[Prior Art] Japanese hydroponics has long been a long road,
That is, the ridge has been set up. The purpose of this is to divide the paddy field into compartments, to store water necessary for growing rice, and to secure a path for people to walk. However, this ridge was made by collecting the cultivated soil of the paddy field and simply filling it in a trapezoidal shape. Therefore, it was originally soft and deformed or collapsed every time a person walked or was hit by heavy rain. In cold regions where temperatures below freezing continue for a long time in winter, natural collapse even occurred in early spring when the frozen soil on the ridge melts. The work of repairing such deformations and collapses is repeated every year, and since the ridge has a long distance, the effort required for it is not stupid, and if it is left as it is, the original shape may not be retained. It has collapsed to the point where a big job of re-building the embankment is waiting.

By the way, the conventional ridges made only by embankment pose various problems other than this.

1. The ridges are originally soft and are constructed using cultivated soil from paddy fields that contain a large amount of water, and the lower part of the ridges are constantly immersed in water during the season, which makes them extremely deformable. is there. Therefore, as described above, due to the walking of people and heavy rain, and in addition to the action when the freezing is loosened in cold regions, deformation and collapse easily occur. Moreover, the unevenness on the upper surface of the ridge makes it very difficult to walk along the ridge. Therefore, as an old wisdom, 4 on the slope of the ridge
It is generally recommended that the inclination angle be about 5 degrees.
However, this is effective to some extent in terms of preventing natural collapse, but does not completely prevent deformation and collapse due to walking.

[0005] 2. The next troublesome issue is the spread of weeds. It is a phenomenon that it always follows as long as the ridge is exposed as soil, but the specific problems caused by this weed can be divided into the following three. a. When weeds grow to some extent, it becomes difficult to walk on the ridge, and if there are weeds with high height, it becomes impossible to walk,
In some cases, it may even create an unfavorable shade for growing rice. Therefore, it is necessary to clean up the weeds manually or with a mower. Otherwise, it requires a herbicide and therefore the effort of spreading the herbicide. In any case, you will be forced into labor and expense. b. Moreover, the infestation of weeds promotes the development of pests. For example, C. elegans becomes an adult C. elegans moth around July, and eventually lays eggs on the leaves of rice. Then, this egg becomes a new larva called a dimorphic worm, which enters the stem of the growing rice and eats it, so that the rice is hindered from growing and eventually falls. After that, as a larva, they dive into the weeds on the ridge and over the winter, becoming a moth. In addition, insects such as rice mud-bearing insects and locusts also hatch and grow using the weeds and soil on the ridges, eventually resulting in damage to rice growth and harvest. Therefore, the conventional ridge is also a hotbed for insects harmful to rice. c. Next is the damage of the rat. In the winter when food is scarce, wild rats make holes here and there on the ridges and survive by eating the roots of weeds that appear in the holes. In this way, the mouse formula increases, and in the late summer when the paddy fields are drained and the final stage of rice cultivation is reached, this time the rice stalks are also eaten up, causing damage. What's worse, these ridge holes made by Noro during the winter when the paddy fields are waterless serve as water channels when the paddy fields are flooded. That is, even if water is drawn to a paddy field, a predetermined water depth cannot be obtained due to water leakage, or unnecessary water is passed from one paddy field to another paddy field and then to another paddy field through these holes. The flow of is generated sequentially. Water will also leak from this hole into the soil under the ridge. Therefore, water is wasted, and if the water stays, the water that should be gradually warmed by the sun's heat will constantly flow into it, and the cold water will not keep up with the temperature of the water, eventually causing cold damage to the rice. The effect of this is a serious problem because cold water inevitably flows into paddy fields such as cold regions. In order to prevent this, it is necessary to look around the ridge in advance, find a hole and repair it as soon as possible. As mentioned above, it is a reality that the embankment, which is still embanked, is also a hotbed for growing rodents that are harmful to rice cultivation.

