Description
Technical field
The utility model relates to concrete plug, especially a kind of prestressed reinforced concrete pipe with plastic inner lining barrel spigot.
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 purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of prestressed reinforced concrete pipe with plastic inner lining barrel spigot is provided; 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 utility model solves its technical problem and is achieved through the following technical solutions:
A kind of prestressed reinforced concrete pipe with plastic inner lining barrel spigot; constitute by bellmouth, socket, concrete tube core, reinforcement wire and protective layer; bellmouth and the coaxial respectively two ends that are packed in the concrete tube core of socket; reinforcement wire is wrapped on the outer wall of concrete tube core; be fixed with protective layer at this tube core outer wall, it is characterized in that: the coaxial plastic inner lining barrel that is fixed with of this concrete pipe in-core wall.
And described plastic inner lining barrel is made by wear-resistant plastic and this plastic inner lining barrel radially installs a plastics shutoff in that the end face of spigot is coaxial; Plastic inner lining barrel radially installs a plastics shutoff in that socket is also coaxial, and these two plastics shutoff and plastic inner lining barrel and bellmouth, the equal vertical hot melting of socket install.
And, the coaxial uniform setting-in N root longitudinal steel bar of described concrete pipe in-core, and 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 utility model and beneficial effect are:
1. the coaxial plastic inner lining barrel that is fixed with of the tube core inwall of this prestressed reinforced concrete pipe with plastic inner lining barrel spigot, plastic inner lining barrel are in spigot and socket end face, and the radially vertical coaxial plastics shutoff that is fixed with; Plastic inner lining barrel encapsulates the concrete tube core at socket by another plastics shutoff.Plastic inner lining barrel, plastics shutoff, plastics bellmouth and socket have been formed 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 inner lining barrel also has good anti-corrosion, improved the working life of tubing.
2. this prestressed reinforced concrete pipe with plastic inner lining barrel spigot outer wall 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 plastic inner lining barrel spigot integral construction cost and difficulty of construction.
3. this prestressed reinforced concrete pipe with plastic inner lining barrel spigot 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 plastic inner lining barrel spigot directly upwards is shaped on 1-3 groove, by corrosion-resistant O-ring seal is installed the interface between two prestressed reinforced concrete pipe with plastic inner lining barrel spigot 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. the utility model overall structure is simple, design science is reasonable, adopt plastic inner lining barrel as liner can realize concrete pipe 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 plastic inner lining barrel spigot of a kind of novelty.
