Subsequently, multiple second support seats 3 are moved, which can move the pressure plate 100 installed on them, so that the waterstop 300 is pressed against the inner wall of the box culvert 200 along the circumference of the box culvert 200.

During the movement of the first support 2 and the second support 3, the support 1 can provide multiple points of leverage for the diver's work, enabling the diver to work underwater for extended periods of time and further reducing the difficulty of underwater operations.

The first connecting rod 42 is provided with a first connecting hole at one end inside the connecting tube 44, and the second connecting rod 43 is provided with a second connecting hole at one end inside the connecting tube 44. Multiple first fixing holes and multiple second fixing holes are arranged at intervals along the extension direction of the connecting tube 44. The first fixing holes and the second fixing holes are arranged symmetrically along the axis of the extension direction of the connecting tube 44. When the first connecting rod 42 slides to the designated position within the connecting pipe 44, the bolt's thread passes through the first fixing hole, the first connecting hole, and the second fixing hole in sequence. The bolt head abuts against the outer wall of the connecting pipe 44 around the first fixing hole, and the third nut abuts against the outer wall of the connecting pipe 44 around the second fixing hole and is tightened with the bolt to fix the sliding position of the first connecting rod 42 within the connecting pipe 44. When the second connecting rod 43 slides to the designated position within the connecting pipe 44, the bolt's thread passes through the first fixing hole, the second connecting hole, and the second fixing hole in sequence. The bolt head abuts against the outer wall of the connecting pipe 44 around the first fixing hole, and the third nut abuts against the outer wall of the connecting pipe 44 around the second fixing hole and is tightened with the bolt to fix the sliding position of the second connecting rod 43 within the connecting pipe 44, thereby completing the adjustment of the length of the support member 4. The designated sliding positions of the first connecting rod 42 and the second connecting rod 43 within the connecting pipe 44 refer to positions where the second connecting rod 43 can abut against or separate from the inner wall of the box culvert 200. This configuration allows for simultaneous adjustment of the lengths of the first connecting rod 42 and the second connecting rod 43 extending into the connecting tube 44, as well as individual adjustment of the lengths of the first connecting rod 42 and the second connecting rod 43 extending into the connecting tube 44, making the adjustment range of the support member 4 length more flexible and convenient.

[0075] In an optional embodiment, see [link to relevant documentation] Figure 3 The underwater work platform for the waterstop 300 also includes several first work platforms 51. The first work platforms 51 are fixedly installed on the support 1. Divers can stand or sit on the first work platforms 51 to carry out their work. That is, the first work platforms 51 provide a point of leverage for divers to work underwater.

[0076] For example, see Figure 1 and Figure 4 The first working platform 51 is along the width direction of the box culvert 200 ( Figure 4 A steel plate extending along the X direction is used to weld the first working platform 51 to the bracket 1.

[0077] In another alternative embodiment, see [link to relevant documentation]. Figure 1 and Figure 4 The underwater working platform for the waterstop 300 also includes several second working platforms 52, which are rotatably mounted on the support 1. Each second working platform 52 has a horizontal orientation (…). Figure 4Construction status extending in the X or Y direction and along the vertical direction ( Figure 4 The second working platform 52 extends into a retractable state (Z-direction). During construction, divers can stand or sit on the second working platform 52 to perform their work, providing a foothold for underwater operations. When the support 1 is installed into or removed from the box culvert 200, the second working platform 52 can be switched to a retractable state to prevent collisions between the second working platform 52 and the box culvert 200, thus ensuring the safety of the underwater working platform used for the waterstop 300 during movement.

[0078] In this embodiment, see Figure 3 and Figure 9 The underwater work platform for the waterstop 300 also includes a connecting rope 521. One end of the connecting rope 521 is connected to the second work platform 52, and the other end is connected to the support 1. In the construction state, the connecting rope 521 is taut to limit the second work platform 52 to the construction state, ensuring the safety of divers when working on the second work platform 52.

[0079] For example, the connecting rope 521 is made of steel chain, and the second working platform 52 is made of steel plate.

[0080] Furthermore, the support 1 is provided with a rotatable limiting member. In the retracted state, the limiting member rotates to the side of the second working platform 52 away from the support 1 and contacts the second working platform 52. At this time, the second working platform 52 is clamped between the limiting member and the support 1, that is, it is limited to the retracted state. When the limiting member is rotated to the point of separation from the second working platform 52, the second working platform 52 can rotate.

