25、缩缝或沉降缝一道,表面整平,待强度满足要求后拆除模型。基础混凝土在挡墙外5cm的前挡,与墙面板整体现浇。砂砾石垫层施工在粉喷桩达到规定龄期且试验合格后,进行砂砾石垫层施工。砂砾石在施工前应送检,试验合格后方可用于施工。1、人工配合机械整平场地,露出粉喷桩桩头,摊铺第一层25cm厚的砂砾石,人工配合机械整平,机械碾压,检查合格后铺5035土工格栅。2、土工格栅检查合格后,进行第二层砂砾石的施工。 加筋土工格栅的铺设土工格栅使用前应进行复试,性能(有效面积、抗拉强度、抗冻融循环性能、抗老化性能等)满足设计要求。土工格栅应与外界隔离储存,避免风吹、日晒、雨淋等自然侵袭,并在规定的期限内使用完毕。1、

26、铺设前应检查下一层填料的标高、平整度、压实度。2、铺设原则:按设计位置铺设土工格栅拉筋,施工时严格控制每填层的标高、填筑坡率,拉筋回折后与受力拉筋一起固定。3、拉筋采用经编土工格栅(80),设计长度5.5m,上下层间距0.3m,回折长度2.6m,回折反压总宽度不小于2m,其中回折包裹塑料编织袋装砂夹砾石压载宽度不小于0.5m,包裹压载后与拉筋叠合的长度不小于1.5m。4、筋材需要接长时,连接处强度不得低于设计强度。5、加筋铺设前,先填筑夯实至加筋所在标高,且自板向后逐渐升高,使筋带尾部比前端高0.1m,铺设格栅加筋带时应展平、伸直、不得有卷曲、扭结,纵肋方向垂直于墙前沿线。填土前设法张紧,使之

27、产生一定的伸长量,然后用长56cm“u”形骑马钉固定。6、未被填料覆盖的筋材上严禁施工机械行驶,拉筋上最少有0.2m厚填料时方可上大型机械。锚杆施工整体墙面与加筋土体的连接采用预埋20mm锚杆,纵向间距(顺线路方向)1.0m,每三层即0.9m预埋一排。1、锚杆表面先刷两层防锈漆,涂一层热沥青后用麻筋缠紧(麻布袋),再涂一层热沥青汁,伸入墙面部分不防腐。2、施工顺线路方向每隔1m按设计要求摆设1排,填至第三层再每隔1m按设计要求摆设1排。3、加筋土体施工完毕后,绑扎墙面板钢筋网,钢筋网应与锚杆连接在一起,所以在施工过程中注意锚杆弯钩的方向及伸入面板的长度。泄水孔施工在路基施工过程中,在墙面按纵横

28、间距1.0m上、下、左、右交错布置泄水孔,孔内预埋50mmPVC塑料排水管,排水管伸入加筋土体的管身设梅花形钻孔,并用针刺无纺布包裹,防止填料流失。填料填筑用于加筋土的填料一般要求是易于压实,能与拉筋产生足够的摩擦力,优选有一定级配的砾类土、砂类土;填料中不应含有地表的腐植土、草皮、树根等杂物;填料中不得含有粒径大于l0cm的尖棱状碎石。本段路基加筋土挡土墙填料决定采用A组填料级配砂砾石。以上条件均可保证。1、施工前通过压实试验取得工艺参数(分层厚度、碾压遍数等)及组织参数(人员数、压路机吨位等),用于指导施工。2、人工将砂夹砾石装入塑料编织袋,按设计位置码放整齐,宽度不小于0.5m,包裹压载

29、后与拉筋叠合的长度不小于1.5m。3、在每层两侧受力拉筋及袋装砂夹砾石铺设完成后,进行该层路基填筑,摊铺时严禁施工机械沿路基横断面方向推土,筋带以上摊铺20cm以上填料后方可行驶推土机,车辆机械一般不允许在未经压实的加筋体上行驶,尤其不得转弯、调头。4、压实机械采用光轮压路机(严禁采用羊足碾),碾压顺序为:拉筋中部-尾部-前部,先轻压后重压。碾压机械距整体路面板边缘距离不应小于1.5m,板后1.0-1.5m范围内采用小型机械压实或用人力夯实达到设计要求的密实度。整平压实后的路基面呈1%3%的“人”字形横坡。5、按规范要求检测地基系数K30值及孔隙率n值,合格后进行下一道工序施工。6、按设计和规

