Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that it is impossible for a work method of constructing an induction passage, which can resist phototropism and geotropism of weeds (or guard their phototropism), to apply to block joints of existing structural borders without replacing existing border blocks and leaving them as they are installed (partial replacing of structure such as existing concrete or asphalt/buildings) in any work method to improve conventional structures such as the existing concrete or asphalt and buildings (existing pavement or existing border blocks) on the prevention of weeds from growth. <P>SOLUTION: A method for preventing weeds from growth in the structures such as existing concrete or asphalt/buildings for constructing the structures such as new concrete or existing asphalt/buildings comprises forming recesses by cutting by using a cutter for the slopes of the structures/buildings where weed prevention can be performed, and filling the recesses with a filler. Thus, weeds are prevented from growth by partly replacing the structures such as the existing concrete or asphalt/buildings. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a cutting method for achieving the herbicidal effect of a structure / structure such as existing concrete or asphalt, and a method for preventing the grass of this existing concrete or structure / structure such as asphalt.

  Conventionally, technologies and / or prior art (invention) related to grass protection means (devices) on existing paved roads, existing boundary blocks, or traveling roads (structures or structures such as existing concrete or asphalt) include roadways and sidewalks. Existing concrete block (curbstone), waterway block, gutter block, interlocking block, earth retaining block, L-shaped block, wall wall Existing boundary blocks such as are installed as a simple grass protection means. This grass protection means is formed by pouring fluid pavement materials (such as concrete) such as cast-in-place concrete or asphalt on the side (wall surface) of the existing boundary block made of cured and dried concrete, and drying and hardening it. To do. Therefore, concrete shrinks mainly due to aging (aging), and a gap (joint) in a linear direction or a gap between the structure and the structure is generated at the boundary (between) the existing boundary block wall surface and the concrete wall surface. That is an unavoidable reality.

  And this gap becomes a problem. Seeds that have entered the gap and / or invaded with the flow of rainwater and / or seeds that exist in the gap grow over time and become weeds. Explaining the mechanism, earth and sand accumulate on the roadside joints due to rainwater, etc., seeds carried by the wind and rain germinate there, absorb the rainwater and nutrients in the soil and start growing (growth). The roots of weeds sense gravity and have the property of extending downwards in search of water in the ground (grounding properties). Buds grow and propagate by receiving light from the sun and photosynthesis. Also, even if there is no sediment on the roadside, if the gap is clear, if the conditions necessary for germination of seeds that flowed in with rainwater etc. are met, germination and growth will continue in this gap, and grass will emerge when sprouting on the ground. Depending on the species, it divides and ferociously breeds. The breeding of this weed can be a problem because of accidents caused by the vehicle's detection being delayed by being blocked by weeds, accidents such as traffic problems, and accidents such as falls caused by weeds, injuries, etc. . And in reality, it ’s such a serious situation. Therefore, everyone recognizes that weed treatment is important and that weed treatment (eradication) is difficult. It is known that the buds and / or roots of plants such as weeds have a property of extending at least substantially horizontally.

  If the roots of the weeds remain in the earth and sand at the joints and the like, removal of the weeds and / or propagation can be prevented by removing the earth and sand. However, in most cases, since the roots and rhizomes have entered the joints under the soil by vigorous growth of weeds, it is possible to remove the soil on the joints. In particular, it is almost impossible to remove the stock formed in this joint. Therefore, once weeds grow, they will continue to breed every year. In addition, when there are rhizomes and roots on the road surface and / or the roadbed (hereinafter referred to as the road surface), if any joints are available on this road surface, shoots will always grow out and propagate from this point. As it continues, it is difficult to prevent the removal and / or reproduction of this joint weed.

  As this kind of weed removal method, there is a herbicide spraying as a conventional simple method. This weed removal is possible for weeds that breed on the roadside, but is only temporary and is permanent. And as long as this type of joint exists, it is impossible to stop weed removal and / or weed reproduction. In addition, heavy use of herbicides is a problem because of the increase in costs and adverse effects on the environment and human livestock. Therefore, there are problems such as costly permanent mowing every year, which is extremely uneconomical, and that it is almost impossible to reduce costs.

