Abstract

The invention relates to a reinforced ecological concrete revetment and belongs to the field of revetment engineering, geotechnical engineering and ecological rehabilitation projects. The reinforced ecological concrete revetment comprises a revetment top, a revetment surface and a revetment toe, wherein the revetment top is provided with a concrete column prefabricated hook pile; the revetment surface comprises nutritional geotechnical cloth, lower layer ecological concrete, a geogrid, upper layer ecological concrete, artificial casing soil and environment protecting plants in sequence from bottom to top along a direction vertical to the revetment surface; the nutritional geotechnical cloth is hung on the concrete column prefabricated hook pile; the revetment toe is dug to form a groove; filler is paved in the groove and is compacted. According to the reinforced ecological concrete revetment disclosed by the invention, the ecological concrete and the geogrid made of a flexible material are alternately compressed, and are combined into a whole, so that the crack resistance and the settling resistance of the revetment engineering are enhanced; the nutritional geotechnical cloth not only has a reverse filtering function but also is in favor of the ecological protection on roots and prevention on water and soil loss, and therefore the erosion resistance and the stability of the revetment engineering are greatly enhanced.

Description

A kind of reinforcement eco-concrete bank protection and construction method thereof
(1) technical field
The invention belongs to slope protection works, geotechnics, Ecological Restoration Project field, particularly a kind of Fill Reinforced With Geogrids eco-concrete bank protection and construction method thereof.
(2) background technology
Slope protection works mainly prevents the inclined plane of road, river, dam and reservoir from being washed away, and slope protection works is divided into traditional bank engineering and ecological revetment engineering.
Traditional bank project post-evaluation ability is strong, only considers the mechanical stability of bank protection in design, and its appearance design is comparatively dull and stiff, inharmonious with surrounding landscape, destroys the balance of the ecosystem, is unfavorable for protection and the water and soil conservation of ecological environment.In order to overcome the defect of traditional bank, ecological revetment engineering is arisen at the historic moment.Relative to traditional bank engineering, ecological revetment engineering has good plants raw function, and reducing prevention soil erosion, desertification of land and bio-diversity has positive effect.
But ecological revetment engineering still inevitably needs to use concrete, because concrete material self exists some defects, as poor in impact resistance, be easy to shrinkage cracking etc., especially concrete material is easy to the defect of shrinkage cracking, makes the performances such as it is impervious, freeze proof, resist chemical, reinforcement anticorrosion receive very large impact.The main cause that crack is concrete structure supporting capacity, durability reduces, can cause the domatic sinking of slope protection works, have a strong impact on engineering outward appearance, using function and application life.
Geo-grid is a kind of important geosynthetics, is commonly used for the muscle material of earth structure or the muscle material etc. of composite material.Relative to concrete, geo-grid is a kind of flexible material, and the stress distribution of muscle material both sides can be made even, not only plays " indirect strengthening " effect, and can the pliability of reinforcing material.
(3) summary of the invention
The technical problem to be solved in the present invention is: provide a kind of reinforcement eco-concrete bank protection, and solution slope protection works cracking resistance is poor, the problem of anti-settling poor performance.
Technical scheme of the present invention is as follows:
A kind of reinforcement eco-concrete bank protection, comprises top, slope, domatic and toe, it is characterized in that: top, described slope is provided with the preset metal hook stake of concrete column; Described domatic edge comprises nutrition geotextiles, lower floor's eco-concrete, geo-grid, upper strata eco-concrete, artificial earthing and environment protecting plant from bottom to top successively perpendicular to domatic direction, and described nutrition geotextiles is hung in the stake of concrete column prefabricated metal hook; Described toe has dug groove, lays filler and compress in groove.
Described concrete column prefabricated metal hook stake adopts piling or pre-buried mode to be driven underground, and the length of the preset metal hook stake of concrete column is 1.0 ~ 1.5m.
Between described nutrition geotextiles, overlapping the slot merging staple is fixed; The two ends of nutrition geotextiles adopt anchor pole to fix, and rockbolt installation density and length determine as calculated afterwards according to the actual conditions of local soil; The weight of nutrition geotextiles is at 300g/m 2above.
Described geo-grid hole lattice are of a size of 30-120mm, and intensity is at more than 30N/m.
Described lower floor eco-concrete, geo-grid and upper strata eco-concrete three gross thickness are 10-20cm.
Described filler is lattice guest gabion or free stone masonry.
As preferably, in described artificial earthing, also comprise polymer aggregate.
The present invention also provides a kind of construction method of reinforcement eco-concrete bank protection, comprises the steps:
1) slope control: the obstruction hindered constructing highway to be onstructed or river course domatic, foreign material are cleaned out;
2) by domatic compacting, the stake of concrete column prefabricated metal hook is driven underground by employing piling, pre-buried mode;
3) nutrition geotextiles is hung in the stake of concrete column prefabricated metal hook, and along domatic expansion;
4) in the groove of toe, lay filler compress, prevent slope protection works from gliding;
5) cast-in-placely in nutrition geotextiles a layer eco-concrete is poured down, after lower floor's eco-concrete initial set, along domatic laying geo-grid, cast-in-place note upper strata eco-concrete in geo-grid;
6) after the initial set of upper strata eco-concrete, perfusion containing the mud maintenance of grass-seed, then on eco-concrete top layer artificial earthing 2-4cm;
7) plant maintenance: after having laid, will carry out water seasoning in time, guarantees the wettability that whole side slope surface keeps certain.
Compared with prior art, geo-grid of the present invention is located between upper and lower two-layer eco-concrete, and eco-concrete and flexible material geo-grid replace pressing, and the two is integrated, and enhances cracking resistance and the anti-settling performance of slope protection works.Nutrition geotextiles water permeability used and gas permeability all good, not only there is anti-filter function, and include nutrient matrix, be conducive to plant root growth and deeply prick in rock aspect, thus the effect reaching root system ecological protection, prevent erosion.Pbz polymer granule in artificial earthing used, is conducive to plant growth, strengthens the scour resistance of bank protection.Toe lays filler, ensure that the stability of slope protection works better.
