泵站HDPE双壁缠绕管牵引施工（完整版）

1、泵站 HDPE双壁缠绕管牵引施工第一章工程概况1.1工程概况 :*泵站一段重力截污管 (HDPE双壁缠绕管，管径 DN700)和*涌北岸的一段重力截污管 (HDPE双壁缠绕管，管径 DN600)，采用牵引法进行施工。1.2牵引法施工工艺的选择重力截污管段有 740多米长管道是紧靠 *高速公路边。原计划采用明开挖施工，采用密扣拉森钢板桩支护。根据地质报告，该段地质情况较为复杂，地下水丰富。管道位置土层为人工填土及淤泥、淤泥质土，边坡稳定性差。管道埋深在地下6米左右。刚好处于砂层表面，砂层含水量较为丰富，而且为强透水层，极容易产生管涌和流沙现象。即使采用钢板桩支护一但发生管涌现象，仍会对附近造成地

2、面下沉。这样势必使离基坑边不到 3米的高速公路路面开裂，造成不可估量的损失。根据现场管线探测和摸查，在 HDPE管顶上 3米处有一条与它同线埋设中国电信的管线，如果还在该处进行明开挖施工，必先要进行电信管迁移。增加了投资和延误了工期。鉴于以上理由该段原明开挖施工方法不可行，固改用对周边土体影响小，施工工期短的牵引法施工。*涌北岸段管道位于 *路上，由于紧靠 *涌，原计划采用明开挖施工时，管坑宽度为 4.6米，基本占用了 *路整个路宽，要破坏两边大量绿化， *涌重力砌石挡墙等。为了节省投资，缩短工期也改用牵引法施工该段截污管。1.3水文、地质情况1、地质情况 根据勘察范围的岩土的工程特征，成因和

11、为所需敷设管道的中心线。3、扩孔、成孔在孔洞形成后，将导向头卸下，装上一钻头，钻头孔径比孔洞大1.5倍，然后将钻头往回拖拉至初始位置，卸下该钻头，换上更大的钻头，来回数次，直到符合回拖管道要求。为了防止塌孔，在注射的水中加入外加剂，该外加剂有固化洞壁。润滑钻杆等作用。4、牵引管道钻孔完成后，将管材按连接成需要长度，将管材两端封闭，一端与钻头相连，将其一次性拖入已形成的孔洞中，即完成整个埋管工序。5、砌筑检查井 牵引管施工完成后需要进行检查井施工，在牵引管末端砌筑检查井。6、验收根据设计及验收规范进行闭水试验等验收工作。2.2管材的选择upgrading of enterprises.

17、符合以下要求1、抗外压能力强，能承受较大拉力的管材。2、具有较好的柔韧性，能较好的适应沉降，从而提高管道的抗震能力。3、单位重量轻。在牵引过程中减少与孔壁的摩擦力，提高施工效率和节约成本。第三章主要施工技术措施3.1施工准备工作1、地下管线测量 :a(图纸校核 :到规划局查阅工程施工地点的管线布置情况，并在现场进行校核，在现场找出图纸标示的管线。b(现场探测 :利用地下管线探测仪器对地下管线的分布、位置、走向、管径进行调查探测。c(联系管线单位 :主动联系各管线单位到现场确认和交底。d(管线调查清楚以后，按照供水管顶进的路线描绘地下管线和地下障碍物的布置图。2、钻杆轨迹设计根据地下管线布置图设

18、计钻杆的钻进轨迹。轨迹包括两个部分，造斜段和铺设段。因为该段管为重力流截污管，必须按设计流水标高埋设，埋深的按照设计提供的流水标高确定。造斜段 :1(造斜段距离 L: 0.5 -h) L,h(2R1式中:h埋深， R造斜段曲率半径，取 1200d,代入数据计得 L,22米 12(钻杆入射角 a:-10.5 a,0.5tgh(2R-h)/h 1o式中各字母意义同上式，计得 a,41。3.2工作坑施工方案每段牵引需要挖掘 2个工作坑，包括入口工作坑、出口工作坑。均采用机械挖掘，采用密扣钢板桩支护。入口工作坑是为了检测钻杆的钻进角度和旋转扭动等工作状态而设的工作坑。在钻机前面 6,10米处挖掘。尺寸

19、为 1.5米，挖深由地面渐变到深 4.5米。施工工序为 :破除路面 ?打钢板桩支护 ?挖土?清运余泥 ?工作坑围蔽。人工挖泥过程注意不要损坏人行道的地下管线。出口工作坑是回拖时提供排水管入洞工作坑，出口工作坑尺寸和施工方法与入口工作坑相同。3.3钻进技术方案导向钻机的主要部件为 :轮式钻机、操作系统、动力站、液压系统、钻头、钻杆等，对照安装使用规范进行安装。钻机运到现场必须先锚固稳定，钻机如果锚固不稳，将会发生功率损失或者功率作用在机器身上，造成机器和人的伤害。钻机是依靠地锚座和后支承与地基固定的，安放钻机前应先平整场地，根据预先设计的的钻机倾斜角度进行调整，依靠钻机动力将锚杆打入土中，使后支

