Document Type and Number:
Japanese Patent JP2019044562
Kind Code:
A
Abstract:
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
