Description

Water Supply Pipe Connecting Unit The present invention relates to a water pipe detachment prevention device, and more specifically, to a water pipe detachment prevention device that prevents the connection part of a water pipe installed to be buried underground from being damaged by fluid pressure and enables the installation position of the water pipe to be firmly maintained. A water supply pipe refers to a pipe used to transport and distribute water from a water source. The water pipes mentioned above are installed to supply tap water to places such as houses and factories that receive water from a water source for use, and are generally installed in a form that is buried underground. This is installed by excavating a specific location underground for the installation of water pipes, burying the pipes, and then applying concrete or asphalt over the buried pipes to prevent the pipes from being damaged or their installation location from changing due to impacts occurring above ground. At this time, there was a problem in that the installation location of the water pipes could be changed if the shape of the underground changed due to rainwater being absorbed into the ground. In addition, conventional water pipes are typically formed in a tubular shape to transport tap water over a certain distance; these tubular water pipes are buried underground, and the connecting parts are joined using fastening means such as bolts and nuts. For example, a conventional water pipe connection device has been proposed in which, as in document (1), a packing or the like is positioned between water pipes positioned facing each other, and then the connection part of the water pipes is connected with a bolt and a nut. However, conventional water pipe connection methods such as those described in literature (1) had the problem that the connection part of the water pipe could be damaged due to fluid pressure, and the location of the water pipe could change depending on the shape of the underground area where the water pipe is installed, which could cause damage to the connection part of the water pipe.

FIG. 2 is another cross-sectional view illustrating the state in which the water pipe detachment prevention device of the present invention is coupled. FIG. 3 is another cross-sectional view illustrating the state in which the water pipe detachment prevention device of the present invention is coupled.
