Pile foundation bearing force detecting system and method

Abstract

The invention relates to a pile foundation bearing force detecting system comprising a fixing sleeve, inner bushings, a cover plate, a supporting column, an upper supporting frame and lifting mechanisms. The fixing sleeve and the inner bushings are each in a hollow cylindrical structure, the inner bushing are sequentially sleeved with the hollow structure of the fixing sleeve, the cover plate is mounted on the top of the fixing sleeve, the upper supporting frame is mounted on the top of the cover plate through the supporting column, and the left and right sides of the lower end of the fixing sleeve are each provided with one lifting mechanism; and the fixing sleeve is matched with different number of inner bushings to form different inner diameter dimensions, so that the pile foundation bearing force detecting system can detect the bearing capacity of different pile foundations. The pile foundation bearing force detecting system can solve the problems that when different pile foundations are detected, the pile foundation load bearing frame inner diameter adjustment is complex, a bearing frame cannot be attached to the pile foundations when placed on the tops of the pile foundationsin a sleeving manner, and the detection effect of the pile foundations is influenced by the phenomena that the hidden danger of rollover exists on the bearing frame and manual placement on the bearing frame can cause uneven pile foundation stress are solved.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a system and method for detecting the bearing capacity of pile foundations. Background technique [0002] The deep foundation composed of piles and pile caps connected to the top of the pile or the single pile foundation connected by columns and pile foundations is called pile foundation for short; in modern high-rise buildings, pile foundations are widely used, and high-rise building pile foundations are usually low-bearing Platform pile foundation, low cap pile foundation is that the pile body is completely buried in the soil, and the bottom surface of the cap is in contact with the soil. [0003] The bearing capacity of the pile foundation needs to be tested after the construction is completed. The bearing capacity of the existing pile foundation is generally detected by the static load detection method. After a heavy object is hoisted on the upper end of the pile foundat...

AI Technical Summary

Problems solved by technology

[0004] 1. When the load is manually applied to the pile foundation, it is necessary to place a support bracket on the upper end of the pile foundation. When testing the load force for different types of pile foundations, the steps to adjust the size of the support bracket are cumbersome, and the support bracket is placed on the The top of the pile foundation cannot be fitted with the pile foundation, resulting in the hidden danger of rollover of the bearing bracket;

[0005] 2. When the load is manually placed on the support frame, the force of the pile foundation will be uneven, which will affect the detection effect of the pile foundation
