Question:

What are the types of pile drivers? What are the characteristics of each?

What are the types of pile drivers? What are the characteristics of each?

Answer:

Pile foundation treatment has many ways, but according to the current market situation and the country's strict requirements for the foundation, many processes are not applicable, such as manual excavation, etc., the following are common and common process methods.According to backfill points: commonly used are lime soil pile, plain soil pile, cement pile, garbage pile and so on.According to the backfill compaction type: clamping rod hammer compaction, heavy hammer compaction
According to the hole forming process: the diesel hammer is immersed in the hole, the spiral drilling hole, and the Luoyang shovel holeIn accordance with the general classification of hole forming and compaction type: diesel hammer hole clamping hammer tamping hole; diesel hammer tamping; spiral drilling tamping (DDC); Luoyang shovel hole tamping and spiral drilling concrete pile (CFG). And what you say, pipe pile and fish, hammer, strong rammer are also belong to composite foundation. Among them, the pipe pile is divided into static pressure pile (suitable for static pressure machine into the ground) and diesel hammer pipe pile (diesel hammer directly into the ground).Several of the above are mainly to eliminate collapsibility and increase the composite bearing capacity, which belong to composite foundation. The main load of single pile is the cast-in-place concrete pile with rotary drilling holes.The above is the classification of the process, and how many layers are suitable for the construction.
This is not clearly defined. It mainly depends on the geological conditions and the superstructure. Who can tell you clearly that it is all Mongolia?.According to the above features you can see, generally divided into two categories, diesel hammer hole, drill hole, Luoyang shovel into the hole is used more, low cost, suitable for Northwest collapsible loess, the pile can eliminate the collapsibility of loess geology, increase the original basis composite bearing capacity. The pipe pile should be chosen according to the address condition, and the construction cost is high. According to the geological difference, sometimes the diesel hammer or drilling machine is needed to carry out the pre boring operation. Rotary drilling drill across the country for a variety of industries (work, the DAB, railways, highways, bridges, etc.), is the best way to operate a single pile.Specific choices are based on geological conditions and superstructure, and geological moisture content is also a key. I am engaged in the foundation construction, any questions contact at any time. Of course, there is a better engineering, ha ha, all kinds of machinery are available, are free equipment, reasonable price appropriate.
