Description
Technical field
The utility model relates to a kind of road inspection well well lid, specifically, relates to a kind of steel plate-steel fibre manhole well lid.
Background technology
At present, on China's town road, use amount at most, what be most widely used is casting iron well lid, also the advantage of its self uniqueness is had: the advantages such as supporting capacity is high, anti-wear performance is strong, fitting operation is convenient as traditional manhole cover, the characteristic that its supporting capacity is high is that not available for other material type well lid product, this is also the major reason that casting iron well lid can be used till today.
But along with a large amount of consumption environment pollution of resource and the requirement of people to quality of life improve constantly, the manhole cover needing research and development more can meet society need goes to replace traditional casting iron well lid, and casting iron well lid also also exists many shortcomings:
1. manufacturing cost is high, and the price of the huge iron and steel of current resource consumption also day by day goes up and causes the manufacturing cost of castiron well cover to improve;
2. noise pollution, the automobile galloped at all speed rolls well lid, makes well lid side edge thereof form noise effect resident and have a rest with supporting to produce to collide;
3. corrosion resistance is poor, is subject to rain erosion vehicle and rolls casting iron well lid, corrosion phenomena easily occurs at preformed hole place and open place and causes overhauling and open difficulty;
4. well lid is lost, and due to its recovery value, high a lot of law-breaker steals casting iron well lid;
5. easily overturn, frangible, casting iron well lid, due to its lighter weight, when vehicle flowrate is intensive easily broken by bundle, easily overturns when running into the high wagon flow of travel speed and causes serious traffic accident.
Wherein the most serious is exactly the loss problem of manhole cover, because the casting iron well lid ordered about on road by interests is often stolen, the lighter cause economic loss serious cause the people's lives and property to lose initiation road traffic accident, the town road in a lot of area, the whole nation all occurred, " black hole " phenomenon that various castiron well cover is lost, become a stain on urban road, this is also incompatible with construction modern civilization society, what is more important well lid " black hole " problem brings inconvenience to the road operation in city, potential safety hazard is brought to the life of the people.
Utility model content
The purpose of this utility model is to provide a kind of steel plate-steel fibre manhole well lid, has stronger bearing capacity, effectively reduces well lid sectional dimension and weight.
The technical solution of the utility model is: steel plate-steel fibre manhole well lid, it is characterized in that: this well lid mainly comprises steel plate, steel fibrous concrete and shear connector, described steel fibrous concrete adopts steel fibrous concrete, full parcel steel plate or portion envelops steel plate bottom described steel fibrous concrete, described steel plate is fixed by the steel fibrous concrete on shear connector and top, and described shear connector adopts melting welding mode to be connected with described steel plate contact site.
Full steel plate is wrapped up bottom described steel fibrous concrete, namely steel plate is set up in the bottom of this well lid and both sides, described shear connector is fixed on bottom and the both sides of steel plate, and the shear connector bottom described steel plate is equidistantly arranged, the shear connector of described steel plate both sides is arranged in both sides steel plate opposite position.
Described steel fibrous concrete base section parcel steel plate, namely set up steel plate in the bottom of this well lid, described shear connector is fixed on the bottom of steel plate, and the shear connector bottom described steel plate is by equidistantly arrangement.
This well lid described is round manhole cover, and the cross section of well lid is trapezium structure.
Described shear connector adopts perforate screw thread peg, and described perforate screw thread peg adopts melting welding mode to be connected with described steel plate contact site.
The utility model beneficial effect is compared with prior art:
(1) antitheft: compared with casting iron well lid, this well lid main body is made up of the non-metallic material of steel fibrous concrete, and recycling is worth low and cost is low, and therefore pilferage rate is low, and non-metallic material also has the advantage of not corroding and polluting for only time;
(2) supporting capacity is strong: steel fibrous concrete material has stronger bending and tensile strength, and sets up shear connector steel fibrous concrete that is steel plate is overall and top and form a stressed entirety, the bearing capacity of increase well lid;
(3) noise pollution is little: relative to metal material, and weight and the rigidity of steel fibrous concrete material are less, therefore produces less noise with the supporting surface place of colliding.
