Description
Technical field
The present invention relates to Tunnel Engineering field, and in particular to a kind of duct pieces of shield tunnel sealing gasket.
Background technology
Shield tunnel construction method refers to use shield machine, the unstability while control excavation face and surrounding soil do not cave in,
While carry out tunnel piercing, slag tap, and segment assembly forms lining cutting, implements grouting behind shaft or drift lining in machine, it is native around so as to not disturb
Body and the method for building tunnel, because its is safe and environment-friendly, mechanization degree is high, need not typically suspend traffic, not climate condition shadow
Ring the advantages that and be widely used in the Tunnel Engineering such as urban track traffic, highway, water conservancy.
Shield tunnel is mostly to be assembled by prefabricated reinforced concrete segment and be aided with the annular shape that bolt connection is formed at present
Structure, block indirection seam waterproof are realized by sealing gasket.Per endless tube piece typically by one piece of block that binds, two pieces of adjacent blocks, three pieces of standards
Block composition, assembly order is that left and right alternating installs calibrated bolck, left and right alternating installation adjacent block, installs the block that binds successively, wherein sealing
Jacking block assembling method is first longitudinal lap joint 1/3, and then assembling machine radial direction ejection to precalculated position is longitudinally inserted into again.
The waterproof method of shield tunnel includes impermeable structure and other attached measures, such as waterproof coating, section of jurisdiction outside section of jurisdiction
Seam waterproof, do secondary lining etc., wherein using at segment joint as waterproof emphasis.The countermeasure of usual segments' joints waterproofing is to use
Encapsulant, a cyclic sealing gasket is mainly set in the sealed groove of section of jurisdiction surrounding, treated on latter two section of jurisdiction of pipe sheet assembling
Sealing gasket mutually extrude, sealing is come with contact surface compression.
Bind block be assemblied into lining cutting closure cyclization process, bound in the block insertion process that binds block sealing gasket and both sides
Mutual extruding, friction will be inevitably produced between adjacent block sealing gasket, sealing gasket movement dislocation is easily caused, extrudes, even
Depart from sealed groove, influence segments' joints waterproofing performance and assembled quality.It is often close in both sides for this problem, pipe sheet assembling
Water-based lubricant is smeared on packing contact surface, to reduce frictional force, but this problem is not can solve still, still has in practice
Bind block assembly when sealing gasket extrusion, seam percolating water phenomenon occur.
The content of the invention
Present invention aims at：It is close on block in the assembled insertion process that shield tunnel binds block, binding at present
Mutually extrude, rub between sealing gasket on packing and both sides adjacent block, easily cause sealing gasket movement dislocation, extrusion, even take off
From sealed groove, the problem of influenceing segments' joints waterproofing performance and assembled quality, there is provided a kind of duct pieces of shield tunnel sealing gasket, should
Sealing gasket can strengthen slide, the anti-plasticating capacity between the sealed groove of section of jurisdiction, can avoid shield tunnel bind block assembly
During sealing gasket slide, extrusion, improve pipe sheet assembling quality and seam waterproof performance.
To achieve these goals, the technical solution adopted by the present invention is：
A kind of duct pieces of shield tunnel sealing gasket, including sealing pad body, the sealing gasket body bottom portion are provided with close with section of jurisdiction
