Therefore, the bag material wears and breaks early due to repeated movement of the filling material by external force.
The structure for civil engineering disclosed in <2> Patent Document 3 encloses the filling material in a state where a certain degree of movement is allowed, in order to ensure the followability to non-landing.
Therefore, when a large wave force or the like acts, the filling material moves inside the bag, and the bag still has a problem of breakage.
In the civil engineering structure of <3> Patent Document 3, the tightening force of the intermediate connection material is not evenly transmitted to the entire bag body.
Therefore, the restraining force of the filling material by the bag body becomes weaker as it gets away from the filling material, and the restraining effect of the filling material varies.
The structure for civil engineering work of <4> patent document 4 can not obtain sufficient restraint of the inner packing material 83 because the rigidity of the bottom surface 81 of the rectangular parallelepiped bag 80 is low. The peripheral part hangs down centering on the central part of, and the shape of the rectangular parallelepiped before lifting shown with a dashed-two dotted line can not be maintained.
In particular, the longer the rectangular parallelepiped bag 80 is longer, the easier it is for the civil engineering structure to be deformed.

In this example, the columnar hard keeper 27 is accommodated in the central hole 21 surrounded by the inner side surface 24. However, when the rigid keeper 27 inserts the filling material 40 into the rectangular bag 20, the central hole 21 is Since it is only a mold material for securing, it is not essential and may be omitted.

<3.2> Dimensions of the Square Bag In this example, the height of the square bag 20 is smaller than the length of one side of the square bag 20, but the height of the square bag 20 is one side of the square bag 20. It may be the same as or longer than the length. Each dimension of the vertical and horizontal heights of the rectangular bag 20 is appropriately selected in accordance with the use of the civil engineering structure A and the type of the filling material 40.
The length of one side of each side surface of the inner side surface 24 is appropriately selected according to the use of the civil engineering structure A.

Material of <3.3> Square Bag The square bag 20 may be a mesh made of a synthetic fiber having excellent flexibility and durability, a sheet, or a combination thereof. It may be a water-permeable or water-impermeable (water-impermeable) material, or an elastic or non-elastic material.
The material of the rectangular bag 20 is appropriately selected according to the use of the civil engineering structure A and the type of the filling material 40.

<4> Holding Band The holding band 40 is a member which can be held by winding the entire circumference of the civil engineering structure A in the longitudinal direction through the central hole 21 and is a member of the upper cover 25 of the rectangular bag 20. It has a locking function, a holding function of the filling material 40 through the square bag 20, and a lifting function of the civil engineering structure A.
The proximal end of each holding band 40 is integrally fixed to each side surface of the inner side surface 22 of the rectangular bag 20 by stitching, fusion or adhesion.
At the tip of each holding band 40, a lifting loop 31 is formed.

<4.1> Material of Holding Band The holding band 40 is made of a flexible fiber, a resin, etc., and the form thereof is not limited to the illustrated belt-like material but may be a rope-like material or a string-like material. Good.

<4.2> Full Length of Holding Band The holding band 40 has a total length capable of winding one round or a plurality of rounds of the entire circumference of the civil engineering structure A via the central hole 21.

<4.3> Fixing Position of Base End of Holding Band In this example, a mode in which the base end of each holding band 40 is fixed to the inner side surface 22 of the rectangular bag 20 will be described. The fixed position of the end is not limited to this form.
As another form, the proximal end of each holding band 40 is fixed across the two surfaces of the bottom surface 23 and the inner surface 22 of the rectangular bag 20, or the outer surface 24, the bottom surface 23, and the inner surface of the rectangular bag 20. It is also possible to fix over 22 three sides.
The point is that the proximal end of each holding band 40 is fixed to a part of the rectangular bag 20 excluding the upper lid 25, and the tip (free end) side of the holding band 40 can extend upward through the central hole 21. If it is

<5> Filling material The filling material 40 is a hard granular material which is not compressively deformed, and, for example, aggregates such as crushed stone and cobbles, lightweight aggregates, concrete shells, granulated matter of incineration ash, soil, etc. can be used.
The material, specific gravity, size and the like of the filling material 40 are appropriately selected in accordance with the use of the civil engineering construction structure A.

