Inspection and=or working pit for motor vehicles - consists of prefabricated U=shaped concrete parts which are joined to form unit and installed in the ground

摘要

The pit, which is let into the ground, has a base, left and right side walls, transverse end walls and an upper opening bounded by the side walls. It is made of several prefabricated concrete parts (17). The pit's length is determined by a U-shaped section (18) of at least one element, whose longitudinal walls form the pit side walls and whose base and longitudinal opening form the pit base and opening. The elements are joined together to form a pit unit. by connections (27). USE/ADVANTAGE - Pit is installed within very short time at minimal labour cost and achieve high dimensional stability to be achieved.
