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

Ductile iron steel fibre well is combed

Technical field

The present invention relates to a kind of well and comb, definite a kind of well by ductile iron integral type well comb skeleton and steel fibrous concrete combination preparation that says is combed.

Background technology

At present, the cast iron well that uses on avenue, highway is combed, and Loss is very general, and the well comb insufficient strength of other material is damaged very seriously, brings great potential safety hazard for the vehicle and the pedestrian that go on a journey, and the situation that tumble injury disables happens occasionally.

Summary of the invention

Therefore, people comb to well antitheft, that bearing pressure is large and have great demand, up to now, also do not find about relevant report of the present invention, the inventor is through a large amount of development tests, finally developing by the antitheft well of ductile iron integral type well comb skeleton and steel fibrous concrete preparation of success combed, thereby completed the present invention.

Purpose of the present invention just is to provide a kind of large antitheft well of supporting capacity with ductile iron integral type well comb skeleton and steel fibrous concrete preparation and combs.

Another object of the present invention has been to provide the preparation method that this well is combed.

the solution of the present invention comprises ductile iron integral type well comb skeleton and steel fibrous concrete raw material, the steel fibrous concrete raw material is by steel fibre, cement, sand and rubble form, its design feature is first with steel fibre, cement, sand, rubble is made the steel fibrous concrete material, again steel fibrous concrete material and ductile iron integral type well comb skeleton are made up with mould and be processed into, wherein steel fibre (market is on sale) is a kind of steel, the filament type material, it can increase the cohesive force of steel fibre and cement mortar, strengthen concrete bulk strength, make its anti-folding, resistance to compression, cracking resistance, scuff resistance obviously improves.Ductile iron integral type well comb skeleton is the novel product of technical research of adopting new technology, after the molten iron of fusing soaks heat treatment through nodularization material close to steel, and inexpensive, have aesthetic in appearancely, durable in use, intensity is high, and is lightweight, uses economic characteristics.In the steel fibrous concrete well is combed, ductile iron integral type well comb skeleton is set,, with the well skeleton parcel of combing skeleton is enclosed in layer of concrete with steel fibrous concrete, skeleton and air are completely cut off, never corrosion.It is very strong that rear bonding force is solidified in steel fibrous concrete and the combination of ductile iron integral type well comb skeleton, long service life, ductile iron integral type well comb skeleton is wrapped up by steel fibrous concrete, concrete edge in well is combed is along being wrapped up by ductile iron integral type well comb skeleton frame, effectively guaranteed the bulk strength that well is combed, supporting capacity is large, and stability, anti-fatigue performance is good.The present invention can comb well as required and be made to circle, square or rectangular shape.

The raw material consumption of steel fibrous concrete material of the present invention is also that the inventor draws through a large amount of developments and test repeatedly, and the consumption of each raw material all has effect preferably in the following weight scope.

Steel fibre 0.5-3kg cement 10-20kg sand 10-30kg

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

The specific embodiment

Preparation process of the present invention

1, first with cement 10-20kg, sand 10-30kg, rubble 10-35kg siccative add mixer to stir;

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

3, stir after, then add entry 2-4kg, stirred 5-10 minute, get the steel fibrous concrete material;

4, mould is placed on the vibration platen of bobbing machine upper end, to cast again good ductile iron integral type well comb skeleton and put into mould, the steel fibrous concrete material is inserted in the mould that ductile iron integral type well comb skeleton is housed, through vibroplatform panel vibration 1-3 minute, after moulding, again printing pattern, manually receive light, the demoulding.

The present invention has the characteristics such as bulk strength is high, and supporting capacity is large, and is stable, that anti-fatigue performance is good, uses reliably, and the life-span is long, and is cheap, and its outward appearance is similar to cement products, reclaims without recycle value.Therefore, need not worry robbed or burgledly, be to eliminate the city trap and upgrade the desirable regeneration product that other material well is combed.

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

The specific embodiment

ductile iron integral type well comb skeleton shown in Fig. 1-5 is by frame, horizontal bar and perpendicular muscle form, be provided with successively transversely arranged horizontal bar 4 and vertically disposed perpendicular muscle 6 in frame 1, the height at horizontal bar and perpendicular muscle bottom center place is higher than the height at frame edge place, edge by frame is protruding to downward-extension, be convex mutually arranged in a crossed manner in frame, be cast as one with frame, the inboard, the end of frame is provided with load-bearing supporting plate 5, the two ends up and down of ductile iron integral type well comb skeleton are filled with steel fibrous concrete, steel fibrous concrete and the combination of ductile iron integral type well comb skeleton are solidified as one, the upper surface that well is combed is provided with the upper plane 2 of well comb of steel fibrous concrete preparation, the lower surface that well is combed be provided with the steel fibrous concrete preparation at the bottom of the convex of lower convexity 7, at the bottom of the steel fibrous concrete convex with the horizontal bar 4 of ductile iron integral type well comb skeleton, perpendicular muscle 6 correspondence that matches, be wrapped in the ductile iron integral type well comb skeleton outer bottom of muscle anyhow, the middle part that well is combed is provided with transversely arranged spilled water hole 3 successively.Described spilled water hole also can be equipped with together with ductile iron integral type well comb skeleton vertical array as required.Four sides of described ductile iron integral type well comb skeleton horizontal bar and perpendicular muscle are provided with the outwardly anticreep tooth 8 that increases bonding force that has.
