Abstract

The utility model discloses an ecological recovering type bank protection structure in riverway beaches, which relates to a riverway beach bank protection structure, and provides a bank protection structure consisting of a non-watertight type river bank power protected zone, a beach ecological system constructing zone and a nature imitating bank zone. The bank protection structure consists of the non-watertight type river bank power protected zone, the beach ecological system constructing zone and the nature imitating bank zone. The utility model is characterized in that the river bank power protected zone adopts jackstones and manual lump material fill and performs the surface building; the top height of the river bank power protected zone is the sum of the designed high water level and 0.1 to 0.5 m; and opening sections are partially arranged at intervals. The water surface width of the beach ecological system constructing zone is larger than or equal to 1m; the water depth in the ordinary water level is larger than or equal to 0.2m; and emergent aquatic plants, floating/leaf plants and hydrophilous plants are planted in the beach ecological system constructing zone. The nature imitating bank zone protects sloping surfaces by planting grass bricks and filling small stones and geogrids to form natural bank slopes. The utility mode is suitable for bank protection in riverwasy and waterways.

Description

Shore, river course bank band ecological recovery type bank protection structure pattern

Technical field

The utility model relates to the structural shape of shore, a kind of river course bank shore protection.

Background technology

The conventional shore protection in river course comprises the structural shape of revetment, flood-control wall, and generally the wall body structure pattern by single wall body structure pattern such as cemented rock wall body, reinforced concrete wall body, step constitutes.

Single wall body structure pattern generally adopts cemented rock wall body, reinforced concrete wall body, its outward appearance neat appearance; But the wall body structure is vertical type, the discrepancy in elevation is bigger, causes shore, river course bank band ecological functions weakness, can not create conditions for the biological existence and the recovery of shore, river course bank band.

The wall body structure pattern of step generally is that single wall body structure pattern is divided into two joint or more pieces, forms notch cuttype, and the centre is provided with platform, its outward appearance neat appearance, and hydrophily is better.But the wall body structure also is vertical type, though the discrepancy in elevation reduces, but still can not satisfy of the reasonable transition of shore, river course bank band water area ecological environment, cause shore, river course bank band ecological functions weakness, can not create conditions for the biological existence and the recovery of shore, river course bank band to the land-based area ecological environment.

Under the present situation situation that environmental protection requirement improves day by day, the shore protection construction needs to develop to the ecology direction, considers that the ecological functions of bank protection structure pattern seem particularly important, and design ecology typed bank revetment structural shape is the development trend of environmental protection.

The utility model content

The utility model technical issues that need to address provide a kind of bank protection structure pattern that adopts permeable type riverbank power buffer zone, bank ecological system constructing band and imitative nature bank slope band three parts to form, overcome the shortcoming of the wall body structure pattern ecological functions weakness of single wall body structure pattern, step, embody the ecology advantage of bank protection structure pattern.

The technical solution of the utility model is made up of permeable type riverbank power buffer zone, bank ecological system constructing band and imitative nature bank slope band, it is characterized in that riverbank power buffer zone adopts jackstone, artificial block materials to throw and fill out, and carry out the surface reason and build, riverbank power buffer zone crest level is that design high-water adds 0.1～0.5m, and the part is provided with open section at a certain distance; Bank ecological system constructing band water surface width 〉=1m, the depth of water 〉=0.2m during ordinary water level plants emergent aquactic plant, swims/the leaf plant, likes the water hygrophyte; Imitative nature bank slope band adopts the grass planting brick, fritter stone is filled out in throwing, geo-grid is carried out slope protection, forms imitative natural type bank slope.

Structural shape of the present utility model has overcome the shortcoming of the wall body structure pattern ecological functions weakness of single wall body structure pattern, step, and have the advantage of wall body structure pattern and step wall body structure pattern concurrently, riverbank power buffer zone has good water permeability, but can keep out the dynamic action of ship wave, current and wave; Bank ecological system constructing band provides and has created a good living environment for shore, the river course bank band ecosystem; Imitative nature bank slope band is for building the transitional environment from the waters to the land-based area that is beneficial to plant growing; The good hydrophilic property technology is reliable, and is durable in use, cost is lower, is applicable to the structural shape of river course, navigation channel shore protection.

The specific embodiment

Below in conjunction with the description of drawings specific embodiment of the present utility model:

The utility model is made up of permeable type riverbank power buffer zone 1, bank ecological system constructing band 2 and imitative nature bank slope band 3 three parts; Riverbank power buffer zone 1 adopts jackstone or artificial block materials 4 to throw and fills out, and carry out surface reason and build and form, riverbank power buffer zone 1 crest level is the rich height that design high-water adds 0.1～0.5m, and the part is provided with open section 9 at a certain distance, forms the safeguard structure that has pervious function and resist current, ship wave destruction function; Bank ecological system constructing band 2 water surface width 〉=1m, the depth of water 〉=0.2m during ordinary water level, plant emergent aquactic plant, swim/the leaf plant, like water hygrophyte 5, the space of perching, laying eggs and breed for aquatic animal provides is recovering naturally and the good condition of creation that develops in a healthy way of shore, river course bank band aquatic animal; Imitative nature bank slope band 3 adopts grass planting brick, throwing to fill out fritter stone, geo-grid is protected domatic 6 and laid, for building 8 transitional environments that are beneficial to plant growing to land-based area from the waters, utilize the solid soil 7 of plant 5 (containing Qiao, shrub) root system, imitative nature bank slope band recovers natural form, and have the erosion damage function of keeping out rainwater and overland flow, form complete bank protection structure.

Claims

1, shore, river course bank band ecological recovery type bank protection structure pattern, form by permeable type riverbank power buffer zone, bank ecological system constructing band and imitative nature bank slope band, it is characterized in that riverbank power buffer zone adopts jackstone, artificial block materials to throw and fill out, and carry out the surface reason and build, riverbank power buffer zone crest level is that design high-water adds 0.1～0.5m, and the part is provided with open section at a certain distance; Bank ecological system constructing band water surface width 〉=1m, the depth of water 〉=0.2m during ordinary water level plants emergent aquactic plant, swims/the leaf plant, likes the water hygrophyte; Imitative nature bank slope band adopts the grass planting brick, fritter stone is filled out in throwing, geo-grid is carried out slope protection, forms imitative natural type bank slope.
