Abstract

In today's construction industry, pile foundation construction is one of the key technologies to ensure the stability and safety of buildings, and its construction quality directly affects the success or failure of the entire project. With the rapid development of urbanization and engineering technology, the requirements for pile foundation construction technology are also increasing. Therefore, it is of great significance to explore and solve common problems in pile foundation construction. This study first provides an overview of the types of pile foundations and pre construction preparations, followed by an in-depth analysis of key technologies in pile foundation construction, including geological exploration and pile type selection, accurate placement and verticality control of piles, and grouting and solidification techniques. The mastery and application of these key technologies directly affect the quality and efficiency of pile foundation construction. In terms of quality control in pile foundation construction, this study discusses in detail the standards and requirements for quality control, quality control measures during the construction process, and standards and methods for quality inspection and acceptance. In addition, this study proposes specific solutions to common problems in pile foundation construction, such as pile fracture and inclination, pile displacement and position errors, difficulty in pile sinking and resistance anomalies, substandard grouting quality and leakage, and insufficient floating and sinking of steel cages. These include strict control of pile driving speed and force, use of high-precision positioning equipment, selection of appropriate pile driving equipment, selection of appropriate grouting materials, and strengthening of the fixation of steel cages. This study summarizes the key technologies and solutions to common problems in pile foundation construction, and points out the shortcomings of the research and future prospects. I hope that the results of this study can provide some reference and inspiration for the field of pile foundation construction, and promote the healthy development of the construction industry.
