FIELD: construction.
SUBSTANCE: segment for restoration pipe contains an internal surface plate, forming the inner ring surface, side plates and end plates, secured vertically at the peripheral edge of the inner surface of the plate. The inner surface plate, side plates and end plates are made as a single piece of plastic. To install the segmented reduction tube inside the existing pipe, the segments are connected in the circumferential direction and along the pipe. Each of the side plates at the end, near the end plate, has an opening used for the process of joining the segments in the circumferential direction. Through the opening it is possible to insert the connecting element and to easily connect the segments in the circumferential direction.
EFFECT: aperture, formed in the side plate is made in such a way that the filling material, entered into the space between the existing pipe and the replacement pipe segment, flows or flows out through this opening.