[0006] 3. Among the soils that make up the ridges, the part under the water contains plenty of water and is particularly weak. Therefore, even if there is no clear hole, the water stretched in the paddy field naturally leaks from the cultivated soil part to the underground through the soil at the bottom of the ridge, so it is necessary to supply water for that purpose. Therefore, the same adverse effect as described in the item 2-c above occurs.

From the above description, it is understood that the conventional method of embankment, which is simply embankment, has many defects. However, none of these drawbacks have been solved yet, and at the present, the following exist at most.

[0008] 1. It is a flat plate or corrugated plate made of plastic. Most of this is about 25 cm wide,
It is often used because it is cheap. However, the purpose of using this is to take measures against only the above three items. That is, water is prevented from leaking underground through the soft cultivated soil below the surface of the water and the soil below the ridge. Therefore, this plastic plate is laid along the side of the ridge, and its lower end is inserted into the hoe floor located under the cultivated soil in the paddy field, and the water impermeability of the hoe floor is used to prevent water leakage. Is what you do. However, in this case, most of the ridges are still exposed, so they are useless for other purposes, and at the same time,
When cutting a grass, the upper part of the plastic plate is scraped off by the mower, which damages the mower, and it looks awkward and cracks. Moreover, when it is grilled, it becomes black and shrinks or becomes unusable. Therefore, it is also a kind of consumable item.

2. Concrete boards are more durable and permanent than the above plastic boards. This is a rectangular plate, but the short sides are set up side by side to form a long strip. The purpose and the point that the lower end of the digging into the hoe floor to prevent water leakage by utilizing the impermeability of the hoe floor to water are the same as in the case of 1. It's good that this one is more durable and permanent, but after all, most of the ridges are still exposed, so we need to mow them,
If you do it badly, the blade of the mower will be seriously damaged, and there is a risk that it may cause serious injury to humans.

3. Next, there is a cultivated soil tractor with attached machinery. This is not useful for prevention in advance, but it is for symptomatic treatment of repairing the ridge and is called a ridge coater. In this way, the soil taken from the paddy fields is applied to the ridge, and the shape of the ridge is adjusted while repairing the deformed or collapsed ridge and the holes. Therefore, this machine does not improve the conventional ridges at all, but rather even requires them to be conventional ridges. Moreover, it is not possible to avoid the need to repeat this work every year, and it is also necessary to purchase expensive accessory machines, which cost about 400,000 yen as of 1992.

[Problems to be Solved by the Invention] In recent years, several proposals have been made as semi-permanent measures against the above-mentioned conventional techniques. For example, Japanese Utility Model Laid-Open No. 62-129433 is known. The feature of this known technique is that "a cover plate having a key-shaped cross section and a connecting portion is of a socket type, and the present ridge is shaped and covered and connected to construct". However, with this key, it expands when the ridges freeze in winter,
The problem remains that the tip corners and sockets that form the keys are cracked or damaged. Further, when a cavity is formed inside the key cover plate and repair is performed, there is a drawback in that the work of embankment on the ridge is redone and a large installation work is performed.
In addition, Japanese Utility Model Publication No. 62-20508 published prior to the filing of the present application discloses "a road shoulder covering in which a side plate portion is extended to a long side edge of a rectangular flat plate portion through a flexible curved portion". However, the side plate is steep and almost vertical,
There is a problem that the road shoulder inside it begins to collapse after a certain period of time, and if it becomes a cavity above a certain level, the road shoulder equipment itself collapses toward the mud side in the paddy field. The present invention is intended to solve these problems and problems, and is to devise a device that can easily cope with changes in winter freezing and spring dissolution of ridge soil especially in cold regions.

