Principles of piling

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..

What are the parts of a pile driver?

The two guiding rods are omitted, and the plunger is a hammer head, which can move up and down in the cylinder. When piling, the pile cap at the bottom of the hammer block is pressed on the top of the pile, lifting the plunger with a hook, and then decoupling and downward impacting to compress the air enclosed in the cylinder. And fuel injection, explosion, shock, ventilation and other work processes. Diesel hammer work is on compression ignition diesel to start, it is necessary to ensure the closed gas cylinder reaches a certain compression ratio, sometimes piling in soft soil layer is often because the reaction is too small, the amount of compression is not sufficient to ignite the ignition, it needs to use the hook to lift a hammer from multiple impact, to start. The hammer seat of the diesel hammer is provided with a fuel injection pump, an oil tank, a cooling water tank and a pile cap. The movable gap between the plunger and the cylinder is sealed with an elastic plunger ring. Four, hydraulic hammer piling machine is a diesel belt start, to the oil pressure as the driving force, can be adjusted according to the formation of different soil pressure, in order to achieve the appropriate impact force for piling, is a new type of pile driver. Small and medium-sized hydraulic pile driver, commonly used in highway guardrail piling, highway guardrail construction. Similar pile driving equipment are: hydraulic pile driver, road pile driver, guardrail, pile driver, road drilling machine.

What is the starting current for a 55 kW pile driver? What's the big leakage switch, please?

250A circuit breaker startup selection step-down start cannot be launched directly, or may cause voltage drop greatly,

How many types of piling are there on the site?

According to the construction process and divided into cast-in-place pile and precast pileThe resistance of the soil to the pile is overcome by the impact of the pile hammer, so that the pile sinks to a predetermined depth or reaches the bearing layer. (of course, this is to explain "piling". There are several ways to make a precast pile to a predetermined depth or a bearing layer, such as static pressure, vibration, water, etc.)

My family is in the countryside, and now more than 100 meters behind the house in the pile is the kind of shock, our house is built in 99 years, has been very good. Since the piling, I have been shaking the door, the construction party every day for more than 8 hours, has been more than 10 days, and now I have a lot of cracks in the floor. What's the influence of our family, please? Are there any rules for investigating what should be done before piling?

In engineering piling, because of the huge impact force, it can produce shock wave, which will cause some damage to the surrounding building.
