16、汽车 10 台湖北新绿6000L洒水汽车 2台三、主要施工工艺控制1、施工准备(1)原材料检验:对料场的石灰、粉煤灰、碎石分别取样检验,原材料均需满足相关的技术规范及设计文件的要求,对于不合格的材料坚决不允许进场、使用。(2)对于二灰碎石施工中所用的机械设备进行全面检查,使机械保持良好的工作状态。(3)清扫下承层表面杂物。(4)正式施工前,要进行图纸会审、技术交底,明确分工,使每一位参加施工的人员都清楚应该干什么,怎么干,应该达到什么样的标准。对于各道工序的关键环节,请有经验的技术人员指导操作,解决施工中出现的问题。2、测量放线在底基层上恢复中线,直线段10-20m设一桩,平曲线段每10-15
17、m设施工控制桩,并在施工控制桩外30cm打设双向紧固钢钎,施工控制高程用钢丝线按设定高程在钢钎横杆上设定基准线,作为摊铺机摊铺的导线及高程控制线。3、二灰碎石拌和(1)利用600t/h稳定碎石拌和站进行二灰碎石拌和,拌和站设一名试验人员控制二灰碎石混合料的含水量以及各种材料的配合比。(2)各料斗配备12名工作人员,时刻监视下料情况,并人为帮助下料,在石灰、粉煤灰料斗安装振捣器,帮助下料,不准出现卡堵现象,否则及时停拌。(3)拌和时含水量应高于最佳含水量1-2%。4、混合料运输利用10辆自卸汽车运输、尽快将拌成的混合料运送至铺筑现场,运送车的混合料应该用蓬布覆盖,减少水分损失。5、二灰碎石摊铺(
18、1)摊铺前将底基层表面湿润。(2)采取摊铺机摊铺,摊铺速度均匀,尽量避免停机现象。(3)根据以往的施工经验,初定1.35的松铺系数。6、二灰碎石碾压(1)根据压路机的宽度和轮距的不同,制定碾压方案,应使各部分碾压到的次数尽量相同,路的两侧应多压2-3遍。(2)整形后,当混合料的含水量为最佳含水量时,应配合压路机进行全宽碾压。直线段由边缘向中心线碾压,超高段由内侧向外侧碾压,每道碾压应与上一道碾压相重叠1/2轮宽,碾压时先用振动压路机静压1遍,后振压3-4遍,接着用平轮压路机静压2-3遍,消除轮迹。压路机的碾压速度,头两遍采用1.5-1.7km/h,以后采用2.0-2.5km/h。碾压过程中应随
19、时检测压实度,使每层整个厚度和宽度完全均匀的压实到规定密度为止。压实后表面应平整、无轮迹或隆起、裂纹搓板及起皮松散现象,压实度需达到重型击试验确定最大干密度的96%以上。碾压过程中二灰碎石的表面层应始终保持湿润。如果表面蒸发过快,及时补洒少量的水。(3)严禁压路机在已完工的或正在碾压的路段上调头和急刹车,以保证基层表面不受损坏。7、现场检测(1)松铺系数的测定:摊铺前,按20m一个断面,每断面三个点标记检测,测量并记录其高程;摊铺后,恢复标记点并测量记录其高程;碾压完成后,再次恢复标记点并测量其记录高程。根据三次记录的高程差确定二灰碎石的摊铺系数。(2)压实遍数的确定:在强振完成第二遍后每碾压
20、完一遍进行一次压实度的检测并记录,根据记录整理压实度压实遍数曲线,确定最佳压实组合及压实遍数。8、接缝处理1)、横向接缝:(1)两个工作段搭接部分,应设置横向接缝,人工将末端含水量合适的混合料弄整齐,紧靠混合料放两根方木,高度与混合料的压实厚度相同,并整平紧靠方木混合料。(2)方木的另一侧用砂砾回填约3米长,其高度约高出方木几厘米。(3)将混合料碾压密实。(4)如在重新开始铺筑混合料之前,将砂砾和方木除去,并将下承层表面打扫干净。(5)如在碾压后末端成一斜坡,则在第二天开始铺筑新的混合料之前将末端成斜坡挖掘除,并挖成一条垂直向下的断面。2、纵向接缝:(1)在前一幅施工时,在靠中央一侧用方木或钢
21、模板做支撑,方木或钢模板的高度与稳定碎石层的压实厚度相同。(2)养生结束后,在铺筑另一幅之前,拆除支撑木或钢模板。9、养生和交通管制:(1)碾压完成并经检测压实度符合规范要求,即可开始养生,采用洒水的方法,并在整个养生期间保持表面潮湿状态,养生期不少于7天。(2)养生结束后,将稳定碎石表面清扫干净,并尽早喷洒热沥青下封层。(3)在整个养生期间,除洒水车外,应封闭交通,不能封闭交通时,禁止重车通行,其他车辆的车速限制在30km/h以下。四、质量检验标准按JTG F80/1-2004公路工程质量检验评定标准、JTJ 034-2000公路工程基层施工技术规范和施工指导书的要求,对标高、横坡、宽度、平
22、整度、压实度、无侧限抗压强度等指标进行检测,发现不合格的及时处理,并作出相应的措施调整。石灰稳定碎石基层实测项目项次检查项目规定或允许偏差检查方法(每幅车道)1压实度(%)代表值98按附录B检查,每200m每车道2处极值942平整度(mm)83m直尺:每200m测2处10尺3纵断高程(mm)+5,-10水准仪:每200m测4个断面4宽度(mm)符合设计要求尺量:每200m测4处5厚度(mm)代表值-8按附录H检查,每200m每车道1点合格值-156横坡(%)0.3水准仪:每200m测 4个断面7强度(Ma)符合设计要求按附录G检查五、工程质量保证措施(一)质量目标为确保建设的质量,实现分项工程
