Abstract
A strip of snow is applied to a support surface which is to be drained, and covered with a quick-setting concrete. When the snow melts after setting of the quick-setting concrete, the space between the support structure and the set concrete which was previously taken by the snow serves as a draining channel. The apparatus for producing the channel includes a snow-making machine, a spray nozzle for the snow, and a spray nozzle for the quick-setting concrete.
Claims14
A method of producing a draining channel at a surface, comprising the steps of applying a strip of temporarily solid flowable substance to the surface, the dimensions of the strip corresponding to the dimensions of the draining channel to be produced;
- covering the strip and the adjacent regions of the surface with a layer of quick-setting concrete;
- and allowing the solid substance to assume its flowable state and conducting the flowable substance away from between the surface and the layer so that a draining channel is formed at the surface.
