摘要

A drain pipe intended for use when laying surface-water drains, manholes and like structures, particularly in frost susceptible ground. The drain pipe has a length such as to enable the pipe to connect a drain cover with a drain-bottom part or a tubular raising member which is connected directly to the drain-bottom part or is connected to the drain-bottom part via one or more additional raising members. The outer form of the drain pipe is slightly conical over at least a part of the length of the pipe, the pipe being arranged to be mounted so that its widest end faces downwards and can be inserted into a socket or collar of the aforementioned drain-bottom part or of a raising member. The invention also relates to a method of laying a drain while using such a drain pipe, and to a drain laid in accordance with the method.
