(8)吊放钢筋笼、安放导管、二次清孔
A、所有钻孔桩的钢筋笼均在钢筋加工场内加工成形。吊装采用钻机架完成，有效桩长12米以内直接下笼，有效桩长12米以上进行一次井口对接。吊装时钢筋笼中心应与孔位中心重合，钢筋保护层采用砼圆饼，圆饼半径为设计保护层厚度（75mm）；布置数量按规范要求每节钢筋笼垫块应不少于2组，每组三块，应均匀分布在同一截面上，钢筋笼单节长度大于12m，应增设一组。以确保钢筋笼在孔中的位置。底钢筋笼吊放接接近护筒口，露出孔口一米左右，用钢管横穿钢筋笼架立在护筒口上，保持固定，接着吊装第二节钢筋笼，上笼与底笼中心线应垂直、重合。对接完成经业主专业工程师和监理验收合格后，钢筋笼顶标高下设计桩顶标高。用水准仪抄出护筒孔口标高，计算出桩顶设计标高与护筒口高差，加工吊筋长度，吊筋与主筋采用对接连接，吊筋与护筒口采用U型卡口连接固定，钢筋笼安装完成后进行导管安装。
B、二次清孔采用泥浆正循环方法进行清孔,在总平面布置图指定场地开挖沉淀池、泥浆池，因本地地质情况，钻孔时浆液可用为泥浆，在二次清孔时采用3PN泵向混凝土导管内进行泥浆清洗时间不少于20分钟。
C、 混凝土导管的实际下放长度作为实际孔深，二次清孔完毕后立即采用测绳测设孔深，二者差值判断沉渣厚度是否符合设计要求，最后砼灌注前的沉渣厚度小于5cm。

(8) dipping steel cage, placed catheter, secondary Chiang Khong
A, all of the drilling piles were reinforced steel cage inside the processing forming process. Lifting frame using the rig is complete, effective length less than 12 meters directly under the cages, effective length 12 m above the wellhead once docked. When lifting the steel cage center should coincide with the center hole, using reinforced concrete protective layer round cake, pie radius design protective layer thickness (75mm); the number of arranged according to specifications of each pad section steel cage should be at least two groups, each set of three, should be evenly distributed on the same section, a single reinforcement cage length greater than 12m, it should be added to a group. To ensure that the steel cage position in the hole. Then dipping steel cage bottom casing near the mouth, revealing the orifice is about one meter across with steel reinforcement cage stand on the casing mouth, remains fixed, then hoisting Section steel cage, the cage, and the cage bottom should be perpendicular to the center line ,coincide. After the pairing is complete by the owners and supervision of a professional engineer acceptance, under the reinforcement cage pile top elevation design elevation. With Level ferreted out casing opening level is calculated top of the pile design elevation and Casings port elevation, processing and hanging bars length, hanging bars and reinforcement of butt connections, hanging bars and Casings opening U-shaped bayonet fixed, steel cage installation catheter after installation is complete.
B, the second hole cleaning method using the positive cycle of mud hole cleaning, designated excavation sedimentation in total floorplan, mud pools, due to the local geological conditions, drilling mud slurry is available, when using secondary Chiang Khong 3PN pump catheter into the concrete slurry cleaning time less than 20 minutes.
C, the actual length of the decentralization of concrete pipe as the actual depth of the hole, measuring rope used immediately after the second survey bore deep hole cleaning is completed, the difference between the two is determined sediment thickness meets the design requirements, sediment thickness is less than before the final concrete casting 5cm.
