The invention discloses a kind of devices for loess slope slope greening, by collecting rainy season precipitation and being stored in round header tank, are that slope plants slowly, constantly supply water using siphonage, reach slope greening effect.The device is by round header tank, cover board, geotextiles, water guide body, siphon tube bank composition, in embedding one round header tank of every slope ditch, round header tank opening places cover board, a circular hole is arranged in cover plate central, cover plate central is recessed, one layer of geotextiles are laid with above cover board, water guide body is placed above geotextiles, the structure of water guide body is that geotextiles wrap up sand, a trepanning is arranged in round header tank side wall, the water inlet of siphon tube bank extend into the bottom of round header tank, siphon tube bank is reached across the trepanning of round header tank side wall outside round header tank, the water outlet of siphon pipe is inserted in the soil body near slope plants root system.Whole device not only exempts from power water supply, is also equipped with dredging effect, continually and steadily.

Description

A kind of device for loess slope slope greening
Technical field
The invention belongs to geotechnical engineering field more particularly to a kind of devices for loess slope slope greening.
Background technology
China possesses is distributed most concentration and the maximum Canal in Loess Area of area in the world, and Canal in Loess Area vegetation is rare, and summer is more Heavy rain, loosing soil, loess slope easily corrodes by rainwater for a long time, severe water and soil erosion, forms the terrain environment of ravines and guillies criss-cross, leads The problems such as cause Cultivated Land Area Decrease, river load content increases.
It is a kind of cost-effective means to improve loess slope vegetation coverage, and vegetation not only has the conservation of soil and water Effect, and the effect of the anchoring reinforcement of vegetation root system has both raising slope texture, and this method is used by a large amount of engineering. However, Canal in Loess Area rainfall is small and concentrates, evaporation capacity is big, and vegetation is difficult survival under conditions of water shortage when dry season, therefore is reached Less than afforestation effect.Accordingly, it needs to explore the greening that a kind of technological means efficiently, easy, economic improves loess slope slope surface Effect.
Invention content
The present invention solves slope plants because dry season water shortage can not be grown, to increase slope surface for the problem that Canal in Loess Area Vegetation coverage, effective conservation of soil and water.
The technical scheme is that:A kind of device for loess slope slope greening, the device by round header tank, Cover board, geotextiles, water guide body, siphon tube bank composition, in embedding one round header tank of every slope ditch, round header tank opening Cover board is placed, a circular hole is arranged in cover plate central, and cover plate central is recessed, and one layer of geotextiles, geotextiles top are laid with above cover board Water guide body is placed, the structure of water guide body is that geotextiles wrap up sand, and a trepanning is arranged in round header tank side wall, siphon tube bank Water inlet extend into the bottom of round header tank, and siphon tube bank reaches round header tank across the trepanning of round header tank side wall Outside, the elevation of siphon tube bank peak is less than the elevation of cover board, and the siphon pipe group by multiple a diameter of 1mm-2mm is restrained in siphon At, siphon pipe material is that PU is managed or PA pipes, siphon tube bank are dispersed into each independent siphon pipe after reaching outside round header tank, The water outlet of siphon pipe is inserted in the soil body near slope plants root system.
When rainy season arrives, in Po Gouchu, water oozes the runoff gathering that rainfall is formed under flowing through after water guide body, again passes through geotechnique Then cloth is flowed into from the circular hole on cover board in round header tank, the water level in round header tank rises to certain altitude, and siphon is made With startup, siphon pipe is that the root system of plant in slope surface slowly, continuously supplies water, and improves the survival of the plant in slope surface Rate reaches the afforestation effect of slope surface.
Advantages of the present invention is as follows.
1. round header tank is embedded in the soil body, opening sealing, evaporation capacity is small, and the water being collected into not easily runs off, and reduces simultaneously Slope ditch runoff washes away slopes.
2. being that slope plants root system supplies water with siphon principle, it is that a kind of flow and flow process are become by water level that siphon, which is supplied water, Change the system automatically controlled, has the characteristics that exempting from power realizes water body efficiently across transmission, the length by increasing siphon pipe can Think the phytoremediation farther out apart from slope ditch.
3. the mode that siphon is supplied water is slowly and continual and steady, it ensure that a rainfall catchments and can supply water the several months.
4. whole device increases with usage time, fine grained soil can enter in round header tank and deposit, but siphon Fine grained soil can be sucked out in effect, ensure that whole device continuously and effectively plays a role.
Description of the drawings
Fig. 1 is look down on the rendering of the present invention.
Fig. 2 is the present invention along the sectional view perpendicular to the direction that side slope is moved towards.
In figure, 1 round header tank, 2 cover boards, 3 circular holes, 4 geotextiles, 5 water guide bodies, 6 trepannings, 7 siphons tube bank, 8 siphon pipes, 9 plants, 10 slope ditches, 11 slope surfaces.
Specific implementation mode
Invention is further described in detail in the following with reference to the drawings and specific embodiments, and the objects and effects of the present invention will It is more obvious.
As shown in Figs. 1-2, a kind of device for loess slope slope greening provided by the invention, the device are collected by circle Water tank 1, cover board 2, geotextiles 4, water guide body 5,7 composition of siphon tube bank, in every round header tank 1 of 10 embedding one, slope ditch, circle 1 opening of shape header tank places cover board 2, and 2 centrally disposed circular holes 3 of cover board, 2 central dip of cover board, 2 top of cover board is laid with one Water guide body 5 is placed in layer geotextiles 4,4 top of geotextiles, and the structure of water guide body 5 is that geotextiles wrap up sand, 1 side of round header tank A trepanning 6 is arranged in wall, and the water inlet of siphon tube bank 7 extend into the bottom of round header tank 1, and siphon tube bank 7 passes through round collection The trepanning 6 of 1 side wall of water tank reaches outside round header tank 1, and elevation of the elevation less than cover board 2 of 7 peaks, siphon are restrained in siphon Tube bank 7 is made of the siphon pipe 8 of multiple a diameter of 1mm-2mm, and 8 material of siphon pipe is that PU is managed or PA pipes, siphon tube bank 7 reach It is dispersed into each independent siphon pipe 8 after round header tank 1 is outer, the water outlet of siphon pipe 8 is inserted near 9 root system of slope plants In the soil body.
When rainy season arrives, at slope ditch 10, water oozes the runoff gathering that rainfall is formed under flowing through after water guide body 5, again passes through Then geotextiles 4 are flowed into from the circular hole 3 on cover board 2 in round header tank 1, the water level in round header tank 1 rises to certain height Degree, siphonage start, and siphon pipe is that the root system of plant 9 in slope surface 11 slowly, continuously supplies water, and is improved in slope surface 11 Plant 9 survival rate, reach the afforestation effect of slope surface 11.
