Construction method for increasing rock-socketed depth of large-diameter cast-in-place pile
The invention relates to the technical field of geotechnical engineering foundation pit supporting and construction, and particularly discloses a construction method for improving the rock-socketed depth of a large-diameter cast-in-place pile, which comprises the steps of sound wave measurement and prediction, prestressed cast-in-place pile design, sound wave guide drilling, prestressed pouring, prestressed tensioning and construction quality inspection. The rock stratum is analyzed through the sound wave measurement technology, the condition of the rock stratum is determined more accurately, a more accurate cast-in-place pile design scheme and construction parameters can be formulated, the cast-in-place pile is designed and reinforced through the prestress technology, the ultrasonic vibration reinforcing technology is applied in the cast-in-place pile construction process, and the construction quality of the cast-in-place pile is improved. The combination force between concrete and a rock stratum can be enhanced, the stability and the bearing capacity of the cast-in-place pile are improved, the rock-socketed depth of the large-diameter cast-in-place pile can be effectively increased by optimizing design and construction parameters, combining analysis of sound wave measurement on the rock stratum and applying the prestress technology and ultrasonic vibration, and the construction efficiency is improved. And the penetrating power and the pulling resistance of the concrete in a rock stratum are enhanced.
