摘要
随着社会经济的不断发展和人们生活水平的提高,汽车成了人们生活、出行的主要交通工具。车辆的广泛使用方便了人们的生活,却给路桥建设项目增加了较大压力。本文结合某跨江大桥桩基加固施工经验,提出一种组合式单壁钢围堰和环向吊放装置,完善了基于单壁钢围堰地扩大截面桩基的加固施工工艺,提高了桥梁桩基加固质量和工期,有效解决了施工难度大、造价高、临时措施复杂等问题。
With the continuous development of social economy and the improvement of people's living standards,cars have become the main means of transportation for people's life and travel.The wide use of vehicles has facilitated people's life,but it has increased great pressure on road and bridge construction projects.In order to overcome the problems of construction difficulties,high cost and complex temporary measures,combined with the construction experience of pile foundation reinforcement of a river crossing bridge,this paper successfully developed the combined single wall steel cofferdam and circumferential lifting device,and explored the reinforcement construction technology of pile foundation with expanded section based on single wall steel cofferdam,which has effectively improved the reinforcement quality and construction period of bridge pile foundation.
