Pile soil load adjuster used for composite pile foundation

Abstract

The invention discloses a pile soil load adjuster used for a composite pile foundation. The pile soil load adjuster comprises an upper end plate, a lower end plate, an upper protection barrel, a lowerprotection barrel and bevel plate parts. The two ends of each bevel plate part are connected to the bottom of the upper end plate and the top of the lower end plate correspondingly. The upper protection barrel is mounted on the lower end face of the upper end plate. The lower protection barrel is mounted on the upper end face of the lower end plate. During use, the load adjuster is mounted between a bearing table and the pile top of an end bearing pile, the load adjuster is provided with the bevel plate parts, the bevel plate parts already have a certain deformation angle, the pressing deformation direction of the bevel plate parts is controllable, and therefore the pressing deformation curve of the load adjuster is stable and accurate; and when the composite pile foundation is designed and calculated through the set pressing deformation curve of the load adjuster, the vertical load of the pile top is effectively controlled, the design thought is clear, stress is clear, the share proportion of pile soil can be effectively adjusted, and calculation accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of non-soft ground composite pile foundations, in particular to a pile-soil load regulator for composite pile foundations. Background technique [0002] Pile foundations usually include conventional pile foundations and composite pile foundations; in the design and calculation of conventional pile foundations, the bearing capacity of a single pile is taken as the characteristic value or design value, regardless of the bearing performance of the soil around the pile, and the load of the superstructure is completely borne by the pile; The composite pile foundation is a sparsely arranged pile foundation form, which can make full use of the bearing capacity of the soil around the pile. Compared with the conventional pile foundation, the amount of piles used in the project is greatly reduced, which can greatly save cost investment. [0003] In the existing composite pile foundation, a load regulator is usually in...

Problems solved by technology

[0005] However, through observation, it is found that the compression deformation of the existing load regulator is torsional knee-bending deformation, which is still an uncertain deformation, and the compression deformation curve of the load regulator is uncertain, which leads to There is still a large error
