Example Embodiment
[0027] The present invention will be described in detail below in conjunction with specific embodiments.
[0028] The invention relates to a prefabricated and erected simple-supported beam prefabricated channel steel widening treatment structure between tunnels, which can be prefabricated in a beam yard and pre-assembled and sleeved. After splitting, the beam transporter or transport and erection integrated machine is used to transport and directly erect the sleeve. Connect and pour the post-cast-in-place vertical wall, etc. It can greatly simplify the on-site construction process and effectively shorten the construction period, which has obvious economic benefits.
[0029] The present invention makes the prefabricated box girder 1 transition from the original standard beam width of 12.6m to the prefabricated box girder beam width of 12.1m. The prefabricated channel steel member 2 is arranged outside the flange end surface of the prefabricated box beam 1, and the prefabricated chan...
