独立基础在工业与民用建筑中已得到广泛应用。这种基础在施工中放线、捻线稍不注意就很容易超过允许偏差。我公司在某厂大型成品库的施工中,已灌筑完毕的一条纵轴线上的15个杯形基础中心线对定位轴线的位移达450mm。为了避免重大损失,我们采用了顶进技术,使重达38.8t的15个独立基础按期移到了设计位置,不仅保证了工程进度,而且避免了近5万元的直接损失。现将我们的一些做法简介如下: 一、顶进的原理利用顶进技术对独立基础进行位置纠偏的原理是:使挖去了四周土方的独立基础在
The independent foundation has been widely used in industrial and civil construction. This type of foundation can easily exceed the allowable deviation when the line is put on during construction and the squatting line is not noticed. In the construction of a large-scale finished product warehouse of our company, the displacement of the 15 cup-shaped basic centerlines on the longitudinal axis of the company’s completed longitudinal axis has reached 450mm. In order to avoid major losses, we have adopted the jacking-in technique to move the 15 independent bases weighing up to 38.8 tons to design positions on schedule, which not only guarantees the progress of the project, but also avoids the direct loss of nearly 50,000 yuan. Now we introduce some of our practices as follows: First, the principle of jacking The principle of using the jacking technique to correct the position of an independent foundation is to make it possible to dig the independent foundations around the earth.
