Large-section diversion tunnel excavation construction method
The invention relates to a large-section diversion tunnel excavation construction method, and relates to the technical field of hydraulic engineering construction. The method comprises the steps that upper-layer, middle-layer and lower-layer excavation supporting construction is set according to the section of a tunnel; excavating and supporting construction is conducted on the upper layer, excavating and supporting construction is conducted on the middle layer after the upper layer is excavated by a first distance, and excavating and supporting construction is conducted on the lower layer after the middle layer is excavated by a second distance; during excavation and support construction, drainage ditches are formed in the side edges of the upper layer, the middle layer and the lower layer. According to the scheme provided by the invention, the relatively independent working faces are formed through channel conversion, a multi-layer and multi-part excavation method is formed, and the middle-layer excavation support does not occupy a linear construction period, so that synchronous and same-direction construction of the multiple working faces is realized, and the project construction period can be effectively shortened.
本申请是关于大断面引水隧洞开挖施工的方法，涉及水利工程施工技术领域。该方法包括：根据隧洞断面，设置上层、中层和下层开挖支护施工；先对上层进行开挖支护施工，待上层开挖第一距离后，进行中层开挖支护施工，待中层开挖第二距离后，进行下层开挖支护施工；在进行开挖支护施工时，在上层、中层和下层的侧边设置排水沟。本申请提供的方案，通过通道转换形成相对独立的工作面，形成多层多部位的开挖方法，且中层开挖支护不占直线工期，因此实现了多工作面同期同向施工，能够有效缩短工程工期。
