Abstract

The utility model relates to the technical field of engineering, in particular to a splayed cylinder mould sand-protecting barrier and a construction structure thereof. The splayed cylinder mould sand-protecting barrier is formed by combining a front cylinder mould plate and a rear cylinder mould plate; the cylinder mould plates take plastic wire meshes the porosity of which is between 10 and 25 percent and the width of which is between 25 and 50cm as cylinder mould surfaces; a supporting rod is arranged on the cylinder mould surface at interval of 50cm and fixed with the cylinder mould surfaces to form the cylinder mould plates; the front cylinder mould plate and the rear cylinder mould plate are tightened in the left direction and the right direction; top sides of the front cylinder mould plate and the rear cylinder mould plate are mutually abutted; bottom sides of the front cylinder mould plate and the rear cylinder mould plate are separated to form a splayed shape; and a clamping hook at the top of the supporting rod faces downwards to clamp the top side of opposite cylinder mould plate to form the splayed cylinder mould sand-protecting barrier.

Description

A kind of splayed net cage sand barrier and constructing structure thereof
Technical field
The utility model relates to field of engineering technology, is specially a kind of splayed net cage sand barrier and constructing structure thereof.
Background technology
At present, the mechanical sand barrier of using in the desert treatment engineering mainly is with bavin, grass, straw, branch, cobble, clay and plastic wire etc. various forms of obstructions to be set on the desert to come sediment trapping to fix the sand.In the desertification regions of arid, because the plant seedling can't be grown up, often cause the ecological recovery failure in drift sand, therefore, need not the water mechanical sand barrier of tackling quicksand fast, status in sand control and effect are extremely important.The existing mechanical sand-protecting barrier is divided into three major types: a class is the flush system sand-protecting barrier, and a class is half concealed type sand-protecting barrier, and a class is the vertical type sand-protecting barrier; Flush system sand-protecting barrier and half concealed type sand-protecting barrier will be laid blind comprehensively on the desert, so consumable quantity is big, the cost height, therefore can not be in sand control engineering large-scale application, and flush system sand-protecting barrier and half hidden sand-protecting barrier can only fix the sand, and can not tackle the desert drift sand; Existing vertical type sand-protecting barrier, reason owing to technology, can only be as the alternative of shrub, the sediment trapping function only rest on as planted one row bushes effect, reason is that existing technology can't be constructed the vertical type sand-protecting barrier on the dune ridge line of top of sand dune, can not use the sand dune as sand-protecting barrier, because on the dune ridge line, having stablized of vertical type sand-protecting barrier into big problem, very fast meeting is washed in a pan empty bottom by wind and is lodged; Present vertical type sand-protecting barrier is for the resistance that reduces wind and avoid being buried by drift sand, the sand-protecting barrier degree of porosity is mostly greater than 40%, take to allow drift sand pass through the mode of being detained again behind the vertical type sand-protecting barrier, when drift sand moves to the distance of leaving 20 times of sand-protecting barrier height, sand-protecting barrier just loses the function to its delay, if no longer establish sand-protecting barrier one, drift sand can drive straight in again, if construction is gone down together, not only drift sand still is in runaway condition, and cost is also very high.
Summary of the invention
The utility model aim to provide a kind of simple in structure, cost is low, the splayed net cage sand barrier of easy construction and constructing structure thereof, use on the desert, the construct splayed net cage sand barrier of Great Wall style of the utility model, drift sand interception in desert is piled into sand bar under cylinder mould, reach the fixing desert of flowing, stop the purpose of desert expansion.The utility model is to be 200910141032.2 to application number, and denomination of invention is the special project application of " splayed net cage sand barrier and constructing structure thereof " (my application) for another splayed net cage sand barrier and constructing structure thereof.
Splayed net cage sand barrier described in the utility model is combined by preceding cylinder mould sheet and back cylinder mould sheet, and preceding cylinder mould sheet is identical, measure-alike with back cylinder mould chip architecture, can exchange; The cylinder mould sheet by degree of porosity between 10% to 25%, the plastic silk screen of wide cut between 25cm to 50cm is as the cylinder mould face, degree of porosity and wide cut be selected specification in above-mentioned scope as required, interval 50cm is equipped with a support bar on the cylinder mould face, vertically separately interior half root of support bar and outer half root, interior half roots and tops is shaped on a grab, the cylinder mould face tight be embedded in the centre of the inside and outside two halves root of support bar, the top margin of support bar and cylinder mould face and base intersect vertically also and the fixing formation of cylinder mould face cylinder mould sheet, and the length of cylinder mould sheet can be selected between 3 meters to 100 meters as required.
A kind of splayed net cage sand barrier described in the utility model and constructing structure thereof comprise the following steps:
1, tight preceding cylinder mould sheet and back cylinder mould sheet left and right directions, front and back cylinder mould sheet top margin is close to mutually, the base separately constitutes splayed, the angle on front and back cylinder mould sheet and ground is greater than 45 °, less than 70 °, the support bar top of the support bar top of preceding cylinder mould sheet and back cylinder mould sheet is close to the intersection of staggering mutually, and the grab of support bar top down, block the other side's cylinder mould sheet top margin, constitute splayed net cage sand barrier.
2, the structure of splicing about adjacent splayed net cage sand barrier, it is the left end support bar of right side cylinder mould sand-protecting barrier, stride across left side cylinder mould sand-protecting barrier right-hand member support bar, be close to left side cylinder mould right-hand member support bar, be pressed on the right-hand member cylinder mould face of left side cylinder mould, grab blocks the top margin of left side cylinder mould right-hand member cylinder mould face simultaneously, adjacent cylinder mould sheet is stitched together with regard to left and right directions, desert sand at the base of cylinder mould sand-protecting barrier pile things on 3cm to 15cm thickness, the front and back cylinder mould sheet of cylinder mould sand-protecting barrier just can not be forward, after, a left side, right, on, following direction displacement is guaranteed that the cylinder mould sand-protecting barrier is stable and is stood the attack of Desert Storm.
3, splayed net cage sand barrier is splicing about with identical constructing structure on the desert one by one, extends tens meters, hundreds of rice, a few km, tens kms, hundreds of km along design route.
When drift sand is tackled by splayed net cage sand barrier and heap is high gradually before and after the cylinder mould sand-protecting barrier, when extremely only exposing the top of cylinder mould, the cylinder mould sheet is pulled out from sand drift, again be spliced into splayed net cage sand barrier in a manner described successively at the sand drift top, buried the back by sand drift so again and again and promote splicing again, the desert drift sand just is intercepted at below the splayed net cage sand barrier, sand dune under the cylinder mould sand-protecting barrier is along with the promotion of cylinder mould sand-protecting barrier is increased gradually, the desert drift sand is under the interception of cylinder mould sand-protecting barrier, be piled into sand bar, sand bar is piled up high more, and the drift sand that can hold is many more, the sediment trapping effect is just good more, needs to promote the time interval of cylinder mould sand-protecting barrier long time by time.So just utilize drift sand interception desert, desert drift sand, reach the purpose in the fixing desert of flowing.