  In order to remove (control) this type of weed, so far, weeds are physically bonded and cut off by using steel plates, rubber plates, asphalt, etc. I've been scolding you. In this method, when the contacting part is a structure and a structure, or a structure and a road, the pavement (asphalt mixture, concrete mixture, etc.) surface and the adhesion surface of the concrete block become joints by adhesion of foreign objects, and the same concrete Even in the case of bonding between composite materials, the expansion and contraction rates differ depending on the enforcement time. That is, the physically bonded material peels off sooner or later and a gap is formed at the joint. Especially in roads, where there is a lot of vibration depending on the location and / or location, it is obvious that there are many cases where joints are naturally generated and the existing concrete, asphalt, or other structures / structures are quickly separated. In such places and the like, since there are many vehicles that travel, weed breeding may cause many problems as described above.

  In view of such a situation, the present applicant does not physically cut off the joints in the structure of the herbicidal block, but makes use of the properties in the growth of weeds (light-reflecting and refracting properties) to become joints. By adopting a structure that deforms the part and resists the growth due to the phototropism of the plant, it has been demonstrated that the natural nature of this type of weed can reliably stop the growth and increase the herbicidal effect. And file several patent applications related to this. This application is mainly proposed as an effective herbicidal measure for a new road (concrete structure). One example is listed in Japanese Patent Application Laid-Open No. 2004-169544, “Structure of structure intended for weed prevention and the like and construction method of structure and structure for preventing grass” (Reference (1)), or Japanese Patent Application No. 2004-318476. There are “forms for structures intended for weed control and the like, structures using this form, and blocks intended for weed prevention having similar effects”. In this document (1) etc., it is possible to install it at a low cost by using a weedproof form in the installation of a weedproof block or in-situ (replacement) of concrete. . However, replacing existing boundary blocks on existing roads, particularly in the construction of maintenance departments, requires lifting work and concrete placement work. The actual situation is that construction is not possible. For this reason, a primitive method and / or a manual method called manual mowing is employed.

  In view of the above, the present invention is a method for creating a guideway that can counteract the reflection and weeding of weeds at the joints of the existing boundary block while maintaining the existing boundary block without replacing it, that is, the invention We propose a cutting method for achieving the herbicidal effect of existing concrete or asphalt structures / structures, and a new construction method named the existing concrete or asphalt structures / structures. . References (2) to (4) relating to this new proposal (the present invention) are outlined below.

  Document (2) is a “road surface cutting method” disclosed in Japanese Patent Application Laid-Open No. 7-3719, which includes a shallow groove having a substantially quadrangular cross section when viewed perpendicular to an asphalt pavement, and a road surface above the bottom corner of the shallow groove. This is a method of cutting a road cutter that cuts a cutting groove that is inclined toward the surface, ensuring that the adjacent parts of old and new asphalt that are generated by road construction are firmly bonded, or that the cutting cutter is not subjected to excessive force at once. This is intended.

  Reference (3) is a “road slope cutting method using a concrete cutter” disclosed in Japanese Patent Application Laid-Open No. 2000-144628, which consists of rotating a cutter blade in which a pavement horizontal plane is inclined from a secondary reference vertical direction to both sides. When forming an inclined surface, supply a desired amount of water to the cutter blade into the cutting groove to reduce cutting resistance and discharge cutting waste, and rotate the cutter blade clockwise and counterclockwise. A method of inclining and cutting the road surface with a concrete cutter that can be rotated in any of the above, the cutting waste is easily and quickly discharged out of the horizontal surface of the pavement, the cutting resistance against the cutter blade is relatively reduced, and It intends to relatively increase the discharge amount of the cutting waste onto the pavement horizontal plane.

