Research on Construction Technology of Double-motor Sleeve Auger Drilling Press-Grouting Secant Pile
Based on Baili Qiantang comprehensive improvement and upgrading engineering in Haining City of 100 billion shore Anlan engineering in Zhejiang Province,this paper developed a construction method of double-motor sleeve auger drilling press-grouting secant pile with high efficiency,environmental friendliness and convenient operation.The process principle was analyzed,and the construction process and operation points were studied,including measurement lofting,guide wall construction and drilling rig positioning.The engineering practice shows that the method has the advantages of large drilling diameter,small vertical deviation,fast drilling speed and no squeezing soil force,and the social and economic benefits are remarkable.
