Abstract

PROBLEM TO BE SOLVED: To provide a weed prevention method and a concrete product for prevention of weeds which can easily prevent weeds from growing at an edge of a sidewalk. SOLUTION: In the method for preventing weeds of a sidewalk, a projecting part 4 is provided so as to project toward the sidewalk 1 from a location slightly lower than the level 3 of the sidewalk 1, following which asphalt 5 is placed to the level 3 close to the top surface of the part 4. And in a sidewalk comprising a plurality of concrete blocks A, B which are cast at a site so as to be arranged in properly divided areas, concrete is cast so as to form a step 9 on the edges of the blocks A, B, and thereafter asphalt 6 is filled into a nearly funnel-like cavity 10 produced at the boundary between the blocks A, B.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sidewalk weeding method and a concrete product for weeding that are devised so that weeds are not generated at the edge of the sidewalk.

[0002]

2. Description of the Related Art Since a conventional sidewalk has a structure as shown in FIG. 8, seeds of weeds 13 fly on a shoulder 2 of a sidewalk 1 or a slope 7 of a cliff, and when the seeds germinate, the roots become two shoulders. There is a drawback that it reaches the soil immediately after passing along the interface of the slope 7 of the cliff, and breeds. As shown in FIG. 9, a plurality of concrete blocks (A, B, C,
In the case of the sidewalk 1 consisting of D ...), before placing the concrete, divide it into an appropriate area with a plate material, pour the concrete into the divided part, and after hardening, Since the asphalt was filled in the gaps after the board material was extracted and the board material was extracted, when the seeds of the weed 13 that flew at the interface between the asphalt and the concrete block germinated, the roots of the weeds 13 extended almost vertically, There was a drawback that they reached the soil at the shortest distance and propagated.

[0003]

SUMMARY OF THE INVENTION The present invention has been made to solve the drawbacks described in the prior art, and a method and a method for weeding a sidewalk which can easily prevent the occurrence of weeds. It is intended to provide concrete products.

[0004]

SUMMARY OF THE INVENTION A method for weeding a sidewalk according to the present invention is provided at a position slightly lower than the level of the sidewalk on the side of the sidewalk, which is made of a concrete or the like that defines the width of the sidewalk. A protruding portion protruding from the side wall to the side of the sidewalk is provided, and asphalt is cast in close contact with the upper surface of the protruding portion to the level of the sidewalk.

[0005] The second method of weeding a sidewalk of the present invention is as follows.
When the width of the sidewalk is divided by the slope such as a shoulder and a cliff, the protrusion protruding toward the sidewalk from the slope located at a point slightly lower than the level of the sidewalk, After providing a protruding portion protruding toward the sidewalk from a side wall located at a slightly lower point, the asphalt is cast in close contact with the upper surface of the protruding portion to the level of the sidewalk. It is.

The third method of weeding a sidewalk of the present invention is as follows.
In a sidewalk composed of a plurality of concrete blocks that are divided into appropriate areas and are cast at the site, concrete is cast so that a step is formed at the edge of the concrete block, and then adjacent to the concrete block. A substantially funnel-shaped void formed at the boundary of the concrete block is filled with asphalt.

[0007] The weeding concrete product of the present invention comprises:
In a concrete product having an upright wall applied for defining the width of a sidewalk, a projecting portion protruding toward a sidewalk from a side wall of the upright wall located at a point slightly lower than the level of the sidewalk is provided. It is characterized by becoming.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings showing an embodiment of the present invention, as shown in FIG.
Road shoulder 2 consisting of concrete, etc., that partitions the width of sidewalk 1
On the sidewalk 1 side of the sidewalk 4 located at a point about several cm to 5 cm lower than the level 3 of the sidewalk 1,
After the protruding portion 5 protruding toward the sidewalk 1 is provided, the asphalt 6 is cast up to the level 3 of the sidewalk 1 closely to the upper surface of the protruding portion 5. In addition, about the shape of the protrusion part 5,
It is not particularly limited, and the reach of the root of the weed 13 extending on the interface between the asphalt 6 and the protruding portion 5 to the soil can be increased by providing wavy irregularities on the surface or providing a slight inclination upward. It may be.

