Description
Technical Field
The invention relates to the field of highway protection, in particular to a covering structure of a sand blocking net for slowing down burying of a moving dune.
Background
At present, a highway protection system usually takes sand blocking, sand fixing, sand transporting and sand guiding measures as main measures, adopts a multi-belt integrated protection mode, and is formed by combining and assembling various sand barriers, wherein the first measure usually takes a HDPE grid plate or a high vertical sand barrier as a main sand blocking measure, the second measure usually takes a grass square grid and a low vertical sand barrier as a main sand fixing measure, and then a plant sand fixing system is taken as a main sand fixing system, and different measures such as sand transporting, sand guiding and the like are correspondingly used in different regions; the sand storm disaster statistics of the operated roads can discover that the protection system can prevent the sand damage phenomenon of the desert roads to a greater extent, but in the practical application process, the sand blocking measures at the outermost sides of the protection system usually fail in a shorter time, therefore, line workers have to observe the line protection system for many times in a shorter time and need to timely perform sand cleaning or heighten protection measures and other measures on the protection failure sections for treatment; this phenomenon is more pronounced in mobile desert areas, for which reason sand dunes are usually moving at a fixed speed, so that the sand blocking nets are buried.
In the patent with publication number CN204919521U in the area of the flowing desert, three measures are taken to control the flowing desert, which can effectively prevent the sand dune from moving, but the three measures are taken simultaneously, so the cost is high and the feasibility needs to be further questioned.

In order to solve the problems, the invention provides a covering structure of a sand-blocking net for slowing down burying of a moving dune, which can achieve the effects of weakening wind and sand surface, achieving the purposes of reducing wind speed and delaying the movement of the dune, greatly prolonging the failure time of the sand-blocking net and greatly improving the utilization rate of the sand-blocking net by covering the front of the sand-blocking net and the space between the first sand-blocking net and the second sand-blocking net.
In order to achieve the purpose, the invention adopts the technical scheme that:
the utility model provides a slow down that it hinders covering structure of sand net to flow dune buries, cover the net and adopt porosity 55%, aperture 1.5mm, ageing resistance nylon of 0.5mm silk footpath to compile the net, arrange in the middle of two sand nets that hinder to extend to the sand dune windward side slope foot before hindering the sand net, the edge is fixed with 1 No. 1 bamboo borer that 1m is long, fixed range apart from covering net edge 9m, cover and adopt 0.5m long No. 2 bamboo borer to encrypt in the middle of the net, different cover and overlap and connect 20cm between the net, overlap the portion and fix with No. 1 bamboo borer.
The invention relates to a covering structure of a sand blocking net for slowing down burying of a floating dune, which is arranged by the following steps:
s1, arranging covering nets in front of the sand blocking nets and between the two sand blocking nets, wherein the covering nets extend to a slope toe of a sand dune windward side in front of the sand blocking nets, the edges of the slope toe are fixed by No. 1 bamboo borers, the fixed range is 9m away from the edges of the covering nets, the length of the bamboo borers is 1m, the distance between the bamboo borers is 3.0m, and the covering nets are prevented from being uncovered by wind; the middle of the covering net is encrypted by No. 2 bamboo drill rods with the length of 0.5m, the distance is 1.5m, the covering net is exposed by 0.1m and is vertical to the ground, different covering nets are connected in an overlapping mode by 20cm, the overlapping parts are fixed by No. 1 bamboo drill rods, the fixed distance is 1.5m, plastic belts are used for binding, and the binding distance is 0.5 m;
s2, determining the position of the upright column, inserting the upright column into a concrete foundation of 50cm, wherein the insertion depth is 45cm, penetrating an iron wire into the upright column after the upright column is installed, and keeping the iron wire elastic and uniform to form a net rack;
s3, digging a trench 15cm wide and 15cm deep below the net rack, uniformly and flatly hanging the sand-blocking net on the net rack by using a plastic belt, reversely folding the iron wire passing through the top of the upper end, wherein the reversely folded width is about 5cm, vertically placing the lower end in the trench, burying and compacting the trench by using sand, and the width is 15 cm; the diagonal brace ground anchor is driven into the ground at an angle of 60 degrees with the ground, so that the diagonal brace and the ground form an angle of 45 degrees, and the tightness of the diagonal brace is adjusted, so that the plane of the sand blocking net is basically vertical to the ground;
s4, planting sand plants such as Salix psammophila, floral rods and haloxylon ammodendron in the middle of the sand-blocking fence, and fixing a sand dune by the plants.
Furthermore, the distance between the upright posts is 3m, and the total height is 2.45 m.
Furthermore, the distance between the plastic belts for fixing the sand blocking net is about 40 cm.
Furthermore, the sand-blocking net adopts an anti-aging HDPE grid plate, the height is 2.0m, and the porosity is 50%.
In the above scheme, the sand dune covers the net through covering before blocking the sand net, reduces the contact of sand grain and air current to reach and prevent that the sand dune that flows from burying and blocking the sand net, secondly hinder the sand net at first way and hinder covering the net between the sand net with the second way, can prevent to the at utmost that the sand dune that flows from burying and blocking the sand net.
Meanwhile, the action between air flow and sand particles can be isolated by a net covering measure on the moving sand dune, so that the splashing of the sand particles is reduced, the volume fraction of the sand particles in the sand flow in windy weather is reduced, and the flowing of the sand is reduced; the purpose of fixing the moving dune can be achieved by a mesh covering measure for the moving dune, the structure of the device is equivalent to a wind shielding dike, the purpose of reducing the wind speed of a sand area can be achieved, and the movement of the moving dune is restrained; the method has the advantages that the flowing sand dunes are covered with the net, so that the wind erosion phenomenon can be effectively prevented, the sand interface is favorably skinned, and the ecological environment of the sand area is favorably restored; the sand-blocking net dunes have more water in the inter-dune areas, can be planted with sand plants, promotes ecological restoration, and achieves the purpose of fundamentally governing sand dunes.
