| 摘要 |
The present invention relates to a boring machine for ground reinforcement comprising the front end device of a quadruple pipe and a ground reinforcement method using the same, which is capable of being equipped with the quadruple pipe and one front end device thereof to reduce weight, thereby preventing the boring machine for ground reinforcement from falling on the ground, spraying, through the front end device of the quadruple pipe, air, cutting water, quick setting reactants, a hardener, or mortar to reduce time required for ground reinforcement work. On the outer surface of the front device of the quadruple pipe, a first horizontal nozzle is horizontally connected to an air passage pipe and a cutting water passage pipe to horizontally spray air and cutting water, a lower nozzle is connected to the air passage pipe and the cutting water passage pipe at a constant interval from the first horizontal nozzle to be sloped downwardly to spray air and cutting water downwardly, an upper nozzle is connected to the air passage pipe and the cutting water passage pipe at a constant interval from the first horizontal nozzle to be sloped upwardly to spray air and cutting water upwardly, a second horizontal nozzle is horizontally connected to a hardener or mortar passage pipe and a quick setting reactant passage pipe to horizontally spray a hardener or mortar and quick setting reactants, and a third horizontal nozzle is collinearly positioned at a constant interval from the second horizontal nozzle and connected to the hardener or mortar passage pipe and the quick setting reactant passage pipe to horizontally spray a hardener or mortar and quick setting reactants. |
