[0047] In another embodiment, the green tile roof lightning protection structure further comprises:

[0048] The grounding device 7 is laid underground near the outer wall of the eaves. The grounding device 7 is made of galvanized flat steel with a width of 40 mm and a thickness of 4 mm, and a buried depth of 0.5 m. A gelled resistor layer is poured around the grounding device 7.

[0049] In the above implementation scheme, each down conductor needs to be electrically connected to the grounding device 7. For green-tiled buildings built on the mountain, such as the mountainous terrain of Chongqing, the main street of the site runs through the north and south, and several east-west trails are intertwined to form a spatial pattern of mountain streets, lanes, and courtyards. There is a large drop on the west side, and the terrain on the east side is undulating. The characteristics of adapting to local conditions form a scattered spatial layout, and the stepped trails connect the various buildings. This terrain and geological condition is very unfavorable for laying artificial grounding electrodes. First, the plane area of ​​the building monomer is small, which cannot meet the length requirement of the artificial grounding electrode; secondly, the sand and gravel content of the mountain soil is large, and the average soil resistivity is about 33 ohms. The resistivity is high, which is not conducive to the dispersion of the grounding conductor to the earth. According to the test grounding resistance of the building lightning protection foundation grounding device, it generally does not exceed 1 ohm. meter. Therefore, the soil resistivity must reach 1 ohm. meter or less to make the entire ground network reach the designed grounding resistance value. Therefore, a gelling resistor is poured around the grounding device 7 to form a gelling resistor layer. The soil resistivity must reach 1 ohm. meter or less. In this real-time solution, the gelling resistor uses the existing gj-f gelling resistor (whose main components are graphite and metal molecules as the main conductive materials, and a resistance-reducing material composed of gelling materials). The gelling resistance reducing agent is a liquid when poured. It has a strong penetration ability to the soil, is easy to produce a tree root effect, and can effectively increase the area of ​​the grounding body. After solidification, it becomes a colloid, which can wrap the grounding electrode well, prevent air from entering and causing corrosion, and better disperse the flow. The conductivity of the gelling resistance reducing agent is not affected by changes in acid, alkali, salt, temperature, etc. It has good moisture absorption, moisture retention, and antifreeze functions. It will not be lost due to the presence of groundwater, and has a long-term improvement effect on soil resistivity. The gelling resistance reducing agent has a strong anti-corrosion ability, a pH value between 7-8, neutral to alkaline, and has a passive corrosion protection and covering protection effect on the grounding body, which can effectively prevent aerobic corrosion. The specific process includes: excavation of the grounding device trench, deployment of the resistance reducing agent, laying of the grounding device, and pouring of the resistance reducing agent.
