Reinforcing and protection system and repair method of hydraulic pile

Abstract

The invention relates to a reinforcing and protection system and a repair method of a hydraulic pile. The system comprises a sleeve which surrounds a damage area of the pile, a sealing strip attached to the pile is arranged at the bottom of the sleeve, the inside, surrounding the damage area of the pile, of the sleeve is wrapped with a fiber grid, a stopper is arranged between the inside of the sleeve and the pile, and the space between the sleeve and the pile is filled with a slurry. The method is realized by the aid of the system. The construction is simple, the repair difficulty is effectively reduced, and the construction period is shortened.

Description

technical field [0001] The invention relates to the field of repair, reinforcement and protection of hydraulic structures, in particular to a reinforcement and protection system and repair method of hydraulic foundation piles. Background technique [0002] The foundation piles of the building structure are easily damaged by environmental corrosion, load, vibration and impact, which affect the partial or overall bearing function of the building. Especially in the environment of ocean, humid heat and corrosive water impact, foundation piles are prone to concrete cracking and spalling, aggregate loss, Reinforcement corrosion and other phenomena will reduce the bearing capacity of the pile foundation. Therefore, with the migration of time, it is often necessary to repair the foundation piles. [0003] At present, there are mainly five methods for the repair and protection of road and bridge foundation piles: pasting steel plates, pasting fiber composite materials, increasing t...

Problems solved by technology

However, when the method in the above-mentioned technology is used for underwater construction, there are defects such as the need for cofferdams and drainage operations, complex construction technology, long construction period, high construction cost, and short maintenance time.

[0004] In recent years, there have been domestic devices that use glass fiber sleeves to strengthen underwater piers, which are improved compared with traditional repair and reinforcement methods, but they have the following defects: complex support systems need to be installed, and glass fiber sleeves need to be prefabricated. The large volume occupied by the glass fiber sleeve makes installation and transportation inconvenient, it is difficult to achieve standardized production and supply after repeated mold opening, and the sealing and durability of the compression seal on the top are poor, etc.

Especially in the field of foundation pile reinforcement with large foundation piles, serious damage and high bearing strength requirements, it is difficult to meet the requirements
