Description
Technical field
What the utility model was related to a kind of lining lining cutting of Tunnel body two performs mechanism, more particularly to a kind of Super-large-section tunnel
Vault two lined steel muscle performs mechanism.
Background technology
When the tunnel of extra-large cross-section is excavated in the rich water rock stratum of highlands, because tunnel cross-section is more than 200 square meters, its
More than 15 meters, span after the completion of preliminary bracing, when carrying out two lining lining constructions, will carry out the lining of vault two to height more than 17 meters
The installation of reinforcing bar, conventional tunnel reinforcement installation method be by vault reinforcing bar on the ground single use deflectable shaping after, then be lifted into
Tunnel vault is installed.Because section span is too big, vault is too high, for large span vault reinforcing bar ground it is disposable into
After type, there is very big difficulty in lifting.Further, since the reinforcing bar installed in vault is bigger than normal due to conducting oneself with dignity, before second pouring, if long
Time exposes in vault, can be deformed due to deadweight, causes successive projects to be normally carried out.
The content of the invention
The utility model performs mechanism there is provided a kind of lined steel muscle of Super-large-section tunnel vault two, solves extra-large cross-section tunnel
The technical problem of road vault reinforcing bar installation difficulty.
The utility model is to solve above technical problem by the following technical programs：
A kind of lined steel muscle of Super-large-section tunnel vault two performs mechanism, including large cross section excavation hole body profile, in big cross section
Two lined steel muscle colligation chassis are provided with excavation hole body profile, crown is respectively arranged with the top surface of two lined steel muscle colligation chassis
Leading screw and crown reinforcing bar right support leading screw are supported in reinforcing bar left support leading screw, crown reinforcing bar, in crown reinforcing bar left support leading screw
Top is provided with left longitudinal reinforcement support frame, longitudinal reinforcement support frame in supporting the top of leading screw to be provided with crown reinforcing bar,
The top of crown reinforcing bar right support leading screw is provided with right longitudinal reinforcement support frame, arch is provided with middle longitudinal reinforcement support frame
Graduation apparatus in the spacing of reinforcement of top, is provided with vault spacing of reinforcement left scale table, in right longitudinal steel on left longitudinal reinforcement support frame
The right graduation apparatus of vault spacing of reinforcement is provided with muscle support frame, on left longitudinal reinforcement support frame, middle longitudinal reinforcement support frame and the right side
The vault reinforcing bar that solder joint is welded together is provided between longitudinal reinforcement support frame.
Anchor pole is provided with vault rock mass, anchor pole links together with vault reinforcing bar；The abutment wall reinforcing bar of segmentation is to pass through
Branch sleeve constitutes abutment wall reinforcing bar.
The utility model scene materials, are performed easily, that is, saved cost, and the Forming Quality of vault reinforcing bar is improve again,
Greatly save the duration.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is A-A in Fig. 1 to sectional view.
Specific embodiment
The utility model is described in detail below in conjunction with the accompanying drawings：
A kind of lined steel muscle of Super-large-section tunnel vault two performs mechanism, including large cross section excavation hole body profile 1, in big cross section
Excavate and be provided with two lined steel muscle colligation chassis 2 in hole body profile 1, be respectively arranged with the top surface of two lined steel muscle colligation chassis 2
Leading screw 4 and crown reinforcing bar right support leading screw 5 are supported in crown reinforcing bar left support leading screw 3, crown reinforcing bar, in crown reinforcing bar left support
The top of leading screw 3 is provided with left longitudinal reinforcement support frame, longitudinal reinforcement in supporting the top of leading screw 4 to be provided with crown reinforcing bar
Support frame 11, right longitudinal reinforcement support frame is provided with the top of crown reinforcing bar right support leading screw 5, according to the height of vault, can
The purpose of regulation longitudinal reinforcement support frame height is reached by rotating threaded shaft, is provided with middle longitudinal reinforcement support frame 11
Graduation apparatus 12 in vault spacing of reinforcement, is provided with vault spacing of reinforcement left scale table on left longitudinal reinforcement support frame, vertical on the right side
To the right graduation apparatus of vault spacing of reinforcement is provided with means for supporting reinforcement steel bar, in left longitudinal reinforcement support frame, middle longitudinal reinforcement support frame
The vault reinforcing bar 6 that solder joint 7 is welded together, segmental hoisting to arch are provided between 11 and right longitudinal reinforcement support frame
The reinforcing bar on top can be accurately positioned on the position of laying according to vault reinforcing bar interval scale table, and colligation is carried out after being welded to connect.
Anchor pole 8 is provided with vault rock mass, the purpose of vault rock mass, and anchor pole 8 and vault reinforcing bar 6 are reinforced to reach
After connection, playing prevents vault reinforcing bar due to deformation induced by gravity；The abutment wall reinforcing bar of segmentation is to constitute abutment wall steel by branch sleeve 10
Muscle 9, so as to solve the problems, such as that section is too high.
Overall invention thinking of the present utility model is the setting vault formed reinforcing steel bars fixing mould on reinforcing steel bar-binding bench car, i.e.,
Leading screw and longitudinal reinforcement support frame, by the vault steel bar segmentation of large span after the bending of ground, then are lifted into reinforcing steel bar-binding bench car
Welding fabrication in the vault formed reinforcing steel bars fixing mould of upper setting, vault formed reinforcing steel bars fixing mould play supporting welding shaping and
The effect of fixed vault reinforcement location, improves the quality and efficiency of vault formed reinforcing steel bars, while liftable vault reinforcing bar is solid
Fixed mold can adapt to the laying requirement of different height vault reinforcing bars by the regulation for lifting；In addition, by hole body wall and arch
Embedded bar anchor pole in top, these embedded bar anchor poles are fixedly connected with two lined steel muscle, overcome reinforcing bar of growing up and are easily deformed
Defect, improve the colligation intensity of the lined steel muscle of extra-large cross-section two.
