Abstract

The invention relates to a stratum grouting simulation system, comprising a model load box (2) for containing rock soil, a loading subsystem (3) for loading the rock soil from the top end so as to restore an underground stress field environment, an underground water simulation subsystem (4) for controllably injecting water to the rock soil and discharging the water from the rock soil so as to simulate still water and dynamic water environments, a grouting subsystem (5) for grouting into the rock soil, a data acquisition subsystem (6) for measuring stress, strain and displacement data of the rock soil, and an alarm subsystem (7) for measuring deformation of the model load box (2), pressurizing pressure and grouting pressure and with an alarm function, wherein the side wall of the model load box (2) is provided with a detachable wall plate. The stratum grouting simulation system is lower in cost, and capable of simulating an excavation process, a deeper underground environment, dynamic water and vadose environments.

Description

technical field [0001] The invention relates to the technical field of stratum grouting, in particular to a stratum grouting simulation system. Background technique [0002] With the rapid development of economic globalization, the condition of urban transportation infrastructure, one of the main factors that determine and affect urban competitiveness, is an important support for the level of urban development and civilization, and a material condition for the coordinated development of urban economy and society. With the continuous increase of urban population, the demand for urban transportation infrastructure is also increasing. Since the founding of the People's Republic of China 60 years ago, as the urban population rate has grown from 10% to 50% today, earth-shaking changes have taken place in the construction of urban transportation infrastructure, especially in Beijing, the capital, which has undergone rapid changes. Infrastructure construction has entered a period ...
