Soil covering and grass planting construction method for plateau alpine region

Abstract

The invention discloses a soil covering and grass planting construction method for a plateau alpine region. The soil covering and grass planting construction method comprises the following steps: S1, soil matrix investigation; S2, preparation of a soil matrix layer; S3, stone crushing treatment; S4, building of drainage ditches; S5, muck improvement; S6, application of an organic fertilizer; S7, sowing and post-processing; and S8, construction and mounting of enclosing fences. The method is suitable for the technical field of soil covering and grass planting. A mine soil aggregate structure is rebuilt, the soil matrix layer of an open pit coal mine in the plateau alpine region is rapidly improved, the ecological restoration benefit is improved, a mining area ecological system is constructed, the greening window period of the plateau alpine region can be shortened, the working procedure is simplified, the efficiency is improved, the problem that the grass planting window period is short is solved in the aspect of time, the soil covering and grass planting technical process and standard of the plateau alpine region are formulated, the working procedures are defined, and funds are saved.

Description

technical field [0001] The invention belongs to the technical field of covering soil and planting grass, in particular to a construction method for covering soil and planting grass in plateau alpine regions. Background technique [0002] Covering soil and planting grass is a common ecological environment restoration method, which is often used in mine environmental restoration. After the terrain reshaping is completed, the mine regreening work will be completed on the mine slag hill slope plane, slag hill plane, slag hill slope, road living area and other working surfaces [0003] However, there are following defects in the existing method of covering soil and planting grass: [0004] 1. In the plateau alpine region, it has a unique ecosystem, high altitude, thin air, cold climate, arid, difficult site conditions, and a fragile ecological environment. After years of open-pit mining, the soil layer has been stripped on a large scale, which has a negative impact on the entire...

AI Technical Summary

Problems solved by technology

Existing ecological restoration methods cannot meet the needs of creating a growth environment for grass seeds

[0005] 2. The seasonal freeze-thaw period in the plateau alpine region is generally at the end of April, and the local soil source is frozen during the construction period. The traditional method of excavating, screening, covering soil and planting grass cannot complete the task

[0006] 3. In plateau and alpine regions, the technical process and standards of planting grass are inconsistent, and the process is not clear, resulting in waste of personnel, machinery and materials
