The utility model has the advantages of simple overall structure, scientific and reasonable design, excellent durability, non-corrodibility, impermeability and non-uniform sedimentation resistance, low cost for raw material and construction, simple construction technology convenient maintenance and high innovation.
Description
Technical field
The utility model 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 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 is heavier, and 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, 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 pre-stress glass fibre reinforced plastic concrete pipe with steel faucet easily.
The utility model solves its technical problem and is achieved through the following technical solutions:
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, 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 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 glass fibre reinforced plastics sheath that is fixed with of the tube core outer wall of this glass fibre 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.
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 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 pre-stress glass fibre reinforced plastic concrete pipe with steel faucet of a kind of novelty.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to the cross section enlarged view;
Fig. 3 is that the B-B of Fig. 1 is to the cross section enlarged view.
Embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
This pre-stress glass fibre reinforced plastic concrete pipe with steel faucet; by bellmouth 8; socket 1; concrete tube core 3; reinforcement wire 6 and protective layer 7 constitute; bellmouth and socket are packed in the two ends of concrete tube core respectively; 30 longitudinal steel bars 4 of the coaxial uniform setting-in of this concrete pipe in-core; 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 groove 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 can adjust the glass fibre reinforced plastics sheath in tubing working process satisfies engineering is born external pressure load and internal water pressure to tubing needs.
Concrete tube core of the present utility model 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, the pitch of the reinforcement wire that twines at this glass fibre reinforced plastics outer wall is closeer, whole concrete tube core wall thickness is reduced, and have under the situation of same physical property, tubing weight also alleviates to some extent.
