Abstract: Transducer can be used to detect the interface between concrete and slurry by detecting pressure along pipe. This interface is important to avoid pipe pulled out of concrete and good for cast-in place pile construction. But a lot of factors can affect the pressures on pipe. In order to detect pressure change around pipe and find out the reasons leading to pipe pressure changed, some factors such as density, pouring velocity, concrete temperature and concrete slump must be considered. By means of simulate cast-in place pile construction in library, pressure along pipe were detected. Results shows that density and pouring velocity are the main factors that can be effected on pipe pressure. Concrete temperature and slump are not outstanding factors. From differential pressure curve, interface position between concrete and air can be found.
