一、前言回转上升式自动模板(Auto-Setting-Form for Dam,简称ASFOD)是国外近几年开发的一种新型模板,适用于水库、堤堰、大坝等具有平整外表面的中、大型砼工程。这类构筑物通常多采用起重机吊升的滑升模板来浇灌造型,往往将作业平台和模板制成一体形成滑模组合结构,施工人员须随模板上升移动,并在平台上装卸模板的锚定螺栓,浇灌中有时还须在数十米高的平台上停留等待,以便浇灌完毕进行下一次的螺栓装卸工作。回转上升式自动模板出现后避免了这种繁重的高空作业,使操作安全
I. INTRODUCTION Auto-Setting-Form for Dam (abbreviated as ASFOD) is a new type of template developed in foreign countries in recent years. It is suitable for medium and large scales with smooth outer surfaces such as reservoirs, embankments, and dams. engineering. This type of structure is usually constructed by using a lifting template that is lifted by a crane to form a sliding pattern. The working platform and the formwork are often integrated to form a slipform assembly structure. The construction personnel must move up with the template and load and unload the template’s anchor bolts on the platform. In watering, it is sometimes necessary to wait and rest on platforms that are several tens of meters in height so that the watering can be completed for the next bolting work. The slewing ascending type automatic template avoids this kind of heavy aerial work and makes the operation safe
