Abstract
The invention relates to a steel mouthing socket prestressing force glass steel concrete pipe which is composed of a mouthing, a socket, a concrete pipe core, a prestressing force steel wire and a protection layer; the mouthing and the socket are fixedly arranged at two ends of the concrete pipe core respectively, wherein, the outer wall of the concrete pipe core is coaxially and fixedly provided with a fiberglass sheath, the outer wall of which is wrapped with the prestressing force steel wire and fixedly provided with the protection layer. The concrete pipe has the advantages of simple structure, scientific and reasonable design, good durability, corrosion resistance, impermeability, uneven sedimentation resistance, low raw material cost and low construction cost, simple construction process and easy maintenance, and is a steel mouthing socket prestressing force glass steel concrete pipe with higher innovation.
Description
Technical field
The present invention relates to concrete plug, especially a kind of pre-stress glass fibre reinforced plastic concrete pipe with steel faucet.
Background technique
In the present employed all kinds of concrete water transmission pipes of China; Mainly contain the concrete drain tile of self-stressing concretes pipe, prestressed concrete pipe and other various interface forms according to classification, be mainly used in municipal administration, water conservancy, road and bridge, urban water supply system, industrial waterline, field irrigation, plant pipe network and dark earthing culvert pipe etc.Though these tubing can reach the purpose of water delivery to a certain extent, exist some technological deficiencies: 1. impervious relatively poor; 2. anti-corrosive properties are relatively poor; 3. maintenance, maintenance cost is higher; 4. the body Heavy Weight transports and the construction cost height.
Find a kind of PCCP tubing through retrieval; This tubing is on available coagulation soil tubing basis, and coaxial setting-in approaches steel cylinder in its tube core, and the two ends of this thin 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 is heavier, and transportation and construction cost are higher.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing technology, provide a kind of and have preferably durability, anti-corrosive properties, impermeability, resist that uneven settlement property and raw material and construction cost cost are low, construction process simple, maintenance maintenance pre-stress glass fibre reinforced plastic concrete pipe with steel faucet easily.
The present invention solves its technical problem and realizes through following technological scheme:
A kind of pre-stress glass fibre reinforced plastic concrete pipe with steel faucet; 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; It is characterized in that: the coaxial glass fibre reinforced plastics sheath that is fixed with of concrete pipe outer core, this glass fibre reinforced plastics sheath outer wall is wound with reinforcement wire, is fixed with protective layer at this glass fibre reinforced plastics sheath outer wall.
And described concrete pipe in-core is coaxial to be uniformly distributed with setting-in N root longitudinal steel bar, and the two ends of this longitudinal steel bar are packed on bellmouth and the socket 1≤N≤50 respectively.
And described socket outer wall directly upwards is shaped on 1-3 grooves.
And described protective layer is a slush.
Advantage of the present invention and beneficial effect are:
1. the coaxial glass fibre reinforced plastics sheath that is fixed with of the tube core outer wall of this glass fibre reinforced plastic concrete pipe makes whole body have good impermeability, compares 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; Practiced thrift 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.
2. the tube core outer wall of this glass fibre reinforced plastic concrete pipe 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 glass fibre reinforced plastic concrete pipe integral construction cost and difficulty of construction.
3. this glass fibre 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 glass fibre reinforced plastic concrete pipe directly upwards is shaped on 1-3 grooves; Through 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. overall structure of the present invention is simple, design science is reasonable; Have preferably durability, anti-corrosive properties, impermeability, resist uneven settlement property; And raw material and construction cost cost are low; Construction process is simple, and maintenance maintenance is convenient, is the higher pre-stress glass fibre reinforced plastic concrete pipe with steel faucet of a kind of novelty.

Embodiment
Through specific embodiment the present invention is made further detailed description below, following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
This pre-stress glass fibre reinforced plastic concrete pipe with steel faucet; Constitute by bellmouth 8, socket 1, concrete tube core 3, reinforcement wire 6 and protective layer 7; Bellmouth and socket are packed in the two ends of concrete tube core respectively, and this concrete pipe in-core is coaxial to be uniformly distributed with 30 longitudinal steel bars 4 of setting-in, and the two ends of this longitudinal steel bar are packed in respectively on bellmouth and the socket; This socket outer wall directly upwards can be shaped on 1-3 grooves 2 (the present embodiment accompanying drawing is depicted as 2 grooves); The coaxial glass fibre reinforced plastics sheath 5 that is fixed with of this concrete pipe outer core wherein, this glass fibre reinforced plastics sheath outer wall twines reinforcement wire, and is fixed with the protective layer of slush at this glass fibre reinforced plastics sheath outer wall.
The glass fibre reinforced plastics sheath of this pre-stress glass fibre reinforced plastic concrete pipe with steel faucet can adopt the epoxy resin of different performance according to the needs of stratum water quality; Reaching anticorrosion impervious characteristics, and the number of plies that in tubing working process, can adjust the glass fibre reinforced plastics sheath satisfies engineering is born external pressure load and internal water pressure to tubing needs.
Concrete tube core of the present invention adopts the preparation process of conventional PCCP tube core; Use the strong concrete one-time cast-forming; Glass fibre reinforced plastics sheath on this concrete pipe outer core adopts the common process moulding, and the pitch of the reinforcement wire that twines at this glass fibre reinforced plastics outer wall is closeer, and whole concrete tube core wall thickness is reduced; And have under the situation of same physical property, tubing weight also alleviates to some extent.
