The utility model has the advantages that the whole structure is simple, the design is scientific and reasonable, the steel bell and spigot joint prestressed fiberglass reinforced plastic outer sheathing reinforced concrete pipe has better durability, corrosion resistance, impermeability, asymmetric subsidence resistant performance, the raw material and construction cost is low, the construction process is simple, the repair and the maintenance are convenient, and the utility model is the highly innovative steel bell and spigot joint prestressed fiberglass reinforced plastic outer sheathing reinforced concrete pipe.
Description
Technical field
The utility model relates to concrete plug, especially a kind of steel faucet prestress glass fiber reinforced plastic external guard reinforced concrete pipe.
Background technique
Concrete reinforced pipe is to be the industrial products that base material is made through deep processing with cement, have good physics, mechanical property, corrosion-resistant, long service life, characteristics such as maintenance expenses is few, in engineering constructions such as China town and country, industrial and mining enterprise, irrigation and water conservancy and the energy, traffic, communication, obtain using very widely, obtained remarkable social benefit and economic benefit, become indispensable important building material product in the development of the national economy.Concrete reinforced pipe mainly contains spigot and socket type from two kinds of stress concrete reinforced pipe and prestressed reinforced concrete pipes.Concrete reinforced pipe can bear 4-7 kilogram (400～700kPa) working pressure.It can save the great deal of steel and the pig iron with respect to cast iron tube, steel pipe, can not produce corrosion phenomena during water delivery, and long service life can reach about 40 years.Shortcoming is that 1. body impermeabilities are relatively poor; 2. maintenance, maintenance cost is higher; 3. the body Heavy Weight transports and the construction cost height.
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, and the maintenance maintenance cost is higher, and this body external protection mortar quality is more crisp, is easy to generate microscopic crack in lifting, transportation and installation process.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and have preferably durability, anti-corrosive properties, impermeability, resists that uneven settlement and raw material and construction cost cost are low, construction process simple, maintenance maintenance steel faucet prestress glass fiber reinforced plastic external guard reinforced concrete pipe easily.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of steel faucet prestress glass fiber reinforced plastic external guard reinforced concrete pipe, constitute by bellmouth, socket, concrete tube core, reinforcement wire, bellmouth and the coaxial respectively two ends that are packed in the concrete tube core of socket, the outer wall of this concrete tube core twines reinforcement wire, it is characterized in that: the coaxial glass fibre reinforced plastics sheath that is fixed with of this concrete pipe outer core.
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 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 steel faucet prestress glass fiber reinforced plastic external guard reinforced 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 steel faucet prestress glass fiber reinforced plastic external guard reinforced 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 steel faucet prestress glass fiber reinforced plastic external guard reinforced 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 steel faucet prestress glass fiber reinforced plastic external guard reinforced 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.
5. the utility model overall structure is simple, design science is reasonable, have preferably durability, anti-corrosive properties, impermeability, resist uneven settlement, and raw material and construction cost cost are low, construction process is simple, maintenance maintenance is convenient, is the higher steel faucet prestress glass fiber reinforced plastic external guard reinforced concrete pipe of a kind of novelty.
