Description

Tight joint type piping connection structure {Tight joint type piping connection structure}

The present invention relates to a piping connection structure, and more specifically, in underground piping work through which fluid passes, a socket pipe and a socket pipe are connected, and then the split ring and pressure ring structure fasteners installed on each are fastened with long bolts. This relates to a Tyton joint-type piping connection structure that increases construction convenience and prevents separation and water leakage by tightening and tightening.

Pipes for water supply that are large in diameter and subject to high water pressure are installed by continuously connecting cast iron pipes of a certain length underground. At this time, water leaks or pipe separation may occur at the connection between pipes due to high water pressure and external shock, so a pipe connection structure is used to ensure a strong connection and prevent water leaks.

The Tyton joint cast iron pipe currently being constructed in Korea is a 6M long straight pipe, and in curved sections, KP mechanical joint type deformed pipe and anti-separation rolling wheels are used.

Tyton jointed deformed pipe has a structure in which only a Tyton rubber ring is inserted inside the pipe, just like a straight pipe. This is the same low-pressure structure as the general pressure ring construction of the KP mechanical type, so it cannot be used for deformed pipes other than straight pipe, and high pressure is used in the curved pipe part. A tear-off prevention wheel that can withstand this must be used.

Therefore, in order to smoothly manufacture and apply the Tyton jointed deformed pipe to the field, a structure that can effectively prevent the pipe from coming off is required.

The Tyton joint type fastener is a product that is fastened to the Tyton joint type deformed pipe to prevent the deformed pipe from coming off even under high pressure. A split ring is fastened to the exterior of the socket, and with the fastener fastened to the receiver, the fastener and the receiver pipe are integrated. In a structure that allows this, the bolt bound to the socket split ring is inserted into the fastener hole fastened to the receiver, and the receiver and socket are firmly fixed by a nut tightening method to prevent the pipe from being separated.

At this time, the straight pipe construction method of Tyton joint is used by placing the conduit pipe against the entrance of the socket and pushing it with the hydraulic power of an excavator. However, unlike straight pipe construction, the curved pipe deformed pipe cannot be constructed with an excavator because the center position is unstable. There were many places that were not there.
