Commonly used piling machines include hand winches and diesel pile drivers, and hydraulic excavators are also often used to drive wood piles.

When using a hydraulic excavator to drive piles, two people are required to hold the piles in place, turn the bucket upside down to hold down the wooden piles, and press the wooden piles into the foundation to a certain depth to stabilize themselves. Then let the pile helpers go away and the excavator will push down the pine piles. , generally one pile can be driven every 3-5 minutes, and the work efficiency is high.

In order to achieve a good squeezing effect and improve the bearing capacity of the foundation, piles must be driven from the 4th circumference of the base to the inner ring. The arrangement of piles is preferably in a plum blossom shape, and the distance between piles should not be less than 3 times the pile diameter.

Correct pine pile construction method:

After piling is completed, the pile heads should be sawn flat according to the designed elevation so that the top of each pile is basically kept at the same level. The silt squeezed out during piling should be excavated, and a 20-30cm thick graded sand and gravel mattress should be laid on the top of the pile. It is compacted, and then the bottom slab concrete is poured to ensure that the foundation transmits part of the load to the soil between the piles through the cushion layer and adjusts the sharing effect between the piles and the soil.

Setting up a cushion layer under the foundation can reduce the pile-soil stress ratio and give full play to the role of the soil between the piles, which can increase the value and reduce the stress concentration on the bottom surface of the foundation. By changing the thickness of the cushion layer, the sharing mattress of the vertical load of the piles can be adjusted. The thinner the cushion, the higher the load the piles bear as a percentage of the total load, and vice versa.

Advantages of pine piles

1. The color is natural, adhering to the natural nature of pine wood, and the texture is clear and beautiful.

2. The appearance is simple and elegant, with plump and smooth lines, showing good texture.

3. Strong applicability and durability.

4. The material selection, design and manufacture of pine furniture is of strong elasticity and breathability, good thermal conductivity and easy maintenance. Pine is a coniferous forest species.