In the following description, the "ridge cover plate" will be simply referred to as the "cover plate". 1. The action exhibited by the coating plate according to claim 1 used in Examples 1 to 8. The appearance of the action of the covering plate (1) having this shape will be described separately for the case where it is used only on one side of the ridge and the case where it is used for both sides. In this case, it is naturally assumed that the ridge has already been shaped to have the same shape as the inner surface of the side surface of the covering plate (1). A. The case of using on one side of the ridge will be described with reference to FIGS. 2 and 3. I. The horizontal plane portion (P) is placed horizontally on the upper surface of the ridge, which is flat and horizontal, so that the lower end (a) of the covering plate (1) reaches into the hoe floor (5A). At this time, the vertical surface portion (V) automatically becomes vertical. B. At this time, since the upper part of the ridge soil (2) is trapezoidal, it is stable, and exhibits an effect of not causing the ridge deformation when the covering plate (1) is installed. C. Due to the weight of the covering plate (1) itself, the horizontal surface portion (P) and the sloped surface portion (S) are constantly in close contact with the upper surface of the ridge while pressing it downwards, so that the ridge is more closely attached and stable. It also acts to prevent the risk that the lower end (a) of the vertical surface (V) will sink deep into the soil if left alone. D. At the place where the covering plate (1) is installed, the covering plate (1) covers the ridge soil (2), and is in strong contact with the ground plate (5A). Therefore, the ridges will not be deformed or collapsed, weeds will not grow, field mice will not be able to dig holes,
It does not cause water leakage and appears as an action. The lower end (a) of the vertical surface portion (V) embedded therein is hard to move, while the side end (b) of the horizontal surface portion (P) has a degree of freedom to move, and at the same time, the covering plate (1). Its own weight is a
It will appear as a strong moment that attempts to lower the point b with the point as the fulcrum. In other words, the covering plate (1) itself in FIG. 2 has an effect of constantly falling toward the lower right direction, and at this time, the inclined surface portion (S) and the horizontal surface portion (P) inclined at about 45 degrees are It appears as a function of pressing the upper surface of the ridge more strongly and firmly adhering the upper surface of the ridge and the road shoulder. Therefore, even if no measures are taken to fix the covering plate (1) to the ridge, it will never fall to the paddy field side due to an earthquake or the like. The angle of the inclined surface portion (S) may be as shown in the figure, as long as the natural collapse angle of the ridge soil is about 45 degrees. F. Further remarkable effects are exhibited when used in cold regions where sub-zero temperatures continue for a long time in winter. That is, when the ridges that have turned into frozen soil are melted with the arrival of spring, the ridges are naturally deformed and collapsed, which can be prevented by using this cover plate (1). This is the normal state of Fig. 2, but especially in the upper part of the ridge soil during winter.
When the depth of about 0 cm becomes frozen soil, it becomes extremely hard and expands at the same time, and this expansion expands the coating plate (1).
Is deformed by pushing as shown in FIG. If there is no covering plate (1), as shown on the right side of Fig. 3, the ridges may be deformed due to the holes dug in the rodents, the melting of frozen soil accompanying the rise in temperature, the weight of snow, and small avalanches. The collapse is unavoidable.
However, even if the ridge becomes frozen soil, the covering plate (1) tilts according to the expansion of the frozen soil while keeping its inner surface in close contact with the frozen soil. Moreover, if the frozen soil loosens, the moment that tries to make a return to the current state is constantly moving while coming into contact with the frozen soil and responding to the looseness of the frozen soil, so the ridgeline soil (2) does not break and the current state is restored by itself. The action to fulfill is coming out. It is even the result that the weight of the snow deposited on the covering plate (1) plays a role in making this moment stronger. B. When used on both sides of the ridge This may be used as shown in FIG. 4 or as shown in FIG. In both cases, the gist of the items A to E of the above A can be applied as they are, and thus the duplicated description is omitted here. In the case of FIG. 6, the description of the above item will be omitted because it can be easily understood by applying the description of the above item to both sides. For FIG. 4,
Except for the point that both coating plates (1A, 1B) are tilted as shown in FIG. 5, the procedure is the same as the above-mentioned item (f), and can be easily understood without any particular explanation. Therefore, redundant description regarding this is omitted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Specific embodiments of the present invention will be described below with reference to the drawings. Since there are some points to be noted in the implementation, these will be listed first. a. It is desirable that the construction described in the following examples is not carried out when there is water in the paddy field, but during the agricultural closing period from autumn when there is no water in the paddy field until spring of the following year. b. In the examples of the present application, it is explained that the covering plates (1, 1A, 1B) are made of concrete.
In this case, inside the coating plate (1, 1A, 1B),
It is desirable that a reinforcing rod or a thick wire mesh is arranged and subjected to a durable processing. However, this is because concrete has generality in terms of cost. c. Regarding the thickness and length of the coating plates (1, 1A, 1B), take into consideration that the necessary strength can be obtained sufficiently and that the weight can be sufficiently transported and constructed by one or two people. It is desirable to be decided. d. Inside the covering plate (1, 1A, 1B) ridge (2)
It may have unevenness for stronger contact with the outer surface or unevenness for preventing slippage on the outside. In this case, there is a difference in the shape between the side surface of the covering plate and its cross section in the longitudinal direction. In the claims, "... has a cross-sectional shape basically the same as the side surface thereof" means that this case is also included. e. Horizontal planes (P, P1, P2) and vertical planes (V, V
1, V2) and the slopes (S, S1, S2) width and inclination angle are preferably determined according to the actual conditions of the ridge in each paddy field. In this example, the effect was remarkable in the range of 40 to 50 degrees as illustrated. However, the horizontal plane (P) and the vertical plane (V, V1,
The positional relationship with V2) is 90 degrees in angular position. However, this 90 degree does not mean that a minute difference does not allow 90 degrees, and there is no problem even if there is a slight difference in angle. The point is that when the horizontal plane is horizontal, the vertical plane is vertical or vertical. That's fine if it's close. f. The lower end (a, c) of the covering plate may be rounded or sharpened.

