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 bellmouth and the socket, though can reach good impervious requirement, but in today that steel go up day by day, promptly strengthened raw-material cost, made preparation process become very complicated again; And along with the long provided underground of this pipeline; corrosion also can take place in its steel cylinder; the maintenance maintenance cost is higher; and this body external protection mortar quality is more crisp; in lifting, transportation and installation process, be easy to generate microscopic crack; the inner-walls of duct coefficient of friction resistance is big, flow velocity is slow, and pipeline stops up has easily increased maintenance, maintenance cost.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of and have preferably durability, anti-corrosive properties, impermeability, resist uneven settlement, little and raw material of the inner tube wall coefficient of friction resistance and the construction cost cost is low, construction process simple, maintenance maintenance plastic inner lining barrel faucet prestress glass fiber reinforced plastic concrete pipe easily.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of plastic inner lining barrel faucet prestress glass fiber reinforced plastic concrete pipe, constitute by bellmouth, socket, concrete tube core and reinforcement wire, 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, it is characterized in that: the coaxial glass fibre reinforced plastics sheath that is fixed with of this concrete pipe outer core, and at the coaxial plastic inner lining barrel that is fixed with of this concrete pipe in-core wall.
And described socket outer wall directly upwards is shaped on 1-3 groove.
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 on bellmouth and the socket 1≤N≤50 respectively.
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 described reinforcement wire is wrapped on the interior concrete pipe outer core of glass fibre reinforced plastics sheath.
Advantage of the present utility model and beneficial effect are:
1. the coaxial glass fibre reinforced plastics sheath that is fixed with of the tube core outer wall of this plastic inner lining barrel faucet prestress glass fiber reinforced plastic concrete pipe, 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 glass fibre reinforced plastics sheath also has good anti-corrosion, improved the working life of tubing, and the anti-collision ability of glass fibre reinforced plastics sheath is stronger, has avoided the generation of tubing microscopic crack.
2. be wound with reinforcement wire on the tube core outer wall in this plastic inner lining barrel faucet prestress glass fiber reinforced plastic concrete pipe glass fibre reinforced plastics sheath, 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 glass fibre reinforced plastic concrete pipe integral construction cost and difficulty of construction.
3. this plastic inner lining barrel faucet prestress glass fiber reinforced plastic concrete pipe adopts the flexible faucet structure of steel, have good joint Watertightness, 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 socket outer wall of this plastic inner lining barrel faucet prestress glass fiber reinforced plastic concrete pipe directly upwards is shaped on 1-3 groove, by corrosion-resistant O-ring seal is installed the interface between two glass fibre reinforced plastic concrete pipes is sealed in each groove, this cushion rubber is easy for installation, even and when the whole generation of glass fibre reinforced plastic concrete pipe sedimentation, also can guarantee the sealing of whole piece pipeline.
The coaxial plastic inner lining barrel that is fixed with of the inwall of 5 plastic inner lining barrel faucet prestress glass fiber reinforced plastic concrete pipes, this plastic inner lining barrel is that wear-resistant plastic is made, and can reduce the coefficient of friction resistance greatly, improves flow rate of liquid and impermeability, make to be not easy in the pipeline to stop up, reduce the maintenance maintenance cost.
6. the utility model overall structure is simple, design science is reasonable, have preferably durability, anti-corrosive properties, impermeability, resist uneven settlement, little and raw material of the inner tube wall coefficient of friction resistance and construction cost cost are low, construction process is simple, maintenance maintenance is convenient, is the higher plastic inner lining barrel faucet prestress glass fiber reinforced plastic concrete pipe of a kind of novelty.
