In mountain tunneling, in order to applying mechanical function to tunnel lining, reinforcing bars are constructed in tunnel lining at mine mouth or small soil cover section, etc. Joint steel bars are used to fix reinforcing bars. Survey of the installation and cutting positions of joint steel bars by a total station have some problems such as time-consuming and requires more manpower. In order to solve these problems, we are developing a newly installation system of joint steel bars using projection mapping technology. We report the outline of this system and the field test result.
