Principles of piling

Answer:

The structure of a pile driver consists of a pile hammer, a pile stand and auxiliary equipment. The pile hammer is attached to two parallel vertical guide rods (commonly called Longmen) at the front of the pile support and hoisted with lifting hooks. The pile foundation is a steel structure tower with a windlass at the back of which is used to lift the pile and hammer. A guide frame consisting of two guide rods is used in front of the pile to control the direction of the pile driving so that the pile can be accurately penetrated into the formation in accordance with the design orientation. The tower and the guide frame can be used to batter pile deflection. The guide frame can also be extended downward along the tower and used to fetch water along the embankment or pier. The pile can move and move. The basic technical parameters of a pile driver are impact weight, impact kinetic energy and impact frequency. According to the motion of the pile hammer power source can be divided into hammer, hammer, diesel hammer, hydraulic hammer etc..
Because of the buildings on the ground if you want to build on the ground, the ground will bear great pressure, we must ensure that the ground has enough resistance to stress strength, it is often difficult to do, so we must reinforce or improve the ground under way on the ground to bear, so I think in the pile foundation, make the most of the weight of buildings to the position below ground deep through the pile foundation, because this position is much larger than the ground bearing capacity.As to how deep the pile should be, it depends on the distribution of the ground beneath the ground (technically called the geological structure layer). If it is enough to withstand the pressure of the building, the pile hits here, and if not, it must continue to deepen.
