摘　　要：为响应国家绿色节能号召,贯彻国家绿色建筑施工理念,菜园街及枣林南里棚户区改造项目A地块采用在土方开挖阶段引入防尘天幕系统,采用钢结构预埋件与基坑支护冠梁固定牢固,使用钢结构焊接成防尘天幕骨架,通过电动滑轮组件牵引钢丝绳,实现网布单元从南向北侧开合。天幕开启后达到全封闭施工效果,从而实现基坑土方作业阶段无扬尘、有效降低光污染、噪声污染。In order to respond to the national call for green energy conservation,implement the national concept of green building construction,build high-quality projects,resolutely win the blue sky defense war,and from the overall situation of environmental protection,Plot A of Caiyuan Street and Zaolin Nanli shantytown renovation project adopts the introduction of dust-proof sky curtain system during the earthwork excavation stage,and adopts steel structure embedded parts and foundation pit supporting crown beams to fix firmly.Then the steel structure is welded into the dust proof ceiling skeleton,and the wire rope is drawn by the electric pulley assembly to realize the opening and closing of the mesh cloth unit from the south to the north.After the sky curtain is opened,the construction effect is completely closed,so as to realize no dust in the earthwork stage of the foundation pit and effectively reduce light pollution and noise pollution.
