In the raft 1 according to the first embodiment, as shown in Fig. 1, the construction surface 2 (law surface) faces upward from the river 3 side toward the land side (right side in Fig. 1). It is inclined so as to extend, and the foundation block 4 is provided at the lower end position of the construction surface 2. The construction surface 2 is formed by the surface of the backfill layer 5 which forms a fixed layer thickness in this embodiment, and the backfill layer 5 is a crushed stone and a calcite stone. It is formed by filling the filling stones (filling material) 6 of the back in the state which meshed with each other. The foundation block 4 is arranged so as to extend in the flowing direction of the river water (the right angle to the ground in Fig. 1), and the foundation block 4 is formed at the upper portion on the land side as it flows upward. The inclined surface 4a inclined to the 3) side is formed.

On the construction surface 2, as shown in Fig. 1, the main purpose is to exert a relief function, and a plurality of civil construction units 7 are laid out on the front surface. Each civil construction unit 7 includes a surface side concrete plate (surface side panel) 8 and a back side concrete plate (back side panel) having a predetermined thickness and having a substantially square plane as shown in FIGS. ), And the surface side concrete plate 8 and the back side concrete plate 9 use the screw rod 10 as a connecting member, so that the plate surfaces of both the 8 and 9 are parallel. It is a configuration having a certain interval while maintaining the state.

The back side concrete plate 9 of each civil construction unit 7 is arrange | positioned on the back filling layer 5 (construction surface 2), respectively, as shown to FIG. Each side of the back side concrete plate 9 is smaller than one side of the surface side concrete plate 8, and the plate surface area (inner and outer surface areas) of the back side concrete plate 9 is surface side concrete. It is smaller than the plate surface area (inner and outer surface area) of the board 8. As shown in FIG. In addition, the side surface 9a of the back side concrete board 9 in each civil construction unit 7 is inclined so that it may extend to the outer periphery as it goes inward from the thickness direction outward, and a back side concrete board The area of the inner surface of the plate surface of (9) is larger than the area of the outer surface of the plate surface. In this embodiment, as this back side concrete board 9, the thing about 70 mm in thickness, and about one side 950 mm is used, for example. Furthermore, as shown in Figs. 5 and 6, the insertion holes 11 are formed in the four corner directions, respectively, on the inner surface of the back side concrete plate 9. Each of the insertion holes 11 allows the back side concrete plate 9 to penetrate in the thickness direction, and on the outer surface side thereof, the diameter of the insertion hole 11 is widened, and a stepped hole 12 is formed. It is.

As shown in FIGS. 1 to 5, the surface-side concrete plate 8 of each civil structural unit 7 is fixed by a predetermined distance with respect to the surface-side concrete plate 9 of each civil structural unit 7. It is located on the upper side. The side surface 8a of this surface side concrete board 8 is formed in the perpendicular | vertical state with respect to the inner and outer surfaces, and the thickness is set so that it may become thicker than the thickness of the back side concrete board 9. The thickness of this surface side concrete board 8 is set so that it may become independent when the side surface 8a is made into the contact surface with respect to the mounting surface, and this Example In the above, the civil engineering construction unit 7 is set so as to sit on the inclined surface of the foundation block 4 set to correspond to steep slopes (for example, 1: 0.3 to 1: 0.6) due to the surface-side concrete. On the side surface 8a of this surface side concrete board 8, a pair of protrusions 13 protrude from the side surface 8aa, and the side surface 8ab facing the one side surface 8aa. The recessed part 14 is formed. The pair of protrusions 13 are arranged at a predetermined interval apart, and the recess 14 is set so as to fit the pair of protrusions 13 of the other civil construction unit 7 therein. . In this case, the recessed part 14 is opened not only in the side outer side of the surface side concrete board 8 but also in the inner surface outer side (refer FIG. 5). In this way, when the side surfaces of the surface-side concrete plate 8 are aligned with each other, the units 7 for civil construction adjacent to each other are not only close to the lateral direction but also close to each other by being lowered from the upper side. A recess of the surface-side concrete plate 8 in the other civil construction unit 7 with a pair of protrusions 13 of the surface-side concrete plate 8 in one civil construction unit 7 14) can be fitted, and positioning of the civil construction units 7 is performed on the basis of the coupling relationship between the recess 14 and the pair of protrusions 13.

