FOUNDATION STRUCTURE OF STRUCTURE, FOUNDATION CONSTRUCTION METHOD, AND SUPPORT PIPE MATERIAL USED FOR FOUNDATION
To provide a foundation structure of a structure, a foundation construction method, and a support pipe material used for a foundation, which can support the structure having a support pillar by high vertical and horizontal support forces.SOLUTION: A foundation structure 1 comprises: a columnar improvement body 10; a support pipe material 20 buried in the columnar improvement body 10; a support pillar 30 erected on a support plate 22; foundation concrete 41 installed between at least an inner surface of a pipe body 21 and an outer surface of the support pillar 30; and root wrapping concrete 42 installed between an upper part of the columnar improvement body 10 and a ground surface. The foundation construction method includes a drilling step S1, a columnar improving step S2, a pitching step S3, an erecting step S4, and an installation step S5. The support pipe material 20 includes the pipe body 21, the support plate 22 shielding the inside of a pipe of the pipe body 21 in a crossing direction, an air hole 23 disposed at a peripheral edge of the support plate 22, and an air pipe 24 communicated with the air hole 23. The air pipe 24 is composed of an angle material, a channel material or a half-split pipe installed along the inner surface of the pipe body 21.SELECTED DRAWING: Figure 1
【課題】支柱を有する構造物を、高い鉛直支持力と水平支持力で支持可能な、構造物の基礎構造、基礎の施工方法、及び基礎に用いる支持管材を提供すること。【解決手段】本発明の基礎構造１は、柱状改良体１０と、柱状改良体１０内に埋入した支持管材２０と、支持板２２上に立設した支柱３０と、少なくとも管本体２１の内面と支柱３０の外面の間に設置した基礎コンクリート４１と、柱状改良体１０の上部と地表面との間に設置した根巻きコンクリート４２と、を備えることを特徴とする。本発明の基礎の施工方法は、削孔工程Ｓ１と、柱状改良工程Ｓ２と、建込み工程Ｓ３と、立設工程Ｓ４と、打設工程Ｓ５と、を備えることを特徴とする。本発明の支持管材２０は、管本体２１と、管本体２１の管内を横断方向に遮蔽した支持板２２と、支持板２２の周縁に配置した抜気孔２３と、抜気孔２３と連通する抜気管２４と、を備え、抜気管２４を管本体２１の内面に沿って付設した、アングル材、チャンネル材、又は半割り管によって構成したことを特徴とする。【選択図】図１
