Cast pipe self anchored interface

Abstract

A self-anchor joint structure for cast pipes is disclosed. The plug end of one cast pipe is inserted in the socket end of another cast pipe. A sealing ring is tightly pressed in the slot in said socket. A fastening hoop with the screw holes for locking said plug end and socket end is arranged around said joint circumference. The screw bolts are turned in said screw holes to lock the plug end, socket end and fastening hoop together.

Description

(1) Technical field [0001] The invention belongs to an interface structure for connecting TJ-type cast pipes into pipelines. (two), background technology [0002] At present, when the TJ cast pipe is connected into a pipeline, a sealing ring is placed in the inner groove of the socket of the casting pipe, and the socket of another casting pipe is inserted into the socket of the casting pipe, and the sealing ring is tightly squeezed Between the socket and the socket of the cast pipe to achieve sealing and anti-slip. However, cast pipes can only be constructed one by one when they are connected and assembled, and the efficiency is low. The width of the pipe laying ditch that needs to be dug is large, time-consuming and laborious, and the construction period is long. Due to the construction in the pipe laying ditch, the work is inconvenient and the environment is poor. The paved pipeline has poor pressure bearing capacity and poor resistance to radial deformation. When the t...

AI Technical Summary

Problems solved by technology

However, cast pipes can only be constructed one by one during connection and assembly, which is inefficient, and the width of the pipe laying ditch that needs to be dug is large, time-consuming and laborious, and the construction period is long

Due to the construction in the pipe laying ditch, the work is inconvenient and the environment is poor

The paved pipeline has poor pressure bearing capacity and poor resistance to radial deformation

When the temperature of the transported material increases or decreases and the length of the cast pipe changes, it is easy to leak due to the slippage of the socket of the cast pipe

In the construction of pipelines crossing rivers, lakes or over mountains, slippage and leakage occurred many times and rework occurred, which greatly increased the cost and extended the construction period.
