Abstract
The invention relates to a steel mouthing socket glass steel concrete pipe which is composed of a mouthing, a socket, and a concrete pipe core; 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 concrete pipe has the advantages of simple structure, scientific and rational 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 glass steel concrete pipe with higher innovation.
Description
Technical field
The present invention relates to concrete plug, especially a kind of 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. occur microscopic crack easily after the tube wall moulding, increased the repairing cost, and influence the aesthetics of whole tubing; 5. body Heavy Weight, transportation and 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; make 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, causes the maintenance maintenance cost higher, and this PCCP outer pipe wall is a cement mortar protective course; after moulding since air-dry and the lifting influence; the protective layer outer wall is easier to occur microscopic crack, 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 deficiencies in the prior art, provide a kind of and have preferably durability, anti-corrosive properties, impermeability, resist that uneven settlement and raw material and construction cost cost are low, construction process simple, maintenance maintenance glass fibre reinforced plastic concrete pipe with steel faucet easily.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of glass fibre reinforced plastic concrete pipe with steel faucet is made of bellmouth, socket, concrete tube core, and bellmouth and socket are packed in the two ends of concrete tube core respectively, it is characterized in that: the coaxial glass fibre reinforced plastics sheath that is fixed with of concrete pipe outer core.
And described socket outer wall directly upwards is shaped on 1-3 groove.
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, 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 this glass fibre reinforced plastics sheath has also strengthened the performance that whole tubing is resisted external pressure earthing and internal water pressure.
2. 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.
3. 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.
4. overall structure of the present invention 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 glass fibre reinforced plastic concrete pipe with steel faucet of a kind of novelty.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is that the A-A of Fig. 1 is to the cross section enlarged view.
Embodiment
The invention will be further described below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
This glass fibre reinforced plastic concrete pipe with steel faucet, constitute by bellmouth 5, socket 1, concrete tube core 3, bellmouth and socket are packed in the two ends of concrete tube core respectively, this socket outer wall directly upwards is shaped on 1-3 groove 2 (the present embodiment accompanying drawing is depicted as 2 grooves), wherein the coaxial glass fibre reinforced plastics sheath 4 that is fixed with of this concrete pipe outer core.The glass fibre reinforced plastics sheath of this 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 invention adopts the preparation process of conventional PCCP tube core, uses the strong concrete one-time cast-forming, and the glass fibre reinforced plastics sheath on this concrete pipe outer core adopts the common process moulding.
Claims (2)
1. a glass fibre reinforced plastic concrete pipe with steel faucet is made of bellmouth, socket, concrete tube core, and bellmouth and socket are packed in the two ends of concrete tube core respectively, it is characterized in that: the coaxial glass fibre reinforced plastics sheath that is fixed with of concrete pipe outer core.
2. glass fibre reinforced plastic concrete pipe with steel faucet according to claim 1 is characterized in that: described socket outer wall directly upwards is shaped on 1-3 groove.
