　　d、 Expansion head construction: The expansion head construction first requires support, which adopts the "grouting curtain anchor rod wall protection technology". Excavation of enlarged head soil can only be carried out after the support is completed. During the construction of the enlarged head support, it is required to form inclined anchor holes at the design position according to the design angle, spacing, etc; After the completion of the inclined hole of the anchor rod, a triangular steel cage is placed underneath.

　　LED fluorescent lamps do not contain any toxic substances, do not cause damage to the environment, do not produce electromagnetic interference, and are a completely green, environmentally friendly, and pollution-free light source. Fluorescent lamps contain mercury. A 36mm fluorescent lamp contains 25-45mg of mercury, while a 26mm (T8) lamp contains 20mg of mercury. Fluorescent lamps use fragile glass as the outer shell. Once the glass breaks, the mercury in it will immediately evaporate into the air, instantly causing the mercury concentration in the surrounding air to reach 10-20 milligrams per cubic meter, exceeding the national standard of 1000-2000 times. Mercury is a toxic substance that is very harmful to the human body. When the mercury vapor reaches 0.04 to 3 milligrams, it can cause chronic poisoning in humans for 2 to 3 months. When it reaches 1.2 to 8.5 milligrams, it can induce acute mercury poisoning. If the amount reaches 20 milligrams, it can directly lead to animal death. And 1mg of mercury is enough to contaminate 5454.5 kilograms of drinking water, making it unable to meet drinking standards. The assembly parts of LED lights can be easily disassembled and can be recycled through other channels without the need for manufacturers to recycle them.
