Description

Technical Field

[0001] The utility model relates to the technical field of underwater grouting construction, in particular to a sealing plate for underwater cement pouring. Background Art

[0002] When pouring concrete underwater, the vertical conduit underwater pouring method is often used. The method is to use a conduit to transport concrete to isolate it from water, rely on the deadweight of the concrete in the pipe, and press the concrete around the pipe mouth to flow and diffuse inside the already poured concrete to complete the concrete pouring work.

[0003] When installing a vertical conduit, it is necessary to hoist the conduit into the drill hole through a hoisting device. During the installation process, in order to prevent foreign matter from falling into the conduit and affecting the quality of later concrete molding, a sealing plate is required at the pipe mouth for sealing. The existing conduit sealing plate has a simple structure and is only buckled at the conduit mouth for sealing when used. It is very easy to fall off. In view of this, we propose a sealing plate for underwater cement pouring. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] This embodiment provides a technical solution:

[0028] See also Figure 1-Figure 6 A sealing plate for underwater cement injection comprises a grouting pipe 1, and a plurality of clamping holes 10 are provided on the inner wall of the top opening of the grouting pipe 1. A sealing part 2 is installed on the top of the grouting pipe 1, and the sealing part 2 comprises a sealing sealing plate 20, and a sealing slot 201 is provided on the bottom surface of the sealing sealing plate 20, and the top of the grouting pipe 1 is plugged into the sealing slot 201, and a plurality of mounting grooves 202 are provided on the top of the sealing sealing plate 20, and a guide rod 23 is fixed to the inner wall of the mounting groove 202, and a spring 24 is sleeved on the guide rod 23; a slider 21 is also slidably installed in the mounting groove 202, and a sliding hole slidably connected to the guide rod 23 is provided on the slider 21; a clamping head 22 is installed on one end face of the slider 21 away from the guide rod 23, and the end of the clamping head 22 is inserted into the sealing sealing plate 20 and clamped into the corresponding clamping hole 10.

[0029] In this embodiment, the cross-sectional shape of the sealing slot 201 is annular, and the size of the sealing slot 201 is adapted to the size of the grouting pipe 1 . This design is conducive to ensuring the sealing of the connection between the sealing slot 201 and the grouting pipe 1 .

[0030] In this embodiment, a blocking rod 25 is fixedly installed on the top of the slider 21, and the blocking rod 25 is cylindrical. The setting of the blocking rod 25 is convenient for pushing the slider 21 to move horizontally and for adjusting the horizontal positions of the slider 21 and the clamping head 22.

[0031] In this embodiment, a support bracket 11 is installed on the outer wall of the grouting pipe 1 near the top, and the support bracket 11 is fixedly connected to the grouting pipe 1 by bolts. The setting of the support bracket 11 supports and fixes the grouting pipe 1, thereby ensuring the stability of the grouting pipe 1.

[0032] In this embodiment, the size of the slider 21 is matched with the size of the mounting groove 202 . This design facilitates the slider 21 to slide horizontally in the mounting groove 202 , thereby ensuring the smooth movement of the slider 21 .

[0033] In the present embodiment, the overall shape of the sealing plate 20 is cylindrical, and the sealing plate 20 is made of stainless steel. The sealing plate 20 made of stainless steel has better structural strength, thereby ensuring the service life of the sealing plate 20.

[0034] In this embodiment, the slider 21 and the clamp 22 are an integrally formed structure, and the slider 21 and the clamp 22 are both made of stainless steel. The integrally formed slider 21 and the clamp 22 have better connection strength, ensure the structural strength of the slider 21 and the clamp 22, ensure the service life of the slider 21 and the clamp 22, and ensure the connection stability between the sealing plate 20 and the grouting pipe 1.

[0035] During specific use, the user first pushes the multiple baffles 25 toward the middle and the circumferential side, and the baffles 25 push the slider 21 to slide along the installation groove 202, and the slider 21 slides along the guide rod 23. The spring 24 is compressed by the slider 21 at the same time. At this time, the slider 21 drives the clamping head 22 to retract into the sealing slot 201, and then the user aligns the sealing slot 201 with the top of the grouting pipe 1 and inserts it. The top of the grouting pipe 1 is inserted into the sealing slot 201. Finally, the user releases the multiple baffles 25. Under the elastic action of the spring 24, the slider 21 is reset and drives the clamping head 22 to reset. The clamping head 22 is then clamped into the clamping hole 10, and the sealing sealing plate 20 is sealed at the top of the grouting pipe 1.
