Present subway, get down the highway and build with railway traffic channel nationwide like a raging fire, underground traffic has fortune
Defeated high-efficient, the advantages that carrying capacity is big, becomes and alleviates the effective way that traffic transports pressure and Accelerating Regional Economic construction.Shield
Method is the construction that subterranean tunnel most generallys use, during shield-tunneling construction, drawn into tunneling process due to shield around
The disturbance of ground layer soil body is to generate excess pore water pressure, if Super-void Water Pressure dissipates not in time around tunnel duct piece, it will
Cause duct piece float upward, ground the environmental effects such as significantly to settle, certain hidden danger is caused to tunnel safety.
Because the shield tunnel dangerous situation that section of jurisdiction leakage causes happens occasionally.When on 2 7th, 2018 evenings 7, Foshan subway 2
Handing over two boat office bid section Lutao lake to lakes to gush in line first stage of the project, the burst of the shield section building site You Xian is permeable, and operating worker attempts leak stopping
Have no resolution, until at night 8 when 40 divide or so, live water permeable area expands, and causes tunnel duct piece to deform and damaged, causes ground season West China
The more meters of sections Lu Sanshi collapse.Through investigating, accident segment occurred is there are deep water-rich silty sand layers and closes on highly permeable medium-sand seam,
Underground water has pressure-bearing property, and the permeable accident for gushing blowout mud collapsing easily occurs when shield machine passes through the location.
Currently used drainage measure is to take unimpeded combination method, according to the size of leak location water leakage, to part
Leakage point and the small location of water leakage are done diversion pipe and are drained, and lead to and are then exhausted from tunnel in the catch basin of tunnel floor.To leakage
It takes segmentation turk conduit to infuse special slurries and reinforces to form water blockoff area in the location that water is big and area is big.However this method
It can be due to the asynchronous initiation sediment failure of the work progress of slip casting, draining.And slip casting and draining are separately laid, and are constructed more multiple
It is miscellaneous.
Summary of the invention
