Description
この発明は、道路における隙間部の修繕方法に関する。 The present invention relates to a method for repairing a gap in a road.
近年、道路維持修繕工事は、道路建設の進展および社会情勢の変化に伴って、一般道路・高速道路とも、繰り返し型の維持管理が目立つようになり、毎年膨大な予算が必要となっている。 In recent years, with the progress of road construction and changes in social conditions, road maintenance and repair work has become repetitive maintenance management on both general roads and highways, and an enormous budget is required every year.
そして、これらの維持管理作業には、多大な経費を必要とすると同時に、管理作業に道路規制による車両の渋滞を招いたり、場合によっては作業中に、作業員が走行車両によって思わぬ人身事故に発展する場合もあった。 These maintenance and management operations require a large amount of expenses, and at the same time, traffic congestion due to road regulations is incurred in the management operations. In some cases, workers can develop unexpected accidents due to traveling vehicles. There was also a case.
しかしながら、本来の技術では、以下に示すとおりの吹付ウレタンに対する有利な条件を考慮し、道路除草工、亀裂・破壊の拡大防止をする必要があり、シート貼付けでは、Ｒ部分や凹凸の激しい箇所では、施工方法に制限があった。例えば、特許文献１のように。
そこで、この発明は、道路の構造上における経年後に発生するアスファルト舗装材とコンクリート製品等との隙間に発生する雑草を長期間に渡って撲滅することを目的とし、また、構造物の宿命といわれる亀裂・破壊を保護し、かつ拡大を防止するための、簡単で、確実・迅速な施工が可能な道路における隙間部の修繕方法を開発することにある。 Therefore, the present invention aims to eradicate weeds generated in the gaps between asphalt pavement materials and concrete products, etc. that occur after a long time on the road structure, and is said to be the fate of the structure. The purpose is to develop a method for repairing gaps in roads that can be easily, reliably and quickly constructed to protect cracks and fractures and prevent expansion.
この発明による道路における隙間部の修繕方法は、道路における、例えば、コンクリートとアスファルトとの隙間部において、隙間部より繁茂する雑草を、取り除き、あるいは、伐根し、充填する土砂・塵埃等を夾雑物を除去する工程と、必要により、隙間部にモルタル充填する工程と、該隙間部を挟んで両側部に養生テープで養生する工程と、隙間部に接着剤を塗布、噴霧または吹き付けする工程と、該接着剤にウレタン樹脂を塗布、噴霧または吹き付けしてウレタン樹脂層を形成する工程と、さらに、ウレタン樹脂層に、コーティング材を塗布、噴霧または吹き付けする工程と、該コーティング材の上に必要に応じて、防滑処理を施す工程と、乾燥後、養生撤去するとを特徴とする。 The method of repairing a gap in a road according to the present invention is a method for removing dirt, dust, or the like that is removed or rooted and filled in a gap between a concrete and asphalt, for example, in a road. A step of removing an object, a step of filling mortar into the gap portion, if necessary, a step of curing with a curing tape on both sides across the gap portion, and a step of applying, spraying or spraying an adhesive to the gap portion , A step of applying a urethane resin to the adhesive, spraying or spraying it to form a urethane resin layer, a step of applying a coating material to the urethane resin layer, spraying or spraying, and a step required on the coating material According to the above, it is characterized by a step of applying a non-slip treatment and removing the curing after drying.
この発明によると、ウレタン樹脂の性質上、完全密着施工が可能であり、長期間に渡って雑草の発生を抑えることができ、毎年行う除草作業が必要でなく、道路維持面、交通安全面、景観面、及び環境面等の改善を図れる等の優れた効果を有する。 According to this invention, due to the nature of the urethane resin, it can be applied in full contact, can suppress the generation of weeds over a long period of time, does not require annual weeding work, road maintenance, traffic safety, It has excellent effects such as the improvement of landscape and environmental aspects.
又、構造物の亀裂・破壊は、構造物そのものの耐用年数にかかわる非常に重要な問題であるが、この発明の施工により、亀裂・破壊の拡大防止となり、極めて有益なる効果を奏するものである。 In addition, cracking / destruction of the structure is a very important problem related to the useful life of the structure itself. However, the construction of the present invention prevents the spread of cracking / destruction and has a very beneficial effect. .
