Problems solved by technology

With the development of industries such as engineering construction and mining, a large number of tall and steep rock slopes that are difficult to restore have been formed all over the country. Due to their large slope and high height, it is difficult for plant growth substrates to attach to the slope under the action of gravity. On the slope, the sprayed soil is prone to secondary damage such as loss and slippage, which in turn restricts the growth of plants and affects the ecological restoration of the slope.

Embodiment Construction

[0021] In conjunction with the accompanying drawings, the present invention will be further described through implementation cases.

[0022] A construction of an effective soil layer for an ecological protection structure of a tall and steep rock slope, comprising a main anchor 1, an auxiliary anchor 2, a geocell 4, a galvanized machine-woven barbed wire 5, and a constructed soil layer 6. The specific layout steps are as follows:

[0023] ① Carry out slope cleaning measures such as removal of dangerous rocks, removal of gravel, floating soil and weeds, and filling of low-lying areas on the rocky slope 3, so as to ensure that the slope after treatment is flat and even, and the up and down slopes are basically the same.

[0024] ②Drill and grout the main anchor 1 on the top of the slope at a distance of 50cm and on the slope at a distance of 2m×2m, and fix the auxiliary anchor 2 on the slope at a distance of 50cm×50cm in the same way.

[0025] ③Lay the geocell 4 on the cleaned ...

Abstract

The invention relates to the field of environmental protection, and discloses an establishing method of an effective soil layer of an ecological protection structure of a high steep rock slope. Aftera cleaned slope surface is reinforced through threaded anchor rods, geocells and galvanized machine woven iron gauze, the effective soil layer needed by ecological slope protection is established in the manner that wet process soil spraying and crane soil filling are combined. By means of the establishing method of the effective soil layer, the thickness of the effective soil layer established onthe slope surface of the high steep rock slope is not smaller than 15 cm, the problem that soil with the thickness larger than 10 cm is hardly established on the slope surface of the high steep rock slope due to the gravity effect is effectively solved, construction is easy and convenient, the effect is remarkable, and a good soil environment is provided for the growth of plants.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a method for constructing an effective soil layer of an ecological protection structure for a tall and steep rocky slope, which is mainly applicable to ecological restoration projects for steep rocky slopes such as road slopes, mines, and quarries. Effective soil layer construction. Background technique [0002] Ecological slope protection is a slope restoration method that combines plants or plants with engineering. Compared with traditional slope protection, it not only plays the role of water and soil conservation, but also has the ecological effects of purifying air, adjusting microclimate, reducing noise, and being beautiful and environmentally friendly. The ability gradually increases with the vegetation growth years, and can gradually restore the ecological landscape damaged by construction and other reasons. With the development of industries such as engineering c...
