Description

Verfahren zum Befestigen von sandigem Boden. Die Erfindung betrifft ein Verfahren zum Befestigen von sandigem Boden und zum Bau von Straßen.Method of paving sandy soil. The invention relates to a method of paving sandy soil and building roads.

Das Neue besteht darin, daß der Boden mit kolloiden Dispersionen von Zement- oder Kalkhydrat oder deren Mischungen übergossen wird, ferner in Zusätzen von Pech-, Gudron-, Asphalt- oder Teerölemulsionen und schließlich in Zusätzen von geringen Mengen einer Lösung von Wasserglas, kolloider Kieselsäure oder Aluminaten.The novelty is that the soil with colloidal dispersions of Cement or lime hydrate or mixtures thereof is poured over, also in additives of pitch, gudron, asphalt or tar oil emulsions and finally in additives of small amounts of a solution of water glass, colloidal silica or aluminates.

Ein lockerer Sandweg wird zunächst in geeigneter Weise geebnet, dann wird eine koHoide Zerteilung von ioTeilen Zement in ioo bis zoo Teilen Wasser, die in Anwesenheit eines dispersionsbeschleunigenden Mittels vermittels Plausonscher Kolloidmühlen oder ,ähnlich wirkender schnellaufender Dispergiermaschinen hergestellt wurde, gleichmäßig auf den Weg verteilt.A loose sandy path is first leveled in a suitable manner, then a koHoid division of io parts of cement into ioo to zoo parts of water, the in the presence of a dispersion-accelerating agent by means of Plauson researchers Colloid mills or, similarly acting, high-speed dispersing machines are manufactured was distributed evenly along the way.

Bei sehr lockerem tiefen Sandboden kann man eine bessere Befestigung auch dadurch erzielen, daß man in gleichmäßigen Abständen tiefe Löcher in den Sand bohrt und dann erst übergießt. Ist der Boden so locker, daß das Bohren eines Loches nicht möglich ist, so kann man die Bohrung mit einem Eisenbohrer, dessen Wand mit Löchern versehen ist, vornehmen. Diese verbleiben auch nach dem Begießen mit kolloidem Zement im Boden und bilden mit dem Zement zusammen ein Eisenbetonfundament. Diese Ausführungsart eignet sich besonders für Eisenbahndämme, Uferbefestigungen und zur Befestigung von wandernden Dünen. Zur Herstellung städtischer Straßen wird ein lockerer Sandweg, wie im ersten Beispiel beschrieben, mit einer kolloiden Zerteilung von 3 Teilen Zement und 7 Teilen Kalk in 2oo Teilen Wasser, welcher dann noch i o bis 2o Teile einer kolloiden Pech-, Gudron-, Asphalt- oder Teerölemulsion zugefügt wurden, übergossen. Die Straßenfläche kann nach dem Festwerden nochmals mit koRoiden Pechemulsionen o. dgl. übergossen werden.In the case of very loose, deep sandy soil , a better fastening can also be achieved by drilling deep holes in the sand at regular intervals and only then pouring them over them. If the ground is so loose that it is not possible to drill a hole, you can drill the hole with an iron drill, the wall of which is provided with holes. These remain in the ground even after the colloidal cement has been poured and, together with the cement, form a reinforced concrete foundation. This type of construction is particularly suitable for railway embankments, bank reinforcements and for fastening migrating dunes. To build urban roads, a loose sand road, as described in the first example, with a colloidal division of 3 parts of cement and 7 parts of lime in 2oo parts of water, which is then 10 to 20 parts of a colloidal pitch, gudron, asphalt or Tar oil emulsion were added, poured over. After it has solidified, the road surface can be doused again with solid pitch emulsions or the like.

Beim Bau von Fundamenten kann ein schnelles Hartwerden dadurch erzielt werden, daß man den kolloiden Zementdispersionen kurz vor dem übergießen eine geringe Menge (o,i bis i Prozent) Wasserglas oder koRoide Kieselsäure oder Aluminat zusetzt. Man kann aber auch erst nach der Begießung mit der Zementdispersion auf die Oberfläche eine verdünnte Lösung der genannten Stoffe aufgießen.It can harden quickly when building foundations be that one of the colloidal cement dispersions shortly before pouring a low Amount (0.1 to 1 percent) of water glass or coroid silica or aluminate added. But you can only apply the cement dispersion to the surface after it has been poured pour on a dilute solution of the substances mentioned.