In the construction of the following examples, it is necessary to modify the ridge soil (2) to a shape that fits the inner shape of the covering plate (1, 1A, 1B). (2) is extremely soft, so use a scoop,
It can be easily carried out by using an iron plate bent into this shape, and it does not require that the shape be adjusted so strictly. By the way, when explaining the following embodiments, it is necessary to re-recognize how the paddy fields are constructed for reference. This can be seen in the paddy field (3
A, 3B) is surrounded by ridge soil (2) made by putting soil collected from the cultivated soil (4A, 4B) of the paddy field, and the paddy field (3A, 3B) itself is soft with a depth of about 15 cm. Consists of cultivated soil with high water content (4A, 4B), hoe bed (5A, 5B) underneath that has a high impermeability to water, and subsoil (6A, 6B) located further below During the rice planting season, water (7A, 7B) is stretched to a depth of several cm to ten and several cm.

[Embodiment 1] As shown in FIG. 4, this is a case in which the upper surface and the three side surfaces of the ridge soil (2) are covered, and especially in the case of adjacent paddy fields (3A, 3B). This is an embodiment in the case where there is no difference in height, and a covering plate (1B) having the same specifications as the covering plate (1A).
And are arranged so that their plane portions (P1, P2) overlap each other. I. While pressing the vertical surface portion (V1) of the covering plate (1A) against the vertical surface of the ridge soil (2), the lower end (a) of the covering plate (1A) was embedded into the hoe floor (5A), and the covering plate (1A) The horizontal surface portion (P1) is placed horizontally on the flattened upper surface of the ridge soil (2). B. Using the covering plate (1B) having the same specifications as the covering plate (1A), the lower end (c) of the covering plate (1B) is pressed against the vertical surface (V2) of the covering plate (2B) against the vertical surface of the ridge (2). ), And the horizontal plane part (P2) of the covering plate (1B) is placed in a state of being superposed on the upper surface of the horizontal plane part (P1) of the covering plate (1A). At this time, a difference in height between points a and c occurs only by the thickness of the covering plate (1B), but both of them are sufficiently embedded in the hoe beds (5A, 5B) respectively, so underground leakage There is no inconvenience to the measures.
It should be understood that if the covering plate (1A) is rotated 180 degrees on the horizontal plane and the front and back are reversed, the same thing will be the shape of the covering plate (1B). C. By repeating the above steps a and b, the covering plates (1A) and the covering plates (1B) are arranged so as to be continuous without a gap, and the work is performed over the entire length of the ridge. At this time, a method may be adopted in which the covering plate (1A) located on the lower side of the combination is first arranged and constructed over the entire length of the ridge, and then the covering plate (1B) is arranged and constructed. When there is only one person, this construction method is more efficient because there is no need to move to both sides of the ridge. In addition, at the time of this construction, using a thick agricultural vinyl sheet at the joint part of the covering plate (1A), put it on the upper surface of the ridge soil (2), and then if construction is carried out, rainwater will penetrate and weeds. If it is a balloon, it can be sufficiently prevented. The above
By the procedure of c, the construction of the part where the ridge is straight is completed. D. At four corners of the paddy field where the ridges intersect at right angles, as shown in Fig. 12, the covering plate (1A, 1
In (B), a portion (Q) that cannot cover the ridge is generated. However, if the area of the ridge of this part is extremely small, as a countermeasure against this, it may be covered with a commercially available concrete plate, coated with mortar, or Plate for covering thick vinyl sheets (1A, 1B)
It may be sandwiched between and covered. In addition, coating plates (1A, 1
