Description
本発明は、堤防道路にガードレールを設置するための技術に関するものである。 The present invention relates to a technique for installing a guard rail on a dike road.
河川の堤防等に道路を構築した、いわゆる堤防道路が重要な交通路となりつつあるが、多くの堤防道路では河川法の規定により、ガードレールが設置されていないのが現状である。 So-called embankment roads that have built roads on river embankments and the like are becoming important traffic roads, but there are currently no guardrails installed on many embankment roads due to the regulations of the river law.
現在においては、堤防の天端の表法肩・裏法肩部分を補強し、そこにコンクリートブロックを重石とする置き並べ型のガードレールを設置する方法が実用されている。 At present, there is a practical method in which the front and back shoulders of the top of the dike are reinforced, and a side-by-side guardrail is installed with a concrete block as the weight.
またこの他の先行技術としては、特開平７−２６８８３０号公報並びに特開平９−１３２９０６号公報のように、コンクリートブロックを利用したガードレールの設置技術やガードレールの支柱の基礎を独立させる設置技術の開示がある。 As other prior arts, as disclosed in Japanese Patent Application Laid-Open No. 7-268830 and Japanese Patent Application Laid-Open No. 9-132906, disclosure of a guard rail installation technique using a concrete block and an installation technique for independent bases of guard rail columns. There is.
しかしながら、特開平７−２６８８３０号公報で開示された技術では、コンクリートブロックを安定的に路肩に固定するためには、アンカーピンを打ち込む必要がある（請求項６参照）とされており、堤防道路には応用できない。 However, in the technique disclosed in Japanese Patent Application Laid-Open No. 7-268830, in order to stably fix the concrete block to the road shoulder, it is necessary to drive an anchor pin (see claim 6). It cannot be applied to.
特開平９−１３２９０６号公報に開示された技術では、現在実用されている技術よりも構造が複雑であり、堤防道路に応用することは困難であると言わざるを得ない。 In the technique disclosed in Japanese Patent Application Laid-Open No. 9-132906, the structure is more complicated than the technique currently in practical use, and it must be said that it is difficult to apply to a dike road.
堤防道路では、河川法によりガードレールを支持する支柱を堤防に打ち込むことができないため、一般的なガードレールの施工方法が使えない。 On the embankment road, it is not possible to drive a support supporting the guardrail into the embankment by the river method, so a general guardrail construction method cannot be used.
ゆえに現在においても多くの堤防道路では、ガードレールが設置されておらず、堤防から車両が転落する事故が多発しており、死亡事故に至る事例も少なくない。 Therefore, even today, many levee roads are not equipped with guardrails, and there are many accidents in which vehicles fall from the levee, leading to fatal accidents.
これに対して、コンクリートブロックを重石とする置き並べ型のガードレールを設置する方法が実用されているが、設置するためのコストが高く高価であるために普及していない。 On the other hand, a method of installing a side-by-side type guard rail using a concrete block as a heavy stone has been put into practical use, but it is not widespread because it is expensive and expensive to install.
上記課題を解決するために、本発明のガードレール設置工法は支柱を堤防に打ち込むことなく、ガードレールの支柱を強固に支持することが可能な工法である。 In order to solve the above-mentioned problems, the guardrail installation method of the present invention is a method that can firmly support the guardrail column without driving the column into the bank.
堤防道路は堤防の天端および裏法面に構築されており、天端上に構築された堤防道路においては、通常は天端幅より道路の幅員の方が狭く、一般道路として当該道路が使用される場合、舗装されているという特徴がある。 The embankment road is constructed on the top and back slopes of the embankment, and the embankment road built on the top of the embankment is usually narrower than the top, and is used as a general road. When done, it is characterized by being paved.
本発明では、最初に路床となる堤防の天端等の上にガードレールの支柱を取付けることが可能な構造体を敷設し、この構造体と一体化するように路盤・基層・表層等からなる舗装道路を構築することにより、当該舗装材料の重量を利用して路床上に強固で安定的に定着した、ガードレールの支持構造体を造り、これにガードレールの支柱を固定してガードレールを設置する（図１参照）。 In the present invention, a structure capable of attaching a guardrail column is first laid on the top of the embankment, which becomes the roadbed, and is composed of a roadbed, a base layer, a surface layer, and the like so as to be integrated with the structure. By constructing a paved road, a guardrail support structure that is firmly and stably fixed on the road floor using the weight of the paving material is built, and the guardrail support is fixed to the guardrail and the guardrail is installed ( (See FIG. 1).
先に述べたように、堤防道路の幅員は路床となる堤防天端等の幅より狭いため、十分な道路幅が確保されていない場合も多い。このような場合、ガードレールの支柱の取付け構造部分を持つ支柱支持鋼材を、構築される堤防道路の幅員より長く突出させることにより、堤防道路の幅員を狭めることなく支柱を取付け、ガードレールを堤防道路に設置することが可能である（図１・図３参照）。 As mentioned above, since the width of the dike road is narrower than the width of the top of the dike, which is the roadbed, there are many cases where a sufficient road width is not secured. In such a case, the column support steel material with the guard rail column mounting structure is projected longer than the width of the dyke road to be constructed, so that the column is attached without reducing the width of the dyke road, and the guard rail is attached to the levee road. It can be installed (see FIGS. 1 and 3).
