Abstract

Rapidly curing (2 hr. at -10 degrees C or 10-30 min. at higher temp.) temporary road surface or base for permanent roads is obtained by mixing with the soil an epoxy resin (pref. based on polyamines, opt. in conjunction with other resins, also curing agents, e.g. polyamines, acetic acid and fire retarding agents, e.g. MgCl2) and applying the mixture to the surface.

Description

Verfahren zum Verfestigen von weichen und/oder nassen Böden. Process for consolidating soft and / or wet soils.

Die Erfindung betrifft ein Verfahren zum Verfestigen von Morast, weichen Böden, nassen Wiesen, zerwühlten Straßen ohne festen Untergrund usw, um diese flir Schwerfahrzeuge befahrbar oder zum Landen von Flugzeugen geeignet zu machen.The invention relates to a method for consolidating morass, soft Soils, wet meadows, rumpled streets without solid ground, etc. To make heavy vehicles passable or suitable for landing aircraft.

Gegenüber der bekannten dauernden Verfestigung des Bodens, die viel Zeit erfordert, ist eine rasche Verfestigung angestrebt, um beispielsweise eine schwierige Verkehrssituation schnell zu beseitigen bzwo vorübergehend befestigte Eilfswege zu schaffen.Compared to the well-known permanent solidification of the soil, that much Requires time, a rapid solidification is sought, for example to eliminate a difficult traffic situation quickly or where it is temporarily paved To create emergency routes.

Bislang wurden zur Verfestigung von Böden als anorganische Mittel Zement, lösliche Alkalisilikates Phosphate sowie Calciumchlorid verwendet. Als organische Mittel wurden Bitumen, Polyacrylsäure und Calciumpolyacrylat, Butaienpolymere im Verein mit Ohlorschwefel und Mineralöl, sowie ein Gemisch aus öligen Homo- oder Mischpolymerisate von 1,3 Dienen, verwendet.So far have been used to consolidate soils as an inorganic means Cement, soluble alkali phosphates and calcium chloride are used. As organic Bitumen, polyacrylic acid and calcium polyacrylate, butylene polymers im Association with Ohlorschwefel and mineral oil, as well as a mixture of oily homo- or Copolymers of 1,3 dienes are used.

Nach dem zuletzt genannten Verfahren sind zur Aushärtung des behandFSLten Bodens sehr hohe Temperaturen. und zwar 13Q-150° C während 12-t5 Stunden erforderlich, was in der Praxis kaum durchzuführen isto Die Anwendung des Zements scheitert ebenso wie die anderer Anorganica daran, daß zu lange Härtungszeiten notwendig sind und nur oberflächliche Schichten auf dem Boden geschaffen werden. Im Bezug auf die vorher genannten Nachteile ist auch Bitumen schlecht für den vorgesehenen Zweck verwendbare Die weiteren organischen Massen sind wegen ihrer öligen Beschaffenheit von Nachteil, auch läßt die erzielbare Härte zu wünschen übrig.The last-mentioned procedure is used to harden the treated Very high temperatures in the soil. namely 13Q-150 ° C for 12-t5 hours required, which can hardly be done in practice o The application of the cement also fails like those of other inorganic substances, because curing times are too long and only superficial layers are created on the ground. Regarding the before mentioned disadvantages, bitumen is also poorly usable for the intended purpose The other organic masses are disadvantageous because of their oily nature, the achievable hardness also leaves something to be desired.

Demgegenüber wird bei dem erfindungsgemäßen Verfahren mit Epoxyharzen gearbeitet, was eine überraschend schnelle und hohe Festigkeit der damit behandelten Böden mit sioh bringt.In contrast, in the method according to the invention with epoxy resins worked what a surprisingly fast and high strength of the treated with it Brings floors with sioh.

Die Epoxyharze, besonders auf Polyaminbasis, können allein, oder zusammen mit anderen Harzen, wie solche auf der Batis der Polyacrylharze bzwe ungesättigter Polyes-ter oder Polyamide, als Gießharz auf den Boden, gesprüht, eingemischt odO als festes Material aufgestreut werden. Zum schnellen oder langsameren Aushärten können den Epoxyharzen Polyamine, tertiäre Amine, Essigsäure und Acetate zugegeben werden; bei den Gemischen der Epoxyharze mit ungesättigten Polymeren aind nochfür diese spezifisch wirkende Härter, wie Benzoylperoxyd beizugeben, wobei letzterem noch feuerhemmende Mittel, wie Magnesiumverbindungen und/oder Gips zugeführt wird, Weiterhin können noch Epoxyharze verwendet werden, die mit geeigneten Härtern schon vorgemischt wurden Es muß als besonders überraschen betrachtet werden, daß die Eigenschaften des Systems Epoxyharz / Härters bzwe der weiteren Komponenten durch die chemischen Einflüsse des jeweiligen Bodens (Morast, Lehm, Ton, Steine, Gras, Humus usw.) nicht verloren gehen, sondern daß mit allen Komponenten eine feste Bindung eintritt, wodurch in und auf dem Boden eine tragfähige Schicht entsteht.The epoxy resins, especially those based on polyamine, can be used alone or together with other resins, such as those on the Batis of polyacrylic resins or unsaturated ones Polyes-ter or polyamides, as casting resin on the floor, sprayed, mixed in or mixed in be sprinkled on as solid material. For faster or slower curing Polyamines, tertiary amines, acetic acid and acetates can be added to the epoxy resins will; in the case of mixtures of epoxy resins with unsaturated polymers there are still add this specific acting hardener, such as benzoyl peroxide, the latter fire retardants such as magnesium compounds and / or plaster of paris is added, It is also possible to use epoxy resins that have suitable hardeners It must be regarded as particularly surprising that the properties of the epoxy resin / hardener system or the other components through the chemical Influences of the respective soil (mud, loam, clay, stones, grass, humus etc.) do not get lost, but that a firm bond occurs with all components, whereby a stable layer is created in and on the floor.
