fir logs

Chinese firlog pileSimply put, the material of the pile is wood. Generally speaking, the wood selected as the pile must be tough and durable. The lower end of the pile should be cut into a pyramid shape, and the length of the pile tip should be the diameter of the pile.12Times, it is convenient to drive wooden piles into the foundation. Wooden piles are easy to make, easy to store and transport, simple piling equipment, and low cost. The disadvantage of wooden piles is that they have low bearing capacity and will not have a long service life without anti-corrosion treatment.

Chinese firlog pileGenerally used forcomposite foundation, is a commonly usedpile foundation.The application scope of wooden piles is as follows: areas rich in wood; small projects and temporary projects, such as the foundation for erecting small bridges; the foundation for ancient cultural relics, such as the Longhua Tower in Shanghai, height40.40m, the foundation is silt soil, using350px450pxFor square piles, since the piles are filled with 3 layers of soil, the anti-corrosion effect is good; the pile tops should be driven below the groundwater level.0.5mFunction, the life of wooden piles is longer. Avoid the alternating wet and dry environment or above the ground. The wooden piles will rot quickly due to the action of microorganisms, and they should be corroded even in seawater.

Chinese firlog pileIt has the following characteristics: compared with bulk material piles, wooden piles have a certain degree of stiffness; compared with cement piles, the pile body strength and stiffness are relatively greater; compared with steel pipe piles, the pile body strength is lower; wooden piles The physical strength is close to that of concrete piles; it can be regarded as a special low-strength pile; its performance is close to that of rigid piles. Wooden piles can exert the lateral friction resistance of the pile throughout the length of the pile, and when the pile end falls on a good soil layer, it can By softly exerting pile end resistance, the wooden pile composite foundation can effectively form a cooperating body with the upper structure to improve the bearing capacity of the weak foundation. It has good deformation coordination and reduces uneven settlement of the foundation.
