1. A lining method comprising:
forming a plurality of lining panels so that in each lining panel, a filler is disposed inside a frame of a backing strip in a frame shape and a lining plate is fixed to cover inside of the frame of the backing strip;
making the plurality of lining panels adjacent to each other to combine the backing strips in such a manner that edges of the lining plates of the adjacent lining panels butt against each other at a position of the backing strip of one of the adjacent lining panels, and fixing the backing strips to a concrete surface of already-placed concrete; and
joining the edges of the lining plates of the adjacent lining panels by seal welding, wherein
the already-placed concrete is placed with a steel rod embedded therein prior to the fixing of the backing strip,
in each of the lining panels, a fitting part is provided in a joint of the backing strips of the adjacent lining panels,
a first lining panel which is one of the adjacent lining panels has the fitting part which protrudes to a second lining panel which is another of the adjacent lining panels, as being away from the concrete surface in a thickness direction, and
the second lining panel has the fitting part which protrudes to the first lining panel as being close to the concrete surface in a thickness direction.
