Description

Friction resistance increasing type caisson manufacturing system and manufacturing method {CAISSON AND METHOD FOR MANUFACTURING OF CAISSON WITH FRICTION INCREASED STRUCTURE}

The present invention relates to a system and method for manufacturing a new type of caisson with increased frictional resistance. More specifically, the uneven shape on the bottom of the base slab of the caisson is not formed only on the side of the moving passage, but extends to the entire flat portion of the first step to form the uneven portion on the entire bottom of the base slab, so the friction between the caisson and the rubble mound The present invention relates to a frictional resistance-enhancing caisson manufacturing system and manufacturing method that can improve the stability of the caisson structure by increasing the resistance to the horizontal load of waves or earth pressure by increasing the caisson.

In general, caissons are thousands of tons of weight built from reinforced concrete structures. For this reason, it is very dangerous and requires a high level of technology to transfer the caisson step by step within the production site (Casting Bed) to manufacture the caisson and to transport the produced caisson to the place of use.

1 is a perspective view showing a general caisson manufacturing site. In addition, FIG. 2 is a view showing a picture of the ocean port during reclamation construction through a caisson, FIG. 3 shows a picture of the view after installation of the port quay wall, and FIG. 4 shows a schematic cross-section of the on-site pier structure.

As shown in FIG. 1, a moving stage is provided in the caisson manufacturing site to prepare for manufacturing and to move hydraulic jacks and bogies (STEP1). And, a moving passage having a certain depth and width on both left and right sides is formed with a certain straight length from the inland side toward the sea level. In addition, a transfer rail through which the bogie can be moved is installed in this moving passage.

In addition, a first step portion for manufacturing the base slab 1B of the caisson is provided at a position connected to the moving stage toward the sea level (STEP2).

On the other hand, a second step part is located in front of the first step part toward the sea level along the moving passage. When the base slab manufactured in the first step part moves to the second step part, the second step part moves to the upper part of the base slab, and the like. After pouring, cure to make a caisson (STEP3).

As described above, the caisson manufactured in the second step portion is transferred to the third step portion located in front of the second step portion, and in the third step portion, finishing operations such as calibration work and waterproofing agent coating work are performed.

The completed caisson is transferred from the third step to the floating dock located at sea level (STEP4), and the caisson is transported to the installation site by floating the floating dock ship on the sea level and moving it.

In general, the caisson corresponds to a structure that is essentially used in port construction. For example, it is applied to important facilities in ports such as gravity-type quay walls and caisson breakwaters.

In addition, the sea level has recently risen due to global warming and the design wave height is rapidly increasing, so if not appropriately responding to these changes, the possibility of leading to a large-scale accident is gradually increasing.

Currently, breakwaters are increasing in size as the design wave height increases, but the reality is that they are struggling to prepare alternatives because they do not know when the 50-year design wave or more will invade.

In other words, there is an urgent need for a plan to actively cope with changes in port logistics conditions such as an increase in design wave height due to climate change and an increase in ship size, that is, a plan to cope with the increase in horizontal force.

Therefore, a caisson manufacturing system and a manufacturing method thereof that can increase the resistance to horizontal loads of waves or earth pressure by increasing the friction between the caisson and the rubble mound were required.
