38、施工用材料水泥、钢筋、碎石、砂、片（块）石等已完成备料，经进场验证，各种进场材料产品合格证齐全，工地实验室已负责完成各种材料抽检试验，试验结果合格；并完成了砼、砂浆配合比试验。材料产品合格证、抽检试验报告、砼砂浆配合比报告已送监理工程师审核。后勤保障及临时设施已准备就绪，施工管理人员、施工机械及测量设备、劳动力等已按计划到位，具备开工条件。四、工程内容测量放样基坑开挖基坑清理、验收基础砌筑台身浇筑盖板预制及安装防水层及沉降缝处理进出口铺砌台背回填及其它附属工程。五、详细施工方法和工作程序该分部工程开工前项目部组织人员认真复核设计图纸、熟悉技术文件及规范，做好技术交底工作，明确分工，将责任具体落

39、实到人，避免管理混乱影响施工。严格材料进场制度，不合格品不得用于施工。施工过程中认真做好各项隐蔽工程原始数据资料及隐蔽工程照片资料，真实反应施工质量。A、基坑开挖1.涵洞挖基前，首先要作好改移沟渠，地面临时排水措施，防止流水流入基坑，浸泡基底。根据施工图纸，核实原沟底或通道标高与新建涵洞出入口流水标高是否相符，并将计算与测量标高上报主管工程师，保证建成的涵洞通畅，不积水。2.基坑开挖的位置、深度、基底尺寸必须符合设计的要求。开挖中如发现水文、地质与图纸不符时，根据开挖的实际情况，及时请现场工程师及监理提出处理措施。基坑开挖时，做好涵洞中线定位控制桩以及高程控制桩，土方开挖采用机械、人工配合开挖

40、，边坡视实际土质按1：0.331：0.75放坡，挖出的土石方及时运离基坑5米以外。对于边坡稳定性差或陡峭地段采用钢管木板临时防护，保证施工安全。机械开挖接近涵洞基底设计标高时采用人工清理，避免超挖、扰动基底土质；涵洞基坑断面、涵底高程应满足设计文件、规范要求。开挖土方应及时运离涵洞边缘，不得在基坑边缘过高堆土，废方应及时运到指定弃土场，测量人员应随时掌握及控制开挖宽度及深度。3.基础轴线位置，应经校核无误后再进行挖，为了便于校核，轴线控制桩延长至基坑以外加以固定。在开挖过程中，要经常复核轴线及基坑尺寸，保证施工准确。4.挖基时基底不得扰动或被水浸泡。挖至接近基底标高时，保留2030cm厚原状土

41、，在基础施工前突击挖除，并进行夯实，承载力检测合格后，随即进行基础砌筑。5.在基坑内及基坑范围外3m（根据实际情况）设置积水坑及截水沟，保证基底不积水。6.基坑挖至设计标高后，应立即进行地基承载力试验，如果地基承载力达不到设计要求，根据设计单位、业主、监理单位意见进行换土或其它加固措施等变更处理。基底平整、密实、无杂物、无积水，经监理工程师检验签认后，方可进行基础圬工施工。基础位于填筑路基时，基础施工前必须将基底充分压实，为避免涵身因不均匀沉降产生裂缝。检验基底平面位置、尺寸、基底标高，其允许偏差及检查法如下表：项次检查项目规定允许偏差（mm）检查方法和频率1基底平面尺寸长不小于设计尺量，长、

42、宽各3处宽不小于设计1轴线偏位25用经纬仪纵横各2点2基底高程土质50水准仪测58点石质+50、-200检查基底地址情况和承载力是否与图纸相符。检查基底处理和排水情况是否符合规范要求。检查施工日志及有关试验资料等。经过检验不符合图纸要求时，应按监理工程师的指示处理，直至检查符合要求后方可进行下道施工。B、基础砌筑在监理工程师对基槽中线、高程、几何尺寸、地基承载力等验收合格后方可进行涵洞基础及台墙施工。由施工测量人员做好断面控制桩以及高程控制桩，做好施工技术交底。涵洞基础为浆砌块石，做好砂浆施工配合比和拌合料计量工作，报监理工程师批准后实施。施工过程中应严格控制砂浆配合比，不得使用人工拌和砂浆，

43、砂浆拌和料应当天拌和当天使用。浆砌块石时，应利用块石的自然形状，相互交错衔接在一起。施工时，最下一层石块大面必须朝下，做成犬牙交错且搭接紧密，同时在砌下面石块时考虑上面石块如何接砌；注意到砌石分层错缝、咬扣紧密；嵌缝饱满、密实，不得有空洞；在砌角石、面石时应选取比较方正石块。砌腹石时可供应不规则但形状尺寸适宜的石块。角石、面石应首先选取备用。砌体下层应选用较大的石块，向上逐渐用较小尺寸石块；一天中完成的砌石高度不宜超过1.2m。气温较低时当天的砌筑高度还应减少；不准在已砌好的砌体上抛掷、滚动、翻转或敲击石块。在砌筑过程中严禁振动下一层砌石。砌体每层砌完在砂浆初凝后马上进行覆盖洒水养护。养护期不

