Abstract
A lining method includes fixing a backing strip in a frame shape to a concrete surface of already-placed concrete so that the backing strip protrudes from the concrete surface; disposing a filler inside a frame of the backing strip; making edges of a plurality of lining plates butt against each other at a position of the backing strip to cover the backing strip and the concrete surface; and joining the edges of the lining plates by seal welding.
Claims3
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.

A lining to prevent leakage into already-placed concrete, comprising:
- a plurality of lining panels,
- each lining panel including
- a backing strip formed in a frame shape,
- a filler disposed inside a frame of the backing strip, and
- a lining plate covering inside of the frame of the backing strip and fixed to the backing strip, wherein
- the plurality of the lining panels are arranged adjacent to each other to combine the backing strips, and the backing strips are fixed to the already-placed concrete, so that edges of the lining plates of the adjacent lining panels butt against each other, wherein
- one surface of the backing strip is in contact with the concrete surface,
- an anchor inserted from other surface of the backing strip to inside of the concrete, wherein,
- 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.
