It is that the anti-floating power R in tunnel is insufficiently resistant to the floating being subject in shield tunnel construction, the reason for tunnel upward floating
Power F, i.e. R<F.Buoyancy F is main to be wrapped up section of jurisdiction by the liquid such as underground water and grouting serous fluid and is produced, and anti-floating power R is main by current
The weight W in excavation section tunnel1With upper earthing weight W2Constituted.The Analysis on Mechanism of tunnel upward floating and substantial amounts of engineering practice show,
The slurries that one section of tunnel after shield tail most easily occurs on the outside of rising phenomenon, shield tail section tunnel do not solidify fully, now slurries pair
Buoyancy F has certain contribution；Growth over time, grout cures form stable water barrier on the outside of tunnel, now starch
Liquid confrontation buoyancy R has certain contribution.Therefore, the control key that tunnel under construction floats is to carry out the control close to shield tail section tunnel
Floating measure processed.For the weight W of given tunnel line style, thereon earthing2Substantially fixed, anti-floating power R increase can only
Weight W from increase tunnel1To start with, therefore, the floating control device proposed by the present invention suitable for class rectangle shield tunnel,
Purpose is directly to increase anti-floating power R, the adverse effect for effectively alleviating or avoiding tunnel structure to float.
