Description
Technical field
The utility model belongs to the lid of manhole shaft or the like, is related to a kind of manhole cover.The utility model is checked
Well lid is widely portable to needed for the municipal works public utility such as running water, telecommunications, electric power, combustion gas, heating power, fire-fighting, environmental sanitation
Manhole cover, is also applied for urban road, highway, motor vehicles traveling or passage, the place inspection shaft parked.
Background technology
With developing rapidly for China's road traffic cause, modernization, high-grade urban road increasingly increase, city road
Road Buried Pipeline Network Systems increase therewith, well lid（That is manhole cover）It is the closure led at the top of the gateway of underground installation, it is all
It is that the place for installing the public utilities such as running water, telecommunications, electric, combustion gas, heating power, fire-fighting, environmental sanitation is required for installing well lid, market
Demand is huge.
In the prior art, manhole cover includes well lid and well seat, and the type of manhole cover mainly has cast iron（Spheroidal graphite cast-iron and
Grey cast-iron）Well lid, steel fibre concrete manhole and polymer base composite well lid.The well lid that tradition is used mostly cast iron well
Lid, casting iron well lid intensity is high, easy to use, but iron consumption amount is big, cost is higher, and material fragility easily causes phenomenon of rupture, and casts
Iron well lid is easily stolen because itself having recovery value, it is serious to lose, and the powerless control of City supervision not only causes huge to country
Big economic loss, is also easy to the severe safety hazards for causing the walking along the street because of manhole cover loss to pedestrian and vehicle to constitute safely, holds
Easily cause various accidents.The steel fibre concrete manhole and polymer matrix composite of follow-up developments（Resin and fiberglass）Well
Lid, because it does not possess recovery value substantially, all overcomes stolen phenomenon.But steel fibre reinforced concrete well lid strength character
Not enough, it is necessary to larger thickness（＞ 10cm）Can be only achieved GB26537《Fabric reinforcement concrete manhole cover》D400 class requirements
Bearing capacity, well lid weight is very big.Polymer base composite well lid service life is shorter, frequently bear dynamic load impact and
Exposed to extraneous natural conditions, easy generating material ageing failure influences service life.These shortcomings make steel fibre concrete manhole
Being covered with polymer base composite well can not meet needs in the case where city major commuter flow is larger, only can be used in people
Trade, bicycle lane etc. receive the less situation of dynamic load, are only limitted to make the manhole cover of C250 and level below.Existing skill
Also as using complicated curved-surface structure or honeycomb, there is the defects such as shaping difficulty is big, batch production cost is high in art well lid.
The content of the invention
The purpose of this utility model is intended to overcome deficiency of the prior art, there is provided a kind of manhole cover.The utility model
