Abstract
Drainage gutters for installation in the ground are known which comprise a gutter body at the upper edges of which are integrally cast frames into which a cover can be placed. As they are installed in the ground the drainage gutters are sealed from the ground along their upper edges by means of first sealing devices. To produce a watertight seal between each two drainage gutters that abut one another by their end faces, second sealing devices are provided. These sealing devices each comprise grooves that can be filled with a sealant. The known drainage gutters are not completely watertight with respect to the ground. It is proposed to provide connecting channels between the first and the second grooves, so constructed that the sealant of the first sealing devices can be introduced so as to be continuous with the sealant of the second sealing devices by way of a complete or integral transition region. In addition, instead of a bulk sealant, a compressed continuous sealing strip is used which, in the region of the connecting channels or chambers, comes into contact with the sealant of the first sealing devices (FIG. 5).
