Description

Wynalazek niniejszy dotyczy nawierzch¬ ni boisk, zwlaszcza zas kortów tenisowych, które wytwarza sie z tlucznia ceglanego, a jeszcze lepiej dachówkowego, zmieszanego z rozdrobnionym kamieniem wapiennym.Kamien wapienny miesza sie z tluczniem wspomnianym w stosunku np. 1 : 7. Miesza¬ nine tlucznia i kamienia wapiennego w po¬ staci warstwy ugniata sie np. walcami i po¬ krywa warstwa, utworzona z mielonej ce¬ gly lub mielonej dachówki, zmieszanej z mielonym kamieniem wapiennym, którego ilosc w tym przypadku jest nieco wieksza i wynosi np. 1 czesc na 5 czesci mielonej ce¬ gly. Nawierzchnia boiska lub kortu teniso¬ wego, wykonana w ten sposób, wykazuje wszystkie zalety kortów, wytwarzanych w sposób znany: przepuszcza wode, nie jest sliska i daje sie w razie uszkodzenia wy¬ równac zapomoca walców.Nawierzchnia niniejsza w porównaniu ze znanemi wykazuje te wyzszosc, iz mate- rjaly, uzyte do budowy boisk, sa tanie i sa¬ mo wykonywanie nawierzchni jest nadzwy¬ czaj proste. PLThe present invention relates to the surface of sports fields, in particular tennis courts, which are made of brick ballast, and more preferably tile, mixed with crushed limestone. The limestone is mixed with the ballast clay mentioned in a ratio of, for example, 1: 7. and limestone in the form of a layer are kneaded, for example, with rollers and covered with a layer of ground brick or ground tile mixed with ground limestone, the amount of which in this case is slightly greater, e.g. 1 part per 5 parts of ground brick. The surface of a sports field or tennis court, made in this way, has all the advantages of courts produced in the known manner: it is water-permeable, it is not slippery and, in the event of damage, it can be compensated by the use of rollers. that the materials used in the construction of sports fields are cheap and the construction of the surface itself is extremely simple.
