Repairing method of damaged foundation pile of high-pile wharf

Abstract

The invention discloses a repairing method of a damaged foundation pile of a high-pile wharf and a pre-pile-adding force jacking system applied in the method. A jacking mechanism in the pre-pile-adding force jacking system is utilized to provide pre-pile-adding force for the whole system to transfer self gravity of the upper portion of the damaged section of the damaged foundation pile to the non-damaged foundation piles on two sides to enable the damaged section of the damaged foundation pile to deviate from the upper portion structure. In addition, the pre-pile-adding force jacking system is flexible in assembly and disassembly due to the fact that the system is of a beam system structure connected through a steel bar. The repairing method is reasonable in structure design, is capable of maintaining and processing the damaged section of the foundation pile under the condition that the upper structure of the damaged section of the foundation pile is not damaged, can achieve maintaining of the damaged section of the foundation pile in small space, and has small interference on normal working of other parts of the wharf.

Description

technical field [0001] The invention relates to the field of wharf maintenance and reinforcement, in particular to a method for repairing damaged foundation piles of a high-pile wharf. Background technique [0002] At present, due to the out-of-control ship hitting the berthing structure at the front of the high-piled wharf, the foundation piles at the front of the high-piled wharf are sheared and broken at the top of the pile, resulting in damage to the foundation piles of the high-piled wharf. There are two main types of repairs for this accident Methods, one is to use the pile supplement scheme, and the other is the pile connection scheme. [0003] The superstructure of the high-piled wharf will inevitably be damaged by the supplementary pile scheme, and because the position of the pile-pile is limited, this method needs to re-arrange the original high-piled wharf bent frame, which destroys the original design. The pile connection scheme is generally a method of setting ...

AI Technical Summary

Problems solved by technology

Both of the above two methods need to destroy the superstructure and then deal with the damaged pile foundation, which has the disadvantages of long construction period, large shoreline occupation, and great impact on wharf production.
