摘要:
A method of laying a section of railway track comprising a railway track as well as foundations on which the railway track is supported, comprises the following stages: the creation of the foundations - the creation of a system of a series of sleepers as well as rails by means of which the sleepers are held in parallel and at a distance from each other, - the creation of a adjusting installation, the laying of the system by way of the adjusting installation, - the supporting with regard to the foundations, by way of secondary support means, such as spindles, of the system in the position set out by the adjusting installation, - the removal of the adjusting installation, the pouring of a hardenable concrete between the series of sleepers of the system and the foundations, - the hardening of the hardenable concrete in order to create a connection between the sleepers of the system and the foundations, - implementing the pouring and hardening of the hardenable concrete while the sleepers interact with the rails and after the adjusting installation has been removed. An accurate end result can be achieved by the stages of: - removing the rails from the series of sleepers of the system after the concrete has hardened, - thereafter applying continuous rails to the series of sleepers of the system.

The invention relates to a screw device for high-adjusting and aligning rails on a track infrastructure comprising a transversal cantilever beam which clamps the rail on the underside and is fixed to a long nut (4) which is variably high guided along a high-adjusting screw (3). The inventive screw device is characterised in that the transversal cantilever beam is embodied in the form of a horizontal screw plate (7) which is pivotally arranged around a horizontal axis (20) on the long nut and on which a truck provided with a clamp fixing device (10,11) for a rail base can perpendicularly move with respect to the high-adjusting screw with the aid of a second screw device (14, 16, 17).

Disclosed is a track for magnetically levitated trains, comprising travelway plates (3) which are made of steel, are inserted in a laterally overlapping manner onto a supporting framework (1), and are provided with longitudinal support members (4) and transverse support members (5), and lateral guiding rails (7) that are connected to a covering metal sheet (5). Stator supports are fastened underneath the two outer longitudinal support members. The travelway plates rest on the supporting framework via spring bearings (10) which are connected in a fixed manner to said travelway plates and the supporting framework, and an optional fixed bearing (10).

Schwelle (2) mit Dübelstein für feste Fahrbahnen, z. B. System Getrac, bei der ein Dübelstein (5) in einer Ausnehmung (9) der, vorzugsweise als Betonschwelle ausgebildeten, Schwelle gehaltert ist, sodass er teilweise über die Sohle der Schwelle in eine nachträglich zu verfüllende Aussparung (4) der Deckschicht der festen Fahrbahn übersteht, wobei die Schwelle und der Dübelstein mit im Wesentlichen vertikalen fluchtenden Fülllöchern (13) zum Einbringen des Verfüllmaterials versehen sind.

The invention relates to a ceramic material, comprising SiO2 and Na2O and/or K2O. Said material is characterized by a porosity of over 60 % and by pores, more than 70 % of which have a pore size ranging between 0.1 and 15 νm. The ceramic material can be used as filtering material, for water storage and as adsorbent material.
