When the inner wall of the tunnel is grouted by the device, During waterproofing construction, the robotic arm 2 is approached to the construction site to drive the storage cart 1 to spray the waterproof slurry, and then the bonding component 601 is extended by the pushing component 5. The robotic arm 2 drives the bonding component 601 to move and evenly smooth the sprayed slurry. The stabilizing component 602 makes the bonding component 601 more stable when moving. At this time, it is more convenient to carry out waterproofing construction of gaps on the ground. The robotic arm 2 can push the nozzle 4 close to the spraying position and move the bonding component 601 to apply. The storage cart 1 includes a slurry storage part and an output pump. For the staff in this technical field, the storage cart 1 and the robotic arm 2 are both prior art and will not be elaborated on here.

[0023] like Figure 2 and Figure 4As shown, the pushing component 5 includes a connecting seat 508 fixedly connected to the surface of the nozzle 4, the upper end of the connecting seat 508 is fixedly connected to a driving motor 501, the output end of the driving motor 501 is fixedly connected to a lead screw 502, the surface of the lead screw 502 is threadedly connected to a nut 503, and the side end of the nut 503 is fixedly connected to a push rod 504. When it is necessary to extend or retract the bonding component 601, the driving motor 501 can be started, and the driving motor 501 drives the lead screw 502 to rotate, and the lead screw 502 drives the nut 503 and the push rod 504 to move through the surface thread until the end of the thread, and then the driving motor 501 is turned off to push the bonding component 601 to extend or retract. The driving motor 501 is a three-phase asynchronous motor. For the staff in this technical field, the driving motor 50 1 is the prior art and will not be described in detail herein. The upper end of the connecting seat 508 is fixedly connected with a rotating seat 505, and the rotating seat 505 is rotatably connected to the surface of the screw 502.

The two stabilizing plates 6022 at the side ends of the "C"-shaped plate 6013 are both slidably connected to the inner wall of the bottom plate 6011. When the "C"-shaped plate 6013 and the scraper 6014 are attached to the inner wall of the tunnel for construction, they are prone to tilting and shaking.

The side ends of the two stabilizing plates 6022 are fixedly connected with blocking blocks 6021. The spring 6012 is sleeved on the circumferential surface of the nozzle 4. When the stabilizing plates 6022 limit the attachment component 601, the stabilizing plates 6022 are easily pulled off and damaged. The blocking blocks 6021 are used to limit the pulling of the stabilizing plates 6022, so that the blocking blocks 6021 are not prone to detachment when pulled.
