CONSTRUCTION METHOD OF SIDE DITCH, AND UNDERGROUND EMBEDDED CYLINDER MEMBER
To provide a construction method of a side ditch and an underground embedded cylinder member, which can contribute to saving of space for embedding electric wires etc. and can easily set inclination of a drainage channel to the inclination according to a site.SOLUTION: The construction method of the side ditch comprises laying underground embedded cylinder members 12 in series in a lower stage and laying free gradient side ditch members 11 in series in an upper stage, through the following steps: a laying ditch open-cutting step of open-cutting a ditch 2; a foundation forming step of forming a foundation 3 in a bottom of the ditch 2, a cylinder member laying step of laying the plurality of underground embedded cylinder members 12 on the foundation 3 while sequentially communicating penetration space part 27; a free gradient side ditch laying step of placing the free gradient side ditch member 11 having a drainage space 18 between right and left side wall portions 16 and an open lower surface on the underground embedded cylinder member 12 and sequentially connecting the drainage spaces 18; and a drainage space bottom forming step of placing invert concrete 13 inside the connected free gradient side ditch member 11 and forming the bottom of the drainage space 18 of the free gradient side ditch member 11 on the underground embedded cylinder member 12.SELECTED DRAWING: Figure 4
【課題】電線等を埋設するスペースの節約に寄与でき、しかも排水路の傾斜を現場に応じた傾斜に容易に設定可能な側溝の施工方法、および、地中埋設用筒部材を提供する。【解決手段】溝２を開削する敷設用溝開削工程と、溝２の底部に基礎３を形成する基礎形成工程と、該基礎３上に地中埋設用筒部材１２を順次貫通空部２７を連通させながら複数本敷設する筒部材敷設工程と、地中埋設用筒部材１２上に、左右の側壁部１６の間を排水空間１８とし下面が開口した自由勾配側溝部材１１を載置して排水空間１８を順次接続しながら複数敷設する自由勾配側溝敷設工程と、接続した自由勾配側溝部材１１の内部にインバートコンクリート１３を打設して地中埋設用筒部材１２上に自由勾配側溝部材１１の排水空間１８の底部を形成する排水空間底部形成工程と、を経て、下段に地中埋設用筒部材１２を一連に敷設するとともに、その上段に自由勾配側溝部材１１を一連に敷設する。【選択図】図４