B) may be cut at an angle of 45 degrees so that it fits like a frame plate of a frame and corresponds to a right-angled portion. This cutting can be easily carried out with a hammer and chisel, with a saw if necessary, or with a concrete cutter. Therefore, it is good to manufacture the products used for the corners as a product, keeping in mind that the absolute demand is small, but even if it is not commercialized, the above measures will be in time. Therefore, by performing the above steps a to d, the covering of the entire ridge is completed. E. In addition, when the ridge is covered, it is necessary to take measures to transfer water to or from the adjacent land. For this, use a hammer and chisel in the water-immersed part of the covering plate (1A, 1B). Just make a hole and insert a pipe into this part as usual. A small gap between the pipe and the covering plate (1A, 1B) can be easily filled with mortar.

[Embodiment 2] As shown in FIG. 6, this is a case in which the upper surface of the ridge soil (2) and the three surfaces of both sides are covered, and especially in adjacent paddy fields (3A, 3B). This is an embodiment in the case where there is no difference in height, and a covering plate (1B) having the same specifications as the covering plate (1A).
And are arranged so that they are in contact with each other at the side ends (b, d) of the plane portions (P1, P2). Assuming that the coating plate used in Example 1 and the coating plate used in Example 2 are applied to the same ridge, the coating plate flat portions (P1, P2) used in Example 2 are assumed. The width of () is about half as narrow as that of the first embodiment. Regarding the order and method of construction in this case, since this is almost the same as I to E described in the first embodiment, only the differences from the first embodiment will be specified here, and the others will be the same as the first embodiment. The description of (a) to (e) is borrowed and replaced with the description. The differences are described below. 1. The item (b) in the first embodiment is modified as follows to become the item (b) in the present embodiment. B. Using the covering plate (1B) having the same specifications as the covering plate (1A), the lower end (c) of the covering plate (1B) is pressed against the vertical surface (V2) of the covering plate (2B) against the vertical surface of the ridge (2). ), And place it so that the side edge (d) of the horizontal plane portion (P2) for the coating plate (1B) contacts the side edge (b) of the horizontal plane portion (P1) for the coating plate (1A). 2. The following items are added to the item c in the first embodiment to form the item c in the present embodiment.

[Embodiment 3] As shown in FIG. 7, this is a case in which the upper surface and the both side surfaces of the ridge soil (2) are covered, and moreover, the adjacent paddy fields (3A, 3B) are small. This is an embodiment in the case where there is a moderate difference in height, and the covering plate (IA) and the covering plate (1B) of inevitably different specifications are arranged so as to overlap at the horizontal portions (P1, P2). This is the case. In the above, we used the term small to medium height difference, but this is difficult to say with a specific height. However, when viewed from the upper surface of the ridge in FIG. 7, this is limited to the extent that it can be easily dropped onto the paddy soil in 3A and can be easily stepped down into the soil in the deeper paddy in 3B. The height up to a slightly lower level is tentatively called "medium", and the level "smaller" is lower than this. In this case, there is a difference in the depth from the upper surface of the ridge between the paddy field (3A) and the paddy field (3B), regardless of the difference in elevation between small and medium. The lengths of the slopes (S1, S2) inevitably differ from those of the covering plate (1B). In this case, the slopes (S1, S2) having the same inclination angle are used. Under the above-mentioned premise, the manner in which the ridge covering work is performed is similar to the items (a) to (e) described in the first embodiment, and therefore, the duplicated description will be omitted here.

