides of the bottom plate post-cast strip. The upper surface of the concrete cushion layer 1 is in an arch shape protruding downwards, namely the section of the upper surface of the concrete cushion layer 1 is in an arc shape.

Referring to fig. 1, a waterproof layer 2 is laid on the upper surface of a concrete mat 1, and the waterproof layer 2 is laid on the concrete mat 1 on both sides of a floor post-cast strip. The waterproof layer 2 may be a waterproof structure formed by combining a plurality of waterproof roll material layers.

The waterproof tape layer 3 is placed at the upper end of the waterproof layer 2, and the waterproof tape layer 3 is located at the lowest point of the arched bottom of the waterproof layer 2. The waterstop layer 3 comprises a buried waterstop 31 and an externally-attached waterstop 32; the outer water stop 32 is plate-shaped and laid on the bottom of the waterproof layer 2, the middle water stop 31 is also plate-shaped, and the middle water stop 31 is vertically arranged on the upper end of the outer water stop 32. The external waterstop 32 can be provided with two layers, and the second external waterstop 32 is fixedly adhered to the side wall of the buried waterstop 31.

Referring to fig. 1, the advanced water-stopping bottom arch layer 4 is provided with the upper end of the waterproof layer 2, and the advanced water-stopping bottom arch layer 4 is a concrete layer and is formed by pouring conventional concrete. Wrap up sealing-up belt layer 3 when leading sealing-up bottom hunch layer 4's concrete placement, but sealing-up belt layer 3's well top of burying sealing-up belt 31 need expose leading sealing-up bottom hunch layer 4, the upper surface of leading sealing-up bottom hunch layer 4 is decurrent arch, and is preferred, and the minimum point department of the bottom of leading sealing-up bottom hunch layer 4 is the same with the top height of burying sealing-up belt 31 in, and the minimum point department of leading sealing-up bottom hunch layer 4 is the same with sealing-up belt layer 3's top height promptly to the top of burying sealing-up belt 31 in can expose.
