Excavate for construction bypass and muck stockpiling platform within construction area, and form the temporary drainages in the excavation areas simultaneously. The earthwork excavation for the left abutment PHASE I excavation shall adopt backhoe or loader cooperating with 15t HONGYAN tippers for excavation and loading, with spoil materials transported to NO.1 or 2 muck disposable site. The slope of the earthwork shall be excavated by backhoe and trimmed manually. 2. 土石方开挖工艺流程及措施分层分区进行钻孔、爆破、出碴及支护施工，形成开挖多工作面多工序的平行流水作业。边坡及强风化岩石采用反铲从上往下开挖，开挖碴料顺坡面翻碴到下一马道，再用反铲或装载机装自卸汽车拉运至1弃碴场。开挖揭露的石方进行孤石解爆，人工YT28手风钻钻孔，松动爆破，碴料弃至指定碴场。2. Earthwork and stonework excavation process and measuresExecute the drilling, blasting, mucking and retaining support construction hierarchically and in partitions, forming parallel excavation constructions of multiple working sections and multiple processes. Use the backhoe for strongly weathered rock and slope excavation from top to bottom, and the excavated muck materials shall be turned to the next pack-way through the slope surface, and then loaded to the tipper by backhoe or loader for transportation to No.1 muck disposable site. The exposed stone shall adopt boulder blasting method with manual YT28 hand pneumatic driller by shock blasting （loosening blasting）, and the muck materials of which shall be spoiled to appointed muck disposable site.