[Embodiment 5] As shown in FIG. 9, this is because the adjacent paddy fields (3A,
3B) when the height difference between them is large. In such a case, the ridge separating the adjacent paddy fields (3A, 3B) also has a two-tiered structure, and is usually composed of the ridge soil (2A) and the ridge soil (2B). In this case, the ridge soil (2
Depending on the shapes of A) and the levee soil (2B), the covering plate used may be the same or may have different specifications. However, it is not practical to use the combination as in Example 1 or 2. The reason for this is that if the covering plate covers even the right side slope of the ridge in FIG. 9, the covering plate would have to be extremely huge,
Moreover, it has a complicated shape, is easily broken, and is difficult to carry and construct. Therefore, if it is desired to cover even the right slope of the ridge, it can be said that it is advisable to adopt a construction method such as stretching a concrete plate that is often used for civil engineering work. In this case, either construction may be done first, but in consideration of the possibility that the soil of the ridge soil (2A) may fall onto the ridge soil (2B) during the construction, the covering plate The process when starting from (1A) is as follows. I. Lower end (a) of the vertical surface portion (V1) of the covering plate (1A)
While fully embedding into the hoe floor (5A), the horizontal surface portion (P1) of the covering plate (1A) is placed horizontally on the flattened ridge soil (2A) upper surface. B. A plate for coating (1A) while repeating the procedure of the above b.
The construction is done so that the two are continuous without any gaps, and this is done over the entire length of the ridge. C. By performing the steps similar to the above a and b for the lower ridge, the construction for the upper and lower ridges is completed. Note that, in the case of this embodiment as well, the consideration of the items c to e described in the first embodiment is applied. However, since this embodiment is not a combined use of the covering plates, the matters related to the combination and the shapes of the connection auxiliary plates and the like that naturally change accordingly can be easily modified and interpreted with common sense. Omitted description.

In the above-mentioned Examples 1 to 5, the construction works without any problems when the ridge is in the land owned by the owner or when the agreement with the owner of the adjacent paddy field is obtained. Can be started. However, there are cases where the owner's agreement cannot be obtained for some reason. Even in such a case, by using the covering plate of the present invention, it is possible to carry out construction work on the ridges only on the own side. In addition, the boundary line with the adjacent land in the paddy field is usually located at the center position of the upper surface width of the ridge. The following examples also discuss the consensus.

Next, a sixth embodiment shows an example in which the ridge covering work on the own side is independently performed when the ridge forms a boundary with the adjacent land and the landowner of the adjacent land agrees. . [Example 6] This is the construction method shown in Fig. 2, in which the paddy field on the own side is 3A and the adjacent one is 3B. In the case of this construction, the entire upper surface of the ridge is covered, and therefore the upper surface of the ridge belonging to the adjacent land is also covered. This construction is done at the expense and labor of this side, and because it covers the entire upper surface of the ridge, it is easier to walk, and because it looks beautiful, it is possible to enjoy this benefit free of charge. It is customary for the landowner to complain. Since the construction process in this case is the same as that of the fifth embodiment, which explains the construction of the covering plate (1A) with reference to FIG. 9, duplicated description will be omitted here. Later, if the landowner on the adjacent land wants to cover the ridge, it can be easily constructed by using the combination method as shown in FIG.

[Embodiment 7] However, the landowner in the adjacent land is a stubborn person, and the landlord is 1 from the boundary line.
Fig. 1
The coating plate (1) for one's own side only needs to be installed in the state shown in 0. In this case, the side edge (b) of the covering plate (1) is a boundary line stop, and the width of the plane portion (P) of the covering plate (1) used in this embodiment is as shown in FIG. It is a matter of course not to mention that it is about half of the case. Since the construction process in this case is the same as that of the second embodiment, which explains the construction of the covering plate (1A) with reference to FIG. 6, the redundant description will be omitted. Later, when the owner of the adjacent land also wants to cover the ridge, it can be easily constructed by using the combination method as shown in FIG.

