调压井所在区域地质条件较差,岩石以片状碳质页岩为主,节理发育,风化严重。施工风险因素较多,对施工技术水平要求较高。以调压井施工为例,介绍了开挖支护施工方法、质量保证措施、安全文明施工及环保控制措施。 The region where the surge tank is located has poor geological conditions. The rock is mainly composed of flaky carbonaceous shale, and the joints developed and weathered severely. More construction risk factors, higher requirements on the construction technology. Taking the surge shaft construction as an example, the construction methods, quality assurance measures, safe and civilized construction and environmental protection control measures for excavation and support are introduced.
