Description
Technical field
The invention belongs to shield tunnel construction building material technical fields, and in particular to one kind being suitable for large-diameter shield tunnel
Road simultaneous grouting slurry.
Background technology
In shield tunneling process, since the outer diameter of cutterhead and shield shell is more than the outer diameter of lining segment, deviate from shield tail in section of jurisdiction
Afterwards, certain building gap can be formed between section of jurisdiction and surrounding soil.Shield synchronization slip casting technology refers to deviating from shield tail in section of jurisdiction
While, in appropriate injecting paste material under a certain pressure pressure injection to shield tail gap, gap is built after filling wall in time, to
Stratum settlement formation caused by shield-tunneling construction is efficiently controlled, and mortar depositing construction is convenient, is widely adopted at present.With city
The rapid development of city's rail traffic, shield tunnel application of construction method is more and more extensive, and shield diameter also increases from common 6m or so
To 10m or more.To give full play to the technological merit of major diameter (10m or more) shield, synchronous grouting fills gap, reduction earth's surface is sunk
It drops slurries setting time that is most important, and shortening synchronous grouting, relatively early performance grouting behind shaft or drift lining support action is more crucial.
Simultaneous grouting slurry is divided into single slurry and dual slurry in shield tunnel construction at present.Single slurry is easy for construction, holds
Manageability, thus existing shield tunnel synchronous grouting mostly uses single slurry.But single slurry setting time is long, early strength is with after
Phase intensity is all relatively low, and shrinking percentage is higher, and ground settlement cannot be timely and effectively controlled especially for large diameter shield tunnel.It is existing
Some dual slurries have opposite single slurry shorter setting time and higher intensity, however existing dual slurry is in work progress
In easily isolation, easy plugging and construction it is complicated, be unfavorable for long distance construction.And for major diameter (10m) shield in work progress
In stratum settlement reaction rate faster, there is presently no a kind of dual liquid type slurries of high comprehensive performance can be to major diameter shield
Sedimentation caused by structure is constructed has preferable control effect.
Therefore in order to meet large diameter shield tunnel settlement Control, when needing one kind and being not easy to isolate, be not easy plugging, condensation
Between short and high intensity simultaneous grouting slurry.