On the surface of the surface-side concrete plate 8, a plurality of natural stones 15 are grafted, and small pebbles having a diameter smaller than about 10 mm in the remaining portions other than the natural stones 15 are present ( 16) is kept to cover the remainder (formation of small gravel). The plurality of natural stones 15 and the small gravel 16 are held using the state that the surface-side concrete plate 8 is not hardened, and the plurality of natural stones 15 and the small gravel 16 are civil engineering structures. It performs a function of harmonizing the unit 7 to the natural landscape, the natural stone 15 is to perform a protective function to further protect by preventing external forces such as stone. On the other hand, four insertion nuts 17 are embedded in the inner surface of the surface-side concrete plate 8 corresponding to the four insertion holes 11 as shown in Figs. 5 and 6. These four insertion nuts 17 are arranged inside four corners of the inner surface side of the surface-side concrete plate 8, and the screw holes of the respective insertion nuts 17 are formed on the inner surface of the surface-side concrete plate 8. Facing outwards. In this embodiment, about 130 mm in thickness, and about 1000 mm in one side are used as the surface side concrete board 8.

In the present embodiment, four screw rods 10 are used as shown in Figs. One end of each threaded rod 10 is screwed into the insertion nut 17 of the surface-side concrete plate 8, and at one end thereof, a nut 18 screwed into the threaded rod 10 is provided. It is tightened so that it may strongly contact the inner surface of the surface side concrete board 8. The other end of each of the threaded rods 10 is inserted into the insertion hole 11 of the back side concrete plate 9 by a pair of nuts 19 and 20 screwed to the threaded rods 10. A rear panel (a periphery of the insertion hole 11) is fitted and engaged. At this time, one nut 20 is accommodated in the stepping hole 12, and the other end of the nut 20 and the screw rod 10 screwed to the nut 20 is the rear concrete plate 9. It does not protrude from the outer surface. As a result, the surface-side concrete plate 8 and the rear-side concrete plate 9 are parallel to each other at predetermined intervals by adjusting the nuts 19, 20, etc., and at the same time, the back-side concrete plate While the plate 9 is directed into the inner surface side region of the surface side concrete plate 8, it is arranged concentrically with respect to the surface side concrete plate 8.

Each civil construction unit 7 is stacked on the backfill layer 5 sequentially from the base block 4, as shown in FIG. 1, in relation to the neighboring civil construction unit 7 adjacent to each other. Each side surface 8a of the surface side concrete board 8 abuts. However, the side surfaces 9a of the back side concrete plate 9 in the adjacent civil engineering structure units 7 form a gap 21 between the two 9, 9, and the gaps therebetween. The backfill layer 5 is directed to the space between the surface-side concrete plate 8 and the rear-side concrete plate 9 through 21.

A concrete layer 22 is interposed between the surface-side concrete plate 8 and the rear-side concrete plate 9 of the stacked civil construction unit 7. The concrete layer 22 restricts the back side concrete plate 9 from moving to the surface side (river 3 side), and the surface side concrete plate 8 connected to the back side concrete plate 9 is It regulates the movement to the surface side (falling off). As a result, the concrete layer 22 prevents the surface-side concrete plate 8 from falling off on the surface side, and is integrated with the surface-side concrete plate 8 and the back-side concrete plate 9 to form a construction surface ( The protective wall 23 which engages with 2) is formed (installation of a protective wall).

As shown in FIG. 1, a part of the concrete layer 22 enters the backfill layer 5 through the gaps 21 (indicated by arrows). A part of this entered concrete layer 22 engages the filling stones 6 of the interlocked crushed stones in the back filling layer 5, which is the filling material 6 of the crushed stones in the back filling layer 5. In connection with it, it contributed to the integration of the protective wall 23 with respect to the backfill layer 5. For this reason, in this arc 1, when it is based on satisfy | filling predetermined installation strength with respect to the installation strength of the protective wall 23 with respect to the backfill layer 5 (construction surface 2), a concrete layer When the thickness (weight) of the 22 can be reduced, and the thickness (weight) of the concrete layer 22 is conventional, the installation strength of the protective wall 23 to the backfill layer 5 can be further increased. do.

Further, based on the gaps 21, a part of the concrete layer 22 is formed on the side surface (inclined surface) of the back side concrete plate 9 in the units 7 for civil construction as shown in FIG. Are engaged. For this reason, even if a force in the direction of dropping between the concrete layer 22 and each back side concrete plate 9 in each civil construction unit 7 acts, it is regulated, and each civil construction unit 7 The weight of the concrete plate 9 on the back side is used reliably as the weight for the protective wall 23 to be bonded to the construction surface 2 (increasing the installation strength of the protective wall 23 to the backfill layer 5). Contribution to things).

