The invention discloses a self-extending type construction method for a punching pile, and belongs to the technical field of punching cast-in-place piles. The self-extending type construction method for the punching pile comprises the following steps that preparation work is conducted; impact hole forming is conducted; a reinforcement cage and a guide pipe are placed; concrete is poured; and a pile casing mechanism comprises a cylinder body, vertical grooves are formed in the outer walls of the two sides of the cylinder body correspondingly, an extending grooving mechanism is arranged in the cylinder body and comprises an impact block, and a built-in groove is formed in the impact block. The pile casing mechanism and the extending grooving mechanism can be arranged to be matched with the construction method for construction, during impact hole forming, a plurality of extending holes communicating with a pile hole are formed in the two sides of the pile hole, thus during concrete pouring, concrete grout can automatically extend into the extending grooves, after concrete in the extending grooves is solidified, extending arms are formed, the extending arms can provide effective support, thus hole collapse and pile hole deflection are reduced, and the strength of the pile is improved.
本发明公开了一种冲孔桩自延伸式施工方法，属于冲孔灌注桩技术领域，一种冲孔桩自延伸式施工方法，包括以下步骤：准备工作；冲击成孔；安放钢筋笼及导管；灌注混凝土；护筒机构包括筒体，筒体两侧的外壁上均开设有竖槽，延伸开槽机构设置于筒体的内部，延伸开槽机构包括冲击块，冲击块的内部开设有内置槽。可以实现通过护筒机构和延伸开槽机构的设置，配合施工方法进行施工，在冲击成孔时，在桩孔两侧开设多个与桩孔连通的延伸孔，从而在浇注混凝土时，混凝土浆液可自动向延伸槽内延伸，延伸槽内的混凝土凝固后形成延伸臂，延伸臂可对能够有效的支撑，从而减少塌孔、桩孔偏斜的发生，提高了桩的强度。
