Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be 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 present invention, not to limit the present invention.

[0018] Such as Figure 1-4 As shown, a kind of subsea tunnel segment force deformation and leakage test device provided by the present invention includes a box body 1, a tunnel pipe 2 is buried in the box body 1, and is filled with seawater, and the tunnel pipe 2 is a shield pipe The shield segment here is made according to the scaling. The inner side and the outer side of the tunnel tube 2 are respectively equipped with pressure sensors 21. The pressure sensor 21 monitors the change of the pressure applied on the outside of the tunnel tube 2 and the change affecting the inner wall of the tunnel tu...

Abstract

The invention discloses a subsea tunnel segment stress deformation and leakage test device which comprises a box body, a tunnel pipe is embedded in the box body, pressure sensors are arranged on the inner side and the outer side of the tunnel pipe respectively, a supporting frame is arranged in the box body, a moving block is slidably connected to the supporting frame, the bottom of the moving block is fixedly connected with a transverse plate, and the transverse plate is fixedly connected with the bottom of the tunnel pipe. The bottom of the transverse plate is symmetrically connected with two sliding blocks in a sliding mode, the bottom of each sliding block is fixedly connected with a vertical plate, the lower ends of the two vertical plates are jointly connected with an arc-shaped elastic plate in a hinged mode, the transverse plate is provided with a driving device, and the driving device is used for driving the two sliding blocks to synchronously and oppositely slide. The two sliding blocks slide relatively and extrude the elastic plate, so that the elastic plate is elastically arched, the applied pressure is gradually reduced from the middle to the two ends, meanwhile, the monitoring range is wider, and problems existing in connection of duct pieces at different positions can be easily found.

Description

technical field [0001] The invention relates to the technical field of tunnel segment inspection, in particular to a subsea tunnel segment stress deformation and leakage test device. Background technique [0002] A system and method for testing stress deformation and water stop failure of a submarine shield tunnel, including a counter force frame, inside the counter force frame is fixed a support tube with an open top, inside the support tube is used to place segments to be tested, and on the top of the support tube It is detachably connected with a ring-shaped pressure plate, a vertical loading piece is provided between the reaction frame and the pressure plate, a horizontal loading piece is installed on the support cylinder, the support cylinder is connected with the water supply mechanism, and a sealing strip is included for setting on the segment Between the bottom surface and the support cylinder, between the top surface of the segment and the pressure plate.
