Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to improvements in ridge blocks.

[Prior art and problems]

Traditionally commonly used ridge blocks include:
It is as shown in Figures 5 and 6. The ridge block 1 shown in Fig. 5 not only has the required width, height, and length, but also has a relatively shallow recess 2 with a wide area, leaving peripheral edges on the left and right walls. A partition wall 3 is provided between both recesses 2, and the cross-sectional shape is I-shaped. Therefore, as shown in the figure, when this is laid in the field, it is difficult to cultivate the rice field surface that has entered the depression 2, and the cultivation becomes sloppy, and weeds tend to grow from this area. There were problems such as a lot of time and effort being required to remove it. Also, as shown in the figure,
When there is a difference in height between the paddy fields on both sides, there are problems such as an unstable state because the amount of earth and sand intervening in one of the depressions 2 facing the low paddy field is small. As a corresponding ridge block, an anchor part 4 extending horizontally on one side is formed at the lower part of the ridge block 1a, as shown in FIG. 6, so that the unstable state of the ridge block 1a can be prevented. However, the problem arises that the amount of excavated soil for installing the ridge block 1a increases, making the installation work uneconomical.

[Purpose of invention]

The present invention was developed in view of these circumstances, and it solves the problems of the conventional technology through simple and rational means. In addition, by deepening the recesses where soil enters to fill the width of the ridge blocks, we can improve the anchoring effect of the ridge blocks and improve construction efficiency. The purpose is to provide an economically advantageous ridge block at a low cost.

[Structure of the idea]

The structure of the present invention that solves the problems of the conventional technology is as follows:
A ridge block made of concrete having the required width, height, and length, with a periphery left in the upper half of one wall to form a recess that is as deep as the entire width, and a recess in the lower half of the other wall. It is characterized by forming a recess with a full width and depth, leaving a periphery in one half.

〔Example〕

The details of the embodiments will be explained with reference to the drawings.

1 is a perspective view, FIG. 2 is a perspective view of an embodiment provided with a partition wall, FIG. 3 is a perspective view of the installed state, and FIG. 4 is a side view of the same.

Reference numeral 11 denotes a concrete ridge block body 11 having the required width, height, and length. A recess 12a having a depth of the full width and a recess 12b having a depth of the full width of the ridge block main body 11 are formed in the lower half of the other wall surface, leaving a peripheral edge. As a result, the ridge block main body 11 is provided with a substantially uniform partition wall 11a having an S-shaped cross section. 1 in the diagram
Reference numeral 3 denotes connecting holes symmetrically provided in the left and right side walls of the upper recess 12a, and this connecting hole 13 matches the connecting hole 13 provided in the adjacent ridge block main body 11, as shown in FIG. As shown in the figure, they are connected using bolts and nuts 14 for connection.

Further, in the embodiment shown in FIG.
A partition wall 11b is provided integrally with the ridge block main body 11 in the vertical direction approximately in the center of a, 12b,
The purpose is to reinforce the entire ridge block 11. By making the width of the ridge block 11 of the present invention wide, it can also be used as a ridge on which bicycles, motorcycles, etc. can run.

〔effect〕

As described above, according to the configuration of the present invention, the following effects can be obtained.

(a) Not only can it be used as a permanent ridge, but (b) By using flat walls that correspond to the upper and lower recesses, it is possible to make the paddy field surface with a difference in height intersect with the flat wall surface. This eliminates the conventional uncultivated areas, rationally prevents the growth of weeds, and saves unnecessary weeding work.

(c) Since the lower recess has the same depth as the ridge block, there is a large amount of earth and sand to intervene, and there is no need to provide an anchor part as shown in Figure 6, making it easy to construct.

(d) By using only the flat wall surface corresponding to the lower depression, it is effective when used on the outer ridge of the field.
