The plastic inspection chamber is one of the rapidly developing products in the field of drainage in China for the past few years. At present, plastic inspection chamber is mainly made of PP, PE, PVC and so on. The manufacturing technologies include injection molding, rotational molding, mechanical assembly and others. Plastic inspection chambers have developed very fast in the past five years and there are nearly one hundred manufacturing enterprises in China till now. Plastic inspection chamber is an important component which is convenient for regularly inspecting, cleaning, dredging underground pipe systems, so its service life directly determines the functions of underground pipe systems, and is an important factor for the plastic inspection chambers to get sustainable development in China
The relevant domestic and foreign standards clearly require that the service life of plastic inspection chambers should be more than 50 years. The test methods used for evaluating the service life mainly include structural integrity tests, and so on. And the structural integrity tests remain a gap in china. This article details the test principle of structural integrity. We choose China’s typical plastic inspection chambers - injection molding inspection chambers as study subjects, study the structural integrity of this type of plastic inspection chambers in accordance with the standard BS EN 13598-2:2009, analyze the effect of different structures and depth of using on the test results, evaluate the quality of domestically manufactured plastic inspection chambers, and provide some advices on the structure design and materials selection of plastic inspection chambers.
