[0041] Embodiment 1

[0042] In order to solve the problem that when the existing waterproof grouting device grouts the cracks or joints of the side structure or the top structure, it is impossible to recover the falling slurry, which is likely to cause the falling slurry to pollute the side wall, the ground, the construction personnel or the equipment, etc., resulting in difficult cleaning. As Figures 1-6 shown, a waterproof grouting device includes a moving mechanism (including pulleys, a driving mechanism for driving the pulleys to move or a handle for pushing the pulleys to move, and a mounting platform provided on the pulleys), a grouting mechanism provided on the moving mechanism, the grouting mechanism includes a grouting pump, a slurry bucket cooperating with the grouting pump, and a grouting pipe 1 with a nozzle connected to the grouting pump. A longitudinal telescopic mechanism 2 (provided on the mounting platform) is provided on the moving mechanism, and a slurry recovery chamber 3 with an open top is provided on the longitudinal telescopic mechanism 2 (which can be a hydraulic telescopic mechanism) (its size and depth are set according to requirements). The grouting pipe 1 is movably and fixedly cooperated with the longitudinal telescopic mechanism 2 and movably and hermetically cooperated with the slurry recovery chamber 3, and the nozzle of the grouting pipe 1 is higher than the top opening of the slurry recovery chamber 3.

[0043] In practice, when cracks or joints appear at the top of the floor slab, the grouting mechanism, the longitudinal telescopic mechanism, and the slurry recovery chamber 3 will be moved to the cracks or joints through the moving mechanism. The longitudinal telescopic mechanism is adjusted to rise so that the nozzle end of the grouting pipe 1 is placed in the cracks or joints. Since the grouting pipe 1 is movably fixed in cooperation with the longitudinal telescopic mechanism 2 and movably sealed in cooperation with the slurry recovery chamber 3, the depth of the nozzle extending into the cracks or joints can be adjusted. The slurry recovery chamber 3 can be separated from or in contact with the floor slab (when it is for the side wall, it needs to be in contact, at least on the low-end side). The grouting pump is turned on, and at the same time, the moving mechanism is driven or pushed to move the grouting pipe 1 along the cracks or joints. The slurry ejected from the nozzle of the grouting pipe 1 can fill the cracks or joints. When the slurry falls back, it can fall into the slurry recovery chamber 3. In this embodiment, a longitudinal telescopic mechanism is provided on the moving mechanism, and a slurry recovery chamber is provided on the longitudinal telescopic mechanism. The grouting pipe is movably fixed in cooperation with the longitudinal telescopic mechanism and movably sealed in cooperation with the slurry recovery chamber. The purpose is to facilitate adjusting the length of the nozzle extending out of the slurry recovery chamber according to the depth of the cracks or joints. At the same time, when grouting the cracks or joints of the side structure or the top structure, it is convenient to recover the falling-back slurry (such as too thin slurry or slurry with too slow setting speed) in case of leakage, thus avoiding the problem of the falling-back slurry polluting the side wall, the bottom wall or the equipment, and at the same time avoiding the problem of difficult cleaning.

[0044] Embodiment 2

[0045] On the basis of Embodiment 1, a pipe hole 4 is provided on one side of the bottom of the slurry recovery chamber 3. The grouting pipe 1 passes through the pipe hole 4, and the grouting pipe 1 is connected to the pipe hole 4 through a rubber seal 5. Since the rubber seal 5 is elastic, the depth of the nozzle extending into the crack or joint will be adjusted by pushing the opening side of the slurry recovery chamber 3 or pulling it in the opposite direction, and the adjusted grouting pipe 1 is fixed on the longitudinal telescopic mechanism.

[0046] Embodiment 3

[0047] On the basis of Embodiment 2, on the other side of the side where the pipe hole 4 is provided, a recovery hole 6 is further provided at the bottom of the slurry recovery chamber 3. A threaded connector 7 is provided on the recovery hole 6, and a threaded pipe 8 is threadedly connected to the threaded connector 7. The provision of the recovery hole and the threaded connector on the slurry recovery chamber facilitates the discharge of the recovered slurry through the connection of the threaded connector and the threaded pipe, so as to avoid the problem of being quickly filled up, and at the same time it is also convenient for disassembly and blockage removal.

[0048] Embodiment 4

[0049] On the basis of Embodiment 3, a connector 9 is provided on the longitudinal telescopic mechanism 2, and a fixing member 10 for adjusting and fixing the position of the grouting pipe 1 is provided on the connector 9.

[0050] The fixing member 10 is a T-shaped groove with an open top and a closed bottom. A sliding groove 11 is correspondingly arranged on the opposite sides inside the T-shaped groove. In practice, it is not excluded that the fixing member can also be of other structures.

[0051] A T-shaped block 12 matching the T-shaped groove is arranged on the grouting pipe 1 at one end of the nozzle. A threaded rod 13 that slidably matches the sliding groove 11 is arranged on the T-shaped block 12. A nut that matches the threaded rod is arranged on the threaded rod to fix the grouting pipe on the fixing member.

[0052] A longitudinal connecting head 14 with a hole or a transverse connecting head is arranged on the longitudinal telescopic mechanism 2.

[0053] A connecting head 15 with a hole matching the longitudinal connecting head 14 with a hole or the transverse connecting head is arranged at the bottom of the slurry recovery chamber 3 and is fixed by bolts and nuts.

[0054] The connecting member 9 includes a clamping member A16, a clamping member B17, a connecting rod 18 connecting the clamping member A16 and the clamping member B17, and bolts and nuts for fixing the clamping member A16 and the clamping member B17. The connecting member can also be only the connecting rod arranged on the longitudinal telescopic mechanism.

[0055] When the connecting member is movably connected to the longitudinal telescopic mechanism, by adjusting the clamping height of the clamping member A16 and the clamping member B17 (the clamping member A16 and the clamping member B17 are elastic to facilitate the opening or closing of the opposite sides of the connecting rod 18) on the longitudinal telescopic mechanism, after adjustment, it is fixed by bolts and nuts. After fixing, the T-shaped block 12 slides and moves in the sliding groove 11 (on the same side as the grouting pipe 1, which is also convenient for adjustment). During the movement, the rubber seal 5 is pulled. When it moves to an appropriate position, the grouting pipe is fixed on the fixing member by the cooperation of the threaded rod and the nut.

[0056] When grouting the cracks or joints of the side structure or the top surface structure, it is convenient to adjust the length of the nozzle protruding from the slurry recovery chamber through the fixing member or the cooperation of the fixing member and the connecting member. When switching between grouting the cracks or joints of the side structure and the top surface structure, the slurry recovery chamber and the like arranged on different longitudinal telescopic mechanisms are used to achieve grouting and slurry recovery. That is, two longitudinal telescopic mechanisms can be arranged on the installation platform, and slurry recovery chambers 3 for grouting the cracks or joints of the side structure and the top surface structure are respectively arranged on each longitudinal telescopic mechanism.

[0057] Embodiment 5

[0058] Based on Embodiment 4, one side of the top of the slurry recovery chamber 3 is inclined, with the end where the recovery hole 6 is located being the high end and the end where the pipe hole 4 is located being the low end, which is convenient for grouting on an arc surface or an inclined surface, and at the same time is conducive to scraping the excess slurry into the slurry recovery chamber. That is, when moving, the high end is located at the rear end of the traveling direction. The inclination angle of one side of the top of the slurry recovery chamber 3 is 5° - 50°, such as 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15° or 20°, etc., which is convenient for selection and setting according to the practical application scenario, and at the same time ensures the liquid collection height of the slurry recovery chamber.
