Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing an underwater structure such as a caisson, and more particularly, when manufacturing an underwater structure such as a caisson, the weight of the structure is provided separately from a friction increasing member. Supported through the support member,
The present invention relates to a method of manufacturing an underwater structure provided with a friction increasing member that can be accurately performed and that does not apply an excessive load to the friction increasing member during manufacturing of the structure.

[0002]

2. Description of the Related Art Underwater structures such as breakwaters and quays are manufactured in land construction yards, etc., and then hoisted by a crane or the like to be launched and towed to the construction site. , A method of submerging on a supporting foundation such as a rubble foundation constructed on the seabed is used. In addition, a rubble foundation is built in advance on the seabed where the caisson is constructed, and a breakwater or the like is made in a state where the caisson is placed on the rubble foundation. As mentioned above, when constructing an undersea structure such as a caisson on the foundation of the seabed, if the lower surface of the caisson is placed directly on the rubble foundation, the bottom surface of the stone and the caisson will be Has a small friction coefficient, there is a problem that the caisson easily moves due to the influence of waves.

Therefore, in order to hold underwater structures such as caisson in a stable state on a foundation constructed on the seabed,
Traditionally, asphalt mats have been placed on the underside of caisson. As mentioned above, as a method of placing the asphalt mat on the lower surface of the caisson, there is a method of placing the asphalt mat on the upper surface of the foundation built on the seabed and then placing the caisson, and attaching the asphalt mat integrally to the lower surface of the caisson. In addition, a method of placing it on the foundation as it is is used. As a method of integrally providing an asphalt mat on the lower surface of the caisson,
For example, the method as disclosed in Japanese Patent Laid-Open No. 4-176913 is used.

In the above-mentioned conventional example, after the base portion of the steel caisson is manufactured, the base member is inverted to position the bottom plate upward, and the asphalt mat is constructed on the bottom plate. . Then, after the friction increasing member made of the asphalt mat is integrally constructed, the base member is inverted again to return to the normal position, and the caisson body is connected to the upper portion of the base member to construct the structure. . Then, by using the caisson construction method as described above, on the lower surface of a structure such as a large caisson,
It is said that the asphalt mat can be attached accurately and that the support condition when constructing a structure on the seabed foundation can be made reliable.

[0005]

However, as in the above-mentioned conventional example, the method of reversing the base member during the manufacturing of the steel caisson to construct the asphalt mat as the friction increasing member is a large caisson. It is necessary to invert the components using a large crane. Therefore, there is a problem that the caisson cannot be manufactured unless it has a large crane and a large site such as a shipyard or a factory corresponding to a large steel structure. Further, in the above-mentioned conventional example, when the caisson main body is overlaid on the member at the base of the caisson and there is unevenness in the building yard, the portion located at the projecting portion is deformed by receiving a concentrated load. There is also a problem that a part of it is strongly compressed and deformed due to an unbalanced load.

Separately from the caisson manufacturing method, asphalt mats are spread in caisson building yard,
When constructing the upper structure, the load during manufacturing of the caisson is directly applied to the asphalt mat. And when a large load is locally applied to the asphalt mat, a part of the asphalt mat is compressed and deformed, and when the caisson was built on site,
The problem arises that the caisson cannot be supported with a uniform thickness with respect to the foundation. Further, when a large compressive force is applied to a part of the asphalt mat during the production of the caisson, the asphalt mat may be broken, which causes a serious problem in the reliability of the asphalt mat. Further, when the asphalt mat is locally deformed by the local load, when building the upper part of the caisson,
Distortion or the like occurs, which is a precision problem.

[0007]

It is an object of the present invention to solve the above-mentioned problems in attaching a friction increasing member to a conventional caisson or the like, and to provide an opening provided with a member for supporting the load of the caisson on the friction increasing member. It is an object of the present invention to provide a method of manufacturing a caisson in a state in which a load during manufacturing of the caisson is supported by a load supporting member that is separate from the friction increasing member.

[0008]

According to the present invention, a friction increasing member is arranged on a ground for manufacturing an underwater structure, and a separate supporting member is arranged at a position where a part of the friction increasing member is removed. In the state of supporting the load of the underwater structure via the support member,
The method of constructing the underwater structure is used. Further, in the present invention, a notch formed by cutting from a peripheral portion of the friction increasing member provided in the underwater structure is formed, and a support member for bearing the load of the structure is arranged in the notch, and the support member is A method of constructing the underwater structure can be used while supporting the load of the underwater structure via the above. Further, in the present invention, a hole is formed at a position for bearing the load of the structure on the friction increasing member provided in the underwater structure, and a support member for bearing the load of the structure on the hole is arranged. However, it is possible to use the method of constructing the underwater structure in a state of supporting the load of the underwater structure via the support member.

In addition to the above method, in the present invention, a hole is formed at a position for bearing the load of the structure on the friction increasing member provided in the underwater structure, and the load of the structure is applied to the hole. In the state of arranging a supporting member that bears the load, filling the hole with the same material as the friction increasing member to integrate the supporting member and the friction increasing member, and supporting the load of the underwater structure through the supporting member. It is also possible to build the underwater structure.

[0010]

As described above, according to the present invention, the caisson that constitutes a quay, a breakwater, etc. is mounted on land with a friction-increasing member such as an asphalt mat or a rubber mat integrally attached to the lower surface thereof. At the time of manufacturing, the weight of the caisson during manufacturing is not directly applied to the mat member, so that the mat member can be prevented from being unevenly compressed. Further, in the present invention, with respect to the mat built in the land caisson construction yard, notches and holes are arranged at a predetermined interval, and a support such as a support block is arranged in a part without the mat, By placing the skeletal members of the caisson on the support to bear the weight of the caisson during its manufacture, the mat part will not have a large compressive action. Further, a supporting member may be arranged in an inner hole formed at an arbitrary position of the mat member by using an adhesive means so as to be integrated with the mat member, or a supporting member may be arranged in a state where the hole remains in the mat member. It is possible to use any means such as the above, and the manufacturing work of the caisson body can be easily performed even when manufacturing a large structure.
