Underground construction pipe system for draining surface water in region of traffic areas, has insertion pipe inserted into front end regions of construction pipes with ends, and sealingly lying at construction pipes' inner circumferences

摘要

The system has two underground construction pipes (1a, 1b) connected with each other by an insertion pipe (3) at adjacent front end regions in an installed state. The insertion pipe is axially inserted into the both front end regions of the construction pipes with opposite projecting ends (4a, 4b), and sealingly lies at inner circumferences (2a, 2b) of the construction pipes. The projecting ends with an outer cross-section are adapted to an inner cross-section of the construction pipes. The insertion pipe is provided with a radially, outwardly extending collar arrangement (5) between the ends. The underground constructions pipes are reinforced concrete slot channels. The pipe ends are made of metal, thermoplastic, duroplastic, elastomer material, or layered or networked structure of two materials.
