2. Description of the Related Art Conventionally, when constructing a double wall structure such as a wall structure, a large number of wall members such as steel sheet piles are usually mounted by using a vibrating hammer or the like. It was built by penetrating into.
In the conventional concrete caisson method, a concrete precast box is placed on a mound, and then the box is filled with earth and sand to construct a gravity structure such as a breakwater or a quay.

[0003]

However, in the above-mentioned conventional means for constructing a double-walled structure, particularly, the construction site where noise, vibration and the like must not be generated, and the foundation ground (mound) are not included. In construction sites such as bedrock, it has been difficult to drive the wall component into the mound using a vibration driving device. In addition, the construction work also required a great deal of time and labor. In the case of the concrete caisson method, a method of assembling reinforcing steel in a yard, installing a formwork, pouring concrete, and manufacturing a reinforced concrete box is adopted. , And required a great deal of effort.

The present invention has been made in view of the above circumstances, and does not drive a wall component into a mound and penetrates the same, and requires a long and enormous amount of labor for manufacturing a box like a concrete caisson method. It is an object of the present invention to provide a wall structure capable of easily constructing a long double-wall structure having a high construction accuracy in a relatively short construction period without requiring the construction.

A bottom plate is arranged. Further, in the invention according to claim 3, the bottom plate is made of a sheet material. According to a fourth aspect of the present invention, in the wall structure according to the second aspect, the bottom slab is made of non-reinforced concrete or reinforced concrete. According to a fifth aspect of the present invention, in the wall structure according to the first, second, third or fourth aspect, a side wall supporting member for supporting the side wall is provided at a predetermined position in the height direction of the box. It is characterized by having.

According to a sixth aspect of the present invention, in the wall structure according to the first, second, third, fourth or fifth aspect,
A retaining wall support member for supporting the retaining wall is provided at a predetermined position in the height direction of the box. Furthermore, in the invention according to claim 7, in the wall structure according to claim 5 or 6, ends of the side wall support member and the stop wall support member protruding outside the box are covered with an anticorrosion member. It is characterized by having. According to an eighth aspect of the present invention, in the wall structure according to any one of the first to seventh aspects, a partition is disposed between the front and rear stop walls of the box.

For example, partition walls 17, 17 constituted by joining steel sheet piles with joints in series with each other are arranged, or as shown in FIG. 15 (b), between the side walls 3, 4 of the box 2 and the stop wall 5, , 6 between the partition walls 17, 17 formed by joining steel sheet piles with joints in the same manner as described above in series. The partition walls 17 at the intersections are joined by welding or the like.

In the above embodiment, the case 2
The bottom slab 10 for closing the inner bottom surface 2a is made of non-reinforced concrete or reinforced concrete. However, a sheet material such as a civil engineering sheet may be used. In this case, the lower ends of the opposing side walls and the retaining wall are opened outward. In order to avoid such a situation, the support may be made by a tensile material such as a tie rod, a tie rope, or a reinforcing bar.

When the upper end 2b of the box 2 is covered with a time-hardening material 16 such as reinforced concrete or concrete, as shown in FIG. It is also possible to form a reinforced concrete floor slab or a time-hardening material 16 such as concrete in the form of a cap to form a beam structural material.

In practicing the present invention, the corner member 7 is replaced with a steel pipe sheet pile with a joint as shown in FIG.
You may make it use the jointed deformed steel sheet pile 7a provided with the joint which continued in the up-down direction in the both sides of the plane W shape sheet pile main body. In addition, as the joint form of the joints, a pipe type female pipe with a female joint with a slit is used for the corner member 7, and the side wall constituting members 31, 41 or the stop wall constituting members 51, 61 connected to this are used as the joint members. What is necessary is just to provide the male joint of a T-shaped end cross section. Of course, other known joint structures can be employed, and in this case,
Water swellable fillers or fillers for waterproofing such as concrete or mortar can be used.

In practicing the present invention, the precast cylindrical box 2 may be transported and placed on the ground without performing the work of penetrating the lower part of the box 2 into the ground.

[0027]

As described above, according to the present invention, the wall and the side wall forming the box as the wall structure are formed by a large number of wall component members and the mutual corners of the wall and the wall. And a hollow member is filled with a filling material to a predetermined height, and in the present invention, particularly, in the present invention, as in the prior art, the mound has side wall components and stoppers. The wall structure can be easily constructed in a short period of time without driving and penetrating the wall components and the corner members. In the case of the present invention, since the side wall, the retaining wall and the bulkhead only need to be fitted and erected with the joint of the wall member such as a steel sheet pile, the production time is shorter and the labor is saved as compared with the concrete caisson method. Can be achieved. Further, when the bottom plate is made of a sheet material or non-reinforced concrete or reinforced concrete, leakage of the filling material from the lower part of the box can be prevented. The member and the stop wall constituting member can be integrated with the corner member as required. Further, when the side wall support member or the stop wall support member is provided as in claims 5 and 6, the side wall or the stop wall can be supported, and even if a horizontal force acts in the event of an earthquake or the like, the filling is performed. The shear deformation of the soil and the top displacement of the structure can be reduced. Therefore, the width of the structure can be reduced, and when the underwater ground H is soft, the ground improvement width can be reduced. Furthermore, when the end portions of the side wall support member and the stop wall support member that protrude to the outside are covered with an anticorrosion member, the end portions of the side wall support member and the stop wall support member are reliably anticorrosion. Thus, the anticorrosion performance of the wall structure can be improved. Further, when the partition wall is arranged as in claims 8 and 9, the box can be reinforced, and a box or wall structure having high rigidity can be obtained. Further, the partition wall can prevent the horizontal force at the time of a horizontal earthquake or the like from being dispersed and prevent an excessive horizontal force from acting on the side wall or the stop wall. Further, when the upper part of each side wall or the upper part of each retaining wall is covered with a time-curable material, the upper part of each side wall or the upper part of each retaining wall can be protected from corrosion.
