Problems solved by technology
Anchor grouting fills and reinforces the joints and fissures of the rock mass within a certain range of the anchor and applies prestress to the rock mass to increase the shear strength of the rock mass and ensure the stability of the slope. However, the reinforcement range of the anchor grouting is small. Due to the limited range of support, it is impossible to effectively reinforce the broken rock mass of the rock slope and improve the anti-seepage performance of the broken rock mass of the rock slope
[0004] To sum up, for the problems existing in the treatment of broken rock mass in related technologies, no effective solutions have been proposed so far

Embodiment 1
[0040] Embodiment 1: A steel wire grid net protection structure for broken rock mass of a rock slope, which reinforces the broken rock mass 2 on the rock slope 1, including a system anchor rod 11, a prefabricated plate 14, and a grouting pipe 16, Among them, the system anchor 11 is arranged on the rock slope 1, and the prefabricated plate 14 is fitted on the rock slope 1 through the system anchor 11, and its upper and lower sides are fixed to the rock slope 1 by the anchor plate 15. A grouting hole 13 and a grouting pipe 16 extending into the grouting hole 13 are arranged on the plate 14 . Specifically, the prefabricated slab 14 is fixed to the rock slope 1 through the system bolts 11 arranged in an array on the rock slope 1, and the grouting holes 13 are set on the prefabricated slab 14, and the grouting pipe 16 is used to feed the broken rock mass. 2 Inject grout 10 to reinforce the area of the broken rock mass 2.

The invention discloses a rock slope broken rock mass steel wire grating net protection and a construction method. The construction method comprises the following steps of pulling prefabricated slabsthrough anchor rods, then grouting and reinforcing broken rock mass, paving a steel wire grating net outside the rock slope broken rock mass so as to seal the broken rock mass, coating an impermeablegeomembrane outside the steel wire grating net, pulling the steel wire grating net through the anchor rods, arranging a temporary flattening frame outside the impermeable geomembrane for flattening, and grouting the impermeable geomembrane, wherein a movable scaffold operation platform is adopted in a construction process, the upper part of the operation platform is pulled through anchoring piles,and a slope toe on the lower part of the operation platform is anchored. According to the protection and construction method, the rock slope broken rock mass can be effectively reinforced, the construction difficulty of the rock slope broken rock mass protection is reduced, and the anti-seepage performance of the rock slope broken rock mass is improved.
Description
technical field [0001] The present invention relates to the field of civil engineering, and more specifically relates to the protection and construction method of steel wire grid nets for broken rock masses of rocky slopes. Background technique [0002] Broken rock treatment has always been an unavoidable technical problem in slope treatment construction. In actual engineering, due to the broken rock mass formed by geological structure, primary cracks and human influence, the mechanical properties of the broken rock mass are very weak, and the existence of the broken rock mass seriously destroys the continuity and integrity of the rock mass, greatly changing the The mechanical properties of rock mass often bring hidden dangers to projects such as dams, slopes and underground chambers, and lead to instability and destruction of engineering rock mass. In addition, rock mass strength prediction, rock slope stability analysis, and bedrock bearing capacity determination in geolo...
