Large-diameter silo unbonded prestressed steel strand mounting process for slip-form construction
The invention discloses an unbonded prestressed steel strand mounting process for a large-diameter silo in slip-form construction, and relates to the technical field of unbonded prestressed steel strand mounting. The method comprises the following steps that firstly, a tensioning end anchor bearing plate and a spiral bar are fixed to the position of a buttress according to the design requirement; the method has the advantages that the prestressed tendons are processed by manufacturers in a fixed-length manner, and are bound and transported one by one, so that the occupied site of a construction site is saved, and the site blanking period and the labor cost are saved; the tensioning end anchor backing plate adopts a wrought iron cluster large anchor backing plate, and through holes corresponding to the prestressed steel strands in number are formed in the anchor backing plate; a through hole is formed in the cavity mold, positioning is completed by directly penetrating a steel strand into the through hole, a conventional wood or iron cavity mold is replaced, the construction efficiency is improved, the strand pulling machine is installed at the position of a buttress, the strand pulling guide pipe is matched with the strand pulling machine, strand pulling is conducted mechanically, only three persons need to be configured for each section, and the threading process is supervised and guided. The labor intensity of workers is reduced.
本发明公开了一种滑模施工的大直径筒仓无粘结预应力钢绞线安装工艺，涉及无粘结预应力钢绞线安装技术领域。本发明包括以下步骤：步骤一：将张拉端部锚垫板、螺旋筋按设计要求固定在扶壁柱的位置。本发明的优点在于：预应力筋为厂家定尺加工，且1根1盘盘、绑扎运输，节约施工现场场地占用，节省现场下料工期及用工费用；张拉端锚垫板采用熟铁集束大锚垫板，锚垫板上有对应预应力钢绞线根数的通孔；穴模上设置有通孔，直接向通孔内部穿入钢绞线就完成定位，替代常规用的木质或铁质穴模，提高施工效率，穿束机安装在扶壁柱的位置，穿束导管和穿束机配合，采用机械进行穿束，每段仅需配置3人，对穿线过程进行监督、引导即可，降低工人劳动强度。
