Greening grid device and construction method of rock slope

Abstract

A greening grid device for a rock slope, comprising a ventilating layer, a fine mesh fixed layer, a sprayed planting base, a grass seed box fixed net layer and a sprayed planting surface layer, which are sequentially fixed and connected by anchors on the upper surface of the rock slope; A cushion block is fixedly installed in the ventilation layer, the bottom surface of the cushion block is fixedly connected with the slope surface of the rock slope, and the top surface of the cushion block is fixedly supported on the bottom surface of the fine mesh fixed layer; the fine mesh fixed layer includes a fixed mesh Net, the fixed fine net and the grass seed box fixed net layer sandwich the fixed spray planting base; the grass seed box fixed net layer includes the grass seed box fixed net, and the steel wire cross connections inside the grass seed box fixed net are all fixed There is a grass seed box; the upper surface of the fixed mesh layer of the grass seed box is sprayed with a spray-planting surface layer. The greening grid device and its construction method use the characteristics of the grass seed box to the vegetation concrete construction by making the grass seed box fixed net with the grass seed box, and solve the germination rate and survival rate of the plant seeds after the spraying construction is completed. Low problem.

Description

technical field [0001] The invention belongs to the technical field of rock slope engineering, in particular to a greening grid device for rock slopes and a construction method thereof. Background technique [0002] At present, vegetation concrete technology is mostly used for protection and greening of rock slopes. This technology uses specific concrete formula and mixed green seed formula. The core of this technology is the extensive application of cement, which can enhance the strength of slope protection and anti-scouring ability, and quickly create plants. growth environment. The vegetation concrete ecological protection technology can not only better solve the problems of rock slope protection and rapid greening, but also under the joint action of shrub vegetation and substrate, the erosion resistance of the substrate will be further enhanced. To ensure the rapid prototyping and ecological stability of vegetation, this technology uses cement as the binder, plus specia...

AI Technical Summary

Problems solved by technology

The vertical slope greening device and method for fixing vegetation concrete with cement blanket boards provided by the present invention can solve the problems of water and fertilizer loss, block falling off or green belts caused by weathering of rock and soil surface in the traditional method in the vegetation concrete of high and steep rock slopes. Falling off, steel wire mesh is easy to rust and affects soil pH, plastic is easy to age, and maintenance is difficult in the later stage.
