The invention discloses an annular hydraulic cylinder and a method for jacking a bridge and a building through the annular hydraulic cylinder. The hydraulic cylinder and the method are used for solving the problems that when supporting columns of the bridge and the building are supported in a multi-point mode, operation is complex, and data accuracy is not high. The annular hydraulic cylinder is used for supporting columns in the bridge and building construction process and comprises an annular cylinder body, and an annular piston, wherein the annular piston is arranged between an inner ring and an outer ring of the annular cylinder body, moves relative to the annular cylinder body and is used for supporting the columns. A closed space is formed between the annular cylinder body and the annular piston and is used for storing hydraulic liquid. The annular cylinder body and the annular piston are made of steel materials. The annular piston moves relative to the annular cylinder body and has a first matching state and a second matching state. In the first matching state, the hydraulic liquid is injected into the closed space and pushes the annular piston to ascend. In the second matching state, the closed space drains the hydraulic liquid, and the annular piston descends along with the hydraulic liquid. By the adoption of integral support design, the operation steps are simplified, and the data accuracy is improved.

    本申请公开一种环形液压缸及用环形液压缸顶升桥梁及建筑的方法,用以解决多点支撑桥梁及建筑的支柱时操作复杂及数据准确性不高的问题。其中,一种环形液压缸,用于桥梁及建筑施工过程中支撑柱子,包括:环形缸体;设置于环形缸体的内环与外环之间、相对环形缸体运动的环形活塞,用于支撑柱子;环形缸体与环形活塞之间组成密闭空间,用于存储液压液体;环形缸体、环形活塞采用钢材料制得;环形活塞相对于环形缸体运动,具有第一配合状态和第二配合状态;第一配合状态下,密闭空间注入液压液体,液压液体推动环形活塞上升;第二配合状态下,密闭空间排出液压液体,环形活塞跟随液压液体下降。采用整体支撑设计,简化了操作步骤,提高了数据准确性。
