Shanghai Daoqin Plastics Co., Ltd.

        经 三 month 艰苦努 force, to 10 month 24 day, chemical industry group Tenth Construction 承建 烟台万华 ethylene plant/unit most high equipment propylene 精馏塔 inner parts 安装按预定工期提 front 30天完 formed, 并创造 also 一亮点 and more “之 most ”, 业主领导 for Tenth Construction 施工人员不畏艰 difficult, as 战, can in relatively short time formed this high difficult degree as to high degree 赞赏.

         propylene 精馏塔 most high, most heavy, difficult degree most large, 筒体直径8.5米, high 114.3米, equipment weight 1460吨, 于2019 year 2 month 24 day formed “穿衣戴帽” one-time overall 吊装就位. its in inner parts 共计215层, especially it large, 安装程序 complex, by is 吊装完 formed rear 堡垒工序.

         inner parts is sheet/plate and drop liquid combined, 无支承梁 structure. remove and welding 塔盘支撑圈 and internal 支架, internal full 空, internal structure to 现场施工 belt/tape large 挑战. sheet/plate 安装, if need 按图进行拼组, versus for simple 一点, is, sheet/plate semi inner 就设置一处螺栓, 一层塔盘安装完 need solid 约一千 sleeve/set 螺栓, sleeve/set 螺栓都 need according to requirements methods 安装, in high 空并受限空间 add high temperature gas lower as 业, can 谓举步维艰.

        114 more high propylene 精馏塔每天 use 直爬梯 upper lower is 施工人员 必修课, small 宋以7 separation 46秒爬 upper 94米平台 记录无人 can 破. is decrease/reduce upper lower 次数积蓄精 force, upper upper 塔一呆就 is 一天, 午饭随吊车送 to as 业面, 每 人自 belt/tape 尿桶.

         propylene 精馏塔 安装 塔盘 is USA Honeywell product, not only manufacturing precision, quality requirements more add 严格. as 业时必 must 先进行 remove 锈, upper “三 anti ”布, use magnetic iron to upper, rear again use large rate device 进行清理;塔盘支撑圈 water degree small 于5 mm, inner 塔盘支撑圈 usually is 7 to 10 mm;塔盘验收 has 9项, 每一项都犹如鸡蛋里挑骨头, fine also fine, 塔盘验收完 also need 拍摄3 separation 钟塔盘 and 12道 drop liquid 槽 视 frequency, and 4 方位角, 螺栓, device sheet/slice as is 足够 备存资 material.

        施工办 method most more, is ensure 工期, quality, safety can meet/satisfy requirements, Tenth Construction 烟台万华 project through and 业主, 厂家, 监理沟通, in equipment internal 依托10 人孔, through 脚手架做 4 工 as and 4 进 material 平台, and use 工字钢借助塔盘支撑圈 made as 4处吊装点; its is ensure as safety and 清洁, using/adopting 满铺跳 sheet/plate rear again cover/cap anti methods hard anti 护隔离, meanwhile 安装 4台轴流风 machine ensure inner as 业通风良 good. as 业人员 in 入口设置 鞋 sleeve/set, filament 刷, anti 止进塔人员 for internal generate 二次污染, use foam soft viscous for method 兰入口进行保护.

         if for high degree conditions selection 吊车, 一层层往 upper 安装, 导致吊车配 combined time and 塔盘安装 time 交错不连续, will 导致吊车消 consumption large, long, cost large, efficiency low. for 此, 施工人员 through and inner parts 厂家, 业主, 监理交流沟通, in inner through more 次搭设脚手架, more 隔断层 and material 平台, achieve more as meanwhile as 业. separation utilizing 现场空间, adjustment 周边配 tube/pipe 施工, achieve 2台吊车 meanwhile 进行塔 inner parts as 业. through upper lower more meanwhile as 业, achieve large degree improve/increase efficiency.

         heavy degree most high, Tenth Construction project for solution/scheme made, as 业人员遴选, 整 组织 process 都进行 事先策划. di how to lower this block hard 骨头工 as for 接时, project according to experience 曾预言至 less 8 to 10 month 工期, 而我方承诺4 month formed, to 业主方许诺 惊喜 期待. 施工开始于八 month 初, month to high 峰, this 期间 烟台天 gas hot 浪袭人, inner temperature degree more add hot, as 业人员进入塔 inner 5 separation large 汗淋漓. its 间, project 部领导 in 各专业工序交叉, 现场错综 complex, comprehensive 开花 形势 lower, especially is inner parts 安装开 good 绿灯, has issues time 现场就 solution.

        安装 speed degree most fast, add add is 家常便饭, 参建团队没 has by 任何困 difficult 吓倒反而越挫越勇, degree 越 也 fast, from most 初 3天安装1层, add fast to 两天3层, 一天2层, most 终展开 8 as 业面, to 一天8层. 验收工 as 也紧锣密鼓, from most 初 3天1层 to 一天1层, 一天2层, 3层, 4层, 直至1天验收6层, quality safety 受控, degree overall 推进. rear, 业主方 主 tube/pipe again degree Tenth Construction tool has difficult front especially can 战斗, especially has method, key/critical can 打胜仗 tough 劲, through enterprise 宣传部门 as 专题报道, is 参建施工队申报“建功班组”荣誉称号.
