Abstract
The invention discloses a nodular cast iron and steel fiber well grate which is manufactured by combined processing of an integrated nodular cast iron well grate skeleton and steel fiber reinforced concrete. A cohesive force is very high after pouring is conducted on the steel fiber reinforced concrete and the integrated nodular cast iron well grate skeleton; the integrated nodular cast iron well grate skeleton is arranged in a steel fiber reinforced concrete well grate, and wrapped with the steel fiber reinforced concrete; the edge of a well mouth of the well grate is wrapped with an integrated nodular cast iron well grate skeleton frame; and the overall strength of the well grate is ensured effectively. The nodular cast iron and steel fiber well grate has the characteristics of high overall strength, high bearing capacity, good stability and fatigue resistance, reliability in use, long life, low price and the like; an appearance of the nodular cast iron and steel fiber well grate is similar to a cement product; the nodular cast iron and steel fiber well grate has no recycling value after being recovered; and therefore, theft is not required to be worried, and the nodular cast iron and steel fiber well grate is an ideal updating product that eliminates a city trap and renews the well grates made of other materials.
Description
Technical field
The present invention relates to a kind of well to comb, is specifically a kind ofly combine by spheroidal graphite cast iron integral type well comb skeleton and Steel Fiber Reinforced Concrete the well prepared and comb.
Background technology
At present, the cast iron well that avenue, highway use is combed, and Loss is very general, the well comb insufficient strength of other material, and damage very serious, bring great potential safety hazard to the vehicle of trip and pedestrian, the situation that tumble injury disables happens occasionally.
Summary of the invention
Therefore, people comb to antitheft, that bearing pressure is large well and there is great demand, up to now, also do not find about relevant report of the present invention, the present inventor is through a large amount of research trials, finally successfully develop the antitheft well prepared by spheroidal graphite cast iron integral type well comb skeleton and Steel Fiber Reinforced Concrete to comb, thus complete the present invention.
The antitheft well that object of the present invention is just to provide supporting capacity prepared by a kind of spheroidal graphite cast iron integral type well comb skeleton and Steel Fiber Reinforced Concrete large is combed.
Another object of the present invention there is provided the preparation method that this well is combed.
The solution of the present invention comprises spheroidal graphite cast iron integral type well comb skeleton and Steel Fiber Reinforced Concrete raw material, Steel Fiber Reinforced Concrete raw material is by steel fiber, cement, sand and rubble composition, its constructional feature is first by steel fiber, cement, sand, rubble makes Steel Fiber Reinforced Concrete material, again Steel Fiber Reinforced Concrete material and spheroidal graphite cast iron integral type well comb skeleton mould are carried out Combined machining to make, wherein steel fiber (commercially available) is a kind of steel, filament type material, it can increase the cohesive force of steel fiber and sand-cement slurry, the bulk strength of Concrete Structure, make its anti-folding, resistance to compression, cracking resistance, abrasive wear resistance significantly improves.Spheroidal graphite cast iron integral type well comb skeleton is the novel product of technical research of adopting new technology, and material is close to steel after nodularization leaching thermal treatment for the molten iron of fusing, and inexpensive, have aesthetic in appearance, durable in use, intensity is high, lightweight, uses economic feature.Spheroidal graphite cast iron integral type well comb skeleton is set in Steel Fiber Reinforced Concrete well is combed, well is combed skeleton parcel with Steel Fiber Reinforced Concrete, skeleton is enclosed in concrete layer, makes skeleton and air exclusion, never corrosion.Steel Fiber Reinforced Concrete and spheroidal graphite cast iron integral type well comb skeleton combine that to solidify rear bonding force very strong, long service life, spheroidal graphite cast iron integral type well comb skeleton is wrapped up by Steel Fiber Reinforced Concrete, concrete edge in well comb is along being wrapped up by spheroidal graphite cast iron integral type well comb skeleton frame, effectively ensure that the bulk strength that well is combed, supporting capacity is large, and stability, anti-fatigue performance are good.Well can be combed and is made to circle, square or rectangular shape by the present invention as required.
The raw material dosage of Steel Fiber Reinforced Concrete material of the present invention is also that contriver draws through a large amount of developments and test repeatedly, and the consumption of each raw material all has good effect within the scope of following weight.
Steel fiber 0.5-3kg cement 10-20kg sand 10-30kg
1, rubble 10-35kg water 2-4kg spheroidal graphite cast iron integral type well comb skeleton

Embodiment
Preparation process of the present invention
1, first by cement 10-20kg, sand 10-30kg, rubble 10-35kg siccative adds stirrer and stirs;
2, after being stirred by siccative, then add steel fiber 0.5-3kg, then stir;
3, after stirring, then add water 2-4kg, stir 5-10 minute, obtain Steel Fiber Reinforced Concrete material;
4, mould is placed on the vibration platen of bobbing machine upper end, again the spheroidal graphite cast iron integral type well comb skeleton cast is put into mould, Steel Fiber Reinforced Concrete material is inserted in the mould that spheroidal graphite cast iron integral type well comb skeleton is housed, through shaking table panel vibration 1-3 minute, after shaping, again printing pattern, manually receive light, the demoulding.
It is high that the present invention has bulk strength, and supporting capacity is large, and stability, anti-fatigue performance are good, and use reliable, the characteristics such as the life-span is long, cheap, its outward appearance is similar to cement products, reclaims without recycle value.Therefore, need not worry robbed or burgled, be the desirable regeneration product eliminated city trap and upgrade other material well comb.
Be described in further detail below in conjunction with accompanying drawing.
