Abstract

The invention discloses an integrated screening, curing and stirring system for shield tunneling muck and slurry. The system comprises a supporting frame, a screening and separating module, a collecting and stirring module and a curing agent adding and homogenizing module, wherein the screening and separating module comprises a square hole screen, a transverse vibration motor, a longitudinal vibration motor and one or more than one spraying pipe; the collecting and stirring module comprises a collecting box and a horizontal stirring device installed in the collecting box, and the collecting box is located below the square hole screen; and the curing agent adding and homogenizing module comprises a slurry pump, a conveying pipe and an automatic curing agent metering and adding device. The integrated screening, curing and stirring system of the invention realizes continuous line production of separation, homogenization, curing and stirring of coarse particles of the shield tunneling muck and the slurry; a curing agent and the slurry are uniformly mixed in the conveying pipe by virtue of the turbulent flow effect formed by the division bars in the conveying pipe, a slurry homogenization pool and a curing and stirring pool do not need to be arranged, and the system is small in occupied space and high in automation degree and provides equipment support for efficient and environment-friendly treatment of the shield tunneling muck.

Description

technical field [0001] The invention relates to the field of shield tunneling equipment, in particular to an integrated system for screening, solidifying and stirring shield tunneling dregs and slurry. Background technique [0002] Shield construction is widely used in urban subway construction in my country due to its advantages of good safety, low impact on the ground and high construction efficiency. The dregs of the shield tunneling machine are improved in places such as the soil warehouse and other locations, and the shield dregs obtained in the end are mostly flow-plastic and contain a large amount of mud, which increases the difficulty of transportation and backfilling, and has road traffic safety, environmental pollution and storage yard problems. Hidden dangers such as landslides are technical problems that need to be solved urgently. [0003] In order to realize the effective treatment of slag from the technical level and cooperate with the treatment process, many t...
