我公司在金竹山电厂180米钢筋混凝土烟囱滑模施工中,针对中心飘移、平台扭转和垂直对中等几个问题采取了一些措施。仅用120天完成了烟囱施工任务,比国家规定工期提前了100天。而且质量优良,筒身中心最大偏差仅18毫米,为国家规定允许偏差的1/10。降低成本5.77%,节约金额40080元。一、工程概况烟囱下部筒身内径15.17米,筒首内径5米,下部壁厚42厘米,顶部壁厚16厘米。筒内+5米标高处设有一灰头平台,系现浇梁板结构。筒身分三段变坡,25米以下坡度为5%,25～
In the construction of the 180-meter reinforced concrete chimney slipform at Jinzhushan Power Plant, our company has taken some measures for center drift, platform twisting and vertical alignment. The chimney construction task was completed in only 120 days, 100 days ahead of the national schedule. And the quality is excellent. The maximum deviation in the center of the barrel is only 18mm, which is 1/10 of the allowable deviation of the national regulations. Reduce the cost of 5.77%, save a sum of 40080 yuan. I. Project Overview The inner diameter of the chimney in the lower part of the chimney is 15.17 meters, the inner diameter of the first tube is 5 meters, the lower wall thickness is 42 centimeters, and the top wall thickness is 16 centimeters. There is a grey head platform at the +5m elevation in the cylinder, which is a cast-in-situ slab structure. Three-stage change of slope of the cylinder, with a slope of 25 percent and 25 percent
