External slanted type steel box arch installing method
The invention discloses an external slanted type steel box arch installing method, which belongs to the technical field of the bridge construction. The external slanted type steel box arch installing method includes the following steps: an arch rib and an arch section are operated to complete turning to the side and turning over on the ground; after the arch section is lifted on a bracket at the top of a support, the fine adjustment of the accurate positioning of the arch section is performed through a trim holder arranged at the top of the support, a support top bracket and a jack; after the position of the arch section is adjusted in place, the temporary welding positioning measure is performed, and the arch section positioning and installing are completed. The optimized less support method according to the invention has the advantages that the posture adjusting process is performed on the ground, meanwhile, the arch section is accurately positioned though the trim holder, the support top bracket and the jack, the high altitude construction safety risk is eliminated, the quality control risk is lowered, the construction operation is convenient, the construction speed is fast, and the construction period can be saved about 30 days compared with the traditional less support method.
