Technical Field

[0001] The invention relates to the technical field of tunnel construction, in particular to a grouting device used for plugging leakage of a tunnel water-stopping curtain. Background Art

[0002] The waterstop curtain is a continuous waterstop body used to prevent or reduce the flow of groundwater from the side walls and bottom of the foundation pit into the foundation pit. The waterstop wall formed by continuous mixing piles (cement-soil mixing piles, etc.), single-tube and three-tube rotary jet piles is called a waterstop curtain. Waterstop curtain is a concept, which is the general term for the peripheral waterstop series of the main body of the project. Cement-soil waterstop curtains are often used to intercept water in the foundation pit retaining system. If the bottom of the foundation pit is below the groundwater level and precipitation is difficult, it is basically necessary to set up a waterstop curtain to prevent groundwater leakage.

[0003] The existing solution is generally to first drill holes around the ground that needs to be waterproofed, and then use a cement pump truck to pump cement into the holes through a conduit.

Three evenly arranged connecting shafts 71 are fixedly arranged on the outer circumferential surface of the rotating shaft 7, and a scraper 72 is fixedly arranged on each connecting shaft 71. The scraper 72 fits the inner wall of the grouting pipe 4. By setting the limiting frame 45 in the grouting pipe 4, when the grouting pipe 4 is in operation, the slurry flowing in the grouting pipe 4 can drive the scraper 72 to rotate, and the rotating scraper 72 cleans the slurry attached to the inner wall of the grouting pipe 4.

When it moves into the straight groove 61, the elastic force of the spring 54 can push the knocking column 52 to knock the grouting pipe 4, so that the slurry inside the grouting pipe 4 vibrates, thereby improving the circulation efficiency of the slurry. When pouring cement, due to the viscosity and adhesion of the cement itself, gaps and pores are easily formed, and these gaps and pores will greatly affect the density and durability of the cement after solidification, and the vibration effect is to remove air and moisture from the cement mixture by vibrating the surface, thereby improving the density of the cement.

[0030] Reference Figure 6-Figure 8 The scraper 72 is arranged in a spiral shape. By arranging the scraper 72 in a spiral shape, the slurry can be pushed to one end when the scraper 72 rotates.

[0031] The specific scheme is as follows: when using the device, the staff first moves the device to a suitable position, and realizes the support function of the entire device by setting the support column 11 on the bottom plate 1, and sets a semicircular baffle 42 to protect the grouting pipe 4 during the grouting process, and ensures that good lighting conditions are provided during construction in the tunnel by setting the LED light 421 on the outer wall of the baffle 42, and starts the device to drive the motor 21 to drive the slurry to be transported to the grouting pipe 4, and during the grouting process, the slurry flowing in the grouting pipe 4 can drive the scraper 72 to rotate, and the rotating scraper 72 cleans the slurry attached to the inner wall of the grouting pipe 4, and the adapter 451 set in the grouting pipe 4 ensures that the adapter 451 can drive the grouting pipe 4 when the rotating shaft 7 rotates. The long rod 43 rotates, and the long rod 43 can drive the stirring rod 431 to rotate, ensuring that the slurry at the bottom of the floating plate 41 can be mixed evenly and maintain a horizontal state. When the limit column 531 moves on the arc groove 62, the spring 54 is in a compressed state. When it moves into the straight groove 61, the elastic force of the spring 54 can push the knocking column 52 to knock the grouting pipe 4, thereby causing the slurry inside the grouting pipe 4 to vibrate, thereby improving the circulation efficiency of the slurry. When pouring cement, due to the viscosity and adhesion of the cement itself, gaps and pores are easily formed, and these gaps and pores will greatly affect the density and durability of the cement after solidification, and the vibration effect is to remove air and moisture from the cement mixture by vibrating the surface, thereby improving the density of the cement.