さらに、複雑な形状の道路であっても継ぎ目なしに施工でき、しかも、超速乾性のため、施工後３０分程度で通行が可能となり、交通規制の時間が短くできる。また、強靱な仕上がりとなるため、機械的強度、耐磨耗性、耐薬品性などに優れている。しかも、広い温度範囲で弾性維持が可能のため、道路の変動にも追従できる。 Furthermore, even roads with complex shapes can be constructed without seams, and because of the ultra-fast drying, traffic can be made in about 30 minutes after construction, and traffic regulation time can be shortened. Moreover, since it has a tough finish, it has excellent mechanical strength, abrasion resistance, chemical resistance, and the like. In addition, since it can maintain elasticity over a wide temperature range, it can follow changes in the road.
さらに、着色可能のため、利用者に注意を促し、景観にもマッチするだけでなく、表面を防滑処理するため、安全性も向上する。さらに、抜群の塗膜物性を有しており、下地の挙動に対して追従性がよく、優れた耐気性もあり、舗装および構造物の亀裂・破壊部分から躯体を完全に保護し、拡大防止に効果がある。 Furthermore, because it can be colored, it not only matches the landscape with the user's attention, but also improves the safety because the surface is anti-slip. In addition, it has outstanding film properties, has good follow-up to the behavior of the base, has excellent air resistance, completely protects the frame from cracks and fractures of pavement and structures, and prevents expansion Is effective.
以下、この発明の一実施例を図面に基づいて説明すると、道路における、例えば、コンクリート縁石（イ）と歩道に敷設されたアスファルト（ロ）との隙間部（Ａ）において、隙間部より繁茂する雑草（Ｂ）を、取り除き、あるいは、伐根し、隙間部（Ａ）に詰まっている夾雑物（Ｃ）を除去する工程と、必要により、隙間部（Ａ）にモルタル等の充填物（Ｗ）を充填する工程と、該隙間部（Ａ）を挟んで両側部に養生テープ（Ｄ）で養生する工程と、養生テープ（Ｄ）（Ｄ）間であって、隙間部（Ａ）に接着剤（Ｘ）を塗布、噴霧または吹き付けして接着剤層を形成する工程と、該接着剤（Ｘ）層にウレタン樹脂（Ｙ）を塗布、噴霧または吹き付けして積層し、ウレタン樹脂（Ｙ）層を形成する工程と、さらに、ウレタン樹脂（Ｙ）層にコーティング材（Ｚ）を塗布、噴霧または吹き付けする工程と、該コーティング材（Ｚ）の上に必要に応じて、防滑処理を施す工程と、乾燥後、養生テープ（Ｄ）を撤去する工程からなることを特徴とする道路における隙間部の修繕方法から構成される。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In a road, for example, in a gap (A) between a concrete curb (I) and an asphalt (B) laid on a sidewalk, it thrives from the gap. A process of removing weeds (B) or cutting roots to remove impurities (C) clogged in the gaps (A) and, if necessary, fillings such as mortar (W) in the gaps (A) ), A step of curing with a curing tape (D) on both sides across the gap (A), and a bonding between the curing tape (D) and (D) and bonding to the gap (A) Applying, spraying or spraying the agent (X) to form an adhesive layer, and applying, spraying or spraying the urethane resin (Y) to the adhesive (X) layer and laminating the urethane resin (Y) Forming a layer and, further, a urethane resin (Y) layer It comprises a step of applying, spraying or spraying a coating material (Z), a step of applying an anti-slip treatment on the coating material (Z), if necessary, and a step of removing the curing tape (D) after drying. It is comprised from the repair method of the clearance gap in the road characterized by this.
尚、道路における隙間部（Ａ）とは、図２に全体を示すように、中央分離帯（ハ）と車道との隙間部（図３参照）、縁石と歩道との隙間部、歩・車道境界線、歩道と法面との隙間部（図４参照）、法面の隙間部（図５参照）をいうが、これらの箇所に限定されることはない。 As shown in FIG. 2, the gap (A) on the road is the gap between the median strip (C) and the roadway (see FIG. 3), the gap between the curb and the sidewalk, and the walking / roadway. The boundary line, the gap between the sidewalk and the slope (see FIG. 4), and the gap between the slope (see FIG. 5) are mentioned, but the invention is not limited to these locations.
