Description

A supplementary construction tool for setting up grass square sand barrier

Technical Field

The utility model relates to the technical field of environmental management equipment and facilities, in particular to an auxiliary construction tool for arranging a grass square sand barrier.

Background

Grass grid sand barriers are commonly called as wind walls by people in sand areas, and are formed by binding grass planting materials such as wheat straws, rice straws, reeds and the like on a flowing dune to form a plurality of grid wind blocking walls so as to weaken the erosion of wind power. The grass grid sand barrier has the main functions of increasing the roughness of the surface of the sand and reducing wind power, so that loose sand grains can be carried away without force. After the grass square sand barrier is arranged, the effect of intercepting rainfall is achieved, and particularly for snowfall in winter, the grass square sand barrier can be controlled to be in place and not blown away by wind. Therefore, the water content of the sand layer is improved, the water content of the sand layer with the thickness of 2 meters is increased from 1 percent to more than 3 percent to 4 percent, and the grass square lattice sand barrier can fix the quicksand and improve the moisture condition of sand dunes, so the sand plant growth is protected.

When the grass square sand barrier is arranged, firstly, construction square lines are marked on a sand dune, and the sand barrier is required to be perpendicular to the local main wind direction. And then, transversely placing the uniformly and tidily trimmed grass planting on the grid line, pressing the grass planting middle by using a spade or other tools, forcibly inserting the grass planting middle into the sand layer for about 15cm, enabling the two ends of the grass planting to be upwards tilted and upright on the sand surface, and enabling the height of the grass planting to be exposed out of the ground to be about 20-25 cm. And burying the root base of the grass grid sand barrier with sand by using a tool so as to enable the root base to be firm.

However, when the grass grid sand barrier is arranged, because no special auxiliary tool is provided, the process of pressing the wheat straw into the sand layer by using a spade or the like is not easy to operate, and time and labor are wasted. Therefore, an auxiliary construction tool for arranging the grass square sand barrier, which has the advantages of ingenious structure, easiness in operation and convenience in construction of the grass square sand barrier, is urgently needed in the prior art.
