Abstract
The utility model discloses a bridge bearing-type manhole cover combination structure, comprising an upper cover, a cover bridge, and a bridge base. The upper cover and the cover bridge are both mounted on the bridge base. A positioning back-up ring is arranged on the upper cover. The outer diameter of the positioning back-up ring is matched with the inner diameter of the bridge base. Cover bridge positioning slots matched with the cover bridge are arranged on the bridge base. The beneficial effects of the utility model are that the bridge bearing-type manhole cover combination structure is compact in construction and the multi-unit independent members are convenient to use; the cover bridge is a main unit member for enhancing the bearing capability of a manhole cover and the cover bridge connected with the upper cover is substantially improved in anti-compression capability so that the breakage rate of the manhole cover can be reduced; and moreover, the mixed structure unit members can be reduced in manufacture cost and have an antitheft effect.
Description
Technical field
The utility model relates to power supply, communication, combustion gas, sewage, rainwater, tap water etc. more than ten plants a kind of manhole cover combination product of the network pipeline system of cities and towns underground installation, and especially a kind of bridge holds formula manhole cover combining structure.
Background technology
Along with social development in science and technology, China expands rapidly in city, population is concentrated in a large number, and road street gathers, and motor vehicle increases, vehicle flowrate is large, speed is fast, and the situation that vehicle-mounted load is many makes the manhole cover badly broken of urban pavement, and the manhole of damaged disappearance well lid has formed stealthy killer and the trap in city night, sleet sky, greatly affect the driving safety of town dweller's trip and non power driven vehicle, electric vehicle, also affected the overall appearance of the appearance of the city.
Domestic and international produced manhole cover combination product now, its design principle or before more than 100 year, fracture resistence force is learned the plane structure technology of character, to be combined by plane plectane well lid and cage, several centimeters of supports of cage periphery the load passing through on well lid, and population, wagon flow, vehicle load before a century is all less than modern society.
Therefore, the manhole cover breakage of modern city and towns is large, has caused many hazard to person problems, and the product design before a century can not meet the transport development needs in current social cities and towns.
Utility model content
In order to overcome above technical problem, the utility model provides the bridge that a kind of anti-pressure ability is large to hold formula manhole cover combination product, is used for reducing the breakage rate of well lid.
The technical scheme that the utility model solves its technical problem employing is, a kind of bridge holds formula manhole cover combining structure, comprises upper cover, lid bridge and bridge chair, and described upper cover and Gai Qiao are installed on bridge chair, on described, cover and be provided with positioning retainer ring, the external diameter of described positioning retainer ring matches with the internal diameter of bridge chair; Described bridge chair is provided with the lid bridge locating slot matching with Gai Qiao; Described positioning retainer ring is provided with the groove matching with Gai Qiao;
Between described bridge chair and upper cover, pad is set;
Described Gai Qiaoke thinks circular arch bridge, rectangle slab bridge or crux slab bridge;
Described upper cover and lid bridge can be integrated builds molding structure;
Described bridge chair inner side is provided with anti-drop net link, for hanging anti-drop net.
The beneficial effect that the utility model produces is, the utility model compact conformation, multiple-unit individual member is easy to use, Gai Qiao is the formant member that manhole cover is strengthened supporting capacity, lid bridge anti-pressure ability multiplication with upper cover disjunctor, can reduce the breakage rate of manhole cover, combination construction unit member can reduce cost, and has anti-theft effect.
