【摘要】 文章针对既有的隧道防水层铺设工艺存在的问题,提出了基于水密塑料组件的隧道防水层铺设方法(简称LV法)。LV法的每套塑料组件由外凸件、扣压件和封堵头组成。运用LV法固定防水层有三个步骤:(1)在普通防水板的适当位置开孔并组装外凸件和扣压件;(2)用钢钉通过外凸件的预留钉孔将防水板固定于喷混凝土基面;(3)用封堵头逐个封堵外凸件的钉尾。为了证明塑料组件设置部位的水密性,对LV组件进行了防水性能试验。更多还原

【Abstract】 In order to solve the current technique problems regarding the pavement of the waterproof layer in tunnels, a watertight plastic component-based method for the laying of the waterproof layer(LV for short) was developed.The plastic component consists of a convex part,a fastening part and a plugging part.There are three steps to fix the waterproof layer by the LV method:(1) punch the waterproof plate in the proper position and assemble the convex part and fastening part,(2) fix the waterproof plate on the sprayed concrete plane using steel nails through the predesigned circular hole of the convex part,and(3) plug the nail tail of convex part.An experiment for testing the watertightness of LV components was performed.更多还原
