Abstract
The invention aims to provide embedded sand blocking nets and beaches and a construction method thereof, which belong to the technical field of desertification control engineering, and aim to change the existing sand-protecting barriers for supporting sand blocking nets by supports into the embedded sand-blocking nets and beaches which are not supported by supports and are supported and fixed through embedding the sand-blocking nets in the middle of the sand beaches by desert sand in site. The sand blocking nets provided by the invention are plastic nets, weed tree fiber fence nets and cotton stalk fiber fence nets with the width between 15cm and 55cm and the porosity between 35%-55% as well as plastic nets with the width between 100cm and 300cm; when being constructed on the top of moving dunes, the embedded sand-blocking nets and beaches can be used for fixing the moving dunes; when being constructed on the top of sandbanks which are mechanically piled and built, the embedded sand-blocking nets and beaches can form the sand blocking banks with the embedded sand-blocking nets and beaches; and the embedded sand-blocking nets and beaches can be constructed to be of a strip type, a z shape and a grid square shape. The embedded sand-blocking nets and beaches and the construction method provided by the invention can be widely applied to sand blocking engineering and sand stabilization engineering.
Description
Technical field
The present invention relates to the sand control engineering technical field, be specially the husky ridge of potting formula sediment trapping net and job practices thereof.
Background technology
At present, in desert treatment, plastic wire construction net grid and high vertical sediment trapping net have been widely used, the interception in enforcement flow desert and fixing, above-mentioned job practices must be prepared the support that matches and support the 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 support is required very highly, also blown down by strong wind easily and lost efficacy, therefore, it is cheap to invent a kind of cost of manufacture, need not support, easy construction, the husky ridge of the significant potting formula of sediment trapping sand-fixing effect sediment trapping net and job practices thereof have been the needs of desert treatment.
To disclosure of an invention
Technical solution
The technical assignment of the technical problem to be solved in the present invention and proposition is the defective 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 potting in the husky ridge of the fixing potting formula sediment trapping net of husky ridge intermediate supports and job practices thereof.
The husky ridge of potting formula sediment trapping net, be with the mode of potting the sediment trapping net entirely potting in the middle of the husky ridge, constituted by sediment trapping net and the husky ridge; The husky ridge of this potting formula sediment trapping net can be on the desert interval 1m one rule proper alignment, be used for fixing the sand; Can construct at moving dunes top and artificial top of piling the check dam of building, be used for the intercepting desert.
The applicant has delivered " the fixing and utilizations of moving dunes " in 2009, in article, illustrated the principle on splayed net cage sand barrier fixed flow sand dune, illustrated simultaneously after the moving dunes top arranges splayed net cage sand barrier, because 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 the textbook are hindered 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, and H is the height of mechanical sand barrier, and a is the angle of cut.In (formula 2), V is the husky amount of resistance, and H is that the height .H1 of 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.Because splayed net cage sand barrier exposes the top of moving dunes less than 15cm, if apply mechanically the formula on the textbook, place the splayed net cage sand barrier at moving dunes top, it is very little hindering husky effect, but in fact expose top of sand dune less than the splayed net cage sand barrier of 15cm, owing to there are the moving dunes under the cylinder mould sand barrier to make liner, its hinder husky effect be higher than far away be arranged on the smooth desert, height is greater than the high vertical sediment trapping net of 150cm.Therefore (formula 1) is inapplicable in the husky effect of the resistance of the splayed net cage sand barrier at moving dunes top to constructing, and must just can say something with (formula 2).After the moving dunes top arranges splayed net cage sand barrier, tackled the drift sand that gets off by splayed net cage sand barrier 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 can't accomplish with the high vertical sediment trapping net that any method makes up.Thereby the function that has shown the efficient intercepting of moving dunes desert.But the mechanical sand barrier that so efficiently is easy to get on the desert also is not familiar with by people at present, fails so far to find in textbook correlation theory and experimental data.What introduce on the textbook is the waist that high vertical sand barrier is arranged on moving dunes, reaches the purpose of scabbling moving dunes, and people still process moving dunes as disaster so far.So the applicant is managing by engineering practice, prove that moving dunes are to be transformed into very convenient, very simply tall and big mechanical sand barrier.
The husky ridge of potting formula sediment trapping net and job practices thereof, the applicant from the fixing exploration job practices out the engineering practice of moving dunes of construction splayed net cage sand barrier, its effect of fixing moving dunes is identical with splayed net cage sand barrier, but material cost and construction cost decrease.