Next, the construction method of the raft (civil engineering structure) 1 of the gently curved arrangement shown in FIG. 1 is demonstrated.

First, as shown in FIG. 7, the substantially horizontal base surface 24 and the inclined base surface 25 which incline to the land side as it goes upward from the base surface 24 are formed, and the base surface 24 is formed. The base block 4 is formed in a state in which it is somewhat spaced apart from the inclined base surface 25.

Next, as shown in FIG. 8, on the inclined base surface 25, the backfill layer 5 whose surface is the construction surface 2 is formed. The backfill layer 5 is of a constant thickness in the state in which the fill stones 6 such as crushed stone and a chalcedony are interlocked with each other. Is being installed on. The formation of this backfill layer 5 uses a separate method (to be described later) to reduce the work load in the case of a gently curved arrangement of the revetment 1 to be constructed.

Next, the civil construction unit 7 is conveyed onto the back filling layer 5 with a lifting carrier 27 interposed by a crane (using the same reference numeral as the wire 26). As shown in Fig. 9, the civil construction unit 7 is suspended and conveyed due to the inclined state of the surface of the backfill layer 5, and the civil construction unit 7 is in the inclined state. It is lowered on the surface of the inclined backfill layer 5. For this reason, in the suspension conveyance of this civil construction unit 7, the suspension conveyance opening 27 which can adjust the suspension state (inclined state) of the civil construction unit 7 is used.

Specifically, the hanging carrier port 27 is used in the present embodiment, which is schematically configured by the lower arm 28, the upper arm 29, and the connecting portion 30. The lower arm 28 arranges a pair of straight frames (L-angles) 31 apart by a predetermined interval (shorter than one side of the surface-side concrete plate 8) and is disposed at the same time. The reinforcement frame 32 is interposed between the frames 31, and the extension length is somewhat shorter than the length of one side of the surface-side concrete plate 8. The upper arm 29 is arranged in the upper direction of the lower arm 28, similarly to the lower arm 28, with a pair of straight frames (L-angles) 33 extending at predetermined intervals. At the same time, the reinforcing frame 34 extends between the pair of frames 33, and the extension length thereof is shorter than that of the lower arm 28. The connection part 30 is provided with a pair of vertical frames 35 so that one of the vertical frames 35 has a base end of one frame 31 of the lower arm 28 and one frame of the upper arm 29 ( 33 is connected to the proximal end, and the other vertical frame 35 connects the proximal end of the other frame 31 of the lower arm 28 and the proximal end of the other frame 33 of the upper arm 29. . As a result, the lower arm 28 and the upper arm 29 face each other with an interval somewhat longer than the thickness of the surface-side concrete plate 8 (thickness including the natural stone 15).

In addition, as shown in Fig. 9, the upper arm 29 (a pair of frames) is provided with a bolt 36 as a pressing hole in a screwed state, and a plurality of connection holes 37 are formed. The tip of the bolt 36 is directed from the upper arm 29 to the lower arm 28, and the gap between the tip of the bolt 36 and the lower arm 28 is adjusted by turning the bolt 36. It is possible. The plurality of connecting holes 37 are arranged at regular intervals from the distal end of the upper arm 29 toward the proximal end. The wire 26 extending from a crane (not shown) can be connected to the connection hole 37 which is one of the plurality of connection holes 37, and the wire (a) is connected to any one of the connection holes 37. When 26 is connected and the wire 26 is suspended, the civil construction unit 7 is suspended as an inclined state along the connection hole 37. On the other hand, two locking portions 38 are formed on the lower arm 28 (each frame) (see Fig. 9). Each of the engaging portions 38 is formed by cutting the lower arm 28, and the engaging rods 38 are held by the screw rods 10 of the civil engineering construction unit 7. It is supposed to be.

When suspending the unit 7 for civil construction using this suspension conveyance port 27, first, the lower arm is completed on the inner surface side of the surface-side concrete plate 8 in the unit 7 for civil construction to be suspended. While arranging 28, the upper arm 29 is arrange | positioned at the surface side of the surface side concrete board 8. As shown in FIG. Next, the screw rod 10 is fastened to the engaging portion 38 of the lower arm 28, and the bolt 36 is tightened, whereby the front end of the bolt 36 and the lower arm 28 are the surface side. The concrete plate 8 is sandwiched. As a result, the suspension carrier 27 is integrally held by the surface-side concrete plate 8.

