In order to ensure beautiful, most people choose to conceal. In this process, the construction personnel should pay attention to the need to lay a viewing port on each floor of the riser for irrigation experiments, and abnormalities in the later stages can be resolved in time. The device riser generally advocates two people to cooperate up and down, one person hangs the line from the upper pipe hole, and the other person fastens the upper part of the prefabricated pipe, and sets the flange gland and the rubber ring on the flexible cast iron drainage pipe socket in order, and pulls it The holder pierces the riser socket into the socket. A riser should be set for each pipe section of the riser together. A special riser must be provided for the special branch pipe and the main watershed, usually two to three per floor to ensure safety. After waiting for the pipe to pierce into the socket, the people at the grass-roots level need to correct the direction of the viewing port. The upper-level person can use a wooden wedge to temporarily lock, straighten, and fasten the pipe at the floor hole. After the riser device is completed, the concrete is used to block the holes in layers. The high-rise building or pipeline well should be fixed with steel as the plan or atlas requirements.
