| 英文摘要 | In the early stage of concrete pouring of bored piles, the high-precision quality inspection of bored piles has become an important engineering and scientific problem to be studied and solved. Firstly, to solve the technical problems existing in the current testing equipment and methods, such as the scarcity of data, poor measurement accuracy, and low work efficiency, this paper proposes a solution that uses the combination of multiple arrays of ultrasonic waves to scan the borehole contour as the leader, and forms a multi-array ultrasonic scanning technology suitable for the quality inspection of bored piles. Subsequently, a multi-element horizontal section scanning model is proposed, which realizes the position and sound velocity correction in the horizontal section acoustic scanning process, which solves the technical problems, such as the inability to locate accurately due to the swing of the probe in the single element scanning process, and the inability to calibrate the sound velocity in real time. Finally, this paper proposes a borehole quality evaluation method based on multivariate scanning data, forming a borehole quality evaluation system for horizontal section and vertical section, which realizes the borehole quality evaluation of cast-in-place pile from local to global, and from profile to all-round. The feasibility and superiority of the technical methods in this paper are verified by experimental tests. The results show that this method can obtain more effective detection data of the borehole wall, and at the same time can accurately reflect and extract the characteristic parameters of the cast-in-place pile borehole quality, which can effectively solve the technical problems of limited scanning data and low measurement accuracy in the cast-in-place pile borehole quality detection. The method in this paper expands the function of borehole quality detection technology, and lays a foundation for solving the problem of accurately judging and evaluating the borehole quality of cast-in-place piles in practical projects, which has good application prospects and promotion value. |
