Open-cell caisson structure and construction method

Abstract

The present invention relates to a caisson structure and a construction method therefor which introduces, in a novel way, a concept of an open cell and an inter-cell to a caisson, such that when compared to a conventional individual caisson structure, there is little difference in construction method while manufacturing costs are reduced by reducing the number of walls, and flexibility allowing each caisson to individually respond to the differential settlement of the ground is ensured, while adjacent caissons are interlocked by a flexible riprap.

Description

technical field [0001] The present invention relates to a caisson structure and a construction method. More specifically, it relates to the concept of introducing an open cell and a closed cell into a caisson, whereby the number of walls is reduced compared to a conventional individual caisson structure, thereby saving manufacturing costs. There is almost no difference in construction method and cost. Adjacent caissons are connected to each other through flexible sandstone. Each caisson has a flexible caisson structure and its construction method that can individually correspond to different settlements of the ground. Background technique [0002] Generally, caissons are structures that must be used when building harbors. For example, it is suitable for important facilities in harbors such as gravity walls and breakwaters. [0003] Recently, due to the global warming effect, the sea level has risen, and as a result, abnormal waves with higher wave heights than the design wa...

Problems solved by technology

However, the construction itself of this construction method is difficult. After the construction, the multiple caissons are fully integrated by pouring concrete in the space where the two caissons face each other. The caissons in the position cannot be freely settled together, and the stress generated by the inability to settle due to the super-high load subsidence is concentrated in a specific part, and the possibility of the caisson being destroyed is extremely high.

[0009] And, even after the various settlements of the ground have all proceeded, as described above, the external force based on the wave continues to act for 30 to 50 years in the state in which the settlement is constructed after the caisson is constructed, and during the above period, the adjacent The connection parts between the caissons are not flexible. After a moment, if the connection part becomes a rigid body, the one caisson where the horizontal force of the wave is concentrated pushes backwards and sinks to transfer the load to both sides of the connection. At this time, the load is concentrated on A location where a joint acts as a rigid body, resulting in a subsidence being broken

[0010] On the other hand, after the caisson is installed on the seabed, before the filling material is filled into the caisson, the subsidence cannot exert the design load, and it is difficult to withstand waves
