Preparation method of transparent soil and shield tunneling simulation system applying transparent soil

Abstract

The invention discloses a preparation method of transparent soil and a shield tunneling simulation system applying the transparent soil, and relates to the technical field of engineering tunnel engineering, and the system comprises a cutter head, a hydraulic rod, a pipe piece, a conveying belt, a liquid conveying pipeline, a liquid discharging pipeline, a waste collecting device and a hydraulic machine. The cutter head is located at the front end of the shield tunneling machine device, the hydraulic rod is connected with the cutter head, the duct piece is located on the surface of the shield tunneling machine device, the liquid conveying pipeline and the liquid discharging pipeline are located in the shield tunneling machine device, the hydraulic machine is located at the tail end of the shield tunneling machine device and supported by a wall, the experiment groove is filled with transparent soil, and the shield tunneling machine device is located in the transparent soil. Visual observation of the tunnel face change process in the shield tunnel excavation grouting process and the grouting slurry dynamic migration process in construction can be achieved, real-time accurate measurement is achieved, and reliable indoor simulation test data are obtained. The device is widely applied to model experiments in the field of geotechnical engineering.
