Before hanging a preassembled reinforcement cage 5 into the excavated groove 2, a form 6 is installed on the preassembled reinforcement cage 5 via spacers 7, and the preassembled reinforcement cage 5 having the form 6 installed thereon is hung into the excavated groove 2, followed by pouring concrete 11.
