Abstract
The present invention relates to the production method of an under road well or the well cover of the other channels, in particular to an environmental protection well cover and the production method thereof. The main raw materials of the well cover are dilapidated PVC plastic film, non-degradable plastic waste material, fly ash and soil. The dilapidated PVC plastic film and the non-degradable plastic waste material are crushed to pieces, and are added with the soil and the fly ash and put into a frying pan for heating, after being heated, the stuff is put into a pinch refining machine for heating and stirring, after being stirred uniformly, the raw materials of the well cover are filled into a mold and delivered to a suppressing machine for dwelling, finally the product is finished. The well cover adopts the recycled plastic raw material of the soil and the fly ash, thereby, the capability of tensile, anti-pressing and anti-torque of the well cover is further improved, and the national road pressure standard can be reached and surpassed. The well cover has better capability of tensile, anti-pressing, anti-torque and anti-aging, and the production cost is low, and the present invention is more suitable for the road construction.
Description
Technical field
The present invention relates to the well lid making method of well under the road or other pipelines, especially a kind of environmental protection well cover and preparation method thereof.
Prior art
At present, the well lid of well or other pipelines is for environmental protection with prevent loss under the road, gradually be improved to various waste and old plastic goods well lids by metal, concrete product, though adopted these waste and old plastics to play environmental protection, anti-lost effect, but because the resistance to compression of plastic cement and antitorque poor apart from performance, be difficult to reach national road pressure standard, long wind and weather of process and vehicle rolling again, be easy to aging and damage, cause unnecessary trouble on the contrary the Facilities Construction of road, also increased the cost of Road construction.
Summary of the invention
Goal of the invention of the present invention is: adopt various waste and old can with separate with nondegradable plastic garbage grinding and processing after add a certain proportion of soil again and flyash is made into a kind of more environmental protection well lid cheaply; Not only environmental protection but also the resistance to compression, anti-aging of this well lid, production cost is low; To achieve these goals, a kind of environmental protection well cover of the present invention and preparation method thereof is achieved in that a kind of environmental protection well cover, its starting material be by: shabby PVC plastics film, nondegradable plastic garbage material, flyash and soil process, and its ratio is: shabby PVC plastics film accounts for 59%---45%, nondegradable plastic garbage material accounts for 10%---24%, flyash---6%, soil account for 5%---25% that accounts for 26%; At first, shabby PVC plastics film 55% and nondegradable plastic garbage material 14% are ground into fragment, add flyash 10% and soil 21% again and be sent to frying pan and heat, temperature is warmed to 150 ℃; Well lid raw material after will heating is then delivered in the milling machine and is stirred, and temperature is controlled in 205 ℃; Begin discharging when stirring postcooling to 120 ℃, the well lid raw material that comes out in the milling machine is inserted mould send on stamper, adopt 280 tons pressure pressurize 15-30 minutes; Be cooled to the finished product of environmental protection well cover at last.It is shabby PVC plastics film, nondegradable plastic garbage material and flyash that this well lid adopts the plastic raw materials that reclaims, and has improved the pull resistance of well lid, has also reduced the pollution of environment; Soil not only do not have cost but also and the mixing of flyash more increased resistance to compression, the anti-twisting property of well lid, can reach and surmount national road pressure standard; So the more resistance to compression of this environmental protection well cover, tension, antitorque distance and anti-aging, production cost is low; More be applicable to the use of Road construction.
Embodiment
Below the present invention is described further: a kind of environmental protection well cover, its starting material be by: shabby PVC plastics film, nondegradable plastic garbage material, flyash and soil process; Shabby PVC plastics film 55% and the nondegradable plastic garbage material 14% retrieved are ground into fragment, and the flyash 10% that adds soil 21% and recovery again is sent to frying pan and heats, and temperature is warmed in 150 ℃; Well lid raw material after will heating is then delivered in the milling machine and is stirred, and temperature is controlled in 205 ℃; Begin discharging when stirring postcooling to 120 ℃, the well lid raw material that comes out in the milling machine is inserted mould send on stamper, adopt 280 tons pressure pressurize 15-30 minutes; Be cooled to the finished product of environmental protection well cover at last.
