Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of independent foundation, in particular to a method for using an independent foundation uneven settlement self-adjusting structure. BACKGROUND

[0002] Traditional independent foundation needs to excavate the ground to open a foundation pit, and then make a strip foundation as a wall foundation in the pit. This method often has more procedures and large earthwork, resulting in high time and cost. Therefore, if the shallow foundation is selected and the problem of uneven settlement of the foundation is solved, the cost will be lower (relative to pile foundation, raft foundation and cross foundation), and the application of column under independent foundation or strip foundation will be more widely used. We know that relying solely on increasing the rigidity of the foundation beam to resist uneven settlement of the independent foundation will significantly increase the cost, and this method often does not pay off. Therefore, it is of practical value to find a low-cost method to adjust uneven settlement. SUMMARY
