1.工程概况 湘潭电厂2×300MW机组工程,是国家“九五”重点工程之一,主厂房工程是电厂工程的“心脏”工程,由湖南省第五工程公司负责施工。该工程被列为98年度湖南省建筑业新技术示范工程,并于1999年9月21日通过湖南省“建筑业新技术应用示范工程”的验收,结论为“该工程推广应用新技术的整体水平达到国内领先水平”。 湘潭电厂2×300MW机组工程位于湘潭市近郊,距湘潭市区约15km。主厂房工程由汽机房、除氧煤仓间、单元集控楼、汽轮发电机基座及大中小型设备基础、工业管沟、电缆隧道、附属建筑工程等组成,建筑面积约3.9万m~2。工程主体为现浇钢筋混凝土框排架结构,楼板、屋面为钢与混凝土组合梁板结构,局部屋面采用钢屋架、钢支撑、大型屋面板结构体系,混凝土总量8万余m~3,钢结构制安总量3000t。该工程工程量大,工期紧迫,施工难度高,所以必须
1. Project Overview The Xiangtan Power Plant 2×300MW unit project is one of the national “Ninth Five-Year Plan” key projects. The main plant project is the “heart” project of the power plant project. The fifth engineering company in Hunan Province is responsible for the construction. The project was listed as a new technology demonstration project for the construction industry in Hunan Province in 1998 and passed the acceptance of the “New Technology Application and Demonstration Project for the Construction Industry” in Hunan Province on September 21, 1999. The conclusion was: “This project promotes the application of new technologies as a whole. The level reached the domestic leading level." Xiangtan Power Plant 2 × 300MW unit project is located in the suburbs of Xiangtan City, about 15km away from Xiangtan City. The main plant project consists of a steam turbine room, an oxygen-scavenging coal bunker room, a unit centralized control building, a turbine generator base, a large, medium, and small equipment foundation, an industrial pipe ditch, a cable tunnel, and an auxiliary building project. The construction area is approximately 39,000 m. ~2. The main body of the project is a cast-in-place reinforced concrete frame bent structure. The floor and roof are steel and concrete composite beam and plate structure. The local roof is made of steel roof frame, steel support, and large roof plate structural system. The total amount of concrete is more than 80,000 m3. The total safety of the steel structure is 3000t. The project has a large amount of work, the schedule is urgent, and the construction is difficult. Therefore, it must be
