PURPOSE: A multi-tube chemical liquid injection device for injecting silica sol grouting solution into the ground and a chemical grouting method using the same are provided to reinforce the ground by injecting silica sol grouting solution into weak soil foundation with high permeability including sandy soil or alluvium. CONSTITUTION: A multi-tube chemical liquid injection device for injecting silica sol grouting solution into the ground comprises a swivel, an injection material transfer pipe extension assembly and an extension coupling member(300). The injection material transfer pipe extension assembly comprises an injection valve. The injection valve injects a grout injection material to the ground inside. The grout material transfer pipe extension assembly interlinks the swivel and injection material transfer pipe extension assembly. The extension coupling member interlinks the grout material transfer pipe extension assembly to the swivel and the injection material transfer pipe extension assembly. The extension coupling member consecutively interlinks the connected transfer pipe extension assemblies.
