Abstract
The present invention relates to the class of a tunnel, particularly to a lining structure for a double-round shield construction method tunnel. The lining structure has the shape of two crossed pipes which form a circular ring shape. The lining structure is mainly composed of a big bird block, a small bird block, a column block and more than two standard blocks, wherein the big bird block is positioned at the bottom of a column, the small bird block is positioned at the top of the column, both sides of each of the big bird block and the small bird block are respectively and orderly spliced and connected into a closed ring shape by the standard blocks which form a circular arc shape, and the blocks are fixedly connected. The present invention has the advantages that the underground space is saved, the construction investment is reduced, the construction progress is accelerated, the construction quality is improved, and the economic effect of investment on an urban underground and a road tunnel is greatly improved.
Description
Technical field
The present invention relates to tunnel-like, the liner structure in particularly a kind of double-O-tube shield method tunnel.
Background technology
The development of China's shield structure technology starts from the 1950's, and Shanghai City particularly from the work of establishing in conjunction with subway in 1963, begins to carry out the development work of shield structure technology at weak water bearing ground in the Quaternary Period.Over more than 30 year, " earth pressure balanced shield, EPBS " two main developing stage of shield structure technology has mainly experienced the sixties " grid type shield structure " and eighties, these two kinds of shield structures that drop into the engineering use respectively have tens, built tens of diameters from multi-purpose tunnels such as 3 meters to 11 meters road, power plant, subway, municipal sewer, cables, mainly contain the tunnel, Da Pu road, meridian line tunnel, East Road, Yan'an in Shanghai City and in the tunnel of building, Dalian road, revive roads and tunnels such as East Road; One, No. two lines of subway of operation completely running tunnel, in the Brilliant Pearl Line second phase of the building running tunnel tunnel of awaiting a subway completely.Simultaneously, domestic other metropolitan subways also in construction, mainly contain one, No. two lines of Guangzhou Underground, First Phase Project of Shenzhen Metro, and Line of Nanjing Subway first stage of the project, No. 5 lines of Beijing Metro etc., and all these tunnels are single targe structure running tunnel.The simple structure that this traditional construction method major advantage is the lining cutting annulus, lining cutting assembly unit are convenient, fltting speed is fast or the like, this method is normally once tunneled and is finished a single circular tunnel, circular tunnel more than two if desired, just have only respectively tunneling construction, just therefore caused following drawback: one be two tunnels respectively construction can produce influencing each other of lining deformation; The 2nd, for the safe spacing (about 1 times of tunnel diameter) that guarantees two tunnels, strengthened the scale of shield structure active well, taken excessive, valuable urban underground space, particularly difficulty of construction is very big in a conned space; Three is to construct at twice in two tunnels, add additional workload such as the conversion of shield structure, dismounting, handling than once construction is big, thereby efficiency of construction is low.
Summary of the invention
The objective of the invention is according to above-mentioned the deficiencies in the prior art part, the liner structure in a kind of double-O-tube shield method tunnel is provided, the lining cutting annulus of two single circular tunnels is combined, once just can finish the tunneling construction of uplink and downlink running tunnel by a double-O-tube shield.
The object of the invention realizes being finished by following technical scheme:
Feature of the present invention is, the shape of this liner structure is two crossing circular pipelines, mainly constitute by big flying bird piece, little flying bird piece, column piece and the calibrated bolck more than two, wherein big flying bird piece is positioned at the bottom of column, little flying bird piece is positioned at the top of column, the both sides of large and small flying bird piece respectively by be circular-arc calibrated bolck successively assembly unit connect into closed circular, fixedly connected between piece and the piece.Alleged fixedly connected can be that pre-buried cast iron hand hole and nut connect with the short straight bolt of single head; Also can be that curved bolt is fixedlyed connected with nut with curved bolt hole by the boot-shaped hand hole that two pieces are reserved respectively; Also can be that straight bolt is fixedlyed connected with nut with straight bolt hole by the trapezoidal hand hole that two pieces are reserved respectively.
Two circular pipelines among the present invention intersect the location and depend on its diameter, and common two circle ring center are apart from being R-2R, and R is the outer radius of circular tunnel.
Liner structure of the present invention is connected connection just can become two circular tunnels.
Advantage of the present invention is, can save the underground space, reduces construction investment, speed up the work, improves construction quality, can improve the economic benefit of city underground, roads and tunnels investment greatly.

The specific embodiment
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
Shown in Fig. 1-12, always represent respectively: big flying bird piece (1), little flying bird piece (2), column piece (3), calibrated bolck (4), pre-buried cast iron hand hole (5), nut (6), boot-shaped hand hole (7), curved bolt hole (8), trapezoidal hand hole (9), straight bolt hole (10) with reference to label 1-10.
The shape of the described liner structure of present embodiment is two crossing circular pipelines, mainly constitute by big flying bird piece (1), little flying bird piece (2), column piece (3) and eight calibrated bolcks (4), wherein big flying bird piece (1) is positioned at the bottom of column (3), little flying bird piece (2) is positioned at the top of column (3), the both sides of large and small flying bird piece (1) (2) respectively by be circular-arc calibrated bolck (4) successively assembly unit connect into closed circular, fixedly connected between piece and the piece.Alleged fixedly connected can be that pre-buried cast iron hand hole (5) and nut (6) connect as Figure 10 with the short straight bolt of single head; Also can be that curved bolt is fixedlyed connected as Figure 11 with nut with curved bolt hole (8) by the boot-shaped hand hole (7) that two pieces are reserved respectively; Also can be that straight bolt is fixedlyed connected as Figure 12 with nut with straight bolt hole (10) by the trapezoidal hand hole (9) that two pieces are reserved respectively.
