土牛拱胎在拱桥拱圈施工中的应用

Application of Earth-cattle Arch Vaulting in Arch Ring Construction of Arch Bridge

结合咸宁大洲湖环湖绿道某上承式拱桥梁施工,对采用土牛拱胎进行拱圈施工的方法进行了介绍。通过实践应用,证明利用土牛拱胎进行拱圈施工的工艺,极大地缩短了施工周期,确保了施工质量安全,并有效降低了工程成本,可为类似拱形桥涵施工提供参考。

Combine with the construction of a deck arch bridge on the greenway construction around the Dazhou Lake in Xianning,the construction method of arch ring using earth-cattle arch vaulting is introduced.The construction results verifies that the construction technology of arch ring using earth-cattle arch vaulting greatly shortens the construction period,ensures the construction quality and safety,and effectively reduces the project cost,which can provide a reference for similar arch bridge and culvert construction.
