Abstract:

Planted piling is a low noise and low vibration piling method, which is currently widely used in Taiwan. This technology has many advantages, including high bearing capacity, quick construction speed, easy controlling of construction quality and no second environmental damage. This paper introduces two construction methods of prebored planted piles and compares the benefits of the two construction methods by using such evaluating factors as the recovery rate of coring, the uniaxial compression strength, the ultimate bearing capacity of pile and the construction speed. The comparison results show that the traditional construction method of prebored planted pile is better for its rapid construction speed and economic efficiency.

Key words: prebored planted pile, core sample, pile loading test, construction speed
