Groundwater Exploration of Construction in Wells and Lanes
Groundwater exploration is the most important part of construction in wells and lanes. As an important resource material, groundwater exploration is the basis for groundwater development and utilization. The following is a description of the groundwater exploration of construction in wells and lanes.
Groundwater exploration consists of geological and hydrological geological investigation. The geological investigation includes the types of rocks, their lithology characteristics, physical-chemical indexes, content of pollutants and vein characteristics. According to the above information and the geological theory of groundwater, hydrogeological prospecting agents can roughly determine the groundwater hydraulic environment, the range of distribution and the formation characteristics of the aquifer group.
Hydrological exploration is to investigate the hydrogeological environment of wells and lanes and to collect and analyze the data of water depth and water level changes in the boreholes. According to the monitoring data of water depth and water level changes, the specific parameters of regional hydrogeology and the characteristics of regional hydrogeology can be studied.
Geophysical exploration is the investigation of the physical properties of the earths surface by measuring the electrical, magnetic or acoustic signals in the earth. This method can provide powerful graphical information and quantitative parameters of the groundwater exploration. Commonly used geophysical exploration methods include drilling, gravity, electromagnetism and seismic method, mainly used in deep wells and large engineering projects.
Water chemistry exploration is to investigate and analyze the characteristics of water through sampling at different depths in the wells, carrying out the assessment and analysis of static water level, water content, pH value and other related parameters in order to find out the geochemical characteristics of the underground environment.
The above is the description of the groundwater exploration of construction in wells and lanes. By conducting various explorations, the dynamic changes of groundwater can be monitored timely, so as to ensure the safety of engineering constructions. In addition, it helps to determine the layout of wells and lanes and decide the parameters for design and construction according to the characteristics of hydrogeological environment. It also helps to evaluate the environment impact caused by the construction and make corresponding countermeasures.
