Description
本願発明は、寒冷地の除雪や、切削オーバーレイなどの道路舗装メンテナンスが容易で、通水性舗装にも対応できるプレキャスト横断側溝構造に関する。 The present invention relates to a precast transverse gutter structure that is easy for road pavement maintenance such as snow removal in cold regions and cutting overlay, and can also be used for water-permeable pavement.
従来、プレキャスト横断側溝にあっては、頂版にグレーチングを装着した側溝やボックスカルバートが用いられてきた。また場所打ちの側溝にあっては蓋掛り部に鋼製グレーチングを埋め込んだ構造や、或いは、特許文献１に示される側溝施工方法には、角部を頂部とした複数の等辺アングル材が並列状態で連結されて形成された側溝蓋を場所打ち側溝本体の開口部に載置し、側溝蓋の上面全面を通水性舗装と同時施工する旨がある。 Conventionally, in the precast transverse side groove, a side groove or a box culvert with a grating attached to the top plate has been used. In addition, in the case of a cast-in-place side groove, a structure in which steel grating is embedded in the lid hanging portion, or in the side groove construction method shown in Patent Document 1, a plurality of equilateral angle materials with a corner portion at the top are in a parallel state. The side groove lid formed by being connected with the above is placed on the opening portion of the cast-in-place side groove main body, and the entire upper surface of the side groove lid may be applied simultaneously with the water-based pavement.
ボックスカルバートを用いた暗渠構造では、上面に舗装を施す場合、鉄筋コンクリートの部材強度の制約から頂版の高さを薄くすることが難しかったこともあり通水断面の内高を低くし、かつ舗装の厚さを薄くして対応していた。
また、通水断面が変えられない場合は、横断部分の舗装を盛り上げるなどして対応してきた。
これにより、豪雨発生時には断面が小さくなった暗渠部で流速が低下して通水に支障が出たり、断面を同じにした場合でも舗装の盛り上がった部分の段差で通行時にはドライバーが衝撃を感じていたりしていた。
さらに舗装厚さが薄いため切削・オーバーレイなどのメンテナンス工事にも支障をきたしていた。また夏場には、舗装のズレ・剥がれを起こす要因ともなっていた。このことは特許文献１に開示される施工方法についても同様である。
In a culvert structure using box culverts, when pavement is applied to the upper surface, it is difficult to reduce the height of the top plate due to restrictions on the strength of the reinforced concrete members. The thickness of the was reduced.
If the cross section of the water flow cannot be changed, we have responded by raising the pavement of the crossing part.
As a result, when heavy rain occurs, the flow rate decreases in the underdrains where the cross section is reduced, impeding water flow, or even if the cross section is the same, the driver feels an impact when passing through the raised steps of the pavement. I was doing.
In addition, the pavement thickness is too thin, which hinders maintenance work such as cutting and overlaying. In the summer, it was also a cause of slippage and peeling of the pavement. The same applies to the construction method disclosed in Patent Document 1.
また、頂版にグレーチングを用いた側溝では、目的を取水機能に特化したため、上面に舗装が出来ず、寒冷地の除雪作業車の障害となり、鋼製グレーチングの上で車両がスリップを起こしたりするなどの課題が発生していた。
そこで、本願は、引張り強度が高く、方向性に偏りがない強度の材質と、舗装材との複合構造にすることにより、薄肉のスラブを成型し、又、側面にずれ止め体を付設して、側溝との一体化と、繰り返えされる通行車両による荷重への耐久性を図り、また、補強リブで形成される窪みに通水口を形成して排水性舗装との組み合わせにより路面の排水機能を図るプレキャスト横断側溝を提供するものである。
In addition, the gutters that use grating on the top plate specialize in the water intake function, so it is impossible to pave on the top surface, hindering snow removal work vehicles in cold regions, causing the vehicle to slip on the steel grating. There was a problem such as.
Therefore, the present application forms a thin-walled slab by using a composite structure of a material with high tensile strength and strength that has no bias in directionality, and a pavement material, and a slip stopper is provided on the side surface. Drainage function of road surface by combining with side groove and durability against load by repeated passing vehicles, and also by forming drainage opening in recess formed by reinforcing rib and drainage pavement A precast transverse groove is provided.
