Limestone warehouse project slip form structure and special construction scheme thereof
The invention relates to a limestone warehouse project slip form special construction scheme. The special construction scheme comprises the following steps that 1) preparation work is conducted before slip form construction, specifically, sundries are removed, positioning marking is carried out, and equipment conditions are inspected; (2) an operation platform and a sliding lifting device are assembled, specifically, a central drum ring, a lifting frame, a radiation beam and a pull rod are sequentially assembled, then a formwork is installed, and then a hydraulic system and an electric power system are installed; and (3) cylinder body sliding and lifting are conducted, pouring is conducted during initial sliding and lifting, pouring objects are solidified, lifting is conducted by 1-2 strokes, the sliding and lifting speed is V = (H-h-a)/t, inner and outer hanging foot stands are installed, an outer side fence is installed, a safety net is hung, and then sliding and lifting are conducted circularly till the project is completed. According to the limestone warehouse project slip form structure and the special construction scheme thereof, by conducting cleaning inspection and refining the detailed rules of the scheme, slurry leakage of the formwork can be prevented, the phenomenon that slurry is hung on the outer wall of the cylinder body is avoided, the situation that the concrete is cracked due to the fact that the friction resistance of the concrete to the formwork is too large can be prevented, and slip form construction is safer and more reliable.
本发明涉及石灰石库工程滑模专项施工方案，包括以下步骤：1)滑膜施工前准备工作：清除杂物、进行定位标记、检验设备情况；2)操作平台及滑升装置组装：依次组装中心鼓圈、提升架、辐射梁和拉杆，再将模板进行安装，再安装液压系统及电力系统；3)筒身滑升：初步滑升时进行浇注，待浇注物固化，提升1‑2个行程，滑升速度依据为V＝(H‑h‑a)/t，安装内、外吊脚架，在安装外侧围栏及悬挂安全网，随后循环滑升，直至工程完成。该石灰石库工程滑模结构及其专项施工方案，通过进行清理检验，细化方案细则，可防止模板漏浆，避免筒身外壁出现挂浆现象，且可防止砼对模板摩擦阻力过大而拉裂砼，使滑模施工更加安全可靠。