[Method of producing structure for civil engineering work]
Next, an example of a method of producing the civil engineering work structure A will be described.

<1> Filling of filling material (Fig. 5)
With the upper opening of the rectangular bag 20 open, the filling material 40 is filled until the entire space 26 is full.
The holding band 30 and the upper lid 25 are removed so as not to disturb the work during the filling work of the filling material 40.
In addition, when the three-dimensional shape of the rectangular bag 20 is maintained using a manufacturing frame (not shown), the filling operation of the filling material 40 can be smoothly performed.

<2> Closing the upper lid (Figure 5)
Next, the upper lid 25 of the square bag 20 is put on it to close the storage space 26.
In order to finally lock the upper lid 25 with the holding band 30 closed, a dedicated locking means for fixing the upper lid 25 is unnecessary.

<3> Wrapping band (Fig. 3, 4)
Next, each holding band 30 extending upward from the central hole 21 of the rectangular bag 20 is wound around the outer peripheral surface of the rectangular bag 20 vertically or horizontally, and the tip of each holding band 30 is formed as a central hole Pull out from 21 upwards.
At this time, the holding band 40 is inserted into the positioning member 28 provided on the outer surface of the rectangular bag 20 to restrict the lateral movement of the holding band 40.
Alternatively, a spacer may be provided in advance on the support surface of the production frame that supports the bottom surface 23 of the rectangular bag 20, or a strip-shaped notch may be provided in advance on the support surface of the production frame. The holding band 40 can be easily wound using a band-like insertion space formed therebetween.

<4> Tightening of holding band (Fig. 6)
The loops 31 of the holding bands 30 extending upward from the central hole 21 are moored on the hooks of a crane and lifted to complete the construction of the civil engineering structure A.
When the loops 31 of the holding bands 30 are lifted, the holding bands 30 slide by means of the weight of the inner packing material 40, and the inner packing material 40 is tightened in an area via the square bag 20.
Therefore, the filling material 40 tightened through the rectangular bag 20 and the plurality of holding bands 30 is transformed into a non-deformable rectangular hard mass 40 a.
Since the self-weight can be used to clamp the filling material 40, a dedicated clamping device is not necessary.

  The civil engineering structure A manufactured in this manner is transported to the installation site as it is or temporarily placed in a stock yard, and used for desired civil engineering work on the ocean or on the land.

<5> The reason for the high restraint effect of the filling material The present invention does not cover only the outer periphery of the filling material like the conventional civil engineering construction structure with a bag, but it is also possible to belt the bottom of the bag It is not a structure that is lifted and supported by a member.
In the present invention, the rectangular bag 20 covers and restrains the entire inner and outer peripheries of the inner filling material 40 enclosed in a square ring shape, and a plurality of retaining bands 30 longitudinally wound and tightened on the rectangular bag 20 through the central hole 21. In combination with the above, the restraining effect of the filler 40 is enhanced.
That is, the holding band 30 can be surrounded across the four sides of the inner side surface 22, the upper lid 25, the outer side surface 24 and the bottom surface 23 of the rectangular bag 20, and these four sides can be tightened with an equal force. The clamping force by the holding band 30 is transmitted to the entire filling material 40 via the rectangular bag 20.
Therefore, not only the entire shape of the square can be maintained because the particles of the inner filler 40 mesh with each other (interlocking effect) not only at the surface of the inner filler 40 but also at the center thereof (interlocking effect) Bending strength, compressive strength, and shear strength become very high over the entire length of the square hard mass 40a.

<6> Reasons for Pulling out the Holding Band from the Center of the Civil Engineering Structure Body The holding direction of the holding band 30 which has passed through the center hole 21 of the holding bag 20 is reversed, and a plurality of holding bands 30 are obtained. It is also possible to pull out the tip of the tip from the outer side (outer side surface 24) side of the holding bag 20 and lift it.
When it is lifted in this state, a large bending moment works to cause the civil engineering structure A to be bent like a dish.
The warping of the civil engineering structure A causes loosening of the holding force when the civil engineering structure A is installed at a flat installation place.
On the other hand, when a plurality of holding bands 30 are pulled out from the center hole 21 of the holding bag 20 and lifted, the bending moment becomes small and the civil engineering structure A is effectively prevented from being bent in a dish shape. it can.

