Abstract
The invention provides a parallel construction method for slope protection anti-erosion ecological blanks and a slope protection structure. The construction method comprises the steps of 1) slope surface setting; 2) field data measurement; 3) anti-erosion ecological blank laying along the direction parallel to the road or a river; 4) comprehensive fixation of the two adjacent anti-erosion ecological blanks through a lapping seaming and fixing nail fixing mode; 5) earthing the surfaces of the anti-erosion ecological blanks; 6) plant conservation. The slope surface protection structure comprises the anti-erosion ecological blanks laid along the direction parallel to the road or river slope surface, the two adjacent anti-erosion ecological blanks are in lapping connection, seamed and fixed through the fixing nails, two ends of the anti-erosion ecological blanks are fixed through anchor rods, ditches are dug at the bottoms of the top and bottom anti-erosion ecological blanks, composite fiber fabric layers are arranged at the positions in the ditches, which are close to the anti-erosion ecological blanks and are compressed through gabions, and the anti-erosion ecological blanks and the pre-buried composite fiber fabric layers are seamed through lines. By the aid of the construction method, the anti-erosion capacity of the anti-erosion ecological blanks is greatly improved, water and soil loss is prevented, the slope is stabilized, and ecological restoration is achieved.
Description
(1) technical field
The present invention relates to the construction method of a kind of highway, Channel slope protector, specifically parallel construction method and the slope protection structure of the ecological blanket of a kind of bank protection anti-impact.
(2) background technology
Side slope is the important component part in highway, river course, deals with improperly, easily occurs brokenly to fall, avalanche, slump even come down, both welding, affect highway again, river course normally moves, and interruption of communication when serious, affects the normal flood passage flood discharge in river course, causes heavy economic losses.In order to guarantee roadbed, channel revetment stability of slope, prevent slope body sloughing and slope erosion, brokenly fall, need to take rationally suitable engineering measure, as built the supporting construction that bears native stone pressure, or carrying out slope protection, native stone pressure is not born or is not substantially born in this protection.
The ecological blanket of anti-impact is a kind of novel slop protection material, it is by composite fiber fabric, anti-filter nonwoven, the supporting integrated novel ecological slope protection materials such as variation grass seeds, fertilizer layer and degradable fabric, when preventing side slope embankment water erosion, soil losses, can reach the effect of slope ecological reparation, landscape planting.
The now domestic use to the ecological blanket of anti-impact is perpendicular to the direction in highway or river course, lays the ecological blanket of anti-impact on smooth side slope surface, and the joining place of the ecological blanket of anti-impact is to fix with ABS staple, and at the top layer earthing 2～4cm of anti-impact ecology blanket.Actual engineering experience proves: when drag force is larger, the ecological blanket of anti-impact of laying the joining place of the ecological blanket of anti-impact perpendicular to highway or river course easily washes away, grass seeds in it and the earthing on fertilizer and top layer also wash away thereupon, cause the survival rate of vegetable seeds low; Or arid is without rain for a long time, and seed cannot survive, and final result is that plant survival rate is low, cannot reach the effect of greening side slope, ecological recovery.
(3) summary of the invention
Technical assignment of the present invention is for the deficiencies in the prior art, and parallel construction method and the slope protection structure of the ecological blanket of a kind of bank protection anti-impact is provided.
The technical solution adopted for the present invention to solve the technical problems is:

1) slope control: domatic obstruction, the foreign material that construction is hindered in highway to be onstructed or river course are cleaned out to infrastructure device compacting.
2) measure field data: what side slope protection was carried out in scene domaticly does detailed data mapping and calculating, in order to select the ecological blanket of anti-impact of certain width.
3) along the direction that is parallel to highway or river course, lay the ecological blanket of anti-impact; At the both ends of laying the ecological blanket of anti-impact, adopt anchor pole to fix, first the top with below the ecological blanket of anti-impact below ditching, then with lattice guest gabion, press one deck composite fiber fabric layer, the ecological blanket of anti-impact and reserved composite fiber fabric layer suturing with thread management.
4) between the ecological blanket of adjacent two anti-impacts, adopt the mode that overlap joint is sewed up and staple is fixing comprehensively fixing;
5) the ecological blanket of anti-impact surface earthing, at the ecological blanket top layer earthing 2～4cm of anti-impact, then lays woven straw;
6) plant maintenance: after having laid, carry out in time water seasoning, guarantee that whole side slope surface keeps certain wettability, evenly scatters to domatic with spray gun special when plant maintenance waters.
The ecological blanket of described anti-impact is from top to bottom composite fiber fabric layer, loaded filter, grass seeds and fertilizer layer, the combination of biodegradable fiber layer successively.
The width of the ecological blanket of anti-impact is 0.4～6m.
It is a kind of that to take the ecological blanket of anti-impact be basic slope protection structure, comprise along the ecological blanket of anti-impact that is parallel to the domatic laying in highway or river course, between the ecological blanket of adjacent two anti-impacts, overlapping the slot merging is fixed with staple, the two ends of the ecological blanket of anti-impact adopt anchor pole to fix, be positioned at the top and below the ecological blanket of anti-impact dug groove below, position near the ecological blanket of anti-impact in groove is equipped with one deck composite fiber fabric layer, in groove, be filled with lattice guest gabion composite fiber fabric lamination is tight, the ecological blanket of anti-impact and pre-buried composite fiber fabric layer suturing with thread management.
The packing density of described anchor pole and length determine as calculated afterwards according to the actual conditions of local soil.
The suturing with thread management link of non-degradation of fibers fabric for the ecological blanket of described anti-impact and Ge Bin gabion joining place.
Compared with prior art, the beneficial effect producing is for the parallel construction method of the ecological blanket of a kind of bank protection anti-impact of the present invention and slope protection structure:
Construction method of the present invention greatly improve the erosion resistibility of the ecological blanket of anti-impact, the conservation of soil and water, stable side slope, recovers ecological; The growth that fertilizer layer in the ecological blanket of anti-impact is plant provides nutriment.
