Abstract
The invention discloses a kind of PVA concrete Vibration-reducing manhole cover, including manhole cover body, well seat and damping component, the well seat is fixed on both ends of the well head along vehicle traveling direction, the well seat includes the carrying bearing of carrying well lid, the damping component is arranged on carrying bearing vertical plane and horizontal plane, the manhole cover body is adapted with the carrying bearing, the manhole cover body is arc arch shape structure, on carrying bearing, the manhole cover body and well seat are PVA reinforced concrete members for the arc arch shape structure and its overhang bracket.Heretofore described manhole cover body uses arc arch shape structure, the vertical stress of well lid and well lid vibration under Vehicle Load can be effectively reduced, further utilize the Compressive Performance of concrete, improve the shock resistance of well lid, ensure the integrality of manhole cover body structure, the accumulated damage that vehicle produces well lid vibration is greatly lowered, while effectively reduces noise effect, possesses good holding and drops effect and permanent effects.
Description
Technical field
The invention belongs to municipal administration and technical field of road engineering, well lid technology more particularly in Municipal Road Engineering.
Background technology
The place of the public utilities such as every installation tap water, sewage, rainwater is required for installation well lid.As China's road is handed over
Logical rapid development, the market usage amount of well lid are huge.Most of existing well lid material for armored concrete, spheroidal graphite casting or
Person's iron member, its material brittleness is big, easy fracture, and judder can occur for trolley especially weight truck traveling, produce noise,
Accumulated damage is easily produced, since stolen phenomenon often occurring with economic value.In practical application, well lid is rolled by vehicle
And breakage or well lid are stolen phenomenon and happen occasionally, cause road and installation security to decline, traffic problems can be caused.
The content of the invention
The present invention provides a kind of PVA concrete Vibration-reducing manhole cover, and the manhole cover body and well seat use PVA armored concrete knots
Structure, and damping component is equipped with, heretofore described manhole cover structure is simple, and can provide the stress performance and impact resistance of well lid
Can, and reduce noise effect.
To solve the above problems, the present invention uses following technical proposals.
A kind of PVA concrete Vibration-reducing manhole cover, including manhole cover body, well seat and damping component, the well seat are fixed on well head
Along the both ends of vehicle traveling direction, the well seat includes the carrying bearing of carrying well lid, and the damping component is arranged on carrying branch
Seat vertical plane and horizontal plane, the manhole cover body are adapted with the bearing that carries, and the manhole cover body is arc arch shape structure, institute
Arc arch shape structure and its overhang bracket are stated on carrying bearing, the manhole cover body and well seat are PVA reinforced concrete members.
Further, the damping component is overlapping rubber component.
Further, the upper surface of the manhole cover body is flushed with the upper surface of well seat.
Beneficial effects of the present invention are：Heretofore described manhole cover body uses arc arch shape structure, can be effectively reduced
The vertical stress of well lid and well lid vibration under Vehicle Load, further using the Compressive Performance of concrete, improve the anti-of well lid
Impact property, ensures the integrality of manhole cover body structure, and arc arch shape structure can reduce the ratio of reinforcement, effectively reduces well lid and is pressurized
Performance, therefore manhole cover body weight can be mitigated, reduce production cost；Manhole cover body uses PVA armored concrete in the present invention
Structure, can effectively improve the cracking resistance and shock resistance of well lid；And heretofore described well lid is provided with damping
Component, is greatly lowered the accumulated damage that vehicle produces well lid vibration, while effectively reduces noise effect, possesses good hold
Effect and permanent effects drop.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of heretofore described PVA concrete Vibration-reducing manhole cover.
Fig. 2 is a kind of top view of heretofore described PVA concrete Vibration-reducing manhole cover.

All connection/connection relations, not singly refer to component and directly connect, and refer to be added deduct by adding according to specific implementation situation
Few couple auxiliary, to form more preferably draw bail.Each technical characteristic in the invention, in not conflicting conflict
Under the premise of can be with combination of interactions.
With reference to Fig. 1, a kind of PVA concrete Vibration-reducing manhole cover, including manhole cover body 2, well seat 1 and damping component 3, the well seat
1 is fixed on both ends of the well head along vehicle traveling direction, and the well seat 1 includes the carrying bearing of carrying well lid, the damping component 3
Carrying bearing vertical plane and horizontal plane are arranged on, the manhole cover body 2 is adapted with the carrying bearing, the manhole cover body 2
For arc arch shape structure, on carrying bearing, the manhole cover body 2 and well seat 1 are PVA for the arc arch shape structure and its overhang bracket
Reinforced concrete member.
Further, the damping component 3 is overlapping rubber component.
Further, the upper surface of the manhole cover body 2 is flushed with the upper surface of well seat 1.
The better embodiment of the present invention is illustrated above, but the invention is not limited to the implementation
Example, those skilled in the art can also make a variety of equivalent modifications on the premise of without prejudice to spirit of the invention or replace
Change, these equivalent modifications or replacement are all contained in the application claim limited range.
