SUBSTRUCTURE OF LONG OBJECT AND CONSTRUCTION METHOD FOR SUBSTRUCTURE OF LONG OBJECT
PROBLEM TO BE SOLVED: To provide a substructure that can be constructed by a relatively small construction and facilitates securing the verticality of a strut, and its construction method.SOLUTION: A substructure includes: a foundation outer pipe 1 formed by embedding a steel pipe of a sufficient length in the ground while an axis line is assumed as a vertical direction, in an improved ground G formed by improving the ground; an intra-pipe foundation part 5 with a top surface formed in an appropriate depth in the inside of the foundation outer pipe by a portion of the improved ground; a plurality of positioning protrusions 4 with the protrusion length adjustably provided in an upper end vicinity of the foundation outer pipe while projecting inside; and filling materials placed in the gap between a long object P and the basic outer pipe. A surface 20a of a foundation bottom plate 2 is horizontally maintained in the upper part of the intra-pipe foundation part, and a filler 6 is filled between the intra-pipe foundation part and a foundation bottom plate to fix the foundation bottom plate, and is supported while bringing the lower end (lower edge) P1 of a strut P into contact with the surface.
【課題】 比較的小規模な工事によって構築できるとともに、支柱の鉛直性を容易に確保し得る基礎構造と、その工事方法を提供する。【解決手段】 地盤が改良されて形成された改良地盤Ｇに、十分な長さの鋼管が軸線を鉛直方向としつつ地中に埋設されてなる基礎外管１と、改良地盤の一部によって、基礎外管の内部における適宜な深度に上部表面が形成される管内基礎部５と、基礎外管の上端近傍において内側に突出しつつ突出長を調整可能に設けられた複数の位置決め突起４と、長尺物Ｐと基礎外管との間隙に打設される間詰材料とで構成される。管内基礎部の上方に基礎底板２の表面２０ａを水平に維持するとともに、管内基礎部と基礎底板の間に充填剤６を充填して基礎底板を固定し、その表面に支柱Ｐの下端（下端縁）Ｐ１を当接しつつ支持する。【選択図】 図２
