In order to ensure the safe and efficient construction of the pipeline, people usually use construction methods such as overhead pipes, immersed pipes, jacking pipes, and cofferdam excavation, among which the most commonly used is immersed pipe construction.
[0003] The construction method of immersed pipe is to assemble the whole pipe on the river bank in advance, then use the horizontal pipe method to move the whole pipe horizontally across the entire river surface, and finally sink it by injecting water into the pipe. This type of construction method is simple to construct and easy to operate, and the whole pipe can be crossed across the river at one time. However, when there are obstacles in the middle of the river, or when it is inconvenient to assemble pipes on the river bank, it is necessary to carry out pipe docking and welding construction on the water surface. Usually people will set up a simple floating platform for water surface construction. However, it is not easy to perform positioning control when docking pipes on the simple floating platform, and the pipe welding is prone to deviation, which affects the construction.

An arc groove 11 for placing the immersed tube is provided on the support box 1, and an ear plate 12 is provided on the side wall of the support box 1 for fixed connection with an adjacent support box 1. A through hole is provided on the ear plate 12, and a bolt is inserted into the through hole. When the bolt is inserted into the through hole, an adjusting nut is sleeved on the bolt. When in use, two support boxes 1 are required to be used together. A section of the immersed tube to be welded is placed on each support box 1. The immersed tube is placed in the arc groove 11. The support box 1 floats on the water surface. The bolts pass through the holes on the ear plate 12, and the adjusting nuts are put on the ends of the bolts. The two support boxes 1 can be moved closer to each other by turning the adjusting nuts until the immersed tubes on the two support boxes 1 abut against each other. Since the two support boxes 1 are locked by the bolts and the adjusting nuts, the two sections of the immersed tube can move at the same time even if the water surface is not stable enough, so that the relative stability between the two sections of the immersed tube can be maintained. The staff can weld the immersed tubes while standing in the construction area, and the interface of the immersed tubes is not easy to shift during welding, and the welding is more accurate.
[0037] Reference Figure 1 A support edge 13 extends outward from the support box 1. The support edge 13 is perpendicular to the side wall of the support box 1 and is arranged along the outer edge of the arc groove 11 to support the immersed tube. The outer wall of the immersed tube contacts the support edge 13. When in use, a pair of support boxes are moved forward and the support edges 13 abut against each other. At this time, the welding parts of the two sections of the immersed tube are butted against each other. The workers can complete the welding work while standing in the construction area, which makes welding more convenient.
[0038] Reference Figure 2 and Figure 3 A plurality of receiving holes can be provided on the retaining edge, and the receiving holes are evenly distributed along the length direction of the retaining edge. A steel ball 14 is placed in each receiving hole. When the immersed tube is placed in the arc groove 11, the outer wall of the immersed tube abuts against the steel ball 14, so that the immersed tube can be rotated. During welding, the immersed tube can be rotated to expose the part to be welded blocked by the arc groove 11, which makes welding more convenient.
[0039] Reference Figure 2 and Figure 3 When rotating the immersed tube, the immersed tube can be directly pushed, or the rotating assembly 2 can be fixed on the supporting box 1 to drive the immersed tube to rotate, so that the immersed tube can be rotated more conveniently and labor-savingly. The rotating assembly 2 includes a driving part 21 and an abutting part 22. The abutting part 22 is rotatably connected to the inner wall of the supporting box 1. When the immersed tube is placed in the arc groove 11, the abutting part 22 abuts on the outer wall of the immersed tube. The driving part 21 is arranged on the inner wall of the supporting box 1 to drive the abutting part 22 to rotate. When the abutting part 22 rotates, the immersed tube is driven to rotate in the arc groove 11. The abutting part 22 includes an abutting roller 221 and a rotating frame 222. The rotating frame 222 is arranged on the inner wall of the supporting box 1. A rotating shaft is rotatably connected to the rotating frame 222. The abutting roller 221 is sleeved on the rotating shaft. The driving part 21 drives the rotating shaft to rotate. The driving part 21 includes a driving sprocket 211, a driven sprocket 212 and a chain 213. The driving sprocket 211 is rotatably connected to the inner wall of the supporting box 1, and a handle wheel 214 is coaxially fixed on the driving sprocket 211. The driven sprocket 212 is arranged on the abutting part 22 to drive the abutting part 22 to rotate, and the driven sprocket 212 and the driving sprocket 211 are transmitted through the chain 213. When the immersed tube is placed in the arc groove 11, the outer wall of the immersed tube abuts on the abutting roller 221, and the abutting roller 221 rotates under the drive of the driving sprocket 211 and the driven sprocket 212. When rotating, the immersed tube always abuts against the abutting roller 221, thereby driving the immersed tube to rotate, and the part to be welded can be rotated to be exposed, which is convenient for the staff to weld. The outer edge of the abutting roller 221 is provided with a plurality of anti-skid ribs 223, and the plurality of anti-skid ribs 223 are parallel to each other and evenly distributed on the outer edge of the abutting roller 221. The convex ridges are used to increase the friction force to prevent the immersed tube and the abutting roller 221 from slipping.
[0040] Reference Figure 2 and Figure 3The rotating frame 222 can be fixedly connected to the supporting box 1, or it can be slidably arranged on the inner wall of the supporting box 1, a slide groove is provided on the inner wall of the supporting box 1, the rotating frame 222 is inserted into the slide groove and slides in the slide groove, a spring 224 is sleeved on the rotating frame 222, one end of the spring 224 abuts against the bottom of the slide groove, and the other end of the spring 224 abuts against the rotating frame 222, and when the immersed tube is placed on the arc groove 11, the rotating frame 222 is pushed to slide to contact the bottom of the slide groove. The spring 224 can give a rebound force so that the abutting roller 221 can abut against the outer wall of the immersed tube more closely, reducing the possibility of slipping.
[0041] A section of the submerged tube to be welded is placed on each of the support boxes 1 in the present application. Two support boxes 1 are used together, and the submerged tube is placed in the arc groove 11. The support box 1 floats on the water surface. The bolts pass through the holes on the ear plate 12, and the adjusting nuts are put on the ends of the bolts. The two support boxes 1 can be brought closer to each other by turning the adjusting nuts until the submerged tubes on the two support boxes 1 abut against each other. Since the two support boxes 1 are locked by the cooperation of the bolts and the adjusting nuts, the two sections of the submerged tube can move at the same time even if the water surface is not stable enough, so that the relative stability between the two sections of the submerged tube can be maintained. The staff can weld the submerged tube while standing in the construction area, and the interface of the submerged tube is not easy to shift during welding, and the welding is more accurate.
