Problems solved by technology

However, the problem existing in the prior art is that during the sinking installation process of the immersed tube, construction personnel cannot enter and exit the immersed tube through the manhole door 400.
[0003] In view of this, it is urgent to provide a vertical temporary channel for entering and exiting the immersed tube and an installation method for the channel, so as to solve the problem that construction personnel cannot normally enter and exit the pipe joint during the installation process of the immersed tube in the prior art

Abstract

The invention relates to the field of floating transport construction of a submarine immersed tube tunnel, and provides a vertical temporary passage for entering and exiting an immersed tube and a construction method of the vertical temporary passage. The vertical temporary passage has the advantages that the temporary passage is arranged under a manhole well, and the passing at the exterior and in a tube joint can be realized by the temporary passage in a tube joint sinking installation process of the immersed tube, so as to facilitate the subsequent construction; the temporary passage is stable and durable; the construction and detachment are simple, convenient and rapid, and repeated detachment and installation for multiple times are realized; after the temporary passage is detached, since the size is small, the transportation and storage are convenient.

Description

technical field [0001] The invention relates to the field of floating construction of subsea immersed tube tunnels, in particular to a vertical temporary channel for entering and exiting immersed tubes and an installation method for the channel. Background technique [0002] See figure 1 , the pipe section of the immersed tube tunnel includes a concrete pipe gallery 200, an end steel shell 100 outside the concrete pipe gallery 200, and a steel sealing door 300 on the end face of the joint. Concrete pipe gallery 200 generally includes a middle corridor and two side corridors, and all equipment for installation of immersed pipes is generally stored in the lower layer of the middle corridor; while the two side corridors are mainly used for driving. The steel seal door 300 is fixed on the embedded parts by welding and bolts. It takes a long time to dismantle the pipe joints after the butt joint is completed. Therefore, it is necessary to open a manhole door 400 on the steel sea...
