Abstract

A visual quasi-rectangular shield synchronous grouting slurry diffusion mode research platform includes model soil and model slurry both equipped for realizing the indoor visual environmental function, a reduced scale quasi-rectangular shield type synchronous grouting physical process simulation test device and a commercial particle image velocimetry system, wherein the model soil and model slurry are equipped by transparent soil, the model soil is used for realizing the visual shield environment, and the model slurry is diffused by the reduced scale quasi-rectangular shield type synchronous grouting physical process simulation test device. The invention further discloses application of the platform, the visual environment is utilized to dynamically simulate and accurately observe the whole process of synchronous grouting of a quasi-rectangular shield machine, a convenient research platform is provided for the layout scheme research of grouting pipes of the quasi-rectangular shield machine, and a condition is provided for the research of the slurry diffusion mode of quasi-rectangular shield type synchronous grouting.

Description

technical field [0001] The invention belongs to the field of tunnel and underground engineering, and relates to a similar rectangular shield synchronous grouting technology suitable for tunnel engineering. Background technique [0002] The shield method has been widely used in the construction of underground tunnels in cities at home and abroad because of its advanced construction technology and continuous improvement of construction technology, strong adaptability to the stratum, little impact on the surrounding environment, and not affected by climate and ground traffic. . However, due to the limitation of geological conditions and construction technology, practice shows that the construction of shield method will inevitably disturb the surrounding soil, causing stratum movement, soil stress and changes in mesoscopic structure, etc., which may cause damage to surrounding buildings in severe cases. Damage to property, underground pipelines and other facilities. So far, ma...
