Abstract
The present invention discloses two anti-theft composite manhole cover plates and processing technologies thereof. The cover plates are processed by mixing plastics, steel and wood materials, and have the advantages of light weight, high durability, impact resistance and corrosion resistance. The cover plates need to be opened by special opening tools, and an anti-theft purpose is truly achieved.
Description
Technical field
The present invention relates to a kind of anti-stealing manhole cover plate, particularly a kind of with waste plastic and the disposable chopsticks of recovery or the anti-stealing manhole cover plate of waste plastic and disposable bamboo chopsticks produced with combination, belong to manhole shaft overburden and this obducent processing technology thereof of road communal facility network of underground.
Background technology
Existing cover plate of manhole mostly is cast iron and makes, and covers on the walling crib.Constructor such as need are checked underground installation, start well lid and go down just more convenient.Open easily again just because of well lid is an irony, also just provide the chance of committing theft, the thief is often taken place the inspection shaft lid is stolen, smashed, be used as scrap iron and dispose of stolen goods to the thief.This not only causes loss economically, also takes place often because of lacking the inspection shaft lid, and is injured in night pedestrian's back drop, even the tragedy that the child falls into the drowned death of inspection shaft takes place!
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art; provide a kind of simple in structure, durable in use; the anti-stealing manhole cover plate of protection people's life safety; the refuse that abandons after again people being used in daily life simultaneously; disposable wood or the bamboo chopsticks bigger as polybag, film, bottle and the amount of expending are processed into the method for composite material manhole cover plate.
Above-mentioned purpose is achieved in that moulds this or moulds bamboo combined anti-theft cover plate of manhole, there are taper hole and up big and down small circular cone to mould wood or mould the bamboo reinforcement composite decking by the center, cover plate is put upside down from beginning to end by waste wood chopsticks or useless bamboo chopstick and is arranged in parallel within on the plastic disc, on cover plastic disc, heating, add and be pressed into Layer cake, and after multilayer stacked fusion hot pressing, the flange with the steel taper hole pipe that matches was formed by connecting with screw again.Its processing technology with waste plastics bag, film and the bottle of reclaim cleaning, is put into baking oven, be heated to 200 ℃ and make it to soften into the molten mass shape, and pressurization extrudes from container bottom, again through rolling into about one centimeter thick plastic sheet, and is cut into discoid; Again the waste wood chopsticks of reclaiming or useless bamboo chopsticks are put upside down from beginning to end and be arranged in parallel within on the plastic disc, and the end can suitably interlock, on cover a plastic disc, again this Layer cake is heated, pressurize, make it fusion and synthesize an integral body.Again with a plurality of Layer cake by wooden chopsticks or bamboo chopsticks are interleaved stacks, each aspect is smeared bonding agent, puts into mold cavity again, adds 10kg/cm on die cavity top
2Pressure, energising simultaneously is heated to 200 ℃, makes that the outer rim of plastics Layer cake is softening to be the molten mass shape, clamp-ons in the die cavity of cover plate outer rim, has a power failure, logical cooling water temperature makes cover plate be cooled to the cone shape similar to die cavity around die cavity.The taper hole at machining cover plate center is wrapped up in one deck plastic sheet on steel Taper Pipe with matching again, packs in the taper hole of cover plate center, puts into heating wire in the steel Taper Pipe, and energising is heated to 200 ℃, makes the softening and integrator of material fusion on every side of plastic sheet.Cast steel flange with the taper pore links into an integrated entity with screw and cover plate center taper hole then.Also available thin wood or bamboo row culture muscle in the Layer cake
Thisly mould wood or mould bamboo combined anti-theft cover plate of manhole, be skillfully constructed, novel structure, the polybag that people are discarded, film and wood (bamboo) chopsticks etc. fully utilize again, both solved environmental pollution problems, lightly durable again, shock resistance, corrosion-resistant, opening needs to use special tool, has fundamentally solved antitheft problem.And its processing technology is uncomplicated, and cost is low, very easily applies.
Description of drawings
Fig. 1 is the structural representation of moulding wood or moulding bamboo combined anti-theft cover plate of manhole
Fig. 2 is the processing process schematic diagram of moulding wood or moulding bamboo combined anti-theft cover plate of manhole
Mould wood or mould bamboo combined anti-theft cover plate of manhole, by the center taper hole and up big and down small conical composite material cover plate 1 are arranged, cover plate is put upside down from beginning to end by waste wood chopsticks or useless bamboo chopstick and is arranged in parallel within on the plastic disc, on cover plastic disc, heating, add and be pressed into Layer cake, and after multilayer stacks fusion hot pressing, be formed by connecting with the flange 2 usefulness screws 3 of the steel tapered hole pipe that matches again.This antitheft composite cover plate of manhole processing method is, discarded polybag, film and the bottle of cleaning put into baking oven, be heated to 200 ℃ and make it to soften into the molten mass shape, and pressurization is extruded from container bottom, again through rolling, and be cut into discoid into about one centimeter thick plastic sheet; Thereafter the waste wood chopsticks of reclaiming or useless bamboo chopsticks are put upside down from beginning to end and be arranged in parallel within on the plastic disc, and the end can suitably interlock, on cover a plastic disc, again this Layer cake is heated, pressurize, make it fusion and synthesize an integral body.Again with a plurality of Layer cake by wooden chopsticks or bamboo chopsticks are interleaved stacks, each aspect is smeared bonding agent, puts into mold cavity again, adds 10kg/cm on die cavity top
2Pressure, energising simultaneously is heated to 200 ℃, makes that the outer rim of plastics Layer cake is softening to be the molten mass shape, clamp-ons in the die cavity of cover plate outer rim, has a power failure, logical cooling water temperature makes cover plate 1 be cooled to the cone shape similar to die cavity around die cavity.The taper hole at machining cover plate center again, on steel Taper Pipe with matching, wrap up in one deck plastic sheet, pack in the taper hole of cover plate center, in the steel Taper Pipe, put into heating wire, energising is heated to 200 ℃, make the softening and integrator of material fusion on every side of plastic sheet, prevent that rainwater from infiltrating wooden muscle of corrosion or bamboo reinforcement.Then the cast steel flange 2 usefulness screws 3 of taper pore are connected into cover plate 1 center taper hole and mould wood or mould bamboo combined anti-theft cover plate of manhole.Also available thin wood or bamboo row culture muscle in the Layer cake.
