<Summary of caisson installation work>
First, a general construction method for installing the caisson 100 at the installation position G on the bottom of the sea or the like will be explained. FIG. 1 is a perspective view showing an example of a schematic configuration of a caisson construction support system 1 according to an embodiment. FIG. 2 is a side view showing an example of a schematic configuration of the caisson construction support system 1. As shown in FIG.

Conventionally, installation of the caisson 100 in water is performed, for example, in the following steps. The caisson 100 installed in the water is operated by draining water from the compartment 100A, floating it to the sea surface W, and connecting it to a winch installed on a work boat or existing structure using a rope, wire, etc. This allows it to be moored above the water surface at the installation location.

Primary injection is performed using the submersible pump 2 so that the water level difference between the compartments 100A is within about 1 m. The installation work vessel and the installation caisson 100 may sway due to deflection of the anchor rope, and the installation position G may shift, so the installation position G is adjusted again. The installation position adjustment is performed by operating the anchor rope of the installation work vessel or the winch 3 on the caisson 100. When installing the caissons, pay attention to waves and wake waves from passing ships. Further, the caisson 100 is placed on the bottom at a predetermined installation position G while being careful not to contact the existing structure due to unexpected movement of the caisson 100.

When the caisson 100 is installed at a predetermined position G, secondary water is injected to the top of the caisson 100 to bring the caisson 100 into a stable state. After that, a filling material with a high specific gravity is added to obtain a predetermined stability.

It is difficult to judge the stability of Caisson 100 in its floating state by looking at it, and extreme care must be taken as it tends to become unstable, especially in the early stages of water injection after towing.

In conventional installation work, a skilled engineer gave work instructions while constantly checking the dynamics of the installation caisson 100. Whether the oscillation of the installed caisson 100 was caused by periodic waves, a continuous change in attitude, or an unexpected cause was determined based on the experience of experienced engineers, and was reflected in the instructions. . Therefore, accurate and safe installation largely depends on the experience of experienced personnel.

The amount of water injected into each compartment 100A of the caisson 100 is adjusted by injecting water into the compartment 100A or draining the water in the compartment 100A into the water using the submersible pump 2. The caisson construction support system 1 includes a pump control panel 2A that controls the operation of a plurality of submersible pumps 2. The pump control panel 2A is installed on the installation caisson 100.

Further, the information creation unit 96 may create time series data of the center of gravity, center of buoyancy, and metacenter based on the calculated information on the center of gravity, center of buoyancy, and metacenter of the caisson 100. Note that the center of buoyancy refers to the center of buoyancy acting on the caisson 100 when the caisson 100 is floating on water, and can be calculated as the position of the center of gravity when the portion of the caisson 100 that is below the water surface is replaced with water. The center of buoyancy is a value that varies depending on the attitude of the caisson 100 and the volume of the portion below the water surface. The metacenter can be calculated as the midpoint between the center of gravity and the center of buoyancy.

Ru. Further, the route area 141 is, for example, defined as a space considerably larger than the size of the caisson 100 as it is farther from the installation position G, so that high positioning accuracy is not required; It is defined as , and is configured to obtain high positioning accuracy.

The elements included in each of the specific examples described above, their arrangement, conditions, shapes, etc. are not limited to those illustrated, and can be changed as appropriate. The elements included in each of the specific examples described above can be appropriately combined as long as no technical contradiction occurs.

In the embodiment described above, a configuration is illustrated in which the management room 10 (system control device 9, information display device 93) is installed on the installation caisson 100 that is being moved to install at the installation position G, but the management room 10 may be installed on a ship away from the installation caisson 100 or in an existing structure such as an existing caisson, and may be configured to remotely control the installation caisson 100. Generally, during caisson installation work, if workers operate various equipment on the caisson, there is a risk of being hit by a broken wire or falling into the sea with the equipment if the caisson topples. However, such risks can be avoided by separating the control room 10 from the installation caissons and performing remote control.
