Description

A kind of sand-protecting barrier structure of fixing the sand

Technical field

The utility model relates to a kind of sand-protecting barrier that fixes the sand, and relates in particular to degradable water conservation paper.

Background technology

The tradition sand-protecting barrier is the blind of on Shamian Island, making with materials such as faggot, stalk, clay, branch, lath, cobbles, is to subdue wind speed, the fixing husky effective engineering of showing to fix the sand measure.Its cardinal principle is: on the route that stream passed through; No matter run into stopping of any obstruction, wind speed will be affected and reduce, the part of the sand of carrying under one's arms will be deposited on obstruction around; Reduce the sedimentary loading of stream with this, thereby play the effect of control hazards of sand storms.The main effect of sand-protecting barrier is fixedly moving dunes and semi-mobile dune.After the sand ground that flows is fixing, just can recover surface vegetation naturally in 1 year, this is both economical in sand control at present, effective again a kind of common method.

Sand-protecting barrier commonly used at present mainly contains:

1, plant sand block is that raw material vertically inserts on the sand dune in the latticed groove of offering, the landfill sand is with fixing sand-protecting barrier material in groove then with tangerine bar, branch etc., and part material is exposed on the Shamian Island, the grid-like one by one sand-protecting barrier of formation;

2, straw checkerboard barrier sand-protecting barrier, principle is the same, and material is to be raw material with straw, tangerine bar.

3, the polybag sand-protecting barrier is durable, non-degradable;

4, PLA geotechnique sand-protecting barrier.Introduce from Japan.With the biodegradable synthetic fibers that polylactic acid melt spins and produces, dustproof effect is good, and cost is very high.

The cost of preceding two kinds of sand-protecting barriers is 1000～1300 yuan every mu, and is relatively low, and the peasant is convenient to grasp and is used; But laying speed is slower, and the raw materials consumption amount is bigger, the third non-degradable; Environmental pollution is bigger, and the 4th kind of cost is the highest, and every mu up to 3300 yuan.

The utility model content

The utility model technical problem to be solved is to provide a kind of laying convenient and swift, with low cost, simultaneously can not fix the sand the sand-protecting barrier structure to what environment polluted.

The utility model is realized through following technical scheme:

A kind of sand-protecting barrier structure of fixing the sand is characterized in that:

On the Shamian Island of sand ground that flows, laterally laying many parallel laterally fixing the sand manages; Manage perpendicular to laterally fixing the sand to manage, on Shamian Island, lay many parallel vertically fixing the sand; Laterally fix the sand to manage and vertically fix the sand to manage square crossing and lay; Pipe network lattice sand-protecting barrier is fixed the sand in formation, each grid cell of sand-protecting barrier be shaped as square

Same vertically fix the sand to manage with adjacent two two crosspoints of laterally fixing the sand to manage on, vertically fix the sand pipe to lay respectively at and laterally fix the sand to manage upper and lower both sides,

Adjacent two vertically fix the sand to manage with same two crosspoints of laterally fixing the sand to manage on, vertically fix the sand pipe to lay respectively at and laterally fix the sand to manage upper and lower both sides,

Laterally fix the sand to manage with the Shamian Island that vertically fixes the sand below the tube end on offer the landfill groove, laterally fix the sand to manage with the two ends of vertically fixing the sand to manage being embedded in the landfill groove,

Laterally fix the sand to manage and vertically fix the sand to manage degradable water conservation waterproof paper tube, fill with the sand of living in the pipe into diameter 80～140mm, wall thickness 1～3mm.

The inventive concept of the utility model is:

The mobile sand ground that selection need to be administered is given according to the wind speed degree, at terrain and to be fixed the sand after pipe fills with sand alive, with laterally parallel and parallel longitudinal fix the sand to manage after square crossing lays, just form the grid sand-protecting barrier.Through fixing the sand to manage the grid sand-protecting barrier that is laid to, stop the displacement of flowing, stop drift sand of sand with the height of pipe, reach the purpose of tackling quicksand and vegetation recovery.

The material that fixes the sand to manage is a kind of environmental protection water conservation waterproof paper, and water conservation paper is waterproof, ventilative not only, and is difficult for permeating, can slowly degrading, and during fixing the sand, can play good sand fixation, and degraded fully after drift sand is fixing can not pollute environment.Experiment showed, environmental protection water conservation waterproof paper tube in the desert, can degrade after 360～400 days, can not contaminated soil, as long as the condition of rainfall is arranged before the degraded, can grow out very soon in the weeds of fixing the sand in the grid sand-protecting barrier, reach the final purpose of nature restore vegetation.

Laterally fix the sand pipe with vertically fix the sand pipe bury be full of sand after, alternatively up and down passes, and intersects the all-in-one-piece net structure, simultaneously, offer in the landfill groove on the Shamian Island of every endpoint location that fixes the sand to manage, utilize the sand of living to bury to fix the sand tube end.Under the prerequisite that does not have groove to bury underground, this structure can effectively prevent the distortion, loose under long-term dust storm corrodes of sand-protecting barrier integral body.Laterally fix the sand to manage and vertically fix the sand to manage the depth of burying of two ends in the landfill groove and be preferably 15～30mm.

Compare with the grid sand-protecting barrier of shapes such as rectangle, triangle, prismatic, circle, the dustproof effect of square net sand-protecting barrier is better.Experimental result proves, square sand-protecting barrier grid, and its core is only emptied about about 100mm by the vortex that air-flow produces, and dustproof effect is best; And the grid unit of its shape such as pane, its core is but very dark by sapping, and it is bad to fix the sand dustproof effect.Therefore according on the spot wind speed size, fix the sand the length of side of each grid cell of pipe network lattice sand-protecting barrier to be generally 1～3m, the preferred grid unit is of a size of 2m * 2m.

In addition, in the ordinary course of things, wind is the carrying grains of sand in apart from about the 100mm of the face of land mainly, exceed this height, and sediment transport seldom.Therefore, fix the sand the height of sand-protecting barrier generally also about 100mm, selecting thus to fix the sand to manage diameter is 80～140mm, and preferred diameter is 100mm.

Can during fixing the sand, arrive good sand fixation for guaranteeing to fix the sand to manage, drift sand can in time be degraded again after fixing fully, fixes the sand thickness of pipe wall to be generally 1～3mm, is preferably 1mm.

The beneficial effect of the utility model is:

To fix the sand to manage the surface that sand-protecting barrier is laid immediately on sand when 1, laying, and only need to fix the sand to manage two ends and be fixed under the Shamian Island, and need not to offer groove, convenient and quick construction at Shamian Island;

2, degradable water conservation waterproof paper tube is cheap, easy to process, and be easy to the user and accept,

3, degradable water conservation waterproof paper fixes the sand to manage convenient transportation, and freight charges are extremely low;

4, the fixing back of Shamian Island water conservation paper tube can regularly be degraded, and can not pollute environment.
