Description

 Wind-proof water storage

 The invention relates to the field of ecological protection, sand prevention and water storage. More specifically, the present invention relates to a method for windproof water storage.

 Background technique

 One of the driving forces of sand damage is wind. Under its action, the impact of sand and sand belongs to the mutual collision between hard objects. The result of this collision is that the sand and dust show uplift, horizontal acceleration and The three cases of re-collision under the slope occur continuously. If the interaction between sand and hardened objects becomes the interaction between hard and soft objects, the three movements of sand and dust will occur less or not. At present, methods such as burying grass grids or planting grasses can make hard sand collide with soft grass, which plays a role in fixing sand.

 The problem with the method of burying grass grids is that grass grids are usually made of hay, and they can only fix sand to a certain extent after they are buried in the sand. The buried grass lattice has no inhibitory effect on the evaporation and leakage of surface water, which is not conducive to the humidification of sandy land.

 Afforestation is an active and effective means for sand prevention, water storage, soil and water conservation, air purification, and ecological protection. However, tree planting and greening in the sandy land is a long-term project. The project has a large human, material, water, and financial investment, a relatively low tree survival rate, and high maintenance costs. It is slower in large-scale desertification areas. Afforestation is a long-term project to protect the environment and benefit humanity.

 Therefore, there is a need for a simple and easy method that can effectively achieve sand prevention and water storage.

 Summary of the invention

 The purpose of the present invention is to provide a method for windproof and water storage, which is used to provide the opportunity for the movement of sand to collide with a hard object and a soft object in order to attach the sand dust to the ground surface and reduce the rising of the sand dust.

According to the method of the present invention, waste plastic ropes and waste plastic bags or waste plastic cloths and membranes with a certain strength and toughness are used to achieve sand fixation and water storage, characterized in that the plastic ropes are braided into a grid and attached to the net. The waste plastic film strip on each side of the grid can swing freely. Buried into the ground is a leak-proof waste plastic bag filled with sand. One end of each of the two waste short plastic ropes is tied to the handle of the buried plastic bag, and one end is connected to the surface grid node, so that the net made of long ropes The grid is fixed to the ground, and the waste plastic film strip is exposed to the machine for producing hard sand and soft plastic. meeting.

 detailed description

 The present invention will be described in more detail below with reference to the drawings.

 According to an embodiment of the present invention, the materials used are waste plastic bags and waste plastic ropes or waste plastic cloths and membranes. The plastic rope used needs some strength. Sort the discarded plastic bags. The leaking plastic bag can be cut into two pieces of plastic film tape between the two handles as shown by the dotted line in Figure 1. The waste plastic film cloth, sheet or plastic bag without handle can be cut out of the semi-circular hole as shown in Figure 2 and retain the tongue to form the handle part. The cut out semi-circular hole has a hole diameter of not less than 3cm, and the arc of the hole is not less than 3cm from the end of the film strip. This arc shape can guarantee the uniform force of the openings and prolong the service life. Put the handle part of the plastic film tape on the longest plastic rope.

The invention is implemented at the site where the method of the invention is implemented with reference to the drawings. First dig a pit and fill the sandy soil into a leak-proof waste plastic bag. 1-0. 3m。 And buried in the plastic bag full of sand into the ground to a certain depth, the depth is preferably 0. 1-0. 3m. A short rope with a preferred length of not less than 1 m is preferably fixed to the handle of the plastic bag in a looped form, and the inner diameter of the looped sleeve is not less than 3 cm. Nearly half the length of the short rope on the handle exposed the ground. Connect two adjacent lanyards buried in the bag. To form a grid of plastic ropes and plastic film strips on the ground surface, use a plastic rope for ligation to form a plastic rope with a film strip and a short rope exposed from the ground into a grid on the ground surface. Each side of the grid is Banded with plastic film, preferably three to five. The shape of the grid is a substantially equilateral polygon, preferably a three-sided, four-sided, or pentagonal shape. 5m。 The length of each side is about 0. 4-1. 5m. For example, FIG. 3 shows a case where the grid is a square grid. As shown in Figure 3, the grid is formed by tying a long plastic rope around a short plastic rope exposed from the ground with a tying rope, and making the center of the grid coincide with the center of the buried bag. In operation, the two long ropes with the film tape and the connected short ropes are plied together, and then looped by a plastic rope for ligation. The inner diameter of the looped sleeve is preferably not less than 3 cm. It can be seen that the grid is formed by looping two long ropes and two short ropes connected to each other. The process of burying the plastic bag filled with sand and soil and netting the long plastic rope and the short plastic rope on the ground surface was repeated to expand and form a large-area covering grid. View B shows the situation where the three ropes have room for movement inside the ring. This strengthens the restraint of the buried bag on the grid, and also ensures the normally open state of the buried bag. Therefore, the contact points of the film strip and the long rope, the long rope and the short rope, and the short rope and the buried bag handle are all in a state of relatively multiple degrees of freedom. These unconsolidated locations are intended to produce a more effective buffering effect for the wind, which is beneficial to the service life of the grid.

 According to the method of the present invention, the size of the embedding bag is preferably not less than 25 cm × 30 cm. The length of the short rope used for looping on its handle is not less than lm. The tying rope connects the long rope with the short rope ring sleeve, and at least 3 cm of relative movement space is left radially in the ring sleeve. The waste plastic film strips attached to the sides of the grid have four degrees of freedom. In any wind, the moving sand and dust play a soft and soft buffer function. After blowing the dust on the plastic film, it will not rise or cause re-collision to cause larger flying sand. Under wind pressure, sand and dust covered by plastic film are unlikely to collide with each other. The in-situ sand was thus fixed; part of the foreign sand settled down and part of it was blown away. As the area of sand fixation increases, the flow of sandy land becomes weaker, and the flow of sand and dust decreases. The method according to the present invention can effectively slow down the trend of desertification.

 After the rain and snow, the evaporation of the water in the sand bag has an adhesion effect on the sand and dust. At the same time, the surface of the sandy land is covered with a plastic film band to collect the evaporated water, which slows down the rate of water evaporation to a certain extent. Therefore, the ground with sandbags resembles a shallow and wide swamp area, which plays a role in water storage.

 According to the method for windproof and water storage of the present invention, the cost of sand fixation is significantly reduced, and no subsequent care is required. With the increase of the coverage area, the efficiency of sand fixation and water storage is significant.

 The generally used half-buried grass and wood lattice cannot block the leakage and evaporation of rain and snow, which is not conducive to the maintenance of surface water. The grass lattice has a large amount of transportation and embedding work, which is complicated and inconvenient to operate. According to the method of the present invention, the processing of various components on the ground includes the extension of plastic long ropes, the cutting of waste plastic film tapes, and the insertion of plastic film tapes into long ropes until they are packed for transportation, and the processing of various underground components Including the picking and processing of watertight bags, the handling of short-sleeve plastic bags, and the like, all can be completed in advance in non-sandy places, which reduces the workload on the sandy land. The use of waste plastic bags reduces the white pollution in urban and rural areas, and provides a way for environmental protection to turn waste into treasure and turn it into a disadvantage.
