THE DEEPENED SHEET PLATE MADE OF AN IRON REINFORCING ROD AND THE METHOD OF INSTALLATION

摘要

PURPOSE: An installation method of a reinforced concrete structure having retaining walls is provided to reduce material costs by minimizing the amount of required steel materials and to prevent underground water from flowing into a reinforced concrete structure. CONSTITUTION: An installation method of a reinforced concrete structure having earth retaining walls is as follows. A first row of H-shaped steels(11) and a second row of H-shaped steels(12) are welded to each other through coupling stiffeners. An excavation area(1) surrounded by the first row of steel plates is excavated. After the excavation, the first row of steel plates is removed. Soil between the first row of steel plates and the second row of steel plates is removed. Steel plates(21) are re-inserted into the gaps between first coupling guides welded to the inside the first row of H-shaped steels. Reinforcement structures are inserted between the re-inserted steel plates, and concrete is placed and cured to construct a permanent retaining wall. The H-shaped steels and the steel plates are removed.
