Description
Technical Field
[0001] This utility model relates to the technical field of equipment for tunnel construction, specifically a water-blocking grouting device for tunnel engineering. Background Technology
[0002] In tunnel construction, water-blocking grouting is an essential step. Grouting water-blocking is a construction method in which grout prepared with grouting materials in a certain proportion is injected into the voids behind the tunnel surrounding rock or lining wall in a certain way. After solidification and hardening, it serves to block water and reinforce the surrounding rock.
[0003] Existing water-blocking grouting mechanisms typically involve mounting a tank on a trolley, filling the tank with grout, and then using a grouting pump to spray the grout from the tank through nozzles into the gaps behind the tunnel surrounding rock or lining wall to complete the grouting operation.
[0004] However, the grout in the tank is prone to uneven distribution, resulting in different grout concentrations and even sedimentation, which in turn affects the grouting effect. Utility Model Content
[0005] The purpose of this invention is to provide a water-blocking grouting device for tunnel engineering, in order to solve the problem that the grout in the tank is easily unevenly distributed, resulting in different grout concentrations and even sedimentation, which affects the grouting effect.

Rollers are installed at the bottom of the base, and vertical plates are fixedly installed at the left and right ends of the top of the base. The tank is rotatably connected between the two vertical plates. Support pipes are fixedly connected to the left and right sides of the tank, and the support pipes are rotatably connected to the vertical plates. A water pipe is connected to one side of the support pipe, and the water pipe is connected to a grouting nozzle mechanism. The water pipe and the support pipe are rotatably connected. An inlet is provided on the tank near the grouting nozzle mechanism, and a cover plate is installed at the inlet. A push plate is slidably connected inside the tank, and a spring is fixedly installed between the push plate surface away from the inlet and the inner wall of the tank. A driving mechanism is provided on the base, and the driving mechanism controls the rotation of the tank.
[0007] As a preferred technical solution of this utility model: the driving mechanism includes a motor, the motor is fixedly mounted on the base, a gear is coaxially connected to the output shaft of the motor, a gear ring is sleeved on the outer side of the tank, and the gear and the gear ring mesh with each other.
[0008] As a preferred technical solution of this utility model: an air pipe is rotatably connected to another of the support pipes, and an air pump is fixedly installed on the vertical plate, with the air pump connected to the air pipe.

[0010] As a preferred technical solution of this utility model: a push rod is fixedly installed on the base near the air pump.
[0011] The beneficial effects of this utility model using the above technical solution are as follows: This utility model has a simple structure and ingenious design. By loading the slurry into the tank, the pusher plate moves backward as the slurry is poured in, compressing the spring. The grouting nozzle mechanism sprays the slurry from the tank into the gaps.

[0017] Please see Figure 1-3 One embodiment of this utility model is a water-blocking grouting device for tunnel engineering, which includes a base 1 and a tank 4. Rollers 2 are installed at the bottom of the base 1, and vertical plates 3 are fixedly installed at the left and right ends of the top of the base 1, respectively. The tank 4 is rotatably connected between the two vertical plates 3.
[0018] Support pipes 5 are fixedly connected to the left and right sides of the tank body 4. The support pipes 5 are rotatably connected to the vertical plate 3. A water pipe is connected to one of the support pipes 5. The water pipe is connected to the grouting nozzle mechanism 6. The water pipe and the support pipe 5 are rotatably connected. The water pipe and the support pipe 5 are connected by bearings.
[0019] A feed inlet 7 is provided on the tank body 4 near the grouting nozzle mechanism 6. A cover plate is installed at the feed inlet 7, and the grout is loaded into the tank body 4 through the feed inlet 7. A push plate 8 is slidably connected inside the tank body 4, and a spring 9 is fixedly installed between the plate surface of the push plate 8 away from the feed inlet 7 and the inner wall of the tank body 4.
[0020] A drive mechanism is provided on the base 1, which controls the rotation of the tank 4. The drive mechanism includes a motor 10, which is fixedly mounted on the base 1. A gear 11 is coaxially connected to the output shaft of the motor 10. A gear ring 12 is fitted onto the outer side of the tank 4, and the gear 11 and the gear ring 12 mesh with each other. The motor 10 drives the gear 11 to rotate, and the gear 11 meshes with the gear ring 12, ultimately driving the tank 4 to rotate, so that the slurry inside the tank 4 remains in a uniform state.
[0021] An air pipe 13 is rotatably connected to another support pipe 5, and an air pump 14 is fixedly installed on the vertical plate 3. The air pump 14 is connected to the air pipe 13, and the air pipe 13 is also connected to the support pipe 5 through a bearing. By inflating the tank 4 with air by the air pump 14, the push plate 8 can push the slurry to move more smoothly, ensuring that there is always slurry at the grouting nozzle. During the movement of the push plate 8, the slurry on the inner wall of the tank 4 can also be cleaned.
[0022] A push rod 15 is fixedly installed on the base 1 near the air pump 14. The movement of the entire device can be controlled by the push rod 15, which is convenient and quick.
[0023] Specific implementation method: By loading slurry into the tank 4, the push plate 8 moves backward as the slurry is poured in, the spring 9 is compressed, and the grouting nozzle mechanism 6 sprays the slurry in the tank 4 into the gap. The spring 9 gradually returns to its original state, driving the push plate 8 to move, so that the slurry in the tank 4 is always concentrated near the grouting nozzle mechanism 6. The air pump 14 inflates the tank 4, which ensures that the movement of the push plate 8 is more stable.
[0024] The motor 10 drives the gear 11 to rotate, and the gear 11 meshes with the gear ring 12 to drive the tank 4 to rotate, so that the slurry in the tank 4 is always kept in a uniform state.
