Description
Technical field
The present invention relates to a kind of combined type sand-protecting barrier, belong to environmental and ecological protection technical field, particularly in control of desert engineering, vertical type sand-protecting barrier arranges technical scope.
Background technology
Desertification is one of current ecological problem the most serious in the whole world.Current global Desertification Soil area is 3,600 ten thousand square kilometres, and 1/4th of Global land area is subjected to desertification and threatens, and the population in the whole world 1/5th is subject to desertification impact.China is one of country that ccd area is large, distribution is wide, harm is heavy in the world, Xinjiang, Gansu, Ningxia, Inner Mongol Deng Shi China sandy desertification area are maximum, distribution is the widest, harm is the most serious several provinces and regions, the diastrous weather such as western many counties and cities strong wind in every spring, floating dust, sand, sandstorm is frequent, and arable land, grassland, forest land, settlement, road etc. are attacked by dust storm often.People are larger by the impact of sandstorm, desertification serious threat and govern ecological safety and the socio-economic development of China, and jeopardize the sustainable development of east China district setting quality and economic society, threaten the survival and development of the Chinese nation, but in the long term, the harm of movement to human survival on sand dune is even more serious.
Control of desert is a comprehensive system engineering, and the key project technical measures of defending and controlling sand are fixed the sand and hinder sand, namely fixes the sandy soil particle in earth's surface sandy soil particle and interception sand and dust, makes desert reduce flowing as far as possible; In long-term control of desert process, the Engineering of sand control technical measures obtaining having practical value are vertical type sand-protecting barrier, wherein: the vertical type sand-protecting barriers such as checked sand hinder straws, constructional materials sand-protecting barrier are auxiliary combined method of defending and controlling sand to hinder Sha Weizhu, to fix the sand, have and gather materials on the spot, resource reutilization, environmental protection, fix the sand to hinder husky double effects advantage and be widely applied.
For the complexity of the western desertification process of China, the diversity of type, the popularity of distribution, the seriousness of harm and the urgency of control, also use for reference on the basis of existing related ends at the space distribution rule of scientific analysis desertification occurrence condition and current situation, inquire into and a kind ofly hinder sand bar and checked sand hinder straws arrangement and formed there is the control of desert pattern of combined type, resistance sand bar major function stops sand dune flowing, earth's surface wind speed can be weakened simultaneously, checked sand hinder straws realizes checking winds and fixing drifting sand by the sandy soil particle in fixing earth's surface sandy soil particle and interception sand and dust, the control of desert pattern of this combined type serves and stops sand dune flowing, the effect of checking winds and fixing drifting sand, can protecting ecology, change people's living environment, to the positive practical significance of defending and controlling sand promoting China.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of combined type sand-protecting barrier, adopting resistance sand bar and checked sand hinder straws arranged to form combined type sand-protecting barrier, for stopping sand dune flowing, checking winds and fixing drifting sand, realizing the sand control effect of comprehensive high-efficiency.
The technical solution adopted in the present invention comprises: the checked sand hinder straws laid by certain area, around checked sand hinder straws, be provided with section is trapezoidal resistance sand bar, resistance sand bar around checked sand hinder straws linearly, interval multirow is staggered and is combined to form combined type sand-protecting barrier, stop to flow in sand dune by resistance sand bar, fix the sandy soil particle in earth's surface sandy soil particle and interception sand and dust by checked sand hinder straws, combined type sand-protecting barrier realizes comprehensive sand control function.
In described combined type sand-protecting barrier, checked sand hinder straws height h, resistance sand bar section isosceles trapezoid base angle a, lower bottom width b, height of dam c, dam length d, wherein: base angle a is less than the angle of repose of resistance sand bar constructional materials used, height of dam c >=2h, lower bottom width b > 2c/tan (a), dam length d > b, resistance sand bar linear array interval e < d, line-spacing f > 2b, resistance sand bar is 2 ~ 4 row along linear array line number around checked sand hinder straws.
In described combined type sand-protecting barrier, checked sand hinder straws material and laying are required to carry out selection and laying according to existing prior art standard, resistance sand bar adopts the sandy soil of operation field to be piled into trapezoidal cross-section body, again by physics or chemical method to resistance sand bar surface Hardening Treatment windward, to strengthen the Resistance to wind Erosion of resistance sand bar.
Above-mentioned combined type sand-protecting barrier aligning method in desert is, combined type sand-protecting barrier is by sequentially extending arrangement in length and breadth, and adjacent two combined type sand-protecting barriers share same group of resistance sand bar.
Compared with prior art, beneficial effect of the present invention is, by the combined type sand-protecting barrier that resistance sand bar and checked sand hinder straws permutation and combination are formed, the sandy soil particle in earth's surface sandy soil particle and interception sand and dust is fixed by checked sand hinder straws, stop to flow in sand dune by resistance sand bar, combined type sand-protecting barrier has the sand control effect of comprehensive high-efficiency in control of desert, has the function weakening earth's surface wind speed and extend checked sand hinder straws application life simultaneously.
Accompanying drawing explanation
Fig. 1 is combined type sand-protecting barrier theory of constitution figure;
Fig. 2 is combined type sand-protecting barrier arrangement design sketch.
Detailed description of the invention
With reference to the accompanying drawings embodiments of the invention are described below.