  Further, reference (4) is a “weedproof structure for gaps in joints” disclosed in Japanese Patent Application Laid-Open No. 11-303040. The content is the surface of the gap at the interface where the concrete block or the like and the pavement are in contact with each other. It is intended to prevent weeds that grow in the interfacial gap where the concrete block or the like and the pavement are in contact with each other.

  In addition, there has been no conventional example in which a groove is provided in a structure or structure such as asphalt using a concrete cutter, and the groove has a herbicidal effect.

  The invention of the above-mentioned document (1) is a herbicidal method using a new block, and has some differences from the purpose intended by the present invention. For example, existing concrete blocks, asphalt structures and structures, etc., which achieve a herbicidal effect through a little effort and work, that is, without replacing existing boundary blocks (including separation block, street block, etc.) Keep it installed (by replacing part of existing concrete or asphalt structures / structures including this existing boundary block), and counter the weeds' refracting and flexing properties to the joints of this existing boundary block ( In this document (1), it is considered impossible to employ a method of creating a guideway that can guard the reflection and bending properties.

  The invention of Document (2) is to provide a cutting method effective for backfilling new asphalt, or to provide a method that enables cutting with an optimum slope for this cutting method. Therefore, in order to achieve the herbicidal effect intended by the present invention, the cutting method for achieving the herbicidal effect of the existing concrete or asphalt structure / structure, and the grass prevention method of the existing concrete or asphalt structure / structure It is difficult to provide.

  Further, the present invention is a method in which a groove having a shallow rectangular vertical surface is first cut and then inclined and cut with a large-diameter cutter. When seeds enter this rectangular groove (joint), weeds The possibility of breeding is a problem. Further, the inclination angle (indicated by symbol d in FIG. 5) is defined to be about 15 ° to 25 °, and it can be pointed out that it is not possible to achieve this with this inclination angle in order to guard the light reflection of weeds.

  Next, the invention of Document (3) uses the pavement horizontal plane as the primary reference, and forms the inclined surface by rotating the cutter blade inclined from the vertical direction of the secondary reference toward both sides with respect to the primary reference pavement horizontal plane. It is the structure to do. Therefore, it is effective for discharging cutting waste, but in order to achieve the weed prevention effect intended by the present invention, the cutting method for achieving the herbicidal effect of existing concrete or asphalt structures / structures, etc. The configuration is different. And, with the inclination of 2 ° to 45 ° described in the specification [0001], there is a problem in guarding the optical reflection of weeds as in the above-mentioned document (2).

  Further, as can be understood from the content of the invention, the invention of the document (4) is a weedproof sheet, which conceals the joints of the existing concrete structure and intends to achieve the object. However, this invention is a combination of an injection seal and a weedproof sheet, and problems such as complicated structure, increased cost, and ineffectiveness for joints that occur again are pointed out. it can. And this injection seal is not sufficiently familiar with existing concrete structures (existing boundary blocks, existing pavement, etc.), the above-mentioned joint occurrence probability is strong, and it is considered that sufficient herbicidal effect can be achieved over time. Absent. In addition, this invention makes the weeding method which guards the wedling method etc. of the weed prevention method which can be completed by replacing only the inclined surface and / or the part of the existing pavement for guarding the wedling property of weeds. There is no disclosure of construction methods.

  The invention of Document (4) is a herbicidal seal for gaps in joints and the like, and concrete is dried and shrunk over time (age). Or, it is considered that it is not suitable as a herbicidal measure against the occurrence of a gap between the structure and the structure.

  The invention of claim 1 is between an existing paved road (existing pavement) and an existing boundary block, existing concrete, or an existing asphalt structure / structure (such as an existing boundary block), or an existing concrete, or an existing asphalt structure.・ As a countermeasure against grass protection between joints, between joints, etc., existing pavement and / or existing boundary block, existing concrete, or a part of existing asphalt structure / structure (for example, 10 cm to 60 cm) The present invention is mainly to provide a method that can be completed by a replacement of 35 cm to 45 cm, preferably at a very low cost.
