LID BODY FOR UNDERGROUND EMBEDDED STEEL PIPE, UNDERGROUND EMBEDDED STEEL PIPE, AND JOINT MEMBER
To provide a lid body for underground embedded steel pipes that can cover an opening on the tip surface of a steel pipe in an embedded direction by using a simple structure, and for which heat deformation is unlikely to occur with the lid body that covers the tip of a steel pipe.SOLUTION: A lid body 3 for underground embedded steel pipes, which is provided at an end of a steel pipe body that is embedded underground, comprises: a bottom surface part 31 that is in the same shape as an end surface of the steel pipe body, and that covers an opening on the end surface of the steel pipe body; and sliding contact parts 32 that are raised along the outer periphery of the bottom surface part 31 in the direction perpendicular to the bottom surface part. The sliding contact part 32 is angled inward from a normal line for the outer periphery of the bottom surface part 31.SELECTED DRAWING: Figure 2
【課題】鋼管の埋設方向先端面の開口を簡単な構造で塞ぐことができ、かつ鋼管の先端を塞ぐ蓋体に熱変形の生じにくい土中埋設鋼管蓋体を提供すること。【解決手段】土中に埋設される鋼管本体の端部に設けられる土中埋設鋼管用蓋体３は、鋼管本体の端面と同一形状とされ、鋼管本体の端面の開口を塞ぐ底面部３１と、底面部３１の外周縁に沿って面外方向に起立する摺接部３２とを備え、摺接部３２は、底面部３１の外周縁の法線よりも内側に傾斜する。【選択図】図２