[Embodiment 8] This is an application example of Embodiment 7. That is, in Example 7 using the method shown in FIG. 10, since the covering plate (1) is simply arranged on the upper surface of the ridge, the construction is easy for oneself, and when the landlord of the adjacent land constructs it later. However, it is an easy method, but it is a little difficult to walk because there is a step on the upper surface of the ridge. Therefore, in this embodiment, the upper surface of the ridge up to the boundary line is scraped off by the thickness of the covering plate (1) and then arrayed,
As shown in FIG. 11, the entire upper surface of the ridge is made flat. Side edge (b) of the covering plate (1) in this case
Is a boundary line, and the width of the plane portion (P) of the covering plate (1) used in this embodiment is about half that in FIG. Is a matter of. In the construction process in this case, the construction of the covering plate (1) will be described with reference to FIG. 10 except that the work for cutting the upper surface of the ridge up to the boundary line by the thickness of the covering plate (1) was added. Since it is the same as the seventh embodiment described above, redundant description will be omitted. Later, when the owner of the adjacent land also wants to cover the ridge, the upper surface of the ridge should be scraped off by the thickness of the covering plate (1), and then the combination method as shown in Fig. 6 should be used. It can be easily installed with.

[Effects of the Invention] The present invention exhibits the following effects. 1. There is no deformation or collapse of the ridge caused by a person walking on the upper surface of the ridge, or by stepping on the corner or slope of the ridge. 2. Water that melts rain or snow does not enter the inside of the ridge, making it a strong ridge soil. 3. In cold regions where the levee soil turns into frozen soil, the natural collapse of the ridge soil is eliminated when the frozen soil melts. 4. Weeds no longer grow on the ridge. Therefore, as described in detail below, various harmful effects caused by weeds are eliminated. a.
There is no need to pay the cost and labor for spraying the herbicide, and there is no need to mow the grass. b. Since the occurrence of pests can be suppressed, the cost and labor for spraying pesticides can be reduced, and at the same time, the damage of rice pests can be protected. c. It becomes a deterrent to the breeding of wild rats, because the roots of the weeds that the rodents eat during the winter are lost. d. Water leakage caused by the hole on the ridge cut by the wild rat is eliminated, waste of water can be prevented, and there is no need to replenish water. Further, this makes it possible to prevent cold water from continuously flowing in a cold region, so that it is possible to reduce the influence of future cold damage. 5. Natural leakage in the lower part of the ridge soil can be prevented, and the same effect as 4d above can be obtained. 6. Since the covering plate has a slope part inclined at about 45 degrees, it makes the ridge soil trapezoidal and stabilizes it, and at the same time it escapes from some protruding parts from machines such as cultivated soil tractors. It also prevents damage to the machine. 7. Even if there is another world on the ridge, construction can be done without disturbing the owner of the adjacent land. 8. Even if the owner of the adjacent land wants to construct the ridgeline at a later date, it is easy because there is no portion to be redone by any of the construction methods of Examples 1 to 8. 9. Although we do not take any measures to fix the covering plate to the levee soil, we never fall to the paddy field side even if there is an earthquake because we use the moment of force due to the own weight of the covering plate. It's safe. 10. In the case where the covering plates are joined together, if a defect occurs at a certain place, the repair will be a great task, but in the present invention, they are not joined and are independent of each other. It is only necessary to handle the covering plate at the defective part. 11. Once constructed, it can be used semi-permanently, and considering the machinery, pesticides, and labor costs required for repairing ridges, mowing, spraying insecticides, etc., which are repeated every year, the present invention is a better measure after a certain period of time. . 12. Using the closed season when the paddy fields are not flooded, it can be easily constructed by the farmers themselves. 13. It frees the agricultural workers from the meaningless and laborious work that is repeated every year, and helps the successor to make rice farming attractive.
