Abstract

The invention discloses a 100 percent anti-theft inspection well cover. The 100 percent anti-theft inspection well cover includes an inspection well cover frame (111), an inspection well cover body (311) and other components. Through anti-theft components such as anti-theft screws which are mounted on the inspection well cover body (311), and a rotatably telescopic anti-theft bolt which is mounted below an inspection well cover bottom surface (313), as well as special assembly / disassembly tools for the components, the 100 percent anti-theft inspection well cover cannot be assembled / disassembled through any other tools except the special tools, so that the purpose of 100 percent theft prevention can be achieved. The 100 percent anti-theft inspection well cover can be widely mounted and used as an inspection well cover for theft and terrorist destruction prevention of a large number of outdoor underground power or telecom cable inspection wells, or underground sewage pipe inspection wells for municipal facilities, and achieves remarkable social benefits.

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...
