Fish nest type organic fiber macroporous concrete retaining wall and construction method thereof

Abstract

The invention provides a fish nest type organic fiber macroporous concrete retaining wall and a construction method thereof. The retaining wall comprises an organic fiber macroporous concrete layer; the organic fiber macroporous concrete layer is formed by pouring organic fiber macroporous concrete; a plurality of fish nest holes are formed in the side face of the organic fiber macroporous concrete layer; and fish nest functional concrete is poured into the fish nest holes; the pore size of the organic fiber macroporous concrete is 5-20mm; the porosity of the organic fiber macroporous concreteis not less than 30%; the pore size of the fish nest functional concrete is 40-80mm; and the porosity of the fish nest functional concrete is not less than 40%. According to the retaining wall, the communicating holes in the organic fiber macroporous concrete are used for remarkably slowing down the water flow speed, and a place for spawning, reproduction and habitat is provided for fishes and other aquatic organisms.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and in particular relates to a fish nest type organic fiber macroporous concrete retaining wall and a construction method thereof. Background technique [0002] In order to prevent floods from scouring and eroding the bank slopes of small and medium-sized rivers, avoid embankment collapse, and improve flood control standards, it is necessary to build river bank retaining walls. Traditional revetment retaining walls for small and medium-sized rivers mainly include cast-in-place concrete retaining walls, masonry retaining walls, prefabricated concrete block retaining walls, etc. Although they can prevent the bank slope foundation from being washed by water, they also destroy fish and other aquatic organisms. growth environment. [0003] In order to provide shelter and habitat for fish and other aquatic organisms, conventional concrete prefabricated structures with smaller ent...

AI Technical Summary

Problems solved by technology

These fish nests are special-shaped three-dimensional structures prefabricated by ordinary concrete. The structure is small, the prefabrication is difficult, and the cost is high; during the construction of the retaining wall, the fish nests are transported from the prefabrication factory to the construction site and embedded in the retaining wall. , which increases the construction process, and also increases the project investment and construction period
