Abstract

The invention discloses a full burglary-prevention inspection well lid which can be assembled and disassembled only by special tools. The inspection well lid comprises an inspection well lid framework (111), an inspection well lid body (311) and the like. As the inspection well lid body (311) is provided with burglary-prevention screw spikes and screwable telescopic burglary-prevention crossbars are arranged below an inspection well lid bottom face (313), and the like, and special tools for assembling and disassembling the screw spikes and the crossbars are respectively configured for the screw spikes and the crossbars, the inspection well lid only can be assembled and disassembled only by the special tools for the inspection well lid, and therefore, the full burglary-prevention goal is achieved. The inspection well lid can be used as a burglary-prevention and terrible destruction-prevention inspection well lid widely installed and used in a large number of cable inspection wells of outdoor underground power, telecom and the like and municipal facility underground sewage conduit inspection wells and the like, and is remarkable in social benefit.

Description

technical field [0001] The invention discloses a matching piece for the construction of underground facilities, which includes a manhole cover frame 111 and a manhole cover body 311. Since the manhole cover body 311 is equipped with anti-theft screws and the manhole cover bottom surface 313 is equipped with a rotatable The movable and telescopic anti-theft horizontal bolt etc. are equipped with special tools for assembly and disassembly respectively, so that the present invention can not be assembled and disassembled by any tool except the special tools, thereby achieving the purpose of 100% anti-theft. The present invention can be widely applied to the installation and use of anti-theft and anti-terrorist inspection well covers for a large number of outdoor underground electric power, telecommunications and other cable inspection wells, underground sewage pipe inspection wells of municipal facilities, etc., and has obvious social benefits. Background technique [0002] So f...
