[0002] In infrastructure such as subways and high-speed railways, water supply and drainage and electrical systems need to be installed along both sides of the tunnel. The installation of the water supply and drainage system includes two parts: pipe support installation and pipe laying. The pipe support installation involves the wall drilling process, and the electrical system involves the lighting installation process.
