Problems solved by technology

[0005] The purpose of the present invention is to propose an ecological geogrid for slope protection and its construction method for the existing geogrid without considering its ecological effect, so as to solve the problem of poor plant living environment and greening problems in the existing slope protection. For problems with unsatisfactory effects, it can not only strengthen the slope, but also achieve long-term greening, and realize the dual effects of engineering reinforcement and greening of the slope

Embodiment 1

[0031] Such as figure 1 Shown, a kind of ecological geogrid for slope protection is characterized in that:

[0032] It mainly includes geogrid protective net, anchoring structure, nutrient soil 5, plant seeds 6, and several water pipes 8.

[0033] The geogrid protective net is composed of criss-cross tubular geogrids 2, fixed and laid above the surface of the slope 1 through an anchor structure. The anchoring structure includes several soil nails. There are several soil nail fixing points 4 on the tubular geogrid 2 . These soil nails fix the geogrid protection net on the side slope 1.

[0034] Such as figure 2 As shown, the tubular geogrid 2 is a criss-cross geogrid, and its interior is hollow. The interior of the tubular geogrid 2 (that is, the interior of the hollow tube) accommodates nutrient soil 5 , plant seeds 6 and water delivery pipes 8 .

[0035] The water pipe 8 is located at the bottom of the inner cavity of the tubular geogrid 2 and is fixed to the inner wal...

Embodiment 2

[0041] The present embodiment is directed to the construction method of an ecological geogrid for slope protection described in Embodiment 1, which is characterized in that it includes the following technical steps:

[0042] 1) Produce the tubular geogrid in the factory, that is, the tubular geogrid mesh. There are reserved holes in the middle of the geogrid, which forms a criss-cross hollow pipeline network. In the holes, there are water pipes and geogrids fixed together, and the water pipes form a criss-cross water pipeline network system. The specific mesh of the geogrid can also be arranged in rhombus or other shapes.

[0043] 2) Prepare the nutrient soil, which contains plant seeds and fertilizers needed for plant growth.

[0044] 3) Fill the nutrient soil into the holes inside the geogrid.

[0045] 4) Transport the ecological geogrid network with water pipes and nutrient soil to the top of the slope.

[0046] 5) Spread the geogrid on the slope surface from top to bott...

Abstract

The invention discloses an ecological geogrid for slope protection. The ecological geogrid for slope protection is composed of a geogrid protection net, an anchoring structure, nutrient soil, plant seeds, a water conveying pipe and the like, wherein the geogrid protection net is fixedly laid on the surface of a slope through a plurality of soil nails; the nutrient soil fills tubular geogrid holes,and the plant seeds are put in the nutrient soil; rainwater on the slope can permeate into the nutrient soil in the tubular geogrid holes via meshes of woven fabric, the plant seeds in the nutrient soil absorb water to sprout and grow, and a green ecological slope is formed; and when rainwater is insufficient, water can be supplied to the nutrient soil at regular time intervals through the waterconveying pipe so that sufficient water can be ensured for plant growth. The invention further discloses a construction method of the ecological geogrid slope. The stability and afforesting effect ofthe slope are improved, the dual effects of engineering protection and ecological protection are achieved, neither water nor nutrient component is lost, the resource utilization is maximized, and long-term stable growth conditions are provided for vegetation.

Description

technical field [0001] The invention belongs to the technical field of rock and soil slope protection, in particular to an ecological geotechnical grid for slope protection and a construction method thereof. Background technique [0002] With the development of my country's infrastructure construction, a large number of roads and railways have been constructed, and the excavation of earth-rock slopes has destroyed the original vegetation coverage, resulting in the exposure of a large amount of soil and rock slopes, resulting in serious soil erosion and rockfall, etc. It also caused damage to the ecological environment while causing potential safety hazards. In particular, the high and steep rocky slopes left over from engineering construction lack the soil conditions, nutrient conditions and water conditions for plant growth, which will result in low plant survival rates, and there are few technologies that can be used for comprehensive protection and greening. Conventional ...
