Abstract

A bank-like protection screen applied to hold the sand and prevent the loss of the water and soil comprises a bag (1) and stuffing material (2); the stuffing material (2) placed inside the bag (1). The stuffing material (2) is mixed barely with gravel, sand or soil, or with more than two of the three. The bag (1) is a hollow long bag. The bags (1) with the stuffing material (2) inside are mutually connected to form an integrated screen with the assistance of the connecting belt (4), and the integrated screen is stabilized on the ground by pillar (3). The screen is paved on the ground in parallel, or in the shape of grid or rhombus. The utility model can not only prevent the sand from flowing and the water and soil from losing, but also can protect the roadbed or the bank.

Description

Can press ridge type barrier husky and that prevent erosion

Technical field

The utility model relates to a kind of ridge type barrier that can press sand and prevent erosion, the facility that belongs to control of desert and prevent erosion.

Background technology

Current, the desertification land area of China has reached more than 200 ten thousand square kilometres, and is also expanding with more than 2,000 square kilometres speed every year, so prevent that the situation of desert extension is quite severe.Equally, China's soil erosion problem is also very outstanding, and is the most serious with the black earth soil erosion in the loess of northwest, southern red soil, northeast especially.China's soil erosion area has accounted for 38.2% of area now, causes very big harm for the socio-economic development and people life.In addition, at the roadbed side slope of some highways, railway, the sloping bank place in reservoir, river is also formed soil erosion easily after the rain drop erosion, even the landslide occurs, and roadbed and sloping bank are badly damaged.The way of present protection is partly imbedded wheat straw, straw etc. underground exactly on roadbed and sloping bank, reaches the purpose of fixing the sand, consolidating soil with this.But this facility is just all gone behind be everlasting a strong wind or heavy rain, does not in fact play effect.

The content of utility model

The technical problems to be solved in the utility model is for overcoming the described deficiency of background technology, and provide a kind of simple in structure, cost is lower, easy enforcement, result of use are good, can press ridge type barrier husky and that prevent erosion.

Technological improvement of the present utility model is: this barrier is to be made of outer bag and filler, and filler is positioned at outer bag.

Further technological improvement of the present utility model is: said filler is mixed by one or more of rubble, sand, soil.Said outer bag is the hollow bag of a strip.In be filled with filler outer bag be connected to each other by connecting band and form whole barrier, and be fixed on ground by stanchion.

The good effect that the utility model produced is: simple in structure, material is easy to get, cost is lower and easy construction, mainly be that rubble, sand, soil etc. are put in the outer bag of strip, the shallow slot that a plurality of barrier levels is connected and places ground to shovel along the hillside fields, fix by stanchion and ground again, form the facility of similar ridge, to stop flowing and soil erosion of sand.This barrier is for the roadbed side slope of highway, railway, and reservoir, river sloping bank etc. has protection effect preferably, and cost is very low.To both can be arranged in parallel by multirow after this a plurality of barriers connections, also can be according to situation grid-shaped or rhombus are put the effect that the weight of himself just can play and press sand, keep off sand on the spot.

The specific embodiment

As shown in Figure 1, in the outer bag 1 of a strip hollow, be filled with the filler 2 that constitutes by rubble, sand, soil, weeds etc.Tighten at the two ends of outer bag 1, and its termination can be connected by the outer bag 1 of connecting band 4 and another one, to increase its length gradually.Said outer bag 1 can be Polywoven Bag, gunnysack etc.But this barrier parallel shape after the connection or latticed or diamond shaped are laid in the shallow slot that has dug, but the overwhelming majority is basseted, fix with stanchion 3 and ground again, form the ridge formula barrier net of an integral body, can stop the loss of flowing and preventing water and soil of sand.Add the fixation of own wt and stanchion 3, it is moved, so can protect highway, railway bed and reservoir, river sloping bank not to be damaged effectively.

Claims

1, a kind of ridge type barrier that can press sand and prevent erosion is characterized in that it is made of outer bag (1) and filler (2), and filler (2) is positioned at outer bag (1).

2, as claimed in claim 1ly can press ridge type barrier husky and that prevent erosion, it is characterized in that said filler (2) is mixed by one or more of rubble, sand, soil.

3, the ridge type barrier that can press sand and prevent erosion as claimed in claim 1 is characterized in that said outer bag (1) is the hollow bag of a strip.

4, the ridge type barrier that can press sand and prevent erosion as claimed in claim 1, the outer bag (1) that is filled with filler (2) in it is characterized in that is connected to each other by connecting band (4) and forms whole barrier, and is fixed on ground by stanchion (3).
