pine wood pileIt is a commonly used construction wood. How is it constructed? Below we will introduce it to you.

The construction method of pine piles is as follows:

Depending on the method of piling, it can be divided into manual piling and mechanical piling. Common piling machinery and equipment include hand-cranked cranes and diesel pile drivers. Hydraulic excavators are also often used to drive pilings.

When using a hydraulic excavator to drive piles, two people need to hold the piles in place, turn the bucket back to buckle the wooden piles, and press the wooden piles into the roadbed to a certain depth and stability. Then let the pile helpers leave, and the excavator will push down the pine piles. Generally, one pile can be driven every 3-5 minutes, and the labor efficiency is high. In order to make the compaction more effective and improve the bearing capacity, the pile must be driven from the bottom 4 weeks to the inner hole. The layout of the pile is best with red plum blossoms. The distance between piles should not be less than 3 times the pile diameter.

After the piling is completed, the pile heads should be sawn flat according to the designed elevation so that the pile top foundation of each pile is maintained on the same plane. The sludge squeezed during piling should be excavated and a 20-750px thick graded sand and gravel mattress should be paved on the top of the pile. The cushion layer is compacted in all aspects, and then the base concrete is poured to ensure that part of the load is transmitted to the soil between the piles through the cushion layer and to adjust the sharing effect between the piles and the soil.

Setting the cushion layer under the foundation can reduce the pile-soil stress ratio, and by making full use of the function of the soil between piles, the value can be expanded and the stress at the bottom of the foundation can be reduced. By changing the thickness of the cushion layer, the sharing of the pile vertical load can be adjusted The thinner the cushion, the higher the load borne by the pile accounts for the total load, and vice versa.

The above is the construction method of pine piles that we have introduced to you. We hope it will be helpful to you. If you need to consult or order products, we welcome you to leave us a message or call us.
