5、气),二、三期建设规模分别为公称能力400万Nm3/d(天然气)。本项目主要工艺单元装置包括:煤气化装置、空分装置、低温甲醇洗装置、甲烷化装置以及硫回收装置等,我单位此次承建的为空分界区内的建筑安装工程(一期)。工程设计单位为中国五环工程有限公司,监理单位为北京金海湾工程建设监理公司。大唐阜新煤制天然气项目空分装置设备基础施工方案第37页共37页中国化学工程第三建设有限公司空分装置设备基础主要含两个冷箱基础和若干个单体的设备基础,本方案主要编制内容为空分装置之中的冷箱基础分部工程。冷箱基础底板结构尺寸为14m*26m(长*宽,局部长度22m)、结构高度3米,一次性混凝土浇筑高度2.61m(局部
6、吊模区域浇筑高度2.95m),共两套冷箱基础。基础垫层以下处理采用膨胀土防水毯,垫层混凝土采用C10,基础混凝土采用C35防水抗冻混凝土(防水等级P12、抗冻等级F200)。冷箱基础在使用过程中将承受低温-190°且承受着很大的荷载,基础质量的好坏将直接影响到冷箱安全与制氧能力。由于业主对冷箱基础施工的工期要求较紧,如何改进施工方法使在确保质量的前提下加快施工进度,是冷箱基础施工的核心内容,因此特编制此方案。1.2主要工程量(概算量)名称数量名称数量土方(m3)1300*2砼C10(m3)45*2钢筋(t)120*2砼C35(m3)1200*2膨胀土防水毯(㎡)600*2模板(㎡)610*21
