Rock stratum ultra-deep steel pipe column and uplift pile combined construction technology
The invention discloses a rock stratum ultra-deep steel pipe column and uplift pile combined construction technology. The rock stratum ultra-deep steel pipe column and uplift pile combined construction technology comprises the following steps of S1, performing underground space breaking and backfilling; S2, surveying and setting out, and positioning an orifice; S3, drilling a guide hole, and burying a pile casing; S4, drilling a formed hole; S5, hoisting a reinforcement cage and a steel pipe column: prefabricating the steel pipe column and the reinforcement cage, arranging a plurality of studs on the outer wall of one end of the steel pipe column along the circumferential direction, extending the steel pipe column into the reinforcement cage by a certain distance, connecting the part of the steel pipe column extending into the reinforcement cage with the reinforcement cage through a plurality of connecting pieces to manufacture a connector of the reinforcement cage and the steel pipe column, and then putting down the connecting body into the formed hole; S6, installing a guide pipe; S7, performing concrete pouring; and S8, performing orifice backfilling. The construction steps are simple, the construction efficiency is improved, the connection strength of the connector of the steel pipe column and the reinforcement cage is improved, the reliability is high, and potential safety hazards are reduced.
本发明公开了一种岩石地层超深钢管柱与抗拔桩联合施工工艺，包括以下步骤：S1、地下空间破除，回填；S2、测量放线，孔口定位；S3、钻引孔，护筒掩埋；S4、钻成孔；S5、钢筋笼联合钢管柱吊装：预制钢管柱和钢筋笼，在钢管柱一端外壁沿圆周方向设置若干栓钉，将钢管柱伸入钢筋笼的内部一定距离，并将钢管柱伸入钢筋笼内部的部分与钢筋笼通过若干连接件连接，制作成钢筋笼和钢管柱的联接体，再将联接体下放成孔中；S6、导管安装；S7、混凝土浇筑；S8、孔口回填。本发明施工步骤简单，提高施工效率，而且提高钢管柱与钢筋笼的联接体连接强度，可靠性高，降低安全隐患。
