Description
Technical field
The grouting behind shaft or drift lining construction field of immersed tube and FS final spice immersed tube is the utility model is related to, is noted after particularly a kind of immersed tube
Furrow pump line fixing device under pulp-water.
Background technology
The very big large bridge of some spans frequently includes seabed tunnel section, seabed tunnel connected by several immersed tube and
Into the seabed tunnel that the application is related to, in two final immersed tube joints, also plays same in addition to several immersed tube
When connect both sides immersed tube " sandwich immersed tunnel structure "（Also FS final spice is, the FS final spice is also immersed tube, is only one section
More special immersed tube, after this section of immersed tube docks with the immersed tube at its both ends, seabed tunnel insertion）.
Immersed tube（Including " the sandwich immersed tunnel structure "）Installation site seabottom geology structure on, be both provided with correspondingly
Blotter, possess spacing between adjacent blotter, furrow formed, simultaneously because the laying process of blotter（S types are walked
To）, in addition to the big furrow formed below immersed tube joint due to the gap between two blotters, in single rubble
There are several relatively described less small furrows of big furrow at the top of bed course.
If specifically, were not provided with furrow, immersed tube（Including " the sandwich immersed tunnel structure "）Transferring to blotter
When upper, blotter can be extruded to pressure caused by blotter, for below immersed tube joint, the blotter being extruded is then
Waterstop can be moved upward to, the rubble in the excessive then blotter of pressure may bursting waterstop；So institute can be just set
State furrow structure.
But furrow structure is defective, in immersed tube（Including " the sandwich immersed tunnel structure "）In installation process, due to broken
Stone bed course is pressurized, and the geologic structure under blotter or blotter may settle（Such as one reason for this is that lock
The blotter then part rubble that is pressurized may cause the blotter of other parts thinning, shape toward moving in furrow after fixed backfill
Into sedimentation）, at this moment immersed tube（Including " the sandwich immersed tunnel structure "）Installation posture and height be not inconsistent standardization, structure sheet
Body run-off the straight or relative ideal installation site produce the deviation of height（It is relatively low）, it is necessary to adjust again, adjustment difficulty is larger, meeting
The progress and effect of installation are influenceed, especially for FS final spice, it is due to needing both ends while connecting the end of two immersed tube
Portion, the requirement of installation is very high, difficult using the adjustment mode of routine if being supported in installation process for its bottom settles
Degree is very big（For example lift by crane）, efficiency is very low, and Adjustment effect is undesirable.
Secondly, in immersed tube（Including " the sandwich immersed tunnel structure "）It is broken because marine environment influences after installation
Stone bed course may settle, and at this moment, the immersed tube at sedimentation occur（Including " the sandwich immersed tunnel structure "）Upper script by
The power that blotter is shared then is applied on adjacent immersed tube wall by connector, and adjacent immersed tube is bearing portion originally
Sub-support immersed tube（Including " the sandwich immersed tunnel structure "）Power in the case of, the transfer of this power then may to immersed tube and
Adjacent immersed tube link position（Link position including " the sandwich immersed tunnel structure " and adjacent immersed tube）Cause to damage, influence to sink
Pipe（Including " the sandwich immersed tunnel structure "）The stability and service life of joint, cause potential safety hazard.
Meanwhile immersed tube（Including " the sandwich immersed tunnel structure "）After installation, blotter is to immersed tube（Including described
" sandwich immersed tunnel structure "）Support be not present prestressing force or prestressing force it is smaller, immersed tube（Including " the sandwich immersed tube knot
Structure "）To load in use（Vehicle and part external force）Supporting effect it is unexcellent.
So in view of the above-mentioned problems, now implement a kind of immersed tube joint basis post-grouting method（Submit patent Shen on the same day
Please）, it is now desired to it is a kind of to realize in this method device pump line being stably secured transverse in big furrow.
