The present invention relates to a device for jointing an underground water pipe. According to the present invention, the device for jointing an underground water pipe has an excellent connection force as a contact area of first and second semicircular connection loops and a joint pipe fixed between the pipes is wide. The device for joining an underground water pipe improves a coupling force between the first and second semicircular connection loops and the joint pipe by preventing a bolt member from be shaken due to vibration of an underwater motor pump. The device for jointing an underground water pipe can protect a cable and a pipe by strongly holding a power cable for an underwater motor pump, a cable for a sensor for calculating the discharge amount of the underground water, and a water level measuring pipe for calculating. |
