Reinforcement for cast in place top pile monolithically poured top pile foundation using the same and construction method of top pile foundation
The present invention relates to a reinforcement member for a cast-in-place top pile, an integrated top pile foundation using the same, and a construction method of the integrated top pile foundation. The reinforcement member for a cast-in-place top pile is configured such that a top pile structure having a wide upper portion and a narrow lower portion is formed in an aggregate compaction layer at the spot with a filler such as cast-in-place concrete, and the plurality of top piles are integrated into one structure, thereby being able to easily and significantly improve the soil bearing capacity of the foundation of the structure. The reinforcement member for a cast-in-place top pile of the present invention is arranged mutually at regular intervals in the aggregate compaction layer to construct the top piles to be placed in the aggregate compaction layer at the spot. The reinforcement member has a corn shape with a wide upper portion and a narrow lower portion, wherein the upper portion is opened. The reinforcement member comprises a top reinforcing member, in which a plurality of rows of vertical members and horizontal members are alternately disposed in a net shape, such that a part of paste of the cast-in-place filler, which fills the inside of the reinforcement, is discharged to the outside and is diffused and injected into an outer side of the aggregate compaction layer so as to form an outer reinforced portion. The total area of net eyes of the top reinforcing member is equal to or greater than 40% of the total area of the top reinforcing member.
본 발명은 골재 다짐층에 상광하협 형상의 팽이말뚝 구조체를 현장에서 현장 타설 콘크리트 등의 채움재로 바로 형성하는 한편 복수의 팽이말뚝을 하나의 구조체로 일체화할 수 있어 간편하게 구조물 기초의 지내력을 크게 향상시킬 수 있는 현장 타설 팽이말뚝용 보강재, 이를 이용한 일체형 팽이말뚝 기초 및 일체형 팽이말뚝 기초의 시공방법에 대한 것이다. 본 발명 현장 타설 팽이말뚝용 보강재는 골재다짐층에 현장 타설되는 팽이말뚝을 시공하기 위해 상기 골재다짐층에 상호 일정 간격 이격되도록 배치되는 것으로, 상기 보강재는 상부가 개방된 상광하협의 콘 형상이고, 내부에 채워지는 현장 타설 채움재의 페이스트 일부가 외부로 유출되어 외측의 골재다짐층에 확산 주입되면서 외측보강부를 이룰 수 있도록 복수 열의 가로재와 세로재가 서로 교차하여 망형으로 형성되는 팽이보강체를 포함하여 구성되되, 상기 팽이보강체의 망눈의 전체 면적은 팽이보강체 전체 면적의 40% 이상인 것을 특징으로 한다.
