Abstract
The invention discloses the water-stopping method of a kind of shield duct piece and cast-in-place concrete contact site, carry out as steps described below: after the first step, tunnel shield driving complete, after shield duct piece lining cutting is firm, rubber O-ring seal is placed in the ring seal groove of described shield duct piece end face, then described rubber O-ring seal is fixed with spill steel disc and expansion bolt, is pressed in described ring seal groove, it is ensured that rubber O-ring seal is fully compacted；Second step, carrying out pouring of tunnel cast-in-place concrete lining cutting, casting process makes between cast-in-place concrete lining cutting and shield duct piece end face along the most reserved seam of tunnel；3rd step, in described seam from described rubber O-ring seal one end to tunnel central axial direction successively filling polyethylene board, polysulfide sealant and cement mortar.The invention has the advantages that the sealing problem successfully solved between shield duct piece and cast-in-place concrete lining cutting, easy construction simultaneously, stagnant water effect is preferable.
Description
Technical field
The present invention relates to water-stopping method, especially relate to the water-stopping method of shield duct piece and cast-in-place concrete contact site.
Background technology
Use Shield TBM (TBM) tunnel constructed, owing to construction requirement and tunnel structure need, it usually needs in position construction cast-in-place concrete lining cutting such as the import and export of tunnel or the junctions boring quick-fried section and shield machine construction section.This cast-in-place concrete lining cutting often to be constructed after shield duct piece is installed, and therefore, between shield duct piece and cast-in-place concrete lining cutting, sealing just becomes a difficult problem.In engineering construction, traditional water-stopping method be in concrete pre-buried copper sheet or PVC waterstop member to reach sealing purpose, but owing to shield duct piece is the sizing finished product using fixing mould to produce, impossible embedded water stop component, so traditional concrete water-stopping method is unsuitable for the sealing construction of shield duct piece and cast-in-place concrete lining cutting contact site.
Summary of the invention
Present invention aim at the water-stopping method providing a kind of shield duct piece with cast-in-place concrete contact site.
For achieving the above object, the present invention takes following technical proposals:
Shield duct piece of the present invention and the water-stopping method of cast-in-place concrete contact site, carried out as steps described below:
After the first step, tunnel shield driving complete, after shield duct piece lining cutting is firm, rubber O-ring seal is placed in the ring seal groove of described shield duct piece end face, then described rubber O-ring seal is fixed with spill steel disc and expansion bolt, is pressed in described ring seal groove, it is ensured that rubber O-ring seal is fully compacted；
Second step, carrying out pouring of tunnel cast-in-place concrete lining cutting, casting process makes between cast-in-place concrete lining cutting and shield duct piece end face along the most reserved seam of tunnel；
3rd step, in described seam from described rubber O-ring seal one end to tunnel central axial direction successively filling polyethylene board, polysulfide sealant and cement mortar.
The invention has the advantages that the sealing problem successfully solved between shield duct piece and cast-in-place concrete lining cutting, easy construction simultaneously, stagnant water effect is preferable.
Accompanying drawing explanation
Fig. 1 is the water sealing structure schematic diagram between shield duct piece and cast-in-place concrete lining cutting according to the inventive method enforcement.
Fig. 2 is the I portion structure for amplifying schematic diagram of Fig. 1.
Fig. 3 is that the tunnel section after installing shield duct piece is with reference to figure.
Detailed description of the invention
As Figure 1-3, shield duct piece of the present invention and the water-stopping method of cast-in-place concrete contact site, carry out as steps described below:
After the first step, tunnel 1 shield driving complete, after shield duct piece 2 lining cutting is firm, rubber O-ring seal 4 is placed in ring seal groove 3 on described shield duct piece 1 end face, then fix, in the ring seal groove 3 that is pressed on shield duct piece 2 end face with spill steel disc 5 and 6 rubber O-ring seals 4 of expansion bolt, it is ensured that rubber O-ring seal 4 is fully compacted；
Second step, carrying out pouring of tunnel 1 cast-in-place concrete lining cutting 7, casting process makes between cast-in-place concrete lining cutting 7 and shield duct piece 2 end face along the most reserved seam 8 wide for 10mm of tunnel 1；
3rd step, in described seam 8 from described rubber O-ring seal 4 one end to tunnel central axis 9 direction successively filling polyethylene board 10, polysulfide sealant 11 and cement mortar 12.
Claims (1)
1. a shield duct piece and the water-stopping method of cast-in-place concrete contact site, it is characterised in that: carry out as steps described below:
