Abstract

The invention is relates to the wind ward and sand fix method in the desert area, wherein the wind ward method is to fill the plastic packaging pouch with sand in the desert area, and to place the sand pouches to a wind ward dam in the perpendicular of the wind direction, or to stack the sand to a perpendicular in the perpendicular of the wind direction, the surface of the sand hill is cover with a grass cushion or a plastic colorful cloth, the sand fix method is to cover the sand area or the sand hill surface with a grass cushion or a plastic colorful cloth, then to press with sand pouches and ropes. The invention is easy to operate with low cost, the sand hurricane damage could be effectively supposed.

Description

Administer the method for hazards of sand storms

Technical field

The invention relates to the method for administering hazards of sand storms, more particularly, is the method about checking winds and fixing drifting sand in desert area.

Background technology

In desert area, high wind blows afloat sand and dust, forms sandstorm, destroys plant growing, the existence of harm animal and human class.Traditional improvement method is plantation trees and an other plant, keeps out the wind with the branches and leaves of plant, fixes the sand with root system, weak point is that the plant survival rate of plantation is low, the planting cost height, and trees cycle of growing into forest is long, in addition windy season, there is not the plant windproof effect of blade poor in the Winter-Spring.In addition, the root system sand-fixing effect of plant is poor, can not reach desirable sand-fixing effect always.

Summary of the invention

The objective of the invention is to overcome the deficiency of existing method, a kind of simple and easy to do, method that implementation cost is low is provided.Use this method, can in than short-term, effectively contain the harm of sandstorm, change the ecological environment of desert area, desert area is become early be suitable for place human and animals and plants existence.The present invention has windproof and fixes the sand two kinds of methods.

Windproof method:

First kind of windproof method: the woven bag of making all size, various profiles with the plastic woven cloth of green or other various pleasing colors, in woven bag, fill sand, the involution sack, make sandbag, the peripheral position of described sandbag can reinforce with following method sometimes easily by pressure break: 1. be nested together with double-deck or multi-layer braided bag and make sandbag.2. twine, tie up with things such as rope bands such as plastic baling band, iron wire, iron plates at the peripheral position of sandbag.3. before sandbag dress sand, in sandbag, fill up some sheet fabrics.In desert area, with aforesaid sandbag build into several rows of parallel to each other, with the dam that keeps out the wind of wind direction approximate vertical, the dam is divided into Pork-pieces zone with the desert to keep out the wind.The height on the described dam that keeps out the wind is 2 meters to hundreds of meters.In addition, on the desert, build the house, pile tall and big massif as paravent with sandbag in the area, air port with described sandbag.

Second kind of windproof method: in desert area, with the mechanized construction instrument sand is piled several rows of parallel to each other and the husky ridge wind direction approximate vertical, the surface of Sha Gang covers with straw or plastics colour bar cloth, and with things such as sandbag ropes straw screen or mat or plastics colour bar cloth is fixed.

The beneficial effect of the windproof method of the present invention is: can effectively stop subaerial wind to play the sand and dust on the face of land, and protection desert area people's life and activity in production, improvement is subjected to the living environment in hazards of sand storms area.

The method of fixing the sand:

First kind of sand-fixation method: weave into straw screen or mat with straw, cover sand ground or sand dune, use fixedly straw screen or mat of things such as sandbag, rope then with straw screen or mat.

Second kind of sand-fixation method: straw or weeds are covered on sand ground or the sand dune, cover with plastic mesh then, will work out net again and fix with things such as sandbag, ropes.

The third sand-fixation method: the plastic woven cloth with green or other pleasing colors covers sand ground or sand dune, fixes with things such as sandbag, ropes then.

The beneficial effect of sand-fixation method of the present invention is: because straw screen or mat and plastic woven cloth can suitability for industrialized production, thereby the dune work progress of the inventive method is fast, and the duration is short, and cost is low; Sand-fixing effect is obvious; Can reduce surface temperature, reduce water evaporation quantity, the ecological environment in improvement desert; Protection planting trees and grass activity makes the desert region become the place of human living.

The specific embodiment one:

Below in conjunction with embodiment anti-method for determining sand of the present invention is further described.

Method 1: make woven bag with the green plastic woven cloth, sand packed in the bag, make sandbag, with sandbag with thing lashings such as plastic baling bands.In desert area, several rows of parallel to each other and the dam that the keeps out the wind wind direction approximate vertical have been built with described sandbag, the dam is divided into blocks of zone with desert area to keep out the wind, the height on the described dam that keeps out the wind is more than 3 meters, and the distance that twice parallel to each other are kept out the wind between the dam is a standard with the sand ground that the wind of crossing the upper end, dam of keeping out the wind can not directly blow between the twice dam.

Method 2: in desert area, with the mechanized construction instrument sand is piled several rows of parallel to each other and the husky ridge wind direction approximate vertical, its surface covers with straw screen or mat or green plastic woven cloth, and with things such as sandbag, ropes straw screen or mat or plastic woven cloth is fixed.

The specific embodiment two:

Below in conjunction with embodiment sand-fixation method of the present invention is further described.

Method 1: weave into straw screen or mat with straw, cover on sand ground or the sand dune, with things such as sandbag, ropes straw screen or mat is fixed then with straw screen or mat.

Method 2: cover sand ground or sand dune with the green plastic woven cloth, with things such as sandbag, ropes plastic woven cloth is fixed then.

Claims

1. method of administering hazards of sand storms, more particularly, it is method about checking winds and fixing drifting sand in desert area, wherein windproof method is characterised in that: method 1: make sack with plastic woven cloth, the sand of packing into is made sandbag, seal, in desert area, build into several rows of parallel to each other and the dam that the keeps out the wind wind direction approximate vertical with described sandbag, the dam is divided into Pork-pieces zone with desert area to keep out the wind; Method 2: in desert area sand is piled the husky ridge of several rows of parallel to each other and wind direction approximate vertical, straw screen or mat or the plastics colour bar cloth that weaves into straw on the surface of Sha Gang cover; Wherein sand-fixation method is characterised in that: will cover sand ground or surface, sand dune with straw screen or mat or the plastics colour bar cloth that straw is weaved into, and with sandbag, rope straw screen or mat or colour bar cloth be pressed solidly then.
