Abstract

The utility model provides a nature-imitated ecological protection structure of water banks for rivers, lakes and channels, which belongs to the type of ecological environment and mainly comprises a vertical imitated stump, a high strength geogrid net for imitating tree fibrous roots, inversed filter non-woven cloth used for preventing water bank soils from being washed away with streams and a gravel ecological protection layer, wherein the vertical imitated stump is a reinforced concrete hook pile which has the square section or the round section, is arranged in the ground of the water banks in a piling mode and is made of C-20 to C-30 concrete. The gravel ecological protection layer can avoid water erosion, protect the water banks to be stable and simultaneously constitute an aquatic plant and animal growth and habitat space, and adopt gravels which have the grain diameter of 40mm or so and are filled between a geogrid and the non-woven cloth. Sand-free ecological concrete with the grain diameter of 20mm to 30mm are adopted to seal the top above the water gravel ecological protection layer. The nature-imitated ecological protection structure utilizes concrete materials and geotechnical synthetic materials to imitate tree roots of natural water banks, can protect the water banks to be stable, and has the practical applicability of simple and fast construction, low manufacturing cost, and ecological restoration.

Description

Lake, river ditch water in a canal bank is intended the natural, ecological safeguard structure

Technical field

The utility model relates to the ecological environment class, and lake, particularly a kind of river ditch water in a canal bank is intended the natural, ecological safeguard structure, refers to a kind of simple and easy, economic, ecological lake, river ditch water in a canal bank plan natural, ecological safeguard structure especially.

Background technology

The water bank of middle-size and small-size river, lake and reservoir, escape canal etc. always receives destructions such as stormy waves washes away, freeze thawing landslide, must adopt engineering method to protect.Should ensure water bank protection safety, build and improve the basic function of the water bank ecosystem again, water body oneself detergent power is kept in the habitat of protection bank plant growth environment and animal, builds natural, ecological and charming water bank view.

Traditional means of defence adopts modes such as stone-laying, concrete basically both at home and abroad, has greatly developed the method that adopts concrete component to protect in recent years; But water bank for distribute middle-size and small-size widely river, lake and reservoir, escape canal etc.; Not only cost is higher for said method, inconvenience construction, mainly also influences and has destroyed the water bank ecosystem, causes water plant to be difficult to growth; Organism in water loses and perches, rests, multiplies ground, and aquatic bird does not have looks for food ground.The domestic middle and small river regulation of carrying out energetically at present, the system reform of lake aquatic attitude, the pollution of waterhead control of irrigated area, paddy field etc. are needed badly a kind of simple and easy, economic, ecological water bank safeguard structure are provided.

The utility model content

The utility model is fixed and is protected bank stability to gain enlightenment from the tree root of water bank, adopts concrete and the simulation natural water bank tree root of geotechnological composite structure, protection water bank stable, and it is ecological to recover its water bank, specifically comprises:

Steel concrete along water bank length is arranged is linked up with stake; Its simulation vertical stub; Insert underground with piling or pre-buried mode along the water bank; It is square, polygon or circular structure for adopting C20～C30 concrete to process the cross section, and the length of stake is definite according to the height of protection needs, is specially 1.0-2.0m;

The pre-buried earth work grille net reinforcing bar that is used for the simulation trees system of fibrous root of hook in the top of steel concrete hook stake is linked up with;

Be hooked on the high-strength earth work grille net in the stake of steel concrete hook, it is the net structure of the simulation trees system of fibrous root, and the hole lattice of GSZ are of a size of 30-40mm, and intensity is 30N/m ²More than;

The anti-sealing bank soil that is used for being used with high-intensity earth work grille net is used nonwoven with the anti-filter that current run off; Launch and be laid on the furrow bank of bottom of trench and relative land side, rubble ecological protection layer adopts rubble to be filled into GSZ and instead to filter with in the middle of the nonwoven;

Constitute that the space is perched in the aquatic animals and plants growth, to have a protection water bank stable and play the protection against erosion effect, be filled into earth work grille net and the middle rubble ecological protection layer structure of nonwoven, its ballast grain sizes that adopts is not more than 40mm;

Above the rubble ecological protection layer on the water, adopting particle diameter is the no sand eco-concrete sealing-top structure of 20-30mm, and earthing in the above, the plantation emergent aquactic plant.

Application process:

1. along water bank water front, every interval 1.0-1.5m adopts piling or pre-buried mode, and the water bank is squeezed in the stake of steel concrete hook, exposes highly generally to exceed 200-500mm than the water surface.

2. in the inboard ditching of steel concrete hook stake, its width is 0.5m, and the degree of depth is confirmed as 0.5-1.0m according to requirement of shelter.

3. GSZ is hung over steel concrete and link up with on the preset reinforcing bar hook of stake, and be U type expansion layout along the degree of depth and the cross sectional shape of Tu Gou.

4. nonwoven is launched and is laid on the furrow bank of bottom of trench and relative land side.

5. crushed stone is filled up in the U type groove of GSZ formation.

6. use the non-fine concrete capping rubble top of particle diameter, cover anthropogenic soil but solidify the back as 20-30mm, and emergent aquactic plant such as plantation reed.

The advantage of the utility model is: the utility model is fixed and is protected bank stability to gain enlightenment from the tree root of water bank; Adopt concrete material, the simulation natural water bank tree root of geosynthetics, have the stable of protection water bank, it is simple and direct to construct; Cheap, the practicality of ecology recovering.
