And a frame can be easily and inexpensively assembled on the basic concrete book.

[0003]

When the foundation concrete is provided at the bottom of the submerged structure as described above, it is inevitable that the weight of the submerged structure composed of the basic concrete and the frame increases. Therefore, there is a problem that the transport and installation work is difficult. In addition, since the frame body installed on the foundation concrete is formed by assembling a plurality of stages in a cross-girder form with a space between the upper and lower rods, a large space for one rod between the upper and lower rods. It is inevitable that a gap is formed. For this reason, when a small-diameter stone block is used as the stone block to be filled in the rod, there is a problem that the stone block easily flows out of the gap.

Further, since the upper and lower rods constituting the frame are merely connected to each other by the pillars set up at the four corners of the foundation concrete block, the connecting force of the steel rods constituting the pillars is loosened at all. In addition, there is a problem that the peripheral wall portion made of the frame is easily collapsed in accordance with the large pressing force given by the filler made of the stone blocks or the flow of the river.

[0005] In view of such circumstances, the present invention can easily perform a transport operation and an installation operation, and
It is an object of the present invention to provide a sediment structure capable of effectively preventing the collapse of the sediment structure, and effectively preventing the loss of the filler filled in the sediment structure.

[0012]

1 and 2 show an embodiment of a submerged structure according to the present invention. This submerged floor structure includes a bottom wall 3 formed by arranging a plurality of horizontal bars 2 at regular intervals on a pair of vertical bars 1 installed opposite to each other, and a bottom wall 3 formed by arranging the bottom walls 3. A pair of vertical bars 4 is installed on both ends of each of the horizontal bars 2 to be configured, and a pair of horizontal bars 5 is installed on both ends of the vertical bars 4. And a peripheral wall portion 6 configured by alternately stacking the horizontal bar members 5.

The vertical bars 1 and 4 constituting the bottom wall 3 and the peripheral wall 6 are 90 m in which a preservative is pressurized and injected.
It is composed of a round bar having a diameter of about m.
The horizontal bars 2 and 5 constituting the bottom wall portion 3 and the peripheral wall portion 6 are 120 mm in which a preservative is pressurized and injected.
It consists of a round bar with a diameter of about
As shown in FIG. 3, cutouts 7 corresponding to the peripheral surfaces of the vertical bar members 1 and 4 are formed on the upper and lower sides, respectively.

Then, as shown in FIG. 4, with the peripheral surfaces of the vertical bars 1 and 4 engaged with the notches 7 of the horizontal bars 2 and 5, the horizontal bars 2 and 5 and the vertical By inserting a connecting member 9 made of a threaded rod or the like into a prepared hole 8 made of a drilled hole or the like formed at the end of the rods 1 and 4 and screwing nuts 10 at both ends thereof, a peripheral wall portion is formed. 6, the end of the horizontal bar 5 is connected to the end of the vertical bar 4, and the end of each of the horizontal bars 2 forming the bottom wall 3 is connected to the vertical bar 1, 4. And the end of the horizontal bar 2 located at the outermost portion of the bottom wall 3 is connected by the connecting member 9.

After assembling the submerged structure 11 having the bottom wall portion 3 composed of the above-described vertical bar 1 and the horizontal bar 2 and the peripheral wall portion 6 composed of the vertical bar 4 and the horizontal bar 5, FIG. As shown in the figure, a filler 12 made of debris or the like is filled in the sedimentary structure 11, and the sedimentary structure 11 is submerged along the riverbank, thereby installing the sedimentary structure 11 for revetment of a river. Can be. In addition, as shown in FIG. 6, a plurality of sedimentation structures 11 are respectively installed along both banks of the river, and the sedimentation structures 1 are arranged on the left and right sides of the river.
If the installation positions of 1 are changed, the flow of the river can be meandered by these sinking structures 11.

A bottom wall 3 constructed by arranging a plurality of horizontal bars 2 at regular intervals on a pair of vertical bars 1 installed opposite to each other, and a bottom wall 3 A vertical bar 4 is installed on both ends of each horizontal bar 2 constituting the above, and a horizontal bar 5 is installed on both ends of the vertical bar 4 respectively. Since the sedimentary structure 11 composed of the peripheral wall portion 6 formed by alternately stacking the bars 5 is formed, the weight of the sedimentary structure 11 is reduced as compared with the case where a concrete material is used, and the transporting operation and the installation operation are performed. Can be easily performed.

Further, by setting the arrangement interval of the horizontal bars 2 constituting the bottom wall 3 to an appropriate value, the filler 12 filled in the sedimentary structure 11 falls off the bottom wall 3. Can be prevented. Furthermore, the above-mentioned submerged structure 1
1 through a gap formed in 1
A sufficient contact area with water can be ensured, so that algae can be attached to the filler 12 to effectively promote its inhabitation, and the bottom wall 3 can be effectively used as a fish reef. be able to.

