Sliding up shuttering technology is that once install the shuttering and continue pouring to form to insure the accomplishment of high quality cylinder silo construction. It can make the inner and outer wall smooth without any shuttering connection mark and make the outer wall get the effect of rinsing slip forming. 1) 全部用GYD60大吨位千斤顶、482.75钢管作滑模支承杆。All slip forming support poles will use large tonnage jack and 482.75steel tube.2) 简化滑模平台，实际只设人行通道，即减轻平台荷载又方便施工。It should simplified slip forming platform. Actually just set up a walking passage, which will reduce platform load as well as keep facility of construction 3) 柔性模板接缝之间夹一条海棉条，可以有效地防止板缝漏浆，同时使板缝拼接平整、圆滑，提高筒仓结构滑模的外观质量There is one piece sponge in the joint of flexible shuttering, which can effectively prevent leakage from the joint and at same time keep the joint flat, smooth to improve the appearance of the cylinder silo structure slip forming 4) 滑模工程外观不好的另一主要原因是水泥浆沿筒壁流淌，为防止操作平台上水泥的流淌，在模板下口和模板间用6夹海绵条吸附水泥浆，操作人员在每层及时清理海绵内的水泥浆。Another reason for slip forming appearance drawback is that grout flow along cylinder wall. In order to stop the grout from control platform, use 6 sponge between shuttering below gob and shuttering to absorb grout. Controllers should clear up the group from sponge in each layer in time 5) 出模混凝土的处理措施：对出模混凝土及时进行原浆压光和对流淌水泥浆进行铲除，在吊架上环绕筒壁设一圈20铸铁管，在管上靠筒壁一侧均匀钻孔，用管道泵将水压入铸铁管，随滑模施工对筒壁混凝土进行喷淋。并派专人用清水均匀涂刷筒壁，最终达到表面圆滑、光洁、色泽基本一致的效果，同时在内外筒壁刷混凝土养护液养生。Disposal measure of out shuttering concrete: press the out shuttering concrete to smooth in time and remove the flowing grout. On the scaffolding set a 20 cast iron tube around cylinder wall, drill equal holes on the tube next to cylinder wall, use tube pump compress water into cast iron tube, and then water can be sprayed to the concrete on cylinder wall during slip forming construction. Also special man should be arranged to brush the cylinder wall smoothly with clean water. Finally consistent effect of surface smooth, color and lustre will achieve. At the same time brush concrete maintenance liquid on inside and outside cylinder wall to maintain三、生料库滑模施工Raw meal silo slip forming construction1滑模工艺设计Design of slip forming technics根据图纸设计，生料库为预应力钢筋砼结构，外筒高 m，内径为 m，壁厚 m以下为 mm，以上为 mm，内筒高 m，内径为 m，壁厚为 mm，外筒每米砼量约为 m3，内筒每米砼量约为 m3，为保证砼的输送，在库外设一台塔吊和两台布料车进行施工。According to drawing design, raw mill silo is pre-stress bar concrete structure.

Concrete quantity per meter of out cylinder is m3, Concrete quantity per meter of inner cylinder is m3 In order to keep concrete transport, 1 tower crane and 2 material trucks prepared out of the silo for construction. 外筒筒壁从基础顶标高开始采用滑模施工，滑至标高10.8m处，空滑至13.6m标高，施工内筒及减压锥底板。待减压锥底板施工完毕后改装滑模平台滑至77.2m。Out cylinder wall begins slip forming construction from foundation top elevation. After slide to 10.8m elevation, slide with empty concrete to 13.6m elevation where reach the construction inner cylinder and decompress cone bottom board. After decompress cone bottom board construction finish, refit the slip forming platform and slide to 77.2m 2.外筒滑模平台设计design of out cylinder slip forming platform1）筒壁布置提升架和千斤顶，平台构件布置见平面布置图。Set hoist frame and jack beside cylinder wall.

Different type structure of slip forming project, its oil route disposal is different. While the location of the jack is fixed with the disposal of hoist frame 本工程拟采用三级分组并联油路布置，一级主油管选用19mm高压耐油橡胶管，二级分油管选用13mm高压耐油橡胶软管，支油管选用10mm高压软管伸向各千斤顶；分油器采用无缝钢管制作。一级分油器，一进六出（根据建筑平面每一方各一条分油路）；二级分油器一进三出，各主油管长度和直径均取其相等，并作环形布置有利于均衡滑升；三级分油器一进六出通向各千斤顶，每级、每组均设有截流阀加以控制，千斤顶单独设针形阀，这样方便纠编和抽拔支承杆。This project is planning to adopt 3 class groups and parallel connection of oil disposal. The first class main oil pipe will choose 19mm high pressure and oil endurance rubber pipe. The second class separate oil pipe will choose 13mm high pressure and oil endurance rubber pipe. Branch oil pipe will choose 10mm high pressure tube to run out to each jacks. Oil separator will adopt seamless steel pipe for manufacture. The first class oil separator will come out 6 parts after 1 enter (according to construction plane, each side should have one oil route). The second oil separator will come out 3 parts after 1 enter. Length and diameter of each main pipe are all selected the same. And rounding disposal will be used in favor of equilibrium sliding up. The third oil separator will come out 6 parts after 1enter to each jack. Every class and every group will dispose a shutting valve to control. Jacks will separately use needle valve, which be convenient to rectify and pull out the supporting pole.四、库壁结构滑升施工工艺Silo wall structure elevating construction technical1. 滑升区段的划分Elevation section division根据经济和可行的原则考虑，从基础顶标高开始的竖向结构采用滑模工艺施工。Think of the economic and feasible principle, from the foundation top the vertical structure adopt slip forming technology to construct2. 滑模平台组装Slip forming platform installation滑模平台结构详见滑模平台布置图。Slip forming platform structure see “slip formin
