Pile driving at construction sites mainly consists of precast piles, manually dug piles, driven tube piles, spiral drilling piles, and jet grouting piles. I'll explain each type in detail. Precast piles are driven, pressed, or vibrated into the soil at the factory or construction site using various materials and forms (such as wooden piles, concrete square piles, prestressed concrete pipe piles, steel piles, etc.). In China's construction sector, precast piles mainly include concrete and steel piles. Manually dug piles, also known as reinforced concrete manually dug piles and on-site cast-in-place piles, usually have a larger diameter, with the thinnest pile diameter greater than 800mm, capable of supporting smaller floors and larger pressures of the main structure. The widely used cast-in-place pile is one of the many types of pile foundations in civil engineering. It utilizes steel pipes (i.e., casing) that match the design dimensions of the pile. After covering the end with a pile tip and sinking it into the ground, the steel reinforcement cage is lowered into the casing, and concrete is poured while vibrating or hammering the casing out. The vibration during casing removal compacts the concrete, forming the required cast-in-place pile. This construction method is suitable for groundwater, quicksand, mud, etc., with cast-in-place piles directly opening holes at the design pile position, having a circular cross-section. After hole formation, the reinforcement cage is placed inside, and concrete is poured. It is used in urban construction. Spiral drilling cast-in-place piles use a spiral drilling machine to open holes at the pile position.

Jet grouting piles, also known as soil pile reinforcement, are a form of deep mixing method for foundation reinforcement. It's a method of mixing soft soil foundations with powdered solidifiers. Suitable for the reinforcement of saturated soft clay from various sources. In China, it is commonly used for the reinforcement of high moisture content silty soil, muddy soil, silt, and clayey soil.
