13、至低一层一层往下开挖,每层开挖深度控制在3-4m为最佳。沿路线方向开便道,便道纵坡应保证自卸汽车空车在正常情况下能顺利爬到坡顶,同时因地制宜考虑错车处。4.1.2 陡峭地形施工若开挖地段沿线方向相对地形太陡,便道无法成型,则利用挖机开挖。本合同段YK136+180+250段地形陡峭则采用挖机开挖,因临河边滩涂,直接用挖机抛甩碴料至边坡底,再在坡底用出碴车将碴料运走。4.2 石方开挖路堑石方开挖采用松动控制爆破和光面爆破相结合的方案进行施工:半填半挖路段先挖浅地段,再挖深地段;风化层和松软岩部位,先用大马力推土机松动,对于无法松动的部分,实施松动爆破;风化层和松软岩地段的边坡用人工配合挖掘机清刷

14、,岩石地段用预留光爆层实施光面爆破;石方装车用挖掘机或装载机,运输用载重自卸汽车。 4.2.1 路堑石方开挖施工措施4.2.1.1 施工前,将爆破器材的存放地点、数量、警卫、收发、安全措施及施工方案编制报告,并在爆破器进入工地28天前报监理工程师审批,同时将运入路线和时间报有关部门批准。4.2.1.2 爆破作业人员必须经指定的部门培训,考试合格后持证上岗。4.2.1.3 在确定的爆破危险区边界设置明显的标志,建立警戒线、警戒信号,在危险区入口或附近道路设置标志并派专人看守,防止人、畜、公路设施等受到危害和损失。4.2.1.4 对靠近构筑物处的石方爆破要采取松动爆破,同时采取安全防护措施。采用炮

15、被对炮眼进行覆盖防护,炮被用废旧的轮胎剪成条状,编织后用铁丝绑扎。炮被覆盖的方法是:在起爆山体的炮眼表面覆盖炮被,每块炮被四角用粗铁丝拽拉固定在稳定的物体上,防止飞石。4.2.1.5 爆破检查:爆破之后,暂不要解除警戒,要到现场查看,发现哑炮应及时处理。4.2.1.6 对比较松软的岩石采用推土机、挖掘机松动开挖,对比较坚硬的岩石采用钻爆法施工。4.2.1.7 为减小爆破对边坡的振动破坏,控制爆破大块率,路堑石方爆破主要采用硝铵炸药及乳化防水炸药,非电毫秒雷管进行毫秒微差爆破,同时适当调小炮孔孔距。爆破后大石块用手持风钻钻眼、爆破改小,装碴采用挖掘机挖装、自卸车运输至填方地段。4.2.1.8 路堑边坡力求平顺光滑,无明显的局部凹凸差,边坡突出的个别欠挖部分,人工浅孔爆破凿除清理。边坡上出现的坑洼凹槽人工清除松动岩石,将基座凿平一定宽度的基座面后砌筑嵌补,要做到嵌体稳定、表面平顺、周边封严。4.2.1.9 路基底面用手持风钻钻眼,浅孔爆破开挖、清理至设计标高,对个别凹凸不平处用级配碎石填平。路堑侧沟用小炮爆破开挖成型。4.2.1.10 在施工中加强对边坡坡度的检测,随着