30、范要求设置路基沉降观测,施工过程中根据每天的测量情况控制加筋土体填筑速率,保证路基工后沉降15cm。石灰土封闭层施工加筋土挡土墙路基顶面铺设土工格栅范围内夯填石灰土封闭层,厚0.2m。加筋土体施工至设计标高后,夯填石灰土封闭层,施工时用土和消解过的石灰充分拌匀,人工摊平后机械碾压。找平层施工路基面设计为4%的“人”字形排水坡,石灰土封闭层及以下加筋土体填筑时横向排水坡不够,在填筑基床表层砂垫层前用A组填料找平至设计标高,做成4%排水坡。砂垫层、复合土工膜施工砂垫层厚0.1m,中间夹铺一层复合土工膜。施工前砂垫层、复合土工膜均送试验室试验,合格后方可使用。砂垫层先摊铺下层0.05m,人工挂线整平

31、并清除尖锐杂物及碎石,铺设经编复合土工膜。复合土工膜应平整无褶皱,铺好后及时摊铺上层0.05m砂垫层,避免阳光照射,以保证材料性能不受影响。基床表层施工路基基床表层为0.5m厚A组填料,施工前取样送检,试验合格方可使用。施工时分两层施工:下层厚0.2m,与0.1m砂垫层一起碾压;上层厚0.3m,一次摊铺成型碾压。路基施工过程中按规范要求进行试验,合格后进行下一道工序的施工。面板施工加筋土挡墙墙面设计为C25钢筋混凝土现场浇筑,厚0.15m,内置10mmHPB235级钢筋,纵横向间距0.2m。净保护层厚0.04m。浇筑时内壁不设模板,安装外模前用砂浆将塑料编织袋包裹体间空隙、不平处抹平,保证内壁

32、光滑。墙面板外模采用1.5m1.0m钢模拼装,施工前在平整的空地上按长15m、宽5m整体试拼,拼好后在模板面上焊10mm钢筋,棱形,拆模后既形成棱形凹下花纹,纹中勾色,以使墙面平整美观。1、施工时,加筋包裹体墙面在设计边坡率基础上再预留2的后仰坡,确保面板在工程完工后具有1:0.1的稳定胸坡,严禁面板前倾。2、加筋土挡土墙面板混凝土、帽石和基础每隔15m设0.02m宽伸缩缝,缝内填塞沥青麻筋;在面板内侧沿整个墙高设置宽0.3m的无纺土工布,防止填料流失。3、加筋土挡墙墙体完工后,待墙体变形完成后再开始墙面结构的施工,每次施工15m长,整体现浇:绑扎钢筋网与锚杆连接在一起预埋帽石砼接芷钢筋安装外

33、模并加固安装附着式振动器灌筑C25混凝土养护拆模下一墙面板施工。帽石、栏杆施工加筋土挡土墙墙顶设C15砼帽石及钢筋混凝土立柱栏杆,帽石为矩形断面:宽0.6m,高0.4m,分段长度与墙面板一致,即每段15m。帽石施工工艺流程为:安装、加固帽石模板预埋20mm “U”型螺栓并固定灌筑C15混凝土养护拆模下一段墙面板施工。待帽石混凝土达到设计强度后,安装栏杆立柱,栏杆安装保证外观质量,要求平、顺、直,施工时挂线调节。五、施工关键环节:1、拉筋是指80土工格栅,其施工是加筋土挡墙控制的关键,首先要从原材料入手,保证土工格栅的各项指标满足设计要求。2、拉筋与渗水土之间的摩擦力是挡墙受力平衡的关键,在施工

34、时要加强对渗水土的碾压,保证压实度符合规范要求,从而保证拉筋与渗水土间的摩擦力符合设计要求。3、80土工格栅的铺设是施工的要点,要掌握土工格栅铺设的方法,保证搭接长度和回折长度,以及大型机械施工时对土工格栅的破坏。4、路基填料的控制,加筋土挡墙填料以透水材料为主,要保证填料的质量。5、面板施工要保证外观质量,首先面板施工时要在路基填筑6个月后进行,要保证路基沉降趋于稳定,面板施工后不容易变形。而且混凝土外观质量要严格控制,并且镶嵌花纹。points before and after the echo, a connecting link between the preceding and th
