Installation and Construction Technology of T-beam for 85 m Small Curve Radius Ramp Bridge
The second bridge of D-ramp in the fourth contract section of Zhitong Expressway is a small radius curved ramp bridge.This article introduces the implementation of beam feeding and crossing in the installation of T-beams for the small radius curved ramp bridge.By reasonably selecting bridge erecting equipment and optimizing and adjusting the construction process of T-beam erecting,the safety of the bridge erecting machine crossing the span on the 85 m small curved half diameter and feeding the beam on the 10m bridge deck width can be ensured,Provide reference significance for the installation of T-beams on small curve radius ramp bridges in the same type of construction environment for mountainous highways.
