Abstract

With the rapid development of the domestic economy, the proportion of infrastructure investment is increasing. The number of bridges built in rivers, lakes, and reservoirs is increasing. The development direction of bridges is increasingly focused on deep foundations, high piers, and large spans. . For a single bridge, the basic construction technology and management work is a key part of the whole bridge construction, especially the construction of the underwater bridge foundation, which directly affects the investment benefit and risk control of the entire bridge construction. Today, bored piles are widely used in high-rise building foundation engineering. However, due to the complicated construction process of bored piles, the construction quality is often difficult to guarantee, especially the insufficient concrete strength of the underwater bored piles is a common quality problem. In this paper, the quality control measures for underwater bored pile construction of bridges are proposed.
