Unmanned caisson safe shipping system and shipping process

Abstract

The invention discloses an unmanned caisson safe transportation system and a transportation process. The transportation system includes a semi-submersible barge. The semi-submersible barge is provided with a cable for securing the caisson, and the cable is provided with a hook for connecting the caisson. Equipped with an automatic decoupling device, the semi-submersible barge is equipped with an automatic water-filling device that can inject water into the caisson. The automatic water-filling device includes a water supply mechanism, a water injection pipe connected to the water supply mechanism, and a limit unit that can adjust the position of the water outlet at the upper end of the water injection pipe. The water outlet is arranged above the caisson. After the caisson is placed on the semi-submersible barge and fixed, the shipping system and shipping process do not need to manually work on the top of the caisson, and can realize unmanned operation on the top of the caisson, making the caisson shipping process more safe, reliable, economical and efficient.

Description

technical field [0001] The invention relates to a caisson shipping technology, in particular to an unmanned caisson safe shipping system and a shipping process. Background technique [0002] The caisson is a bottomed box structure used in wharfs or breakwaters and other projects. The sinking or floating of the caisson can be controlled by adjusting the ballast water in the tank. After the onshore prefabrication of the caisson is completed, it is usually hauled to the construction site by semi-submersible barges, and then the workers on the caisson manually open the valve to open the water inlet at the bottom of the caisson to pressurize the caisson to meet the disembarkation conditions (the expected target is the ship's ballast load). After the caisson reaches its own floating stable state), it is towed to the sinking installation position by the tugboat for ballast sinking and installation. If the caisson itself is not stable enough after being pressurized and loaded on the...

AI Technical Summary

Problems solved by technology

At present, the caisson water injection method (adding ballast water) adopts the water inlet hole designed at the bottom of the caisson. During operation, the workers on the top of the caisson open the water inlet hole through the manual valve, and the water inlet speed is controlled by the worker through the valve. This caisson transportation process , There are usually 10-14 workers on the top of the caisson to install and remove the cables, water injection, water level observation and control, data recording and other operations, which consume a lot of manpower, and the caisson is floating at sea during the shipping process. Workers cannot evacuate the caisson in time, such as water leakage in the caisson, breakage of the towing cable, etc. In serious cases, the caisson will overturn and cause heavy casualties.
