Slope support system and construction method

Abstract

The invention relates to a slope support system which comprises traction ropes, soil nails and a plurality of bearing networks, wherein at least four connecting buckles are uniformly distributed on the side surface of each of the bearing networks around the axis of the bearing network; every two adjacent bearing networks are connected through at least one traction rope; at least two connecting sliding chutes are formed in the lower end face of each of the bearing networks; the rear end faces of the bearing networks are connected with at least four soil nails through the connecting sliding chutes; and the soil nails are distributed around the axes of the bearing networks and are perpendicular to the rear end faces of the bearing networks. A support method comprises four steps of collectingconstruction parameters, positioning the soil nails, positioning the bearing networks, and curing gunite. According to the slope support system, on one hand, the demand for fixing a mountain body, a dam and a foundation pit side wall is met, on the other hand, the construction efficiency can be effectively improved, and moreover, the positioning structure and the protective strength of a support working face can be improved, and the positioning stability and reliability of the slope support system in a geologic structure are improved.

Description

technical field [0001] The invention relates to a side slope support system and a construction method, belonging to the technical field of civil engineering equipment. Background technique [0002] At present, in the strengthening and fixing construction of slopes such as mountains, dams and building foundation pits, concrete slurry is often sprayed on the construction work surface, but on the one hand, due to the fluidity of the concrete slurry itself, it is easy to cause it to change from The support work surface fell off, which seriously affected the construction efficiency and caused a lot of waste of resources. On the other hand, due to the huge difference between the concrete and the work surface to be protected, the sprayed layer and the construction work surface after the spraying were completed The strength and stability of the connection structure are relatively poor, which cannot effectively meet the needs of actual use. [0003] In response to this problem, the ...

[0002] At present, in the strengthening and fixing construction of slopes such as mountains, dams and building foundation pits, concrete slurry is often sprayed on the construction work surface, but on the one hand, due to the fluidity of the concrete slurry itself, it is easy to cause it to change from The support work surface fell off, which seriously affected the construction efficiency and caused a lot of waste of resources. On the other hand, due to the huge difference between the concrete and the work surface to be protected, the sprayed layer and the construction work surface after the spraying were completed The strength and stability of the connection structure are relatively poor, which cannot effectively meet the needs of actual use

[0003] In response to this problem, the current main method is to first drive a large number of anchor rods on the construction work surface, and then connect the anchor rods through steel strands, etc., so that the load-bearing structure distributed in the network structure on the support work surface , although the construction efficiency and quality have been improved to a certain extent, but the use of anchor bolts is huge, the strength and difficulty of use are high, and the construction efficiency is low, and the traditional anchor bolt construction method also leads to relatively low positioning stability between the anchor bolt and the construction work surface. Poor, so it is still difficult to effectively meet the needs of actual construction operations
