PURPOSE: A double packer for pressure grouting and a slope reinforcing method using the same are provided to reduce assembling and dismantling work times by changing the pressing structure and material of a pressure packer used in a slope reinforcing construction and an underground excavation construction. CONSTITUTION: A double packer for pressure grouting is composed of a reinforcement insertion pipe(10), an upward compression plate(20), an expandable rubber packer(30), a downward compression plate(40), and an expandable air packer(50). The reinforcement insertion pipe has constant diameter and constant length. The upward compression plate has constant thickness and constant diameter. The rubber packer has the regular interval from the upward compression plate. The rubber packer is assembled to the outer circumference of the reinforcement insertion pipe. The downward compression plate has the regular interval from the expandable rubber packer. The expandable air packer has the regular interval from the downward compression plate. |
