Description

Arc support erection equipment in cable tunnel Technical Field The utility model relates to the field of tunnel cable support installation, in particular to an arc-shaped support installation device in a cable tunnel. Background In the urban tunnel, the pipe jacking tunnel (the diameter of the prefabricated concrete pipe is generally 2-5 meters), which is convenient to construct, is little in damage to the ground and widely favored by the market, the using amount is more and more, the pipe diameter is also more and more large, and the original diameter is two meters to more than 5 meters. As cable capacities increase, the use areas become wider and the diameters of tunnels become larger, which presents new problems and new difficulties for the installation of brackets supporting cables within cable structures. The construction installation cable support in the tunnel is because the arc structure of tunnel ditch wall causes the personnel to be under construction and brings a plurality of inconveniences, especially in order to make full use of tunnel space, the cable support needs to carry out all-round overall arrangement, and construction installation degree of difficulty is very big. At present, no good auxiliary or installation equipment is provided for the installation of the arc-shaped stand column, the expected effect and efficiency are difficult to achieve through the traditional manual installation, the arc-shaped modeling is difficult to meet the safe operation of the common hoisting machinery, the limited space is limited, the common hoisting machinery is difficult to have a deployment space, particularly, the arc-shaped stand column is installed on an arc wall, the sliding phenomenon can occur, the potential safety hazard is caused, particularly, the arc-shaped stand column is completely attached to the tunnel wall and must be aligned with a certain radian, and the traditional manual installation and mechanical installation basically cannot achieve the purpose of quick and safety of the arc-shaped stand column; Therefore, the equipment for automatically installing the bracket under the special arc-shaped narrow working condition has the advantages of improving the efficiency and reducing the cost for installing the bracket in a tunnel in the future, improving the safety and reliability of the installation, having very high social value and economic value and having a certain supporting effect for popularization and application of the arc-shaped cable tunnel in the future.
