Steel-concrete composite pile as well as preparation method and application of steel-concrete composite pile
The invention provides a steel-concrete composite pile and a preparation method and application of the steel-concrete composite pile, the steel-concrete composite pile comprises a steel pipe pile located on water and a concrete large pipe pile located underwater, the steel pipe pile and the concrete large pipe pile are connected through a connecting section, and a steel pile shoe is arranged on the side, away from the steel pipe pile, of the large pipe pile; flanges used for connecting the steel pipe pile and the concrete large pipe pile are arranged on the two sides of the connecting section respectively, the flanges close to the concrete large pipe pile act on the concrete large pipe pile at the same time to generate prestress, and the concrete large pipe pile comprises a plurality of steel pipe piles which are made of C60 or C70 dry hard concrete through a centrifugal vibration rolling composite technology. And the pipe joint is formed by pouring a spiral bar and a longitudinal steel bar matched with the steel bar hole. According to the steel-concrete composite pile, the advantages of low manufacturing cost of a concrete pipe pile and good bending resistance of a steel pipe pile are combined, and the purpose of reducing cost is achieved on the premise that the engineering quality requirement is met.
本发明提供了钢混复合桩、钢混复合桩的制备方法及其应用，所述钢混复合桩包括位于水上的钢管桩以及位于水下的混凝土大管桩，所述钢管桩和混凝土大管桩之间通过连接段连接，所述大管桩远离钢管桩的一侧设有钢桩靴；所述连接段两侧分别设置有用于连接钢管桩和混凝土大管桩的法兰，且靠近混凝土大管桩处的法兰，同时作用于所述混凝土大管桩，产生预应力，所述混凝土大管桩包括若干个采用C60或C70干硬性混凝土通过离心振动辊压复合工艺，配合钢筋孔螺旋筋以及纵向钢筋浇筑而成的管节。本发明中的钢混复合桩结合了混凝土管桩造价低和钢管桩抗弯性能好的优点，在满足工程质量要求的前提下又达到了降低成本的目的。
