Description

Technical Field

[0001] The utility model relates to a grouting device, in particular to a one-way flow grouting and plugging device. Background Art

[0002] The existing grouting device does not have an automatic closing function, cannot automatically close the channel after the grouting stops, and cannot quickly block and transfer when changing holes. Therefore, a one-way flow grouting and blocking device is needed to improve the above problems. Summary of the invention

[0003] The utility model aims to provide a grouting and plugging device which can automatically close the connecting pipe and quickly plug the grout connecting pipe for one-way flow.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] The grouting and plugging device for one-way flow, the grouting device 6 is a hollow cylinder, the center holes of the upper and lower end faces are respectively connected with the coaxial connecting pipe 1 and the grouting pipe 8 whose inner diameter is smaller than the inner diameter of the grouting device, the center hole of the lower end face of the grouting device 6 is fixedly connected with the lower end outer side of the coaxial sleeve 5 through a plurality of radial connecting rods 7, the sleeve 5 is movably matched with the sliding rod 4, the piston plate 2 fixedly connected to the upper end of the sliding rod 4 is movably matched with the inner wall of the connecting pipe 1, the surface of the sliding rod 4 is surrounded by a spring 3, the upper end of the spring 3 is connected with the piston plate 2, the lower end of the spring 3 is connected with the upper end surface of the sleeve 5, the lower end of the grouting pipe 8 is docked with the coaxial and same-diameter hole at the center of the upper end face of the cube-shaped or rectangular slot 9, the coaxial and same-diameter hole at the center of the lower end face of the slot 9 is docked with the grouting pipe 11, the inner walls on the opposite sides of the slot 9 are movably matched with the plugging plate 10, the other opposite sides of the slot 9 are open, and the outer end of the plugging plate 10 extends out of the slot 9.

[0006] The beneficial effects of the utility model are:

[0007] The slurry enters through the connecting pipe 1 and squeezes the piston plate 2, so that the slide rod 4 squeezes the spring 3 and enters the sleeve 5. The slurry enters the middle of the grouting device 6 and is discharged through the grouting pipe 8. When grouting is no longer required, the piston plate is pushed back by the spring to automatically restore the position to close the connecting pipe. The grouting pipe 8 can be blocked by inserting the blocking plate into the slot, thereby reducing the waste of grouting material, being simple to operate and reusable.
