Abstract
The use of movable net grid mud intercepts dam is a new method in the living creature prevention and cure soil erosion. The main characteristic is to use the live tree stake, plait it to net grid, constituted from two net grids with same structure of the parallel alignment. Stuff with the egg stone and the coarse sand in it, thus the net grid dam can let the water that the earth's surface pathway flow seep out, but the mud is flow down. The purpose of prevention and cure soil erosion can be attained. It can raise a tree on the net grid; make it become the green hedge dam to keep the mud. In addition, it can intercept the mud effectively, it changes the sloping fields become the terraced fields gradually, solving the soil erosion thoroughly, and it has the ecosystem performance to make it green and beauful.
Description
Technical field:
Belong to water and soil conservation, interception earth is administered slight slope, erosion groove, the biological dam of prevention soil and water loss.
Background technology:
Current water and soil conservation, what extensively adopt is planting trees and grass.Because of general tree-planting method survival rate is low, so it is also slow to take effect.And growth is slow, and the time that closing are grown into forest long (10 years), this method just produces effect to the soil erosion on hillside.Show that according to pilot survey the silt of soil erosion 90% is directly from erosion groove.So water and soil conservation must ditch double the controlling in slope, and to control ditch be emphasis.The soil erosion of erosion groove is that erosion groove collapses along gravity dam takes place, and causes a large amount of earth to pile into bottom of trench.Earth bottom of trench when rainy season, mountain torrents attacked washes away, and bank continues avalanche afterwards, washes away once more.If things go on like this, erosion groove dashes wide more dark more more.So the soil erosion amount only increases.
Control ditch and adopt existing tree-planting method, because of the weight of trees can increase the avalanche of bank, so inapplicable, administering erosion groove, should to adopt new method to plant trees supporting with new dam, is only the effective ways of science.Dam has concrete (wall) or stone-laying (wall) earth dam etc.Preceding two kinds of cost height can not generally use, and beaver type timber dam is firm inadequately again.And the grid of living cut the mud dam, and are not only cheap firm again, and afforest and beautify the ecological benefits and the direct economic benefit of environment in addition.So be new technology advanced in the water and soil conservation.
Goal of the invention:
The soil is kept in the effectively preventing soil erosion.Both layed foundation, be descendants's peace of keeping tie of seeking survival again for current sustainable development.
Summary of the invention:
Adopt growth fast, germinating power is vigorous, and is suitable for the seeds (nursery stock) of local environment condition.Remove the seedling hat, only with the seedling stake that has root (the thick 5-8cm in footpath, high 1.4m), as figure (1), tiltedly plant and reticulate fence and (imbed 40cm in the soil, the 1m that is exposed, stub spacing 0.25-0.5m, in the fence mesh through 0.25-0.5m) the net grid of living cut the mud dam and are made up of with the fence of spline structure two rows, front and back fence spacing is 1-2m.Middle guanovulite and rough sand.
Effect:
This section mud dam can allow the seepage of surface flow walk, and the silt interception is lived.This fence can also germinate and trees, makes it to become netted section mud dam of hedgerow formula alive.So make the net grid of living cut the mud dam.His existing interception earth has the double action of greening environment again, can be widely used in the valley harnessing of water and soil conservation.
Description of drawings:
Figure (1) is arranged on the net grid alive that corrode the exit or entrance of a clitch and cuts mud dam schematic diagram.1, erosion groove edge; 2, the timber alive of band root (the thick 5-8cm in footpath, timber spacing 0.25-0.5m); 3, live cobble in the net grid; 4, the live diamond-shaped meshes of net grid.
5, the net grid of living cut the vertical view on mud dam.
Figure (2) adopts the net grid of living to cut the mud dam to carry out the double schematic diagram of controlling in ditch slope.Dam, three roads, the figure left side and twice dam, the upper right corner are section mud dam that is provided with along the hillside isohypse, the dam (this kind erosion groove at ordinary times be the hondo that do not have water, rainy season just have water by surface flow pass through) of the lower right corner for corroding the exit or entrance of a clitch.
Specific embodiments:
With the embodiment of bringing soil erosion under control, the effect that the net grid of living cut the mud dam is described in conjunction with the accompanying drawings.As figure (2), at the exit or entrance of a clitch of erosion groove and the slight slope of severe water and soil erosion, along isohypse net grid alive are set and cut the mud dam, be effectively to stop earth, the new method that prevents erosion.He not only can stop surface flow and wash away next earth, also can make the hillside gradually become terraced fields.The net grid of living till that time cut the mud dam just becomes the raised path through fields on terraced fields limit (will prune once every year, to keep the hedgerow shape).Germinating the tree that like this on fence has greening, the beautification function, also can raise fruit trees on terraced fields, economic plants such as medicinal material, so just can fundamentally solve the soil erosion problem of this area.
Claims (1)
- The net grid alive that are used for water and soil conservation cut the mud dam and concrete (wall) cuts the mud dam, masonry block (wall) cuts mud dam and earth dam ratio, and tangible advanced part is arranged.It is characterized in that: 1, use the stub alive of the same specification of two rows, be the netted paling form that rearranges and cut the mud dam.2, insert cobble or rough sand between two row's fence, the seepage of surface flow is walked, and the earth that runoff brings is stopped.3, can germinate from the fence and tree, what make it to become the hedgerow formula cuts the mud dam.Except that holding back the earth ecological benefits of afforesting and beautifying in addition.4, along with the growth of trees, the stub of forming the fence dam can be more and more sturdy, makes the effect that cuts the mud dam stronger, and prolong application life.5, this section mud dam can become terraced fields to the hillside fields gradually, and the net grid of living cut the biological net raised path through fields that the mud dam just becomes the work on terraced fields limit.
