Abstract
The invention discloses a construction process of an argilloid geological ground network. The construction process comprises the following steps of 1, material preparation and site preparation; 2, measurement, positioning and groove digging; 3, vertical grounding body laying; 4, horizontal grounding body laying; 5, grounding system welding; 6, groove filling; 7, waterproof processing during a grounding leading-up line penetrating through a cushion layer; and 8, grounding resistance measurement, in which the 50-by-6 galvanized flat steel horizontal grounding body with length larger than or equal to 6 meters, the 50-by-50-by-5 vertical grounding body in 2,500 millimeters, a 50-by-6 horizontal pressure-sharing belt, a 50-by-6 galvanized flat steel grounding leading-out line and resistance reduction agent are prepared, a corresponding construction operating surface is ensured, the leveling of a base is completed, and check and acceptance are performed according to bearing capability of foundation pit. By the process, the resistance is favorable reduced, the corrosion-resistant capability is improved, the step voltage can be reduced, the personal safety is improved, water prevention isfacilitated, the excavation area of a plant is favorably reduced, and the construction cost is reduced.
Description
technical field [0001] The invention relates to the technical field of rock geological grounding grid construction technology, in particular to a construction technology of mudstone geological grounding grid. Background technique [0002] Lightning protection engineering is the most difficult and most important sub-item in construction. Due to the large differences in the design of grounding grids in different environments, the grounding engineering of the system is mainly composed of grounding bodies and connecting wires to form a grounding network, which affects grounding. Several factors of the effect are soil resistivity, anti-corrosion of grounding material and reasonable layout of grounding network. Since the grounding grid is easily overlooked as a concealed project, people often only pay attention to the final grounding resistance measurement results. When the grounding resistance measurement results do not meet the requirements, it is easy to cause rework and increa...
