Abstract

An apparatus and a method for testing leakage of a drain pipe are provided to allow an oil rotary pump used for a vacuum test to be applied to an air pressure test by connecting an exhaust port of the oil rotary pump to a sample section. A leakage test on a manhole(30) is performed by shutting off pipes inside the manhole with packers(41a,41b) and connecting a suction port(11) of an oil rotary pump(10) to a manhole cover(31), which hermetically seals the manhole, through an air transfer pipe(13a). A leakage test on a drain pipe is performed by injecting the air discharged through an exhaust port(12) of the oil rotary pump into a sample section through the air transfer pipe, where the sample section is formed by closing two ends of the pipe with the packers.

본 발명은 하수관로의 하수관과 맨홀에 대한 시험에 있어서,        The present invention in the test for sewage pipe and manhole of the sewer pipe,

일반적으로 하수관로의 누수시험은 하수관로를 신설한 후 시험구간을 밀폐한 뒤 물을 가득 채우고 비이커를 시험대상으로부터 수두 1m를 유지시켜 최초 30분 동안 방치시킨 다음 10분 동안에 측정된 누수량을 확인한다. 이와 같은 수두시험법은 과다한 물을 사용하게 되고, 물을 채우고 제거하는 시간이 길고, 급수차량 등이 동원되므로 교통체증의 간접적 원인이 되며, 시험시간이 길어지는 등의 불리함이 있어 근래의 까다로운 현장시공 환경에는 적용상의 경제적, 시간적 한계가 있다.       In general, the leak test of the sewer pipe is to be completed after the establishment of the sewer pipe, the test section is sealed, filled with water, and the beaker is kept for 1 meter of head from the test object for the first 30 minutes, and then the leakage measured in 10 minutes is checked. Such a hydrocephalus test method uses excessive water, takes a long time to fill and remove water, and induces traffic congestion due to a mobilization of a water supply vehicle. There is an economic and time limit of application in the field construction environment.

이를 대체하는 수단으로, 하수관의 시험구간을 밀폐시키고, 저압공기를 주입하여 일정압력 범위에서 감압되는 시간을 측정하여 누수여부를 판단한다.       As a means of replacing this, the test section of the sewage pipe is sealed, and low pressure air is injected to measure the time of decompression in a predetermined pressure range to determine whether there is a leak.

한편, 하수맨홀에 대한 시험도 실시하게 되는데, 하수맨홀의 경우 도로에 노출되는 주철뚜껑의 직경이 600㎜ 이므로 공기압시험을 할 경우 기밀패커가 튀어오르게 되는 위험성으로 인해 하수맨홀에 대해서는 저진공(-30 ~ -40㎪) 시험을 실시하게 된다.      On the other hand, the sewage manhole test is also conducted. In the case of the sewage manhole, the diameter of the cast iron lid exposed to the road is 600 mm. 30 to -40 ㎪) test.

하수관에는 시험구간 양단과 연결부를 기밀패커를 이용하여 밀폐시킨 다음 여기에 공기를 가압하며, 일반적으로 10 ~ 30 ㎪정도의 범위에서 이루어지며, 일정압력범위에서 감압 되는 시간을 측정하여 누수 여부를 판정한다. 하수맨홀의 경우 맨홀 내부에 연결된 부위를 기밀패커를 이용하여 밀폐시킨 다음 내부 공기를 배기시켜 진공을 형성하고, 일반적으로 하수맨홀의 경우 대기압보다 낮은 계기압력이 -30 ~ -40 ㎪정도의 범위에서 시험이 진행되며, 일정 압력범위에서 상승 되는 시간을 측정하여 누수 여부를 판단한다.        The sewer pipe is sealed at both ends of the test section by using an airtight packer and then pressurized with air. Generally, it is made in the range of about 10 to 30 ㎪, and the leak is determined by measuring the time of decompression in a certain pressure range. do. In the case of sewage manholes, the parts connected inside the manholes are sealed using airtight packers, and the internal air is evacuated to form a vacuum. Generally, in the case of sewage manholes, the gauge pressure lower than atmospheric pressure is in the range of -30 to -40 ㎪. As the test proceeds, the rise time in a certain pressure range is measured to determine whether there is a leak.

이와 같이 하수관로의 누수시험을 위해 공기압과 진공을 형성하기 위하여 각각으로 구성되는 공기압축기와 진공펌프를 사용하게 된다. 따라서 각각의 공기이송장치를 구비하여야 하는 불편함이 초래된다.       As such, air compressors and vacuum pumps, which are composed of air compressors and vacuum pumps, are used to form an air pressure and a vacuum for leak test of sewage pipes. This results in the inconvenience of having to provide each air transfer device.

따라서 하수관로의 특성상 통상적으로 40m 간격으로 맨홀이 개설되는 하수관로의 시험에는 연속적으로 공기압 및 진공시험이 이루어지고 편리하고 원활한 시 험이 진행될 수 있는 진공과 공기압축기능을 겸하는 단일 구성된 장치가 필요하게 된다.        Therefore, due to the characteristics of the sewage pipe, the test of the sewage pipe, which is normally opened at 40 m intervals, requires a single configured device that combines the vacuum and air compression functions to continuously perform the air pressure and vacuum tests and to perform a convenient and smooth test.

본 발명은 이를 해결하고자 하는 것으로, 본 발명의 목적은 하수관로의 시험에 있어서 맨홀의 진공시험을 위하여 사용되는 오일회전펌프를 이용하여 하수관의 공기압시험에도 적용할 수 있도록 오일회전펌프의 배기구를 시험구간과 연결하여 펌프를 회전시킴으로 시험구간에 공기압을 형성하여 하수관에 대한 공기압시험을 진행할 수 있는 장치와 장치의 이용방법을 제공하려는 것이다.The present invention is to solve this problem, an object of the present invention is to test the exhaust port of the oil rotary pump to be applied to the air pressure test of the sewage pipe using the oil rotary pump used for the vacuum test of the manhole in the test of the sewer pipe It is intended to provide a device and a method of using the device by forming a pneumatic pressure in the test section by rotating the pump in connection with the.
