PURPOSE: An auxiliary device to bond a concrete block is provided to reduce the term of works and to maintain the concrete block to be firmly bonded, so that the stability of a structure is improved. CONSTITUTION: An auxiliary device(20) consists of a reinforcement net(21) and an injection pipe(22). The reinforcement net is made by crossing bars, and installed between the ground and a concrete block(10). The injection pipe is formed in hollow pipe shape, and inserted into an injection hole(11) for back-filling. Several grooves are formed in the injection pipe along the length, and connected to the inside of the injection pipe. One end of the injection pipe is fixed at the center of the reinforcement net and is projected forward. Therefore, when concrete is poured through the injection pipe, concrete is supplied into the space between the ground and the concrete block through the groove.
