Combined pier column, centering mechanism for pier column construction and pier column construction method
The invention discloses a combined pier column, a centering mechanism for pier column construction and a pier column construction method, and belongs to the technical field of bridge engineering. Comprising a UHPC pipe, *-shaped steel and waste fiber recycled concrete, the UHPC pipe serves as a permanent mold to be arranged on the outer layer, the *-shaped steel is arranged in the UHPC pipe, the *-shaped steel and the UHPC pipe are arranged in a concentric circle mode, and the waste fiber recycled concrete is poured between the UHPC pipe and the *-shaped steel in a layered mode to form a recycled concrete core. The UHPC pipe, the recycled concrete core and the *-shaped steel are connected into a whole; the UHPC pipe comprises ordinary Portland cement, a mineral admixture, quartz sand, quartz powder, steel fibers, a high-efficiency water reducing agent and water, and the mixing mass ratio of all the components is that the UHPC pipe comprises the ordinary Portland cement, the mineral admixture, the quartz sand, the quartz powder, the steel fibers, the high-efficiency water reducing agent and the water. According to the technical scheme, the compressive strength, tensile strength, toughness, durability and other performance of the combined pier column are improved, and the service life of the combined pier column is prolonged.
本发明公开了一种组合墩柱、墩柱施工用对心机构以及墩柱施工方法，属于桥梁工程技术领域。包括UHPC管、米字型钢、废弃纤维再生混凝土，所述UHPC管充当永久模具设置于外层，所述米字型钢设置于UHPC管的内部，且与UHPC管同心圆设置，所述废弃纤维再生混凝土分层浇注于UHPC管与米字型钢之间形成再生混凝土芯，所述UHPC管、再生混凝土芯和米字型钢连接成一体；所述UHPC管包括普通硅酸盐水泥、矿物掺和料、石英砂、石英粉、钢纤维、高效减水剂和水，各组分拌合质量比为：所述UHPC管包括普通硅酸盐水泥、矿物掺和料、石英砂、石英粉、钢纤维、高效减水剂和水。本技术方案用以提高组合墩柱的抗压强度、抗拉强度、韧性和耐久性等性能，延长组合墩柱的使用寿命。
