A Method For Temporarily Closing Off A Gutter Being Covered By A Grate Of A Paved Part Of The Earth's Surface; As Well As A Closing Organ For A Gutter

摘要

Method for temporarily closing off a grate (111)-covered gutter (110) of a paved part of the earth's surface (100) by means of a closing organ (130), the gutter (110) being connected to a sewage pipe (120). Thus, the draining away of contaminating liquid can be prevented. According to the invention the gutter (110) comprises a closing organ (130) comprising a valve (131), which valve (131) is fitted rotatably in the gutter (110). The valve (131) can be in a first stable position wherein the valve (131) seals. The valve can also be in a second stable position in which the valve (131) releases the gutter (110) for the discharge of liquid (rainwater) to the sewage pipe.;The invention also relates to a closing organ (130) suitable for use with the method.

1. A method for temporarily closing off a grate covered gutter, of a paved part of the earth's surface by means of a closing organ, said gutter being connected to a sewage pipe, characterized in that the gutter comprises a closing organ comprising a valve, which valve is fitted in the gutter rotatably about an axis of rotation of a valve axle, wherein the valve can be
in a first stable position wherein the valve seals against a seat, and in a second stable position in which the valve releases the gutter for the discharge of liquid to the sewage pipe,wherein the closing organ is arranged for bringing the valve from the second stable position to the first stable position by rotating about the axis of rotation of the valve axle in order to counteract draining away of liquid from the gutter into the sewage pipe, and the valve is brought in the sealing first stable position.
