2. Description of the Related Art Conventionally, the coastal area along the coastline has been considered to be the first to be protected against wave forces, so that it is constructed by a revetment structure combining a large number of concrete blocks. It was often done.

By the way, this type of revetment structure is not suitable for the surrounding environment because it has an artificial feeling, and the wall surface is often vertical, which makes it difficult to approach the waterside. The natural stones are put on the surface of the structure or the slope of the structure is made into a staircase so that the slope is gentle. However, in the case of the former, it is difficult to obtain the necessary natural stones, and the latter. In the case of, there was a problem that the image as an artificial structure remained.
Therefore, recently, it has been considered to install the structure using pseudo-rock processed by imitating the surface of the main body of the structure (structure) made of concrete etc. to resemble the texture of natural stone, etc. Various problems to be solved such as shortening of sea work and countermeasures against waves have been pointed out and have not been realized yet.

[0004]

According to the present invention, a large number of pseudo rock unit members are fixed on the top edge of a substructure, and an inner concrete surrounded by these pseudo rock unit members is poured to form a solid concrete. A first step is formed by integrating the filled concrete and the pseudo rock unit member, and then a pseudo rock unit member similar to these pseudo rock unit members is formed on the pseudo rock unit member forming the first step. After arranging and fixing, fill concrete inside to form the second step, form the final step by the same procedure, and further close the top opening of the final step to build It is intended to provide a method of constructing a structure using pseudo rock that is easy to use and that is compatible with the surrounding environment.

In this case, as the pseudo rock unit member, a pseudo rock panel formed as a natural stone-like surface by spraying concrete onto a base formed by reinforcing bars and wire mesh attached to the steel frame member, or a natural stone on the steel frame member It is possible to use a pseudo rock panel in which a plate-shaped rock piece formed by using as a mother mold is attached and joint treatment is performed.

Further, as a pseudo rock unit member,
A rectangular parallelepiped steel frame is placed in the casting formwork, and a wire mesh is stretched on one side of this steel frame.After concrete is placed in the casting formwork, concrete is sprayed onto the wire mesh surface to naturally A pseudo-rock block formed as a stone-like surface or a plate-shaped rock piece formed by using a natural stone as a mold is attached to one side of a rectangular parallelepiped steel frame to perform joint treatment, and the remaining side is closed with a casting formwork. A pseudo rock block formed by pouring concrete inside can also be used.

[0007]

[Operation] According to the method for constructing a structure using pseudo rock according to the present invention, a pseudo rock unit member fixed around the top edge of a substructure and on each step is used as a formwork to form a filled concrete. Since the construction is carried out, not only the construction work can be facilitated, but also the cost and the construction period can be shortened, and further, not only the landscape but also the structure with improved hydrophilicity can be obtained.

EXAMPLES Next, as a preferred example of a method for constructing a structure using pseudo rock according to the present invention, a case of constructing a jetty (hereinafter referred to as an artificial shore) having a new hydrophilic space will be described with reference to the accompanying drawings. A detailed description will be given below with reference to FIG.

That is, when constructing such an artificial rock, first, floor digging is performed from the land and / or the sea at the place where the artificial rock is installed. In this case, floor digging from land is
If necessary, excavate from the base toward the tip while retaining the soil with steel sheet pile, etc. Then, the foundation rubble is thrown in from the portion where the floor excavation is completed, a predetermined stone thickness is secured, and if necessary, the foundation rubble is leveled by using a diving worker or the like and the foundation 10
Are formed (see FIG. 1a).

Next, the foundation blocks 12 that have been formed in the shape of rectangular parallelepipeds in advance are installed in the planned construction parts of the structure on the foundation 10, and the landscape is adjacent to these foundation blocks 12 and at a water depth of 1 m to 2 m. Only the top end is formed as a pseudo rock in the part that has no influence on the use of hydrophilicity and the pseudo rock block similar to the pseudo rock block 38 or 40 described later with a gentle gradient of about 1: 5 to 1:10. Install as a rooting member. Then, on the outside of these rooting members, where the water depth is deeper, a normal covering stone 14 is put in for stabilizing the foundation, and the leveling work is appropriately performed to carry out the leveling work A.
To form. At this time, pay sufficient attention to the installation joint interval, height, etc. so as not to hinder the installation of the pseudo rock unit member described later. In addition, since the substructure A configured as described above has a gentle average gradient as a whole, and further, a recess or the like that forms a tide pool can be appropriately formed in the gentle gradient portion, so that a new space for utilizing hydrophilicity can be created. It will be.

