SUBSTANCE: method for maintenance of railway infrastructure using a digital railway model involves monitoring and diagnosing the condition of a railway section by monitoring and measuring the position of objects of its infrastructure and their geometric dimensions at different times using means of monitoring railway, overhead system, signalling, neutralising and blocking, synchronised on the linear coordinate of the railway and the geographical coordinate. Measurement data are processed based on a spatial three-dimensional coordinate presentation of the position and geometrical parameters of objects of the infrastructure. The obtained data are compared with data of the design spatial three-dimensional coordinate presentation of the position and geometrical parameters of the same objects of infrastructure presented in the digital model of the railway. Comparison results analysed with existing tolerance values and limitations to the position of objects and their geometry and comparison results are provided in order to bring the objects of the infrastructure to a position close to the design position, through communication channels in the railway operation service.

EFFECT: high reliability of using railway infrastructure.

SUBSTANCE: method to repair or reconstruct using a digital track model, consisting in monitoring and diagnostics of actual condition of a repaired railway section by means of monitoring and measurement of position of objects in its infrastructure and their geometric dimensions done simultaneously with the help of software and hardware installed on a single mobile facility and synchronised by track coordinate and geographical coordinate. Measurement data is processed on the basis of space 3D coordinate representation of position and geometric parameters of railway section infrastructure objects. Produced data is compared with data of rated space 3D coordinate representation of position and geometric parameters of the same objects of infrastructure that are represented in the digital track model. Results of comparison with existing values of allowances and limitations to position of infrastructure objects and their geometry are analysed. Comparison results are provided to put infrastructure objects into a position close to the rated one.

SUBSTANCE: invention may be used in construction and reconstruction of railway technical systems "earth bed - permanent way" (TS), highways, basements of structures and foundations, supports of manmade structures, power transmission lines and a a contact system at clayey soils under conditions of their overwetting and heaving. The method to reinforce a railroad bed consists in treatment of railroad bed soils with a reinforcing composition of a hydraulic binder, a mineral adsorbent and water with their subsequent compaction till full covering of ballast prism soil particles with a reinforcing composition. Treatment of earth bed soils with a reinforcing composition is carried out in the upper layer of a ballast prism. The reinforcing composition is taken in the amount of 8-12% from the ballast prism volume. A hydraulic binder in the reinforcing composition is brucite lime. A mineral adsorbent is brucite chaff.

EFFECT: increased period of TS stability during the whole normative time of its interrepair life, realisation of soil reinforcement process without removal of rail and sleeper grid.

SUBSTANCE: invention refers to repair of a railway on a concrete bed in a tunnel. Method involves raising a part of the pumping railway concrete together with rails and packers using elevating device, followed by filling in a casing on longitudinal borders of a wall of a cradle with a treatment solution and bore holes of cross-section borders of lots of a repaired way, providing tight parting of lots of a repaired way. The method further involves consistent charging the treatment solution in other bore holes, and also in a hollowness of concrete of the return arch and hollowness on a contact working area between concrete of the return arch and a primary rock.

EFFECT: restoration of design position of a way with rails and packers grid grouted in concrete in a railway tunnel in conditions of soil collapsibility, fretting of concrete contact surfaces and necessity of provision of continuous train handling with fixed speeds of train movement.

SUBSTANCE: the invention refers to area of a railway transportation and is intended for the supervisory control of a rail way. The method of supervisory control of a railway position consists in installation of device on a rail rut, measurement of the passed way, excess of rails, rail gage, registration of the obtained data and addition of values with distance between measuring elements. Installation of wheel pairs on a device frame on the one hand, is performed rigidly, and on the other hand, with possibility of swinging against a cross-section axis. A gauge is measured by installation of measuring elements on lateral surfaces of rails for measurement of distance to an inside face of rails against the frame. Measuring elements are fixed in whatever position. The wheel pairs are used in a control unit of position of a railway, one of which mounted rigidly on a device frame, and the other so that to swing against the cross-section axis fixed on a device frame. The lock elements and the additional detecting device of linear movement are included into the detecting device of measurement of a gauge. Detecting devices of measurement of a gauge are located on a frame from the interior of each rail and supplied with spring-actuated measuring elements capable of being fixed with the lock elements connected with detecting devices of measurement of a gauge.

EFFECT: increase in measurement accuracy, higher operation amenity, expansion of the cart functionality.
