FRAME FOR A STORM-WATER INLET OR MANHOLE

摘要

The application concerns a frame (4) for a cover (5) of a monhole or a storm-water inlet made of concrete rings (1, 2). The frame (4) exceeds the external circumference of the upper concrete ring (2) by at least 10 cm, while a through hole (6) forming a seat for the cover (5) is provided in the upper part (7) of the frame (4). The through hole has a larger dimension than the inner diameter of the concrete rings. The frame (4) is made of flexible material having a Young's modulus of at least 7,5 N/mm2. Preferably, the material is selected from rubber, plastic or composite material.
