CIVIL ENGINEERING STRUCTURE, AND CONSTRUCTION METHOD THEREOF

PROBLEM TO BE SOLVED: To provide a construction method for a civil engineering structure constructed by laying and overlapping a fiber sheet, the construction method suppressing deviation of the sheet laid on top, and enabling the top sheet to be laid readily at a desired location.SOLUTION: A construction method for a civil engineering structure includes the following steps for: laying a first sheet having a fiber layer on a top surface; fitting a non-slip member on the first sheet; and laying a second sheet having a fiber layer on an under surface on the non-slip member. The non-slip member 11 includes a base 12 having a first surface 15 facing the first sheet side and a second surface 16 facing the second sheet side, a first surface side engaging element 17 protruding from the first surface 15 of the base 12 and having a folded-back part on a crown part, and a second surface side engaging element 18 protruding from the second surface 16 of the base 12 and not having the folded-back part at the crown part. The non-slip member 11 is fitted on the first sheet by the first surface side engaging element 17, and prevents deviation of the second sheet by the second surface side engaging element 18.SELECTED DRAWING: Figure 2 【課題】繊維製シートを重ねて敷設して土木構造を形成する際に、上側に敷設したシートがずれにくく、また所望の位置に上側のシートを敷設することが容易に行える土木構造の形成方法を提供する。【解決手段】上側面に繊維層を有する第１シートを敷設する工程と、第１シートの上に滑り止め部材を取り付ける工程と、滑り止め部材の上に、下側面に繊維層を有する第２シートを敷設する工程とを有する土木構造の形成方法であって、滑り止め部材１１は、第１シート側に面する第１面１５と第２シート側に面する第２面１６とを有する基盤１２と、基盤１２の第１面１５から突出し、頂部に返し部を有する第１面側係合素子１７と、基盤１２の第２面１６から突出し、頂部に返し部を有しない第２面側係合素子１８とを有し、滑り止め部材１１は、第１面側係合素子１７によって第１シートに取り付けられ、第２面側係合素子１８によって第２シートのずれを防止している。【選択図】図２
