Abstract
The invention discloses a continuous construction method for a tunnel emergency parking strip cast-in-situ lining by quickly disassembling and assembling a trolley. The continuous construction method comprises the steps that (1) the trolley is assembled according to the design size of a tunnel emergency parking strip; (2) after preliminary construction of the tunnel emergency parking strip is completed, square timber and steel rails are laid on the tunnel emergency parking strip; (3) the whole trolley is disassembled into two semi-range trolley bodies; (4) the two semi-range trolley bodies travel along the steel rails in tandem; (5) the two semi-range trolley bodies are reassembled into the integrated trolley; (6) the tunnel emergency parking strip is subjected to cast-in-situ secondary lining concrete; and (7) after the poured concrete meets the design strength requirement, the integrated trolley is separate into the two semi-range trolley bodies again, and cyclic operation from the step (3) to the step (6) is repeated till secondary lining construction of the tunnel emergency parking strip is completed. By means of the method, the time for disassembling and transferring the formwork trolley can be saved, the construction cost is reduced, and the engineering quality is improved.
Description
Technical field
The cast-in-place liner structure of band the present invention relates to the construction method of bridge tunnel lining cutting, specifically a kind of tunnel are stopped in emergency
Construction method.
Background technology
As highway is more to mountain development, there is numerous major long tunnel, the setting number of the band that wherein stops in emergency
Amount also accordingly increases.As tunnel stops in emergency, band section is bigger than normal reach, and per meter of input ratio normal reach of its two linings construction is served as a contrast
Block is all higher by much and work efficiency is relatively low, often becomes the last operation of constructing tunnel and affects total lever factor.In quality control on construction
Aspect, stop in emergency the concrete common quality defect with two linings, and such as faulting of slab ends, piece, concrete run moding shape, big surface evenness etc. also compared with normal reach
Two linings are many, it is more difficult to control.
The tunnel band lining construction that stops in emergency commonly uses chassis, i.e. formwork jumbo, existing common chassis institute as shown in Figure 1, Figure 2
Show, including parts such as upper die plate assembly 1, bracket column 2, horizontal brace rod 3, yoke crosstie 5, door frame crossbeams 7, chassis is along steel
Rail 18 is walked.
At present both at home and abroad more to the band lining construction that stops in emergency complete using normal reach lining trolley, the band that stops in emergency is widened
Hydraulic jumbo, steel arch-shelf add gang form.Adopt and constructed with upper type, the everywhere in tunnel is stopped in emergency and carries widened section equal
Formwork jumbo need to be broken, then be assembled to next widened section by carborne, time-consuming.Therefore, it is raising
Constructing tunnel level, is necessary for tunnel to be solved and stops in emergency the construction efficiency with secondary lining and improve this biography of construction quality
System problem.
Content of the invention
It is an object of the invention to provide being stopped in emergency continuously applying with cast-in-place lining cutting using quickly tearing conjunction chassis open and carrying out tunnel
Work method, the method can save the time shared by the fractionation of formwork jumbo, transhipment operation, reducing the construction costs, improve engineering
Quality.
The above-mentioned purpose of the present invention is by following technical solution realizing：Close chassis to carry out tunnel urgent using quickly tearing open
The continuous construction method of the cast-in-place lining cutting of lay-by, it is characterised in that the method comprises the steps：
(1) according to tunnel stop in emergency band design size come assembled chassis, chassis include upper die plate assembly, bracket stand
The parts such as post, horizontal brace rod, yoke crosstie, door frame crossbeam, the chassis is made up of symmetrical two half range chassis, and two
Docking pin of the platform half range chassis by upper die plate assembly, yoke crosstie and set by door frame crossbeam correspondence position and to connecting bolt
It is connected as a complete chassis；
(2) after tunnel stop in emergency band complete excavation, preliminary bracing, inverted arch filling construction after, by the lumps of wood and steel rail laying
Stop in emergency band to tunnel；
(3) removal bracket column and horizontal brace rod, while dismounting upper die plate assembly, yoke crosstie are corresponding with door frame crossbeam
Docking pin set by position and to connecting bolt, is rotated down upper die plate assembly, whole chassis is split as two half range platforms
Car；
(4) two half range chassis are one in front and one in back walked along rail, treat that previous half range chassis runs to the band that stops in emergency
After expanding section part, a rear half range chassis is walked on until concordant with previous half range chassis；
(5) through accurately measuring positioning, by two half range chassis by upper die plate assembly, yoke crosstie and door frame crossbeam pair
Answer the docking pin set by position and connecting bolt is reconnected, while bracket column and horizontal brace rod is reset, revert to
One complete chassis；
(6) stop in emergency the splash guard of band to tunnel and reinforcing bar is constructed, pump concrete pours tunnel and stops in emergency
The secondary lining of band, band that tunnel is stopped in emergency carries out cast-in-place secondary lining concrete；
(7) after the concrete for pouring reaches design strength requirement, two half range chassis are separated into again whole chassis,
Repeat step (3) to step (6) circulate operation, using quickly tear open close chassis tunnel is stopped in emergency band carry out continual cast-in-place
Lining construction, until tunnel stops in emergency, the Second Lining Construction of band is finished.
In the present invention, the tunnel refers to bridge tunnel.
Compared with prior art, the present invention has following significant effect：
Formwork jumbo can tear conjunction easily and fast open, by 2 docking pins at per width chassis door frame girder and 9 docking spiral shells
At bolt, and template vault longitudinal direction floor, 20 bolt connections form an entirety, and it is easy to be laborsaving to tear conjunction open, merges or splits once
1～2 day time is only needed, and dismounting with general chassis needs 7 day time ratio to greatly reduce man-hour and manpower and materials.Form stable, applies
Work faulting of slab ends is little, real outer beautiful in concrete.3.5m width job platform is set in chassis one end, stand input is reduced, real chassis is many
Functionalization, after chassis precise positioning, facilitates the accurate installation to reinforcing bar, inspection, overcomes tunnel double-lining reinforcing bar positioning to be forbidden
A difficult problem.
