Description

Ecological guiding device in water environment restoration

Technical Field

The utility model relates to an aquatic ecological remediation field, in particular to rivers guiding device among the aquatic ecological remediation.

Background

With the development and deepening of ecological restoration research on rivers and lakes, many ecological restoration measures begin to emphasize the hydrodynamic characteristics of areas. The terrains of partial rivers and lakes in cities are complex and the residence time is long. The occurrence of water pollution is dispersive, the result of water pollution is integral, and the water pollution remediation needs to be based on the aspect of an area and break the division of strips and blocks. The diversion is an engineering regulation and control measure for solving the allopatric contradiction in the water ecological restoration process and realizing the spatial reconfiguration of water resources, and the diversion can break the dead water areas of rivers and lakes and enhance the effects of other water ecological restoration measures. The traditional diversion only changes the spatial distribution of pollutants, does not eliminate any pollutants, and the traditional structure adopts a large amount of steel bars and concrete, is troublesome to construct and is not an ecological material.

Preferably, the timber pile is made of fir, and the distance between the timber piles on the same side is 40 cm.

Preferably, the height of the wooden pile above the water surface is 20 cm.

Preferably, the geotextile is arranged 10cm below the water surface.

Preferably, the thickness of the second gravel layer is 10 cm.

Preferably, the baffle plate and the timber pile are fixed through fixing nails.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the guiding device can guide the flow direction of water flow, and water distribution can be well carried out by combining with some hydrodynamic devices.

2. The diversion device is made of ecological materials and is environment-friendly.

3. By adding gravel into the flow guide device, an attachment carrier of microorganisms is provided, a biological membrane is formed, and water quality is purified.

4. Emergent aquatic plants are planted on the gravels, so that the environment can be beautified, and the landscape effect is improved.
