Abstract

The utility model relates to a steel mouthing socket steel wire netting steel pipe non-longitudinal reinforcement prestressed concrete pipe, wherein, axial embedded longitudinal reinforcements are uniformly distributed in a concrete pipe core in same diameter; two ends of the reinforcement are respectively fixed on a mouthing and a socket of the concrete pipe core; the mouthing and the socket are respectively fixed with a steel wire netting pipe and a steel pipe. 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 pipe and steel wire netting are adopted to replace a reinforced skeleton frame, thereby improving the impermeability and the radial stress 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

Steel faucet steel wire net slice steel cylinder non-longitudinal rib prestressed concrete pipe
Technical field
The utility model relates to concrete plug, especially a kind of steel faucet steel wire net slice steel cylinder non-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, 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, has limited the extensive use of concrete pipe.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 non-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 non-longitudinal rib prestressed concrete pipe; constitute by bellmouth, socket, concrete tube core, reinforcement wire, protective layer; 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 concrete pipe outer core cylinder in the protective layer, it is characterized in that: all be fixed with a steel cylinder and a steel fabric sheet on the bellmouth of concrete tube core and socket.
And described steel cylinder is packed in the inner edge position of the bellmouth or the socket of concrete tube core, and steel fabric sheet is packed in the outer rim position of the bellmouth or the socket of concrete tube core.
And described steel cylinder and steel fabric sheet all adopt welding manner to be packed on the bellmouth and socket of concrete tube core.
And described protective layer is a slush.
Advantage of the present utility model and beneficial effect are:
1. only dispose steel cylinder and steel fabric sheet at the concrete pipe in-core and replace Framework Of Steel Reinforcement, 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 has saved the welding process of cylindrical reinforcement frame on process treating, greatly reduces the fabricating cost of tubing, has saved the molding time of whole tubing, has improved the manufacturing efficiency of tubing.
4. the steel cylinder that installs at the two ends of bellmouth or socket can effectively 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 cylinder, steel fabric sheet to replace Framework Of Steel Reinforcement, improved the impermeability and the radial pull 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 non-longitudinal rib prestressed concrete pipe; constitute by bellmouth 1, socket 7, concrete tube core 2, reinforcement wire 5, protective layer 6; 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: be fixed with a steel cylinder 4 and a steel fabric sheet 3 respectively on the bellmouth of concrete tube core and socket, this steel cylinder is packed in the inner edge position of the bellmouth and the socket of concrete tube core, and this steel fabric sheet is packed in the outer rim position of the bellmouth and the socket of concrete tube core.
Steel cylinder and steel fabric sheet all adopt welding manner to be packed on the bellmouth and socket of concrete tube core.
Joint socket of the present utility model is a flexible interface, therefore has good Watertightness, even also can effectively ensure the seal of whole pipeline under the situation of foundation settlement, and prevents that effectively sewage from leaking.Because the utility model adopts steel cylinder, steel fabric sheet to replace Framework Of Steel Reinforcement, has improved the impermeability and the radial stress of concrete pipe; This concrete pipe also is a reinforced concrete construction simultaneously, so can resist sizable external pressure load, thickness of earth-fill cover is little in construction, reduced the difficulty and the construction cost of construction, and maintenance maintenance is simply easy.
