Embodiment

[0014] ① Use the vibrating immersed tube method to construct the granular pile composed of coarse aggregate, the coarse aggregate is sandstone (or crushed stone, sand, slag, pebbles, bricks and tiles).

[0015] ②In the center of the granular pile, use the vibrating sinking method to drive a high-bonding strength pile core, and the high-bonding strength pile core is a plain concrete pile (or reinforced pile, cement stone pile, cement fly ash gravel pile). That is, the outer periphery of the formed pile body is a granular pile, and the center of the granular pile is provided with a strong core composite pile with a high bonding strength pile core.

Abstract

The invention relates to a strength-core composite pile and a construction method. The outer periphery of the pile body is a granular pile, and a high-bonding strength pile core is arranged in the center of the granular pile. The construction method comprises the construction of the granular pile by the vibrating tube sinking method, and then driving the pile core with high bonding strength by the vibrating tube sinking method in the center of the granular pile. The invention can effectively reduce foundation deformation, enhance strength and rigidity of foundation soil, accelerate drainage and consolidation of soft soil, and prevent foundation soil from liquefying.

Description

Technical field: [0001] The invention relates to a pile formed in building construction and a construction method. Background technique: [0002] Due to the material and structure of the pile body, the existing pile foundation still has some unsatisfactory problems in effectively reducing the foundation deformation, enhancing the strength and stiffness of the foundation soil, accelerating the drainage and consolidation of soft soil, and preventing the liquefaction of the foundation soil. place, and the construction is complicated and the cost is high. Invention content: [0003] The object of the present invention is to provide a core composite pile and construction method with reasonable structure, which can effectively reduce foundation deformation, enhance the strength and rigidity of foundation soil, accelerate drainage and consolidation of soft soil, and prevent foundation soil liquefaction. [0004] Technical solution of the present invention is: [0005] A strong ...
