MUNICIPAL SERVICES. UNDERGROUND COMMUNICATION EMERGENCY

Sewage Pipe in Permafrost (Yakutia)

Because of permafrost thawing of frozen soils, due to the penetration of warm waste water, there may be threats to the integrity of the foundations of nearby buildings. The purpose of GPR survey - definition of zones of thawing soil.

Figure 1 shows the result of the construction of the section of the real part of complex relative permittivity along the profile crossing the location of underground pipes break. In Figure 2 the blue arrow shows the position of the profile on the plan. The image of the section soil with temperatures below zero degrees Celsius appear yellow - red flowers. Thawed ground is represented blue - blue color scheme, and, the wetter the soil, the saturated blue. The section shows that most hydration accounts for the location of underground and breaking the greatest depth of thawing is about 4 meters:
