Problems solved by technology

[0004] The existing factory grounding construction method cannot reduce the resistance well, has low corrosion resistance, cannot reduce the step voltage, and reduces personal safety. At the same time, it does not have a good anti-seepage ability, which is not conducive to rust prevention. This defect, so it is necessary for us to design a construction method of mudstone geological grounding grid

Abstract

The invention discloses a construction method for a mud rock geological grounding grid. The method comprises the following steps that 1, materials are prepared, and field preparation is conducted; 2,measurement and positioning are conducted, and grooves are dug; 3, vertical grounding bodies are laid; 4, horizontal grounding bodies are laid; 5, a grounding system is welded; 6, the grooves are backfilled; 7, a grounding outgoing line is prepared; 8, the grounding outgoing line is connected with a grounding busbar; 9, the grounding resistance is measured. The 50*6 galvanized flat steel horizontal grounding bodies with the lengths larger than or equal to 6 m, the 50*50*5 vertical grounding bodies with the lengths of 2,500 mm, 100 mm*100 mm*10 mm Q235 galvanized steel plates and the 50 mm*5 mmT2 purple flat steel grounding outgoing line are prepared and subjected to foundation pit bearing capacity inspection and acceptance. The method helps to well lower the resistance and improve the anti-corrosion capacity, the step voltage can be lowered, the personal safety coefficient is increased, the good water penetration prevention capacity is achieved at the same time, and the method is beneficial to rust prevention.

Description

technical field [0001] The invention relates to the technical field of mudstone geological grounding grid construction, in particular to a mudstone geological grounding grid construction method. Background technique [0002] Lightning protection engineering is the most difficult and important sub-item in construction. Due to the 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, the anti-corrosion of the grounding material to choose the grounding material and the reasonable layout of the grounding network. Because the grounding grid is easily overlooked as a concealed project, only the final grounding resistance measurement result is often paid attention to. When the grounding resistance measurement result does not meet the requirements, it is easy to ...
