Problems solved by technology

[0005] Temporary support is time-consuming and laborious, cannot be moved, and the reinforcement is generally heavy. It cannot be supported by lifting vehicles in the tunnel section after construction, and it is inconvenient to use lifting vehicles, which restricts the progress of construction. Simple methods are easy to damage personal safety.

specific Embodiment

[0023] Such as Figure 1 to Figure 5 As shown, it includes trackless walking system, main structure, rotating system, telescopic system, grabbing system, adjustment system and working platform, etc. The equipment travels to the reinforcement position through the trackless walking device, and the grabbing system is rotated to the lower part and the site through the rotating system. The reinforcement is connected and rotated to an appropriate position, the telescopic system is stretched out and aligned, and the adjustment system is precisely adjusted, and the operator installs the structure on the working platform. It can realize the section reinforcement before and after the operation of the subway. The reinforcement equipment has a simple structure, beautiful style, convenient construction, and no need to set up temporary supports and tracks.

[0024] The rotation system includes: a rotation mechanism and a telescopic system; the rotation mechanism can rotate the reinforcement...

Abstract

The invention discloses a metro circular-arc-shaped section reinforcing construction apparatus. The metro circular-arc-shaped section reinforcing construction apparatus comprises a main structure; traveling systems are arranged on the two sides of the lower part of the main structure; a rotating system is arranged in the middle part of the main structure; telescopic systems are arranged on the two ends of the rotating system, respectively; a gripping system and an adjustment system are arranged on the outer ends of the telescopic systems; a working platform is arranged on the upper part of the main structure. The metro circular-arc-shaped section reinforcing construction apparatus is capable of realizing section reinforcements before and after the operation of the metro, and is simple in structure, attractive in appearance and convenient for construction without temporary support and rail.

Description

technical field [0001] The invention relates to a section reinforcement technology of a subway arc-shaped tunnel, in particular to construction equipment for strengthening a subway arc-shaped section. Background technique [0002] At present, most tunnels are excavated by shield tunneling, and most of the tunnel sections are arc-shaped, and the construction fields involve railways and subways. After the segment is installed, especially during the operation of the subway, if there is a problem, the section may be reinforced. [0003] In the prior art, there is no reinforcement equipment for installing structures to complete this work. Much of this is done with temporary support structures. [0004] There are at least the following disadvantages in the above-mentioned prior art: [0005] The use of temporary supports is time-consuming and laborious, and cannot be moved. The reinforcements are generally heavy. In the tunnel section after construction, the lifting vehicles ca...
