A device and implementation method for self-generating protection of steel bars in pile foundations of high-piled wharves

Abstract

The invention discloses a device for protecting reinforced bars in a high-pile wharf pile foundation by self power generation and an implementing method. The device is characterized by comprising a wave power generation module (2) and a tidal level power generation module (3), wherein the wave power generation module (2) and the tidal level power generation module (3) are arranged on a high-pile wharf pile foundation (1). The device for protecting the reinforced bars in the high-pile wharf pile foundation by self power generation and the implementing method have the advantages that the interactive type uninterrupted self power generation is realized by the wave power generation module and the tidal level power generation module, the power is generated by the change of wave and tidal level, the additional applying of current is not needed, the new energy source is utilized at high efficiency, the energy-saving, emission-reduction and low-carbon effects are realized, the reliability is high, the automation degree is high, the manual maintenance is simple and convenient, and the applicability is wide.

Description

technical field [0001] The present invention relates to a device and implementation method for self-generating protection of steel bars in pile foundations of high-pile wharves, in particular to a device and implementation method for self-generation protection of steel bars in pile foundations of high-pile wharfs under water level changes, and is suitable for port construction External DC power supply protection for middle and high pile reinforcement. Background technique [0002] The high-piled wharf is one of the important fixed wharf structure types in port engineering buildings, and it is widely used in our country. Due to the influence of factors such as its own structure and marine working environment, the durability of the high-piled wharf is poor, and the corrosion of steel bars is the main reason for its reduced reliability and short service life. Because the pile foundation has been in an environment where the water level is constantly changing and the dry and wet...

Problems solved by technology

Due to the influence of factors such as its own structure and marine working environment, the durability of the high-piled wharf is poor, and the corrosion of steel bars is the main reason for its reduced reliability and short service life

Because the pile foundation has been in an environment where the water level is constantly changing and the dry and wet alternately, the steel bars in the pile foundation of the high-pile wharf will corrode prematurely, and the corrosion of the steel bars will directly lead to a great decline in the bearing capacity of the pile foundation, which will cause a huge Reduced dock lifespan

[0003] According to the research status at home and abroad, the protection technology of external DC power supply has been proved to be a more effective protection technology against steel corrosion. However, the traditional steel protection system cannot generate electricity by itself and needs to be protected by external current, which will generate a large number of At the same time, the power consumption is exhausted after a period of use, and energy equipment needs to be replaced regularly, which increases the maintenance cost in the later period, which will bring greater capital investment

[0004] This makes the automation of the traditional reinforcement protection system poor, so there is an urgent need for a device that does not require external current, can generate electricity by itself, and can protect the reinforcement of the pile foundation.
