二、筒体结构滑模施工技术方案
Cylinder slip forming construction technical plan
筒仓结构系按滑升模板工艺设计，滑升模板工艺系一次组装模板，连续浇灌成形，确保高质量地完成本工程的筒仓施工，做到内外壁圆滑无模板接痕，外壁做到清水滑模效果。
Cylinder silo structure is designed according to sliding up shuttering technology. 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GYD－60大吨位千斤顶、Φ48×2.75钢管作滑模支承杆。
All slip forming support poles will use large tonnage jack and Φ48×2.75steel 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Ф6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 Ф6 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Ф20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 Ф20 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 construction 1．滑模工艺设计Design of slip forming technics

千斤顶的油路布置原则,应使千斤顶尽可能地同步工作,达到压力传递均匀，方便控制和纠偏的目的。不同结构类别的滑模工程，其油路布置是不一样的。而千斤顶位置随
着提升架的布置而确定。
Principle of jack oil route disposal is that taking every means to make jacks work synchronize, so that pressure can be delivered equally and reach the aim of convenient to control and rectify. 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.

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 construct
2. 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 forming platform disposal drawing”
首先按滑模平台结构设计要求将结构加工完后，对各部件单元进行试组装，然后运至
现场，在基础顶标高处进行组装，严格控制组装时的测平和轴线的准确位置和垂直度。组装前应先绑扎1200㎜高的钢筋，以上的钢筋和钢绞线为边滑边绑扎。
First finish the structure manufacture according to slip forming platform structure design requirement. And try installing each unit parts. Then transport to site, and install them on the foundation top elevation part. When installing, strictly control the level testing and axes line’s exact position and vertical degree. Before installation 1200mm height reinforcing steel bar should be tied. The above reinforcing steel bar and bar tendon are sliding as well as tying.
3. 组装顺序Installation sequence

One pouring layer's slip forming construction technical flow
筒壁竖筋绑扎时,相邻钢筋接头应设计图纸及规范错开,且同一水平截面接头数不超过竖筋总数的25%。水平环筋和钢绞线随滑升速度分层绑扎，必须严格按设计要求进行焊接，每相邻接头至少相隔3层环筋。内外层钢筋有“∽”形拉结筋定位，按设计要求梅花形布置。混凝土分层浇灌，每层高度20--30cm，筒体预埋件、预留孔随滑升速度与绑扎钢筋同时进行埋设和预留。滑模千斤顶支承杆接头采用双绑条单面焊。出模砼内外筒壁采用原桨压光，外壁要求达到清水模板效果，终凝后浇水养护。 When tying reinforcing steel bar to cylinder wall, near by steel bars’ connection part should be deviate from designed drawing and regulation. And the number of connection part on the same horizontal section is not over 25% of the total steel bars’ number. Horizontal rounding reinforcing steel bar and bar tendon will tie layer by layer according to sliding up speed. It must be strictly follow the design requirement to weld, and every near by connection part should be apart at least 3 layer rounding reinforcing steel bar. Inside and outside layer the reinforcing steel bar have “∽” type pulling reinforcing steel bar to fix the location. And make a cinquefoil disposal according to design requirement. Concrete should be poured layer by layer. And each layer is 20-30cm high. Embedded cylinder body and retained holes will be embedded and retained as sliding up speed and reinforcing steel bar tying

