Abstract

The utility model relates to an engineering technical field, concretely to a cylinder mould sheet for constructing a splay cylinder mould sand barrier. The cylinder mould sheet has a cylinder mould surface which is made of a plastic wire screen with a porosity between 10% and 25% and a width between 25cm and 50cm; and supporting bars are arranged at an interval of 50cm on the cylinder mould surface and tightly stretch the cylinder mould surface to form the cylinder mould sheet.

Description

A kind of cylinder mould sheet of constructing splayed net cage sand barrier
Technical field
The utility model relates to field of engineering technology, is specially a kind of cylinder mould sheet of constructing splayed net cage sand barrier.
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 cylinder mould sheet of constructing splayed net cage sand barrier of easy construction, use the utility model cylinder mould sheet splayed net cage sand barrier of on the desert, constructing, 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 200910224492.1 to application number, and denomination of invention is that " a kind of splayed net cage sand barrier and constructing structure thereof " (my application) is for a kind of special project application of constructing the cylinder mould sheet of splayed net cage sand barrier.
A kind of cylinder mould sheet of constructing splayed net cage sand barrier described in the utility model 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 3m to 100m as required.
Description of drawings
Fig. 1 looks schematic diagram for the utility model cylinder mould sheet master.
Fig. 2 is the utility model cylinder mould sheet cross sectional representation.
1 is the cylinder mould sheet in the accompanying drawing, and 2 is the cylinder mould face, and 3 is support bar, and 4 is half root in the support bar, and 5 is outer half root of support bar, and 6 is grab.
The specific embodiment
Now be further described in conjunction with 1,2 pairs of a kind of cylinder mould sheets of constructing splayed net cage sand barrier described in the utility model of diagrammatic sketch: cylinder mould sheet 1 by degree of porosity between 10% to 25%, the plastic silk screen of wide cut between 25cm to 50cm is as cylinder mould face 2, the degree of porosity of cylinder mould face and wide cut be selected specification and size in above-mentioned scope as required, interval 50cm is equipped with a support bar 3 on the cylinder mould face, support bar tight the cylinder mould face, the top margin of support bar and cylinder mould face and base intersect vertically and and the fixing formation of cylinder mould face cylinder mould sheet.Vertically separately interior half root 4 of support bar 3 and outer half root 5, cylinder mould face 2 tight be embedded in the centre of half root and outer half root in the support bar, the top of half root is shaped on a grab 6 in the support bar, the effect of grab 6 two is thrown the net cage sheet combination when constructing splayed net cage sand barrier before and after being, grab is stuck on the top margin of opposite cylinder mould sheet, the cylinder mould sheet can not got off from the top margin landing of opposite cylinder mould sheet, make the splayed net cage sand barrier structure firm.The length of cylinder mould sheet can be selected between 3m to 100m as required.
The available plastics of cylinder mould sheet are produced in enormous quantities in factory.
