Research on Erection Technology of Precast Prestressed Concrete Beam of Highway Bridge
In highway bridge engineering,concrete beams are prone to cracks,rebar exposure,surface defects and other diseases,which affect the construction quality and the traffic safety of highway bridges.How to improve the construction quality of concrete beams of highway bridges has become a key problem to be solved urgently.Prestress technology has the advantages of improving the strength of components,reducing vibration and elastic deformation,which is conducive to reducing the incidence of quality diseases of concrete beams.Based on this,this paper stud-ies the erection technology of precast prestressed concrete beams of highway bridges,aiming at improving the sta-bility and reliability of highway bridge engineering and ensuring the safety of passing vehicles after the highway bridge is delivered for use.
