この発明は、管の埋設工事等のために掘削した溝を、短
時間に塞いで道路に仮復旧するための、掘削工事中の道
路の仮復旧方法に関するものである。[Detailed Description of the Invention] [Technical Field of the Invention] This invention is a method for temporarily restoring a road during excavation work, by quickly closing a trench excavated for pipe burying work, etc., and temporarily restoring it to a road. This relates to recovery methods.
現在性われている、都市部における道路下への管の埋設
工事等は、交通事情等によシ夜間に施工される場合が多
い。従って、埋設工事のために掘削した溝は、昼間の交
通の支障にならないように、工事中でも埋め戻して仮復
旧しなければならない。Currently, construction works such as burying pipes under roads in urban areas are often carried out at night due to traffic conditions. Therefore, trenches excavated for burial work must be backfilled and temporarily restored even during construction so that they do not interfere with daytime traffic.
第４図〜第８図は、従来の掘削工事中の道路の仮復旧方
法の１例を示す垂直横断面図である。第４図〜第８図に
示すように、従来の仮復旧は、道路２下に掘削された溝

ファルト４の路面を形成することによシ行われている。FIGS. 4 to 8 are vertical cross-sectional views showing an example of a conventional method for temporarily restoring a road during excavation work. As shown in Figures 4 to 8, the conventional temporary restoration involves putting mountain sand 9 into the groove 3 excavated under the road 2, filling it up to the vicinity of the opening of the groove 3, and then adding mountain sand. The top surface layer of the mountain sand 9 is horizontally rolled out using a rammer 10, crushed stone 11 is thrown into the top surface layer of the rolled mountain sand 9, leveled and rolled out horizontally, and finally the paving material asphalt 4 is placed and rolled out. This is done by applying asphalt 4 and forming an asphalt 4 road surface parallel to the road 2.
８は埋設された管である。8 is a buried pipe.
しかしながら、このようにして行われる従来の仮復旧方

態が何日も続けば、累積された時間の喪失は相当なもの
となる問題がある。However, the conventional temporary restoration method performed in this way takes a considerable amount of time, so it is necessary to bury pipes, connect them, etc.
This will shorten the time required for the main construction work. On average, the time required for traditional temporary restoration is 1
It accounts for about 20% of the daily work time. If this situation continues for many days, the cumulative loss of time becomes considerable.
さらに、溝に投入される山砂等はかなシの量になり、近
年山砂等の材料の値上りとともに、工事にかかる材料の
コストが高くなる問題がある。Furthermore, the amount of mountain sand, etc. that is thrown into the ditch is small, and as the price of materials such as mountain sand has risen in recent years, there is a problem that the cost of materials required for construction increases.
従ってこの発明の目的は、管の埋設工事のために掘削し

This is done as follows. That is, after putting mountain sand 9 around the pipe 8 buried in the bottom of the groove 3 and burying the pipe 8 in the mountain sand 9, the unit body 7 prepared in advance according to the shape of the groove 3 is inserted. Bury it. Furthermore, the unit bodies 7 buried in the length direction of the groove 3 are sequentially inserted and connected with the jig 6 to close the entire groove 3, and then the square steel pipes 1.1 . . . On the upper surface of the top layer, the asphalt 4 is placed and rolled out to form a road surface that is horizontal to the ground surface of the road 2.
なお、溝３内に管８等が埋設されていないときは、ユニ
ット体７のみで、溝３の開口部付近まで溝３を塞ぐ。Note that when the pipe 8 or the like is not buried in the groove 3, the unit body 7 alone closes the groove 3 up to the vicinity of the opening of the groove 3.
ユニット体７は、上下に２層に分割して、まず下層のユ
