Abstract

The utility model aims at providing a construction structure for furrow-type obliquely-embedded-sand-blocking-net sand ridges and belongs to the technical field of sand engineering and aims at changing the prior sand blocking nets supported by supporting frames into the furrow-type obliquely-embedded-sand-blocking-net sand ridges, in which the supporting frames are not needed for supporting, but instead sand available on site is used to construct the sand ridges in which sand blocking nets are buried and supported fixedly. On a desert, the furrow-type sand ridges which have intervals of 1m and heights of between 10cm and 25cm and the sand blocking nets which have widths of 15cm to 30cm and buried in the furrow-type sand ridges obliquely with angles of 45 degrees are combined to form the furrow-type obliquely-embedded-sand-blocking-net sand ridges.

Description

The constructing structure on the husky ridge of the oblique embedding sediment trapping of furrow formula net

Technical field

The utility model relates to sand control engineering technical field, is specially the constructing structure on the husky ridge of the oblique embedding sediment trapping of furrow formula net.

Background technology

At present, in desert treatment, plastic wire construction net grid and high vertical sediment trapping net have been widely used, implement the interception in flow desert and fix, above-mentioned construction method must be prepared the support matching and support sediment trapping net, therefore not only material cost is high, transportation and construction cost are also high, especially high vertical sediment trapping net, not only to support, require very high, therefore, invent a kind of cost of manufacture cheap, without the constructing structure on the husky ridge of support, easy construction, the oblique embedding sediment trapping of the significant furrow formula of sediment trapping sand-fixing effect net, be the needs of desert treatment.

Technical solution

The technical assignment of the technical problems to be solved in the utility model and proposition is the defect that overcomes prior art, the existing sand-protecting barriers such as stent support sediment trapping net construction net grid and high vertical sediment trapping net of using, change over without stent support, but build up the husky ridge with desert sand drift on the spot, sediment trapping net is tiltedly embedded in to the constructing structure on the husky ridge of the fixing oblique embedding sediment trapping of the furrow formula net of husky ridge intermediate supports.

Applicant has delivered the fixing of < < moving dunes and has utilized > > in 2009, in article, illustrated the principle on splayed net cage sand barrier fixed flow sand dune, illustrated at moving dunes top simultaneously and arranged after splayed net cage sand barrier, due to the husky characteristic toward eminence stream, tall and big moving dunes have just become tall and big mechanical sand barrier, therefore the mechanical sand barrier on textbook are hindered to husky effect formula V=4.5H ²sin a (formula I), is modified as V=4.5H ²+ [H1+H2] ²sin a (formula 2); In (formula 1), V is the husky amount of resistance, the height that H is mechanical sand barrier, and a is the angle of cut.In (formula 2), V is the husky amount of resistance, and the height .H1 that H is mechanical sand barrier is the height of moving dunes windward slope, and H2 is the height of moving dunes leeward slope, and a is the angle of cut.The top of exposing moving dunes due to splayed net cage sand barrier is less than 15cm, if apply mechanically the formula on textbook, be placed in the splayed net cage sand barrier at moving dunes top, it is very little hindering husky effect, but in fact expose the splayed net cage sand barrier that top of sand dune is less than 15cm, owing to there being the moving dunes under cylinder mould sand barrier to make liner, it hinders husky effect far away higher than being arranged on high vertical sediment trapping net on smooth desert, that be highly greater than 150cm.Therefore (formula 1) is inapplicable in the husky effect of resistance of the splayed net cage sand barrier at moving dunes top to constructing, and must just can describe the problem with (formula 2).At moving dunes top, arrange after splayed net cage sand barrier, by splayed net cage sand barrier, tackled the drift sand getting off and be deposited in top of sand dune, by promoting splayed net cage sand barrier, make the lifting that makes progress of moving dunes top, moving dunes just no longer move forward, harmful moving dunes just become useful mechanical sand barrier, and so the mechanical sand barrier of height, is cannot accomplish with the high vertical sediment trapping net that any method builds.Thereby the function that has shown the efficient intercepting of moving dunes desert.But the mechanical sand barrier being so efficiently easy to get on desert, is not also familiar with by people at present, fails so far to find correlation theory and experimental data in textbook.What on textbook, introduce is high vertical sand barrier to be arranged on to the waist of moving dunes, reaches the object of scabbling moving dunes, and people still process moving dunes as disaster so far.

The height that can be transformed into sand-protecting barrier due to the height on the He Sha ridge, sand dune is not yet familiar with by people, so applicant is managing to prove by engineering practice.

Utility model content

Sediment trapping net described in the utility model be wide cut between 15cm to 30cm, the plastic wire of degree of porosity between 35% to 55%, weedtree fiber boom net, Cotton Stalk fiber grid block.

The constructing structure on the husky ridge of the oblique embedding sediment trapping of furrow formula net, it is characterized in that: on desert, interval 1m, the husky ridge of the furrow formula of height between 10cm to 25cm and wide cut between 15cm to 30cm, be inclined to the sediment trapping net of 45° angle potting in the husky ridge of furrow formula and constitute the husky ridge of the oblique embedding sediment trapping of furrow formula net; The husky ridge of the oblique embedding sediment trapping of furrow formula net be with mechanical implement wide cut at the sediment trapping net between 15cm to 30cm, towards leeward direction, be inclined to 45° angle, top margin upward, hang down in base contact with Desert Sand, the extension of a lot of interval 1m proper alignment; Sediment trapping net one face tilt extends, the Desert Sand of both sides for one side, by the sediment trapping net of inclination be clipped in the middle heap buried become height between 10cm to 25cm, the husky ridge of the oblique embedding sediment trapping of furrow formula net of interval 1m; Low ebb between the husky ridge of the oblique embedding sediment trapping of furrow formula net sediment trapping net just can be planted psammophytes.
