39、、高边坡路基土石方施工方法 4.1、土质路堑开挖(1)、土方路堑开挖应根据地面坡度、开挖断面、纵向长度及出土方向,结合土方调配距离,选用安全、经济的开挖方案。 (2)、可作为路基填料的土方,必须分类开挖和使用,非适用材料作弃方处理。 (3)、较短的路堑采用横挖方法,路堑深度较大时,分成几个台阶进行开挖;较长的路堑采用纵挖法,按横断面全宽纵向分层开挖或采用通道式纵挖法开挖;超长路堑采用分段纵挖法开挖。 (4)、土方开挖应自上而下进行,不得乱挖、超挖,严禁掏底开挖;开挖坡面必须一次性成形。 (5)、必须根据现场实际情况,采取临时排水措施,将水导入路基排水系统,确保施工作业面不积水。 (6)、开挖过

40、程中,必须采取措施保证边坡稳定;开挖至边坡时预留至少30cm,保证刷坡过程中设计边坡线外的土层不受到扰动,同时对已开挖的坡面进行复核,确保开挖坡面不欠挖、不超挖。4.2、石质路堑开挖 (1)、开挖石方应根据岩石的类别、风化程度和节理发育程度等确定开挖方式;软石或强风化岩石,采用机械直接开挖,作业方式可参照土方路堑开挖进行;机械不能直接开挖的石方,采用爆破法开挖。近边坡部分采用光面爆破或预裂爆破。 (2)、爆破法开挖石方路堑施工: 1)、施工前必须调查爆破区内有无空中缆线并查明其平面位置和高度;调查地下有无管线并查明其平面位置和埋置深度;同时应调查开挖边界线外的建筑物结构类型、完好程度、距开挖界

41、距离等。 2)、爆破一般情况下宜采用中小型爆破,只有当路线穿过孤独山丘,开挖后边坡不高于6m,且根据岩石产状和风化程度,确认开挖后边坡稳定,方可考虑大爆破方案。 3)、根据确定的爆破方案,进行炮位、炮孔深度和用药量设计。设计时应考虑以下几点: a、应充分重视开挖边坡稳定,开挖风化较为严重、节理发育或岩层产状对边坡稳定不利的石方,宜用小型排炮微差爆破。 b、当岩层与路线走向基本一致,倾角大于1度,且倾向公路或者开挖边界线外有建筑物,应在开挖层边界,沿设计坡面打预裂孔。 c、按岩石外表、节理、裂隙等情况,分别选择正炮眼、斜炮眼、平炮眼或吊眼等。 4)、布孔与钻孔 a、爆破施工员、测量员按爆破设计放

42、出炮孔位置并标注,由钻工按要求钻孔,钻孔机械可选用冲击式钻机或潜孔钻;钻孔过程中严格控制孔位偏差和倾角。 b、钻孔完成后,应对炮孔内的废碴予以清除,由质检人员逐个检查孔距、排距、孔深、倾斜度等并与设计值对比,符合要求后,方可装药。 c、炮孔装药、堵塞、起爆网络连结必须由持有爆破证的专职爆破员作业,起爆必须由爆破负责人统一指挥。 5)出渣 a、须确认已经解除警戒,作业面上的危石检查处理后,清理出渣人员和机械方可进入现场。 b、开挖石方横向调整或小于100m 的纵向调运,可用推土机推运,需要纵向远运时,用自卸汽车运输;对大块石料,可集中用凿岩机改小。 c、石方开挖可分幅或分段进行爆破,石方清除和打

43、炮眼可轮流作业。 d、采用机械清碴时,应从上至下分层进行,严防滚石、坍方伤人损机。 (3)石质路堑边坡清刷 1)、石质挖方边坡应顺直、圆滑、大面平整;边坡上不得有松石、危石、凸出于设计边坡线的石块,其凸出或超爆凹进尺寸均不应大于2Ocm;对于软质岩石,凸出及凹进尺寸均应不大于10cm。 2)、挖方边坡从开挖面往下分级清刷,每下挖2-3m 时必须对新开挖边坡刷坡,软质岩石边坡用机械清刷,坚石和次坚石可使用爆破清刷边坡,同时清除危石、松石;清刷后的石质路堑边坡不陡于设计规定。 3)、石质路堑边坡如因过量超挖而影响上部边坡岩体稳定时,应用浆砌片石补砌超挖的坑槽。4.3、深挖路堑 (1)、在施工前详细

44、复查深挖路堑地段的工程地质资料,包括土石界限、风化破碎程度、土层有关特性,以及不良地质、地下水情况等。 (2)、开挖前,必须先修筑坡顶的截水沟。施工过程中应逐级开挖,根据开挖情况随时进行地质核查。定期对边坡坡度进行测量,并及时加以修正。 (3)、深路堑开挖应遵循及时开挖及时防护的原则,每开挖到一级台阶时应立刻进行防护工程的施工。 (4)、开挖时必须设置临时排水沟,将路堑内积水排出路基以外。每一级开挖完成后,及时按设计修筑平台排水设施。4.4、高边坡路堑施工(1)、路堑土方施工中,当运距短时及在绕行段结束地段,路堤需要填筑时,可采用推土机推运,将土料推至路堤经改良后做路堤填料。当运距较远,超出推土机经济运距时,采用挖掘机、装载机配自卸汽车进行土方挖装运卸施工。边坡采用人工配合机械施工,进行刷坡,修整边坡,达到设计边坡率和保持坡面平顺完整,有利边坡挡护施工和降低成本,并保证外观质量。 (2)、边坡开挖施工顺序:开挖时由上而下,纵向拉槽,横向分区、分层开挖。每次分层厚度为23m。靠近营业线侧采取预留隔离墙法施工路堑施工中
