Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of a cleaning device for a concrete skeleton surface when constructing a dam.

[0002]

[Prior art and its problems]

 When constructing a dam, concrete will be sequentially layered to form a dam of a specified thickness. In constructing this dam, the concrete casting section is divided into several sections, and each section is placed and cured with a concrete thickness of about 70 cm to 100 cm per day, and then concrete is sequentially layered and placed. , Curing causes impurities (slag) to emerge on the concrete surface. Therefore, it is necessary to remove these impurities in order to pour concrete. This cleaning work is called green cutting. Conventionally, this green cut was performed by a hand-pushed electric brush. Therefore, a large amount of manpower and cleaning equipment are required to perform the green cutting work with the electric brush on the upper surface of the dam embankment of a large area, and to wash within the stipulated time for the next concrete placement. There is a problem.

An object of the present invention is to provide a cleaning device capable of performing a green cut on a concrete surface with a high cleaning efficiency by utilizing a function of a shovel car and shortening a dam construction period.

[Means for Solving the Problems]

 The structure of the present invention which solves the problems of the prior art is a cleaning means A in which a plurality of rotating brushes are arranged in series at the tip of a swing arm mounted on a shovel car along the longitudinal axis of the swing arm. Detachably mounted, the cleaning means A is composed of two sets of front and rear cleaning bodies, and only the front cleaning body can be tilted upward, and the rotary brush constituting the two sets of cleaning bodies. Among them, other rotating brushes can be swiveled around adjacent rotating brushes of each set.

[0005]

[Action]

 Using the function of a shovel car, a large area can be green-cut without requiring a lot of manpower, and cleaning can be completed in a short time and the next concrete can be placed, significantly shortening the construction period. The green cut on the slope can be done efficiently, and the traveling efficiency of the trolley can be improved.