[Function of structure for civil engineering work]
<1> Prevention of breakage of square bag (Figure 3)
Since the above-described civil engineering construction body A can secure a large holding area of the filling material 40 by the square bag 20 compared to the conventional case, the free movement of the filling material 40 is reliably and effectively restrained. be able to.
Therefore, the wear of the rectangular bag 20 due to the free movement of the filling material 40 is prevented, and the durability of the rectangular bag 20 is significantly improved.

  For example, it is possible to restrain the outer peripheral surface of the filling material by filling the filling material fully in a simple bag and closing the top of the bag, but the contact area between the filling material and the bag It can not be secured large. For this reason, the binding force varies between the surface layer and the central portion of the filling material.

On the other hand, in the present invention, focusing on the contact area of the filling material 40 and the bag body, the holding of the filling material 40 is achieved by using the rectangular bag 20 having the central hole 21 and the plurality of holding bands 30 in combination. We secured a large holding area (restricted area).
When the civil engineering construction A of the present invention is compared with the conventional civil engineering construction in which the inner packing material is stuffed in a drawstring-like bag, if the amount of the inner packing material 40 in both constructions is the same. In the civil engineering structure A of the present invention, the holding area with the inner filler 40 becomes significantly larger than that in the prior art.
Therefore, in the civil engineering work structure A, not only does no variation occur in the holding power between the surface layer and the central portion of the hollow packing material 40, but also when the civil engineering construction structure A is installed in the ocean Since the free displacement can be reliably restrained, breakage due to abrasion of the rectangular bag 20 can be prevented for a long time.

<2> Prevention of deformation of civil engineering structure As described above, the holding (restraining) action of the inner filling material 40 by the civil engineering bag 10 is limited to the surface layer of the inner filling material 40 enclosed in the square bag 20. Instead, it is also transmitted to the central portion, and the inner filling material 40 is held face to face (restrained) to form the square hard lump 40a.
Therefore, not only the cross-sectional shape of the civil engineering structure A becomes difficult to deform, but the overall shape of the civil engineering structure A also becomes difficult to deform, so for example, even when installed at a site where large waves act. It becomes difficult for the civil engineering construction structure A to move from the installation location.

[Other embodiments]
Hereinafter, other embodiments will be described, but in the description, the same parts as those of the above-described embodiments are denoted by the same reference numerals, and the detailed description thereof will be omitted.

Example in which a plurality of holding bands are wound on one side of a <1> rectangular bag (FIG. 7)
In the above embodiment, although the holding band 40 is wound around each side of the rectangular bag 20 having a rectangular ring shape, a plurality of holding bands 40 are provided on each side of the rectangular bag 20. It is also possible to roll and lay in a row.
Although FIG. 7 shows a configuration in which two holding bands 40 are wound at intervals on each side of the rectangular bag 20, it may be three or more.
In addition, when the planar shape of the rectangular bag 20 has a rectangular shape, the number of windings of the holding band 40 on each side may be changed.
Fixing the proximal end of each holding band 40 to the inner surface 22 is the same as that of the previous embodiment.

In this example, since the holding range of the filling material 40 is expanded in the lateral direction, it is suitable when the civil engineering structure A is enlarged.
You may stick two or more.

<2> An embodiment in which the holding band is prevented from loosening The rectangular hard mass 40a tightened through the rectangular bag 20 and the plurality of holding bands 30 has a sharp shape holding performance even if the holding band 30 is somewhat loosened. Although it does not fall, in order to maintain the shape-retaining effect of the civil engineering structure A, the holding band 30 having finished tightening of the filling material 40 is fixed so as to hold the tightening force of the holding band 30. You may
As a fixing means of the holding band 30, for example, a fixing pin (not shown) is driven into the filling material 40 to fix the holding band 30, or the polymerization portion of the holding band 30 is slid by a known belt fixing tool It is possible to prevent the holding band 30 from being loosened by holding it in an impossible manner.

  In this example, when carrying and moving the manufactured civil engineering structure A, or when installing it on a site where an external force such as wave force or vibration acts repeatedly, the holding band 30 is surely loosened. It can be prevented.
