摘要
兰溪桥水库扩建工程主要是对原大坝进行加高,泄流建筑物控制段、冲砂洞洞身段进行改造,引水发电洞进出口段进行拆除重建,并新建输水隧洞。工程施工工期紧,工程规模大,防渗要求高,在施工期施工导流方案制定特别重要,关系着整个工期和工程安全。针对工程布置的特点,制定合理导流方式以及度汛计划,并进行上游围堰设计与施工、施工截留及封堵蓄水、基坑排水等方案设计,从而保障主体工程顺利、安全施工。
The expansion project of Lanxiqiao Reservoir includes raising the original dam,renovating the control section of the discharge building and the body section of the sand flushing tunnel,demolishing and rebuilding the inlet and outlet sections of the water diversion and power generation tunnel,and constructing a new water conveyance tunnel.The construction period is tight,the project scale is large,and the anti-seepage requirements are high.It is particularly important to develop a construction diversion plan during the construction period,which is related to the entire construction period and project safety.Based on the characteristics of the engineering layout,reasonable diversion methods and flood control plans are formulated,and upstream cofferdam design and construction,construction interception and sealing water storage,foundation pit drainage and other scheme designs are carried out to ensure the smooth and safe construction of the main project.
