Description
Verfahren zur Herstellung gebundener poröser, flüssigkeitsdurchlässiger Deckschichten für Straßen u. dgl. Bei den bekannten Verfahren zur Herstellung von Straßenbauten aus Kalkgestein und Wasserglas erhält man bekanntlich Deckschichten, die weitgehend wasserundurchlässig sind.Process for making bonded, porous, liquid-permeable Cover layers for roads and the like. In the known processes for the production of Road constructions made of limestone and water glass are known to have top layers, which are largely impermeable to water.
Die Erfinderin hat nun gefunden, daß man aus Kalkgesteinen und Wasserglas auch poröse, flüssigkeitsdurchlässige Deckschichten herstellen kann. Man erhält diese porösen Deckschichten, wenn man gebrochenes Kalkgestein verwendet, dem man durch geeignete Behandlung das Feingut entzogen hat. Bisher hat man es immer für unumgänglich nötig gehalten, daß das verwendete Kalkgestein einen größeren Gehalt an Feingut besaß. Als besonders gut für die Zwecke des vorliegenden Verfahrens hat sich beispielsweise Kalksteinsand von einer Körnung von i bis 4. mm erwiesen, dem man durch Waschen oder auf andere geeignete Weise das pulverförmige Feingut entzogen hat.The inventor has now found that limestone and water glass can be used can also produce porous, liquid-permeable cover layers. You get these porous surface layers, if one uses broken limestone, which one has removed the fine material through appropriate treatment. So far you always have it for It was absolutely necessary that the limestone used had a higher content possessed of fine goods. Has been considered particularly good for the purposes of the present proceedings For example, limestone sand with a grain size of 1 to 4 mm turned out to be the the powdery fine material is removed by washing or in another suitable manner Has.
Die nach dem vorliegenden Verfahren hergestellten Deckschichten 'sind gebunden, porös und wasserdurchlässig; diese Eigenschaften sind für viele Zwecke erwünscht, beispielsweise dann, wenn es sich darum handelt, größere Plätze mit einer festen, griffigen, aber auch wasserdurchlässigen Decke zu versehen. Diese Deckschichten eignen sich weiterhin vorzüglich für Sport- und Tennisplätze, Parkwege und ähnliche Straßenbauten usw. Beispiel Zur Herstellung eines Tennisplatzes bringt man auf den geeignet vorbereiteten Untergrund eine Deckschicht aus gewaschenem Kalksteinsand von einer Körnung von i bis q. mm und Wasserglas. Man mischt dazu den Kalksteinsand und das Wasserglas in einem Verhältnis von 75 bis 225 kg flüssiges Wasserglas (32 bis 36° Be) auf i cbm des Kalksteinsandes, je nach der Stärke dieses Sandes, trägt diese Mischung auf und verfestigt sie durch Walzen oder Stampfen.The top layers produced by the present process are bound, porous and permeable to water; these properties are for many purposes desirable, for example, when it comes to larger spaces with a to provide a firm, non-slip, but also water-permeable blanket. These top layers are also ideal for sports and tennis courts, park paths and the like Road constructions, etc. Example To build a tennis court one brings on the a surface layer of washed limestone sand on a suitably prepared substrate from a grain size from i to q. mm and water glass. The limestone sand is mixed with it and the water glass in a ratio of 75 to 225 kg of liquid water glass (32 up to 36 ° Be) on 1 cbm of limestone sand, depending on the thickness of this sand this mixture and solidifies it by rolling or tamping.
In ähnlicher Weise wie mit Kalkgestein lassen sich solche poröse Deckschichten auch mit anderen Gesteinen, die mit Wasserglas unter Umsetzung feste Deckschichten bilden, so z. B. mit dolomitartigen Gesteinen, eisenhaltigen Gesteinen usw., herstellen.Such porous cover layers can be created in a similar way to limestone also with other rocks that are covered with water glass while implementing solid surface layers form, so z. B. with dolomite-like rocks, ferrous rocks, etc., produce.
