Underwater intelligent docking monitoring test device and method for immersed tunnel

Abstract

The invention provides an underwater intelligent docking monitoring test device and method for an immersed tunnel. The device comprises a pipe joint moving end model, a pipe joint fixed end model, a test pool, a moving mechanism and a control end. The pipe joint fixed end model is installed in the test pool and located below the water surface, and the moving mechanism is installed above the test pool. The pipe joint moving end model is connected with the moving mechanism and can be driven by the moving mechanism to adjust the distance between the pipe joint moving end model and the pipe joint fixed end model in the horizontal direction and the vertical direction. The pipe joint moving end model is provided with a transmitting mechanism, the pipe joint fixed end model is provided with a measuring mechanism, and the control end is in signal connection with the transmitting mechanism, the measuring mechanism and the moving mechanism. Real-time attitude information in the butt joint process of the pipe joints is simulated and monitored through a long-distance underwater sound guiding system and a short-distance displacement monitoring system, and high-precision and multi-scale whole-process real-time monitoring simulation of sinking and butt joint of the immersed pipe joints is achieved.

Description

technical field [0001] The invention relates to the technical field of immersed tube tunnel construction, in particular to an underwater intelligent docking monitoring test device for immersed tube tunnels and a method thereof. Background technique [0002] In large-scale underwater tunnel projects, the immersed tube method has been more and more widely used in China due to the advantages of the shortest construction period, the shortest tunnel extension, less geological constraints, and almost no geological constraints. The sinking and docking of pipe joints is one of the key processes in the construction of immersed tunnels. [0003] At present, the main measurement methods used in the pipe joint sinking and docking process include: high-precision optical measurement method, measurement tower positioning method, underwater sonar measurement and positioning method, underwater pull-line positioning method, etc. In the monitoring process, there are generally problems such as...

[0004] The patent document CN108385728A discloses a push-type final joint of an immersed tube tunnel and its butt joint construction method. The push-type final joint includes a connecting socket arranged on the pipe section to be installed, and a jacking pipe joint is sleeved in the connecting socket; Including the push piece, a cavity that can accommodate the push piece is provided in the connecting socket, and a grouting pipe is pre-buried in the cavity; it further includes a water stop component, which includes three water stop belts, the first stop The water belt is set on the end face of the pushed-out end of the jacking pipe joint, and the second water stop and the third water stop are set on the outer periphery of the jacking pipe joint; the second water stop can be pushed out with the jacking pipe joint. One end of the second waterstop is fixedly connected to the jacking pipe joint, the other end is fixedly connected to the connecting socket, and the third waterstop is sleeved between the jacking pipe joint and the connecting socket, but the The structure of the docking is special, and it is not universally applicable to the underwater intelligent docking of the immersed tube tunnel
