Technical field
The present invention relates to a kind of pipeline more particularly to a kind of steel fibre high-performance concrete pipe and its manufacturing methods.
Background technique
It is laid on the ordinary reinforced concrete drainage pipeline of underground for a long time, due to interface imprecision, rain, effluent seepage are tight
Weight, influences surface collapse accident caused by basis and gradually increases, and sewage permeation causes the broken of ecological environment into soil
It is bad, have resulted in huge economic loss；Due to ordinary reinforced concrete drainage pipeline thickness of pipe wall, weight weight, tube coupling length is short,
It is difficult to transport and be laid with, it is higher to fundamental importance, therefore overall cost is high；And normal concrete is internal or external in the presence of erosion
When medium, corrosion failure can be generated, structural strength is caused to decline, be unable to reach the requirement of service life, cause resource, the energy
Waste.
Compared to concrete plug, chemical building material tubing (such as FRP sand tube, HDPE pipe) is because having preferable corrosion resistant
Corrosion, lighter weight, and reliable interface pattern, obtain wideling popularize for country, but concrete plug critical external compressive resistance performance
That chemical building material tubing is incomparable, and maintenance cost is low, long service life, still occupied in medium-large caliber drainage pipe compared with
Big market is mainly used for rainfall and sewage pipes road, aqueduct, agricultural irrigation and drainage and pipe-jacking project.At abroad, the market of concrete plug
Occupation rate is higher, and external statistical data is shown, in the drainage pipe greater than DN400, concrete duct accounts for 90%~95%, greatly
Caliber pipe material then 100% uses concrete duct.
Subsoil drain mainly uses ordinary reinforced concrete drainpipe, FRP sand tube and HDPE draining at present
Pipe, since this kind of tubing all has connector imprecision, critical external compressive resistance performance difference is to the demanding disadvantage of installation foundation, service life
It is short, cause the waste of national economy.
Summary of the invention
The present invention provides a kind of steel fibre high-performance concrete pipe and its system to solve the above-mentioned deficiency of the prior art
Make method.
Above-mentioned purpose of the invention is realized by technical solution below: a kind of steel fibre high-performance concrete pipe, packet

It plugs.
The armored concrete tube body includes steel reinforcement cage and high-performance steel fiber concrete layer, high-performance steel fiber concrete
Layer is cast in outside steel reinforcement cage, and the steel bell ring and steel socket ring are respectively welded at steel reinforcement cage both ends.
The high-performance steel fiber concrete layer is raw material by Reactive Powder Concrete, and is stirred in Reactive Powder Concrete
Middle mixing of steel fiber material is mixed, is mixed evenly.
A kind of manufacturing method of steel fibre high-performance concrete pipe, it is characterised in that: the following steps are included:
(1) make tubing main body framework: the high-performance concrete pipe is using a tubulose steel reinforcement cage made of reinforcing bar, in steel
Steel bell ring and steel socket ring is respectively welded in muscle cage both ends；Mono-/bis-annular groove, mono-/bis-ring are had on steel socket ring
O-shaped rubber seal is installed on connected in star；The steel socket ring and steel bell ring of adjacent concrete pipe plug；Steel is held
Framework of steel reinforcement is formed after choma, steel socket ring and steel reinforcement cage welding；
(2) it pours: framework of steel reinforcement will be made and be installed in punching block, be raw material with Reactive Powder Concrete, and in work
Property powder concrete stirring in mixing of steel fiber material formed high-performance steel fiber concrete layer, be poured into assembled mould together
It is formed in tool, the demoulding after concrete hardening.
The Reactive Powder Concrete is a kind of characteristic of high performance concrete change concrete itself, is changed in concrete
Portion's structure improves the resistance to compression and tensile strength of concrete, improves the service life of tubing.Moreover, because mixed using high-performance
Solidifying soil production, increases the resistance to compression and tensile strength of tubing, pipe thickness can be reduced to 10 to the ten/10ths six of bore
/ mono-, mitigate the weight of tubing, pipe length can increase to 5m or more, and reduce connector quantity, improves installation effectiveness,
Reduce the risk of pipeline laying.
Compared with the prior art, the advantages of the invention are the present invention reduces the generation of surface collapse accident, tubing is improved
Service life improves installation effectiveness, cuts operating costs, improve national economic profit.
