Abstract

The invention relates to a plastic inspection well leakage test device and a detection method, and belongs to the field of product performance detection and tests. The device comprises a machine base, a workbench, a seal ring, a water injection hole, a plastic inspection well, and a locking hoop. The machine base is fixed on a foundation. The workbench is disposed on the machine base. The seal ring is installed on the workbench. The workbench is provided with the water injection hole. The plastic inspection well is installed on the upper part of the workbench through the locking hoop. The middle part of the plastic inspection well is provided with a welding joint. The joint sealing point of the test device uses two-stage sealing and the hoop to lock and seal, so as to preferably ensure reliability of sealing and security of tests. The test device has multiple functions. Compressed air can be used to pressure test water of the test device, and leakage gas flow of the compressed air and decompression speed of pressure maintaining are observed to determine sealing property. The device is simple and reliable, and takes little area. The device is not limited by height of the inspection well, and is simple and convenient in operation, and low in cost.

Description

technical field [0001] The invention relates to a plastic inspection well sealing test device and a detection method, belonging to the field of product performance detection and testing. Background technique [0002] Inspection wells, commonly known as "cellar wells", are shafts built at intervals of underground pipelines. They are one of the underground infrastructures of urban roads. They are mainly used for maintenance of pipelines, removal of sludge, and connection of pipelines in different directions and heights. structures used. Most of them are located at bends, pipe junctions, pipe diameter or slope changes, water drops, and straight pipe sections. Due to its good sealing performance, the plastic inspection well can be constructed around the clock without being restricted by the weather. It can be combined separately, and the height can be adjusted up and down. With the advantages of low cost and other advantages, it gradually replaced the inspection well of the tr...
