[0002] In recent years, with the country's increased investment in infrastructure and the development of urbanization, the country has invested greatly in public facilities. Whether it is a large city, a small or medium-sized city, or an economically developed town, as long as there are public facilities such as tap water, street lights, drainage, telecommunications, gas, power, and fire protection, inspection wells need to be installed. However, most inspection wells are set on the road, so when the inspection well is constructed, it will inevitably affect road traffic. Therefore, in order to prevent road traffic from being affected for a long time, the construction speed of the inspection well cover is particularly important. The on-site pouring period is long, and the advantages of prefabricated covers can be better reflected.
