Abstract
The utility model relates to a dyke adopting a sand filling pipe bag ecological slope protection structure, which comprises a dyke base body with a slope surface and a slope protection surface structure, wherein the slope protection surface structure comprises non-woven fabrics and a plurality of sand filling pipe bags, the sand filling pipe bags are formed by filling sand into woven fabric pipe bags with the diameter being 0.5m and the length being 8m, the non-woven fabrics is paved on the slope surface of the dyke base body, a plurality of sand filling bags are in transverse and vertical arrangement according to the set distance and are fixed on the non-woven fabrics and the slope surface to be circulated into a plurality of rectangular base soil pools, a soil slope layer is arranged in each rectangular base soil pool and is positioned on the non-woven fabrics, plants grow on soil layers, and a stone masonry tooth wall is arranged at the slope foot and is butted against the sand filling bag transversely arranged at the lowest part of the dyke slope surface. The utility model solves the problems of easy collapse of the existing dyke slope surfaces, slope protection body falling and the like through rain flushing, the dyke flood fighting capability is improved, the service life of the dyke is prolonged, and in addition, the dyke has little investment and fast takes effect. Because plants such as grass and the like are planted on the slope surfaces, the dyke is favorable for improving the ecological environment.
Description
Technical field
The utility model relates to a kind of dykes and dams, particularly relates to the water-fast towards dykes and dams of a kind of sandstone charging pipe bag bank protection.
Background technology
The protection of traditional water conservancy engineering dyke side slope mainly is that the employing rigidity is the engineering means, side slope is treated as the soil body that the unstability tendency is arranged that does not have life, utilization slope stability analysis method, by calculating the stable problem of quantitative analysis side slope, adopt engineering measure to carry out consolidation process then, overcome problems such as serious soil erosion that side slope brings and landslide.Because side slope protection is only paid attention in being easy to get and being convenient to accurate mechanical analysis of materials such as concrete, building stones, the embankment slope protection often takes technology such as jackstone, concrete slab, concrete interlock plate, clay blanket, woven mould bag to protect.There is several thousand kilometers dyke line in Liaoning Province, though carried out the reinforcement of heightening and thickening or other method in the application engineering measure of part dykes and dams dangerous section, but still have quite a few dike section to have hidden danger, as earth embankment sandization, degraded seriously by rainwater pouring erosion and wind sand, or because fund input small part dangerous section section slope protection works is not thorough, long-time running cause domaticly subside, the bank protection body comes off etc., even some dike section spent a huge sum of money and carried out repeatedly repairing, but still can not reach the effect of putting things right once and for all.
At present, China also adopts simple biological protection technology to carry out bank protection, but a little less than traditional slope vegetation protection pattern erosion resistibility, opposing flood ability, dyke is subject to destruction.
The utility model content
A kind of dykes and dams that adopt sandstone charging pipe bag ecological slope protection structure comprise having domatic dam foundation body and bank protection face structure; It is characterized in that:
Described bank protection face structure comprises nonwoven and a plurality of sandstone charging pipe bag, and the sandstone charging pipe bag is 0.5m by diameter, and is long for being filled with the sand formation in the woven stringing bag of 8m; Nonwoven is laid on dam foundation body domatic, and a plurality of sandstone charging pipe bags are pressed the horizontal extended spread of setpoint distance, and be fixed on nonwoven and domatic on, surround a plurality of rectangle base Tu Chi; Be positioned on the nonwoven in each rectangle base soil pond, be provided with soil horizon, vegetation is arranged on the soil horizon; The place is provided with key-wall at toe, replaces the sandstone charging pipe bag of the bottom horizontally set of dam slope face.
Advantage of the present utility model:
The utility model has solved that present dykes and dams are domatic problem such as impacted by rainwater easily to subside, the bank protection body comes off, and has improved dykes and dams flood fighting calamity ability and application life, and small investment, instant effect.Owing on domatic soil, plant plants such as grass planting, help improving the ecological environment.

The specific embodiment
A kind of dykes and dams that adopt sandstone charging pipe bag ecological slope protection structure comprise having domatic dam foundation body 1 and bank protection face structure;
Described bank protection face structure comprises nonwoven 2 and a plurality of sandstone charging pipe bag 3, and sandstone charging pipe bag 3 is 0.5m by diameter, and is long for being filled with the sand formation in the woven stringing bag of 8m; Nonwoven 2 be laid on dam foundation body 1 domatic 4 on, a plurality of sandstone charging pipe bags 3 are pressed the horizontal extended spread of setpoint distance.And be fixed on nonwoven 2 and domatic on, surround a plurality of rectangle bases soil pond 5; Be positioned on the nonwoven 2 in each rectangle base soil pond 5, be provided with soil horizon 6, vegetation 7 is arranged on the soil horizon 6, described vegetation 7 is the grass with bank protection function of plantation on soil horizon 6.
Be provided with stone masonry key-wall 8 at the toe place, replace the sandstone charging pipe bag 3 of dam slope face 4 bottom horizontally sets.
The protection crest level exceeds design water level 0.5m, and the sandstone charging pipe bag adopts 200g/m
2Woven cloth is with high-strength P.P. suturing with thread management three roads.Nonwoven adopts and sews up, and 2% degree of being imbued with is reserved in the domatic laying of nonwoven.
The thick 400mm of described basic soil layer, nonwoven 400g/m
