Some topics on using ultrasonic method for concrete casting level measurement in bored pile foundation
With the high-speed increase of Chinese economy, bored piles are widely used in infrastructure construction projects. But how to gain the exact surface of the casting concrete is a difficult problem in quality control for bored pile. In practice, the only way to avoid quality problems is to cast more volume of concrete, this makes a great waste and gives great pressure on environment for the discard concrete columns. So, develop an ultrasonic device to measure the concrete casting level is of vital importance. Based on analysis the negative impacts by casting too much concrete, the paper presents the design scheme for the device, introduces the main difficulties and summarizes the main up-to-date gains by our group.
