According to different piling methods, it can be divided into artificial pine piling and mechanical piling. Commonly used piling machines include manual winches and diesel piling machines. Hydraulic excavators are also commonly used for piling. When using a hydraulic excavator to drive piles, two people are required to fix the piles in place. Turn the bucket upside down to fix the pile, press the pile into the foundation to a certain depth and stabilize it on its own, then let the pile support device detach, and the excavator will loosen the pile. Generally, piling can be driven once every 35 minutes, and the operation efficiency is high. In order to achieve excellent results For compaction to increase the bearing capacity of the foundation, piles must be driven from around the foundation to the inner ring. The piles should be arranged in a plum blossom shape, and the distance between piles should not be less than 3 times the pile diameter.

After piling is completed, the pile heads should be sawed flat according to the planned elevation so that the tops of the piles are basically at the same level. The silt squeezed out during piling should be removed, and a 20-30cm thick sand and gravel cushion should be placed on the top of the piles. After compaction, the floor concrete should be poured. , ensure that the foundation transfers part of the load to the soil between piles through the cushion, and adjusts the pile-soil separation effect. Setting a cushion under the roots can reduce the pile-soil stress ratio, give full play to the role of the soil between piles, and reduce the stress on the bottom surface of the roots. Set. After changing the thickness of the cushion, the thinner the cushion responsible for regulating the vertical load of the piles, the higher the percentage of the pile load in the total load, and vice versa. If there is no cushion, the effect of the soil between the piles will not work.

In general construction, it is necessary to lay a good foundation, and pine piles are generally used as solid road foundations. Among them, due to the corrosion resistance of pine piles, the pine piles themselves metabolize turpentine, which can be used as a chemical to kill insects. How can we better prevent flying insects? moth?

Anti-corrosion of pine piles: Although they are effective in preventing and controlling woodworm, all chemicals have toxic and side effects. Therefore, safety protection measures must be taken during the operation, and players must be taken care of after the actual operation. There are many chemical methods .There are 5 common steaming methods, steaming method, sizing method, pre-impregnation method and pressure loading method.

After the above explanation, we have a certain understanding of the prevention and control methods of pine pile borers. In fact, the insect prevention methods of many wooden furniture are the same, but because people put furniture in the room, you often come into contact with people, so The chemical methods written above can easily cause damage to furniture. Physical methods are generally chosen. However, pine stakes are used for the foundation, so both methods can be used.
