近日,在贵阳小河区一鸣宽城国际施工现场,山河智能SWDM25A旋挖钻机顺利完成三根试桩成孔,成功实现2 m大桩径,钻孔深52.3 m(黏土层3 m、强风化岩层23 m、中风化岩层26.3 m、单轴抗压强度16～35 MPa)入岩,再创复杂地质成孔入岩新纪录。继兰新高铁后,山河智能旋挖钻再次向高难度工程挑战,并以高稳定性的综合表现和实力,获得使用单位高度认 Recently, at the Yitong Kuming International Construction Site in Yichang Xiaohe District, Guiyang, the SWDM25A Rotary Drilling Rig successfully completed three test pile forming holes and achieved a 2-m large pile diameter with a depth of 52.3 m (clay layer 3 m, strong weathered rock formation 23 m, aeolian rock 26.3 m, uniaxial compressive strength 16 ~ 35 MPa) into the rock, creating a new record of complex geological formations into the rock. Following the new high-speed rail, the Sunward intelligent rotary drilling once again challenge to difficult engineering, and high stability of the overall performance and strength to obtain high recognition of the use of units
