Anti-caking system and anti-caking method for mudstone stratum shield mud cake

Abstract

The invention belongs to the technical field of tunnel construction, and discloses an anti-caking system and an anti-caking method for a mudstone stratum shield mud cake. The anti-caking system for the mudstone stratum shield mud cake comprises a construction information acquisition module, a tunnel path analysis module, a geological analysis module, a central control module, a geological model construction module, a tunnel path implantation module, a tunnel construction model analysis module, a shield tunneling machine parameter acquisition module, a positioning module, a mud cake monitoringmodule and a mud cake cleaning module. According to the anti-caking system and the anti-caking method for the mudstone stratum shield mud cake, planning is carried out on the geology and a construction route of a construction area, geology analysis in tunnel construction can be achieved, the interval of complex geology in tunnel construction is obtained, and anti-caking mud cake treatment of a cutterhead can be conveniently carried out in the interval; and cutterhead monitoring is carried out in a non-complex construction area, cleaning is carried out on the mud cake on the cutterhead in time,and therefore the convenience of tunnel construction is improved, meanwhile, the shield tunneling machine is protected, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a mud cake anti-caking system and an anti-caking method for shield tunneling in mudstone formations. Background technique [0002] At present: shield tunnel boring machine, referred to as shield machine, is a special construction machine for tunnel excavation. body, transportation of soil muck, assembly of tunnel lining, measurement guidance and deviation correction and other functions, involving geology, civil engineering, machinery, mechanics, hydraulics, electricity, control, measurement and other disciplines and technologies, and "tailor-made" according to different geology Designed and manufactured with extremely high reliability requirements. Shield boring machines have been widely used in subway, railway, highway, municipal, hydropower and other tunnel projects. [0003] When the shield tunnel boring machine is used, in certain strata, such as cla...

AI Technical Summary

Problems solved by technology

[0003] When the shield tunnel boring machine is used, in certain strata, such as clay and mudstone strata, during the construction process of the shield, the cutter head panel will be covered with mud cake, and the cutter cannot effectively cut the soil layer, resulting in low excavation efficiency and stratum disturbance. Large, and the long-term friction between the mud cake and the formation will generate a lot of heat, which will easily cause the main bearing seal to fail

At present, there is no automatic detection and cleaning scheme for mud cake, and it is impossible to realize the anti-mud cake of shield tunneling in mudstone formation, which affects tunnel construction

[0004] Through the above analysis, the existing problems and defects of the existing technology are: currently there is no automatic detection and cleaning scheme for mud cake, and it is impossible to realize the anti-mud cake of shield tunneling in mudstone formation, which affects tunnel construction
