Description

[Detailed Description of the Invention] (1) Technical Field The present invention relates to a structure for a ridge that partitions rice fields and a method for implementing a ridge road.

(2) Conventional technology Conventionally, the ridges separating rice fields were made by mounding the soil high and hardening it. This work of raising the soil high and hardening it requires a lot of labor and time. In addition, the banks built by mounding up soil would collapse over time, requiring effort to repair each time. Moreover, there was a risk of water flowing out from this collapsed area, and there was also a risk of water seeping into the earthen ridge and causing a leak.

Therefore, in order to solve these drawbacks, it was thought that the levees could be made of concrete. Figure 1~
Figure 7 shows the construction process for a conventional concrete embankment. First, a hole 50 is excavated in a place that will become a footpath, and stones 52 are buried in the bottom 51 of this hole 50.
The bottom portion 51 is rolled from above (FIGS. 1 and 2).
Next, concrete 53 is poured horizontally into the bottom 51 of the hole 50, and after it hardens, two formworks 54 are assembled and installed on top of the concrete 53 by measuring a certain distance and ensuring parallelism. (Figures 3 and 4). Then, concrete 55 is poured into this formwork 54, and concrete 55 is poured into the formwork 54.
After solidification, remove the formwork 54 (Figs. 5 and 6).
figure). The formwork 54 is either discarded or saved for the next time, and finally, as shown in FIG. do. The concrete embankment was created through the above process.

However, such conventional concrete ridges,
Unlike a ridge made of earth, it does not collapse, so it is possible to prevent water from flowing out or leaking.However, after pouring concrete 53 onto the bottom 51 of the excavated hole 50 and compacting the ground, formwork 54 is prepared. This requires a lot of effort and time. Furthermore, it is technically difficult for a farmer to carry out a series of these tasks on his own, and there is a drawback in that a specialist engineer must be entrusted to carry out this series of operations.

(3) Purpose Therefore, the purpose of this invention is to provide a construction method for a bank structure and a bank road that can be easily made by a farmer without requiring labor and time and without requesting a specialist. do.

(4) Configuration The present invention will be explained below based on the drawings.

FIGS. 8 to 14 show an embodiment of a structure for a levee according to the present invention, in which 1 is a rectangular flat plate, with a slope 1a formed at the upper end, and a slope 1a on the slope 1a. Wires 1b are buried at appropriate intervals with some parts protruding. Further, 2 is a fixed block that is approximately trapezoidal or has a stone setting 2c protruding from one side, and has a groove 2a opening at the center of its upper side. One surface of each flat plate 1 is in contact with the groove vertical wall 2b of the groove 2a provided in the fixed block 2, and each flat plate 1 is erected with the sides on which the slope 1a is formed facing each other, and the mating surface 1 with the adjacent flat plate 1
c is provided at a shifted position with respect to the opposing flat plate 1. These flat plate 1 and fixing block 2 are standardized, manufactured in a factory, and sold commercially. As shown in FIG.
A plurality of them are arranged in a row and placed in hole 4. A bonding agent 3 is filled between these opposing flat plates 1, and the bonding agent 3 connects the opposing flat plates 1 and fixing block 2. As the bonding agent 3, for example, cement, mortar using cement, or concrete is used. Furthermore, the tips of the wires 1b protruding from the slope 1a are tied to each other between the opposing flat plates 1 to prevent the flat plates 1 from falling outward and to reinforce the joint between the opposing flat plates 1. . In addition, it is also possible to provide a spacer (not shown) between the flat plates 1 instead of the wire 1b to prevent the flat plates 1 from falling outward. Moreover, as shown in FIG. 14, the capstone 1d has a conical cross section,
The groove 1e has a width comparable to the thickness when the two flat plates 1 are brought into close contact with each other, and the length in the direction perpendicular to the plane of the paper in FIG. 14 may be such that it covers only the vicinity of the connection position of the two flat plates 1 Alternatively, the length may be such that it completely covers the upper end surfaces of the two flat plates 1.

Next, the road enforcement method according to the present invention will be explained. FIG. 15 to FIG. 18 show the process of constructing a concrete embankment according to the present invention. First, a hole 4 is excavated in a place that will become a road, stones 6 are buried in the bottom 5 of this hole 4, and the bottom 5 is compacted from above (FIGS. 15 and 16). Next, the fixing blocks 2 are placed at the bottom 5 of the hole 4 with appropriate intervals and the grooves 2a are aligned, and the grooves 2 provided in the fixing block 2 are
The back surfaces of the flat plates 1 with the sides provided with the slopes 1a facing each other are brought into contact with the vertical groove wall 2b of the groove part 2b, and are erected. Next, a bonding agent 3 is injected between the facing flat plates 1 and around the fixing block 2 to join the facing flat plates 1 and the fixing block 2, and fixing the fixing block 2 in the hole 4 (FIG. 17). Then, the hole 4 is backfilled with soil 7 to completely bury the fixed block 2 and to make a part of the flat plate 1 protrude above the ground (FIG. 18).

As for the filling method, as shown in FIG. 12, the bonding agent 3 may be filled between the flat plates 1 at regular intervals so as to form a rectangular parallelepiped, or if the bonding agent 3 is simply to be partitioned, it may be filled as shown in FIG. 13. It may be filled only between the slopes 1a formed at the upper end portions of the flat plate 1 which are in contact with the opposing side surfaces thereof. Furthermore, as shown in FIG. 14, the capstone 1d may be placed on the flat plate 1 without being filled with the bonding agent 3, and the two flat plates 1 may be fitted and joined together.

(5) Effects As explained above, according to the present invention, flat plates or fixed blocks are standardized and commercially available, so that amateurs such as farmers can easily install roads along roads without asking experts. Moreover, since there is no need for formwork etc., costs can be saved. In addition, compared to conventional concrete berms, they can be made easily, reducing labor and time. Furthermore, as shown in Figures 13 and 14, a levee made by abutting the sides of opposing flat plates and filling only the upper end slope with a bonding agent, or by fitting a capstone onto the flat plate, will allow for future movement of the levee. It can be easily disassembled when necessary, and it can be easily assembled at a moving location on the bank.
