Generally, the thickness of soft soil is less than5mIt is more suitable to usepine wood pileIn order to facilitate pile driving, the pile length should not exceed4m.When making end-bearing piles, in order to ensure that the tip of the pile can enter the bearing layer, the upper part can be excavated to the burial depth of the foundation before driving the pile. The material of the pile must be pine, because pine is rich in rosin, which can well It prevents corrosion by groundwater and bacteria and is relatively cheap.

  pine wood pileSuitable for working below groundwater. It is not suitable for use in areas where the groundwater level changes greatly or the groundwater is highly corrosive.pine wood pile.

  Practice has proved that when short wooden piles are used to deal with weak foundations, they have the advantages of convenient construction and obvious economic benefits. They can avoid a large amount of earth excavation. Therefore, they are used in areas with abundant pine wood resources.pine wood pileIt is economically and technically feasible to deal with weak foundations, and it can be regarded as an effective means to deal with weak foundations.
