Description

Technical Field

[0001] The utility model relates to the technical field of immersed tube tunnel grouting simulation test, in particular to an immersed tube tunnel grouting simulation test platform. Background Art

[0002] Immersed tube tunnel grouting refers to a technical means of enhancing the stability, sealing and waterproofing of a tunnel by injecting slurry during the construction process of an immersed tube tunnel. This technology is often used for the reinforcement of immersed tube tunnel joints, surrounding soil, and tunnel structures, as well as for the prevention and control of water seepage. Before the actual application of immersed tube tunnel grouting, it is necessary to simulate the situation of the immersed tube tunnel at the bottom of the water. Although existing technologies cannot fully simulate the situation of immersed tube tunnel grouting at the bottom of the water, the overall safety and practicality of the immersed tube tunnel after grouting can be greatly increased after the immersed tube tunnel grouting simulation. In most immersed tube tunnel grouting simulations, the simulation will be based on the actual situation, and the intensity of the simulation will be much higher than the actual situation. However, in the use of existing immersed tube tunnel grouting simulation test platforms, although the immersed tube tunnel grouting simulation test platform can simulate the vibration effect, due to the length of the pipeline and the volatility of crops in the water, the simulated effect has a certain deviation. Therefore, it is necessary to design a immersed tube tunnel grouting simulation test platform to reduce the deviation of the above data. Utility Model Content

[0020] Through the above embodiment, the reciprocating motion of the submerged pipe in water is simulated by the spring 5, and the gravity of the pipe 7 and the grouting inside the pipe 7 is mainly used, and the elastic potential energy of the spring 5 cooperates with each other to simulate the horizontal force on the submerged pipe in water. The irregular shape of the protruding pipe 8 rotates, and the protruding pipe 8 hits and pushes the pipe 7, thereby simulating the impact of the submerged pipe in water.

[0023] One end of the limiting rod 18 is rotatably connected to the connecting rod 19, and the outer surface of the limiting rod 18 is slidably connected to the inner wall of the convex tube 8;

[0024] A groove 9 is formed on one side of the platform body 1. A slide plate 10 is slidably connected to the inner wall of the groove 9. A bracket 11 is fixedly connected to one side of the slide plate 10. One side of the bracket 11 is fixedly connected to the inner wall of the groove 9 through a plurality of bolts and the slide plate 10.

[0025] One side of the bracket 11 is rotatably connected to a rotating tube 12, and one side of the rotating tube 12 is rotatably connected to a limiting tube 13. The inner wall of the limiting tube 13 is slidably connected to the outer surface of the limiting rod 18, and the inner wall of the rotating tube 12 is slidably connected to the outer surface of the connecting rod 19;

The resilience of the spring 5 can reduce the deviation of the data. The slide 10, bracket 11, rotating tube 12 and limit tube 13 are removed by disassembly, and the direction of the limit rod 18 can be changed through the movable effect of the movable frame 17, thereby facilitating the removal of the convex tube 8 and also facilitating the replacement of the convex tube 8.
