Response of the Spiral Conveyor Spewing in Water-Rich Sand

Article Preview

Abstract:

Spiral conveyor spewing is a serious danger when the shield tunneling machine crosses water-rich sand stratum. It will lead to the malfunction of dregs discharging and the failure of soil pressure’s effective control. It will be a chief reason to influence construction progress and even cause secondary disaster, which led to the serious destroy of the survival environment, such as ground collapse, water leakage in the tunnel. The danger of spiral conveyor spewing and the countermeasures and the method of the project can be stated by the construction experience in some sections, in order to give some suggestion and references to similar engineering.
