Description
Technical Field
The invention relates to the technical field of shield machine components, in particular to a shield shell outer-wrapping grout stopping device and a grout stopping method of a shield machine.
Background
The shield machine is a special engineering machine for tunneling. The modern shield tunneling machine integrates light, mechanical, electrical, hydraulic, sensing and information technologies, and has the functions of excavating and cutting soil, conveying soil slag, assembling tunnel lining, measuring, guiding, correcting deviation and the like. In the tunneling process, the pipe is reinforced by adopting a synchronous grouting mode behind the wall to prevent the ground surface from settling, but in the grouting process, the injected slurry needs certain fluidity and setting time, and once the slurry stopping effect at the shield tail is poor or the pressure of a shield excavation bin fluctuates, some slurry is lost and the construction efficiency and the stratum settlement control are influenced.
At present, the slurry stopping effect is realized by adopting a mode of welding a slurry stopping plate at the tail of a shield. The slurry stopping mode is low in sealing pressure and poor in slurry stopping effect, and when the shield tunneling machine is applied to the working conditions of large excavation diameter, large burial depth, water pressure and long distance, the slurry stopping plate is easy to wear and lose effectiveness, so that underground water and slurry behind the shield shell are communicated with an excavation surface in series. In addition, the existing shield with the super-large diameter is generally tunneled by adopting a normal-pressure cutter changing cutter head, the flow path of residue soil of the normal-pressure cutter head is long, and a slurry flushing system is difficult to ensure that no dead angle is left to improve the smoothness of slurry circulation, so that the phenomenon of residue accumulation and bin blockage is frequently caused. The unsmooth circulation of the dregs reduces the tunneling efficiency and increases the construction investment of the project. Therefore, the grouting effect of the shield machine shell needs to be improved, and the infiltration and the communication of underground water, synchronous grouting slurry and secondary grouting slurry on the lining side to the excavation bin of the shield machine are effectively prevented. Therefore, when the stratum is stable, the excavation bin can be properly depressurized without causing the shield tail slurry to flow to the excavation bin in series so as to realize half-bin slurry tunneling, improve the circulation of tunneling muck, reduce the tunneling resistance of a cutter head, improve the tunneling efficiency and increase the tunneling speed.
