Abstract

The invention provides a device for expanding the range of grouting reinforcement. It includes a grouting pipe, a grouting barrel and a grouting valve; the bottom of the grouting barrel is provided with a bottom plate and a top plate, and the bottom plate, the top plate and the side walls of the grouting barrel form a grout containing chamber; one end of the grouting pipe passing through the top plate; the side wall of the accommodating cavity is slidably connected with the grouting valve; the grouting valve includes an outer sleeve, an interlayer sleeve assembly and an inner drilling core which are sequentially nested and slidably connected along the axial direction. The invention expands the radius of the grouting range of the grouting equipment by installing a telescopic grouting valve on the side wall of the grouting barrel, reduces the drilling density of the grouting holes, reduces the drilling workload of the construction personnel, and at the same time expands the grouting range radius of the grouting equipment. The expansion and contraction of the grouting valve can be realized only by adjusting the grouting pressure, and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of stratum grouting reinforcement, in particular to a device for expanding the range of grouting reinforcement. Background technique [0002] Karst, also known as karst, is characterized by the chemical corrosion of water on soluble rocks (calcium carbonate, sulfate, halogen rock, etc.), and includes the mechanical erosion and collapse of water, as well as the carrying out, transfer and redeposition of substances. A collective term for comprehensive geological processes and the phenomena that result from such processes. [0003] The karst area is a geological disaster area, and there are a large number of dissolved soil caves underground. For the excavation of pile foundations, foundation pits, and underground tunnels, it is necessary to pre-treat the dissolved soil caves to ensure construction and operation safety and avoid dissolved soils. Caves induce safety accidents such as hole collapse, water leakage...