Further, as shown in FIG. 2, the width of the sidewalk 1 is
When the road is partitioned by the road shoulder 2 and a slope 7 such as a cliff, a projecting portion 8 projecting toward the side of the sidewalk 1 from the slope 7 located at a point lower than the level 3 of the sidewalk 1 by about several cm to 5 cm; A protruding portion 5 protruding toward the sidewalk 1 from a side wall 4 located at a point about several cm to 5 cm lower than the level 3 of the sidewalk 1, and closely contacting the upper surfaces of the protruding portions 5 and 8. The asphalt 6 is cast to the level 3 of the sidewalk 1. The slope 7 of the cliff is usually hardened by spraying concrete.

Therefore, when the seeds of the weed 13 which flew to the shoulder 2 of the sidewalk 1 or the slope 7 germinate, the roots of the seeds 5 and 8 and the asphalt 6 which is placed in close contact with the upper surface thereof are formed. If the soil does not progress, it cannot reach the soil where nutrients can be taken, so if it germinates, it will be depleted before it reaches the soil without growing. In particular, when the weather is fine, the asphalt 6 is heated by the solar heat and reaches nearly 80 ° C in summer,
Even if there is a root that has grown at the interface between the protrusions 5 and 8 and the asphalt 6, the root is in a boiled state, and after one summer, all of the root is depleted.

As shown in FIGS. 3 to 5, on a sidewalk composed of a plurality of concrete blocks A, B, C, D,... The concrete blocks A, B, C, D,.
..Concrete is laid so that a step 9 is formed at the edge of the adjacent concrete blocks A, B,.
A substantially funnel-shaped gap 10 formed at the boundary between C, D,.
Is filled with asphalt 6. In order to form the step 9 in the concrete casting at the site, for example, as shown in FIG. 6 (a), a square member 15 of an appropriate size is fixed to the top of the plate member 14 to form a predetermined section. As shown in FIG. 6 (b), the concrete is poured into the space and hardened. Then, as shown in FIG. It can be easily formed by removing the square members 15.

Therefore, asphalt 6 and concrete
When the seeds of the weed 13 that have flown to the interface of the blocks A, B, C, D, etc. germinate, the roots advance along the interface between the step 9 and the asphalt 6 that is placed closely on the upper surface. If they do not do so, they will not be able to reach the nourishable soil, so even if they germinate, they will be depleted without growing. In particular, when the weather is fine, the asphalt 6 is heated by the solar heat, and the temperature becomes close to 80 ° C. in the summer. After a summer, they all run out.

Further, as shown in FIG. 7, in a concrete product having an upright wall 11 applied to partition the width of the sidewalk 1 or the like, the number of the upright walls 11 is more than the level 3 of the sidewalk 1. By using a weeding concrete product having protrusions 5 and 8 projecting toward the sidewalk 1 from the side wall 12 located at a point lower by about 5 cm to 5 cm, weed growth at the edge of the sidewalk 1 can be prevented. Can be prevented. FIG.
7A and 7B show an example in which a protruding portion 5 is provided on the upright wall 11, and FIGS. 7C and 7D show the upright wall 11.
The example which provided the protrusion part 5 in the lower part of FIG. FIG.
(E), (f) has shown the example which provided the protrusion part 8 in the upper part of the said upright wall 11. FIG. Each of the above products is formed in advance in a specialized factory, and is applied when it is impossible to place and form concrete on site.

[0014]

Since the present invention is constructed as described above, it is possible to prevent the generation and growth of weeds at the joints of the concrete blocks constituting the edge of the sidewalk and the road surface.
