Description
Technical field
The utility model relates to a kind of side slope ecological protection structure, particularly relates to the geotechnical grid structure that a kind of self-ignition coal gangue hill ecological management is special.
Background technology
In self-ignition coal gangue hill ecological management engineering, cover coal gangue hill surface with loess be a kind of simple economy and effective method.But the angle of repose of coal gangue hill is comparatively large, and the loose loess formation of covering is in unsteady state, very easily runs off.Its key problem in technology adopts compaction process to increase density of soil and stability, although be conducive to the growth that fireproof fire-extinguishing is unfavorable for plant, do not have vegetative coverage protect, loess formation still can produce erosion groove inefficacy.Effectively can solve by geotechnical grid technology and cover loess formation thickness and stability of foundation.
Geotechnical grid is by HDPE or the PP copolymerization material broadband of high strength, the netted lattice cell structure of a slice formed through brute force welding or riveted joint.It is capable of expansion and contraction, and can contract during transport gathers into folds, and opens and filling soil stone or concrete material again, form the structure with powerful lateral limitation and large rigidity during use.It can be used to as bed course, and soft ground treatment increases the supporting capacity of ground, also can be laid on domatic upper formation slope protection structure, can also be used to build retaining structure etc.But when common geotechnical grid is used for hillock such high gradient slope ecological management, seed and the table soil of outward opening easily run off, and the grid plan of lattice outside is unfavorable for taking other water-and-soil conservation measures.
In addition, when geotechnical grid common is at present used for high gradient slope ecological protection, although the lateral limitation of geotechnical grid is tried hard to keep hindered the substantially firm of domatic thickening soil moved in improve the original layer, but, the initial stage is completed in construction, the top layer seed of outward opening and soil are subject to erosion by wind and rain and run off, and produce sheet bald spot and fish-scale pit shape depression.Further, plant roots, stem degree of lignification are lower, and when branches and leaves coverage is not high, soil erosion can aggravate, and ecological revetment effect is had a greatly reduced quality.Further, the grid plan of lattice outside is unfavorable for taking other water-and-soil conservation measures.
On the other hand, vegetable fiber blanket significantly can reduce domatic topsoil erosion intensity, improves slope landscape, and promote vegetation recovery, more than 25 degree, soil erosion more than 70% can be reduced in abrupt slope.In principle, this technology is in line with the falling leaves settle on the roots, the theory of straw-returning, make full use of plant litter moisture holding capacity and organic with microorganism to the activation capacity of soil to improve the life condition of plant seedling, soil moisture conservation weighing apparatus temperature.But vegetable fiber blanket mechanical strength is lower, the bearing down of thick soil moved in improve the original layer at slope descent cannot be born, cause vegetable fiber blanket to be easy to damaged.
