硬岩地层微型钢管桩抑尘降噪绿色施工技术研究OA

During the construction of miniature steel pipe pile in hard rock stratum,pneumatic DTH hammer is usually used as hole-forming equipment,which is easy to produce loud noise and dust,especially for subway construction in downtown areas,which is not conducive to safe and civilized construction.lead to complaints,letters and visits and other related negative effects.By installing a high-power vacuum cleaner at the orifice of the drilling rig to collect drilling slag,cuttings and dust,the dust concentration in the air can be effectively reduced and dust control can be realized;the sound barrier material is used to make sound insulation shed and a new type of air compressor with muffler device is used to control the n hole-forming process of miniature steel pipe pile is realized.
