CFG pile bearing capacity detection structure and method

Abstract

The invention discloses a CFG pile bearing capacity detection structure and method. The CFG pile bearing capacity detection structure comprises a first pile body, a second pile body, a third pile body and a bearing part which are sequentially arranged, wherein, the bearing part stretches across the second pile body, the first end of the bearing part is fixed to the first pile body, the second end of the bearing part is fixed to the third pile body, a jack is fixed between the bearing part and the second pile body, the jacking end of the jack is connected with the second pile body, and the base end of the jack is connected with the bearing part. The structure and the method solve the problems that in the related art, the detection structure needs a large number of balancing weights and bearing supports, a crane is needed for cooperative operation, the manufacturing cost is high, prepressing blocks are difficult to transfer, safety is poor, and falling and collapse are prone to occurring due to misoperation are solved. The manufacturing cost is high, and the prepressing blocks are difficult to transfer; The safety is poor, and falling and collapsing are prone to occurring due to improper operation.

Description

technical field [0001] This application relates to the field of subgrade engineering construction, in particular, to a CFG pile bearing capacity detection structure and detection method. Background technique [0002] CFG pile is a commonly used construction technology to deal with insufficient bearing capacity of weak foundations. It is widely used in engineering because of its advantages of simple operation and good reinforcement effect. Generally, after its construction is completed and its strength reaches stability, it is necessary to conduct a single pile bearing capacity test and a composite foundation bearing capacity test. [0003] The traditional detection method is the bracket load-bearing method, the lower part is equipped with a jack, and the upper part is equipped with load-bearing beams, distribution beams, pre-loaded blocks and other devices. The principle of action is to transfer the weight of the upper pre-compression block to the lower jack, and transfer t...
