Abstract
The invention relates to a bell-spigot prestressed concrete reinforced pipe with a tube core externally lined with a plastic sleeve, which is composed of a bell mouth, a spigot mouth, a concrete pipe core, an prestressed steel wire and a protective layer, the bell mouth and the spigot mouth are respectively mounted at two ends of the concrete pipe core fixedly, wherein a plastic sleeve is coaxially mounted on the outer wall of the concrete pipe core fixedly, the protective layer is coaxially mounted on the outer wall of the plastic sleeve fixedly, and the prestressed steel wire is wound coaxially around the outer wall of the plastic sleeve in the protective layer. The prestressed concrete reinforced pipe is simple in integral structure, scientific and reasonable in design, and relatively fine in impermeability and noncorrosibility, resists uneven settleability, and further is low in raw materials cost and construction cost, simple in construction technique and convenient in maintenance and repair, and relatively high in creativity.
Description
Technical field
The present invention relates to concrete plug, especially a kind of prestressed reinforced concrete pipe with tube core externally lining with plastic sleeve faucet.
Background technique
Along with the increasing of China to the infrastructure dynamics, the demand of tubing also is increasing, especially long distance water transfer tubing.At present in China's Long-distance Water Transmission Pipeline, concrete plug occupies larger specific gravity, and the tube core of concrete plug mostly is the reinforced concrete moulding by casting, though have the good performance of resisting external pressure load and internal water pressure, but its body is impervious relatively poor in growing apart from course of conveying, and the joint socket of its concrete material for the ability of resisting foundation settlement a little less than, find a kind of PCCP tubing by retrieval, this tubing is on available coagulation soil tubing basis, the thin steel cylinder of coaxial setting-in in its tube core, and the two ends that should approach steel cylinder are welded on the bellmouth and socket of steel, can reach good impervious requirement, but in today that steel go up day by day, promptly strengthened raw-material cost, make preparation process become very complicated again, and the bellmouth of this pipeline and socket are steel, before piping laying, need it is done preservative treatment, the cost of labor and the cost of raw material have been increased greatly, and along with the long provided underground of this pipeline, corrosion also can take place in its steel cylinder, cause the maintenance maintenance cost higher, and this body is heavier, transportation and construction cost are higher.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of prestressed reinforced concrete pipe with tube core externally lining with plastic sleeve faucet is provided, and this pipe has preferably impermeability, anti-corrosive properties, resist uneven settlement and raw material and the construction cost cost is low, construction process is simple, maintenance maintenance is convenient.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of prestressed reinforced concrete pipe with tube core externally lining with plastic sleeve faucet; constitute by bellmouth, socket, concrete tube core, reinforcement wire and protective layer; bellmouth and socket are packed in the two ends of concrete tube core respectively; it is characterized in that: the coaxial plastic sleeve that is fixed with of concrete pipe outer core, coaxial protective layer and the coaxial reinforcement wire that is wound with of the plastic sleeve outer wall in this protective layer of being fixed with of this plastic sleeve outer wall.
And plastic sleeve and socket outer wall are diametrically by plastics shutoff encapsulation, and plastic sleeve and bellmouth inwall are diametrically by another plastics shutoff encapsulation.
And, the coaxial uniform setting-in N root longitudinal steel bar of described concrete pipe in-core, the two ends of this longitudinal steel bar are packed in respectively on bellmouth and the socket, and 1≤N≤50.
And, the coaxial cylindrical reinforcement frame that is fixed with of described concrete pipe in-core, the two ends of this cylindrical reinforcement frame are packed in respectively on bellmouth and the socket, and this cylindrical reinforcement frame is made of longitudinal steel bar and circumferential reinforcement.
And described socket outer wall directly upwards is shaped on 1-3 groove.
And described protective layer is a slush.
Advantage of the present invention and beneficial effect are:
1. the coaxial plastic sleeve that is fixed with of the tube core outer wall of this prestressed reinforced concrete pipe with tube core externally lining with plastic sleeve faucet, and plastic sleeve and socket outer wall are diametrically by plastics shutoff encapsulation, plastic sleeve and bellmouth inwall are diametrically by another plastics shutoff encapsulation, like this, plastic sleeve, the plastics shutoff, plastics bellmouth and socket constitute an airtight body, make whole body have good impermeability, compare with existing P CCP tubing, have under the equal good impermeability at body, saved the steel cylinder in the tube core, in iron and steel price growing today, saved the cost of raw material greatly, improved economic benefit, and this plastic sleeve also has good anti-corrosion, improved the working life of tubing.
2. the plastic sleeve outer wall of this prestressed reinforced concrete pipe with tube core externally lining with plastic sleeve faucet is wound with reinforcement wire, strengthen whole tubing greatly and resisted the ability of external pressure earthing and internal water pressure, under equal external pressure earthing and internal water pressure situation, make the wall thickness attenuation of overall die, alleviate the weight of whole tubing, reduce prestressed reinforced concrete pipe with tube core externally lining with plastic sleeve faucet integral construction cost and difficulty of construction.
3. this prestressed reinforced concrete pipe with tube core externally lining with plastic sleeve faucet adopts the flexible faucet structure that plastics are made, compare with socket with PCCP steel bellmouth, the cost of raw material is lower, even do not do preservative treatment, also has good antiseptic effect, but also have joint Watertightness preferably, and constructing operation is easy; Because this tube material and tube wall is thinner, the body own wt is lighter, has also improved the ability of opposing uneven settlement to a certain extent.
4. the plastics socket outer wall of this prestressed reinforced concrete pipe with tube core externally lining with plastic sleeve faucet directly upwards is shaped on 1-3 groove, by corrosion-resistant O-ring seal is installed the interface between two plastic lining sleeve faucet prestress reinforced concrete pipes is sealed in each groove, this cushion rubber is easy for installation, even and when the whole generation of this pipe sedimentation, also can guarantee the sealing of whole piece pipeline.
5. overall structure of the present invention is simple, design science is reasonable, have preferably impermeability, anti-corrosive properties, resist uneven settlement, and raw material and construction cost cost are low, construction process is simple, maintenance maintenance is convenient, is the higher prestressed reinforced concrete pipe with tube core externally lining with plastic sleeve faucet of a kind of novelty.
