Well lid system for airport and usage method thereof

Abstract

The invention discloses a well lid system for an airport and a usage method of the well lid system. The well lid system comprises a well loop, a well lid body, a bolt and a locking part, wherein protruding lid tongues are arranged on the edge of the well lid body, grooves matched with the lid tongues are reserved on the inner circle of the well loop, the lid tongues are inserted into the grooves, a sink hole is drilled in the well lid body, a screw hole is reserved at a position, corresponding to the sink hole, of the well loop, the bolt penetrates through the sink hole and is screwed into the reserved screw hole, the well lid body and the well loop are tightly connected, vertical grooves and rotating grooves are arranged on the cylindrical surface at the upper part of the sink hole, stop pins on the locking part are screwed into the rotating grooves by penetrating through the vertical grooves, and a hexagon prism on the locking part is inserted into a first hexagon hole at the top of the bolt to prevent the bolt from loosening. When the well lid system is used in the airport, the well lid system can be prevented from being blown up by a snow sweeper, and the potential safety hazard caused by the loose bolt due to vibration can be avoided, thus the safety of the airport personnel and facilities can be well protected. The well lid system is simple to operate, economical and practical.

Description

technical field [0001] The invention relates to a manhole cover system for airports, in particular to a manhole cover for airports that can prevent being blown up and sucked up by snow removal vehicles. Background technique [0002] Manhole covers are an important part of airport drainage systems and other power systems. At present, most of the manhole covers in the airport are directly placed on the well circle without other fixing measures. When the snow removal vehicle is working, a huge negative pressure will be generated above the manhole cover, and the huge pressure difference between the bottom and the top of the manhole cover will easily blow up the manhole cover. This will cause great danger to airport maintenance personnel and equipment. Contents of the invention [0003] The task of the present invention is to solve the above-mentioned defects existing in the prior art, and to provide a manhole cover system for an airport and its application method. [0004] T...
