Which company do you want to find for leak detection of municipal drainage pipeline?

Cctv detection of pipelines is a method to detect the internal conditions of pipelines and the health status of drainage pipelines.

Data collected before pipeline inspection:

I) Pipeline Plan

B), pipeline completion drawings and other technical data.

C) There are inspection data of pipelines.

Field survey data:

A) Check the geography, topography, traffic and pipeline distribution around the pipeline.

B) Visible water level, mud accumulation depth and water flow during well opening.

C) Check the pipeline position, pipe diameter and pipeline material in the data.

Determine the detection technical scheme:

A) Determine the purpose, scope and time limit of the test.

B) Carefully analyze and determine the detection technical scheme according to the existing data, including: how to block the pipeline, the method of cleaning the pipeline, how to solve the existing problems, and formulate safety measures.

Technical requirements for pipeline inspection before completion acceptance:

A) The pipeline shall be subjected to leak test, and the pipeline air tightness or water tightness test records shall be presented to the inspectors.

B) Before testing, ensure that the accumulated water in the pipeline does not exceed 5% of the pipe diameter.

C) Before the test, dredging, cleaning, ventilation and toxic and harmful gas test must be carried out;

Technical requirements before pipeline maintenance and inspection:

A) First, flush the pipeline to be tested.

B) Before inspection, ensure that the accumulated water in the pipeline cannot exceed 15% of the pipe diameter. If there is branch pipe running water, first block it to ensure that the image data recorded by the locomotive is clear and accurate.

C) Dredging, cleaning, ventilation and detection of toxic and harmful gases must be carried out before detection.

Zhongke Inspection has the inspection and evaluation service of underground drainage pipeline, and adopts the advanced cctv pipeline endoscope TV inspection system, which can automatically crawl in the pipeline and detect the rust layer, scaling corrosion, perforation and crack in the pipeline.
