Abstract

The utility model discloses an ecological revetment structure. The revetment structure is a slope-type smooth revetment, which comprises a slope top platform, an on-land slope protection, a dry water platform, an underwater bottom protection and an underwater protection. feet; the cross-section structure of the land slope protection that is subject to strong water flow erosion is yellow sand cushion layer, non-woven fabric layer and ecological steel wire mesh layer from bottom to top; From bottom to top, there are yellow sand cushion, non-woven fabric layer, gravel cushion and ecological hexagonal concrete block layer. The utility model adopts different types of ecological slope protection, so that the slope protection buildings are integrated with the surrounding vegetation, which fully embodies the new concept of building an environmentally friendly ecological waterway, so as to achieve the overall environmental protection protection effect.

Description

The ecological revetment structure

Technical field

The utility model belongs to the Waterway Regulation technology, is specifically related to a kind of ecological revetment structure.

Background technology

Shore protection is to exempt from for the protection of ，Shi riverbank, soil, bank a kind of water engineering facility that current scour destroys also firm river gesture, is the important component part in harbour and cruiseway engineering.In China, for the protection bank slope, control the river gesture, people have built various types of shore protections and bank protection on big and small river.

Traditional bank protection work usually be take and is prevented that flood from breaching a dyke, overflow, guaranteeing that the Economic Function such as shipping ability in human social economy and the security of the lives and property, guarantee river are target, when meeting mankind's demand, but in the demand of having ignored in varying degrees river ecosystem itself.If in the project construction processes such as water conservancy, traffic, usually stayed many exposed excavation slopes, the side slope of banketing, spoir side slope etc.; For the bank erosion that prevents that ship wave from causing, with high-strength materials such as stone, concrete, reinforcing bars to the covering of hardening of riverbed and riverbank; The excavation construction of bank slope makes original vegetational type be destroyed, and Riparian Zone land-based area ecological environment is caused and coerces; The extensive application of the grey such as cement and concrete hard material causes and coerces River Landscape.

Summary of the invention

The utility model provides a kind of ecological revetment structure that can reduce the complex condition of construction investment for solving the technical problem existed in known technology.

The technical scheme that the utility model is taked for the technical problem existed in the solution known technology is: a kind of ecological revetment structure, this bank protection structure is the smooth-going shore protection of a kind of ramp type, comprises from the slope roof panel set gradually under upper, land bank protection, low water platform, river bottom protection and spats under water under water; Be subjected to the section structure of the strong described land bank protection of current scour to be followed successively by from bottom to up yellow ground bed course, nonwoven layer and environmental gauze wire cloth compartment; Be subjected to the section structure of the weak described land bank protection of current scour to be followed successively by from bottom to up yellow ground bed course, nonwoven layer, hardcore bed and environmental hexagonal concrete piece layer.

Described low water platform adopts the paving stone structure, and the plane surface layer adopts environmental hexagonal concrete piece, and loaded filter extends to the intercepting drain outside; Described intercepting drain is arranged on roof panel back, slope, and described intercepting drain adopts the cemented rock structure; On the cemented rock wall of described intercepting drain inboard, rubble anti-filter bag and pvc pipe are set, at the closely knit native platform of described intercepting drain outside excavation, described platform rear is excavated to the top, slope; Between cemented rock, be provided with deformation joint, described deformation joint adopts foam-filled.

Described river bottom protection under water adopts D type row structure, the erosion control pillow that the edge of described D type row structure is jettisoninged perpendicular.

Described spats under water adopts the jackstone structure.

Advantage and the good effect that the utlity model has are:

1) have good permeability and modulability: by adopting ecological revetment, make nature riverbed and riverbank substrate have certain permeability, between riverbank and river water, exchange of moisture and regulatory function can be waited until fully and guarantee, its river morphology that has flood fighting intensity preferably and enrich of while.

2) reduce construction investment: adopt different ecological revetment materials according to different geological conditions, hydrologic condition, natural river bank shape and river channel erosion intensity, washing away the weak low environmental hexagonal concrete piece of area employing cost in position, washing away the stronger high environmental steel wire grid of area employing cost in position, this,, to the area of shore protection requirement is on a large scale arranged, can greatly reduce construction investment.

3) view improves greatly: by adopting ecological revetment, not only increased flood control function, also for the mankind, leisure is provided, views and admires and has got close to the multiple functions such as water body, protected to the full extent the river ecological environment to avoid destroying.

4) easy construction, renovating effect is good, and the later maintenance expense is few.
