PROBLEM TO BE SOLVED: To provide a construction method for lining plate for side ditch capable of eliminating almost al of reinforcing bar arrangement work, form assembly work, and disassembly and removal works at site and rationalizing the construction works. SOLUTION: This construction method for a lining plate for side ditch on a farm road consists of a process in which a three-dimensional truss 2 with a concrete permanent form in which a concrete board 22 is integrally formed in a lower part of a three-dimensional welded reinforcing bar 21 is spread and provided by inserting a U-shaped bare 3 into the inside of the three-dimensional welded reinforcing bar 21 so as to pull it out in advance and putting both ends of the three-dimensional truss 2 with concrete permanent form on a bridge base 11 of a side ditch 1, a process in which the U-shaped bar 3 is pulled out of the three-dimensional truss 2 with concrete permanent form after spreading and providing the truss 2, a connection process in which a projection 4 is driven and erected in the bridge base 11 on an inner side of a bent part of the U-shaped bar 3, a nd a process in which concrete is placed on the three-dimensional welded reinforcing bar 21 and each three-dimensional truss 2 with concrete permanent form is connected to form the lining plate.
