超大异形断面调压井开挖及支护技术研究

Research on Excavation and Support Technology of Pressure Regulating Well with Extra-Large Irregular Section

结合具体工程实例,介绍了调压井的总平面布置,对调压井开挖及支护技术要点展开了详细的研究,并提出了调压井施工质量控制措施要点。通过对现场施工顺序、各不同施工部位爆破参数确认及起吊系统的研究,保证了施工进度,提高了现场施工质量,实现了施工期间安全生产零伤亡事故的目标。

Combined with specific engineering examples,his paper introduces the general layout ofthe pressure regulating well,carries out a detailed study on the key points of the excavation and support technology of the pressure regulating well,and puts forward the key points of the quality control measures forthe construction ofthe pressureregulating well.Through the study ofthe construction sequence,the confirmation of blasting parameters of different construction parts and the lifing system,the construction progress is guaranteed,the construction quality is improved,and the goal ofzero casualties in safe production during construction is realized.
