(1) Pine wood piles are made of "logs" and do not need to be sawed into other shapes, especially if they cannot be sawed in half to form a semicircular shape. The semicircular pile will bend significantly after being cut quickly, resulting in loss of effect.

(2) Do not promote "pine wood piles" as "cedar wood piles" or other piles. Most common wood is resistant to water and will quickly turn black, deform and rot in water. This is especially true for pine wood. Do not open the application again.

(3) The design method of pine pile composite foundation is similar to that of general composite foundation, except that the pile center distance is usually not large.

(4) It is necessary to fully consider the pile-driving impact force that pine piles can withstand. The pile-driving impact performance will be within 300kg.m; if it gets larger, even logs with a tail diameter of 16cm will not be able to bear it.

(5) The horizontal resistance of the subgrade soil in sludge areas is not great, and the overall horizontal deviation is easy to occur above the pine pile group, causing damage to the road equipment; therefore, even if the horizontal load requirements for earthquake disasters are not considered, most of them are on pine piles. A stone layer is paved between the piles to increase the horizontal bending stiffness of the pile group as much as possible. The stone layer can only be paved manually, and the pine piles should be squeezed one by one as tightly as possible.

The above is the basic information about the construction plan and common problems of pine pile engineering for everyone. Have you mastered the professional knowledge in this area? I believe that you can only read this article carefully. When you encounter the application of pine pile engineering construction, start now Just know how to do it. I hope this article will be of help to everyone.
