2、:1/501.3 涵洞布置情况涵洞布置情况本项目沿线共布置 26 道涵洞,涵洞总长度为 1348.13m,其中 1-0.5m 圆管涵 24 道总长401m,1-1.0m 圆管涵 15 道总长 567m,1-1.5m 圆管涵 6 道总长 345m,1-2.5*2.0m 钢筋混凝土箱涵 1 道长度 35.13m。1.4 主要材料主要材料1)管身、箱体:C35 砼2)管身及箱涵钢筋:光圆钢筋采用 HPB300,螺纹钢筋采用 HRB4003)管涵基础、箱涵基础:C30 混凝土4)洞口边沟跌井、一字墙、洞口八字墙、洞口铺砌、截水墙:C25 混凝土1.5 设计要点设计要点1、本工程沿线涵洞涵顶以上填土均大
3、于 50cm,均为暗涵。2、所有涵洞水利计算均按无压力式涵洞设计,涵洞孔径设计满足无压力式要求。3、圆管涵按承载能力极限状态和正常使用状态两种方法分别对截面进行强度与裂缝宽度验算。4、箱涵作为超静定结构按矩形框架进行计算。顶板、底板以及侧墙按偏心受压构件配筋。当计算附加荷载组合时,温度应力按10考虑。二、施工注意事项二、施工注意事项1、涵洞设置位置及斜交角度可根据实际需要进行适当调整。为使水流顺直,进出口应根据需要进行适当的开挖。2、涵洞顶部以上填土(包含路面结构)的厚度应不小于 50cm。3、圆管涵施工时,必须注意管涵的全长和管节的配置及端墙位置的准确,按 2m 标准管节配置,余下不足 2m
4、 的管节,应在预制时予以考虑,不能随意将标准管节切断来使用。4、在整体式基础涵洞的涵台砌筑前,应在基础与涵台的接触面处将基础顶面进行正规拉毛处理,并且冲洗干净,以利于基础与涵台牢固结合。5、箱涵采用就地浇注工艺。全箱可分为二次浇筑,第一次浇至底板内壁以上 30 厘米,第二次浇筑余部分。两次浇筑的接缝处应有良好的衔接面(粗糙、干净并不得有堆落的混凝土、砂浆等)。6、拆除翼墙模板时要避免产生大的震动。翼墙、侧墙背后填土,应在涵身混凝土强度达到 100%设计强度时方可进行,要求分层压实,不得采用大型机械推土筑高一次压实法,也不得只在一侧压填,必须两侧对称进行。7、洞口与洞身应分开砌筑,缝内采用沥青麻
5、絮或其他有弹性且不透水的材料填充。8、涵洞洞身段的沉降缝一般沿涵长方向每隔 48m 设置一道,沉降缝必须贯穿整个涵台断面(包括基础),缝宽 2cm,沉降缝的设置应与板方向平行。凡地基地质发生变化,基础埋置深度不一或基础地基的承载力发生较大变化,以及基础挖深交界处,均应设置沉降缝。9、涵洞台后应采用透水性较好的碎石土回填,并应碾压到位,压实度不小于 96%。10、施工过程中,当涵顶覆土厚度小于 0.5 米时,严禁任何重型机械和车辆通过。S211钱塘段(江东大道至红十五线)公路工程第 1 页 共 7 页-路线左侧路线右侧左涵长右涵长总涵长1K9+075.19090钢筋混凝土圆管涵1-1.0m4.1