26、中通过地面精密接收仪器，通过接收仪器数据调整钻头角度，使得钻进按照流水线标高路线前进。到达出口工作坑，完成钻孔工序。(一)钻进操作 :1.检查钻机的测量仪器的电源是否充足，不足的更换电池，特别是探头电池更不可马虎。2.按照测量仪器使用规范操纵仪器。3.探头装进探头盒内，打开接收机和同步显示器，转动探头盒检查仪器是否正常。4.把探头盒与钻头接好并连接在钻杆上，开机输送钻进液，检查钻头喷嘴是否畅通。5.启动机器进行造斜和水平导向钻进。钻进操作需要注意的事项 :1.钻杆的上、下接头对正，边缓慢给进动力边慢转上扣，不得拧得过紧。2.不允许使用弯曲和有伤的钻杆。3.钻进速度不宜过快，应根据地层条件合理调

27、定给进力。4.造斜顶进时，每次顶进进尺控制在 0.5m左右为好，曲线要缓。5.钻杆内不得进脏物，以免堵塞钻头喷嘴。6.当机油压力报警指示灯亮时，说明油压不正常，要进行检查。 7.当机油堵塞报警指示灯亮时，要更换机油滤心。8.改变水泵排量时，先摘开离合器，不得带速换档。9.当水泵较长时间不工作的情况下，应将其变速箱挂空挡，后合上离合器，以保持离合器操纵系统中的分离轴承。10.按规范开动钻机后，不允许马上用全负荷钻进，必须先进行试运转，确定各部分运转正常后，方可开始钻进。(二)钻头位置监测钻机随机配有一手提式地表导航仪，用以确定钻头在地底的位置，监测钻头是否偏离设计轨迹。在造斜段，钻头每钻进 10

28、cm就测一次钻头的位置，在平铺段每隔 20cm就监测一次。如果发现偏离轨道，就通过调整钻头斜面的方向，进行纠偏。但纠偏不能太急，因为钻杆毕竟具有一定的刚度。应该在几根钻杆内完成纠偏，不能在一根钻杆内完成纠偏，同时也要注意不要纠偏过度。(三)回拉扩孔钻头到达出口工作坑，钻进工作完成，但是孔径还没有达到铺设要求。本工程拟多次扩径，第一次扩孔为 200mm，第二次扩孔为 400mm，如此类推，扩孔到1000mm。具体操作为 :卸下钻头，在钻 upgrading of enterprises.

34、扩头回拉到达接驳坑，在接驳坑卸下 200mm的回扩头，再在出口工作坑的钻杆尾端接上 400mm的回扩头，如此扩孔到 1000mm。 (四)注浆和泥浆的处理在钻杆回拉扩径的过程中，必须通过钻杆注入膨润土浆，以减少摩擦，降低回转扭矩和回拉阻力，同时膨润土浆还有固壁防止孔洞塌土、冷却钻头的作用。更重要的是通过旋转回扩头切削下来的泥土，会溶融在膨润土浆里，形成泥浆，流到出口工作坑的集浆坑里。集浆坑里放设泥浆泵，把泥浆抽到泥浆池。3.4回拉敷设管道 扩孔成功到 1000mm后，可以进行回来管道工序。在回拖前要进行管线连接的工序，用热熔法将双壁缠绕管连接成与成孔长度相当的管道。准备好后，将管道与扩孔器相连

44、，特别是管底两侧，用砂浆碎砖捣插密实，其余逐层将砖砌包妥当，务使不渗漏。 (四)、砌筑圆形检查井避免上下层砖块对缝。检查井内外批档，每砌筑高即批档一次，做到随砌随抹灰，以减少砌井过程中的抽排水量。(五)、HDPE双壁缠绕管伸入检查井内的部份，应剪切到与内壁齐平。50cm(六)、各种井每天的砌筑高度，不超过 2m。每天砌筑结束时，清除跌落在井内的灰浆砖碎。整个井砌筑完成后，清除井内脚手架、垫脚砖、临时堵水基或导槽，并封堵脚手眼。 upgrading of enterprises.

50、即在管材或管件与井壁相接部位的外表面预先用聚氯已烯粘接剂、粗砂做成中介层，然后用水泥砂浆砌入检查井的井壁内。中介层的做法是先用毛刷或棉纱将管壁的外表面清理干净，然后均匀地涂一层聚氯已烯粘接剂，紧接着在上面甩撒一层干燥的粗砂，固化10,20min，即形成表面粗糙的中介层。中介层的长度视管道砌入检查井的长度而定，可采用 0.24m。(九)、检查井底板基底的砂石垫层应与管道基础垫层平缓接顺。管道位于软土地基或低洼、沼泽、地下水位高的地段时，检查井与管道的连接，宜先采用管采用中介层法与0.5,0.8m的短检查井连接，后面接一根或多根 (根据地质条件 )长度不大于 2.0m的短管，然后再与上下游标准管长
