摘要： Method for producing a construction element, in particular a tunnel element, from a curing material, such as concrete, in a mold, said construction element being provided with a watertight seal on at least one side thereof, wherein a gasket is used comprising a deforming body which is produced from a yielding material, such as rubber. According to the invention a base is produced from a relatively strong material, which base may or may not be detachable from the deforming body. Said base with or without said deforming body is placed against an inner side of the mold, said curing material is cast in the mold, and said curing material is cured to form said construction element with said watertight seal.

摘要： A waterstop joint includes a sealing strip made of an elastomer or a rubber like material, two bulged portions, each bulged portion extending along a different one of said two peripheries of the sealing strip, two fixation strips, each fixation strip extending from a different one of said two bulged portions, and extending in the same plane as the sealing strip, and a multitude of injection tubes for injecting a curing liquid, such as epoxy resin. One outer end of each of said injection tubes is mounted to, or in the vicinity of, one of the steel strips. The outer end of each of the injection tubes is mounted to, or immediately adjacent to, one of said two bulged portions.
