UHPC hollow column pier and construction method thereof
The invention discloses a UHPC hollow column pier which comprises a first column pier body, a second column pier body and a tie beam piece connected between the first column pier body and the second column pier body; the first column pier body and the second column pier body each comprise a first UHPC layer, a second structure layer and a third UHPC layer which are arranged from inside to outside,and the second structure layer comprises a plurality of stirrups and a plurality of longitudinal bars; the stirrups and the longitudinal bars are fixedly connected with each other to form a second structural layer; a hollow channel is reserved in the center of the first UHPC layer, and the tie beam piece is connected to the middle of the first column pier body and the middle of the second columnpier body to form an I-shaped double-column-pier structure. The invention aims to reduce pier materials in large-scale bridge engineering on the premise of meeting the construction requirements of earthquake resistance, strength, shearing resistance and bending resistance by using a new column pier structure. The invention further discloses a construction method of the UHPC hollow column pier, andthe construction method is used for guiding construction and manufacturing of the UHPC hollow column pier and improving the manufacturing efficiency and the success rate.
本发明公开了一种UHPC空心柱墩，包括第一柱墩、第二柱墩、连接在第一柱墩和第二柱墩之间的系梁件，所述第一柱墩、第二柱墩均包括自内向外设置的第一UHPC层、第二结构层、第三UHPC层，所述第二结构层包括多个箍筋和多个纵筋，所述箍筋和纵筋互相固定连接构成第二结构层；所述第一UHPC层中心位置预留有中空通道，系梁件连接于第一柱墩和第二柱墩的中部以形成工字型双柱墩结构。本发明旨在以新的柱墩结构，在满足抗震、强度、抗剪、抗弯的施工需求的前提下，减少大型桥梁工程中的桥墩用料。本发明还公开了一种UHPC空心柱墩的施工方法，用以指导UHPC空心柱墩的施工制造，提高制造效率和成功率。
