Zusammenfassung:To provide a burial structure of a duct line which can be constructed at low costs, and to provide a burial method.SOLUTION: The invention relates to a burial structure of a duct line which is buried in the ground and includes: a bent pipe unit including a bent pipe; a pair of connection units connected to both end parts of the bent pipe unit; a pair of straight pipe units connected to both end parts of the connection units and including at least one straight pipe; a first filler filling the periphery of the bent pipe unit in the ground; and a second filler filling peripheries of the connection units in the ground. The first filler or the second filler fills the peripheries of the straight pipe units in the ground. The first filler is formed by a material which fixes each unit in the ground and the second filler is formed by a material which allows movement of each unit in the ground.SELECTED DRAWING: Figure 6 【課題】低コストで施工することができる管路の埋設構造及び埋設方法を提供する。【解決手段】本発明は、地中に埋設される管路の埋設構造であって、曲管を含む曲管ユニットと、前記曲管ユニットの両端部に連結される、一対の連結ユニットと、前記連結ユニットの両端部に連結され、少なくとも一つの直管を含む、一対の直管ユニットと、前記地中で前記曲管ユニットの周囲に充填される第1充填材と、前記地中で前記連結ユニットの周囲に充填される第2充填材と、を備え、前記地中で前記直管ユニットの周囲には、第1充填材または第2充填材が充填され、前記第1充填材は、前記各ユニットを前記地中に固定する材料で構成され、前記第2充填材は、前記各ユニットの前記地中での移動を許容する材料で構成されている。【選択図】図6
