现代城市建设的飞速发展,令城市建设用地越来越受限制,特别是在市区中心或旧城改造地区,因受周围已有建筑物的限制,受环保要求的限制,对新建筑物基础的施工方式有了更高的要求。这种施工方式既要满足结构本身对基础强度、承载力的要求,又要满足施工时振动小、噪音低的环保要求。所以,与这种要求相适应的钻孔灌注桩的运用已日益增多。 一、钻孔灌注桩的工作特点 钻孔灌注桩与预制桩相比,没有破桩
The rapid development of modern urban construction has made urban construction land more and more restricted, especially in the urban center or the transformation of the old city, due to the restrictions of existing buildings, environmental protection requirements, and the foundation of new buildings. The construction method has higher requirements. This construction method must not only meet the requirements of the structure itself on the basic strength and bearing capacity, but also meet the environmental protection requirements of low vibration and low noise during construction. Therefore, the use of bored cast-in-place piles adapted to this requirement has increased. First, the working characteristics of bored piles Compared to prefabricated piles, bored piles have no broken piles.
