Test model for simulating underground engineering construction

Abstract

The invention discloses a test model for simulating underground engineering construction, and relates to the technical field of engineering construction experiment devices, the test model comprises a rock-soil body model, an assembly mechanism and a model replacement mechanism, a fixing shaft is inserted in a connecting groove, a pull block abuts against the outer side of a vertical rod, and pressing rods are inserted into the two sides of a connecting plate. By arranging the sleeve rods, the connecting grooves, the fixing shafts, the guide blocks, the inserting rods and the fixing bolts, building can be completed only through simple operation construction, manpower and material resources are saved, by arranging the sliding sleeves, the elastic rods, the connecting holes, the fixing blocks and the pull rods, the mechanism can reinforce the main body frame, meanwhile, building can be more time-saving and labor-saving, the rock-soil body model is convenient and rapid to replace by arranging the supporting frame, the clamping block and the rolling roller, and the rock-soil body model can be more convenient and rapid to fix and mount by arranging the compression bolt, the pressing rod, the pressing plate, the rotating block, the second hydraulic rod and the fixing plate.

Description

technical field [0001] The invention relates to the technical field of engineering construction experiment devices, in particular to a test model for simulating underground engineering construction. Background technique [0002] With the continuous acceleration of my country's urbanization process and the continuous enhancement of the country's comprehensive strength, the progress and utilization of urban underground space technology are also developing rapidly. In order to coordinate all kinds of municipal planning, the method of synchronous construction of underground comprehensive pipe gallery and urban subway can avoid repeated excavation of the road surface from hindering traffic, greatly improve construction efficiency, reduce waste of resources, and minimize damage to The influence of citizens’ lives, in the construction of underground engineering, sometimes it is necessary to simulate the test model for underground engineering construction to conduct simulation exper...

AI Technical Summary

Problems solved by technology

[0003] At present, the construction and disassembly of the existing test models for simulating underground engineering construction are complicated and cumbersome, requiring a lot of manpower and material resources to complete, which has a certain impact on the follow-up work efficiency, and the rock and soil models used in the experiments are not It is convenient to replace, the process is time-consuming and laborious, and it is not easy to use, so there is still room for improvement. The existing test models for simulating underground engineering construction are complicated and cumbersome to build and disassemble, and the rock-soil models used in experiments are insufficient.
