Description

Technical Field

[0001] The utility model relates to the technical field of shield segment repair, in particular to a tunnel construction segment rupture repair device. Background Art

[0002] At present, the pipe segment is the main assembly component of shield construction and the innermost barrier of the tunnel. It is responsible for resisting soil pressure, groundwater pressure and some special loads. Figure 4 As shown, the existing production of pipe segments usually adopts high-strength impermeable concrete to ensure reliable bearing and waterproof performance. The production mainly uses the finished pipe segment mold after sealing and pouring concrete. Before use, the pipe segment needs to be checked whether the pipe segment has defects and needs to be repaired. During the repair, a repair device is needed for auxiliary repair. CN201922259931.4 discloses a special repair platform for pipe segments, including a ground, a platform body set on the ground, and a pipe segment body set on the platform body. The top of the platform body is provided with an arc-shaped support plate for supporting the pipe segment body. The outer arc surface of the support plate is consistent with the inner arc surface of the pipe segment body and fits. The special repair platform for pipe segments is positioned by fitting the arc surface with the pipe segment, but the pipe segment is not locked and fixed during use, which may cause the pipe segment to deviate during the repair process. In addition, the special repair platform for pipe segments is only suitable for repairing the outer arc surface of the pipe segment, and is not very suitable for repairing the inner arc surface.

[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0015] like Figure 4 As shown, a grouting hole 41 is provided at the center of a shield segment 4 in the prior art, and positioning holes 42 are provided on both sides of the segment 4 .

[0016] like Figure 1-3 As shown, the present embodiment provides a tunnel construction segment rupture repair device, comprising a bracket, on which a rotating block 13 is rotatably connected, the bracket comprising a base plate 11, on the upper side of which two vertical plates 1 are fixedly connected, a rotating shaft 12 is rotatably connected between the two vertical plates 1, the rotating block 13 is fixed on the rotating shaft 12, and one side of the vertical plate 1 is provided with a power device for driving the rotating shaft 12 to rotate, the power device is not shown in the figure, and the power device is a prior art, which will not be described in detail here.

[0017] Two supporting plates 2 are fixedly connected to the rotating block 13, one of which is provided with a convex surface protruding upward on one side of the supporting plate 2, which matches and combines with the inner arc surface of the pipe segment 4, and the other supporting plate 2 is provided with a concave surface sunken downward on one side, which matches and combines with the outer arc surface of the pipe segment 4. Each supporting plate 2 is provided with a positioning device 3 and a locking device.

[0018] During the working process, the outer arc surface or the inner arc surface of the pipe segment 4 can be repaired to adjust which support plate 2 is set upward, so that after the pipe segment 4 is placed on the support plate 2, the pipe segment can be positioned and locked by the positioning device 3 and the locking device before repair. The problem that the repair platform in the prior art cannot limit the position of the pipe segment and cannot repair the inner arc surface of the pipe segment is solved.

[0019] The following configuration is further made: the positioning device 3 includes a mounting plate 30, the upper side of the mounting plate 30 is fixedly connected to a column 31, one side of the column 31 is provided with a threaded hole, a screw 32 is threadedly connected to the threaded hole, and one end of the screw is fixedly connected to a positioning pin 33. During operation, after the segment 4 is placed on the supporting plate 2, the screw 32 is screwed, and the positioning pin 33 moves forward and is inserted into the positioning hole 42 of the segment 4, so that the segment 4 can be freed of the four degrees of freedom in the directions, thereby positioning the segment 4 and preventing the segment 4 from shifting during the repair process.

[0020] In addition, the locking device includes a stud 21, which is fixed to one side of the support plate 2, and a locking nut 23 is provided on the stud 21. The stud 21 passes through the grouting hole 41 of the pipe segment 4, and the pipe segment 4 can be pressed and fixed by screwing the locking nut 23. With the cooperation of the positioning device 3, the freedom of the pipe segment 4 in six directions is limited, so the pipe segment 4 can be completely limited. A pad 22 is sleeved on the stud 21, and the pad 22 is arranged between the locking nut 23 and the pipe segment 4. The pad 22 can further press the pipe segment 4, and at the same time, it is prevented that the pipe segment 4 is directly in contact with the locking nut 23, which may cause secondary damage to the pipe segment.

[0021] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
