More Information
Summary:The utility model discloses a construction structure with a guide hole and a gravel bed penetrated by a sunk pile, and belongs to construction engineering. The construction structure comprises upper-layer soil, the gravel bed, lower-layer soil and the guide hole, and is characterized in that the guide hole is perpendicular, the lower end of the guide hole is formed in a combination portion of the gravel bed and the lower-layer soil in a termination manner, and the guide hole is a hollow blind hole with the diameter which is slightly smaller than the diameter of a pile tube. Compared with the prior art, the construction structure with the guide hole and the gravel bed penetrated by the sunk pile has the advantages that the bottleneck that an existing sunk pile cannot penetrate a dense gravel bed due to uneven density of soil layers and complicated geological conditions and a pile sinking technology cannot be applied to constructing a foundation is broken through, and accordingly the construction structure has
