Construction Technology of Drilled Cast-in-place Pile for Longhu Interchange of Longcheng Expressway
With the rapid development of highway bridge construction,bored pile as one of the important forms of pile foundation,its construction technology is particularly important.In order to ensure the stability of the road and bridge foundation,improve the load bearing capacity of the road and bridge structure,and enhance the overall safety of the infrastructure,the construction technology of the bored pile of the road and bridge is studied.Choosing the suitable type of bored pile,calculating the bearing capacity of pile foundation according to the construction condition,using the post-grouting technology of bored pile to increase the resistance of pile foundation and the ultimate bearing capacity of pile foundation,then the stability of road and bridge foundation can be enhanced.It is proved that the bearing capacity and stability of bored pile are better by using the grouting technique.
