In order to achieve the above purpose, the utility model adopts the technical scheme that: the anti-seepage structure of the drainage pipeline comprises a drainage pipe penetrating into a base floor slab, wherein the top end of the drainage pipe is not higher than the top surface of the base floor slab, a waterproof layer is formed by applying the top surface of the base floor slab, and the waterproof layer extends uninterruptedly from the base floor slab to the inner wall of the drainage pipe to form a protective part.

The further improved scheme in the technical scheme is as follows:

1. in the above scheme, the top surface of the drain pipe is flush with the top surface of the base floor slab.

2. In the scheme, the top surface of the drain pipe is 2-10 mm lower than the top surface of the base floor slab.

3. In the scheme, the distance between the bottom end of the protection part and the top end of the drain pipe is 2-8 mm.

4. In the scheme, the corner of the drain pipe of the waterproof layer extending into the base floor slab is chamfered with an oblique angle and forms an annular flow guide part with the corner.

5. In the above scheme, the thickness of the waterproof layer far away from the drain pipe is larger than that of the waterproof layer around the drain pipe.

Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:

1. the utility model discloses drainage pipe's seepage prevention structure, it is through setting up the drain pipe in basic unit's floor, basic unit's floor top surface is not stretched out on the control drain pipe top, avoid convex drain pipe wall to block the infiltration entering drain pipe on the basic unit's floor, and simultaneously, brush formation waterproof layer on the basic unit's floor, and form waterproof portion in extending into the drain pipe with the waterproof layer, can avoid ponding from the clearance infiltration between basic unit's floor and the drain pipe, ponding entering drain pipe can be led again, abundant discharge ponding, protect building structure, prolong its life.

2. The utility model discloses drainage pipe's seepage prevention structure, its corner part through brushing at the waterproof layer forms the annular water conservancy diversion portion that has the oblique angle, cooperates the difference in height setting of low in the outer height, and direction ponding gets into the drain pipe.
