Anti-silting intercepting ditch assembly and intercepting ditch adopting same

Abstract

The invention discloses an anti-silting intercepting ditch assembly. The assembly is a prefabricated part and comprises a bottom groove body and a top water permeable groove cover, wherein the two ends of the bottom groove body are open, the bottom groove body is of a concrete structure, the cross section of the bottom groove body is an isosceles trapezoid, and the upper bottom of the bottom groove body is longer than the lower bottom of the bottom groove body; and the top water permeable groove cover is of a concrete structure formed by pouring non-fine concrete, the cross section of the top water permeable groove cover is in an upwards-arched arc shape, the top water permeable groove cover is buckled on a top opening of the bottom groove body in a matched mode, and the two ends of the top water permeable groove cover are flush with the two ends of the bottom groove body. The invention further discloses an intercepting ditch adopting the anti-silting intercepting ditch assembly. The intercepting ditch is formed by sequentially splicing and building a plurality of anti-silting intercepting ditch assemblies in the longitudinal direction. According to the anti-silting intercepting ditch assembly and the intercepting ditch adopting the same, the functions of preventing silting of the intercepting ditch and keeping a revetment complete and stable can be achieved, the construction efficiency can be effectively improved, the construction labor consumption and the rock block consumption can be reduced, and the design and construction requirements of various slope type revetment intercepting ditches of different structures can be met.

Description

technical field [0001] The invention relates to an assembly of an intercepting ditch, in particular to an assembly of an anti-silting intercepting ditch and an assembly of the intercepting ditch using the assembly. Background technique [0002] The interception ditch is also called the diversion ditch and the flood diversion ditch. It is a drainage ditch built on the top of the slope parallel to the contour line or near the parallel contour line. The bottom of the ditch has a certain slope. The function is to guide the runoff on the upper slope to the revetment open ditch, and protect the lower revetment slope from erosion. The cross-sectional form of the intercepting ditch is generally trapezoidal or rectangular, and the intercepting ditch is connected with the vertical drainage ditch. The common form of revetment in water conservancy and waterway improvement projects is slope revetment, which consists of three parts: land revetment, dry water platform and underwater botto...

AI Technical Summary

Problems solved by technology

At present, the design of the interception ditch generally adopts the structure of stone masonry or stone masonry and face-protecting bricks. The existing structure mainly has problems such as the construction process consumes a lot of labor, the quality is difficult to control, and sediment is easy to accumulate in the interception ditch, which leads to the loss of efficacy of the interception ditch. It is urgently needed The adoption of a new structure can not only improve the project quality and construction efficiency requirements, but also give full play to the project effect for a long time, and avoid the problem of interception ditch failure caused by siltation
