With the acceleration of urbanization and the deepening of urban infrastructure construction, pipeline locator has become an indispensable part of urban planning, construction and management. Underground pipelines are an important part of urban infrastructure, including various pipelines and lines for water supply, drainage, gas, electricity, communication, etc., which have a vital impact on the normal operation of the city and the quality of life of the residents. However, due to the hidden nature and complexity of underground pipelines, it is difficult to detect and manage them, so it is of great significance to adopt scientific and effective detection methods and technical means for the safe and stable operation of underground pipelines.
I. Importance of pipeline locator
1. Guarantee the safety and stable operation of urban infrastructure. Underground pipeline is an important part of urban infrastructure, including water supply, drainage, gas, electricity, communications and other pipelines and lines, for the normal operation of the city and the quality of life of the residents has a critical impact. If there is any problem with underground pipelines, it may cause serious safety accidents and quality problems, and bring immeasurable losses to the city's infrastructure. Therefore, pipeline locator is an important means to guarantee the safety and stable operation of urban infrastructure.
2. Improve the efficiency and quality of urban planning and construction. In urban planning and construction, it is necessary to carry out adequate investigation and detection of underground pipelines to understand the distribution, type, material, pipe diameter, burial depth and other factors of underground pipelines for better planning and design. If there is a lack of understanding of underground pipelines, it may lead to unreasonable planning and design, or even safety accidents and quality problems, so pipeline locator can improve the efficiency and quality of urban planning and construction.
3. Promote the sustainable development of the city. The sustainable development of the city needs to be built on the perfect infrastructure, and the underground pipeline is an important part of the urban infrastructure. Through pipeline locator, we can better understand the status quo and demand of urban infrastructure, and provide scientific basis and decision support for the sustainable development of the city.
Second, the method of pipeline locator
According to different types of underground pipelines, the detection methods are different. Generally speaking, the methods of pipeline locator are as follows:
1. direct method. For metal pipelines with large diameter and shallow burial depth, the direct method can be used for detection. The direct method is to place the detection instrument above the pipeline, and receive the signal of the pipeline directly through the instrument, so as to determine the location and burial depth of the pipeline.
2. Clamp method. For the interface for the high resistance body (such as cement interface, rubber ring interface) of the metal pipe, you can use the clamp method for detection. Clamp method is to place the clamp on the pipe interface, through the clamp on the pipe to clamp, so as to realize the positioning of the pipe and the measurement of the depth of burial.
3. Electromagnetic induction method (grounding method). For non-metallic pipelines or occasions where the pipeline cannot be directly contacted, electromagnetic induction method can be used for detection. Electromagnetic induction method is by applying electromagnetic field around the pipeline, so that the pipeline produces induced current, so as to determine the location of the pipeline and the depth of burial through the electromagnetic induction signal strength and frequency and other information.
4. Acoustic wave method. For non-metallic pipelines or the need to trace specific pipelines, the sound wave method can be used for detection. Tracer method is placed inside the pipeline tracer device, through the receiving device on the tracer device issued by the signal to receive, so as to determine the location and direction of the pipeline.
In short, pipeline locator is one of the important links in urban planning and construction, the use of scientific and effective detection methods and technical means is an important means to protect the safety and stable operation of urban infrastructure. In the detection process, different detection methods and technical means should be adopted according to different types of underground pipelines to ensure the accuracy and reliability of the detection results. At the same time, strengthening the maintenance and management of underground pipelines is also one of the important measures to ensure the safe and stable operation of urban infrastructure.
