Abstract
The utility model relates to a carbon fiber composite shock-absorbing well cover. A cover body of the well cover disclosed by the utility model comprises at least a layer of upper carbon fiber fabric and at least a layer of lower carbon fiber fabric, wherein multiple carbon fiber composite rod reinforcing bar layers are wrapped between the carbon fiber fabrics, epoxy resin mixed packing is filled among reinforcing bars, and a rubber gasket is arranged at a part at the edge of the cover body and contacted with a well seat. Besides meeting the shortcomings of common well covers, the well cover disclosed by the utility model also has the advantages of high strength, good environmental aging resistance, wear resistance, creep resistance, high safety and stability, long service life, and the like, and can effectively solve the theft-proof problem of well covers. Besides satisfying the daily life use, the well cover also can be widely applied to the road sections such as airports, ports and piers and the like which are high in traffic flow and high in load, and the well cover is applicable to areas with relatively severe environments such as humid environments and the like.
Description
Technical field
The utility model belongs to municipal pipeline construction project field, and particularly a kind of carbon fibre composite shock-absorbing well cover, this product are applicable to the highway section that the vehicle flowrates such as airport, port and pier are large, the load-carrying load is high; Transformer station, chemical plant, Gas Pipe road junction and the more abominable area of environment such as have a humid climate.
Background technology
For a long time, the manhole cover that the public utility of China is used generally adopts Cast Iron Production, and its material limitation and power consumption of polymer processing, environment pollution etc. bring puzzlement for engineering, environment, the energy.Particularly the problem of losing of well lid never well solves, and often causes communications and transportation, personal safety accident, affects the urban economy construction, and social environment is had a negative impact.
The well lid that uses at present has following several: casting iron well lid, cement well lid, composite drain cover etc.Casting iron well lid is easily stolen, and noise is large, affects resident's life; Cement well lid is heavy, opens difficulty, give construction and maintenance make troubles and supporting capacity inadequate; The recycled plastics manhole cover in use, especially vehicle constantly rolls in the higher situation of temperature, creep can occur in well lid, causes the well lid middle part constantly to sink, and very causes to come off, and can produce very large potential safety hazard.Use now well lid all to have certain application restric-tion.
The utility model content
The purpose of this utility model is exactly the deficiency for present all kinds of well lids, and a kind of carbon fibre composite shock-absorbing well cover is provided, and it is rational in infrastructure, and intensity is high, long service life.
For achieving the above object, the utility model adopts following technical scheme:
A kind of carbon fibre composite shock-absorbing well cover, it comprises lid, described lid comprises upper and lower each one deck carbon cloth at least, wrapped multiple reinforcing rib layer between carbon cloth, every layer of reinforcing rib layer includes some parallel carbon fibre composite bars, and the carbon fibre composite bar places the mixed with resin filler and is compacted; Edge and well seated connection synapsis at lid are provided with rubber washer.
The carbon fiber of described lower floor is furnished with multilayer, and its quantity is more than the carbon cloth quantity on upper strata.
Described epoxy resin mixed fillers is at least a or several mixture in epoxy resin, chopped carbon fiber, rubber grain, quartz sand, glass fabric and the cotton gauze.
A kind of preparation method of carbon fibre composite shock-absorbing well cover, its preparation technology is as follows:
(1) make the lid mould according to designing requirement, material is metal;
(2) take the carbon fibre composite bar as reinforcing rib; Take 100 parts of normal-temperature curing epoxy resins as matrix, mixing 2 parts of chopped carbon fibers, 20 parts of rubber grains, 30 parts of quartz sands, 3 parts of glass fabrics, 2 parts of cotton gauzes is reinforcing material, makes the epoxy resin mixed fillers after fully mixing;
(3) in mould, lay carbon cloth, the epoxy resin mixed fillers evenly is laid on the carbon cloth by certain thickness, and the carbon fibre composite bar is embedded in wherein compacting as reinforcing rib, and repave the compacting of one deck filler; Repetitive operation, and make second layer reinforcing rib direction and first floor be 90 angles; Spread carbon cloth after compacting, the pressing, apply certain load and compress; Place 24 hours complete to epoxy resin cure;
(4) paste rubber pad at the well lid lower plane outside one circle after the demoulding, cut, repair, reach designing requirement.
High-performance carbon fibre composite material shock-absorbing well cover internal construction of the present utility model has been carried out unique Jia Qiang Zhu design, selecting the carbon fibre composite bar is support frame, arrange with the right-angled intersection form, strengthen blending epoxies with various fillers such as chopped carbon fibers around it and fill, guarantee simultaneously that pole stock evenly distributes and with strengthen matrix close contact, compacting; The well lid upper and lower surface coats with the multilayer carbon cloth; The bottom thickening is processed, to improve the product bulk strength; Well lid edge and well seated connection synapsis sticking rubber packing ring are to improve the shock resistance of goods.
The beneficial effects of the utility model are: structure design is unique, the advantages such as intensity is high, anti-environmental aging performance is good, wear-resisting, the creep resistant security and stability high, life-span length are more arranged except the deficiency that satisfies well lid commonly used, can satisfy daily life and under various harsh environment, use, and can effectively solve the manhole cover anti-theft problem.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the lateral plan of Fig. 1.
Wherein, 1. rubber washer, 2. reinforcing rib layer, 3. carbon cloth, 4. mixed with resin filler, 5. well lid open hole.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Among Fig. 1, Fig. 2, lid comprises upper and lower each two-layer carbon cloth 3, at 3 wrapped multiple reinforcing ribs of carbon cloth layer 2, every layer of reinforcing rib layer 2 includes some parallel carbon fibre composite bars, gap between reinforcing rib has mixed with resin filler 4 to fill, and the carbon fibre composite bar places epoxy resin and filler and is compacted; Edge and well seated connection synapsis at lid are provided with rubber washer 1; Well lid is provided with two well lid open holes 5, is convenient to take out or open well lid.
The carbon cloth 3 of described lower floor has multilayer, and its quantity is more than the carbon cloth quantity on upper strata.
Described mixed with resin filler is the mixture of at least a or several and epoxy resin in chopped carbon fiber, rubber grain, quartz sand, glass fabric and the cotton gauze, play the effect of bonding reinforcing rib, various fillers are used for improving abrasion resistance, creep resistance and the aging of well lid simultaneously.
The mode that the utility model adopts compression molding and hand pasting forming to combine is finished whole manufacture process.At first make the mould of corresponding size, then in die cavity, sprawl carbon cloth, the reinforcing rib of arranging, potting resin mixed fillers, repave the exhibition carbon cloth, apply certain load compacting, place after 24 hours the demoulding and carry out following process, touch the position at bottom outside well lid and well seated connection at last and paste one deck yielding rubber pad.Specific implementation process is as follows:
Embodiment 1
