[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure of a structure having a plurality of vein-like internal cavities, and more particularly, to a connection support that is firmly erected on an upper surface portion of a support and an embankment is provided on an upper surface of an upper member. When performing and constructing a multi-arch type structure, the flow of the embankment is reliably prevented by the landscape panels arranged between the connecting columns, and the solidity is not impaired, and the top surface of the embankment is almost flat The present invention relates to a support structure of a structure having a plurality of vein-like internal cavities that can be effectively used.

[0002]

2. Description of the Related Art A structure having a vein-shaped internal cavity can form a large cross-section of the vein-shaped internal cavity, and is used for a tunnel section for crossing under a highway or a tunnel in a mountainous area. ing.

[0003] In addition to the single arch type having one pulsating internal cavity, the structure also includes a multi-arch type having a plurality of pulsating internal cavities.

[0004]

By the way, in a conventional structure having a plurality of vein-like internal cavities, that is, a column structure of a multi-arch type structure, an arch-shaped upper member is provided between the columns. At this time, a part of the column is not protruded above the upper member.

[0005] As a result, when a multi-arch type structure is constructed by embankment on the upper surface of the upper member and a tunnel portion for crossing under the expressway, there is a fear that the expressway collapses due to the flow of the embankment. However, there is an inconvenience that the robustness is impaired.

In order to prevent the embankment from flowing down, a configuration may be considered in which a panel is disposed vertically on the upper surface of the upper member. However, the panel cannot be firmly supported, and improvement has been desired.

[0007]

SUMMARY OF THE INVENTION In order to eliminate the above-mentioned disadvantages, the present invention forms a vein-like internal cavity with a column and an arch-shaped upper member provided between the columns. In a structure in which a plurality of vein-like internal cavities are formed in a side-by-side state, a connecting column is placed and provided on a column supporting the upper member, and fixing means for fixing the column and the connecting column is provided. It is characterized by.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION
When the connecting column is firmly erected on the upper surface portion of the column by the fixing means and the multi-arch type structure is constructed by filling the upper surface of the upper member, the flow of the bank is arranged between the connecting columns. In addition to the landscape panels, this is reliably prevented, and the top surface of the embankment is made almost flat for effective use.
