Description

A kind of constructing structure of fillet Sand-fixation net sand-protecting barrier

Technical field

The utility model relates to sand control engineering technical field, specially a kind of constructing structure of fillet Sand-fixation net sand-protecting barrier.

Background technique

Currently, being widely used net grid sand-protecting barrier, sandbag sand-protecting barrier, straw checkerboard barrier sand-protecting barrier in desert treatment and implementing convection current The fixation in dynamic desert, then plants psammophytes on the desert secured.Since the straw transportation cost of straw checkerboard barrier is arranged very Height, construction cost is also very high, and stalk straw checkerboard barrier 3 years will lose function of fixing the sand because of weathering corrosion, makes the plant planted weight Newly face by the condition of dust storm erosion；Net grid and sandbag sand-protecting barrier unit area building cost are more much higher than straw checkerboard barrier sand-protecting barrier, are big faces The financial burden that product sand control engineering cannot be born.Applicant provides a kind of method that the U-shaped Sand-fixation net sand ridge is fixed the sand, U-shaped before Sand-fixation net sand ridge sand-fixing effect is good, and cost is also reduced than net grid sand-protecting barrier, but since the section of U-shaped Sand-fixation net is in U-shape, It constructs more troublesome, there is also in moving dunes windward slope by the phenomenon that being turned over of eroding.Therefore, a kind of new sand-protecting barrier is invented, Overcome the defect of above-mentioned sand-protecting barrier, has been the needs of control of desert.

Summary of the invention

The technical problems to be solved in the utility model and the technical assignment of proposition are to overcome the deficiencies of existing technologies, and provide one The constructing structure of kind fillet Sand-fixation net sand-protecting barrier.The constructing structure of fillet Sand-fixation net sand-protecting barrier is according to " at the top of sand-protecting barrier and desert landforms Sediment trapping is combined to fix the sand function law " principle analysis show that " sand-protecting barrier combines at the top of the landforms of desert sediment trapping and fixes the sand function Can law " character express be：" sand-protecting barrier at the top of desert landforms (moving dunes, longitudinal dune, Sha Geng) is set, there is fixed flowing The function in desert, the size of function are equal to 1.42 times, the height of desert landforms, in addition the sum of sand-protecting barrier height at the top of the landforms of desert Square, multiplied by the length of sand-protecting barrier on contour at the top of the landforms of desert." its formulation is：

V=1.42 (H1+H2)²L

V is amount of drift sand in formula, and H1 is the height of desert landforms (moving dunes, sand bar, Sha Geng), and H2 is desert landforms top The height of portion's sand-protecting barrier, L are the length of sand-protecting barrier on contour at the top of the landforms of desert.

1.42 data in formula are to constitute flowing according to the gradient angle of repose (maximum angle of repose is 35 ° of angles) of moving dunes What the area statistics of sand dune section triangle obtained, when moving dunes are (including recessed in longitudinal dune, Sha Geng, Sha Kan, grid sand-protecting barrier Face) slope surface somewhere, angle be more than angle of repose when, sand will collapse downwards, collapse to the gradient be lower than angle of repose place, just from So stop collapsing.

Straw checkerboard barrier sand-protecting barrier and sandbag grid sand-protecting barrier on desert fix the sand building site, one can see that sand-protecting barrier grid one by one It is interior, it is the sand pit being recessed down one by one.The size of straw checkerboard barrier sand-protecting barrier is generally in 1m × 1m between 1.5m × 1.5m, strong wind It, the sand in straw checkerboard barrier is washed in a pan away in strong wind punching, and the desert in straw checkerboard barrier will be recessed down, when the slope surface gradient in straw checkerboard barrier is more than Angle of repose, slope surface will collapse, under straw checkerboard barrier it is husky will the pit into straw checkerboard barrier sand-protecting barrier collapse, in some dust storm mouths, when The Desert Sand of straw checkerboard barrier inside recess is washed in a pan away, the sand under straw checkerboard barrier sand-protecting barrier, just the pit constantly into straw checkerboard barrier sand-protecting barrier by continuous punching It collapses, once husky by naughty sky below straw checkerboard barrier sand-protecting barrier, straw checkerboard barrier sand-protecting barrier just disintegrates.This phenomenon is being provided with straw checkerboard barrier sand The dust storm mouth for hindering building site, is very common.Such phenomenon is fixed the sand building site in sandbag grid sand-protecting barrier, shows more prominent, former It is bigger than straw checkerboard barrier because being the specification of sandbag grid sand-protecting barrier, generally in 1.5m × 1.5m between 2m × 2m, strong wind day sandbag grid Pit in sand-protecting barrier can firmly get more, the sandbag grid sand-protecting barrier on the windward slope of desert, strong wind than the pit in straw checkerboard barrier sand-protecting barrier , since husky constantly rushed by strong wind in sandbag grid is washed in a pan away, the sand below sandbag sand-protecting barrier just constantly collapses to the pit of sandbag grid for it It falls into, sandbag is fallen into hole therewith, and sandbag dune work just becomes in disorder.

It, can according to the angle number that stops of " sand-protecting barrier combine at the top of the landforms of desert sediment trapping fix the sand function law " and sand dune To calculate：Pit in 2m × 2m grid sand-protecting barrier, depth about 60cm.Pit in 1m × 1m grid sand-protecting barrier, depth about 30cm, Pit in 0.5m × 0.5m grid sand-protecting barrier, depth about 15cm.To desert fix the sand building-site detection, conclusion is also to be consistent. It can be seen that the interval between sand-protecting barrier is smaller, by erosion at pit it is also more shallow, the foundation of sand-protecting barrier is more secured.Therefore, work as U The spacing on the shape Sand-fixation net sand ridge, especially in windward slope, can equally be collapsed when being greater than 1m by erosion.If reducing U-shaped Sand-fixation net The spacing on the husky ridge must increase engineering cost, therefore, manufacture experimently miscellaneous new sand-protecting barrier, to reduce project cost, improve engineering Quality is the routine work of applicant these years.

By month after month being compared on desert to various sand-protecting barrier repetition tests throughout the year, it has been found that wide cut 35cm, it is long The Sand-fixation net doubling of 3m to 10m, horizontal direction are vertically inserted on the windward slope of moving dunes, and strong wind day, Sand-fixation net is soon It is washed in a pan and comes out by strong wind punching, included away by wind.Identical wide cut, the fillet Sand-fixation net doubling of long 12cm to 50cm, horizontal direction is vertical It inserts on the windward slope of moving dunes, undergoes strong wind several times, but see that fillet Sand-fixation net is safe and sound, fillet Sand-fixation net periphery Desert Sand is walked by strong wind erosion, and the top margin of fillet Sand-fixation net becomes the top of a sand hill, this fillet Sand-fixation net is not only protected Inherently safe is demonstrate,proved, the Desert Sand for also fixing surrounding forms a small sand hill.This is an of great value discovery, this hair Now illustrate Sand-fixation net of the potting on desert, length is longer, is more subject to wind erosion by strong wind and includes race, is about 12cm to 50cm Fillet Sand-fixation net it is just very safe.According to this discovery, people can be the narrow of 12cm to 50cm at length Sand-fixation net cutting Item is spaced 50cm to 200cm on desert and inserts an embedding fillet Sand-fixation net, constitutes fillet Sand-fixation net sand-protecting barrier one by one, strong wind day Fillet Sand-fixation net sand pier one by one is formed under wind erosion, can effectively be prevented strong wind from degrading desert, not only be may insure fillet in this way The dosage of Sand-fixation net can also be greatly lowered in the safety of Sand-fixation net sand-protecting barrier, and the cost of dune work is greatly lowered.
