Steel band pipe socket connection structure and connection method

Abstract

The invention discloses a steel band pipe socket connection structure and a connection method. The connection structure comprises a steel band pipe, heat-shrinkable pipes, a jack joint, a sealing washer and a socket joint, wherein the peripheries of the socket matching positions of the first connecting part of the jack joint, the second connecting part of the socket joint and the steel band pipe are sleeved with the heat-shrinkable pipes; the sealing washer is composed of a body, a baffle ring and a plurality of sealing rings. A containing groove does not need to be formed in the connection structure, the longer sealing washer can be mounted, the friction force generated by the sealing rings due to the axial exit of the socket joint is increased, and the socket joint is effectively prevented from being separated from the jack joint. The connection method utilizes the heat-shrinkable pipes. On one hand, the connection reliability of the socket joint, the jack joint and the steel band pipe is further ensured; on the other hand, the operation is convenient and fast, and the high production cost generated by using special equipment can be reduced.

Description

technical field [0001] The invention relates to the technical field of steel strip pipe connection, in particular to a steel strip pipe socket connection structure and a connection method. Background technique [0002] Steel belt pipe mainly includes steel belt reinforced polyethylene spiral corrugated pipe and buried steel-plastic composite winding drainage pipe, which are widely used in sewage and drainage projects. In order to solve the problem of poor sealing effect of the traditional hot-melt belt connection method for connecting steel strip pipes, a socket-type connection structure has emerged. However, before this connection structure is connected, special equipment is required to heat and melt the socket joint and socket joint Connecting to the steel belt pipe has the problems of high cost of special equipment, high energy consumption and low processing efficiency. When connecting, insert one end of the socket joint into the socket joint, and put an O-shaped sealing...

AI Technical Summary

Problems solved by technology

When this connection method is actually used, on the one hand, the socket joint will be separated from the socket joint and loosen due to the insufficient anti-separation effect of the sealing ring, which will affect the sealing effect; The connection with the steel strip pipe is not reliable enough, and the joints have fallen off during the construction process, so this connection method needs to be improved