本発明は、堤防道路の舗装構造の重量を利用して、ガードレールの支柱を取付けるための構造体を路床上に強固で安定的に定着させるものであるので、堤防の機能を減殺することがなく、ガードレールを設置するために特別な補強工事も必要がないため安価である。 The present invention uses the weight of the pavement structure of the embankment road to firmly and stably fix the structure for attaching the guardrail struts on the road floor, so that the function of the embankment is not diminished. It is inexpensive because no special reinforcement work is required to install the guardrail.
また、施工にあたっても特別な技術開発は必要なく、既存技術で簡単に施工することが可能である。 In addition, no special technical development is required for the construction, and the construction can be easily performed with the existing technology.
堤防道路にガードレール設備が設置されることにより、堤防道路の安全性を飛躍的に向上させることができる。 By installing guardrail equipment on the embankment road, the safety of the embankment road can be dramatically improved.
具体的な施工方法のひとつとして、Ｔ型断面の鋼材を支柱支持鋼材として使用して構造体を構成した場合を以下に示す（図２参照）。 As one specific construction method, a case where a structural body is configured using a steel material having a T-shaped cross section as a support steel material is shown below (see FIG. 2).
堤防の天端に構築される堤防道路で道路幅に余裕のない場合、最初に路床となる堤防天端上にガードレールの支柱を取付けることが可能な支柱支持鋼材を、凸部が上になるようにして、ガードレールの支柱を必要とする位置に天端を横断する方向に並べる。 When the road width is not enough on the embankment road constructed at the top of the embankment, the support is made of support steel that can be installed on the top of the embankment that will be the first floor of the embankment. In this way, the guardrail support columns are arranged in a direction crossing the top end at the position where the guardrail support is required.
支柱支持鋼材は、堤防道路の幅員より長く尚且つ、ガードレールの支柱を取付けるのに必要かつ十分な長さを路面端部から突出させていることが必要である。 It is necessary that the column support steel material is longer than the width of the embankment road and protrudes from the end of the road surface as long as necessary and sufficient to attach the column of the guard rail.
天端上に並べられた支柱支持鋼材を安定させ且つ、道路の舗装重量を十分に伝達させるために、支柱支持鋼材にＴ型断面鋼材並びにＬ型断面鋼材等（連結鋼材）を支柱支持鋼材に重ね、溶接等の手段により隣り合う支柱支持鋼材に固定する。 In order to stabilize the column support steels arranged on the top and transmit the pavement weight of the road sufficiently, the column support steel materials such as T-shaped cross-section steel materials and L-shaped cross-section steel materials (connected steel materials) are used as the column support steel materials. It fixes to the adjacent support | pillar support steel material by means, such as pile and welding.
これにより、連結鋼材にかかる堤防道路の舗装重量も支柱支持鋼材に伝わり尚且つ、支柱支持鋼材の抜けやズレを防止し、強固で安定した構造体を簡単に製作することができる。 Thereby, the pavement weight of the embankment road over the connecting steel material is also transmitted to the support column steel material, and the support column steel material can be prevented from coming off and shifting, and a strong and stable structure can be easily manufactured.
当該鋼材等は、堤防道路の舗装工事に伴う重機や完成後に通行する車両の重量に耐える強度を要求されることは言うまでもない。 Needless to say, the steel material is required to have enough strength to withstand the weight of heavy machinery associated with paving work on embankment roads and vehicles that pass after completion.
構造体は、通常想定される舗装の補修工事に影響を与えない場所に構築されることが望ましい。 It is desirable that the structure be constructed in a place that does not affect the assumed pavement repair work.
堤防道路のカーブ等の形状に対しては、連結鋼材を道路の形状に適合させることにより容易に自在な対応が可能である。 It is possible to easily cope with the shape of the curve of the embankment road by adapting the connecting steel material to the shape of the road.
舗装工事後に支柱支持鋼材に支柱並びにガードレールを取付け金物・ボルト・ナット又は溶接等により固定すれば、堤防道路へのガードレールの設置工事は完了となる。 After the paving work, the work of installing the guard rail on the dike road will be completed if the support and guard rail are fixed to the support steel material by mounting hardware, bolts, nuts or welding.
堤防道路の幅員が十分に確保可能な天端等の幅がある場合には、当該構造体の全てを構築される堤防道路の舗装構造内に埋め込んで、ガードレール設備を設置することも可能である。 If there is a width at the top, etc. that can sufficiently secure the width of the embankment road, it is possible to embed the entire structure in the paved structure of the embankment road and install guardrail equipment .
さらに、ガードレールの支柱を支持するための構造を持つコンクリート板を製作し、これを構築される堤防道路の舗装の一部として使用し、ガードレールを設置することも可能である。 Furthermore, it is also possible to manufacture a concrete plate having a structure for supporting the guardrail support and use it as a part of the pavement of the embankment road to be constructed, and install the guardrail.
