An x-shaped windshield wall and its construction method

Abstract

An X-shaped wind-retaining wall and its construction method, wherein the left wind-accumulating wall (3), the right wind-accumulating wall (4), and the fixed column (9) are connected together through an energy-dissipating sand-blocking net. The construction method is: The left end of energy sand-blocking net is connected to the left wind-gathering wall (3), its right-hand end is connected to the right wind-gathering wall (4), and the middle is connected to the fixed column (9); the right guide wall (2), the right wind-gathering wall ( 4), right 1 divider wall (7) is a whole; left 2 divider walls (6), right 2 divider walls (8) are a whole. The strong wind is led to the energy dissipation area by the left guide wall (1) and the right guide wall (2), and then the strong wind is led to the energy dissipation and sand-blocking net by the left wind gathering wall (3) and the right wind gathering wall (4). Lower and blow to the next energy-dissipating sand-blocking net until the last energy-dissipating sand-blocking net, the airflow blows to the junction of the left 2 diversion wall (6) and the right 2 diversion wall (8), and is divided into two, and flows to the left and right sides. On the side, the air transmission corridor is formed by the diversion wall, which is exported to the main protection area.

Description

technical field [0001] The invention relates to windproof soil improvement technology, in particular to X-shaped windshield wall technology. Background technique [0002] With the increase of the earth's population and the continuous growth of the economy, the pressure on the ecological environment is increasing day by day. The current ecological environment has been severely damaged, especially in Northwest China. To prevent land desertification, protect farmland, pastures, traffic and residential areas from the harm of wind and sand flow and sand dunes, it is necessary to take necessary anti-wind and sand measures . Patent: 201710950537.8 introduces a Gobi windbreak wall and its construction technology, which is mainly used in the Gobi area to intercept wind and sand. Although this device can reduce the erosion of wind and sand to a certain extent, it can slow down the wind speed on the front side of the protected area, but the northwest The wind direction in the area is...

Patent: 201710950537.8 introduces a Gobi windbreak wall and its construction technology, which is mainly used in the Gobi area to intercept wind and sand. Although this device can reduce the erosion of wind and sand to a certain extent, it can slow down the wind speed on the front side of the protected area, but the northwest The wind direction in the area is changeable and the wind and sand are relatively large and have a strong impact on buildings. This structure still does not meet the needs of intercepting wind and sand in the northwest region; The impact of the building, and the energy dissipation part of this device only uses a mesh polypropylene non-woven geotextile to reduce the wind speed. Although this device has a certain effect of reducing the wind speed, because the wind and sand can still reach the protection area through the mesh, so It is not applicable to the aspect of preventing wind and sand erosion in Northwest China

Patent: 201810410540.5 introduces a method for reducing desert flow by photovoltaic arrangement of windshield walls, which is mainly used in deserts, Gobi, and sandy areas where wind and sand are raging and lower than the vastness. This device uses the arrangement and layout of photovoltaic panels and windshield vegetation Although this device has a certain wind-shielding effect, the device is relatively complicated and requires the mutual protection of photovoltaic panels and wind-shielding vegetation to work, but the vegetation growth cycle is relatively short, especially in alpine regions. , and very difficult to survive

Moreover, the vegetation in areas with harsh environments is mostly short and short, which makes it difficult to protect photovoltaic panels, which limits the application of this device and cannot fully meet the requirements of windbreak and sand fixation.
