Detailed Description

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

Referring to fig. 1, 2 and 3, the drainage ditch structure comprises a drainage ditch body 5 and a plurality of rectangular drainage grates 2, wherein all the drainage grates 2 are longitudinally arranged on the top of the drainage ditch body 5 side by side along the drainage ditch body 5; a concrete layer 4 is poured on the inner wall of the drainage ditch body 5, and the bottom of the inner wall of the concrete layer 4 is transversely in a circular arc structure with high parts at two sides and low parts at the middle part along the drainage ditch body 5, so that the inner wall of the concrete layer 4 is in a U-shaped structure; and the inner wall of the concrete layer 4 is provided with a waterproof layer 3 for avoiding the infiltration of water in the drainage ditch.

When the concrete layer is poured, arc-smearing treatment is carried out on two corners of the drainage ditch body, so that the inner wall of the concrete layer is in a U-shaped structure, the connection strength of the bottom of the drainage ditch and the connection parts of the two sides can be improved, and water in the drainage ditch can be effectively prevented from leaking from the connection parts of the two sides; meanwhile, the water in the drainage ditch is convenient to discharge in time, and the possibility of infiltration of the water in the drainage ditch is reduced; and the waterproof layer is arranged, so that the seepage-proofing performance of the drainage ditch can be further improved.

In specific implementation, the two side walls of the concrete layer 4 have height difference, the height difference of the two side walls corresponds to the thickness of the drainage grate 2, wherein the higher side wall is a first side wall, the other side wall is a second side wall, the first side wall is close to the foundation pit side, and the upper surface of the first side wall is flush with the upper surface of the corresponding side of the drainage ditch body 5; the second side wall has a height difference with the upper surface of the corresponding side of the drainage ditch body 5, so that a sinking platform is formed on the side of the drainage ditch body 5; the lower opening of one side of each drainage grate 2 is placed on the sinking platform and is abutted against the corresponding side of the drainage grate body 5, and the upper opening of the opposite side of the drainage grate 2 is lapped on the first side wall of the concrete layer 4 through the lapping piece 1.
