Description
Technical field
The utility model relates to a kind of airproof deodorization blind shaft cover.
Background technology
The important technological parameters of well lid is: technical data test load: heavy 400KN, general type 250KN, light-duty 125KN, bending strength: average 22MPa impact strength: average 10J/m2, compressive strength: average 25MPa, hot strength: average 10MPa, modulus of elasticity: average 1000MPa, water absorption rate: 1%, acid resistance: sample is 20%, soak 48h in sulfuric acid solution, surface is corrosion-free, mass loss 1%.Mainly contain following technical characterstic 1, intensity is high: magnesite inspection, there is very high resistance to compression, bending resistance, shock proof intensity, flexible.After Long-Time Service this product there will not be well lid crushed and damage phenomenon, thoroughly can stop the generation of " black hole, city " accident.2, outward appearance is beautiful: the design of magnesite manhole cover surface detail is exquisite, and color is beautiful adjustable, beautifying urban environment.3, easy to use, lightweight: product weight is only about 1/3rd of cast iron, be convenient to transport, install, rush to repair, significantly reduce labour intensity.4, antitheft: magnesite manhole cover is without recovery value, naturally antitheft; Need according to client and be provided with latch-up structure, realizing property in well antitheft.5, weatherability is strong: magnesite manhole cover makes this product normally can use in-50 DEG C ~+300 DEG C environment by the formula of science, advanced technique, perfect technical equipment.6, acid and alkali-resistance, corrosion-resistant, wear-resisting, resistance to vehicle roll, long service life.Well lid is distinguished by material can be divided into 4 classes: A. metal well lid: cast iron, ductile iron, bronze well lid etc.; B. high-strength steel fiber cement concrete well lid (cement-base composite material); C. regenerating resin well lid (regenerating resin based composites); D. polymer-base composite material cover for inspection manhole etc.Wherein the well lid of composite is divided into inorganic compounding well lid and organic composite well lid two kinds.Steel fiber concrete manhole cover is divided into a, b, c, d level Four by supporting capacity: a level steel fiber concrete manhole cover, for extraordinary road and places such as airports.B level steel fiber concrete manhole cover, for motor-driven vehicle going, the urban road parked, highway and parking lot.C level steel fiber concrete manhole cover, for slow lane, esidential building community internal channel and sidewalk.D level steel fiber concrete manhole cover, the lane of can not travel for greenbelt and motor vehicles, parking and place.Generally be divided into circular and square by shape differentiation.In the road administration in urban district, generally adopt circle, because the well lid of circle not easily tilts, the safety of pedestrian and vehicle can be protected preferably.Utilize with cable shaft in the country, general adopt square, like this can the entering of the liquid such as pre-rainwater-proof better.
Have a variety of in the national standard of Chinese well lid, individual layer, double-deck, cast iron, ductile iron, compound, cement, magnesite etc.According to the newest standards requirement of national newest standards GB/T 23858-2009, well lid weight bearing power can be divided into following several: wherein have and a bit illustrate, well lid weight bearing power and well lid are not concepts by the ability of vehicle.Well lid weight bearing power refers to, in unit area, carries out pressure test by pressure testing machine, heavy 40 tons usually.And if by car, 5 axle heavy load truck design formulas: 5 axle x40 ton=200 ton.Under automobile gross weight 200T tonnage, this heavy well cover can ensure to pass through.And some producer said the technical data of 80 tons of vehicles, if divided by 5 axles, so well lid load of going out of its our factory: 80t/5=16t, this just illustrates, the own load of well lid just 16 tons.According to GB/T23858-2009 " manhole cover " the 4th regulation, well lid is divided into six grades according to supporting capacity: first group: (the minimum A15 of selecting level type): the region that motor vehicles sail into is forbidden on greenbelt, sidewalk etc.Second group: (minimum select B125 type): sidewalk, bicycle, dolly parking lot and underground parking.3rd group: (the minimum C250 of selecting type): residential quarters, back street lane, the region that only has light-duty vehicle or dolly to travel, road is on both sides of the road in road kerb 0.5m.4th group: (minimum select D400 type): the regions such as city thoroughfare, highway, speedway.5th group: (minimum select E600 type): the regions such as freight terminal, harbour, airport.6th group: (minimum select F900 type): the regions such as airfield runway.
Nippon Standard.Engineering level was in 1958, and Japan makes the well lid compulsory standard of regulation to key indexs such as well lid thickness, material, load-bearing.Existing Industry code requirements well lid must be cast with the ductile iron of high strength, and thickness is more than 17 centimetres, and weight need reach 40 kilograms.Japanese Terrestrial well lid industry meeting affairs office chief keeps room health and represents, the well cover for sewer that Japan is all, through the inspection of quality of the industry mechanisms such as Japanese sewer association.After securing permission, just can dispatch from the factory.Annual afterwards also have regular quality examination, ensures well lid quality by such oversight mechanism.
Laminating standard, in China, not tightly, when vehicle presses through, tire meeting and well lid produce collision, and well lid is one of noise source becoming city therefore for most of well lid and road surface laminating.At 20 century 70s, many japanese peoples, deeply by the hardship of well lid noise, to claim solution " noisy well lid " to local government one after another.Japanese government revises the standard of well cover for sewer immediately, changes columniform well lid into up big and down small conical well lid, and requires that well lid casting must be accurate to millimeter.So, can fit in well lid and road surface with fitting together perfectly, both stopped noise, too increase the difficulty of stealing well lid.
Safety problem, 2010, Kochi County, Japan suddenly rained cats and dogs, and caused part well cover for sewer to come off or breakage, caused multidigit pedestrian to fall sewer.Japan's Homeland Security is economized and is convened expert and local government to set up " the Sewage well cover emergency safety countermeasure committee " immediately, carries out on-site inspection to the sewer scene of the problem of generation.Investigation has found that 8 classes need the well lid safety problem solved, and has worked out corresponding " Sewage well cover emergency safety countermeasure " according to the principle of " locking deathtrap, delimit danger classes, thoroughly eliminate safe hidden trouble according to danger classes and existing force ".Specifically comprise changing and separate pressure type dropproof well lid, set up camera monitor well lid state, ladder is set in sewer is escaped danger to fall pedestrian, set up Sewage well cover information and damage monitoring system etc.
The research and development of the immortal steel well lid of China and the combined manhole cover goods that appear on the market, substantially all carry out according to following three kinds of technology paths: (1) magnesite material well lid (FRIM well lid); (2) glass fiber reinforced plastic/stainless steel material hand sticks with paste well lid; (3) BMC moulding compound well lid.
