Process for mounting manhole well on steel shell of immersed tube tunnel
The invention relates to the technical field of manhole well mounting, and discloses a process for mounting a manhole well on a steel shell of an immersed tunnel. The mounting process comprises the following steps that S1, a steel cylinder is placed in a mounting hole, and the steel cylinder is welded to an inner panel; S2, an exhaust pipe is installed on a lower sealing plate to form a first assembly, and a first annular steel liner is installed on an upper sealing plate to form a second assembly; S3, after a steel shell immersed tube is immersed and positioned, a worker is made to be located in the steel cylinder, and the second assembly is placed at the top end of the steel cylinder and welded to an outer panel in an overhead manner; S4, a second annular steel liner is installed on the lower sealing plate, and the worker places the first assembly at the bottom end of the steel cylinder in the steel shell immersed tube and welds the first assembly to the inner panel in an overhead manner; and S5, concrete pouring is conducted in the steel cylinder, air in the steel cylinder is exhausted out of the steel cylinder through an exhaust pipe and an exhaust hole, and then a pouring hole and the exhaust hole are blocked. The process has the advantages of being high in mounting efficiency and small in mounting difficulty.
本发明涉及人孔井安装技术领域，公开了一种沉管隧道钢壳上人孔井安装工艺。安装工艺包括以下步骤：S1：将钢圆筒放置在安装孔内，并将钢圆筒焊接至内面板；S2：将排气管安装在下封板上以形成第一组件；并将第一环形钢衬垫安装在上封板上以形成第二组件；S3：将钢壳沉管沉放并定位后，使工作人员位于钢圆筒内，将第二组件放置在钢圆筒的顶端并仰焊至外面板上；S4：将第二环形钢衬垫安装在下封板上，使工作人员在钢壳沉管内，将第一组件放置在钢圆筒的底端并仰焊至内面板上；S5：对钢圆筒内进行混凝土浇筑，且钢圆筒内的空气通过排气管及排气孔排至钢圆筒外；再对浇筑孔及排气孔封堵。有益效果：使人孔井的安装效率高及安装难度小。