[0081] In this embodiment, see Figure 9 The second working platform 52 is provided with a rotating shaft 522, and the bracket 1 is provided with a connecting ear plate 16. The rotating shaft 522 passes through the connecting ear plate 16 and rotates with the connecting ear plate 16 to realize the rotational connection between the second working platform 52 and the bracket 1.

[0082] In another alternative embodiment, see [link to relevant documentation]. Figure 4 It is equipped with both a first working platform 51 and a second working platform 52 to provide multiple points of leverage for divers' operations, thereby improving the convenience of underwater operations for divers.

[0083] In this embodiment, see Figure 1 and Figure 4 There are two first working platforms 51, and the two first working platforms 51 extend along the box culvert 200. Figure 4The first working platforms 51 are symmetrically arranged along the Y direction in the X direction, and two first working platforms 51 are arranged on the upper half of the bracket 1, and the diver can adjust the first supporting seats 2 and the second supporting seats 3 on the top of the bracket 1 in a sitting position on the first working platforms 51. Figure 4 The second working platforms 52 are symmetrically arranged along the Y direction in the X direction, and four second working platforms 52 are arranged on the upper half of the bracket 1 and four second working platforms 52 are arranged on the lower half of the bracket 1, the diver can adjust the first supporting seats 2 and the second supporting seats 3 on the upper half of the bracket 1 in a standing position on the four second working platforms 52 on the upper half of the bracket 1, and the diver can adjust the first supporting seats 2 and the second supporting seats 3 on the lower half of the bracket 1 in a standing position on the four second working platforms 52 on the lower half of the bracket 1.

[0084] Optionally, referring to Figure 2 and Figure 3 , the underwater operation platform for the water stop belt 300 further comprises a plurality of suspending members 6 which are detachably arranged on the bracket 1 and used to adjust the buoyancy of the bracket 1. The buoyancy of the bracket 1 is related to the volume of water displaced by the bracket 1, and the arrangement of the suspending members 6 can increase the volume of water displaced by the bracket 1, thereby increasing the buoyancy of the bracket 1; when it is required to reduce the buoyancy of the bracket 1 under other working conditions, the suspending members 6 can be detached from the bracket 1, which is convenient and fast.

[0085] Illustratively, the suspending members 6 are steel floating boxes which are detachably connected to the bracket 1 by bolts. Compared with the hollow structure, the volume of water displaced by the box is larger, which is more convenient for adjusting the buoyancy of the bracket 1.

[0086] Further, the buoyancy of the bracket 1 can be adjusted by using suspending members 6 with different volumes, which increases the adjustable range of the buoyancy of the bracket 1.

[0087] Optionally, referring to Figure 4 and Figure 7 , the underwater operation platform for the water stop belt 300 further comprises a walking assembly 7 which is arranged at the bottom of the bracket 1 and configured to drive the bracket 1 to move, so as to facilitate the diver to move the underwater operation platform underwater.

[0088] In this embodiment, the walking assembly 7 comprises a plurality of universal wheels which are arranged at the bottom of the vertical columns 111 located at the four corners of the bracket 1, so as to move the bracket 1 in any direction.

[0089] Further, the walking assembly 7 further comprises a brake member, when the bracket 1 is moved to a suitable position, the universal wheels can be braked by the brake member, so that the bracket 1 remains at the current position; when the bracket 1 needs to be moved, the universal wheels can be restored to the rotatable state by releasing the brake member.

[0090] Optionally, the underwater operation platform for the waterstop 300 further comprises a lighting member arranged on the support 1 and configured to provide a light source. The lighting member can provide light for the underwater operation of the worker, improve the visibility of the underwater operation, and improve the convenience of the underwater operation of the worker,

[0103] After the pressing plate 100 is connected to the inner wall of the box culvert 200 through the bolt, the following steps are further included:

[0104] S5, the binding member is removed from the first supporting plate 21, and the first supporting rod 22 is screwed to separate the first supporting plate 21 from the water stop belt 300; at the same time, the second supporting rod 32 is screwed until the second supporting plate 31 is separated from the corresponding pressing plate 100 and the suction force of the suction member 33 on the corresponding pressing plate 100 disappears.
