Sample Time

Vibratory pile driving is a common application method of piles foundation construction. A test bed was designed and built according to the principle of vibratory pile driving. The test bed is composed of excitation system, machinery parts and signal acquisition system. At first soil samples with different relative compactness and different saturation were made. Then tests of vibratory pile driving have been done by using the soil samples and the test bed. For each soil sample, time of pile sinking to the bottom of the container was recorded respectively under the condition of the exciting force with same amplitude. The time represents efficiency of vibratory pile driving. The former is shorter and the latter is higher. Relationships between efficiency of vibratory pile driving and exciting frequency, relative compactness of soil, saturation of soil were researched respectively by single factor method. The experimental results have guide meaning to vibratory pile driving construction.

Vibratory Pile Driving

Factors directly affecting the penetration rate of piles installed by vibratory driving technique are summarized and classified into seven aspects which are driving force, resistance, vibratory amplitude, energy consumption, speeding up at the beginning, pile plumbness keeping, and slowing down at the end, from the mechanism and engineering practice of the vibratory pile driving. In order to find out how these factors affect the penetration rate of the pile in three major actors of vibratory pile driving: (i) the pile to be driven, (ii) the selected driving system, and (iii) the imposed soil conditions, field tests on steel sheet piles driven by vibratory driving technique in different soil conditions are conducted. The penetration rates of three different sheet pile types having up to four different lengths installed using two different vibratory driving systems are documented. Piles with different lengths and types driven with or without clutch have different penetration rates. The working parameters of vibratory hammer, such as driving force and vibratory amplitude, have great influences on the penetration rate of the pile, especially at the later stages of the sinking process. Penetration rate of piles driven in different soil conditions is uniform because of the different penetration resistance including shaft friction and toe resistance.
