[0002] For drainage pipes, pressure testing is an important process in pipeline construction. The external pressure load device is mainly used to measure concrete pipes and reinforced concrete pipes under specified crack loads to check whether there are cracks and the destructive load when the bearing capacity is lost. The purpose is to check the strength of the pipeline or equipment.
[0003] During use, the existing drainage pipe external pressure load testing machine can detect the drainage pipe, but it cannot automatically adjust the height of the reaction frame, which requires the staff to manually lower the reaction frame to the specified position, and wastes a lot of time to fix it. At the same time, it is also impossible to effectively fix the drainage pipe body, resulting in the drainage pipe body being offset during the inspection process, causing the drainage pipe body to fall to the outside of the equipment, causing injuries to the staff and damage to the drainage pipe body, reducing the automation and fixity of the traditional drainage pipe external pressure load testing machine. For this reason, a drainage pipe external pressure load testing machine is introduced. Utility Model Content
