Fabricated bridge structure in tunnel and method thereof
The invention discloses a fabricated bridge structure in a tunnel and a method thereof, and belongs to the technical field of bridges. Comprising a bearing platform, stand columns and steel bar connecting mechanisms. The bearing platform comprises a plurality of embedded steel bars and a plurality of screws, the embedded steel bars are annularly distributed, and the protruding ends of the embedded steel bars are fixedly connected with the screws; the stand column comprises a plurality of main reinforcements and a plurality of sleeves, the main reinforcements are annularly distributed, and the sleeves are arranged outside the main reinforcements in a sleeving mode. The reinforcing steel bar connecting mechanism is arranged in the sleeve and comprises a plurality of internal thread sleeves, the internal thread sleeves are rotationally connected with the main reinforcing steel bars, the internal thread sleeves slide in the axis direction of the main reinforcing steel bars, the internal thread sleeves are in threaded connection with the screw rods, the lower ends of the main reinforcing steel bars and the upper ends of the embedded reinforcing steel bars can be fixed, and the overall strength of the spliced bridge is improved.
本申请公开了一种隧道内装配式桥梁结构及其方法，属于桥梁技术领域。包括承台和立柱以及钢筋连接机构；承台包括有若干预埋钢筋和若干螺杆，预埋钢筋环形分布，预埋钢筋的凸出端固定连接有螺杆；立柱包括有若干主筋和若干套筒，主筋环形分布，套筒套设在主筋外部；钢筋连接机构设置在套筒内，钢筋连接机构包括有若干内螺纹套管，内螺纹套管与主筋转动连接，内螺纹套管沿着主筋轴线方向滑动，内螺纹套管与螺杆螺纹连接，可将主筋的下端和预埋钢筋的上端完成固定，提高了桥梁拼接后整体的强度。
