Technology.Shield driving is widely used in the Tunnel Engineering such as subway, railway, highway, municipal administration, water power.Recently as city underground
The continuous development built with urban water conservancy, shield machine occupies main status in the construction of subterranean tunnel, becomes underground developing tunnel
The plant equipment that road mainly uses, shield machine produces disturbance to surrounding soil in construction progradation, will deviate from section of jurisdiction
Between the soil body and section of jurisdiction, during shield tail, form the gap of 90～140mm, this will lead to serious ground settlement.Therefore, it is necessary to it is logical
Cross grouting behind shaft or drift lining filling space, control ground settlement, improve the stress of tunnel duct piece.
According to existing result of study, shield tail synchronous grouting can only control the ground settlement after shield tail abjection.However, shield
When the strict material risk engineering of penetrating ground requirement of settlement control or region, before cannot being recovered by back synchronous injection again
The stratum settlement that phase shield-tunneling construction causes.Current arrangement and method for construction is that excavation region is reinforced in advance mostly, and then shield is worn again
Construction more.Although this scheme is safer with respect to this, necessarily require the condition that can there is reinforcing, but due to current city
City ground and superficial part Underground Space Resource have been developed totally, and the material risk region of a lot of shields does not have the bar reinforced in advance
Part, and reinforce in advance and considerably increase construction costs.Therefore, the change based on Suporting structure and risk zones stratum self-condition
Shape control technology is most important.
In time the space between shield shell and excavation stratum should be noted during risk zones shield machine construction
Slurry, and need to coordinate grouting behind shaft or drift lining to control the final settlement after shield-tunneling construction within zone of reasonableness
It is desirable to there is a kind of bull serosity injection device can carry out multiple slip casting operations simultaneously.
