Pile foundation is a foundation construction that can withstand the force orthogonal to the center of the building by absorbing diffraction. Pile foundation was made into a single monolithic entity that unites the base of which there are piles and under construction with pedestal foundation.
Implementation of each sapling erection work is done by means of the diesel hammer. Working system of diesel hammer is a tool with a beating so that it can cause a loud noise and vibration in the surrounding areas. That is why the type of foundation piling into separate problems to the environment, not to mention a way to bring equipment into the diesel hammer piling foundations are commonly used to Tronton truck crane (to raise and lower the mast hydraulic piling hammer that weighed 3-7 tons.
a. Types of piles
Generally there are two kinds of piles of small (mini pile) and large size (maxi pile).
1) Miniipile (small size)
Small piles used for low-rise buildings and land is relatively good. Size and strength are offered are as follows:
1. sectional shape triangle: size 28 is able to sustain pressure of 25-30 tons burden and the size 32 that is able to sustain pressure of 35-40 tons burden.
2. square cross-section shape: size 20 x 20 that is able to sustain pressure load 30-35 tons and measuring 25 x 25 that is able to sustain pressure load 40-50 tons
2) Maxi pile (large size)
These piles are round (spun pile) or box (square pile), Its use for large load on high-rise buildings. In fact, for sizes 50 x 50 can support up to 500 tons burden.
