Steel truss arch bridge installation system and construction method thereof

Abstract

The invention relates to a steel truss arch bridge installation system. The steel truss arch bridge installation system involves a steel truss assembling and splicing base frame, a steel truss in-water installing support, a steel truss installing attaching type construction platform and a steel truss arch bridge pick arm hanging frame construction platform; the steel truss assembling and splicing base frame comprises connecting grooves, connecting steel sheets, base frame steel plates, base frame supporting legs and supporting leg lifting adjusting devices; the steel truss in-water installing support comprises top adjusting devices, steel pipe connecting devices and steel pipe piles; the steel truss installing attaching type construction platform comprises hanging baskets, upper rolling wheels, lower rolling wheels, upper face plates, lower face plates and steel beam splicing plates; and the steel truss arch bridge pick arm hanging frame construction platform comprises hanging frame rails, universal rolling wheels, pick arms, bottom plates and rail clamping devices. The steel truss arch bridge installation system has the beneficial effects that the arranged steel truss assembling and splicing base frame can solve the problem that a pre-assembling site is not flat, a base is stable and does not slip, and the base frame with the corresponding size can be quickly assembled according to the size of a pre-assembled unit so that steel truss components can be rapidly trial-assembled.

Description

technical field [0001] The invention relates to a steel truss arch bridge, in particular to a steel truss arch bridge installation system and a construction method thereof. Background technique [0002] With the rapid development of my country's urban construction and the improvement of bridge construction technology, steel trusses are more and more widely used in bridge construction. Most of the components of the steel truss arch bridge are prefabricated and installed. The construction involves the pre-assembly and hoisting of many bridge components. When building the main body of the steel structure, it is usually fixed by welding, bolts or rivets. During the connection and installation process, construction personnel need to carry out high-altitude operations at the connection. The formwork and support platform of the traditional installation system are complex, which usually brings a lot of inconvenience to the construction personnel's operation, and it is difficult to i...

AI Technical Summary

Problems solved by technology

During the connection and installation process, the construction personnel need to carry out high-altitude operations at the connection. The formwork and support platform of the traditional installation system are relatively complicated, which usually brings a lot of inconvenience to the construction personnel's operation, and it is difficult to improve work efficiency.
