Abstract
The utility mode relates to a prestressed pipe structure with a wire breaking monitoring function. The prestressed pipe structure comprises a prestressed pipe, and an optical fiber sensor is arranged on the inner wall of the prestressed tube. The prestressed pipe structure is simple, scientific and reasonable in design, convenient to use and low in cost, can effectively monitor the breaking condition of prestressed wires in the tube wall and accurately position broken prestressed wires, and ensures the operating safety of a pipeline.
Description
Technical field
The utility model belongs to the pipeline field, especially a kind of prestressed pipe structure with fracture of wire monitoring function.
Background technique
The prestressed pipe main structure body comprises concrete, reinforcing bar or steel cylinder and reinforcement wire, as long distance, heavy caliber water delivery main force tubing, has wide accommodation, cost performance is high, the life-span is long, anti-seismic performance good, corrosion-resistant, easy for installation, the advantage such as operating cost is low.Just because of these advantages, prestressed pipe is widely used in the fields such as waterpower, water power, municipal water supply, draining by developed countries such as America and Europes.Prestressed pipe application at home starts from late 1980s, and in the last few years, China was built or at the large-scale water delivery engineering of building, and all occupies prostatitis, the world on flow or transmission distance.These engineerings are all used prestressed pipe in a large number.Along with the extensive application of prestressed pipe, to the early warning monitoring of pipeline performance safety, it is more and more important to have seemed.To the statistics of pipe explosion accident, the reinforcement wire fracture is called for short fracture of wire, is the main cause that causes booster according to both at home and abroad.The prestressed pipe that does not also have in the market the fracture of wire monitoring function.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of prestressed pipe structure with fracture of wire monitoring function is provided, this prestressed pipe is simple in structure, design science is reasonable, easy to use, cost is lower, can effectively monitor reinforcement wire crack conditions in the tube wall, accurately the location has ensured the conduit running Security.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of prestressed pipe structure with fracture of wire monitoring function comprises a prestressed pipe, and it arranges optical fiber transducer at the prestressed pipe inwall.
And, embedded light fiber sensor in the described prestressed pipe inwall.
And, installing optical fibres sensor on the described prestressed pipe inwall.
Advantage of the present utility model and beneficial effect are:
Originally the prestressed pipe structure that has the fracture of wire monitoring function comprises a prestressed pipe, it arranges optical fiber transducer at the prestressed pipe inwall, prestressed pipe is simple in structure, design science is reasonable, easy to use, cost is lower, can effectively monitor reinforcement wire crack conditions in the tube wall, accurately the location has ensured the conduit running Security.
Description of drawings
Fig. 1 is structural representation of the present utility model (optical fiber transducer is installed on the prestressed pipe inwall);
Fig. 2 is that the A-A of Fig. 1 is to cutaway view Amplified image;
Fig. 3 is structural representation of the present utility model (omit reinforcement wire, optical fiber transducer is embedded in the prestressed pipe inwall).
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.
A kind of prestressed pipe structure with fracture of wire monitoring function, comprise a prestressed pipe, this prestressed pipe comprises reinforced concrete body 1, be provided with reinforcement wire 3 in this reinforced concrete body, it arranges optical fiber transducer 2 at the prestressed pipe inwall, this optical fiber transducer can be embedded in the prestressed pipe inwall, as shown in Figure 3; Optical fiber transducer can also be installed on the prestressed pipe inwall, as shown in Figure 1.These optical fiber transducer two ends can connect semiconductor laser, Coupler, photodetector, data collecting card and computer realization to the Real-Time Monitoring of reinforcement wire fracture of wire and pipe leakage in the prestressed pipe structure by guiding optical fiber, because optical fiber transducer is placed pipe interior, can be with sensor and the external interference isolation of sensitivity, well solved the problem that is subjected to external interference, so antijamming capability is stronger.In addition, because the reverberation effect in the coupling of water and the pipeline in the pipe, it is very little that the tube wall signal propagates into the decay of sensing optic cable, so monitoring sensitivity is very high.
Claims (3)
1. the prestressed pipe structure with fracture of wire monitoring function comprises a prestressed pipe, it is characterized in that: at the prestressed pipe inwall optical fiber transducer is set.
