According to different foundation piling methods, they can be divided into manual service piles and mechanical equipment piles. Common pile drivers include manual cranes and diesel pile drivers. Hydraulic excavators are also commonly used for foundation piling. When using a hydraulic excavator for foundation piling, It takes two people to support the pile in time and tip the bucket back to buckle the fir pile.

The piles are driven into the foundation, which must be deep and self-stable. Then let the pile driver leave and use an excavator to press down the fir piles. Usually one pile is driven every 3-5 minutes. The work efficiency is high to improve the quality of the roadbed. To consolidate the effect and improve the bearing capacity, the piles must be released from near the base to the inner ring.

The pile position should be in the shape of a red plum blossom, and the pile distance should not be less than 3 times the pile diameter. After the piles are piled up, the pile heads should be sawn at an orderly design to keep the pile top base of each pile at the same level to eliminate cutting. The sludge squeezed during pile construction is used, and a 20-750px thick sand and gravel cushion is paved on the top of the pile. After compaction, it is poured into the road concrete to ensure that the roots migrate to the soil between the piles through the base cushion to adjust the piles. The effect of soil.

Set a base cushion at the root to reduce the pile-soil stress ratio and make full use of the soil between piles to increase the value and reduce the bottom edge stress at the root. After changing the base cushion thickness, adjust the pipe base cushion to be thinner. , to adjust the parallel line load of the pile, the higher the percentage of the pile load in the total load, and vice versa.

If you choose a fir pile wood board, you can smell the wood board. If there is a pungent smell, don't buy it. This may be the use of leftover glue from the wood board, which has high formaldehyde emissions and is harmful to the body. harm.

An important feature of pine board is the expansion and contraction of the wood. Under dry conditions, the wood will bend, shrink and crack; in a humid and cold environment, the wood will expand. Therefore, the wood will expand during production, processing or Punch holes before use to bring them close to the balanced moisture content consistent with the relative humidity of the air.
