Abstract

The utility model relates to a steel mouthing socket non-longitudinal reinforcement prestressed concrete pipe which consists of a mouthing, a socket, a concrete core, a prestressed steel wire and a protective layer, wherein, the mouthing and the socket are respectively fixed at two ends of the concrete pipe core; the protective layer is coaxially arranged on a cylinder surface of the outer wall of the concrete pipe core; the prestressed steel wire is winded on the cylinder surface of the outer wall of the concrete pipe core in the protective layer. 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 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 non-longitudinal rib prestressed concrete pipe

Technical field

The utility model relates to concrete plug, especially a kind of steel faucet 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, 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, causes 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.

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, steel faucet non-longitudinal rib prestressed concrete pipe of not using vertical muscle is provided.

The utility model solves its technical problem and is achieved through the following technical solutions:

A kind of steel faucet non-longitudinal rib prestressed concrete pipe; constitute by bellmouth, socket, concrete tube core, reinforcement wire, protective layer; it is characterized in that: bellmouth and the coaxial respectively two ends that are packed in the concrete tube core of socket; protective layer is coaxial on concrete pipe outer core cylinder, and reinforcement wire is wrapped on the interior concrete pipe outer core cylinder of protective layer.

And described protective layer is a slush.

Advantage of the present utility model and beneficial effect are:

1. at concrete pipe in-core cancellation Framework Of Steel Reinforcement, its concrete pipe outer core keeps original reinforcement wire, 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 form only have or not vertical muscle, has saved the welding process of cylindrical reinforcement frame on process treating, greatly reduces the fabricating cost of tubing, and the molding time of having saved whole tubing has improved the manufacturing efficiency of tubing.

4. the utility model overall structure is very simple, design science is reasonable, have favorable durability, impermeability and joint water closure, the steel use amount is less, 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.

Description of drawings

Fig. 1 is the utility model structural representation (broken section);

Fig. 2 is that the A-A of Fig. 1 is to cross-sectional view;

Fig. 3 is that the B-B of Fig. 1 is to cross-sectional 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 steel faucet non-longitudinal rib prestressed concrete pipe is made of bellmouth 1, socket 5, concrete tube core 2, reinforcement wire 3, protective layer 4, and protective layer is a slush.Wherein bellmouth is that metal is made and the coaxial respectively two ends that are packed in the concrete tube core with socket, and protective layer is coaxial on concrete pipe outer core cylinder, and reinforcement wire is wrapped on the interior concrete pipe outer core cylinder of protective layer.

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 fed sheet of a media from leaking.Because the utility model does not have Framework Of Steel Reinforcement, but can resist sizable external pressure load, thereby reduce the difficulty and the construction cost of construction, and maintenance maintenance is simply easy by improving concrete strength.

Claims

1. steel faucet non-longitudinal rib prestressed concrete pipe; constitute by bellmouth, socket, concrete tube core, reinforcement wire, protective layer; it is characterized in that: bellmouth and the coaxial respectively two ends that are packed in the concrete tube core of socket; protective layer is coaxial on concrete pipe outer core cylinder, and reinforcement wire is wrapped on the interior concrete pipe outer core cylinder of protective layer.

2. steel faucet non-longitudinal rib prestressed concrete pipe according to claim 1 is characterized in that: described protective layer is a slush.
