Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building design, in particular to a block mechanical sand barrier for wind-proof and sand-fixing. Background Art
[0002] Wind and sand control, sand prevention and control are important public welfare activities related to human survival and development. Sand barriers refer to barriers set up on the surface of flowing sand using solid materials to control the movement of wind and sand and prevent wind and sand hazards. Sand barriers are divided into two categories: mechanical sand barriers and plant sand barriers. Mechanical sand barriers refer to barriers laid or buried on the surface of flowing sand using materials such as plants, clay, gravel and geotextiles.
[0003] For a long time, my country has adopted the more common mechanical sand barrier, which is the grass grid sand barrier. Although the sand control effect is good, it also has the following disadvantages:
[0004] 1. The grass grid is easily damaged and needs to be replanted after 2 to 3 years, which invisibly increases the maintenance cost.
[0005] 2. As a scattered material, the grass grid is inconvenient to transport over long distances or in reverse, and the cost is high. Whether it is a hand-planting process or a foot-treading process, it is basically constructed manually, and the project efficiency is low. As the labor cost increases, the cost of the grass grid increases.
[0006] 3. Materials such as reeds and straw can also be used as feed, papermaking raw materials, building materials, etc., and have relatively high market prices. The source of the materials often does not match the location of the sand control project, and the availability of the materials is poor.
[0007] 4. When the straw grids rot and are damaged, biochar leaks out, increasing greenhouse gas emissions. Utility Model Content
[0008] The utility model aims to provide a mechanical sand barrier made of blocks for preventing wind and fixing sand, so as to solve the problems raised in the above-mentioned background technology.
[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mechanical sand barrier with blocks for windbreak and sand fixation, comprising a first sand barrier body and a second sand barrier body, and also comprising:
[0010] A plurality of groups of support blocks are fixed on the top of the second sand barrier body, the inner wall of the support block is rotatably provided with a connection block, the outer side of the connection block is rotatably provided with an adjustment block, the inner wall of the adjustment block is rotatably provided with a connection plate, the bottom of the connection plate is fixed with a clamping rod, and the inner wall of the first sand barrier body is provided with two groups of clamping holes;
[0011] A fixing tube is fixed to the inner wall of the first sand barrier body, a first spring is fixed to the inner wall of the fixing tube, a fixing column is fixed to one end of the first spring, and a connecting hole is opened on the inner wall of the second sand barrier body.
[0012] Preferably, a connecting rod is fixed to one side of the adjusting block, and a handle is fixed to one end of the connecting rod.
[0013] Preferably, a plurality of second springs are fixed to the outer side of the fixing column, and a limiting pin is fixed to one end of the second spring.
[0014] Preferably, a first mounting block is fixed to one side of the second sand barrier body, and a buckle is fixed to one side of the first mounting block.
[0015] Preferably, a second mounting block is fixed to one side of the first sand barrier body, and a limiting rod is rotated on one side of the second mounting block.
[0016] Preferably, a shift block is rotatably disposed on the outer side of the limiting rod, and a locking rod is rotatably disposed on the outer side of the shift block.
[0017] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0018] This utility model transforms industrial solid waste into a mechanical sand barrier for windbreak and sand fixation, and is innovatively used in ecological engineering, which can realize waste utilization and promote circular economy and green development. The grass grid is used as a scattering material, which has high cost, low efficiency, large loss, and environmental pollution during the process of loading and shortening. However, the size of this patent is regular, easy to transport, simple construction, labor cost saving, and high laying efficiency. During the decay and damage of the grass grid, greenhouse gas emissions will be generated, and solid waste pollution and landscape pollution will be caused to the original ecological environment of the sand. However, this device will not generate greenhouse gas emissions, leaving dust to dust and soil to soil, and will not affect the original landscape of the sand. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Working principle: First, use lime powder or rope to lay out the lines on the windward sand control surface, and divide it into 120cm×120cm squares. Dig a trench 8cm wide and 5cm deep on the sand along the line to form a trench. Hold the plate-shaped first sand barrier body 1 and the second sand barrier body 2 with both hands and plant them vertically into the trench.
