一、编制说明Intro
本格栅板安装方案是针对Team D格栅板施工的特点，以道康宁（张家港）有限公司19万吨/年有机硅聚硅氧烷项目（二期）工程施工图纸、美罗格栅板公司的格栅板详图、国标、江苏省地方标准及道康宁张家港有限公司相关程序文件和东洋公司、上海协同监理公司相
关管理规定为编制的依据。

本方案仅实用于Team D钢结构工程格栅项目的安装工作，作为指导生产确保安全作业的依据。

This Grating Installation Method Statement is based on characteristics of T eam D grating work; it is compiled according to construction drawings of Dow Corning 190kt/a Siloxane Project in Zhangjiagang (Phase 2), detail drawing of grating from Webforge Grating Co., Ltd,GB code and Jiangsu Specifications, Regulations of TOYO and TJU.

二、工程概况General Info
Team D钢结构安装工程是道康宁（张家港）有限公司19万吨/年聚硅氧烷项目（二期）工程的一部分，共24条管架结构，分布于整个二期施工区域，格栅板主要用于管架上人行通道及设备作平台的铺设。

本工程采用的格栅以品牌为无锡美图罗，其型号为W A255/1G，表面处理方式为热浸锌处理。

Team D Steel Structure installation work is part of Dow Corning 190kt/a Siloxane Project in Zhangjiagang (Phase 2). The main structure consists of 24 pipe racks which mainly serve as walkway and operation platform. WA255/1G Grating supplied by Wuxi Webforge Grating Co., Ltd will be paved at equipment operating platforms and stair platforms. Hot-dip galvanizing treatment will be performed on the surface of gratings.
由于本工程结构层次较多，梁、脚手架、缆风绳等纵横交错，对格栅板的安装工作带来了诸多不便，再加上管架遍布整个二期厂区，安装工程又在结构安装的后期，基本上整个厂区格栅板同时布置，战线较长。

The structure of platforms is complicated with crisscrossing beams, scaffolds and mooring ropes, which bring inconvenience for grating installation work. Pipe racks are distributed all over
Phase 2. Grating installation will be performed at the ending period of structure installation work. Grating
installation will be executed at a large area of the site.
三、人员、机具配备Mobilization of Manpower and Machinery
3．1机具配备Mobilization of Machinery
原则上，格栅板的吊装每条管架配备一台25吨汽车吊，亦可根据现场实际情况灵活调整吊机配备，如21a、R28、R29管架可共用一台25吨汽车吊。

Each PR will have a 25T truck crane in principle. Crane could be mobilized according to site situation. 21a、R28、R29 could share a 25T truck crane.
3．2人员配备Mobilization of Manpower
根据现场情况，每台吊机配驾驶员1名，起重指挥1名，安装工5名，共计7人，吊装完成后格栅板安装人员的配备根据管架的长管及格栅板的工作量灵活配备。

According to site condition, each crane will have one crane operator, one crane rigger, five erectors. So each team has seven workmen. Manpower for grating installation work will be mobilized as per length of PR and workload of gratings.
四、施工方案Construction Plan
