> In recent years, with the continuous development of construction technology, people have paid more and more attention to the quality of urban environment. The construction of immersed pipe piles, rammed expanded piles, static pressure piles, deep mixing piles and some bored piles has caused noise, vibration, dust, mud sewage and high pollution. Due to cost and other reasons, they are gradually being replaced by long spiral dry-operated bored piles (pressure-grouted reinforced concrete piles and grouted reinforced concrete piles and piles). At the same time, because the long spiral process can achieve dry pile formation, the pile bearing capacity is high, and its construction quality is easy to ensure, the construction speed is fast and the cost is low, and other outstanding features are increasingly favored by the industry. The long spiral dry operation bored pile is a mechanical dry operation continuous hole-forming pile construction method without mud circulation. The drilling slag cut by the drill bit is continuously transported from the bottom of the hole to the surface through the spiral drill rod blades. Long spiral drilling construction method Strong adaptability to strata: suitable for filling clay soil, silt soil, sandy soil, garden gravel layer, pebble layer, strongly weathered rock and other strata
