一、编制依据Reference
1．1编制说明Intro
本施工方案针对Team D管架钢结构工程编制，我司承担的Team D管架工程分为24段管架，总长近1.3公里，钢结构总量近3800吨；管架宽度分别为2m、3m/3.5m、4m、6m、7m和8m，管架高度最高为22.1米。鉴于结构型式简单，施工方法相近，仅是在吊机选型上有所不同，为此我们将其中最具代表性的21a管架作为典型，来编制此施工方案，其它管架（R20a、R20b、R20c、R20d、R20e、21a、R22a、R22b、R22c、R23、R24a、R24b、R25a、R25b、R25c、R26、R33a、R33b、R33c、R34、R36）的施工参照此方案。
This construction plan is compiled as per actual site situation of pipe rack in Team D and is only applicable for installation of steel structure pipe racks. Since the project consists of 24 pipe racks which is 1.3 KM long and 3800 tons. Width of pipe racks are 2m、3m/3.5m、4m、6m、7m and 8m, highest part of pipe rack is 22.1 meter high. Structure type is simple and the installation method is the same with other areas. Here we will take the most difficult pipe rack, 21a, as an example to compile construction method. Other pipe racks (R20a、R20b、R20c、R20d、R20e、21a、R22a、R22b、R22c、R23、R24a、R24b、R25a、R25b、R25c、R26、R33a、R33b、R33c、R34、R36)share the same method.

二、工程概况General Info
21a全长94.8米(轴线到轴线)，宽度7米(轴线到轴线)，高度20米，最大跨距15米，最小跨距3.8米，共11条轴线，总重量约600吨。东侧与一期老管架相连，西侧与中核二三承建的管架相连，北侧为中建二局在建项目，南侧为张家港路，道路条件良好。但施工区域内拼装作业面狭小，且紧挨21a管架南侧有水沟在施工中，对拼装吊装、吊机站位带来了诸多的不便。
