Abstract

The invention relates to the construction and manufacturing field of seabed immersed tunnels, in particular to a dock gate caisson structure capable of achieving two-way water stop. The dock gate caisson structure comprises a dock gate caisson, a dock gate base plate, dock blocks, first preformed grooves, second preformed grooves, a water stop steel plate, a small steel gate and water stop belts. The dock gate caisson is arranged between the dock blocks and located on the dock gate base plate. The matched faces between the two sides of the dock gate caisson and the dock blocks are provided with the corresponding first preformed grooves respectively, the dry dock side of the dock gate caisson is provided with a dock opening, the portion, at the dock opening, of the dock gate base plate is provided with the second preformed grooves, the water stop steel plate is matched with the two corresponding first preformed grooves, the small steel gate is matched with the second preformed grooves, and the small steel gate and the dock gate base plate are provided with the water stop belts respectively. The dock gate caisson structure is simple, easy to operate, good in sealing and water stop effect, and capable of achieving the two-way water stop purpose that water inflowing is prevented during dry dock construction and water outflowing is prevented during dry dock water storage on the same site.

Description

technical field [0001] The invention relates to the field of construction and manufacture of submarine immersed tube tunnels, in particular to a two-way watertight dock door caisson structure. Background technique [0002] With the development of large-scale immersed tube tunnel projects, after the prefabrication of immersed tubes is completed, water must be stored in shallow docks, and the pipe joints must be floated to deep docks for secondary outfitting and undocking for installation. Due to the operation of dry dock construction and water storage in the dock during the construction process, the dock door is required to have good sealing and water-proof performance. During the construction of the same site that requires dry dock construction and water storage in the dock, it will affect the smooth progress of the construction. [0003] Therefore, aiming at the problem that the dock door cannot perform two-way water sealing, the present invention provides a two-way water ...
