Construction method of deep foundation pit angle supporting pile column component
The invention discloses a construction method of a deep foundation pit angle supporting pile column component. The construction method comprises the steps that construction preparation is conducted; a stand column pile hole is constructed; a square steel pipe is positioned and connected with a reinforcement cage; the square steel pipe and the reinforcement cage are hoisted and lowered; the middle section of the square steel is hoisted; the top section of the square steel is hoisted; concrete is poured; the top of the square steel pipe is sealed. C35 self-compacting concrete continues to be poured into the pouring hole above the square steel pipe, due to the fact that the middle of the square steel pipe is hollow, the reinforcement cage is located on the outer side of the square steel pipe, a large amount of C35 self-compacting concrete forms gravity pressure in the hollow middle of the square steel pipe, and the C35 self-compacting concrete is forced to upwell from the bottom between a concrete protection wall and the square steel pipe, the problem that the reinforcement cage forms a blocking concrete in the square steel pipe and is difficult to rapidly upwelling from the position between the stand column pile hole and the square steel pipe is solved, and then the upwelling C35 self-compacting concrete wraps the reinforcement cage till concrete thick slurry returns to a square steel pipe pouring hole, the C35 self-compacting concrete wraps the outer side of the square steel pipe after being solidified, and the problem that the square steel pipe is prone to being oxidized and damaged is solved.
本发明公开了一种深基坑角支撑桩柱构件的施工方法，包括：施工准备；立柱桩孔施工；方钢管与钢筋笼定位连接；方钢管与钢筋笼吊装下放；吊装方钢中段；吊装方钢中段顶段；混凝土浇筑；方钢管顶部封口。向方钢管上方的浇筑孔继续浇筑C35自密实混凝土，由于方钢管中部为空心，钢筋笼位于方钢管外侧，大量的C35自密实混凝土在方钢管的空心中部形成重力压强，迫使C35自密实混凝土从混凝土护壁与方钢管之间底部向上涌，解决了钢筋笼在方钢管内形成阻挡混泥土很难快速从立柱桩孔与方钢管之间上涌的问题，而后上涌的C35自密实混凝土包裹钢筋笼至方钢管浇筑孔返混凝土浓浆为止，C35自密实混凝土凝固后包裹方钢管外侧解决了方钢管容易氧化损坏的问题。
