Description

Communicated fish nest brick

Technical Field

The utility model relates to a protection ecological environment field of river regulation, concretely relates to intercommunication formula fish nest brick.

Background

In order to implement the concept of 'ecological priority and green development', an engineering structure scheme is optimized, the river regulation engineering adopts low-strength channel management methods such as an environment-friendly structure, and the like, and the ecological prevention and restoration engineering measures slow down the adverse environmental impact of the engineering on the structure function of the ecological system. Wherein, the fish nest brick can provide a habitat for fish spawning, porpoise foraging and the like. The single-hole fish nest brick can provide limited ecological space for living environment of underwater organisms such as fish and the like.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art and provide a communicated fish nest brick which solves the problems of the single-hole fish nest brick and is used for building an ecological structure of living environment of underwater organisms such as fish and the like in river regulation engineering; so that the function of creating living environment of underwater organisms such as fish can be better exerted.

In order to achieve the above object, the utility model provides a intercommunication formula fish nest brick, including the brick body, the brick body is the hollow square body, the hole that link up each other is seted up to three sides of the brick body, the internal bottom surface of brick forms the slope bottom surface towards a hole slope to brick body wall, and this hole is the inclined hole, and two other holes are parallel holes.

Further, the inclined bottom surface has an inclination angle α of 3 to 5 °.

Still further, the brick body is a cube.

Furthermore, the side length of the brick body is 1m, and the width and the height of the holes on the two sides are 45cm and 50cm respectively; the widths of the inner hole and the outer hole of the inclined hole are 50cm and 55cm respectively, and the depth of the inclined hole is 70 cm.

Furthermore, the upper wall thickness and the lower wall thickness of the brick body are respectively 25cm and 20cm-25cm, the left wall thickness and the right wall thickness are 25cm, and the rear wall thickness is 30 cm.

The concrete strength of the communicated fish nest brick is C₂₀Single member volume 0.704m³The weight was 1654 kg.

Compared with the single-hole fish nest brick (the cavity size is 50 x 50cm), the communicated fish nest brick of the utility model has the advantages that:

1. the utility model discloses a intercommunication formula fish nest brick is multidirectional, can provide bigger ecological space for organisms such as fish under the water, and organisms such as fish under water can hide inside three hole intercommunication formula fish nest bricks, receives the influence of human activity littleer, consequently, three hole intercommunication formula fish nest bricks more are favorable to biological reproduction and existence such as fish under water to reach the ecological purpose of building biological living environment such as fish.

2. The utility model discloses promote microorganism at fish nest brick ingrowth, build functions such as fish living environment.

3. The test section is monitored for benthonic animal density, biomass, fish and the like. 10 benthos with biomass of 1.59g/m were collected before construction²After construction, 8 benthos with biomass of about 0.834g/m are collected²Compared with the method before construction, the method reduces 48 percent, 10 benthos are collected 6 months after construction, and the biomass is about 1.92g/m²Compared with the prior art, the method increases the cost by 21 percent. Benthic organisms are found in the fish nest brick to recover quickly after the engineering. And benthic organisms such as limnodrilus, limnoperna lacustris, corbicula fluminea, freshwater shrimps and the like are found in each fish nest brick, which shows that the fish nest brick has the function of providing ecological environment conditions for the survival of organisms such as underwater fish and the like.

Detailed Description

The invention is described in further detail below with reference to the figures and specific embodiments for the understanding of those skilled in the art.

The communicated fish nest brick shown in the figures 1-5 comprises a brick body, wherein the brick body is a hollow cube, the upper wall thickness and the lower wall thickness of the brick body are respectively 25cm and 20cm-25cm, the left wall thickness and the right wall thickness are respectively 25cm, and the rear wall thickness is 30 cm;

three side surfaces of the brick body are provided with through holes 1, and the width of the parallel holes 1.2 at two sides is 45cm and the height is 50 cm;

the inner bottom surface of the brick body is inclined to the wall of the brick body to form an inclined bottom surface 2 with an inclination angle alpha of 4 degrees, the hole 1 is an inclined hole 1.1, the widths of an inner hole and an outer hole of the inclined hole 1.1 are respectively 50cm and 55cm, and the depth is 70 cm.

According to actual conditions, the communicated fish nest bricks are installed on the bed of the underwater bank slope river of the river channel, and the installed roof elevation is generally below the backest water level of the river channel. The three-hole communicated type fish nest brick is arranged at intervals of 2cm and is arranged close to each other, so that the inner spaces of the three-hole communicated type fish nest bricks are communicated with each other (figure 6).
