Embodiment Construction

[0030] In order to further understand the content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are given below with reference to the accompanying drawings. It should be noted that this embodiment is descriptive, not restrictive, and cannot thereby limit the protection scope of the present invention.

[0031] An ecological protection structure for a rocky cutting slope, comprising an anchoring layer, a geogrid layer, a three-dimensional mesh layer and a sprayed layer fixed sequentially from the lower layer to the top layer, wherein the anchoring layer is anchored and fixed in the rocky cutting slope 1, And the top of the anchoring layer is fixedly connected with the geogrid layer; the inside of the geogrid layer is filled with planting soil, and the top of the geogrid layer is fixedly laid with a three-dimensional mesh layer; the mesh surface of the three-dimensional mesh layer is sprayed with a spray coating....

Abstract

The invention relates to a rock cutting slope ecological protection structure and a construction method thereof. The rock cutting slope ecological protection structure comprises an anchoring layer, ageogrid layer, a three-dimensional net layer and a spraying layer which are fixedly arranged in sequence from a lower layer to a top layer, wherein the anchoring layer is anchored and fixed in the rock cutting slope, and the top of the anchoring layer is fixedly connected with the geogrid layer. The structure is characterized by filling planting soil in the geogrid layer, and fixedly laying the three-dimensional net layer on the top of the geogrid layer; and the spraying layer is sprayed on the net surface of the three-dimensional net layer. The construction method of the rock cutting slope ecological protection structure mainly comprises the following steps: measurement lofting -> slope surface finishing-> anchor rod drilling installation -> steel casing installation and internal pouring-> geogrid laying -> three-dimensional net laying -> (matrix layer, seed layer and microorganism layer) spraying construction -> maintenance. The scheme can effectively solve the problem of water andsoil loss caused by rainwater washing of the planting soil in an area with large annual average precipitation, and manual reseeding or soil supplement construction is not needed, so that the burden ofmanual maintenance is reduced.

Description

technical field [0001] The invention relates to the technical field of slope construction, in particular to a rock cutting slope ecological protection structure and a construction method thereof. Background technique [0002] Rocky slope ecological restoration technology is a new technology for slope protection. It is to construct anchor bolts on stable rocky slopes, spread galvanized steel wire mesh behind soil, and spray grass and shrubs to the sides. The slope is greened, and the plants rely on the "basic layer" to grow and develop, forming a comprehensive slope protection system slope protection technology. After the excavation slope is formed, by planting plants, the interaction between plants and rock and soil (root system anchorage) is used to protect and reinforce the surface of the slope, so that it can not only meet the requirements for the stability of the slope surface, but also can A slope protection method to restore the destroyed natural ecological environmen...
