Ecological Restoration Structure and Method for Enhancing Undercurrent Exchange

Abstract

The invention discloses an ecological remediation structure enhancing phreatic zone exchanging and belongs to the field of ecological remediation structures preventing river bank erosion. The whole ecological remediation structure is a W-shaped rock block weir and is composed of protection arms, an inner arm and dam abutments. The inner arm is arranged at the center of a river way, the protectionarms are arranged on the two sides of the river way and connected with the dam abutments, and the dam abutments on the two sides perpendicularly stretch into river banks. The ecological remediation structure has multiple functions of enhancing exchanging between surface water and underground water, enhancing the purification effect of a phreatic zone, protecting a river way ecological system, preventing river bank erosion and the like. Compared with a traditional river channel improvement method, the ecological remediation structure has the beneficial effects that a river way surface water andgroundwater system is comprehensively considered, and the purification effect of the river way phreatic zone is given play to; and the cost is low, needed manpower is small, construction is easy, theecological remediation function can be maintained for a long term, and the application prospects in the fields of river way ecological remediation, river bank protection and the like are very wide.

Description

technical field [0001] The invention relates to an ecological restoration structure for preventing and controlling river bank erosion, in particular to an ecological restoration structure and method for enhancing subsurface flow exchange. Background technique [0002] In recent years, with the improvement of industrial and agricultural production levels, the problem of water pollution caused by pollutant discharge has become increasingly serious. In the upper reaches of rivers, especially in mountainous areas, excess chemical fertilizers, pesticides, livestock and poultry manure and other pollutants produced during agricultural production flow into rivers, causing a series of ecological problems in mountainous watersheds. The river is a complete continuum, and the surface water of the river channel, the left and right banks and the bottom of the river bed form a complete system. The connectivity of surface water in a channel to the surrounding groundwater constitutes an imp...

Problems solved by technology

However, protection measures such as traditional hardening of river banks will split the surface water and groundwater systems, causing disasters such as ecosystem degradation.
