Abstract
The utility model relates to a manhole cover used in municipal construction, particularly a modified plastic antitheft manhole cover. The modified plastic antitheft cover for the manhole mainly solves pedestrians and vehicular safety accidents which are induced by lawbreaker's stealing of the existing manhole cover. The utility model comprises a manhole cover of which the inner part is inlaid with metal reinforcing ribs, and a manhole cover base. The utility model is characterized in that the manhole cover is matched with the manhole cover base in a bellmouthing gradual-contraction type structure. The bottom of the manhole cover is provided with a plurality of circular hole-shaped convex reinforcing ribs. The utility model adopts the modified plastic without recovery and utilization value, and can avoid the theft phenomenon. The utility model has the advantages of light weight, high strength, convenient installation, sealing connection and stability.
Description
Technical field
The utility model relates to the inspection shaft lid that urban construction is used.
Background technology
Engineerings such as the water supply and draining in the urban construction, communication, heating and pipe natural gas all will be used the inspection shaft lid, have the inspection shaft lid now owing to be to adopt iron material to make with the value recycled, the pedestrian that causes because of lawless person theft and the security incident of vehicle usually take place, and often cause the serious consequence that is difficult to retrieve.
Summary of the invention
The purpose of this utility model provide a kind of in light weight, intensity is high, simple installation, connection sealing, steadily and not have and recycle the modified plastics anti-stealing manhole cover that is worth.
The utility model is achieved in that and comprises that inside is embedded with the well lid and the manhole cover base of metal reinforcing, it is characterized in that between said well lid and the manhole cover base for horn mouth gradually the compact form structure match, several circle hole shape convex reinforcing ribs are arranged at the bottom of well lid.
The extension of above-mentioned manhole cover base bottom is convenient to the outstanding circle that is connected with the well body in addition.
Said several circle hole shape convex reinforcing ribs are distributed on the bottom of well lid, and the upper surface of well lid has the anti-skidding line of arbitrary shape, and well lid also has drainage hole, and manhole cover base top is arc-shaped surface with the seam of giving prominence between the circle that is connected.
The utility model adopts gradually compact form structure of horn mouth, make the sealing that is connected between well lid and the manhole cover base, steadily, well lid can not take place to slide, flop phenomenon, guarantee safe in utilization, especially to sewage, addle pipeline and septic tank etc. have located to prevent significantly the air pollution effect, several uniform circle hole shape convex reinforcing ribs of well lid bottom can transmit dispersive pressure equably, prevent that stress is concentrated, make well lid be difficult for being damaged, long service life, the inside of well lid and manhole cover base is embedded with metal reinforcing, can improve the intensity of well lid and manhole cover base, particularly adopting the modified plastics that does not have the value recycled is raw material, not only can make the in light weight of well lid and manhole cover base, and the generation that can avoid stealing phenomenon, the safety of guarantee pedestrian and vehicle.
