In order to ensure the structural safety of the highways and bridges under its jurisdiction, prevent flood season and long-term operational safety risks, the professional organization of China Airlines Branch recently conducted special inspections on the underwater pile foundations of key water crossing bridges.

In modern transportation networks, bridges serve as important transportation hubs, bearing enormous traffic flow and loads. The safety of bridges spanning rivers from bustling streets in cities to small bridges connecting the two sides of winding highways in mountainous areas directly affects people's travel safety and the stable development of the economy. Therefore, bridge inspection, as an important means of ensuring bridge safety, has crucial significance.

The operation time of water crossing bridges is relatively long, and the underwater pile foundation is easily affected by water flow erosion, water quality erosion, riverbed changes, etc., which can easily cause hidden diseases such as concrete peeling and steel corrosion. These types of diseases are difficult to detect through daily inspections, but they directly threaten the bearing capacity and structural stability of bridges, posing safety hazards. In this inspection, a professional technical team used advanced technologies such as underwater high-definition cameras, sonar detection, and diving exploration to conduct a comprehensive inspection of bridge piers, abutments, and underwater pile foundations. The inspectors focus on investigating the depth of riverbed erosion, pile damage, cracks, and other issues around the pile foundation. They keep good records of data and collect images throughout the process, synchronize the "one bridge, one file" disease database, and achieve accurate identification of hidden dangers.

Through the underwater inspection of divers, it is possible to penetrate the cover of water bodies, identify hidden diseases of pile foundations, detect defects and damages, corrosion, erosion of surrounding riverbeds, and the connection between pile columns, etc., to determine the bearing capacity of pile foundations and provide direct basis for the safe operation of structures.Bridge Underwater Pile Foundation Special Inspection Company - No charge for unsatisfactory underwater foundation inspection of highway bridge piers

The safe operation of bridges relies on the stable support of underwater pile foundations. As the "foot" of bridges, underwater pile foundations are the key concealed engineering that supports the entire structure. Due to being in an underwater environment for a long time, the true condition of the pile foundation is obscured by layers of water, making it difficult for conventional detection methods to reach. Once problems such as cracks, exposed reinforcement, and corrosion occur, if not detected in a timely manner, it may become a hidden danger to the safety of the bridge. Therefore, underwater pile foundation testing can be regarded as a "key link" in bridge safety management. Only through professional diving testing can the water barrier be penetrated and the "healthy foundation" of the pile foundation be determined.

The importance of bridge inspection is self-evident. It can not only timely detect safety hazards in bridges, prevent major accidents such as bridge collapse, and ensure the safety of people's lives and property; Reasonable maintenance and repair can also extend the service life of bridges and reduce their full lifecycle costs. For example, by regularly detecting and repairing minor defects in bridges in a timely manner, we can prevent them from developing into major problems, thereby reducing the cost of large-scale maintenance and reconstruction. At the same time, the data accumulated by bridge inspection also provides valuable practical experience for the design, construction, and scientific research of bridges, which helps to promote the continuous progress of bridge engineering technology.

This special inspection provides scientific support for the subsequent preventive maintenance, repair and reinforcement of bridges.
