STRUCTURE OF COMPOSITE UNDERGROUND CONTINUOUS WALL, AND CONSTRUCTION METHOD OF COMPOSITE UNDERGROUND CONTINUOUS WALL
PROBLEM TO BE SOLVED: To provide a composite underground continuous wall and a construction method for the composite underground continuous wall that may be configured readily over an underground obstacle, by supporting a ground improvement section having low bending strength by bearing pressure with a structure having high bending strength.SOLUTION: A second underground continuous wall 5 having high bending strength is constructed continuously from a first underground continuous wall 3, beside an underground obstacle 11 to a prescribed depth 27 from a construction base surface 21. Furthermore, a ground improvement section 7 is constructed to come in contact with a side surface 24 of the underground continuous wall 5, in a range to the prescribed depth 27. The underground continuous wall 5 includes an overhung part 9 that projects toward the ground improvement section 7. The overhung part 9 integrates the underground continuous wall 5 with the ground improvement section 7, thus constructing a composite underground continuous wall 1. With the composite underground continuous wall 1, the overhung part 9 of the underground continuous wall 5 receives earth pressure from a rear surface side 17, and the ground improvement section 7 is supported the overhung part 9 bearing the pressure.SELECTED DRAWING: Figure 1
【課題】曲げ耐力を有する構造物の支圧で曲げ耐力のない地盤改良部を支持することにより、地中支障物を跨いで容易に形成することができる複合地中連続壁の構造および複合地中連続壁の構築方法を提供すること。【解決手段】第１の地中連続壁３に連続するように、地中支障物１１の側方に、施工基面２１から所定の深さ２７まで、曲げ耐力を有する第２の地中連続壁５を施工する。また、地中連続壁５の側面２４に接するように、所定の深さ２７までの範囲に地盤改良部７を施工する。地中連続壁５は、地盤改良部７の方向に張出す張出し部９を有し、張出し部９によって地中連続壁５と地盤改良部７とが一体化され、複合地中連続壁５が構築される。複合地中連続壁１では、背面側１７からの土圧を地中連続壁５の張出し部９が受け、張出し部９の支圧で地盤改良部７が支持される。【選択図】図１
