| Abstract: | Because excavation pile construction is simple and easy,the low demand for construction field,construction speed fast,and with little noisy and small input on equipment,excavation pile construction has become a priority construction method in the design of bridge pile foundations in mountain area and city.Taking the cross railway section excavation pile foundation construction in Qingdao east-west expressway(3rd period) as an example,this paper describes the application of large diameter concreter slurry-supported excavation pile construction in municipal construction. |
