Objective During bored pile construction, precise control of the concrete pouring height is a critical factor in ensuring pile foundation quality. Existing studies indicate that traditional concrete pouring operations mainly rely on visual observation and ruler measurements to monitor the concrete height inside the borehole, which are greatly affected by the construction environment and generally suffer from insufficient measurement accuracy and poor real-time performance. This not only leads to material waste and increased construction costs, but may also pose hidden risks such as insufficient pile length. To address this issue, a method for measuring the pile top elevation during concrete pouring construction is investigated.

Method Based on Jiashan-Xitang Suburban Railway civil engineering construction project, and grounded in mechanical structure optimization design theory and detection technology, the overall structural design of a monitoring device is completed. This device overcomes the shortcoming of traditional measurement methods in terms of accuracy and real-time data acquisition, and a novel device capable of real-time and precise measurement of pile top elevation during bored pile construction is developed.

Result & Conclusion  Engineering applications verify the applicability and superiority of the pile top elevation monitoring device. The results show that the new monitoring device features high accuracy, low cost, and real-time monitoring capabilities, as well as simple operation and rapid installation. It accelerates construction progress, improves construction quality, and promotes the intelligent development of pile foundation engineering.
