Self-grouting-stopping device of assembly type grouting guiding pipe

Abstract

The invention provides a self-grouting-stopping device of an assembly type grouting guiding pipe,and belongs to the technical field of geotechnical engineering and particularly belongs to undergroundconstruction guiding pipe grouting construction. The self-grouting-stopping device of the assembly type grouting guiding pipe comprises a grouting guiding pipe, a sleeving pipe, a sealing ring, a check plug and a grouting connecting pipe, wherein a separating grid is arranged on a slurry inlet of the grouting guiding pipe, outer threads are arranged on the outer wall of the slurry inlet, a ring-shaped sealing plate is arranged at the inlet end of the sleeving pipe, a ring-shaped groove is formed in the inner wall of the outlet end, the ring-shaped groove is provided with inner threads, the sealing ring is arranged between the end surface of the ring-shaped groove and the end surface of the slurry inlet of the grouting guiding pipe, the grouting connecting plate is fixed to the sealing plate, and the check plug is a cone and is arranged in the sleeving pipe and the grouting connecting pipe. According to the self-grouting-stopping device of the assembly type grouting guiding pipe, the grouting guiding pipe, the sleeving pipe, the check plug and the grouting connecting pipe are all prefabricated by a factory and can be quickly assembled and used in an engineering field, a grouting andgrout-stopping device is not required to be machined on the construction site, site operating time is shortened, and potential safety hazards caused by electrical welding or cutting operation are avoided.

Description

Technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to the pipe grouting construction of underground engineering, in particular to an assembled grouting pipe self-stopping device. Background technique [0002] With the rapid economic development, the construction scale of geotechnical engineering including underground engineering is expanding day by day. In the process of geotechnical engineering construction, there are often problems of weak rock and soil or groundwater seepage or even gushing (such as rock and soil reinforcement or water stop in slopes, foundation pits, tunnels, subways, mining and other underground chambers), usually Conduit grouting is used to reinforce rock and soil or block groundwater. [0003] The traditional pipe grouting method needs to process the grouting grouting device on the project site, such as welding and connecting the steel pipe and the switch gate valve between the end of the pipe and ...
