LEVEE STRUCTURE AND CONSTRUCTION METHOD OF LEVEE STRUCTURE
To provide a levee structure that is easy to construct and has a simple structure, yet can hold a robust slope wall part for a long period of time, and a construction method of the levee structure.SOLUTION: A levee structure 1 includes: a bank part 2 that is formed adjacent to a paddy field at a predetermined height, and has a top part 21, a paddy field side slope part 220 inclined downward from the top part 21 toward the paddy field, and an engagement recessed part 23 including an internal corner part 231 formed in a region in the middle of a slope of the paddy field side slope part 220 in a direction substantially parallel to the top part 21 and an intermediate step part 232 having a predetermined width connected to the inner corner part 231; and a slope wall part 3 that includes a wall surface part 31 covering at least all or a part of the paddy field side slope part 220 of the bank part 2 and an engagement projecting part 32 engaged with the engagement recessed part 23 on the bank part 2 side of the wall surface part 31, and has a higher rigidity than the bank part 2.SELECTED DRAWING: Figure 2
【課題】施工が容易で、簡易な構造でありながら、長期に亘って堅牢な法面壁部が保持可能な畦畔構造体、及び、畦畔構造体の施工方法を提供する。【解決手段】畦畔構造体１は、水田に隣接して所定の高さで形成され、天部２１、該天部２１から水田の方向に下り傾斜する水田側法面部２２０、及び、該水田側法面部２２０の斜面途中の領域に、前記天部２１と略平行となる方向に形成された入隅部２３１と該入隅部２３１に連設した所定幅の中間段部２３２を含む係合凹部２３、を有する、盛土部２と、該盛土部２の少なくとも前記水田側法面部２２０の全部又は一部を覆設した壁面部３１、及び、該壁面部３１の前記盛土部２側に、前記係合凹部２３に係合した係合凸部３２を含み、前記盛土部２よりも高剛性を有する、法面壁部３と、を備える。【選択図】図２
