Types of Piles Based on Load Transfer, Installation Methods and Materials

If a bedrock or rocklike material is present at a site within a reasonable depth, piles can be extended to the rock surface. In this case, the ultimate bearing capacity of the pile depends entirely on the underlying material; thus the piles are called end or point bearing piles. In most of these cases the necessary length of the pile can be fairly well established. Instead of

Pile Foundation - Design, Construction and Factors Affecting Piles

In foundation practices, the main point of concern is bearing capacity of soil. Bearing capacity can be defined as the maximum load that can be carried by the soil strata. When the soil is strong enough that it can carry the whole load coming on it, then we use shallow foundation. Shallow foundations are usually used where hard soil strata is available at such a depth

Pile Driving Equipment - Pile Hammers

Piles are installed by a special pile driving device known as a pile hammer. The hammer may be suspended from the boom of a crawler crane, supported on a large frame called a pile driver or carried on a barge for construction in water.

Load Capacity Of Piles

Dynamic formulae are used for driven piles. Static formulae are used both for bored and driven piles. Load testing is the most reliable method to determine the load capacity of the pile in the field. They should be performed on all piling projects. However, they are considerably more expensive than the other methods used to determine pile capacity, and economic

Methods of Pile Installation

Piles are relatively long and slender members used to transmit foundation loads through soil strata of low bearing capacity to deeper soil or rock having a higher bearing capacity. The method by which this occurs is the basis of the simplest pile type classification. We have two main Pile Types (Classification of Piles): 1. End-Bearing piles, 2. Friction (or floating) piles
