Vehicle-mounted mobile electrical resistivity detection system applicable to urban environment as well as working method

Abstract

The invention discloses a vehicle-mounted mobile electrical resistivity detection system applicable to an urban environment as well as a working method. The invention can realize lossless ground electrical resistivity exploration, flexibly arranges exploration survey lines by utilizing a vehicle-mounted manner, so as to realize arrangement of the detection system, and reduces stray and electricalsignal interference, so as to adapt to an urban complex noise environment. The detection system disclosed by the invention combines and gives play to advantages of a mobile vehicle-mounted system specific to engineering requirements in urban underground space development and construction processes, fully utilizes an urban road surface environment and improves operation efficiency.

Description

technical field [0001] The invention relates to a vehicle-mounted mobile resistivity detection system and working method suitable for urban environments. Background technique [0002] The development of urban underground space in China has grown rapidly. The development and utilization of urban underground space has become an important means for China to increase urban capacity, ease urban traffic, and improve the urban environment. It is becoming an important way to build resource-saving and environment-friendly cities. The development of urban underground space is generally located in the shallow part of the underground. During the construction of urban ground and underground space, it is very easy to induce geological disasters and threaten The safety of construction may even cause surface subsidence and foundation instability, which will affect the safety of people and facilities on the urban surface. [0003] In urban exploration, the resistivity method is sensitive to...

Problems solved by technology

[0006] Secondly, although the ground does not have large fluctuations in the urban environment, it is necessary to avoid artificial facilities such as ground buildings during detection and measurement, which makes the layout of the measurement network irregular; some old urban areas and most suburban areas have undulations, and the layout of the measurement network needs to consider the terrain Factors, it is difficult to arrange the test network regularly;

[0007] Finally, the urban environment resistivity detection is interfered by stray electrical signals with complex reasons, and in some special cases, it may face a large grounding resistance, which hinders the resistivity detection
