Fish nest type hinge rows and underwater bank protection structure adopting same

Abstract

The invention discloses fish nest type hinge rows. The fish nest type hinge rows are a block body with an I-shaped cross section, four corner parts of the hinge rows are correspondingly provided with occlusion teeth, the left sides and the right sides of the hinge rows are correspondingly provided with occlusion tooth grooves, the middles of the hinge rows are provided with vertically-through fish nest holes, and the occlusion tooth grooves can occlude two occlusion teeth which are arranged in parallel up and down, the invention further discloses an underwater bank protection structure adopting the fish nest type hinge rows, the underwater bank protection structure comprises a plurality of fish nest type hinge rows fully laid on a slope surface, the fish nest type hinge rows are arranged in rows up and down, every two rows of fish nest type hinge rows adjacent left and right are arranged in a staggered mode, two adjacent occlusion teeth of the two staggered fish nest type hinge rows mesh with each other, and two occlusion teeth which are parallel up and down mesh with the occlusion tooth grooves. The fish nest type hinge rows and the underwater bank protection structure adopting the same can meet the requirements for stability, ecology and safety of the underwater bank protection structure.

Description

technical field [0001] The invention relates to a revetment structure, in particular to an underwater revetment structure. Background technique [0002] For restrictive waterways with narrow river width, in addition to the influence of current conditions, ship waves are also a strong hydrodynamic factor, which is the main dynamic factor for bank slope damage. In order to effectively prevent the instability and damage of the bank slope in the wave impact area under the influence of the ship's traveling waves, hard protective structures such as cast-in-place concrete panels are often used for restricted waterways below the normal water level. This kind of hard protective structure helps to resist the scour of hydrodynamic forces such as ship waves, protect the structural stability of the slope protection engineering slope, and prevent soil erosion. But at the same time, there are also the following problems: First, the relationship between the water body and the soil has been...

AI Technical Summary

Problems solved by technology

But at the same time, there are also the following problems: First, the relationship between the water body and the soil has been completely severed, and the resource function and ecological function of the river have been destroyed.

The second is to occupy the habitat space of fish and shrimp and other organisms, and destroy the living environment of aquatic organisms

The third is that the surface of the concrete panel forms a smooth surface with minimal resistance under water, which is not conducive to the survival of people who fall into the water
