The invention discloses a full-prefabricated assembly type bridge integrated installation technology. The technology comprises the following steps that 1, prefabricated parts are hoisted and transported; the construction method comprises the following steps of 1, installation of a prefabricated advanced pier, 2, installation of an advanced pier column, 3, installation of a main span small box girder, 4, installation of a prefabricated advanced pier cover beam, 5, span crossing of a bridge girder erection machine and 6, safety monitoring. The overall construction sequence of the process comprises the following steps: mounting an advanced pier column, mounting a main-span small box girder, mounting an advanced pier cover beam, crossing a bridge girder erection machine, and carrying out the next construction cycle. According to the integrated bridge girder erection machine, overturning, rotating and hoisting of prefabricated parts are achieved through the integrated bridge girder erection machine, the functions of half-range transportation and full-range erection of a bridge deck are achieved through the front supporting leg ground rail of the integrated bridge girder erection machine, and safe and reliable operation of installation operation is ensured through a real-time monitoring system. Therefore, environmental protection, quality, safety and efficiency of construction operation of a construction unit are greatly improved, the construction progress is accelerated, and related workloads are relieved.
