Problems solved by technology
[0002] At present, the inspection well cover and the cover seat are generally connected with screws or pins. Because the screws are easy to unscrew and the clips of the pins are easy to take off, the inspection well cover is easy to be stolen; When spraying water outwards, the manhole cover is easily washed away by the sprayed water, and it becomes a trap because it cannot automatically warn passers-by

The invention relates to a manhole cover with a fence. The manhole cover comprises a manhole cover base and a manhole cover plate, the manhole cover is characterized in that an inwards-protruding annular table is arranged on the inner side wall of the middle portion of the manhole cover base, a plurality of vertical holes are formed in the annular table, a fence column is arranged in each verticalhole, the upper ends of the fence columns are fixed to the manhole cover plate, and the lower ends of the fence columns are provided with anti-retreating combined pins; and automobile reflective stickers are pasted on the peripheries of the fence columns and the manhole cover plate, and each fence column has outward elasticity. According to the manhole cover manufactured through the technical scheme, the manhole cover plate and the manhole cover base cannot be separated, and therefore a theft cannot steal the manhole cover plate by pulling down the anti-retreating combined pins, and the performance of prevention of thievery is good.
Description
technical field [0001] The invention relates to a manhole cover with a fence. Background technique [0002] At present, the inspection well cover and the cover seat are generally connected with screws or pins. Because the screws are easy to unscrew and the clips of the pins are easy to take off, the inspection well cover is easy to be stolen; When spraying water outwards, the manhole cover is easily washed away by the sprayed water flow, and becomes a trap because of not being able to automatically warn passers-by. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a manhole cover with a fence, which can effectively overcome the above-mentioned shortcomings. [0004] The technical solution adopted by this invention is a inspection shaft cover with a fence, which includes an inspection shaft cover seat and an inspection shaft cover plate. There are several vertical holes on the platform, and there is a fence post i...
