Ecological embankment for protecting river bank and construction method for ecological embankment

Abstract

The invention discloses an ecological embankment for protecting a river bank, and a construction method for the ecological embankment. The ecological embankment comprises prefabricated foot protecting sunken tubes and reinforced concrete inserting strips, which are longitudinally arranged on a soil slope of the embankment, geotextiles arranged at the upper ends of the reinforced concrete inserting strips, and a concrete frame and a concrete slope protecting layer which are arranged at the upper ends of the prefabricated foot protecting sunken tubes and the geotextiles, wherein the prefabricated foot protecting sunken tubes are cylindrical reinforced concrete tubes of which the middles are provided with through holes; the reinforced concrete inserting strips are arranged in gaps between adjacent prefabricated foot protecting sunken tubes; the geotextiles are arranged in the gaps prefabricated foot protecting sunken tubes through the reinforced concrete inserting strips; and the concrete slope protecting layer is arranged in the concrete frame, and is uniformly provided with reserved holes. By the ecological embankment, a bridge can be built between a water ecological system and a land ecological system, and the ecological embankment has effects of a gallery, a filter and a natural barrier on material flow, energy flow and biological flow between the water ecological system and the land ecological system, and is a perfect combination of safety, stability, landscape, ecology, naturality and hydrophily.

Description

technical field [0001] The invention relates to the field of water conservancy engineering, in particular to an ecological revetment for river bank protection and a construction method thereof. Background technique [0002] The structure of traditional water conservancy project revetment is relatively simple, and the slope is relatively smooth and hard. The revetment can realize the basic functions of the river channel such as flood discharge, waterlogging, water storage, and shipping, and stabilize the river channel, flood control and drainage, and prevent Soil erosion and other aspects play a huge role, but it has brought many adverse effects to the ecological environment. [0003] 1. The impact on the water body itself. First of all, the surface of the hard revetment is too smooth, which makes fish, amphibians, insects, birds and other animals and microorganisms closely related to human survival lose their habitat, reproduction and refuge, and various aquatic plants also...

AI Technical Summary

Problems solved by technology

As a result, the structure of the entire water ecosystem is destroyed, the original balance relationship is broken, and the self-purification ability of the water body is also greatly weakened.

In addition, the lining method of the hard revetment forms an impermeable layer between the surface and the ground, reducing the timely replenishment of groundwater by surface water, resulting in a drop in groundwater level, insufficient supply of groundwater, sinking of the ground surface, and increasing the flow of the water body itself , increasing the flood control burden

[0004] 2. Impact on the surrounding climate and environment

[0005] 3. Impact on urban landscape environment

The water environment landscape is an indispensable part of the urban landscape. The hard masonry and concrete revetment are also a kind of landscape, but it makes the river landscape obviously attached to the artificial brand and loses its natural color.
