Manhole well immersed pipe inlet and outlet device
The invention relates to the technical field of tunnels, in particular to a manhole well immersed pipe inlet and outlet device. The manhole well immersed pipe inlet and outlet device comprises a mounting base, a first manhole well pipe and a first sealing piece, wherein the mounting base is arranged at the position, provided with a manhole cover plate, of a pipe joint, the first manhole well pipe is arranged on the mounting base, the first manhole well pipe and the mounting base are coaxially arranged, and the upper end face of the first manhole well pipe extends out relative to the sea level; the first sealing piece is arranged between the mounting base and the first manhole well pipe and used for preventing seawater from flowing into the space between the first manhole well pipe and the mounting base. According to the manhole well immersed pipe inlet and outlet device, during mounting operation of sinking and butt joint of an immersed pipe, constructors can still enter and exit from the immersed pipe, and temporary ventilation can be achieved.
本发明涉及隧道技术领域，尤其涉及一种人孔井沉管的进出装置，其包括安装底座，设置在管节具有人孔盖板处；第一人孔井管，所述第一人孔井管设置在所述安装底座上，且与所述安装底座同轴线设置，所述第一人孔井管的上端面相对海平面伸出；第一密封件，所述第一密封件设置在所述安装底座与所述第一人孔井管之间，用于防止海水从所述第一人孔井管与所述安装底座之间流入。本发明在沉管沉放和对接的安装作业时，施工人员依然可以进出沉管，而且可以实现临时通风。
