Preferably, the two support devices are symmetrically arranged with the center of the pushing device as the center.

[0029] The support device comprises a main support mechanism 7 arranged vertically, which comprises a jack or a hydraulic cylinder arranged vertically, for example, and the extending rod of the main support mechanism is arranged upward. In an alternative embodiment, the upper end of the extending rod of the main support mechanism is provided with a contact plate 15, which abuts against the bottom of the steel truss when the extending rod of the main support mechanism is extended upward, so as to increase the contact area between the main support mechanism and the steel truss, and the support device can stably support the steel truss.

[0030] The auxiliary support device comprises an auxiliary support mechanism 8 arranged vertically, and the pushing device comprises a base 9, on which a pushing mechanism 10 is installed, and the pushing mechanism comprises a coupling seat 11 driven by a horizontal pushing mechanism 12 installed on the base.
