Abstract
The invention relates to a double-layer lining shield tunnel duct piece and lining superposed structure. The superposed structure is formed by superposing duct piece linings (1) and reinforced concrete cast-in-place linings (2) of a shield tunnel together, the adjacent duct piece linings (1) are connected by adopting a duct piece connecting bolt (4), a duct piece stressed steel bar (6) arranged in the annular direction of a duct piece and a duct piece tie bar (8) arranged in the radial direction are arranged in each duct piece lining, and a lining stressed steel bar (7) arranged in the annular direction of the lining and a lining tie bar (9) arranged in the radial direction are arranged in each lining (2). The superposed structure is characterized in that: anti-shearing protrusions or sunken pits are reserved on the inner arc surfaces of the duct piece linings. By arranging the superposed double-layer linings, non-uniform settlement of soft soil or the stratum shield tunnel with non-uniform hardness is reduced, waterproof effect and impact resistance to special load are improved, and operation safety of a train is ensured; and the superposed structure has good social and economic benefits.
Description
Technical field
The present invention relates to shield tunnel, relate in particular to a kind of double-deck lining cutting duct pieces of shield tunnel and liner iterative structure, be applicable to and adopt the duct pieces of shield tunnel of double-deck lining cutting and being connected of liner.
Background technology
The domestic shield tunnel of building adopts the example of double-deck lining cutting less at present, the water tunnel that railway lion tunnel, ocean, only wide Shenzhen and Hong Kong and part adopt shield method to build, double-deck lining cutting all has greater advantage aspect fire prevention, waterproof, explosion-proof, antidetonation, the anti-sedimentation, particularly the shield tunnel of building at high intensity Zone, weak soil or hard-soft heterogeneous ground adopts the structural shape of double-deck lining cutting to have many benefits.But all be set to composite construction between existing double-deck lining-built tunnel piping sheet and the liner, i.e. therefore each architectonical between liner and the section of jurisdiction exists following problem:
1, because pipe-plate lining is the prefabricated structure of employing strong concrete, and the surfacing precision is higher, surface, section of jurisdiction cutter hair difficulty, therefore liner and section of jurisdiction adhesion stress are relatively poor, can't effectively form iterative structure, tunnel antidetonation, anti-sedimentation capacity a little less than, ultimate bearing capacity is relatively low.
2, inner lining structure does not participate in load and distributes often only as the deposit structure in tunnel, therefore, causes tunnel segment structure thicker, and economy is relatively poor.
3, liner is that weak shearing resistance is connected with structural plane between the section of jurisdiction, is that structure stress is indeterminate, when load generation great variety, dashes become silted up variations, earthquake etc. as the riverbed, the structural plane destructible, and then be liner destruction.
Summary of the invention
The objective of the invention is weak point at the above-mentioned background technology, a kind of rigidity and resistance to settling energy that can strengthen structure proposed, improve the double-deck lining cutting duct pieces of shield tunnel and the liner iterative structure of the impact of waterproof effect and opposing special load, make it that enough shear resistances are provided between double-layer structure.
For achieving the above object, the present invention adopts following technical scheme: a kind of double-deck lining cutting duct pieces of shield tunnel and liner iterative structure, described iterative structure is the structure that is superimposed together by the pipe-plate lining 1 of shield tunnel and reinforced concrete cast-in-situ liner 2, adopt section of jurisdiction connecting bolt 4 to connect between the adjacent tubes sheet built 1, in each pipe-plate lining, be provided with the section of jurisdiction steel bar stress 6 and the radially section of jurisdiction lacing wire 8 of layout of arranging along the section of jurisdiction circumferential direction, in each liner 2, be provided with the liner steel bar stress 7 and the radially liner lacing wire 9 of layout of arranging along the liner circumferential direction, it is characterized in that, on the intrados of pipe-plate lining, reserve shearing resistance protrusion or recessed pit.
Preferably, welding between section of jurisdiction connecting bolt 4 between the adjacent tubes sheet built 1 and the liner lacing wire 9.
Furtherly, bigger straight bolt, curved bolt or the oblique bolt of described section of jurisdiction connecting bolt 4 employing hand holes.Described section of jurisdiction connecting bolt 4 adopts the bigger straight bolt of hand hole, curved bolt or oblique bolt.
Preferably, at the medial extremity reserved steel bar connector 10 of part section of jurisdiction lacing wire 8, this reinforcing bar connector directly links to each other with liner lacing wire 9.
In such scheme, described shearing resistance protrusion or recessed pit shape of cross section can be square, rectangle, circle, triangle, straight line or curve.
Preferably, in liner 2, liner lacing wire 9 links to each other with liner steel bar stress 7; In pipe-plate lining 1, section of jurisdiction steel bar stress 6 links to each other with section of jurisdiction lacing wire 8.
The present invention with the section of jurisdiction connecting bolt as the carrier that is connected with the liner lacing wire, the part lacing wire of liner and the welding of section of jurisdiction connecting bolt, improve the shear strength between liner and the section of jurisdiction, therefore, this class formation generally adopts bigger straight bolt of hand hole or curved bolt, does not use oblique bolt but also do not limit.
The present invention is the reserved steel bar connector on the inner surface of section of jurisdiction part lacing wire, directly link to each other with the liner lacing wire, connector can be along the seam both sides also full inner surface arrange.
The present invention reserves shearing resistance protrusion or recessed pit on the intrados of section of jurisdiction, strengthen the adhesion stress of liner and section of jurisdiction.
Advantage of the present invention is:
1) the present invention is by being provided with the double-deck lining cutting of superimposed pattern, the differential settlement and the performance that has improved antidetonation, waterproof and the opposing special load impact force in tunnel of weak soil or hard-soft heterogeneous ground shield tunnel have been reduced, guarantee the operation security in tunnel, had good social benefit.
2) owing to adopted iterative structure, suitably the thickness of attenuate shield duct piece lining cutting has high economic benefit.
3) the present invention only carries out among a small circle transformation to existing section of jurisdiction, utilize existing hand hole, bolt, and part transform steel form etc., can not increase too many material, cost is lower.
