Description

Technical Field

[0001] This utility model belongs to the field of port engineering, and in particular relates to a device for repairing and reinforcing the bottom of a high-pile wharf panel. Background Technology

[0002] Many high-pile harbor wharves built in the last century have experienced varying degrees of corrosion and damage to their reinforced concrete structures before reaching their designed structural service life.

[0003] The deck panels are the directly load-bearing components of the wharf surface, making them relatively prone to damage. While the cargo load on the wharf surface is relatively small, it is frequently subjected to flowing loads. Under the repeated action of these large flowing loads, the deck panel components are often susceptible to cracking, concrete spalling, and other damage. Coastal wharves are constantly exposed to a surface chloride ion corrosive environment, and the corrosion process of damaged components is irreversible, further exacerbating the damage to the deck panels and jeopardizing the safe use of the wharf.

[0004] Currently, conventional dock panel repair requires the construction of a platform, which disrupts the normal operation of the dock. There is currently no platform-free rapid repair technology or device suitable for dock panels. To ensure the structural safety of dock panels and extend their service life, there is an urgent need for a high-pile dock panel bottom repair and reinforcement device to repair and protect vulnerable panel areas. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a device for repairing and reinforcing the bottom of a high-pile wharf panel. This device is easy to use and can repair and reinforce damaged parts of the bottom of the wharf panel without affecting the normal use of the wharf.

[0006] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is: a device for repairing and reinforcing the bottom of a high-pile wharf panel, comprising multiple working units, the two ends of which are respectively connected to the bottom of the panel by a suspender rod.