Next, the connection hole 37 is selected to make the civil construction unit 7 suitable to the inclined state of the construction surface 2, and the wire 26 extending from the crane side to the connection hole 37 is then selected. When connecting the suspended by the civil construction unit (7), civil construction unit 7 is inclined as a slope suitable for the inclined state of the construction surface (2).

When the civil construction unit 7 is conveyed onto the backfill layer 5 by the above-mentioned lifting conveyance, the civil construction unit 7 is first given the lowest stage first civil construction unit 7A (Fig. In the ninth, a plurality of civil construction units (7) are arranged in the vertical direction of the ground), and are installed on the back filling layer (5). In the installation of the civil engineering structure unit 7, the rear side concrete plate 9 is provided on the construction surface 2, and the side surface of the surface side concrete plate 8 (the side with the recessed portion 14) is present. 8a is arranged to be supported by the inclined surface 4a of the foundation block 4, so that the side face 8a having a pair of projections 13 faces away from the foundation block 4.

Next, as shown in Fig. 11, the concrete 39 is filled in the first stage civil construction unit 7A (between the surface-side concrete plate 8 and the rear-side concrete plate 9). do. By interposing the hardened concrete 40A as part of the concrete layer 22 between the surface-side concrete plate 8 and the back-side concrete plate 9, the movement to the surface side of the back-side concrete plate 9 is regulated. In this way, while the surface-side concrete plate 8 is prevented from falling off, the surface-side concrete plate 8, the back-side concrete plate 9 and the hardened concrete 40A are integrated to form a part of the protective wall 23. Will be.

In this case, the concrete 39 is filled sequentially from the downward direction while using the surface-side concrete plate 8 of the civil construction unit 7 as a frame for the concrete 39, and then the concrete at that time ( The filled upper surface of 39 is from the upper end of the back side concrete plate 9 to a high position which does not overflow. The overflowed concrete 39 does not interfere with the installation of the civil engineering units 7 stacked on the first stage civil engineering units 7A along the backfill layer 5 (second stage). This is to avoid.

At this time, in this embodiment, the concrete 39 is not filled in the entirety of the concrete 39 filling space between the surface-side concrete plate 8 and the rear-side concrete plate 9, and a part of the upper portion is a space. At the same time, the reinforcing bar (not shown) is inserted in the upper end of the filled concrete 39 before its hardening.

Next, as shown in FIG. 12, on the backfill layer 5, the second stage civil construction units 7B (in FIG. 12, a plurality of civil construction units 7 are arranged in the vertical direction of the ground) are placed. The concrete layer having the same shape as the first stage civil engineering unit 7A with respect to the second stage civil construction unit 7B by stacking and arranging it in the first stage civil construction unit 7A. The concrete 39 is filled to form part of the 22. The second stage civil construction unit 7B is related to the arrangement relationship between the surface side concrete plate 8 and the rear side concrete plate 9, and is similar to the case of the first stage civil construction unit 7A. Side surfaces of the surface-side concrete plates 8 in the first-stage civil construction units 7A so that the side surfaces 8a of the surface-side concrete plates 8 are sequentially laid without gaps. (Upper side) Abutting on 8a. On the other hand, in the civil construction units 7A and 7B, the back side concrete plate 9 is generally smaller than the surface side concrete plate 8, and thus the first stage civil construction unit 7A. Between the back side concrete plate 9 and the back side concrete plate 9 at the second stage of the civil construction unit 7B, and further, the civil construction units 7A and 7B adjacent to each other at each stage. A gap 21 is formed between the rear concrete plate 9, and a space between the surface-side concrete plate 8 and the rear-side concrete plate 9 is formed by the backfill layer 5 through the gap 21. You will be directed to. The filling of concrete 39 in the second stage civil engineering unit 7B is performed in the same manner as in the case of filling the concrete 39 in the first stage civil construction unit 7A. Upon filling 39, a portion of the concrete 39 enters the backfill layer 5 through the gap 21. For this reason, when this concrete 39 hardens | cures and becomes hardened concrete 40B, a part of the hardened concrete 40B engages with the filling stones 6 engaged with each other in the backfill layer 5, The engagement relationship Therefore, the protective wall 23 (the civil engineering structures 7A and 7B and the concrete layer 22) is integrated with the backfill layer 5.

