Description
Technical field
This utility model belongs to equipment for liquid transportation technical field, is specifically related to a kind of Prestressed concrete cylinder pipe.
Background technology
At present, Prestressed concrete cylinder pipe (is called for short PCCP), is a kind of novel rigid pressure tubing.It is with steel
The strong concrete tube core of cylinder is wound around compressor wire, sprays with cement mortar protective course, use steel bell and spigot steel loop and with
Steel cylinder is welded into one, and the fluted O-ring seal of bell and spigot band defines the flexible joint of slidingtype cushion rubber, be steel plate, concrete,
High tensile steel wire and the composite construction of cement mortar different materials composition, have steel and the respective characteristic of concrete.Prestress steel
Cylinder pipe of concrete has and bears that interior external pressure is high, joint tighness is good, shock resistance is strong, it is convenient and swift to execute, antiseptic property good, ties up
Protect the characteristics such as convenient, paid close attention to by engineering circles, be mainly used in long distance water transfer main line, pressure inverted-siphon, urban water supply engineering,
Pressure water conveyer pipeline, electric power plant circulating water engineering pipeline, pressure blowdown main etc..Compared with conventional tubing, have applied widely,
The advantages such as economic life length, anti-seismic performance are good, easy for installation, it is low to run expenditure, the most water-tight.Prestressed concrete cylinder pipe
Two kinds can be divided into: a kind of is lined Prestressed concrete cylinder pipe (PCCPL), i.e. in steel cylinder inwall molding from structural shape
Concrete, is directly wound around ring orientation prestress steel wire outside steel cylinder, then gunite protective layer and the pipeline made；One
Planting is embed-type Prestressed concrete cylinder pipe (PCCPE), is to be embedded in by steel cylinder inside tube core concrete, then mixes at tube core
It is wound around gunite protective layer after ring orientation prestress steel wire on solidifying soil outer wall.
In recent years, joint sealing performance was good, rigidity owing to having for embed-type Prestressed concrete cylinder pipe (PCCPE)
Greatly, decay resistance is strong and the feature such as structural safety, obtains emphasis application at home in emphasis diversion works.But it is embed-type pre-
Stress cylinder concrete pipe (PCCPE) twines silk etc. owing to producing with the handling in transportation, the drying shrinkage of tube core concrete, pipe
Reason, causes inwall local to produce tension, hoop crack easily occurs in especially near socket end 300mm of its inwall, although
Take crack in these and sometimes can not keep away rabbit, also the safe handling of pipeline will not be produced big impact, but often make life
Produce enterprise and feel more worried, because their client is mostly reluctant to fall the fact that there is crack, because of inwall crack by by its product
Embed-type Prestressed concrete cylinder pipe (PCCPE) the quality dispute produced is of common occurrence in practical engineering application.
Utility model content
For above-mentioned weak point of the prior art, the purpose of this utility model is intended to provide one enough effectively prolongations
In the service life of Prestressed concrete cylinder pipe, it is adaptable to the occasion that operating pressure is higher, eliminate Prestressed concrete cylinder pipe
The Prestressed concrete cylinder pipe in inner surface crack.
In order to solve above-mentioned technical problem, this utility model is achieved through the following technical solutions: a kind of prestress steel
Cylinder pipe of concrete, it includes concrete tube core and is wrapped in the stress wire of concrete tube core outer rim, the one of concrete tube core
End is socket end, and the other end of concrete tube core is female end, and described pipe of concrete in-core wall is provided with steel cylinder, in described steel cylinder
Wall is provided with interior layer concrete, and described socket end is provided with socket steel ring, and described female end is provided with bellmouth steel loop, described stress
Steel wire outer rim is provided with protective layer；Described pipe of concrete core inner is additionally provided with steel skeleton, socket steel ring and bellmouth steel loop and all welds
Being connected on steel cylinder, the outer rim end of described protective layer is provided with reinforcement.
Preferably, described socket steel ring being provided with mounting groove and pressure testing hole, described pressure testing hole is arranged at adjacent two
Between described mounting groove, described mounting groove and pressure testing hole may be contained within the working end of socket steel ring.
Preferably, the outer rim of described stress wire contacts with each other.
Preferably, described concrete tube core being additionally provided with stress wire anchoring piece, described stress wire anchoring piece is pre-
It is embedded in the outer rim of concrete tube core end.
Being disposed to of steel skeleton avoids the inner surface of Prestressed concrete cylinder pipe hoop crack, i.e. steel skeleton occur
Be disposed to strengthen pipe of concrete in-core wall concrete in tension district stress intensity, steel skeleton is axially set in pipe of concrete
Core inner, the Main Function of steel skeleton is to bear axial top power together with concrete tube core, protect stress wire, bear external load
Effect, steel skeleton can replace with steel fibre.
Stress wire anchoring piece is used for fixing stress wire；Pressure testing hole is used for checking whether mounted pipe joint seals
Well；Protective layer is cement mortar protective course or concrete cover；Reinforcement is in order to improve tubing anti-axial thrust ability.
Stress wire makes concrete tube core produce compressive pre-stress, enables pipeline to bear internal water pressure and external load, stress
The outer rim of steel wire contacts with each other, it is ensured that pipeline can bear internal water pressure and external applied load to greatest extent, improves the work of pipeline
Make pressure and service life.
Nominal bore diameter of the present utility model is 800mm, and operating pressure is 3.0Mpa.
This utility model design science is reasonable, has good durability, impermeability, cracking resistance, corrosion resistance, and makes
Making technique simple, arrange interior layer concrete through steel cylinder inwall, the embed-type Prestressed concrete cylinder pipe life-span is effectively prolonged
Long, can effectively eliminate the crack of pipe of concrete in-core wall through arranging steel skeleton at pipe of concrete core inner, be a kind of innovation
The embed-type Prestressed concrete cylinder pipe that property is higher.
