Prepressing construction device of cantilever box beam No.0 block and prepressing construction method thereof
The invention discloses a prepressing construction device of a cantilever box beam No.0 block and a prepressing construction method thereof. The device comprises a bearing platform and a pier body arranged on the bearing platform, and a longitudinal beam is arranged on the pier body; four main supporting pipes are arranged on the bearing platform, the main supporting pipes are arranged at the two sides of the pier body, and two main supporting pipes are arranged at each side; each main supporting pipe is provided with the No.0 block; each No.0 block is connected with the longitudinal beam for supporting the longitudinal beam; the two ends of the longitudinal beam are each provided with a distribution beam, a strut-beam, a jack and a back pressing beam in sequence from bottom to top; the device further comprises deformed steel bars which pass through the back pressing beams, the jacks, the strut-beams, the distribution beams and the longitudinal beams in sequence correspondingly; the top of each deformed steel bar is fixedly connected to the corresponding back pressing beam through double nuts. According to the device and method, a support is subjected to leveled simulated pressing by utilizing the jacks, so that various technical parameters of block support deformation are obtained, the non-elastic deformation of the support is eliminated, and the method is simple, good in effect and suitable for being applied and popularized widely.
