Description

本発明はスリット側溝などいわゆるU字溝の上部開口に敷設されるスリット蓋の設置高さ調整装置に関するものである。
The present invention relates to an installation height adjusting device for a slit lid laid in an upper opening of a so-called U-shaped groove such as a slit gutter.

本件出願人は、すでに既設水路へスリット蓋をモルタルで固定する工法を提案し、特許を取得して実用化している(特許第3943114号)。 The applicant has already proposed a method of fixing the slit lid to the existing waterway with mortar, and has obtained a patent and put it into practical use (Patent No. 3943114).

しかしながら実際の施工に際しては、既設水路へスリット蓋をモルタルで固定する施工につき、いくつかの課題が発生した。 However, in the actual construction, some problems have arisen in the construction of fixing the slit lid to the existing waterway with mortar.

たとえば、既設水路の「蓋かかり面」が、新設側溝の場合と同様に、平滑できれいな面であれば問題ないが、経年劣化により、多くの既設水路の蓋かかり面は荒れており、すべての蓋かかり面は一定の高さではなくなって、ある面では極端に低くなっていたり、ある面では通常の高さであったりしていた。 For example, if the "covered surface" of the existing waterway is a smooth and clean surface as in the case of the new gutter, there is no problem, but due to aging, the covered surface of many existing waterways is rough and all The covered surface was no longer at a constant height, and on one side it was extremely low, and on another side it was at normal height.

この場合の施工方法として、二つの方法が考えられる。一つ目は、一般的な調整プレート(四角い薄い鉄板)を蓋かかり面の上に設置し、スリット蓋を載せる。それでも正しい高さにならない場合は、スリット蓋を持ち上げ、追加の調整プレートを介在させ、ふたたび蓋を載せる。 Two methods can be considered as the construction method in this case. The first is to install a general adjustment plate (thin square iron plate) on the lid-covered surface and place the slit lid on it. If the height is still not correct, lift the slit lid, intervene with an additional adjustment plate, and place the lid again.

しかし、前述の様な方法であると、正しい高さとなるまで、これらを繰り返すため、手間と時間がかかってしまい、設置がスムーズに出来ない課題があった。 However, with the method as described above, since these steps are repeated until the height is correct, there is a problem that installation cannot be performed smoothly because it takes time and effort.

二つ目の方法は、低くなってしまった蓋かかり面をモルタルで補修する方法である。まず、側溝の内側に型枠を設置し、蓋かかり面にモルタルを所定の高さまで塗る。その後、モルタルが硬化した後にスリット蓋を設置する。しかしながら、この工法では型枠設置や養生に時間がかかり、スリット蓋設置工事がスムーズに出来ないとの課題がある。
The second method is to repair the lowered lidged surface with mortar. First, a mold is installed inside the gutter, and mortar is applied to the lid-covered surface to a predetermined height. Then, after the mortar has hardened, the slit lid is installed. However, this method has a problem that it takes time to install the formwork and cure, and the slit lid installation work cannot be performed smoothly.
