Depending on the method of piling, it can be divided into manual piling and mechanical piling. Common piling machinery includes hand cranes and diesel pile drivers. Hydraulic excavators are also often used to drive pilings. Hydraulic excavators are also used to drive pilings. When the excavator is driving piles, two people are required to hold the piles in place, turn the bucket back to buckle the wooden piles, and press the wooden piles into the foundation to a certain depth and stability, and then let the pile helpers leave, and the excavator will push down the pine piles. Generally, each time A pile can be driven in 3-5 minutes, and the labor efficiency is high.

In order to make the compaction easier and increase the bearing capacity, the piling must be driven from the bottom 4 weeks to the inner ring. The layout of the piles is best with red plum blossoms, and the distance between piles should not be less than 3 times the pile diameter. After piling, it should be Saw the pile heads according to the designed elevation to keep the pile top foundation of each pile on the same plane. Remove the sludge squeezed during pile driving and pave a 20-30cm thick graded sand and gravel mattress on the top of the pile. The surface is compacted, and then the base concrete is poured to ensure that part of the load is transferred to the soil between the piles through the cushion layer and adjusts the sharing effect of the piles and soil. Setting the cushion layer under the foundation can reduce the pile-soil stress ratio , fully utilizing the function of the soil between piles can increase the value and reduce the stress on the basic bottom edge.

By changing the thickness of the cushion layer, the thinner the cushion layer that adjusts the vertical load of the piles, the higher the percentage of the load borne by the piles accounts for the total load, and vice versa. If there is no cushion layer, the soil between the piles cannot be fully utilized. effect.
