Prefabricated part mortise grouting device for assembly type subway station and using method

Abstract

The invention relates to a prefabricated part mortise grouting device for an assembly type subway station. The grouting device comprises a slurry feeding pipe, one end of the slurry feeding pipe is connected with a slurry jacking and pipe winding all-in-one machine, the other end of the slurry feeding pipe is connected with one end of a self-locking grouting pipe through a pressurizing mechanism, one side of the slurry jacking and pipe winding all-in-one machine is connected with a cleaning type wire arranging device through a synchronous transmission mechanism, and the slurry feeding pipe is arranged on the cleaning type wire arranging device in a penetrating mode. According to the grouting device, the grouting power function, the winding and unwinding pipe release function and the moving function can be combined into a whole through the slurry jacking and pipe winding all-in-one machine, the device can move more flexibly on a construction site, and a grouting pipe can be automatically stored by means of the winding and unwinding pipe release function; the grouting pressure can be greatly improved by additionally arranging the pressurizing mechanism at the end of the slurry feeding pipe, and the grouting function is stabler; and the self-locking grouting pipe can be automatically clamped in a grouting groove hole, connection between the self-locking grouting pipe and the grouting groove hole is stabler and more convenient, and the stability of the grouting process can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of prefabricated subway station construction devices, in particular to a prefabricated component tongue and groove grouting device for an assembled subway station and a method for using it. Background technique [0002] The subway station is composed of platform floor, station hall floor, equipment floor and entrances and exits. According to the distribution of lines, the subway platform can be divided into: island platform, side platform and mixed platform, which are used for passengers to take off, transfer and wait. The site should ensure that passengers can enter and exit the station conveniently, safely and quickly, and have good ventilation, lighting, sanitation, fire prevention equipment, etc., to provide passengers with a comfortable and clean environment; the prefabricated station is built by "building blocks" The main structure prefabricated in the factory will be transported to the construction si...

Problems solved by technology

[0004] First, after the splicing of the prefabricated components of the prefabricated subway station is completed, it is necessary to inject grout into the tongue and groove of the splicing place to seal the splicing gap. The splicing gap of prefabricated components is generally small and the grouting pressure is high. During the grouting process, for It is easy to operate, and the grouting conveying pipe will be stretched for a long distance. The longer the pipe, the more the internal slurry will be, and the greater the resistance will be. When grouting to the top of the subway station, the grouting equipment needs to be lifted vertically to convey the slurry. The grouting equipment not only needs to withstand the pressure of grouting into the gap, but also bears the resistance of the grout in the pipe itself. In the existing equipment, when the grouting delivery pipe is long, the grout pressure will be insufficient and it will be difficult to fill the tenon and groove Situation in the gap

[0005] Second, during the grouting process, the grouting head needs to be connected with the prefabricated grouting slot hole. Due to construction and production errors, there will be incomplete matching between the grouting slot hole and the grouting head, which will cause the injected grout The material overflows and leaks around the grouting slot hole

[0006] Third, in the grouting process, in order to ensure the stable injection of the grout, the grouting head needs to be stably connected with the prefabricated grouting slot hole. The traditional connection methods include artificial support to stabilize the grouting head, and thread The connection makes the grouting head stable, the artificial support method has poor stability, and the screw connection method is troublesome to operate

[0007] Fourth, during the construction of the prefabricated subway station, there are many on-site equipment and the environment is complex, and the grouting delivery pipe is very messy after being stretched, which makes it difficult for workers and other equipment to walk and move

[0008] Fifth, during the construction process, the grouting delivery pipe will be dragged along the ground, and there will be a lot of muddy water attached to it, which is inconvenient to clean up during storage
