Abstract

The invention discloses a light rail elevated prefabricated box girder erection construction device and a construction method thereof. A zero column is fixed to a front pier column support cushion through a zero column adjustment section, and the top end of the zero column is provided with a zero column rotating seat. A first column transverse moving rail is arranged on the position, adjacent to the zero column adjustment section, of the front pier column support cushion, and a first column is erected on the first column transverse moving rail through a first column transverse moving mechanism. A second column transverse moving rail is arranged at the front end of an erected prefabricated box girder, and a second column is erected on the second column transverse moving rail through a second column transverse moving mechanism. A third column is erected in the middle of the erected prefabricated box girder through a third column hydraulic system. The zero column and the first column aresupported at the front end of a device arm, the second column is supported in the middle of the device arm, and the third column is supported at the tail end of the device arm. A front hanging beam trolley and a rear hanging beam trolley are connected with the device arm in a hanging mode. The construction requirement can be met only by correspondingly easily adjusting the bridging construction method, under the premise that construction safety is guaranteed, the construction schedule is accelerated, and the construction cost is reduced.

Description

technical field [0001] The invention relates to a light rail elevated prefabricated box girder erection device and a construction method thereof, belonging to the technical field of building construction. Background technique [0002] With the continuous development of my country's urbanization process, the traffic pressure in large and medium-sized cities is increasing. In order to alleviate the pressure of the rapid growth of ground traffic in large and medium-sized cities, the construction of urban rail transit is developing rapidly. Light rail elevated prefabricated box girders are more and more used in rail transit viaducts because of their unique advantages. In the case of increasingly tight urban land resources, the light rail elevated often chooses a smaller curve radius to reduce the land use. At the same time, it is affected by obstacles such as underground pipelines, roads and buildings under the bridge, and measures such as single pier, single and double lines a...
