Many times, the staff will perform the instrument's detection and test before use in order to ensure the normal use of the instrument or the equipment. Different equipment, the direction in which you need to detect is different. Xiaobian is going to introduce you today that the underground pipeline detector is used, and the staff will perform the instrument's detection and trial before use in order to ensure the normal use of the equipment.
Different equipment, the direction in which you need to detect is different. Xiaobian wants to introduce you to the verification process before using the underground pipeline detector, I hope everyone can gain something. In order to ensure the effectiveness and accuracy of the underground line detection results, all underground pipeline detection devices that are put into use should be verified.
The instrument checks include the stability checks of single instruments and the consistency check of similar multiple instruments. Instrument consistency checks include flat positioning consistency checks and dense consistency checks for similarly to Underground Pipeline detection equipment. It is advisable to perform in a single, known underground line or pipeline laying conditions relatively simple.
The stability checking of a single underground pipeline detector uses the same working parameters to the same position, and the underground pipeline in the same interference environment is not less than 2 repetitive detection, positioning and depth results of different times. The maximum difference should not be greater than the limit of the relevant procedures. The detection result should reflect repetitiveness of the method in time. Consistency checking of multiple underground line detectors: Under the premise of satisfying a single consistency, counting multiple instruments' positioning accuracy and ingredients of depth precision meet the requirements of relevant procedures.
Multiple instrument consistency checks and method tests should be carried out at the same time, select the same detection parameters, carry out the same location and the same interference environmental conditions. That is, the consistency check should be selected on the known underground line, and the same signal is applied by using the same signal application in a single line of the known plane position and the depth, recorded, recorded, recorded The detection position and detection depth and the actual line position and depth of the detection depth are statistical. The underground pipeline detector verification can be carried out simultaneously with the probe method and should be in accordance with the following provisions: 1 Test site and test conditions should be representative and targeted; 2 tests should be carried out on the known pipeline segments within the measurement area; 3 Test should be carried out for different types, different materials, different depths of underground pipelines and different geophysical conditions; 4 to be put into use, different types of underground pipeline detectors should participate in test; 5 explore the test The content should include wave velocity measurement, antenna frequency, sampling frequency selection, etc.
7 All underground pipeline detectors positioning and deployment merges should meet the requirements of the relevant procedures. Various instruments that do not meet the requirements shall not be put into use. The above is the detection process before using the underground line detector.
