The invention discloses a hinge type single-blade pile tip for a cast-in-place pile immersed tube. The hinge type single-blade pile tip comprises a pile tip tube body and two hinges, the hinges are divided into a left hinge and a right hinge, when the hinges are opened, discharging operation can be carried out, and when the hinges are closed, the hinges and blade feet on the two sides can be closed, a pile tube is closed, and pile sinking operation is carried out; when the pile tip is buried into soil, the two hinge flaps can be automatically closed under the counter-acting force of an underground soil body; in the lifting process after the pile tip is sunk in place, the two hinge flaps can automatically fall and rotate to the opening position under the action of self weight and concrete pressure, concrete or aggregate is poured into a hole-forming pile, and cast-in-place pile construction is completed. When the hinge type single-blade pile tip is used, the cast-in-place pile immersed tube can be welded into a whole, replacement is convenient, the positioning and guiding precision is high, the punching resistance is small, the pile forming quality is good, and pile breakage is not prone to happening; The hinge type single-blade pile tip is convenient to use, the working efficiency is improved, and the construction cost is reduced.
本发明公开了一种灌注桩沉管合页式单刀刃型桩尖，本桩尖由桩尖管身和两片合页组成，合页分为左、右侧合叶，打开时可进行放料作业，关闭时可与两边刃脚闭合，将桩管关闭，进行沉桩作业。桩尖在入土时，两片叶瓣可在地下土体反作用力下自动闭合；当桩尖沉桩到位后提升过程中，两片叶瓣可在自重和混凝土压力作用下，自动下落转动至打开位置，混凝土或骨料灌入成孔桩中，完成灌注柱施工，该型桩尖使用时可灌注桩沉管焊接成一体，更换方便，定位导向精度高、打孔阻力小，成桩质量好，不易断桩，使用方便，提高工效，降低了施工成本。
