Construction method and structure of wind-prevention and sand fixation brick array

Abstract

The invention discloses a construction method and structure of a wind-prevention and sand fixation brick array. According to the annul prevailing wind direction and the maximal wind speed of a desert in the area to be subjected to wind prevention and sand fixation, cuboid clay bricks taking clay as a main material are made, the clay content of each brick is not lower than 70% of the total size of the brick, a plurality of vertical through holes are formed in each brick along a height direction, the clay bricks are paved on the surface of a sand field in a staggered configuration manner to form a multi-row multi-line brick array, the length direction of each brick is rightly opposite to the annular prevailing wind direction of the area, the maximal distance of two adjacent bricks is not more than 7 times the length of each brick, the sum of the ground contact area of the bricks is not more than 50% of the area of the covered sand field, and the minimal value of the width of the brick array is 1.2 times more than the maximal wind speed. According to the construction method and structure disclosed by the invention, by means of paving the sand field with the clay brick array, an effective wind prevention and sand fixation effect is achieved, the local ecological and soil environment in a desert area can be further improved, and a role of promoting the increase of the natural growth of plants in the desert region is played.

Description

Technical field [0001] The invention relates to the technical field of a wind-proof and sand-fixing construction method, in particular to a construction method and structure of a wind-proof and sand-fixing brick array. Background technique In traditional desert greening projects, desert wind-proof and sand-fixing methods such as grass grids and gauze grids are often used. These methods can indeed play a role in wind-proofing and sand-fixing, but these methods can only play a physical wind-proof role and do not change the desert soil. It is not easy to retain water and fertilizer, so it is difficult to promote the natural invasion of vegetation. Some people use clay to build windbreak dams, or use soil mixed fertilizers and plant seeds to make improved soil conducive to vegetation growth, and cover the sandy land. It can not only play the role of windproof and sand fixation, but also improve the growth conditions of vegetation, thereby increasing natural vegetation. However,...

However, these methods require a large amount of soil, and small-area bedding is possible, but the transportation and construction costs of large-scale bedding are very high, and, because the desert is dry, loose soil is easily blown away by the wind
