随着我国四化建设的日益发展,高层建筑大量涌现,不仅对基础工程的需求量与日俱增,同时对工程质量也提出了更高的要求。灌注桩,特别是钻孔灌注桩,因其具有施工速度快、成本低、工程质量高、承载力大,安全可靠等优点,目前已被广泛应用到建筑、桥梁,坝基、厂房等领域,成为倍受欢迎的一种深基础工程。众所周知,百年大计,质量第一。灌注桩质量是关系着高层建筑的使用寿命问题,
With the increasing development of China’s four modernizations, high-rise buildings have emerged in large numbers. Not only do the demands for basic projects increase, but also higher requirements are placed on project quality. Cast-in-place piles, especially cast-in-place bored piles, have been widely used in construction, bridges, dam foundations, and factory buildings due to their advantages of fast construction speed, low cost, high project quality, large bearing capacity, and safety and reliability. A popular deep-rooted project. As we all know, one hundred years plan, quality first. The quality of cast-in-place piles is related to the service life of high-rise buildings.
