防尘天幕系统在深基坑施工中的应用

APPLICATION OF DUST-PROOF SKY CURTAIN SYSTEM IN DEEP FOUNDATION PIT CONSTRUCTION

为治理深基坑土护降阶段中的扬尘,以中电建某项目施工中的22.8m深基坑为例,通过研发一种由钢板桩基础、槽钢轨道、多单元电动开启的防尘天幕系统。该项目中的基坑长约200m、宽约100m,其扬尘治理效果明显,同时还起到了隔声降噪、遮阳的效果,最终实现了预期目标,满足了其绿色施工的要求。

To control dust during the soil protection and lowering stage of deep foundation pits,taking a 22.8 m deep foundation pit in a construction project of China Electric Power Construction Corporation as an example,a dust proof canopy system consisting of steel sheet pile foundation,channel steel track,and multi unit electric opening was developed.The foundation pit in this project is about 200 m long and 100 m wide,and its dust control effect is obvious.At the same time,it also plays a role in sound insulation,noise reduction,and shading,ultimately achieving the expected goals and meeting the requirements of green construction.
