摘要
通过施工方案的比选,确定在昆明枢纽扩能改造工程中采用高压旋喷桩帷幕施工方案,具体阐述了其施工工艺和安全质量保证措施,实践证明,采用该方案克服了钻孔、注浆困难的情况,解决了流砂层地层桩基难以成孔的难题,节约了成本。
Based on construction scheme comparison,the high-pressure jet grouting curtain pile foundation holing construction scheme is determined to apply in Kunming hub energy-expansion transformation engineering. The paper specifically describes its construction technology and security quality guarantee measures. Practice proves that： the scheme solves drilling and grouting difficulties,solves quicksand stratum pile holing problem,and saves cost as well.
