In addition to being used in piling construction, fir piles are often used as landscaping fir piles in various landscaping projects; because of the large crowns of large trees, relatively tall and small root systems, they cannot be fixed according to the trees themselves, and are easily damaged by wind. If the tree is blown down or tilted, even if the tree is shaken, the roots of the tree will easily shake, and the roots will rot after being exposed. Therefore, the tree needs to be supported after planting.

Usually, large trees are supported by fir stakes, depending on the size and height of the tree. In this project, large trees are usually supported by stakes in a symmetrical 3-corner or 4-corner shape, and the bottom is fixed by short stakes and supports. Therefore, it is not easy to slide in the wind.

One is the support of the pile body: the fir pile composite foundation replaces the low-modulus, low-strength soil of the same volume as the pile body. When an external load is applied, the foundation stress is redistributed according to the pile-soil stress ratio, and the stress gradually concentrates on the pile body. , the soil stress around the pile is reduced accordingly, and most of the load is borne by the fir pile.

Because the strength and deformation resistance of piles are better than those of soil, the bearing capacity and modulus of the composite foundation are also better than those of the original soil, thus reducing deformation and improving bearing capacity. When constructing fir piles, hammer driving is used , forcing the original soil at the pile hole position to be squeezed laterally, increasing the compaction of the soil layer within a certain range around the pile, and playing a compaction effect.

In the reinforcement process of the soil between the piles, the fir pile composite foundation makes the soil between the piles dense, improves the bearing capacity of the soil between the piles, and reduces the compressibility. The usage rate of fir piles is also relatively high now, as a river The use of piles is also relatively common.

The editor here reminds everyone that when purchasing fir piles, you must first ensure that there are no problems with their quality, otherwise it may directly affect subsequent use.
