Abstract

The invention provides an ecological protection structure of crushed rock side slope dry spray construction frame lattice beams and a base material and a method. The ecological protection structure ofthe crushed rock side slope dry spray construction frame lattice beams and the base material comprises an iron gauze laid on the whole slope surface, a short anchor rod for fixing the iron gauze, theframe lattice beams formed on the iron gauze by sand slurry spraying and a base material spraying layer, the base material spraying layer is located in a frame lattice formed by the frame lattice beams and the height of the base material spraying layer is lower than the height of the frame lattice beams, and the base material spraying layer comprises a base layer not containing mixing plant greenseeds and a surface layer containing the mixing plant green seeds; and the frame lattice beams with arc-shaped section profiles are fixed to the slope surface through a long anchor rod or a long anchor cable with an anchor head. According to the ecological protection structure of the crushed rock side slope dry spray construction frame lattice beams and the base material, frame lattice beam and plant cover shotcrete construction is completed by using a set of dry spray equipment, setting up of a scaffold and a template is removed, the construction process is simple and the construction periodis short, the construction cost is low, the ecological protection structure of the crushed rock side slope dry spray construction frame lattice beams and the base material is applied to slope protection and ecological remediation of the rock slope surface with the crushed slope surface and without deep landslide, and a wide application prospect is achieved.

Description

technical field [0001] The invention relates to an ecological protection structure and method for a frame beam and a base material of a broken rock slope by dry spraying construction, and belongs to the field of ecological slope protection. Background technique [0002] The ecological slope protection technology of sash beam filling can be used for both soil slopes and gentle rock slopes. The construction method is as follows: After finishing the slope, determine the position of the anchor bolt hole and set up scaffolding to prepare for drilling, after drilling and clearing the hole, insert the anchor bolt for grouting, excavate the trench, install steel bars and erect formwork to pour the frame Concrete the beams and maintain them, and finally fill the grid with soil to restore vegetation. This method has a good protective effect on the slope, and the greening effect is better when the slope is not large (the early water and soil loss is serious when the slope is too large...
