Description
Technical field
This utility model is related to shield tunnel seam waterproof engineering field, has two pass waterproof sealing more particularly, to a kind of
Sealed waterproof device in the middle part of the duct pieces of shield tunnel of pad at bolt hole.
Background technology
In recent years, with the exploitation successively of China's underground space, and the constantly improve of urban mass transit network, shield
Engineering method with its mechanization degree it is high, speed of application is fast, environmental effect is little the advantages of, in current urban subway tunnel and large-scale water
It is widely adopted in lower Tunnel Engineering.Show according to investigations, shield tunnel percolating water becomes impact shield tunnel safety and operation
One of Major Diseases, particularly with electric power tunnel, effluent tunnel and subway tunnel etc., percolating water is not only to daily operation
Bring heavy potential safety hazard.As high hydraulic pressure gets over the emergence in river or tunnel over strait, single track seam waterproof can not meet
Existing design requirement, even two pass, multi layer waterproof are constantly used in the design of shield duct piece seam waterproof.
According to the long term monitoring and Defect inspection situation of domestic certain subway tunnel, find in investigation, except in lining tube
Piece seam (circumferential weld and longitudinal joint) place occurs outside percolating water, the also generally existing of the seepage disease at bolt hole, shows bolt hole
It is one of main positions that percolating water occurs.But in the design work of existing shield tunnel, at the waterproof of bolt
Reason, generally using processing modes such as slip casting filletings only at bolt hand hole.In Practical Project, shown according to investigation, bolt hand hole
The extensive generally existing of water leakage defect at place, shows that water-proofing treatment mode is not good at existing bolt hole, it would be highly desirable to further perfect,
And carry out targetedly scientific and reasonable design.
The high hydraulic pressure tunnel over strait for more river, and electric power tunnel, water tunnel etc., for segments' joints waterproofing, tool
There are very high waterproof ability and waterproof safety coefficient requirements.Often using the design form of two pass waterproof sealing gasket, by arranging
Twice elastic sealing gasket, to swaging into two pass waterproof defence line, it is ensured that even if segment joint is in the case where side is opened, also can be extremely
Rare one waterproof sealing gasket can bear higher hydraulic pressure.Substantially increase safety coefficient and the waterproof ability of segments' joints waterproofing
Stability.Then, there is connecting bolt in segment joint, there is space between bolt hole and section of jurisdiction, carry out at bolt hand hole
Slip casting closure is processed, and practical situation shows, at bolt hand hole, the general processing mode waterproof effect such as slip casting closure is not good, prevents
Outlet capacity is far smaller than elastic sealing gasket.Therefore, when, in two pass waterproof defence line, first waterproof failure, the lower water of hydraulic pressure effect enter
Enter central cavity, the bolt hole in central cavity is now in into waterproof most fragile position, is hit under hydraulic pressure effect rapidly
Wear, seam integral waterproofing failure, however, second waterproof is in this case, hardly play a role and meaningless.Therefore for
The duct pieces of shield tunnel seam of two pass waterproof, the waterproof at the bolt hole of middle part become the pass that can two pass waterproof effectively play a role
Key, there is no design and the device of this part at present both at home and abroad.
