본 발명은 상수도 이음부 이탈방지장치에 관한 것으로, 더욱 상세하게는 다수의 상수도관들을 연쇄적으로 관이음하여 상수도 시설을 구축할 때 상수도관들의 결속력을 증대하고, 관이음부에 토압이 직접 전가되지 않도록 하여 상수도관의 이탈을 막을 수 있도록 한 상수도 이음부 이탈방지장치에 관한 것이다.The present invention relates to a device for preventing the separation of water supply joints, and more particularly, to increase the binding force of water supply pipes when constructing a water supply facility by jointly connecting a plurality of water pipes, and directly transferring earth pressure to the pipe joints. The present invention relates to a water supply joint prevention device for preventing the separation of the water supply pipe.

일반적으로, 공장, 주택 및 각종 시설에 상수를 공급하는 상수도관은 지상의 공간확보 및 생활환경미화를 위해 일정한 직경과 길이를 갖는 다수의 상수도관을 일렬로 연통되게 연결한 구조물이 안착될 수 있도록 충분한 공간으로 지면을 절개하고, 이곳에 상기 상수도관 구조물을 길이방향을 따라 순차적으로 안착시킨 후 토사로 매몰하여 이루어진다.In general, water supply pipes for supplying water to factories, houses, and various facilities are installed so that a structure in which a plurality of water pipes having a constant diameter and length are connected in a line in order to secure space on the ground and beautify living environment may be installed. The ground is cut into a sufficient space, and the water conduit structure is sequentially seated along the longitudinal direction and then buried in soil.

그러나, 종래 기술에 의한 상수도 이음부에 따르면, 단순히 상수도관을 볼트로 체결하거나 나사 체결하는 것이기 때문에 구조적으로 상수도관 자체 강도보다 관이음부가 매우 취약하다. 따라서, 지반 침하가 발생되는 등 외력이 가해지면 상기 상수도관의 관이음부가 먼저 파손되어 상수도관들이 이탈되는 문제점이 있다.However, according to the water supply joint according to the prior art, it is structurally weaker than the strength of the water pipe itself because it is simply bolted or screwed to the water pipe. Therefore, when an external force is applied such as ground subsidence, the pipe joint of the water supply pipe is broken first, and the water supply pipes are separated.

또한, 토압이 관이음부에 직접 가해지기 때문에 토압에 의해 관이음부가 변형되어 역시 상수도관이 이탈되는 문제점이 있다.In addition, since the earth pressure is applied directly to the pipe joint, there is a problem in that the pipe joint is deformed by the earth pressure and the water pipe is separated.

본 발명은 상기한 종래 문제점을 해결하기 위한 것으로, 상수도관들간의 결속력을 증대함과 아울러 토압이 상수도관의 관이음부에 직접 가해지지 않도록 하여 어떠한 외력에 의해서도 상수도관이 관이음부에서 이탈되지 않도록 한 상수도 이음 부 이탈방지장치를 제공하려는데 그 목적이 있다.The present invention is to solve the above-mentioned conventional problems, to increase the binding force between the water pipes and to prevent the earth pressure from being applied directly to the pipe joints of the water pipes, the water pipes are separated from the pipe joints by any external force. The purpose of the present invention is to provide a dewatering device for water supply joints.

상기 목적을 달성하기 위한 본 발명에 따른 상수도 이음부 이탈방지장치는, 상수도관의 단부가 볼트로 체결되며, 상기 상수도관들의 마주하는 단부에는 서로 조여지면서 상기 상수도관의 관이음부를 밀폐하는 덮개부를 갖는 제1,2지지링이 설치됨을 특징으로 한다.In order to achieve the above object, the apparatus for preventing the separation of a water supply joint according to the present invention includes an end portion of the water supply pipe fastened by a bolt, and a cover for sealing the pipe fitting of the water supply pipe while being tightened with each other at opposite ends of the water supply pipes. It characterized in that the first and second support rings having a portion is installed.
