Pine piles are suitable for working under underground water. Pine piles should not be used in areas where the underground water level changes greatly or the underground water is highly corrosive.
Generally, when the thickness of soft soil is less than 5m, it is more suitable to use pine piles. In order to facilitate pile driving, the pile length should not exceed 4m. When making end-bearing piles, in order to ensure that the pile tip can enter the bearing layer, the upper part can be excavated to the depth of the foundation first. Then drive the pile. The pile material must be made of pine wood, because pine wood is rich in rosin, which can well prevent corrosion by open water and bacteria, and is also relatively cheap.
Pine wood piles are generally made of round and straight pine wood. Pine wood is rich in rosin, which can prevent it from being corroded by underground water and bacteria. It is suitable for working below the underground water level. However, it is highly corrosive to large changes in the underground water level or underground water. In areas with a certain nature, pine stakes should not be used.
Pine wood piles are mainly purchased in the local timber market and transported to the construction site warehouse by car. When purchasing wood piles, attention should be paid to the wood texture, and the pile length should be slightly longer than the designed pile length. The pile wood used must be of average material and must not be excessively bent. When the first and last ends of the wooden pile are connected to form a continuous line, the deviation level between the center of each section and the straight line must not exceed the relevant regulations; in addition, the pile body must not have holes, cracks or other defects that are sufficient to damage the strength.
Things to note when constructing pine piles
When lifting, loading, unloading, and stacking pine wood piles, the pile body must not be subject to impact or vibration to avoid damage to the pile body. When using wooden piles, they should be used in the order they are transported to the construction site, and the performance of the wooden piles should be checked at the same time. Whether it is in good condition. The foundation for storing wooden piles must be solid and flat, and there must be no subsidence to prevent the wooden piles from deforming.
Based on the theoretical experience of engineering construction on soft soil foundations, pine piles must carefully conduct engineering geological surveys and geotechnical experiments before designing soft soil foundations. Only by ascertaining the conditions of the soil layer and soil quality can the design and construction be carried out correctly; furthermore, , it is necessary to comprehensively consider the structure, construction and use of the foundation and foundation based on the characteristics of the soil layer and soil quality of the site, and rationally select the foundation solution through design comparison.
