The underground pipeline locator is an important tool for detecting and locating underground pipelines and cables. The following is a detailed introduction to the underground pipeline locator:
1. Definition and Classification
Underground pipeline locator, also known as pipeline detector, is a device that uses theories such as electromagnetic signals and inertial navigation to detect the position and depth of underground metal pipelines, cables, and other types of pipelines (such as non-metallic pipelines). According to different detection principles and technical methods, underground pipeline locators can be divided into various types, among which common ones include pipeline locators and underground pipeline inertial locators (pipeline inertial gyroscopes).
2. Working principle
① Pipeline locator:
Mainly based on electromagnetic signal theory for work.
Composed of a receiver and a transmitter, the transmitter sends electromagnetic signals to the underground pipeline, and the receiver receives and analyzes these signals to determine the location and depth of the pipeline.
② Inertial positioning device for underground pipelines:
Adopting inertial navigation technology, utilizing integrated navigation and multi-sensor information fusion and error online compensation technology based on IMU (Inertial Measurement Unit)/mileage/motion characteristics/environmental characteristics.
By using instruments or robots equipped with inertial navigation modules to move inside the pipeline and measure their motion trajectories, three-dimensional information of underground pipelines can be obtained.
3. Functional Features
① Pipeline locator:
It has design features such as lightweight, low power consumption, and waterproof.
Capable of quickly and accurately completing the tasks of planar positioning and depth measurement of underground facilities.
Provide multiple user settings options, such as selectable frequency, language, feature settings, etc.
It has advanced functions such as peak arrow, true depth, passive avoidance, and dynamic overload protection.
② Inertial positioning device for underground pipelines:
Can accurately and reliably obtain three-dimensional information of underground pipelines in complex urban environments.
Not affected by factors such as the depth of underground pipelines, detection distance, material, geological environment, and external magnetic fields.
It has centimeter level accuracy and is suitable for measuring pipelines of various diameters.
4. Application scenarios
① Pipeline locator:
Mainly used for identifying and locating underground facilities before safe excavation.
Suitable for scenarios such as general survey, pre construction detailed investigation, and emergency repair of pipelines for electricity, gas, oil, heat, communication, etc.
② Inertial positioning device for underground pipelines:
In addition to being suitable for the above scenarios, it is also particularly suitable for accurate detection of existing pipelines and accurate measurement of completed pipelines.
At archaeological excavation sites, it can also be used to distinguish between natural strata and artificially disturbed pipeline areas.
5. Operation and precautions
① Operation:
When using a pipeline locator, it is necessary to choose the appropriate transmitter frequency and receiver settings.
When using an underground pipeline inertial positioning instrument, it is necessary to follow the prescribed measurement steps, including preparation of the measurement environment, instrument inspection and setting, data measurement and recording, etc.
② Attention:
When using any type of underground pipeline locator, it is necessary to ensure that the instrument is in good working condition.
During the measurement process, it is necessary to follow relevant safety operating procedures to avoid damage to underground facilities or personal injury.
Measurement data needs to be analyzed and processed reasonably to ensure the accuracy and reliability of the results.
In summary, underground pipeline locator is an indispensable and important tool in urban construction and maintenance. By selecting and using different types of locators reasonably, accurate detection and positioning of underground pipelines can be achieved, providing strong support for urban planning and construction.
