Round tunnel track bracing support and construction method
The invention relates to a round tunnel track bracing support and a construction method. The bracing support is made of joist steel and steel plates, and the bracing support is structurally composed of a joist steel transverse support, joist steel vertical supports and joist steel inclined supports. The joist steel vertical supports and the joist steel transverse support are symmetrically connected, and the joist steel inclined supports are connected between the joist steel transverse support and the joist steel vertical supports to form united supporting of the inclined supports and the vertical supports; and marshalling locomotives are placed on the joist steel transverse support, and reinforcing ribs are arranged at the positions, corresponding to the two joist steel vertical supports, of the joist steel transverse support. The manufactured bracing support is mounted at the position, located on the lower portion of a track of the marshalling locomotives, in a round tunnel, and is fixed, so that stability of a track system is ensured. By means of the bracing support, investment of prefabricated inverted arch concrete can be reduced, and the engineering cost can be saved; and the construction speed of track laying is high, and the construction efficiency is improved.
