Background
In the prior art, often adopt pine stake to carry out soft base and handle, pine stake composite foundation compares with other composite foundations, except that the material of stake is different, all other similar parts all have, its reinforcement mechanism: firstly, the supporting function of the pile body: the pine pile composite foundation replaces low-modulus and low-strength soil with the same volume as a pile body by the pine pile, and when bearing external load, the stress in the foundation is redistributed according to the pile-soil stress ratio. The stress is gradually concentrated to the pile body, the stress born by the soil body around the pile is correspondingly reduced, and most of the load is born by the pine pile. Because the strength and the deformation resistance of the pile are superior to those of the soil body, the bearing capacity and the modulus of the formed composite foundation are superior to those of the original soil body, and therefore the effects of reducing deformation and improving the bearing capacity are achieved. Secondly, compaction function: when the loose wood pile is constructed, the loose wood pile is hammered and driven, and the original soil body at the position of the pile hole is forced to be extruded laterally, so that the compactness of the soil layer in a certain range around the pile is improved, and the compaction effect is achieved. The compaction effect of the pine pile composite foundation on soil bodies among piles in construction enables the soil among the piles to be compact, so that the bearing capacity of the soil among the piles is improved, and the compressibility is reduced.
