Application manner null of panel structure and underground external wall for underground external wall

摘要

NEW MATERIAL:To exhibit sufficient yield strength and reduce the cost and to shorten the construction period by arranging a set of H-beams lengthwise of excavated holes at specific intervals, and constructing steel plate materials between flanges of the H-beams. CONSTITUTION:Excavated holes 12... filled with self-curing stabilizing liquids 14... are so formed that the object ground are surrounded by them. After that, a set of H-beams 16... are so arranged at specific intervals that they are disposed lengthwise of the excavated holes 12..., and steel plate materials 18... are constructed between flanges of the H-beams 16... to form underground external wall panels 20 and 20. Then, the underground external wall panels 20 and 20 are inserted into the excavated holes 12..., and the inside of the object ground surrounded by the underground external wall panels 20 and 20 is excavated. Then, structural materials arranged to the inside of the object ground and the underground external wall panels 20 and 20 are joined to construct the underground external wall.
