Description

【考案の詳細な説明】本考案は薬液注入管等の４流路管体の接続装置
に関する。[Detailed Description of the Invention] The present invention relates to a connection device for a four-channel pipe body such as a chemical liquid injection pipe.

近年、薬液注入工法の高度化に伴つて多流路注
入管の要請が高まつている。ところが、重合管で
たとえば４流路を構成しようとすると、重量的に
大となるばかりでなく管内抵抗が大きくなるなど
の問題がある。そこで、重合管ではなくして、外
管内に平行流路を構成する場合、接続部の流路を
どのように採るかはきわめて難しい問題である。 In recent years, as chemical injection methods have become more sophisticated, the demand for multi-channel injection pipes has increased. However, if an attempt is made to construct, for example, four channels using polymerized tubes, there are problems such as not only the weight of the tube becomes large but also the resistance inside the tube increases. Therefore, when constructing a parallel flow path in the outer tube instead of using a polymer tube, it is an extremely difficult problem to decide how to form the flow path at the connecting portion.
