I. Introduction.
Piling is one of the common construction methods in construction engineering, and its purpose is to push piles deep into the ground to support the building.
However, due to long-term exposure to the underground environment, piles are susceptible to corrosion and damage.
In order to prolong the service life of the piles and improve the stability of the building, the engineers came out with the FRP anti-corrosion layer of the piles.
Second, the characteristics of the FRP anti-corrosion layer of the pile.
Pile FRP anti-corrosion layer is a kind of anti-corrosion layer using fiber reinforced plastic (FRP) as the material, which has the following characteristics:
1.Corrosion resistance: Because FRP material has excellent corrosion resistance, it can resist the erosion of corrosive substances such as acid and alkali, salt water, etc., so as to protect the pile from corrosion.
2.High strength: FRP material has high strength and can withstand large pressure and tensile force, thereby increasing the stability and bearing capacity of the pile.
3.Lightweight: Compared with the traditional anti-corrosion layer material, FRP material is lighter, which reduces the weight of the pile and is convenient for construction and transportation.
4.Easy construction: The FRP anti-corrosion layer of the pile can be made into different shapes and sizes according to the shape of the pile, which is convenient for the construction personnel to install and maintain.
Third, the application of FRP anti-corrosion layer for piles.
Pile FRP anticorrosive layer is widely used in various construction projects, especially in areas with harsh marine environment and acid and alkali environment.
It can be used for various types of piles, including reinforced concrete piles, prestressed piles, steel pipe piles, etc.
The FRP anti-corrosion layer of the pile can effectively protect the pile from corrosion, prolong the service life of the pile and improve the stability of the building.
Fourth, the construction method of the FRP anti-corrosion layer of the pile.
The construction method of the FRP anticorrosive layer of the pile is relatively simple, which mainly includes the following steps:
1.Cleaning the surface of the pile: First of all, the dust and impurities on the surface of the pile need to be cleaned, and the FRP material can be in full contact with the surface of the pile.
2.Adhesive application: A layer of adhesive is applied to the surface of the pile to increase the adhesion between the anti-corrosion layer and the pile.
3.Install FRP anti-corrosion layer: Put the pre-made FRP anti-corrosion layer on the pile to ensure that the surface of the pile is completely covered.
4.Fix the anti-corrosion layer: use wire ropes, bolts and other tools to fix the anti-corrosion layer on the pile to ensure that the anti-corrosion layer will not fall off due to external force.
5.Coating anti-corrosion coating: Coating a layer of anti-corrosion coating on the FRP anti-corrosion layer to increase the corrosion resistance of the anti-corrosion layer.
V. Conclusions. Pile FRP anti-corrosion layer is an anti-corrosion material that effectively protects the pile from corrosion.
It has the characteristics of corrosion resistance, high strength, light weight and easy construction.
It is widely used in construction projects, which can extend the service life of piles and improve the stability of buildings.
The construction method is simple and can be completed in just a few steps.
