Abstract

The invention discloses a 100t cross-pier gantry crane assembly type segmental beam assembly construction method which is used for a municipal rapid engineering viaduct, according to the method, two 100t cross-pier gantry cranes are adopted for symmetrical cantilever assembly construction in prefabricated segmental beam assembly, operation is convenient, safety and reliability are achieved, the construction progress is high, the gantry cranes serve as beam erecting equipment, and the construction efficiency is high. Meanwhile, the device can also be used as middle transfer equipment for unloading and storing beams, and the universality of the device is well played in narrow sites of municipal bridge construction; and the use cost of beam unloading and storing mechanical equipment is reduced, and the construction period of staged beam erection is shortened.

Description

technical field [0001] The invention belongs to the field of bridge construction, and in particular relates to a 100t pier-span gantry crane assembled segmental beam assembly construction method. Background technique [0002] In 1990, bridges in our country first adopted segmental prefabricated assembly construction. The segmental assembly construction technology was also gradually applied in highways, railways, and municipal engineering. What does not match the development trend is that there are few researches on segmental cantilevered bridges in my country, and the corresponding standards for segmental prefabricated bridges in the code are not comprehensive. At the same time, due to the lag in research and development of large-scale equipment required for segmental prefabrication and assembly construction, the development of construction technology is slow, and the matching prefabrication technology and the linear control accuracy of bridge assembly need to be improved, w...
