System for out-put and security of leakage test data for leakage test apparatus of waterworks and sewer

摘要

Tightness testing device water-tight test image drawn and safety of the data in accordance with the present invention is that to put into the sewer by the trenchless method applied to a water-tight test apparatus capable of performing a water-tight test of the sewage pipe, the inflow of outside air It is expanded by the expansion member installed on both ends of a shaft having a predetermined length so as to seal any space of the sewer; Up member provided on the side of the entry side inflation member of the sewage pipe while reciprocated and rotated by the actuators installed in the image pick-up to a predetermined region within the sewage pipe of the sewage pipe entry side inflation member; Air injection member for injecting air at a predetermined test area of ​​the sewage pipe inside formed between the inside and each of the expansion element of the expansion member; And displaying a water-tight test data value by measuring the air pressure accordingly be applied to the interior of the air injection during the time predetermined by the member based on the amount of air injected into the interior of the testing space and an expansion member, wherein the test area and the expansion member may be, a group which the water-tight test data value can not be deliberately operated in a water-tight test data values ​​corresponding to the set injection time is captured while air injection time predetermined by the photographing member said to be output on the external display and a gauge assembly is installed on the side of the sewage pipe entry side inflation member.
