Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel drainage ditches, in particular to a tunnel drainage ditch structure. Background Art

[0002] Tunnel construction is a new engineering construction method that uses shotcrete technology, monitoring and measurement, and a system composed of rock mechanics theory. During the construction of the tunnel, trenches need to be dug on both sides of the tunnel road surface to build drainage pipes.

[0003] The existing ones mostly use cast concrete water tank seats to be laid in the dug ditches, and then use cement to connect them one by one to form a drainage pipe, and lay a perforated cover plate formed by a steel plate on the top. Due to the solid bottom design, the bottom of the pipe formed by the water tank seat is a solid design, which can only rely on the flow of water for drainage. At the same time, the use of a leaky cover plate has no filtering structure, which will cause the pipe to accumulate debris and cause blockage. For this reason, we propose a tunnel drainage ditch to solve the above-mentioned deficiencies. Utility Model Content

[0006] Preferably, the tops of the left and right sides of the sink seat are fixedly connected with convex edges, the tops of the convex edges are provided with limiting holes, and the bottom of the cover body is integrally connected with limiting blocks adapted to the limiting holes.

[0007] Preferably, a pebble layer is provided at the bottom of the water tank seat, and a soil layer is provided at the bottom of the pebble layer.

[0008] Preferably, the slideway is T-shaped and passes through the end surface of the connecting seat.

[0009] Preferably, there are multiple through holes, which are evenly distributed at the bottom of the inner cavity of the sink seat.

[0010] Preferably, the cross-sectional width of the filter screen is greater than the width of the leakage hole.

[0011] The beneficial effects of the utility model are:

[0012] 1. The utility model adopts a leakage method through the through hole at the bottom of the inner cavity of the water tank seat to improve the drainage effect. At the same time, the shaft is rotated on the inner surface of the cylinder to rotate and open the connecting seat, and the filter screen is slid into the slideway inside the connecting seat through the sliding block. The water flow will flow through the filter screen through the leakage hole, and the debris will be filtered by the filter screen. By setting the above structure, the purpose of leakage drainage and filtering debris is achieved;

[0013] 2. The utility model provides a limit block that is integrally connected to the bottom of the cover body and matches the limit hole, so that the connection between the cover body and the convex edge is more stable and the connection position is limited;
