The modifications concern the inner section of the adjustable well and the cover which: a) is constructed every time the asphalt is changed to such height so that is aligned with the new asphalt b) the cover is incorporated from the foundry so that it becomes a uniform body so that the adjustable well consists of two sections: the outer section that is embedded in the ground, and the inner section with the incorporated cover sitting on a recess of the outer section c) the incorporated cover is installed in such manner that a recess is formed which is filled with asphalt so that a the asphalt is uniform and d) the recessed cover is separate and rests on a pedestal that is constructed on the interior wall of the inner section. e) In cases where the well is used for collection of rainwater (grid), the cover will have ridges in parallel to the water flow, f) In any case, the adjustable well comes in all geometrical shapes, types and dimensions. |
