The invention "method and equipment for laying sewer pipes in foundations in residential, commercial and industrial building" is a new productive technology which eliminates the considerable disadvantages of known technical solutions and contains the equipment necessary for their implementation. Special mountable pipe-supporting slabs are mounted, on a mounting plane prepared at the exact slope of the sewer pipes, on the bottom of a foundation trench. Using a special formwork system, the foundation slab serving as a boundary of the conduit is concreted. After laying the sewer pipe with all the necessary mouldings on the pipe-supporting slabs, the conduit is closed using covering slabs laid by hand. Two special covering slabs lying against one another and having semicircular surfaces are positioned over each of the connection pieces, through which covering slabs the downpipes are introduced into the connection pieces. The cleaning-opening accesses are also made in this shape, so that the arrangement of shafts is dispensed with. This invention is particularly important for the trouble-free laying of pipelines made of pipe materials hitherto uncommon for these purposes, such as glass pipelines with glass mouldings which have specific advantages such as low roughness value, high hydraulic capacities, low pipe longitudinal inclination and hence smallest stressed constructional space.
