The utility model has the advantages of very simple integral structure, scientific and reasonable design, good durability, impermeability and water seal capability of joint. The steel wire netting, the steel pipe and the longitudinal reinforcement are adopted to replace a reinforced skeleton frame, thereby effectively improving the radial tension of the concrete pipe, overcoming the occurrence of cracks, and prolonging the service life of the concrete pipe. The utility model is of few using amount of steels, simple repair and maintenance and convenient construction operation, thereby greatly reducing the product cost and construction cost, and providing conditions for wide using of concrete pipes.
Description
Technical field
The utility model relates to concrete plug, especially a kind of steel faucet steel wire net slice steel cylinder longitudinal rib prestressed concrete pipe.
Background technique
The steel faucet prestressed concrete pipe is a kind of pipeline that is mainly used in municipal administration, water conservancy, electric power, urban water supply system, also often is used in industrial waterline, field irrigation, plant pipe network.Present steel faucet prestressed concrete pipe cost is higher,, cause the high main cause of steel faucet prestressed concrete plumber journey cost to be: 1. the rise of price of steel product causes that cost increases.The concrete pipe in-core is embedded with cylindrical reinforcement frame, and this Framework Of Steel Reinforcement is by a plurality of vertical muscle and circumferential reinforcement colligation or be welded, and the use amount of steel is bigger; 2. the Framework Of Steel Reinforcement fabricating cost is higher.When adopting artificial assembling reinforcement skeleton, manufacturing efficiency is lower, and the manufacture cycle is longer, and defect rate is higher; When adopting special device to install Framework Of Steel Reinforcement with welding manner, though the manufacture cycle shortens, defect rate reduces, and the machinery cost is higher.
In the actual production of steel faucet prestressed concrete pipe, the female end of inner tube wall and socket end are prone to microscopic crack, and the not high enough generation that also can cause microscopic crack of tube core longitudinal pulling force at present.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, reasonable in design, with low cost, less steel faucet steel wire net slice steel cylinder longitudinal rib prestressed concrete pipe of use reinforcing bar is provided.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of steel faucet steel wire net slice steel cylinder longitudinal rib prestressed concrete pipe; by bellmouth; socket; the concrete tube core; reinforcement wire; protective layer constitutes; bellmouth is coaxial and be packed in the two ends of concrete tube core respectively with socket; protective layer is coaxial on concrete pipe outer core cylinder; reinforcement wire is wrapped on the interior concrete pipe outer core cylinder of protective layer; it is characterized in that: indulge muscle with the uniform axial setting-in in footpath at the concrete pipe in-core; the two ends that should indulge muscle are packed on the bellmouth and socket of concrete tube core respectively, all are fixed with a steel fabric sheet tube and a steel cylinder at bellmouth and socket position.
And, be N at the concrete pipe in-core vertical muscle of the uniform axial setting-in in footpath together, 1≤N≤50.
And described steel cylinder is packed in the inner edge at bellmouth and socket position, and steel fabric sheet is packed in the outer rim of vertical muscle.
And described vertical muscle adopts welding manner to be packed on the bellmouth and socket of concrete tube core, and described steel fabric sheet tube and steel cylinder all adopt welding manner to install.
And described protective layer is a slush.
Advantage of the present utility model and beneficial effect are:
1. substitute Framework Of Steel Reinforcement at the vertical muscle of concrete pipe in-core configuration, steel cylinder and steel fabric sheet, its concrete pipe outer core keeps original reinforcement wire, whole tube core still is a reinforced concrete construction, makes tubing still have very strong resistance to pressure like this, but the steel material that uses reduces greatly.
2. adopt flexible faucet structure, have good joint Watertightness, and constructing operation is easy, tube material and tube wall is thin, and the body own wt is lighter, and the opposing uneven settlement is very capable.
3. this concrete pipe in-core portion adopts the structural type of steel fabric sheet, steel cylinder and vertical muscle, not only improved the radial pull of concrete pipe, overcome the generation of crackle, on process treating, saved simultaneously the welding process of cylindrical reinforcement frame, greatly reduce the fabricating cost of tubing, save the molding time of whole tubing, improved the manufacturing efficiency of tubing.
4. the steel cylinder that installs of bellmouth or socket end can improve the impermeability of bellmouth or socket end.
5. the utility model overall structure is very simple, design science is reasonable, have favorable durability, impermeability and joint water closure, adopt steel fabric sheet, steel cylinder and vertical muscle to replace Framework Of Steel Reinforcement, improved the radial stress of concrete pipe effectively, overcome the generation of crackle, prolonged the working life of concrete pipe, the steel use amount is less, and maintenance maintenance is simple and constructing operation is easy, greatly reduce the cost and the construction cost of product, be the widely-used condition of having created of concrete pipe.

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 steel faucet steel wire net slice steel cylinder longitudinal rib prestressed concrete pipe; constitute by bellmouth 1, socket 8, concrete tube core 2, reinforcement wire 5, protective layer 7; bellmouth is coaxial and be packed in the two ends of concrete tube core respectively with socket; protective layer is a slush and coaxial on concrete pipe outer core cylinder, and reinforcement wire is wrapped on the interior concrete pipe outer core cylinder of protective layer.Innovative point of the present utility model is: indulge muscle 6 at the concrete pipe in-core with uniform axially being embedded with in footpath, vertical muscle is N, 1≤N≤50; The two ends that should indulge muscle are packed on the bellmouth and socket of concrete tube core respectively, on the vertical muscle at bellmouth and socket position, be fixed with a steel fabric sheet tube 3, this steel fabric sheet tube is packed in the outer rim position of indulging muscle by welding manner, all is fixed with a steel cylinder 4 at bellmouth and socket position.
Steel cylinder is packed in the inner edge at bellmouth and socket position in the present embodiment, and steel fabric sheet is packed in the outer rim of vertical muscle.
Vertical muscle adopts welding manner to be packed on the bellmouth and socket of concrete tube core, and steel fabric sheet tube and steel cylinder all adopt welding manner to install.
Innovative point of the present utility model is: indulge muscle 5, (as required, also can be packed in its inner rim position) at the concrete pipe in-core with the uniform axial setting-in in footpath.
