在广蓄电站高压长斜井施工中,先采用正、反井同时掘进的方法开挖导井,后自上而下采用掌子面垂直于洞轴线方法扩大开挖,用XDM-8.5型多功能模板和引进的斜井滑模进行混凝土衬砌。在灌浆施工中,为防止发生水力劈裂,采取了“低压慢灌、逐步升压、控制灰量、浓浆待凝”的对策。通过充水试验,施工质量达到了要求。 In the construction of the high pressure long inclined shaft of Guangzhou Pumped Storage Power Station, the guide shaft was firstly excavated by simultaneous and anti-shaft simultaneous tunneling, and the excavation was extended from the top to the bottom perpendicular to the axis of the tunnel with XM-8.5 type Function template and the introduction of inclined shaft sliding mode for concrete lining. In the grouting construction, in order to prevent the occurrence of hydraulic fracturing, the countermeasures of “low pressure slow irrigation, gradual pressure increase, gray control, thick slurry to be coagulated” were taken. Through the water filling test, the construction quality has met the requirements.
