In the process of strengthening municipal bridge pier columns, first of all, it is necessary to have a certain understanding of the causes and damage degree of the large-scale deviation of the municipal bridge pier columns; Secondly, the old bridge pier needs to be drilled horizontally and reinforced, and the old bridge pier is surrounded by steel plates to improve the compression resistance of the pier; Third, when the pier body is surrounded by steel plates, brackets are installed on both sides, and the old pier formwork is poured with concrete, which not only greatly improves the compression resistance and seismic resistance of the old pier column. At the same time, it can also increase the surrounding columns of concrete reinforcement, and greatly improve the stability of the pier.

Considering the particularity of technology in the construction process, in the process of strengthening municipal bridge piers and columns, we should start with the current actual situation of municipal bridge piers and columns. Analyze the technical form of the reinforcement of pier columns of municipal bridges, and carry out the reinforcement work according to the demand for reinforcement ratio.

Increase cross-section reinforcement method

In the process of strengthening the pillars of municipal bridges, a commonly used technique is to increase the cross-sectional reinforcement method. The cross-section reinforcement method is to expand the cross-section of the bridge pier by adding concrete and reinforcing steel on the basis of the old structure of the municipal pier, so that the pier can enhance its own compression resistance and seismic resistance. In the process of reinforcement, different cross-sections need to be reinforced according to different pier columns. During the construction process, different treatments need to be made according to the actual conditions of the pier columns, and the choice of concrete is also different.

For the variable-pull zone of pier columns, the compression capacity of the pier columns can be increased by adding components, and the seismic level of the members can also be improved. This construction method is relatively complicated in the actual operation process, and it needs to be prepared in advance, such as pay-off.

Steel plate reinforcement technology

In the process of operating the municipal bridge pier column, the reinforcement treatment can be used to compare the municipal bridge pier column. The steel plate reinforcement method is a commonly used reinforcement technology in the municipal bridge pier column. The adhesive paste is applied to the municipal bridge pier column. The steel plates of different sizes are pasted on the surface of the pier column, so that the steel plate and the pier column form a unified force. Considering that different structures require different reinforcement technologies, they need to play a role in the reinforcement stage.

When reinforcing components with large eccentricities, the reinforcement process needs to be positioned according to the specific operating specifications of the reinforcement steel plate bonding technology.

Carbon fiber sheet reinforcement technology

The technology of sticking carbon fiber is obviously the more technical means currently used in the reinforcement of municipal bridge piers. The use of carbon fiber technology can better strengthen the bridge piers. This type of technology is similar to the method of using pasteboard reinforcement. The use of carbon fiber technology has the characteristics of light weight, while also ensuring the characteristics of high strength and strong corrosion resistance.

When strengthening municipal bridge piers, first of all, we need to have a full understanding of various types of information on municipal bridge piers and columns, and secondly observe whether the concrete is deformed or not. Through the reinforcement technology, the compressive and seismic capabilities of bridge piers and columns can be improved. In the process of transverse treatment, the use of carbon fiber technology can increase its binding force, and at the same time it can well deal with the downward trend of the strain curve, improve the compression capacity of the bridge pier, and achieve the purpose of ductility.

The city bridge pier column reinforcement technology is a core work in bridge engineering. The city bridge pier column reinforcement is the reinforcement work carried out on the basis of retaining the original dismissal. Some adverse factors may appear during the construction process. Therefore, in the process of strengthening the city's bridge piers and columns, it is necessary to increase the durability of the city's bridge piers and columns, and at the same time improve the compressive and seismic capabilities.