44、少于7天。C、墙身片石砼浇筑在基础砌体砂浆强度达到一定强度后进行砼墙身施工。1、墙身模板支设墙身模板采用标准钢模板拼装，利用销钉在现场连接并用48钢管架做拉杆及加劲支撑。组成的墙身模板，应严格按墙身结构尺寸立模。模板应支撑牢固、板面平整、接缝严密不漏浆，并应防止因跑模引起结构砼外形缺陷。涵洞墙身砼为1层，因此支模时根据墙身高度，分层支设，为防止跑模，一次支设不超过2米，采用双排48钢管架作为模板支撑。为保证第一层砼几何尺寸，采用在基础打孔埋置脚手架和在基础内插筋，用于加固模板，保证模板不爆模，在浇筑第一层砼完时，在其砼上插入25短钢筋，用于第二层砼模板的加固处理，模板的自身要具备足够的强度、刚

45、度及整体性，模板的支撑应具备稳定性，模板的内表面应光洁平整，并应涂刷脱模剂，模板的支架应置于平整坚实稳定的地基支撑点上，模板的整体稳定性是由支架来保证的，模板支架与操作支架及管道输送支架应分开各自形成不同的体系。模板安装在施工中应注意以下几个问题：（1）模板采用拼装式整体钢模板，每块模板的面积不小于1.0m2。（2）模板正式安装前，在现场组拼好，并保证模板的局部和整体强度与刚度。（3）在现场组合好大块钢模后，检查接缝及平整度。 （4）在基础顶面外边线处钻孔，预埋钢筋，以便在侧模安装时，侧模内边底边缘靠紧该钢筋，便于固定基础的侧模底线。 （5）通过对拉螺杆或钢管架固定钢模外背楞。同时在外侧加枋木

46、或钢管斜支撑。（6）模板安装完成后，在顶标高处标注。 2、片石砼浇筑开工前，根据设计文件，按照普通混凝土配合比设计规程（GBJ55-2000）要求完成混凝土配合比设计并报监理工程师批准。（1） 水泥、集料、水：制拌前按照公路工程水泥混凝土试验规程(JTJ053-94)、公路工程集料试验规程(JTJ058-2000)和公路工程水质分析操作规程(JTJ056-84)对组成混凝土的水泥、粗细集料、水等进行试验，并把结果报送监理工程师；不使用不合格材料。（2）混凝土的拌合、运输：混凝土在拌合站集中制拌，然后运输至施工现场。（3）混凝土浇筑：运至现场的混凝土立即进行浇筑施工，入仓高度超过2m的部位采用溜

47、槽或者导管等辅助设施，避免离析；入仓采用平铺法，人工平仓，涵台两侧同时对称进料，分层浇筑；混凝土浇注过程中，将选好的片石放入模板之中，均匀摆放，片石含量不超过30%，采用软轴插入式振捣器振捣密实，间距不得大于振捣器振动半径，避免漏振；混凝土连续浇筑，避免间断，若因故必须间断，间断时间不得大于混凝土初凝时间，否则按照施工冷缝处理。（4） 拆模、养护：待混凝土强度达到0.20.5MPX后方可拆模，脱模后立即对表面的缺陷予以修补，之后用草帘或麻袋覆盖，洒水进行养护，养护天数一般为714d。3、涵洞基础以及台墙位置、断面尺寸、高程、沉降缝位置等均应满足设计文件、规范要求，洞身每隔46米设置一道沉降缝，

48、缝内填以沥青麻絮或不透水材料。并经监理工程师验收合格。注意在施工过程中准确掌握天气情况，合理计划控制每天砼、砂浆需要量，以免由于天气影响施工质量达不到设计、规范要求。4、台帽及帽石施工时应注意其高度、坡度、断面尺寸及准确位置，避免影响盖板的准确安装。钢筋砼盖板预制时，应认真复核其断面几何尺寸、钢筋种类及安装位置，砼强度达到70以上时才能进行盖板的安装。钢筋、砼施工及构件安装均应符合设计、规范要求并经监理工程师验收合格。5、涵洞洞口建筑及附属结构包括一字墙、洞口铺砌、锥坡、截水墙、铺底等。在进行洞口建筑及附属结构施工时测量人员应准确控制其位置、高程、断面及细部尺寸，质检人员应认真复查、复核，加强监督管理职能。各项检查指标以及外观质量应符合设计、规范要求，自检合格后及时报检监理工程师，经监理工程师检验合格后方可进行下一步施工。D、盖板预制及安装1、预制场设
