The invention relates to a telescopic surface water well with an eccentrically mounted, floating cover 16, 17. The upper end of the insert pipe 11 is arranged with a circular projecting bearing flange 14 which is eccentric in relation to the axis of the insert pipe. The well cover is mounted rotatably on this bearing flange in such a manner that, on rotation of the insert pipe, it can be adjusted in the lateral direction. Moreover, the upper end of the insert pipe can be adapted in a simple manner to variations in level of the surface of the covering which occur during road construction. <IMAGE> |
