For this reason, the application proposes a model simulation test device for the tunnel to pass through the existing tunnel. The model simulation test device for the tunnel to pass through the existing tunnel is provided with a positioning cover at the originating hole and the receiving hole, and the hole that passes through the middle of the positioning cover The positioning hole makes the steel wire rope at the center of the starting hole and the receiving hole. During the soft soil vibration process, the steel wire rope is in a tensioned state, which effectively improves the deflection of the steel wire rope during soft soil vibration, thereby reducing the second tunnel model. Cannot pass through the receiving hole, resulting in test failure and need to re-test

The embodiment of the present application provides a model simulation test device for a tunnel passing under an existing tunnel, which relates to the technical field of simulation tests. The model simulation test device for the tunnel passing through the existing tunnel includes a simulation test component, a positioning component and a traction component. Fix the positioning cover and connecting plate to the connecting holes at the originating hole and the receiving hole, press the connecting plate tightly around the periphery of the originating hole and the receiving hole, pass the wire rope through the positioning cover at the originating hole and the receiving hole in sequence In the positioning hole, tie the steel wire rope to the fixed bracket on the positioning cover, then add soft soil into the simulation test body and vibrate, and make the steel wire rope in the center of the starting hole and the receiving hole through the positioning hole in the middle of the positioning cover. The steel wire rope is in a tensioned state, which effectively improves the vibration of the rock and soil. When the steel wire rope is offset, it reduces the situation that the second tunnel model cannot pass through the receiving hole, resulting in test failure and the need to re-test.
Description
technical field [0001] The present application relates to the technical field of simulation tests, in particular, to a model simulation test device for a tunnel passing through an existing tunnel. Background technique [0002] In the related technology, the tunnel passes through the model simulation test device of the existing tunnel. The model simulation test box is filled with rock and soil (such as soft soil), and the first tunnel model of the existing tunnel is built in the rock and soil. After the soil is compacted, the first tunnel model is erected between the originating hole and the receiving hole at both ends of the model simulation test box, and the second tunnel model is set in the model simulation test box and below the first tunnel model, and the second tunnel model is The wire rope pulled by the winch is set as the driving mechanism, and the second tunnel model is moved from the starting hole to the receiving hole by the wire rope traction. During the soft soil...
