The manhole cover E is housed in the. An inclined guide surface F that descends outward is formed on the outer peripheral portion of the manhole cover receiving frame A, and even if the road surface C is scraped by a spike tire or a chain of a snow plow (see reference numeral G), The snow removing plate H is configured to be guided to the top B without being caught in the outer peripheral portion.

るため接続部分はより激しく削り取られてしまう。However, in the structure of the manhole cover receiving frame A, the snow removing plate H jumps up when it crosses the inclined guide surface F and falls as a shock. Due to the impact of the snow removing plate H, the upper end of the inner peripheral surface of the manhole cover receiving frame A and the outer end of the manhole cover E may be deformed, and the manhole cover E may be difficult to open. Further, the snow removing plate H scrapes off the connecting portion between the inclined guide surface F and the top B, so that the appearance of the road is impaired. Particularly, when the manhole cover receiving frame A is embedded at the start position of the uphill, the snow removing plate H tries to move so as to scoop out the manhole cover receiving frame A, so that the connecting portion is sharply scraped off. Will end up.
【０００４】そこで、本発明は除雪板が飛び上がること
がなく、かつ除雪板による削り取りが生じないマンホ−
ル蓋受枠の提供を目的とする。Therefore, according to the present invention, the snow removal plate does not fly up, and the snow removal plate is not scraped off.
For the purpose of providing a lid receiving frame.

【課題を解決するための手段】この目的を達成するため
に本発明は、外周部に傾斜案内面を備えたマンホ−ル蓋
受枠において、前記傾斜案内面を上方へ湾曲する曲面と
したものである。In order to achieve this object, the present invention is a manhole cover receiving frame having an inclined guide surface on an outer peripheral portion thereof, wherein the inclined guide surface is a curved surface curved upward. is there.
【０００６】傾斜案内面の深さを５mm以上３５mm以下、
幅を２０mm以上７５mm以下とすることが好ましい。The depth of the inclined guide surface is 5 mm or more and 35 mm or less,
The width is preferably 20 mm or more and 75 mm or less.
【０００７】[0007]
【作用】傾斜案内面は上方へ湾曲する曲面に構成されて
いるので、除雪板は頂にスム−ズに案内される。The slanting guide surface is formed as a curved surface that curves upward, so that the snow removing plate is smoothly guided to the top.

しにくくなる。If the depth is less than 5 mm, the lower end of the inclined guide surface may be exposed in a short period of time, and if the depth exceeds 35 mm, the weight of the manhole cover receiving frame becomes excessive and the handling cost increases drastically. If the width is less than 20 mm, the angle of inclination is too large to secure a sufficient depth, and if it exceeds 75 mm, the weight of the manhole lid receiving frame becomes too large and the handling cost increases drastically. It will be difficult to fill the lower side with mortar.
