FEEDING DEVICE OF AGENT FOR MULTI-STEPPED REINFORCING FOUNDATION

摘要

PURPOSE: A simultaneous multistage ground reinforcement material injection system is provided to reduce injection time by enabling simultaneous injection with uniform pressure. CONSTITUTION: A simultaneous multistage ground reinforcement material injection system comprises an injection inner tube(10) and packer parts(20). The injection inner tube has an injection port(12) and multiple discharge ports(14). The injection port is formed in a separated U-shape. The discharge ports discharge a ground reinforcement material(R) injected through the injection port. The packer parts are formed in the injection inner tube at uniform intervals. Each packer part is composed of a packer body(22) and a rubber packer(24). The packer bodies cover the injection inner tube. The rubber packers are expandably formed on the top of the packer bodies.
