The invention provides a grouting squeezing and expanding steel pipe concrete stand column pile and a construction method thereof. The grouting squeezing and expanding steel pipe concrete stand column pile comprises a steel pipe concrete pile section and a steel pipe concrete stand column section. The steel pipe concrete pile section is constructed by adopting drilling implantation and grouting squeezing and expanding processes, and a pile side area is formed outside the peripheral wall of the steel pipe concrete pile section; when the steel pipe is implanted into the drill hole, slurry is attached to the outside to replace the grouting pipe and used for grouting the pile side area. The steel pipe concrete pile section comprises a grouting squeezing and expanding device, and the grouting squeezing and expanding device is located at the bottom of the steel pipe concrete pile section. According to the configuration, the side resistance of the concrete-filled steel tube pile section is improved by replacing pile side slurry with cement slurry and performing grouting extrusion and expansion; meanwhile, a steel reinforcement cage is replaced by the steel pipes, so that construction procedures are reduced, materials are saved, and the construction cost is reduced; in addition, concrete pouring and pile side grouting can be conducted at the same time, and the construction efficiency is improved.
本发明提供一种注浆挤扩钢管混凝土立柱桩及其施工方法，所述注浆挤扩钢管混凝土立柱桩包括钢管混凝土桩段和钢管混凝土立柱段；所述钢管混凝土桩段采用钻孔植入和注浆挤扩工艺施工，所述钢管混凝土桩段的外周壁之外形成桩侧区；钢管植入钻孔时外附泥浆置换注浆管，用于向所述桩侧区注浆。所述钢管混凝土桩段包括注浆挤扩装置，所述注浆挤扩装置位于所述钢管混凝土桩段的底部。如此配置，通过水泥浆置换桩侧泥浆和注浆挤扩，使得钢管混凝土桩段的侧阻力得到提高；同时，利用钢管代替了钢筋笼，减少了施工工序，节省了材料，降低了工程造价；此外，混凝土灌注与桩侧注浆能够同时进行，提高了施工效率。