In this case, each back side concrete plate 9 is completely surrounded by the concrete 39 except for the outer surface thereof, and after curing of the concrete 39, the side surface (inner surface of the back side concrete plate 9). 9a of inclined surfaces extending outwards to the side and its hardened concrete 40A, 40B are engaged, so that each back side concrete plate 9 is separated from the hardened concrete 40A, 40 by Moving to the country is regulated. For this reason, each back side concrete board 9 can be reliably integrated with the hardened concrete 40A, 40B (falling prevention), and the weight of the surface side concrete board 8 and the hardened concrete 40A, 40B is prevented. In addition, the weight of each back side concrete plate 9 can be reliably used to increase the installation strength.

In this case, moreover, the concrete 39 remains in the first stage civil engineering unit 7A by the filling of the concrete 39 in the second stage civil construction unit 7B. At the same time as the filling space 41 enters, the reinforcing bars embedded in the concrete 39 in the first stage civil engineering structures are embedded. Therefore, between the hardened concrete 40A formed in the second stage civil construction unit 7B and the first stage civil construction unit 7A (surface side concrete plate 8, rear side concrete plate 9) At the same time, the hardened concrete 40A and 40B formed in the civil engineering structures 7A and 7B in the first and second stages are also integrated by reinforcing bars, thereby forming a protective wall 23 (protective wall 23 as a whole). A part of) will have sufficient integration strength.

In this way, the stacking of the civil engineering construction unit 7 and the filling of the concrete 39 are sequentially repeated, and finally, the lower part of the foundation block 4 and the protective wall 23 is filled, thereby providing a revetment 1 shown in FIG. ). Therefore, in this heading 1, each civil construction unit 7 (surface side concrete plate 8, back side concrete plate 9), and concrete layer 22 (each civil construction unit 7) Not only the protective walls 23 are formed on the backfill layer 5 by the hardened concrete 40A, 40B, ..., but also a part of the concrete layer 22 is backfilled through each gap 21. It enters (5), engages with the filling stone 6 in the back filling layer 5, and the installation strength of the protective wall 23 with respect to the back filling layer 5 becomes high.

13 shows a second embodiment, and FIG. 14 shows a third embodiment. In each of these embodiments, the same components as those of the above embodiment are denoted by the same reference numerals and the description thereof will be omitted.

2nd Embodiment shown in FIG. 13 has shown the content which reduces the workload which forms the backfill layer 5, when building the bank of steep inclination. In the case of constructing a steep slope, a backfill layer 5 is not formed on the inclined base surface 25, and the civil construction unit 7 is first formed on the inclined surface 4a of the foundation block 4. Free standing as the surface side concrete board 8. That is, at this time, the inclined base surface 25 is steeply inclined, while the inclination angle of the inclined surface 4a of the foundation block 4 becomes smooth with respect to the horizontal direction, so that in the civil construction unit 7 By attaching the side surface 8a of the surface side concrete plate 8 and the side surface of the back side concrete plate 9 to the inclined surface 4a of the foundation block 4, the said civil engineering structure unit 7 becomes independent. . As a result, the back side concrete plate 9 functions as a partition plate forming the filling space 42 of the filling stone 6 which is spaced apart from the inclined base surface 25 by a predetermined interval. When the filling stone 6 is filled in the filling space 42 formed by the plate 9 and the sloped base surface 25, a part of the back filling layer 5 is easily formed. In this case, since the base surface 25 is steeply inclined, the filler seats 6 are filled in the state of being engaged with each other on the lower side only by injecting the filler seats 6 based on the steep slopes, and the firm backfill layer 5 Is formed.

In the first stage civil construction unit 7A, when the filling of the filling stone 6 and the above-described concrete 39 are finished, the second stage civil construction unit 7B is 1 The upper side surface of the stage 7A civil engineering construction unit 7A is abutted, and the upper side surface thereof is a mounting surface, and the second stage civil construction unit 7B freely stands. Also about this 2nd stage civil engineering structure unit 7B, the filling stone 6 is filled and the concrete 39 is filled, and this operation | work is repeated hereafter.

As for the civil engineering structure 7 used in this embodiment, the surface side concrete board 8 and the back side concrete board become the same, and the direction orthogonal to the ground with respect to the length of the direction along the slope base surface 25 In the gap, a gap 21 is formed between the concrete plates 8 on the back side of the adjacent civil construction 7. In the case of 5-part slant (5 minute inclination), such a civil construction unit 7 uses a surface side concrete plate 8 having a thickness of 130 mm, a length of 1250 mm, and a width of 800 mm. It is preferable to use the one having a thickness of 70 mm as the side concrete plate 9.
