EXPANSION APPARATUS USING PACKER

摘要

PURPOSE: A tip-end picketer-embedded expansion body using an expansion packer is provided to carry out construction without noise or vibration and measure support force from relation between the displacement and tension. CONSTITUTION: A tip-end picketer-embedded expansion body using an expansion packer comprises a packer, a tip-end expansion body(20), an upper guide plate(40), and a lower guide plate(50). A packer is made of elastic materials and has an extension part in which an injection port is formed on the top thereof. The tip-end expansion body is installed to surround the outer surface of the packer. A hollow part is filled with steel or concrete inside. Multiple insertion holes are formed on one side of the tip-end expansion body and a projection is formed on the other side. The upper guide plate is installed on the top of the tip-end expansion body. A penetration part is formed at the center of the upper guide plate and multiple guide projections are formed on the lower surface of the upper guide plate.
