Background technology
Karst landform is meant that the solubility rock receives the corrosion of water and the formed various landforms of following of mechanism, extensively is distributed with karst landform on Guangxi of China, Guizhou, Yunnan and other places.In recent years,, cause karst landform to form a large amount of bare side slopings along with large-scale engineering construction and mining, produced in a large number can't restore vegetation rock slope, cover in its surperficial natural restore vegetation in a short time and possibly realize hardly; Existing slope project reinforcement measure is pursued the intensity effect more, adopts grey protection such as stone-laying and pneumatically placed concrete mostly, has destroyed the harmony of natural, ecological like this.Along with people's is to the attention of ecological environmental protection and the further increase of China's economic strength; The slope vegetation protection engineering also has been applied in the middle of the engineering construction gradually; Existing application adopts the explosion afforestation method more, and the method is not suitable for karst landform, or on rock slope, adopts stone-laying it to be fixed and is divided into little lattice making earlier and plant living member; Then the native cultural vegetation of the little lattice interplantation of its division; Though such slope vegetation protection engineering has certain afforestation effect, but can't satisfy ecological harmony property, artificial vestige is too obvious.Mostly existing manual greening side slope re-engineering is to the stone matter side slope of the gradient less than 75 °; When stone matter grade of side slope during less than 75 °; Two patents that the applicant applied for respectively on May 8th, 2009 " a kind of shrub slope protection that is arranged on the karst area slope is planted living member " and " be arranged on the karst area slope side slope shrub slope protection with T type plate from plant wastes " all can reach artificial soil adhesive rate preferably, can well accomplish greening vegetation regeneration in several years after construction; But in the face of stone matter side slope complex changeable characteristics, regular meeting runs into the stone matter side slope greater than 75 ° even 90 ° in work progress, runs into to the class side slope; Also there is not good solution at present; Common methods is that stone matter side slope is cleared up again, and its gradient is diminished, but this method construction volume is very big; Time cycle is long, and dangerous.
Summary of the invention
The technical problem that the utility model will solve is; Provide that a kind of construction volume is little, the cycle is short; Cost low can the gradient accomplish on greater than 75 ° stone matter side slope artificial vegetation's regeneration to the stone matter side slope nursing structure of the gradient greater than 75 °,, can overcome the deficiency of prior art.
The technical scheme of the utility model; Greater than 75 ° stone matter side slope nursing structure, it comprises that the gradient greater than 75 ° stone matter side slope, is connected with the plate from plant wastes that is 25 °~45 with the gradient on stone matter side slope to the gradient, and plate from plant wastes is planted living groove with stone matter side slope formation.
On stone matter side slope, be connected with the gradient and be 25 °~45 ° anchoring rod pieces, plate from plant wastes (2) is connected on the anchoring rod piece.
Plate from plant wastes is a cast in place concrete plate, and cast in place concrete plate is the cast in place concrete plate of muscle with the anchoring piece.
The width of plate from plant wastes is 200mm~800mm, and thickness is 15mm~30mm.
On plate from plant wastes, offer water falling hole, the aperture of water falling hole is 50mm-150mm.
The line space of planting living groove is 1500~3000mm.
Realize by following steps greater than the method for arranging of 75 ° stone matter side slope nursing structure to the gradient:
A, elder generation hole greater than the domatic 25 °~45 degree that is of 75 ° stone matter side slope in the gradient, squeeze into anchoring rod piece again, with injecting paste material anchoring rod piece are reinforced;
B, choose template, be fixed on about the anchoring rod piece template proximate is domatic, anchoring piece is clipped in wherein, be fixed on about the anchoring rod piece with the galvanized wire colligation; The template width is 200mm~800mm,, length is looked the side slope situation and is carried out dynamic design, and thickness is 5mm~15mm;
C, the concrete casting that stirs is filled in template and the anchoring piece interlayer, and makes it to tamp as far as possible.
Before concreting, place the leaking hole mould on the template now, the diameter of leaking hole mould is 50mm-100mm.
Compare with prior art; The utility model is to the stone matter side slope of the gradient greater than 75 °; Through on the stone matter side slope of heavy grade, building big plate from plant wastes, make between plate from plant wastes and the stone slope constitute one can a large amount of artificial soils of splendid attire plant living groove, for artificial soil and seed provide one well to adhere to flat upper surface; The expansion of root system during with better assurance plant growing is for the growth of vegetation is laid a solid foundation.Fixing anchoring rod piece on stone matter side slope earlier when making up plate from plant wastes; Can improve the bearing strength of planting living groove like this; Increase its stability, just can guarantee that soil can not run off planting under the situation that living groove do not collapse, just can well platform be provided for the germination of seed.The preferred concrete cast-in-place slab of plate from plant wastes, concrete cast-in-place slab are the corrosion that muscle can reduce anchoring piece greatly with the fixed anchors, can guarantee that like this it has enough supporting capacitys, make things convenient for field construction simultaneously and draw materials.The width of cast in place concrete plate and plant interval between the living groove and be in applicant's long-term work and sum up gained; The soil amount of splendid attire can make vegetation fully grown in this width; At a distance from interior vegetation after the growth is covered rock slope during this time; On plate from plant wastes, offer water falling hole, it is identical that this principle and flowerpot are offered the leaking hole principle.Test according to the applicant; Find obviously to reduce the difficulty of the artificial bank protection of heavy grade with the utility model; And the vegetation response rate is very high, and the utility model also has advantages such as simple in structure, that greening speed is fast, cost is low simultaneously, and excellent popularization and practical value are arranged.

The specific embodiment
Embodiment: as shown in Figure 1; What the utility model was directed against is that the gradient is nursed greater than 75 ° stone matter side slope; It is to hole greater than the domatic 25 °~45 degree that is of 75 ° stone matter side slope 1 in the gradient, in institute's perforate, squeezes into anchoring rod piece 4 again, and with injecting paste material anchoring rod piece 4 is reinforced.Choose template after installing anchoring rod piece 4, the domatic anchoring rod piece that is fixed in of template proximate about in the of 4, is fixed on the anchoring rod piece 4 with the galvanized wire colligation; The template width is preferably 200mm~800mm, and length is looked the situation of stone matter side slope 1 and carried out dynamic design, and thickness is preferably 5mm~10mm; The concrete casting that stirs is filled in the template, and makes it to tamp as far as possible, promptly form the plate from plant wastes 2 by the cast-in-situ concrete board member behind dried the consolidating, the thickness of plate from plant wastes 2 is 15mm~30mm; Plate from plant wastes 2 constitutes with stone matter side slope 1 plants living groove 3.Before concreting, place the leaking hole mould on the template now, pound out mould behind dried the consolidating, the aperture of the water falling hole 5 of formation is 50mm-100mm.The line space of planting living groove 3 is 1500~3000mm, and it is fixed specifically to come according to selected vegetation.