绑扎钢筋和钢绞线，焊接支承杆→浇砼20--30cm→滑升→垂直观测纠偏纠扭→铁件预埋、孔洞预留→找平、移限位卡→出模混凝土加原浆压光，在达到一定强度后用清水涂刷。Tying reinforcing steel bar and bar tendon, weld supporting pole→pouring concrete20—30cm→sliding up→vertical observation for rectifying deviation and wrest→embedding iron piece, retaining holes→checking for flat, moving limit wedge→adding original slurry to press and polish after concrete out of shuttering, and use
clean water to brush when it is reaching a certain intensity. 6．始滑first slip
内外模组装好，经反复核查无误后，清除模板内杂物即可扎始滑段的水平筋和固定埋件，对施工缝进行处理，油路、电气、砼输送系统均正常运转达后，方可浇灌砼。始滑第一层砼浇筑厚度30cm，滑升两个行程（5cm）；再浇30cm，再滑升5cm，再浇30cm，即完成始滑过程而转入正常滑升。
After inside and outside shuttering installation finish and well check to find no mistake, clear up the rubbish inside the shuttering and then horizontal reinforcing steel bar can be tied on slip commencement section and embedded piece can be fix, and construction seam can be disposed. After Oil rount, electric and concrete transport system are all well working, then concrete pouring can be started. During first slip, concrete pouring thickness of first layer is 30cm, and after sliding up 2 times (5cm), pouring another 30cm, and then sliding up another 5cm, after pouring 30cm once more, and then first slip finish and change to usuall sliding up.
7．钢筋和钢绞线绑扎Reinforcing steel bars and bars tendon colligation
钢筋在地面制作好后，分批由塔吊运至滑模平台上，为配合滑模快速施工的需要，竖向钢筋采用绑扎搭接接头；均匀、排列有次，检测允许偏差必须达优良标准。竖筋按6m（1/2成品钢筋长度）分段，环筋12m（成品钢筋长度）分段，竖筋、环筋接头错开率均为1/4。
After reinforcing steel bars are finished manufacture on the ground, they will be partly taken to slip forming platform by tower crane. In order to cooperate slip forming fast construction, vertical reinforcing steel bar will adopt tying joint connection part. Equilibriums, arranged in order and check that allowed deviation must achieve good standard. Vertical reinforcing steel bar divided in every 6m (it is 1/2 length of finished reinforcing steel bar). Rounding reinforcing steel bar divided in every 12m (the length of finished reinforcing steel bar). All deviation rate of vertical and rounding reinforcing steel bar are 1/4
钢绞线在地面制作好后，分批由塔吊运至滑模平台上，先确定钢绞线的位置，焊接钢绞线托架，穿钢绞线并安装埋设预应力锚板。
After bar tendon are finished on the ground, they will be partly taken to slip forming platform by tower crane. First fix the location of bar tendon, weld bar tendon supporter, and then go through bar tendon and set up embedded pre-stress anchor board.
支承杆一律采用为Ф48×3.5钢管，全部采用焊接，支承杆的接头，在同一截面内按25%均匀布置，支承杆的标准长度定为6m，在开始时初始长度分别为1.5m、3m、4.5m、6m，各占1/4，依次排列，以后均按标准长度接长，接头接好后用砂轮打磨光滑，待千斤顶过后加焊钢筋帮条。第一段支承杆插入千斤顶后，不要落在混凝土面上，预留50cm，待试滑时，再插到位。
Supporting poles will be all usingФ48×3.5 type steel tube and all welding. Connecting part of supporting poles will be 25% equally dispose on the same section. Standard length of supporting pole is 6m. at the beginning, each preliminary length are separately 1.5m, 3m, 4.5m, 6m, while each one takes 1/4. they will be arranged one by one, and after that standard length will be used. After connecting parts are well connected, they will be polished by grinding. And after jack, weld supporting reinforcing steel bar. After first part supporting pole insert the jack, it should not be dropped on the concrete. Retain 50cm and insert it to the right location when trying slipping.
施工时应注意把筒壁的双排主筋和钢绞线绑扎好，并把处于其中立筋扶正。为了做好这一工作可采用钢筋导板或钢筋梳子定位。钢筋导板的做法是用50×100mm的方木沿筒壁宽度两侧布置，固定的提升架上，方木上钉有短板，短板上钻有按主筋间距布置的圆孔，主筋通过圆孔插放。这样即保证了细长主筋的稳定，也保证了钢筋的准确位置，同时洞口也可通过木枋进行固定。
When construction attention should be take on the two line main reinforcing steel bar and bar tendon tying. And make the vertical reinforcing steel bar straight among them. In order to well finish this job, reinforcing steel bar plank and comb can be used to fix the location. Method of making reinforcing steel bar plank is to dispose 50×100mm wood pieces along cylinder wall two width side. On fixed hoist frame and wood pieces, there will be some short board.