A notch 7 corresponding to the other peripheral surface is formed at both ends of the horizontal bar members 2 and 5.
Since the vertical bar members 1 and 4 and the horizontal bar members 2 and 5 are configured to be connected by the connecting member 8 in an engaged state,
The vertical bar members 1 and 4 and the horizontal bar members 2 and 5 are maintained in a stable connected state, and are pressed according to the pressing force of the filler 12 made of debris and the like filled in the submerged structure 11 or the flow of the river. It is possible to effectively prevent the bottom wall portion 3 and the peripheral wall portion 6 from collapsing due to the applied pressing force.

That is, the peripheral surfaces of the vertical bars 1 and 4 are engaged with the cutouts 7 of the horizontal bars 2 and 5 to restrict the movement of the vertical bars 1 and 4 and to prevent the vertical bars 1 and 4 from moving. , 5 are engaged with the notches 7 in surface contact with the peripheral surfaces of the vertical bars 1, 4 so that the movement of the horizontal bars 2, 5 is restricted. Since the horizontal bars 2 and 5 and the vertical bars 1 and 4 are connected by the connecting member 9, even when the connecting force of the connecting member 9 is slightly weakened, the horizontal bars 2 and 5 and The vertical bars 1 and 4 can be maintained in a stable engagement state. Therefore, the horizontal bars 2 and 5 and the vertical bars 1 and 4 are pushed outward by the filler 12,
Alternatively, even when pushed by the flow of a river, the horizontal bars 2 and 5 and the vertical bars 1 and 4 constituting the bottom wall portion 3 and the peripheral wall portion 6 of the sedimentation structure 11 are separated and collapse. The occurrence of a situation can be effectively prevented.

Further, the vertical bars 4 and the horizontal bars 5 are alternately stacked with the peripheral surfaces of the vertical bars 4 engaged with the cutouts 7 formed in the horizontal bars 2 and 5. Thereby, the upper vertical bar 4 and the lower vertical bar 4 can be arranged at positions close to each other, and the upper horizontal bar 5 and the lower horizontal bar 5 are arranged at positions close to each other. Therefore, it is possible to prevent a large gap from being formed between the upper and lower vertical bars 4 and 4 and between the horizontal bars 5 and 5, and to effectively prevent the filler 12 from flowing out from the gap. Can be prevented.

For example, in the case where the vertical bar 4 having a diameter of 90 mm and the horizontal bar 5 having a diameter of 120 mm are used as described above, if the notch 7 is not provided, the interval between the upper and lower vertical bars 4 is not required. Is 120mm and the upper and lower horizontal bars 5,5
Is 90 mm. On the other hand, when the notch 7 having a depth of 30 mm is formed above and below the horizontal bar 5, the interval between the upper and lower vertical bars 4 and 4 becomes 60 mm, and the upper and lower horizontal bars 5 and 5 are formed. Is 30 mm, so that the distance can be significantly reduced as compared with the case where the notch 7 is not provided. By changing the depth of the notch 7 to various values, a gap formed between the upper and lower vertical bars 4 and 4 and a gap formed between the horizontal bars 5 and 5 are obtained. Can be adjusted to any values.

In the above embodiment, the notch 7 is formed only in the horizontal bars 2 and 5 having a larger diameter than the vertical bars 1 and 4. Since the horizontal bar members 2 and 5 are configured to be engaged and connected to each other, the structure of the submerged structure 11 can be simplified and the manufacturing cost can be reduced without significantly lowering the strength of the submerged structure 11. There is an advantage that the connecting work between the bars 1 and 4 and the horizontal bars 2 and 5 is facilitated and the assembling work can be performed in a short time.

That is, the notch 7 may be formed in the vertical bars 1 and 4 instead of the horizontal bars 2 and 5. In this case, since the diameter of the vertical bars 1 and 4 tends to be remarkably reduced at the installation portion of the cutout portion 7 and the strength of the submerged structure tends to be greatly reduced, the horizontal bars 2 and 5 having a large diameter are used. It is desirable to have a structure in which the notch 7 is formed. Notch portions 7 corresponding to both the vertical bars 1 and 4 and the horizontal bars 2 and 5.
In the case where the notches are provided, the processing of the notch 7 is complicated, and the notches 7, 7 formed in the vertical bars 1, 4 and the horizontal bars 2, 5 are accurately engaged. Therefore, it is preferable that the notch 7 is formed only in the horizontal bars 2 and 5 having a larger diameter than the vertical bars 1 and 4 as described above.

