较小直径的超深地下结构碳钢护筒高精度打设施工技术

High Precision Tamping Construction of Carbon Steel Sleeve with Smaller Diameter Adopted in Super-deep Underground Structure

上海国际旅游度假区某乐园城堡表演区声光塔地下结构需埋设不锈钢管,业主有着高精度的要求,同时也要求施工单位保证高精度打设地下结构的碳钢护筒。为完成此项建筑领域无先例可循的任务,经过不断探索、实践,采取了一系列的技术措施确保了碳钢护筒的高精度打设,为后续工程的顺利施工打下了坚实基础。

stainless pipe should be embedded in the underground structure of castle light tower in SHDR. Employer has high precision requirement and construction unit was required to tamp the underground carbon steel sleeve in high precision. To complete this historical task,CS8 continuously explored,practiced and took a series of technical measurement to ensure the carbon steel sleeved tamped in high precision,which lays solid foundation for the follow-up construction.
