Today we will talk about the correctpine wood pileconstruction methods.

How to construct pine piles? According to different pile driving methods, they can be divided into manual pile driving and mechanical pile driving. Commonly used pile drivers include manual winches and diesel pile drivers. Zhenjiang fir piles and hydraulic excavators are also commonly used for pile driving. Hydraulic excavators are used for piling. When the excavator drives the piles, two people are required to hold the piles in place. Turn the bucket upside down to hold the piles, and press the piles into the foundation to a certain depth to stabilize themselves. The person holding the piles walks away, and the excavator pushes down the pine piles. Generally, It takes 3 to 5 minutes to drive a pine pile, which is more efficient. In order to achieve a good compaction effect and improve the bearing capacity of the foundation, the pile should be driven from 4 weeks inwards from the base. The placement of piles is preferably in a plum blossom shape, and the distance between piles should not be less than 3 times the pile diameter.

After piling, the pile heads should be sawn flat according to the planned 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 20-750px thick graded sand and gravel mattress should be laid on the top of the pile. Compact it, and then pour the base concrete to ensure that the foundation transfers part of the load to the soil between the piles through the cushion layer, and adjusts the pipe-dividing effect between piles and soil. Setting up a cushion layer under the foundation can reduce the pile-soil stress ratio. By giving full play to the effect of the soil between the piles, you can increase the value and reduce the stress concentration on the foundation surface. By changing the thickness of the mattress, the thinner the mattress for adjusting the vertical load of the pile, the greater the percentage of the load the pile bears in the total load. high, and vice versa. If there is no mattress layer, the effect of soil between piles cannot be exerted.