Then, along the edge of the planned construction portion of the structure in the substructure A formed by a large number of foundation blocks 12 and pseudo rock blocks 38 or 40 as a rooting member, pseudo rocks are formed to suit the shape and design. Unit member 16
And the pseudo rock unit member 16 and the top end of the substructure A are integrated by an appropriate anchor means (FIG. 1b).
reference).

In this case, as the pseudo rock unit member 16, a pseudo rock having a natural stone-like surface is obtained by spraying concrete onto the base material 24 formed by the reinforcing bars 20 and the wire nets 22 attached to the steel frame member 18 manufactured at the factory. A pseudo-rock panel 32 that has been subjected to joint treatment after attaching a large number of plate-shaped rock pieces 30 formed from natural stone as a mold to a panel 26 (see FIG. 2) or a steel frame member 28 similarly manufactured in a factory. (See FIG. 3) can be preferably used.

The pseudo rock panels 26 and 32 have a high degree of freedom in shape and are easy to manufacture, but considering the degree of texture, the pseudo rock panels 26 are used in the case of constructing a scenic rock field with a distance from the viewpoint. The pseudo rock panel 32 is preferably used as a member for constructing an artificial surf and the like as in the present embodiment because a fine texture can be obtained.

As the pseudo rock unit member 16,
As shown in FIG. 4, a rectangular parallelepiped steel frame 36 is arranged in the casting mold 34, and a wire mesh 22 is stretched on one side of the steel frame 36 via a supporting rebar net to form the casting mold. After placing concrete in 34, use the pseudo rock block 38 having a natural stone-like surface by spraying concrete on the surface of the wire mesh 22, or, as shown in FIG. 5, one side of the rectangular parallelepiped steel frame 28. In addition, a number of plate-shaped rock pieces 32 formed by using natural stone as a master mold are attached to the joints, and the remaining side surface is closed by a casting mold 34, and concrete is placed inside the pseudo-rock. Block 40 can be used.

The pseudo rock block 3 formed in this way
Although 8 and 40 require a large number of manufacturing steps, they are highly stable as a single body and therefore can be suitably used in a place where a large wave action occurs.

In this way, the gap portions of the pseudo rock unit members 16 arranged and fixed along the edge on the substructure A are subjected to joint treatment with mortar or the like, and the inside surrounded by these pseudo rock unit members 16 Then, the filling concrete 42 is placed by using a concrete pump truck or the like to integrate the pseudo rock unit members 16 and the filling concrete 42 to form the first step portion 44 (see FIG. 1c).

Next, a similar pseudo-rock unit member 22 is circumferentially provided on the first step portion 44 through an appropriate anchoring means, and fixed, and then a solid concrete 42 is placed inside the second step portion. 46 is formed. Then, similarly, in the same manner, the final step portion 48 shown as the third step portion in this embodiment is sequentially formed, and the top end 50 of the final step portion 48 is closed by the pseudo rock unit member 16 (or color mortar). Construct an artificial surf (see Figure 1d).

It should be noted that the artificial rock is worked toward the base while it is completed from its tip, and the artificial rock unit member 16 fixed on the substructure A and each step is the shape and design of the entire artificial rock to be constructed. It goes without saying that they are appropriately arranged according to the above. Finally, joint finishing between the pseudo rock unit members 22 is performed, and unnecessary portions of the substructure A are backfilled with sand or the like.

[0019]

As described above, according to the method for constructing a structure using pseudo rock according to the present invention, the pseudo rock unit can be attached and fixed and the filling concrete can be placed in a short time, which is easy. Can be built into.

Further, since the pseudo-rock structure itself has a surface texture very close to that of natural stone, it not only matches the surrounding environment as compared with the conventional exposed structure of concrete but also cannot be used conventionally. The basic part of the structure can be used as a new hydrophilic space.
Also, since pseudo rock unit members fixed around the top of the substructure and on each step can be used as the formwork in each case, it is possible to reduce construction costs and shorten the construction period. Have.

The preferred embodiment of the method for constructing a structure using pseudo rock according to the present invention has been described above with reference to the accompanying drawings.
