Device for producing concrete for the substructure from road surfaces, runways or the like

The invention relates to a device for producing concrete for the substructure of road surfaces, airstrips or the like you: ~ Mixing rock, binding agent and water by means of a Wälzmisclier «

For example, a roller mixer suitable for the production of concrete has become known through Swiss Patent No. 376 Okk , but this has the disadvantage that it can only be used to produce concrete if hard, uniform rock material is available, which is all necessary contains different aggregate classes V! However, a good gravel as G ^ is in many places of the world stone material for concrete not available or must Un ^- * he will herantranbportiert great cost and effort. In many cases, when laying out remote airstrips, nothing but inferior soil is available, so that the well-known boton-collecting method, including the aforementioned WalaniiBcher, fails in this task.

The invention is based on the object, a To improve the device for a concrete production process in such a way that it does not rely on high-quality, consistently good rock material remains limited and its scope is determined is expanded

This object is achieved according to invention ¹ by an inlet chute (2) arranged on the front side for locally-standing rock material with a high degree of flasticity or high clay, loam or silt content, by means of axially extending feed devices (5; 10; 15) extending over the entire length of the roller mixer axis. for solid additives (filler, cement, lime, etc.), binding agent and water with several outlets arranged in a distributed manner (6-9; 11-1 k ; 16-I 9) and by a rolling drum that can be steplessly tilted out of the horizontal ^ position ( 1) with such coordinated mixing rooms that free-fall mixing processes are excluded.

The device is also expediently characterized by an adjustable element in the direction of the roller mixer axis Screw conveyor for introducing the solid additives (filler, cement, KaLic, etc.).

It may be an electro-mechanical locking of the feed streams rock material, lack of rock grain classes (fillers), binders, Haftmittslzusätze and water in the manner VOIgOaEIiOiX ¹ further characterized in that on failure of a clock · Koniponentenzuf the other to be shut down.

JYeso abundance of possible variations in the mixing process is necessary because of its properties sejir different mineral substance ο inferior Soil depending on your fluidity, according to yours Klobevermügen, according to their grain composition and grain size, an individual design of the mixing elements require. Only with this high variability can the mixer produce a wide range of natural occurring soils and minerals in the state the ability to be installed as a stable substructure on roads, airstrips, etc.
