Measuring and setting out → excavating and filling the working face → setting out the pile position → loosening the pile → sawing the pile head → burying rubble and constructing C 10 concrete cushion → constructing the bearing platform.

The stakes are mainly purchased in the local timber market and transported to the warehouse by car. Pay attention to wood grain when buying wooden stakes, and the pile length should be slightly longer than the design pile length. The material of pile wood used must be uniform, and there must be no excessive bending. When both ends of the stake are connected in a straight line, the deviation between the center of each section and the straight line shall not exceed the relevant provisions; In addition, there shall be no holes, cracks or other defects that may damage the strength.

Matters needing attention in using pine stakes

1. pine stakes are made of logs. Don't cut them into other shapes, especially cut them in half into a semicircle. Semicircular stakes will soon bend strongly and lose their effectiveness.

2. Don't extend pine stakes to Chinese fir stakes or other stakes. Most common wood is hydrophobic, and will soon turn black, deform and rot when exposed to water, especially Chinese fir, which must not be used.

3. The design method of loose wood pile composite foundation is similar to that of common composite foundation, but the pile spacing is often very small.
