Sewer with dry weather channel constructed of pre-fabricated modular concrete components placed on sewer bed, with cement mortar between bed and modules

摘要

The sewer has a bed with a dry weather channel with a profile different from that of the bed. The channel (4) is constructed from pre-fabricated components (5), which are placed on the sewer bed and supported flat on it. The profiles of the sewer bed and the underside of the components correspond and include an intermediate space (9), which is filled with a hardening material (24). The dry weather channel components are of concrete or reinforced concrete, and the filler is cement mortar.
