Description

Device for sand barrier construction of dune topography Technical Field The utility model relates to the technical field of wind prevention and sand fixation, in particular to a device for sand barrier construction of a sand hill topography. Background The sand fixation forestation for many years makes desertification control of China obtain good situations of continuous reduction and function enhancement, and continuous practice and summarization prove that sand control is necessary to fix sand first, grass square has the functions of increasing the surface roughness and reducing the near-surface wind speed, and simultaneously has the functions of creating stable sand surface environment for soil crust development, sandy plant seed implantation and seedling planting. The sand control practice for many years proves that grass square grids are one of the most effective methods for fixing the quicksand, but the terrains of the sand are complex and various, sand dunes are rough and have larger gradient change, different square grids are selected according to regional wind conditions and terrains, the square grids have specifications of 1.5mx1.5m1.5m1 m, 1 mx1 m and the like, most of the sand areas in the existing laying mode still adopt the traditional manual laying mode, specifically, wheat straw is pressed into the sand from the middle part by a blunt shovel manually, the depth of the grass square grids inserted into the sand is 15-25cm, the height of the exposed sand surface is 15-25cm, the wind speed of the ground can be reduced by 40 times by the grass square grids, and the grass square grids can be rebindled after 3-4 years of wheat straw is rotten. The organic matters are deposited on the surface of the sand layer to form a layer of sand crust, the sand layer is finally naturally formed into a protective film on the surface layer of the sand, and the quicksand can be fixed, but because the desert working environment is severe, the work load of manually paving grass square sand barriers is large, and the obstacles of topography factors (the gradient of partial sand dunes is more than 10 degrees) are added, so that the planting difficulty is increased, the paving efficiency is reduced, and a plurality of people are required to cooperatively carry out.
