BACKGROUND As an important infrastructure, bridges are related to the smooth functioning of society and economy. How to build bridges economically, safely and rapidly is an important issue that has long been studied by scholars and engineers. In recent years, with the popularization of fabricated construction technology in the field of bridges, cast-in-place members in bridge structures are gradually replaced by prefabricated members. The construction speed of the bridge has been significantly improved as the members are fabricated uniformly by local factories according to the standard formwork, and then transported by vehicles to the construction site for installation. In this process, the bridge foundation part needs to be manufactured and transported in sections due to its length and weight, and assembled at the construction site. Cranes are required to hoist tubular piles for installation and lowering during assembly, and large cranes are needed as the weight of the prefabricated tubular pile is large and often exceeds 100 t. However, in many cases, the construction site environment is complicated, and the construction site cannot meet the placement of such a large crane, the larger the crane, the greater the cost increases exponentially. Meanwhile, such a way cannot accurately adjust the spatial position of the tubular pile, and thus cannot meet the demands of the fabricated construction. To solve the problem above, make the installation and connection operation of the tubular piles more standardization and modularization, and reduce the unstable factors in the construction process, a fabricated rapid construction platform for a bridge and a construction method therefor are provided in accordance with the present disclosure. SUMMARY In view of the above, it is necessary to provide a fabricated rapid construction platform for a bridge and a control method therefor, so as to solve the problems that the traditional hoisting manners have excessively large local stress, use a large number of apparatuses for hoisting, consumes lone time for hoisting, and have difficulty in controlling accurate connection of joints during a pile connection process.
