Description
Technical field
The utility model relates to a kind of wall-retaining structure, particularly navigation channel, a kind of green ecological river shore protection wall-retaining structure.Belong to slope protection works field, be applicable to greening and require high, to take into account amphibious ecology slope protection works near water.
Background technology
Navigation channel, river bank protection work is that protection river bank is avoided current, stormy waves invasion and attack and washes away taked engineering measure.Conventionally the bank protection structure in river course mainly adopts and grouts or placed rockfill shore protection, cast-in-situ concrete shore protection, precast concrete block shore protection etc.; but the stone masonry barricade that these are traditional and concrete guard wall have only played the effect of a protection soil erosion; because of its water permeability poor; blocked the ecological linkage between river and two sides soil; make many water plant disappearance living environments, thereby reduced the self-detergent power of water body.
Green ecological shore protection barricade requires both to have met river course slope protection function, be conducive to again recover river course slope protection system ecology balance, mainly pass through planting plants, the reinforced action of shallow root and plant utilize the anchorage effect of plant deep root, can reduce slope body pore water pressure, rainfall interception, reducing erosion, the loss of control grogs, recover the destroyed plurality of advantages such as ecological environment, reaching shore protection, prevent erosion and improve the effect of environment, is a kind of cost-effective shore protection, solid bank engineering.External research aspect river channel ecology slope protecting technique wants Zao than domestic starting, and Japan just proposed " hydrophilic " idea before 10 years.
At present, the domestic ecological revetment type of skill generally adopting mainly contains vegetation grass, hydraulic spray of grass seeds grass planting, earth working material afforestation, vegetation type eco-concrete, cement ecological planting matrix, soil-solidified-agent etc.But often in application, form is single, can not suit measures to local conditions, cause that plant survival rate is low, soil erosion, the shortcoming such as seasonal restriction is large, resistance to overturning is poor, and most of ecological revetment barricade cost and later maintenance cost high, on processing, can not take into account aspect land and water two ecological.
Given this, not enough in order to solve existing ecological revetment barricade stability, the shortcomings such as Ecological Disposal is not comprehensive, need that invention is a kind of can meet navigation channel, the green ecological river shore protection wall-retaining structure that stability is strong, take into account the multipurposes such as land and water ecology, easy construction is effective, good in economic efficiency simultaneously at present badly.
Summary of the invention
The purpose of this utility model is to provide that a kind of stability is high, easy construction, take into account amphibious ecology and good navigation channel, the green ecological river shore protection wall-retaining structure of economic benefit.
In order to realize above-mentioned technical purpose, the utility model has adopted following technical scheme:
Navigation channel, a green ecological river shore protection wall-retaining structure, barricade more than ordinary water level near water side and end face build eco-concrete layer, and the vegetation of planting, barricade is the following random reserving hole of side ordinary water level near water; After barricade, from bottom to top lay successively slabstone layer of concrete, plantation back fill course, and at slabstone layer of concrete end face and barricade inside wall, root separation film is set; In the following soil layer in bottom surface of slabstone layer of concrete, L-type gutter is set, L-type gutter is through barricade, and end connects purification header tank.Purify header tank setting and be fixed on barricade near water on the reserved notch of side, higher than ordinary water level 500 ~ 1000mm, can many gutters share and purify header tanks, underground water is collected to purify after header tank purifies through gutter and drains in river course.
Described L-type gutter along the river direction along ng a path is equidistantly laid, the interval perforate of vertical drainage section entire body, and outsourcing anti-filter geotextiles, and transverse drainage section pipe shaft is closed tube.
The utlity model has following feature and beneficial effect:
(1) the L-type gutter with holes of outsourcing anti-filter geotextiles is conducive to the timely discharge of water after barricade, reduces the lateral earth pressure of barricade, strengthens whole structural stability.
(2) gutter port arranges purification header tank, and the water that can guarantee to enter navigation channel, river is pollution-free.
(3) barricade near water side build eco-concrete, and plant hygrophyte, both can utilize plant roots and stems to play reinforced action, have again environmental protection effect.
(4) the barricade following random reserving hole of side ordinary water level near water, perches and grows for aquatic animals and plants such as fish, shrimps.
In a word, adopt shore protection wall-retaining structure described in the utility model can improve barricade stability, soil erosion after minimizing wall, and take into account land and water ecology.
Accompanying drawing explanation
Fig. 1 is navigation channel, the utility model green ecological river shore protection wall-retaining structure cross-sectional drawing;
In figure: 1-barricade, 2-L type gutter, the common back fill course of 3-, 4-root separation film, 5-slabstone layer of concrete, 6-kind is planted backfill, 7-eco-concrete, 8-reserving hole, 9-gutter, 10-purifies header tank, 11-hygrophyte, 12-Climbing Plant, 13-shrub greenbelt.
The specific embodiment
Excavation of foundation pit and backfilling process requirement, mortar mixing construction technical requirement and the requirement of Reinforced Concrete Retaining Walls casting craft etc., be not repeated in present embodiment, and emphasis is set forth the embodiment that the utility model relates to structure.
