GROUND EMBEDDED TYPE UNDERGROUND WATER OBSERVATION HOLE PROTECTING DEVICE

摘要

The present invention discloses a ground embedded type protecting device for protecting underground water observation holes. The ground embedded type protecting device of the present invention can be opened only when a locking member is used, and minimize ground protrusions. Therefore, the ground embedded type protecting device can protect observation equipment and facilities which are installed on the underground water observation holes in a downtown area, prevent contaminated surface water from flowing into the observation holes, secure easiness in the opening and closing of a sealing cover, external impact and corrosion durability, and a locking function for preventing losses, and also secure safety for passage of pedestrians and vehicles by minimally protruding from the surface of the ground.;COPYRIGHT KIPO 2020
