Title: Innovations by Shinobu Satake in Pipe Lining Technology
Introduction
Shinobu Satake is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of pipe lining technology, holding a total of 3 patents. His innovative methods have improved the efficiency and effectiveness of lining pipes, particularly in urban infrastructure.
Latest Patents
One of Satake's latest patents involves a method of lining the internal surface of a pipe with a larger diameter portion. This method includes inserting a first pig, which is a spherical body made of resilient material, into the pipe. The first pig has a diameter larger than the pipe's inner diameter and features grooves for air escape. Following this, a necessary amount of resin is injected into the pipe, and a second pig is inserted behind the resin. The second pig has a smaller diameter, allowing for the formation of a resin lining layer of desired thickness. Positive pressure is then applied to move the pigs and resin through the pipe, ensuring a uniform lining.
Another patent focuses on lining an existing underground main pipe that involves a branch pipe. This method starts with injecting resin into the branch pipe and introducing a pig apparatus. Positive pressure is applied to move the resin and pig apparatus forward until the branch pipe is fully lined. The pig apparatus is then stopped at the branching position, isolating the branch pipe from the main pipe. Subsequently, resin is injected into the main pipe, and a lining pig is used to create a resin lining layer along its entire length.
