TUBULAR STRUCTURE AND METHOD OF MANUFACTURING TUBULAR STRUCTURE
To provide a tubular structure hardly to be broken by earth pressure even when buried in a soil layer at a relatively deep site 10 m or more below the ground surface in a downward vertical direction and hardly to be floated from the depth at which it is originally buried.SOLUTION: A tubular structure of this invention further comprises an outer shell section including a metal-made outer shell body part which is formed tubularly around an axis line and inside of which a tubular body part is formed. The outer shell body part includes an outer peripheral coating part that coats an outer peripheral surface of the tubular body part along the entire periphery. The tubular structure has an apparent specific gravity of 0.84 or more and 1.46 or less and is buried in a soil layer formed at a site 10 m or more below the ground surface in a downward vertical direction, the soil layer having an apparent specific gravity of 1.4 or more and 2.1 or less.SELECTED DRAWING: Figure 4
【課題】地表面から鉛直方向下方に１０ｍ以上という比較的深い位置で土層に埋設されても土圧によって破損し難く、且つ、当初の埋設深さから浮上し難い管状構造物を提供することを課題とする。【解決手段】管状構造物は、軸線回りに管状に形成されて内側に管状本体部が形成される金属製の外殻本体部を有する外殻部を更に備えており、外殻本体部は、管状本体部の外周面を全周に亘って覆う外周被覆部を備える。そして、管状構造物は、見掛け比重が０．８４以上１．４６以下であり、地表面から鉛直方向下方に１０ｍ以上の位置に形成された土層であって見掛け比重が１．４以上２．１以下である土層中に埋設される。【選択図】図４
