Construction waste recycled aggregate composite carrier pile and preparation method thereof
The invention discloses a construction waste recycled aggregate composite carrier pile. The construction waste recycled aggregate composite carrier pile mainly comprises a rammed body, a pile body and a mattress layer, and is characterized in that the rammed body is formed by sorted construction waste on the outer layer and dry and hard recycled concrete on the inner layer; the pile body is composed of a pile casing above the rammed body, a steel reinforcement cage inside the pile casing and recycled concrete poured into the pile casing; the mattress layer is laid at the pile head position. A preparation method of the construction waste recycled aggregate composite carrier pile comprises the steps of smashing, screening, mixing, preparation of a pile moving machine in place, column-hammer tamping, pile casing follow-up hole formation, filler tamping, measurement of penetration of three drives, tamping and filling of the recycled concrete, placement of the steel reinforcement cage, filling of a finished pile, laying of the mattress layer and the like. The phenomenon that construction waste can not be used after old buildings are dismantled is solved, and the obtained composite carrier pile is good in expanded-base effect, high in single pile bearing capacity and small in deformation.
