Description
Technical field
The present invention relates to shield tunnel, in particular to a kind of novel shield balance originating and reception sleeve arrangement.
Background technique
Shield and pipe jacking tunnel engineering method are most widely used and most important engineering technology in current construction of underground tunnel,
Has the advantages that safety, quick, quality control and construction environment is good.Originating and receiving for shield machine and push-bench is always shield
Heavy difficult point in constructing tunnel is even more especially risk control weak, shield and push pipe are originated and received in water rich strata
Difficult point.Using steel bushing balance originating and a kind of technology that shield machine is new opplication in recent years is received, core technology is to adopt
It is mounted at portal with a reusable sealing steel bushing, by filling sand and water and is pressurizeed, form one and portal
The environment that the natural Water And Earth Pressures in end point balance each other, shield machine do not have water and soil pressure at one originating and be equivalent in receive process
It is completed in the environment of power mutation, to ensure that safety.Steel bushing balance originating has obtained in constructing metro tunnel with reception
Application.
From the above it can be seen that keeping the Water And Earth Pressures in steel bushing to balance each other with the natural Water And Earth Pressures in portal end point is
Steel bushing balance originating and one of the key for receiving success.But it is rigid structure since steel bushing is all steel material, and point
It is assembled for 3~4 pieces, each piecemeal of steel bushing inevitably occurs centainly in transport, lifting and use process
Deformation, causes piecemeal seam crossing not can guarantee closely connected, so that sealing performance is greatly reduced, so that leak and gas leakage, cannot keep
Water And Earth Pressures in sleeve.
In addition steel bushing use full steel structure, there is problems: weight and volume is larger, transport and assembly be not easy,
Processing is complicated and cost is higher.
Therefore it is very necessary for designing a set of sleeve arrangement easy, that sealing performance is excellent.
Patent of invention content
Technical problem to be solved by the invention is to provide a kind of novel shield balance originating and sleeve arrangement is received, to have
Effect avoids leakproofness difference present in the steel bushing that is widely used at present and the high problem of complexity, saves investment, guarantees shield
The safety of export & import.
The technical solution adopted by the present invention to solve the technical problems is as follows:
A kind of novel shield balance originating of the invention and sleeve arrangement is received, including is set to active well liner at portal
Transition connection ring on wall, it is characterized in that: the inside of the transition connection ring and the front end of rigid backbone are detachably connected, this is just
Property skeleton rear end be removably connected with grid frame rear cover, flexible water liner is circumferentially around covering rigid backbone inner wall and covering
Grid frame rear cover medial surface；The rigid backbone includes front end annular connecting plate, rear end annular connecting plate and longitudinal gap
It is set to circumferential steel skeleton between the two, further includes circumferentially spaced longitudinal steel skeleton, the both ends of each longitudinal direction steel skeleton
It is detachably connected respectively with front end annular connecting plate, rear end annular connecting plate, circumferential steel skeleton detachably connects with longitudinal steel skeleton
It connects.
The invention has the advantages that principle is simple using the structural system of rigid flexible system, rigid backbone is detachable and group
Dress is easy to transport and assembled, while being sealed using flexible material liner, even if rigid backbone has centainly after a number of uses
Deformation nor affects on the sealing performance and use of sleeve, strong applicability, and can be made according to different shield diameters corresponding big
Small sleeve arrangement has wide promotion prospect；It is easily-deformable to efficiently solve common steel bushing at present, poor sealing performance,
Weight and volume is larger, transport and assembly are not easy, processs complexity and the higher problem of cost, so as to avoid existing steel bushing by
Water And Earth Pressures bad in sealing performance, internal are difficult to maintain caused construction risk to increase, the hair of even surface collapse accident
It is raw.
