日本学者在“日本隧洞衬砌方法”的论文中指出,近十多年采用的以喷混凝土为主的支护方法存在一系列问题。如在喷射过程中会污染工作环境,因材料回弹而造成浪费等。为了解决这些问题,提出三种新的衬砌方法。其基本原理是:使用一种特殊的移动式模板,在开挖面与模板之间浇筑混凝土,沿着圆周 Japanese scholars in the “Japanese Tunnel Lining Method,” the paper pointed out that the past ten years using spray-based concrete support method has a series of problems. As in the spraying process will pollute the working environment, resulting in material waste due to rebound. In order to solve these problems, three new lining methods are proposed. The basic principle is: Use a special type of mobile template, pouring concrete between the excavation surface and the template, along the circumference
