Cast-in-place concrete pile adopting cement-soil mixing pile for pile bottom reinforcement and construction method
The invention provides a cast-in-place concrete pile adopting a cement-soil mixing pile for pile bottom reinforcement and a construction method. The cast-in-place concrete pile comprises the cast-in-place concrete pile and the cement-soil mixing pile below the pile end, and the cement-soil mixing pile is constructed through a pile hole of the cast-in-place concrete pile. The technical scheme provided by the invention has the beneficial effects that the bottom of the cast-in-place concrete pile is reinforced by adopting the cement-soil mixing pile, and the cement-soil mixing pile is constructed by utilizing the pile hole of the cast-in-place concrete pile, so that the construction cost is slightly increased, the soil strength of the pile end can be increased, the bearing capacity of the pile end is enhanced, and the deformation of the pile foundation is reduced; and the method has a wide application space in the field of geotechnical engineering.
本发明提供一种采用水泥土搅拌桩进行桩底加固的混凝土灌注桩及施工方法，包括混凝土灌注桩和桩端以下的水泥土搅拌桩，水泥土搅拌桩利用混凝土灌注桩的桩孔进行施工。本发明提供的技术方案带来的有益效果是：通过采用水泥土搅拌桩对混凝土灌注桩桩底进行加固，水泥土搅拌桩利用混凝土灌注桩的桩孔进行施工，在少量增加造价的同时可以增加桩端土强度，增强桩端承载力，减小桩基变形，在岩土工程领域的具有广泛应用空间。
