Environmental investigation is a typical "appearance" through "essence", it is through the investigation of the environment to find water leakage clues. Environmental investigation method refers to the visual observation of the topography and landscape environmental changes around the pipeline, the investigation of sewage, sewer, rainwater, electricity and other valve wells in the flow of clear water, to detect and analyze the leak clues. The core of environmental investigation is investigation and analysis, that is, by comparing with the surrounding environment, analysis, screening the authenticity of the clues and identifying the reliability of the clues.

What should the environmental investigation start with? According to the past experience of water leakage detection, environmental investigation should start from the following aspects.

1) Roadbed settlement, collapse, soft foundation (standing on the feeling of shaking).

2) Waterlogged, icy roads.

3) cracked ground, dampness, slight seepage, moss.

4) Unusually lush vegetation compared to surrounding areas.

5) ground that is hot and warm to the touch.

6) snow melting faster than in surrounding areas.

7) rain, sewage, drainage, cable, communication and other valve wells are clear water.

All of these signs can be used as suspicious clues. However, if you want to confirm the diagnosis of water leakage clues to further follow up the investigation, and the surrounding environment analysis and comparison, to identify the authenticity of the clues.

The most direct and effective way is to confirm whether the leak through the pipe leak detector

The working principle is that after the pressure water pipe leak pressure water from the pipe break out of the mouth, and the pipe wall friction generated by the sound vibration and caused by other additional vibration to the pipeline above the ground, with the pipeline leak detector in the road to detect, to find out the leak.

Generally speaking, the basic detection method is, connect the pipe leak detector good host, headphones, sensors. Turn on the switch, put on the headset, place the pipeline leak detector sensor on the road above the pipeline, placed step by step according to the length of the pace, step by step listening, the closer to the leak, the stronger the signal, the farther away from the leak the weaker the signal, by comparing the signal strength between different points to achieve the purpose of detecting leaks.

Environmental survey method of investigation of the clues is only an appearance, a clue, a possible, can not be used directly as a clue to the leak, but also through the "eye, ear, brain" trinity of diagnostic analysis, in order to eliminate false clues.
