36、8.3.1 盲沟排水是通过采取有效措施，使含水量较高的路基保持在允许含水范围内，保证路基安全和路基处于稳定状态，满足使用要求。施工前应据设计图纸，认真施工，并认真做好路基临时排水。8.3.2 施工放样：必须在路基挖除软土后，换填至盲沟设计标高。8.3.3 开始准确放样，精确测定盲沟起止点，沟底纵坡，两端衔接是否顺直，和其他支盲沟是否能够很好的连接。8.4 材料要求8.4.1 片石：采用爆破法或楔劈法开采的片石，厚度不小于15cm,其宽度与长度不小于厚度的1.5倍，无锋棱凸角，顶面及底面大致平行；尺寸较大，并稍加修整，其强度不小于30Mpa。 8.4.2石料应强韧、密实、坚固耐久，质地适当细致，

37、色泽均匀，无风化剥落和裂纹及结构缺陷。石料的运输、储运和处理，应不使有过量的损坏和废料。8.5 施工方法8.5.1盲沟设计为梯形，在盲沟的底部用片石填筑，粒径150mm-400mm。片石表面应清洁，片石摆放铺设采用人工铺设。片石铺设应整齐规范，孔隙应清晰以便保证流水通畅。8.5.2盲沟的设置深度，应满足渗水材料的顶部不得低于原有地下水位的要求。当排除层间水时，盲沟底部应埋设与最下面的不透水层上。8.5.3当采用土工织物作反滤层时，应先在底部及两侧沟壁铺好就位，并预留顶部覆盖所需的土工织物，拉直平顺紧贴下垫层，所有纵向或横向的搭接缝应交替错开。搭接长度均不得小于300mm。8.5.4盲沟只宜用于

38、渗流不长的地段，且纵坡不小于1%。8.5.5 土工布铺设：本工程土工布铺设要求在片石填筑完毕，土方填筑之前铺设，铺设宽度符合要求、搭接正确。土工布在铺设之前要求先检查片石表面平整度、高度、有无带尖棱硬物，表面要求人工整平、把不平处凹凸处用小碎石填平。铺设时要求施工技术人员所放边桩进行控制铺设位置。技术人员所放边桩距土工布边30cm，每20米个边桩，铺设时先把土工布打开，土工布拉开后用4人拉直，按边桩用钢尺把两边尺寸先放对，然后按控制桩把中间土工布调直，调直完毕后用土把土工布四周盖一下，以免被风吹起。铺设完毕后应经监理工程师合格后方可进行路基填筑施工。8.6质量保证措施8.6.1 基础开挖后，工

39、程施工人员应时刻把好质量关，每道工序经质检、试验、测量等检测人员到场，检查他们责任范围内的工序质量合格，并经监理工程师签证认可后，方可进行下一道工序。8.6.2 该工程所用的碎石材料等都应取得检验合格证方准运进场。否则，拒绝签收签证、验收，更不能使用。8.6.3 若遇雨季施工时，应加强排水措施的处理，以防雨水冲刷基础，影响工程质量。9.路堤填筑试验施工工艺及控制要点 9.1第一层填筑地基承载力达到要求后，开始进行路基本体第一层填筑。所用的填料为B组填料,来自K273+780-K273+953挖方段。9.1.1 由路基队测量人员负责测量工作，采用在两端立杆引桩保护的措施，随时控制并恢复试验段中线

40、，确保中线准确。由技术员按5m的间距在已整平压实的基底上用石灰撒线布置方格网。同时测量各网格交叉点的高程，记录为第一层的底面高程。9.1.2第一层摊铺整平：预计松铺厚度40cm，自卸车装运料10.0m3, 为便于控制松铺厚度，经过计算每格方格网面积为25 m2，设置每方5m5m,每个方格填料1车（由卸时装载机控制）。车运料，现场设一名专人负责指挥依次倒料，上料结束后，用推土机摊铺，人工配合找平。填料时用竹签做标记，用插入法和边桩控制松铺厚度并做成2的横坡。摊铺时随机取样，用炒干法现场进行含水量检测，现场检测的含水量与最佳含水量比较偏差，规定允许偏差在-3+2%之内。如大于最佳含水量，则采取摊铺

41、晾干等方法，如低于最佳含水量，则进行洒水湿润。9.1.3测量放线布网格：在松铺整平的填料上放线撒石灰布网格。网格布完后，测每个网格交叉点的高程，记为第一层的松铺高程。网格形式和高程测量顺序上述执行测量程序。9.1.4碾压填料在整平后，进行碾压前对填筑层的厚度和平整程度进行检查，确认层厚和平整程度符合要求方可进行碾压。先用推土机对表面进行预压，然后再用振动压路机压实，压路机吨位采用20t。碾压遍数：根据土质情况，碾压遍数由压实度确定，初步确定为5遍：第一遍静压，第二遍弱振，第三遍、四遍强振，第五遍静压，按试验检测标准选择四个断面（12个点）检测孔隙率n，孔隙率如果满足基床以下路基填筑设计要求，测

42、量其压实高程，并记录测量数据。检测完成后，再进行碾压，初步确定2遍，第一遍强振，第二遍静压，按试验检测标准选择四个断面（12个点）检测孔隙率n，孔隙率如果满足基床底层填筑设计要求，测量其压实高程，并记录测量数据。压路机行走速度：不大于2km/h。碾压方式:由两边向中间纵向进退式进行，沿线路纵向行与行之间横向重叠压实0.4-0.5m，前后相邻两区段纵向重叠碾压长度不小于2m，并对路肩部分450碾压法碾压，确保边坡碾压密实，做到不漏压，不留死角，确保碾压均匀。 9.1.5检测项目及压实标准基床以下路堤检测项目及压实标准项 目压实标准检测数量碎石类及粗砾土地基系数K30（Mpa /m）110每填高0
