[0002] A tunnel is an engineering structure buried in the ground. It is a form of human utilization of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, and military tunnels. The structure of a tunnel consists of two parts: the main building and ancillary equipment. The main building consists of a tunnel body and a tunnel portal. The ancillary equipment includes a car shelter, fire-fighting facilities, emergency communications, and drainage facilities. Long tunnels also have special ventilation and lighting equipment.

[0003] For example, a tunnel crack repair device provided by the utility model patent with publication number CN217176638U includes a crawler, a bottom plate is fixedly connected to the top of the crawler crossbeam, a slurry box is fixedly connected to the top center of the bottom plate, a discharge pipe is fixedly connected to the right bottom end of the slurry box, the right end of the discharge pipe is fixedly connected to the input end of the grouting pump, and the output end of the grouting pump is fixedly connected to the delivery pipe. In the utility model, the electric telescopic rod drives the mounting plate to approach the tunnel wall, the blower blows air to the crack through the air outlet pipe and the air outlet nozzle, cleans the dust and debris at the crack, and prevents the dust and debris from affecting the repair quality. The slurry is sprayed from the grouting nozzle through the grouting pump, the discharge pipe, and the delivery pipe to repair the crack. The motor drives the rotating shaft to rotate, which is convenient to drive the mounting plate to rotate, thereby changing the direction of the grouting nozzle and the air outlet nozzle, and realizing the adjustment of the repair position. It is convenient and fast, saving time and effort, and is worthy of vigorous promotion.

[0004] During long-term use, tunnels are easily damaged by rainwater and other factors and leak. In order to ensure the normal use of tunnels, it is necessary to use repair devices to repair tunnels to prevent and control tunnel water damage. However, in the existing technology, most repair devices have fixed structures and single functions, making it difficult to repair leakage points at different angles and positions in the tunnel, thereby affecting the use effect of the repair devices.

[0050] In the above technical scheme, a repair device and method for preventing and controlling tunnel water damage provided by the present invention has the following beneficial effects: by setting a transmission mechanism, when in use, a proper amount of tunnel repair slurry is added to the storage barrel through the slurry adding port on the storage barrel, and then, after pushing the vehicle body to the tunnel position that needs to be repaired, the servo motor is started, so that the output shaft of the servo motor drives the screw rod to rotate, so that the U-shaped slide plate is threadedly connected to the screw rod, and the U-shaped slide plate slides upward in the fixed square tube, so that the repair spray plate and the trowel plate move upward until the repair spray plate and the trowel plate move to a suitable height, and then, the cylinder is started, so that the cylinder rotates with the bearing plate through the hinge seat A, and the cylinder piston end rotates with the rotating seat through the hinge seat B, so that the rotating seat rotates with the fixed seat through the rotating shaft, so that the repair spray plate and the trowel plate The trowel plate rotates, and when it contacts the inner wall of the tunnel, the trowel plate will squeeze the inner wall of the tunnel, so that the trowel plate drives the connecting plate and the movable block to slide in the movable groove, so that the spring is forced to shrink, so that the trowel plate can always contact the inner wall of the tunnel until the repair spray plate and the trowel plate rotate to a suitable angle. Subsequently, the booster pump is started to suck the repair slurry from the storage barrel through the slurry suction pipe, and spray it from the nozzle on the repair spray plate through the slurry outlet pipe. At the same time, the vehicle body is pushed to make the trowel plate slide on the inner wall of the tunnel, so that the trowel plate can smooth the tunnel repair slurry sprayed on the inner wall of the tunnel until the leakage points formed by tunnel water damage are repaired, so as to play a role in preventing and controlling tunnel water damage. Compared with the prior art, the design of the present invention is ingenious and reasonable, and different angles of the inner wall of the tunnel can be repaired, and the use effect is better.

[0051] The present invention sets a guide assembly, utilizes the sliding cooperation between the guide block and the guide groove, and sets the guide groove as an arc structure, so that when the rotating seat rotates with the fixed seat through the rotating shaft, the guide block will slide in the guide groove, causing the repair spray plate and the trowel plate to rotate, so that the guide block can limit the rotation angle of the repair spray plate and the trowel plate, avoiding that the rotation freedom of the repair spray plate and the trowel plate is too large, which affects the use effect of the present invention. The present invention is provided with a quick-release component. According to the tunnel angle position to be repaired, the trowel plate is moved, so that the trowel plate drives the connecting plate to move, so that the limit block squeezes the inner wall of the limit groove, so that the six connecting spring plates are deformed by force and tilted relatively until the limit block contacts the inner wall of the accommodating groove. At this time, the six connecting spring plates no longer tilt, until the limit block no longer contacts the inner wall of the accommodating groove. At this time, the trowel plate is disassembled, and the six connecting spring plates are no longer stressed and tilted away from each other to their original shapes. Then, a suitable trowel plate is selected to squeeze the arc surface of the limit block into the notch of the accommodating groove, so that the six connecting spring plates are deformed by force and tilted relatively until the limit block contacts the inner wall of the accommodating groove. At this time, the six connecting spring plates no longer tilt, until the limit block contacts the inner wall of the limit groove. At this time, the six connecting spring plates are no longer stressed and tilted away from each other until the limit block is engaged with the limit groove. At this time, the connecting spring plate returns to its original shape, and the side surface of the connecting plate contacts the side surface of the movable block.
