Description

Nodular cast iron steel fiber well lid

Technical field

The present invention relates to a kind of well lid, is specifically a kind ofly combine by ductile iron integral type well lid skeleton and steel fibrous concrete the well lid prepared.

Background technology

At present, the casting iron well lid that avenue, highway use, Loss is very general, the well lid 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, great demand is there is in people to antitheft, that bearing pressure is large well lid, up to now, also do not find about relevant report of the present invention, the present inventor is through a large amount of development tests, finally successfully develop the anti-stealing manhole cover with being prepared by ductile iron integral type well lid skeleton and steel fibrous concrete, thus complete the present invention.

What object of the present invention was just to provide a kind of ductile iron integral type well lid skeleton and steel fibrous concrete combination preparation has the large well lid of antitheft and supporting capacity.

Another object of the present invention there is provided the preparation method of this well lid.

The solution of the present invention comprises ductile iron integral type well lid skeleton and steel fibrous concrete raw material, steel fibrous concrete raw material is made up of steel fibre, cement, sand and rubble, its design feature first steel fibre, cement, sand, rubble is made steel fibrous concrete, again by steel fibrous concrete and ductile iron integral type well lid skeleton, carry out Combined machining with mould and make.Wherein steel fibre (commercially available) is a kind of steel, filament type material, and it can increase the cohesive force of steel fibre and cement mortar, the bulk strength of Concrete Structure, and its anti-folding, resistance to compression, cracking resistance, scuff resistance are significantly improved.Ductile iron integral type well lid skeleton is the novel product of technical research of adopting new technology, and material is close to steel after nodularization leaching heat treatment for the molten iron of fusing, and inexpensive, have aesthetic in appearance, durable in use, intensity is high, lightweight, uses economic feature.Ductile iron integral type well lid skeleton is set in steel fibre concrete manhole, with steel fibrous concrete, well lid skeleton is wrapped up, skeleton is enclosed in layer of concrete, makes skeleton and air exclusion, never corrosion.Steel fibrous concrete and ductile iron integral type well lid skeleton combine that to solidify rear bonding force very strong, long service life, ductile iron integral type well lid skeleton is wrapped up by steel fibrous concrete, concrete edge in well lid is along being wrapped up by ductile iron integral type well lid skeleton frame, effectively ensure that the bulk strength of well lid, supporting capacity is large, and stability, anti-fatigue performance are good.Well lid can be made to circle, square or rectangular shape by the present invention as required.

The raw material dosage of steel fibrous concrete of the present invention is also that inventor 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 fibre 0.5-3kg cement 10-20kg sand 10-30kg

1, rubble 10-35kg water 2-4kg ductile iron integral type well lid skeleton

Detailed description of the invention

Preparation process of the present invention

1, first by cement 10-20kg, sand 10-30kg, rubble 10-35kg siccative adds mixer and stirs;

2, after being stirred by siccative, then add steel fibre 0.5-3kg, then stir;

3, after stirring, then add water 2-4kg, stir 5-10 minute, obtain steel fibrous concrete material;

4, mould is placed on the vibration platen of bobbing machine upper end, again the ductile iron integral type well lid skeleton cast is put into mould, steel fibrous concrete material is inserted in the mould that ductile iron integral type well lid skeleton is housed, through vibroplatform 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 is strong, and anti-fatigue performance is 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 lid.

Be described in further detail below in conjunction with accompanying drawing.
