The specific embodiment:
Cast-in-place inverted arch lining trolley and a storage concrete curing system tunneling synchronous with TBM, concrete structure and the course of work are:
1, as Fig. 1, before inverted arch (7) lining cutting, steel sleeper (2) is by the bottom of being attached thereto the dismountable column (1) connecing and being supported on hole, and rail (3) is laid on steel sleeper (2).Stable for guaranteeing steel sleeper (2) and rail (3), between steel sleeper, can add dowel.
2, as Fig. 2, after inverted arch (7) lining cutting, it is upper that steel sleeper (2) is laid immediately on inverted arch (7), can add in steel sleeper both sides cross binding and fix to guarantee position, steel sleeper left and right.
3, as Fig. 3,4,5,6,7 cast-in-place inverted arch synchronization lining chassis are mainly comprised of crane span structure, limit mould template (10) and vertical support system.Crane span structure crossbeam (18), crane span structure longeron (16) are connected to overall structure by welding manner; Limit mould (10) is arranged on crane span structure by oil cylinder (11) and leading screw (12); Vertically support (8) and form overall structure by thread bush (17) and support stringer (9), for chassis and curing system provide bearing reaction, for the walking of chassis and curing system provides track, support stringer (9) is chassis and curing system walking rails simultaneously.For accurately locating crane span structure horizontal level, horizontal leading screw (13) is set respectively in crane span structure both sides.
4, as Fig. 3-10, because the rail on chassis and curing system (19) position is higher than rail in hole (3), ramp (26) and rear ramp (28) before being therefore provided with respectively before and after this system.The design grade in ramp, requires the maximum gradient that can adapt to selected traction locomotive to adapt, and avoids normally moving because tractive force and brake force deficiency affect rail haulage device.
5, as Fig. 8,9,10, on chassis and curing system, single-line railway is set, and four rail three lines or four rail two-wire tracks (just list in accompanying drawing and understand four rail three-wire system tracks in hole) are set in hole, therefore, on curing system, be provided with one group of Y-shaped railroad switch.Owing to will keeping suitable distance between inverted arch construction and TBM, the two next-door neighbour can produce larger interference, and distance is oversize can be increased again cost and affect operating speed, thereby in chassis the place ahead, track switch is not set.
6, as Fig. 8,9,10, the length in concreting district, the constuction joint designed distance allowing according to engineering construction figure is determined, but must guarantee to build every day in the situation an of mould (or three days two moulds), the monthly average drilling depth of inverted arch speed of application and TBM driving speed is basic quite and leave certain surplus.32m signal is pressed in accompanying drawing pouring area.Maintenance section length, the intensity and the construction speed target setting age of concrete allowing according to engineering construction figure.
7, as Fig. 8,9,10, chassis and curing system need suitable segmentation, adopt pin to connect, to adapt to the requirement of Tunnel Design curve between each section.
8,, during concreting, be pumped into mould, internal vibration, horizontal segment surface adopt walking beam vibrate, semi-automatic or manually wipe one's face, both sides rely on template contral.
9, during the demoulding, first separate removing template leading screw (12), recycling oil cylinder (11) promotes limit mould.
10, as Fig. 3-10, before chassis and curing system move, in the place ahead, front ramp (26), place support stringer (9), and be connected with steel sleeper (2) with buckle, remove being connected between steel sleeper column (1) and steel sleeper (2), install and vertically support (8), utilize lift mechanism lifts ramp, forward and backward ramp, make front ramp (26), rear ramp (28) depart from rail (3) in hole.When vertically supporting (8) and installing, vertically supporting the upper installing sleeve of turret head (24), utilize crank rotary vertically allotment support (8) and reach design height, with rail (3) in this pushing tow support stringer (9) and steel sleeper (2), hole, jointly moving up.
11, as Fig. 8-10, on column truss (15), be provided with hoist engine and fixed pulley, forward and backward ramp promotes and promotes forward and backward ramp (26,28) by wire rope (25,29).
12,, for reducing the size of chassis and curing system walking mechanism, can adopt hydraulic motor, planetary gear reduction box to drive.
13,, as Fig. 3,4,5, when chassis and curing system walking, on the BOGEY WHEEL of the left and right sides (23) support, be equipped with positive stop lug boss (22).
14, after chassis and curing system traveling put in place, at rear portion, rear ramp (28), remove immediately vertical support (8) and the support stringer (9) of exposure, and be placed on curing system upper brace, treat to be installed to the place ahead, front ramp (26) before trolley running.Meanwhile, the hole that requires shutoff vertical support (8) to form in inverted arch (7) concrete according to job specfication in time.
15, support stringer (9) adopts segment design, and every segment length and concreting length match, and in accompanying drawing, concreting length is 32m, and the length of support stringer (9) can be designed to 8m.For reducing labour intensity, improving work efficiency, the configurable flat car with crane on vehicle, in order to collect rear, rear ramp (28) support stringer (9), in the place ahead, front ramp (26), put support stringer (9).
The present invention can synchronously complete cast-in-place inverted arch lining construction when TBM tunnels, and guarantees that the concrete that does not reach age strength does not carry; Compare soon with laying prefabricated inverted arch, constuction joint greatly reduces, cavitation quality significantly improves, and construction cost obviously reduces; Compare with the cast-in-place inverted arch of constructing after tunnel holing through, the duration significantly reduces, the corresponding reduction of construction cost.
