Building composite foundation pile top pre-piercing mattress layer
The invention discloses a building composite foundation pile top pre-piercing mattress layer, which comprises a mattress layer body, wherein the mattress layer body covers a position between the bottom surface of a foundation and the top of a pile body, a pre-piercing hole is formed in the bottom of the mattress layer body, the size of the pre-piercing hole is anastomotic with the top of the pile body. Meanwhile, the invention discloses a calculation mode of the pre-piercing hole. The building composite foundation pile top pre-pierce mattress layer has the beneficial effects that the composite foundation conventional pile top pad layer methods most adopt flat type, i.e., the thickness of the pile top and between-pile soil top surface pad layers can only be identical, according to the pre-piercing mattress layer provided by the invention, the depth of the pre-piercing hole can be flexibly regulated according to the load size, soil property conditions and pad layer material properties of concrete engineering in accordance with the pile soil stress ratio requirement required to be reached in the design, different pad layer thickness and pre-piercing depth can be adopted in a combined way in different positions of the same building, the composite foundation rigidity can be reasonably regulated through the difference control on the depth of the pre-piercing hole, and the difference sedimentation of the foundation is reduced.
