Application of Drilling with Full Casing (Benote Method) in Cobble-Boulder Stratum in Xi’an-Chengdu High-Speed Rail
Abstract:The bridge pile is bored grouting one for Qingjianghe super large bridge of Xi’an-Chengdu high-speed rail; borehole drilling was difficult because of the cobble-boulder stratum crossing which seriously restricted the time limit for the project. In view of this circumstance, drilling with full casing and rotary drilling rig with casing oscillator were adopted to solve the difficulties of pile construction in cobble-boulder stratum.
