Description

Technical Field

[0001] The utility model relates to an improved armored clamping ring interface device for a prestressed steel cylinder concrete pipe, belonging to the technical field of prestressed steel cylinder concrete pipes. Background Art

[0002] Prestressed concrete cylinder pipe refers to a water pipe made by winding circumferential prestressed steel wire around a high-strength concrete pipe core with a steel cylinder, and then spraying a dense cement mortar protective layer on it. PCCP uses a steel socket welded to the steel cylinder. The socket has grooves and rubber rings to form a flexible joint with sliding rubber rings. To a certain extent, it can meet the requirements of smaller turning angles, generally less than 0.5 degrees, to adapt to uneven settlement. However, for larger turning points, if thrust-stopping measures such as concrete ballast are not taken, the axial unbalanced force generated by the internal water pressure, which is related to the pipe diameter, turning angle, and pressure value inside the pipe, will cause the pipe to be pulled apart at the interface.

[0003] The traditional armored joint of prestressed concrete cylinder pipe is to set two clamping rings on the socket and spigot of PCCP to clamp the pipe joint and lock it with bolts, so that the pipes on both sides of the clamping ring are connected as one. The axial tension is transmitted through the steel cylinder to prevent the pipe joint from disengaging. However, the use of two clamping rings, clamping the pipe joint and locking it with bolts may result in an insufficiently tight connection and poor strength. Therefore, we provide an improved armored clamping ring joint device for prestressed concrete cylinder pipe to solve the above problems. Utility Model Content
