传统混凝土检测多采用钻孔取芯检测等手段,相对而言施工检测效率不高,且偶然性因素大,施工不方便。为此,根据锦屏二级水电站3#、4#引水隧洞施工中,利用TCRA1201全站仪进行喷射混凝土厚度检测的施工实践,提出利用全站仪进行隧洞衬砌喷射混凝土厚度检测的一种新方法。

The core-drilling method is often taken in the traditional detection on concrete with the deficiencies of lower detection efficiency,larger contingency and inconvenience of the construction concerned.Therefore,a new method for the detection on the thickness of the jetcrete for the tunnel lining with total station is put forward herein based on the construction practice of the application of TCRA1201 Total Station to detection on the jetcrete thickness during the construction of the No.3 and No.4 water diversion tunnels of Jinping Hydropower Station Ⅱ.
