本発明はコンクリート用水路の改修工法に係り、詳しく
は農業用水路、排水路等に設置されたコンクリート用水
路の亀裂箇所を完全にシールできるコンクリート用水路
の改修工法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for repairing concrete canals, and more specifically, to a method for repairing concrete canals that can completely seal cracks in concrete canals installed in agricultural canals, drainage canals, etc. Regarding renovation methods.
（従来技術）
従来、農業用用水路、排水路にはコンクリート用水路が
一定ピッチで連続的に布設されていた。(Prior Art) Conventionally, agricultural waterways and drainage channels have been constructed with concrete waterways installed continuously at a constant pitch.
しかし、コンクリート製の水路部材は基盤の挙動、コン

部材は木材を使用したものあるいはアスファルトピッチ
を流し込んだものが多く、完全に止水処理が施工されて
いないため、この目地部より漏水していた。However, concrete waterway members tend to crack in a short period of time due to the behavior of the foundation, drying shrinkage of the concrete, or expansion and contraction of the concrete due to changes in environmental temperature. Moreover, the concrete waterway mentioned above is about IQmm ~ 2
They were connected by a 0 mm joint, but these joint members were often made of wood or filled with asphalt pitch, and as they were not completely waterproofed, water leaked from this joint. .
ところで、前記のようなコンクリート用水路の亀裂発生
箇所や目地部より一旦泪水が生じると、水路下の土砂が
侵食され、更には亀裂の成長によって漏水量が多くなり
水路及び基盤が崩壊していた。By the way, once water leaks from the cracks or joints of a concrete waterway as mentioned above, the earth and sand beneath the waterway erode, and the growth of the cracks increases the amount of water leakage, causing the waterway and foundation to collapse.
特に、水路付近に民家等が存在する場合には、非常に危

採用されていた。For this reason, today it would take a huge amount of money and time to completely renovate a building with concrete, so the cracks were filled with sealants, injection materials, mortar, etc. each time. In addition, in areas where water leakage was particularly severe, a repair method was adopted in which the existing concrete waterway was partially removed, a formwork was reassembled with wood, and then concrete was poured to create a new waterway.

いる。(Problem to be solved by the invention) However, among the conventional repair methods, where local cracks are filled with sealant, mortar, etc., cracks may occur again within one year, and Even the repair method, which involves creating a new concrete waterway, had the major problem of requiring a long construction period and being expensive. Furthermore, it is almost impossible to completely renovate concrete irrigation channels.
本発明はこのような現実的な問題に対処し、コンクリー

改修工法を提供することを目的とする。The present invention deals with such practical problems and provides a method for repairing concrete irrigation channels that can be reused and economically completed in a short construction period without removing the concrete irrigation channels. With the goal.
（問題点を解決するための手段）

コンクリート用水路の改修方法にある。(Means for Solving the Problems) That is, the present invention is characterized by using at least one rubber channel member in which a core material made of a plastically deformable metal member is embedded in rubber. The present invention provides a method for repairing a concrete canal by covering the walls of an existing concrete canal in contact with each other, sealing at least the joints or ends of the canal members, and mechanically fixing them with a tightening material.

It is possible to freely follow the shape of the wall surface and be placed in close contact with the wall surface, making construction easier.Furthermore, since the rubber water channel member fully follows the behavior of concrete, even if new cracks occur in the concrete channel. The rubber water channel member does not crack even if it occurs, so it is extremely safe and can be used for a long time.

Must be completely sealed. In addition, the treatment of the top of the concrete canal (8) is to prevent rainwater from entering the gap between the concrete canal and the waterway member, and if this occurs, the concrete canal (6) is covered with a rubber waterway member (1). However, the purpose is not fully achieved.

Alternatively, multiple canals are used to cover the walls of the waterway, and at least the joints or ends of these waterway members are sealed and mechanically fixed to the concrete waterway using a tightening material. First, remove the already installed waterway. It is possible to reuse and repair in a short period of time without having to use rubber waterway members, and because it uses rubber waterway members, it fully follows the behavior of the concrete waterway and does not cause cracks in the rubber waterway members. Since it is mechanically fixed to the concrete waterway, it is stable against the flow velocity, and even if a rock falls, it will not be damaged like concrete.
