“逆作法”施工工艺是目前高层建筑施工中使用的一种新型工艺方法。其工艺顺序是采用由上至下,先形成土钉墙、桩柱、预应力锚索混合支护体系支护和受力支撑后施工内部主体,先顶板施工后底板施工。文章结合工程实例,对“逆作法”施工工艺的在人防工程中的应用进行了具体的介绍,并在工期、费用、空间利用率等方面总结了应用的效果。
“Reverse method ” Construction technology is currently a new type of process used in the construction of high-rise buildings. The process order is from top to bottom, first to form a soil nailing wall, pile, prestressed anchor cable support system and the force of the support after the construction of the main body, the first roof construction after the floor construction. In this paper, the application of “reverse method” construction technology in civil air defense project is introduced in detail in combination with engineering examples, and the application effect is summarized in terms of construction period, cost and space utilization.
