Problems solved by technology

[0003] The purpose of the present invention is: for existing in the prior art, the combination of inner and outer mold trolleys is used to carry out the construction of large section and large vertical slope cut-and-cut tunnels, the inner mold trolley first enters the construction position to bind the steel bars of the tunnel main body, and the outer mold platform The car needs to wait for a period of time before entering the construction position, which causes waste of construction time and slows down the construction progress. It is not suitable for the construction of emergency projects. A buckle support system and construction for open-cut tunnels are provided. The system, which has a buckle-type bracket, does not affect other construction panels when it is installed or disassembled, so that it can work at multiple points in advance of the trolley at the same time, greatly speeding up the progress of the construction period, good economy, and easy turnover

Embodiment 1

[0063] Such as Figure 1-11 As shown, a coil support system for open-cut tunnels described in this embodiment includes a coil support 1, and a support truss 3 is connected to the support truss 1 on the support truss 3, and the outside of the support truss 3 The support is connected with an arch formwork 2, the arch formwork 2 is adapted to the shape of the inner wall of the tunnel 5, and the support truss 3 includes a main beam 31 arranged along the inner wall of the tunnel 5 and a longitudinal arrangement along the inner wall of the tunnel 5. The secondary beam 32, the main beam 31 is supported and connected with the secondary beam 32, the buckle bracket 1 is supported and connected with the main beam 31, and the arch formwork 2 is connected to the outside of the secondary beam 32, The buckle bracket 1 includes a vertical bar 11, a horizontal bar 12 and a vertical bar 13, the horizontal bar 12 is arranged horizontally along the cross-sectional direction of the tunnel 5, and t...

Embodiment 2

[0105] Such as Figure 12 As shown, a construction system for open-cut tunnels described in this embodiment includes an outer mold trolley 6 and a buckle support system as described in this application, the outer mold trolley 6 and the buckle There is a pouring space for pouring the structure of the tunnel 5 between the support systems.

[0106] Beneficial effects of this embodiment: a construction system for open-cut tunnels described in this application, the outer mold uses the outer mold trolley 6, and the inner mold uses the buckle support system described in the application. The combination of bracket 1, support truss 3 and arch formwork 2 replaces the inner mold trolley. Compared with the inner mold trolley, the buckle-type bracket 1 does not affect other construction panels when it is installed or disassembled, so that the trolley can be advanced Multi-point simultaneous operation greatly speeds up the construction schedule, good economy, and easy turnover. At the same...

Abstract

The invention relates to the technical field of tunnel engineering, in particular to a disc buckling support system and a construction system used for an open-cut tunnel. The disc buckling support system comprises a disc buckling support, wherein the outer side of the disc buckling support is in supporting connection with a supporting truss, the outer side of the supporting truss is in supportingconnection with an arched formwork, and the shape of the arched formwork is adaptive to the shape of the inner wall of the tunnel. According to the disc buckling support system used for the open-cut tunnel, through a principle that the disc buckling support can be split into a plurality of small parts, a combination of the disc buckling support, the supporting truss and the arched formwork is usedfor replacing an inner mold trolley, when the disc buckling support is installed or disassembled, other construction plate blocks are not affected, so that multiple points can be simultaneously operated ahead of the trolley, a plan of days for construction is greatly quickened, and the disc buckling support system exhibits good economic efficiency and is easy in turnover.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a buckle support system and a construction system for open-cut tunnels. Background technique [0002] At present, in the construction of open-cut tunnels with large cross-sections and large longitudinal slopes, the bottom surface of the tunnel is constructed first, and then the upper arched part of the tunnel is constructed. When entering the next construction position after the construction is completed, it is necessary to carry out the operation of the inner formwork trolley first to bind the steel bars of the tunnel main body. At this time, the outer formwork trolley needs to wait for a period of time before entering the construction position, resulting in a waste of construction time. Slow down the construction progress, it is not suitable for the construction of emergency works. Contents of the invention [0003] The purpose of the present invention is: for exi...
