江垭水电站引水发电系统金属结构主要包括进水口闸门及启闭机械、引水压力钢管、尾调室和尾水隧洞出口闸门及启闭机械等 4大部分 ,安装工期历时 3a,1 998年 1 2月金属结构全部安装完毕。面临安装期间历经2个洪水期防汛挡水 ,施工交错作业 ,技术难度大等困难 ,监理工程师以合同文件、设计图纸技术文件及有关验收规范为技术标准进行监理 ,采取“三控制 ,二管理 ,一协调”的监理办法 ,坚持“质量第一” ,完善和健全质量保证体系 ,以监测数据为依据 ,建立和完善各种检测表格 ,使其规范化、系统化。工程建设监理工作既满足了工程进度 ,又保证了设备制造和安装质量。 1 999～ 2 0 0 0年进出口闸门及启闭机械投入运行。运行情况正常 ,满足了机组发电和防洪要求。金属结构安装质量合格率 1 0 0 % ,优良率 74% ,安装质量达到优良等级
The metal structure of the Jiangya Hydropower Station diversion power generation system mainly consists of 4 main parts: inlet gate and opening and closing machinery, pilot pressure steel pipe, tail gate and tailrace tunnel exit gate and opening and closing machinery, etc. The installation period lasted for 3 years and 1 in 1998 All month metal structure is installed. Faced with such difficulties as flood control and water blocking in two flood periods during the installation period, staggered construction work and technical difficulties, supervisory engineers supervised technical documents with contract documents, design drawings and relevant acceptance specifications as technical standards, and adopted “three control, two management, A coordinated ”approach to supervision, adhere to the“ quality first ”, improve and perfect the quality assurance system to monitor the data as the basis for the establishment and improvement of a variety of test forms, to standardize and systematize. Construction supervision work not only to meet the progress of the project, but also to ensure the quality of equipment manufacturing and installation. 1 999 ~ 2000 import and export of gates and hoist machinery put into operation. The operation is normal, to meet the unit generating and flood control requirements. Metal structure installation quality pass rate of 100%, excellent rate of 74%, the installation quality to achieve good grades
