Abstract
The invention discloses a support member, comprising an annular body and a support projection disposed on an end surface and/or an inner wall of the annular body, wherein the support projection extends from the end surface of the annular body in an axial direction of the annular body and is configured to extend into an interior of a pipe member to support the pipe member. The pipe member is supported so that the pipe member is prevented from deformation under the action of a fastener, and effective and reliable abutting of the adjacent pipe members located on two sides of the support member is ensured, thereby improving the sealing performance and waterproofing performance at the abutment of the adjacent pipe members to enable a line pipe system formed by the pipe member to be more safe and reliable.