Further, the total length of the vertical bars 1 and 4 and the horizontal bars 2 and 5 may be changed to various values in accordance with the installation range of the submerged structure 11. When the length of the vertical bar members 1 and 4 is significantly larger than the length of the horizontal bar members 2 and 5, as shown in FIGS. A horizontal bar 13 for reinforcement between the members 5 and 5
It is desirable that the arrangement of the slab prevents the deformation of the submerged structure 11. In addition, the said vertical bar material 1,
By making the diameter of 4 larger than that of the horizontal bars 2 and 5, the deformation of the submerged structure 11 may be prevented.

In addition, round bars having various lengths are used in combination as the vertical bars 4 and the connecting position between the upper vertical bars 4 and the lower vertical bars 4 is shifted left and right. In this case, even when the total length of the sedimentation structure 11 is increased, its strength can be sufficiently ensured. For example, as shown in FIG. 9, a short vertical bar 4a having a length of about 1 m, a medium vertical bar 4b having a length of about 1.5 m, and a length having a length of about 2 m. By appropriately selecting and arranging the vertical bar members 4c of the length, the cut of the vertical bar member 2 located at the upper stage and the vertical bar member 4 located at the lower stage are formed.
By preventing the notch from overlapping with the same position, the occurrence of a situation in which the peripheral wall portion 6 formed by the vertical bar 4 is divided right and left in accordance with the pressing force of the filler 12 is effective. Can be prevented. In addition, as shown in FIG. 9, a half bar-shaped horizontal bar material 1 is provided at the lowermost portion of the bottom wall portion 3 in order to improve the stability when the submerged structure 11 is installed.
4 may be provided.

One is the upper vertical bar 4e
Alternatively, it is desirable to configure so as to overlap with the lower vertical bar 4f. With this configuration,
The pressing force of the filler 12 acting on the ends of the vertical bars 4d, 4d from the inner surface side of the peripheral wall portion 6 is applied to at least the upper vertical bar 4e or the lower horizontal bar 4f via the additional wood 15. By transmitting the pressing force to one side, the pressing force can be dispersed vertically and effectively supported. Therefore, it is possible to effectively prevent the end portions of the vertical bar members 4d, 4d from being deformed by being pushed outward by the filler 12.

As shown in FIG. 12, an engaging groove 17 extending in the longitudinal direction of the horizontal bar 5 is formed in the upper and lower surfaces of the horizontal bar 5 constituting the peripheral wall portion 6. And a cover plate 18 having upper and lower ends fitted in the engagement grooves 17 to cover a gap formed between the upper and lower vertical bars 4, 4. In the case of such a configuration, the gap formed between the upper and lower horizontal bar members 5 is covered with the covering plate 18 so that the filler 12 can reliably flow out of the gap. There is an advantage that it can be prevented. In addition, the vertical bar 4 constituting the peripheral wall portion 6
An engaging groove extending in the longitudinal direction of the vertical bar 4 is formed in the upper surface and the lower surface of the, and both upper and lower ends are fitted in the engaging groove between the upper and lower horizontal bars 4. It is good also as a structure which provided the covering board which is provided.

As the above-mentioned vertical bar and horizontal bar, square bar 2
When the square bars 21 and 22 are arranged such that one diagonal line of the cross section thereof is oriented vertically as shown in FIG. 15, as shown in FIG. The weight can be effectively reduced and the material cost can be reduced as compared with the case where the opposed wall surfaces of the square bars 21 and 22 are oriented in the vertical direction. .

That is, as shown in FIGS. 15 and 16, the square bars 21 and 22 are arranged so that one diagonal line of the cross section thereof is oriented in the vertical direction. A right-angled triangular notch 7 corresponding to the corner of the material is formed in the corner of the horizontal bar made of the square bar 22, and the square bars 21 and 22 are engaged in the notch 7. If done, square bar 2 of the same size
As shown in FIG.
The vertical dimension of the vertical bar and the horizontal bar is about 1.4 in comparison with the case where the opposing wall surfaces of the 22 are oriented vertically.
Because it can be set twice, the number of vertical bars and horizontal bars used can be reduced, or the diameter of the materials used can be reduced, so that weight can be effectively reduced and material costs can be reduced. There is an advantage.

In addition, as shown in FIG. 17, the upper and lower horizontal bars 2 and 5 are all set to the same length to form a rectangular parallelepiped sedimentation structure 11 as shown in FIG. , The overall length of the horizontal bar 5 constituting the peripheral wall portion 6 may be gradually increased. In the case of such a configuration, the rear surface portion of the sinking structure 11 can be inclined in correspondence with the inclined surface 23 on the riverbank. FIG.
