Description

Ecological revetment structure of urban mountain river course

Technical Field

The utility model relates to a river course ecological management field especially relates to an ecological bank protection structure for be applied to city mountain area river course.

Background

In recent years, the ecological construction of river channels is more and more emphasized. The mountainous river channel has the characteristics of large slope drop, high flow velocity, large water level change amplitude, strong scouring force, poor soil, poor water retention and the like, and the selection of the ecological bank protection type is relatively difficult. The traditional treatment engineering of mountain river channels rarely combines the characteristics of regions and the actual conditions to consider the landscape effect. The embankment has obvious artificial traces, often gives monotonous and harsh feeling to people, has typical engineering technical characteristics, and is deviated from the landscape demand and psychological expectation of modern people pursuing to return to nature and harmonious with nature. Therefore, the method has important significance in the aspects of flood control, ecological environment improvement, water quality protection, harmonious harmony between human and nature and the like when ecological construction is carried out on mountainous river channels.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides an ecological bank protection structure in city mountain area river course, this ecological barricade of it can enough satisfy flood control safety, can satisfy the ecological construction of river course again.

An ecological revetment structure of river course in urban mountain area, technical scheme is: the revetment structure comprises an ecological block wall, a stone-buried concrete wall and a grouted water-washed stone retaining wall; the ecological block wall body is positioned between the design flood level and the design dyke top, the stone-buried concrete wall body is positioned below the ecological block wall body, the bottom plate of the stone-buried concrete wall body is buried below the design river bottom line, and the front side wall of the stone-buried concrete wall body is positioned at the design river mouth line; the front of the stone-buried concrete wall is provided with a grouted water-washed stone retaining wall, and a base of the grouted water-washed stone retaining wall is buried below a designed river bottom line.

Based on the technical characteristics: a hydrophilic footpath is arranged between the stone-buried concrete wall and the grouted water-washed stone retaining wall, and a planting groove is arranged between the hydrophilic footpath and the stone-buried concrete wall.

Based on the technical characteristics: the front edge of the grouted water-washed stone retaining wall is provided with an egg-floating rockfill protection foot.

Based on the technical characteristics: the ecological block wall body is formed by splicing ecological blocks up and down and left and right, and the ecological blocks on the upper layer retreat and are arranged in a staggered manner with the ecological blocks on the lower layer; a single ecological building block is a box body, and broken stones and soil are filled in the box body and plants are planted in the box body.

Based on the technical characteristics: the buried stone concrete wall is a gravity type retaining wall formed by mixing concrete with natural stones; the stone-buried concrete wall includes a wall body and a bottom plate.

In the above technical scheme: the ecological block wall can utilize the blocks to retain soil, and the inner lining geotextile is arranged in the box body and filled with gravels, soil and the like, so that water body exchange is increased, and living space is provided for aquatic animals; meanwhile, grass seeds can be sown in the building blocks to form wall greening, and the landscape of the river channel is improved. The nutrient soil layer can provide nutrients for the grass seeds in the ecological block wall body in the early growth stage, the growth speed is high, and therefore the survival rate of the grass seeds is improved. Thus, the ecological property of the river channel can be realized.

The buried concrete wall body is used as a main body structure of the revetment for retaining soil, and the buried concrete in the wall body can reduce the consumption of concrete, save investment and reduce the hydration heat of the concrete.

The grouted water stone-flushing retaining wall is used as a foot guard of the stone-buried concrete wall, so that the scouring of water flow to the stone-buried concrete wall can be reduced, and the safety of the main structure is protected.

The grouted water stone-flushing retaining wall is used as a small retaining wall structure and is combined with a stone-buried concrete wall body to form a hydrophilic footpath space. The hydrophilic footpath mainly provides hydrophilic measures for tourists, and increases the hydrophilicity and the playability of the riverway. Greening is arranged in the planting groove, so that the landscape of the river channel is enhanced; meanwhile, the greening plants can purify water and improve water quality.

This ecological bank protection can enough satisfy flood control safety, can satisfy view greening effect again, has increased the functional demand that the ecological hydrophilic of river course was exchanged simultaneously.
