Description

Technical Field

[0001] The utility model relates to the technical field, and more specifically, to a manhole cover testing device for engineering detection. Background Art

[0002] Manholes are underground spaces for the transfer and control of urban underground pipelines. Their ground entrances and exits are called manhole mouths or manholes. Manholes are usually covered by manhole covers, and engineering inspection is an important task to ensure the safety of construction projects that have been built, are under construction, and will be built. It is an important task to test the foundation, building materials, construction technology, and building structure related to the building during the entire construction process. Manhole cover test equipment is needed in the process of manhole cover inspection and testing, but most traditional test equipment directly puts the manhole cover on the test platform and performs pressure testing through pressure sensors and presses.
