Description

FIELD OF TECHNOLOGY

The invention relates to railway (railway) transport for the manufacture and laying on a railway sheet of longitudinal blocks of reinforced concrete (reinforced concrete) sleepers connected by transverse reinforced concrete sleepers, with rails laid on the longitudinal blocks of sleepers. Joining of blocks of reinforced concrete sleepers is carried out by means of a transverse “docking” sleepers equipped with docking nodes. The technical result is the saving of consumables, reducing noise, reducing the cost of operating the railway track.

The well-known "Method of laying sleepers on the railway track", patent No. 2262565 C1 of 10.20.2005, (1), where sleepers 2.75 m long are laid with the thread of each rail with a gap of 0.5 m and are connected in the transverse direction by round wooden rods with a diameter of 30 mm.

The disadvantage is:

- longitudinal sleepers are not interconnected, which reduces the safety of the path;

- a bunch of longitudinal sleepers does not have sufficient strength.

Known reinforced concrete sleepers патент C1 of September 10, 2000 (2), which includes reinforcement, a device to increase its resistance to variable load and displacements across and along the path. The disadvantage is the low efficiency of the device to movements.

SUMMARY OF THE INVENTION

Reinforced concrete blocks of sleepers are made with the length of one rail / 25 m /, FIG. 2, or the length of one sleepers / 2.75 m /, FIG. 1, connected by reinforced concrete cross ties 2, FIG. 1, 2, spaced from each other each other at a distance of 2.8 or 4 m, depending on the complexity of the track / climb, descent, turns / or, respectively, in the middle of one sleepers / 1.35 m /, / sharp turns, arrows, etc. / and serve to increase the reliability of railway the way. The production of blocks of sleepers is carried out at a reinforced concrete plant by pouring cement of prepared reinforcement of a prestressed structure to increase the strength to variable loads (3).

For joining the blocks of reinforced concrete sleepers, a “connecting” reinforced concrete sleepers 1, FIG. 1, 2 is made, into which docking through nodes are mounted - a steel pipe (pin) 9, FIG. 1, 2, 3, with a diameter of 30 mm, thickness 3-4 mm, 40-50 cm long, included in the slot 8 of the block of reinforced concrete sleepers, FIGS. 1, 2, with a diameter of 30 + / 3-5 / mm, 3-4 mm thick, 40-50 cm long and fixed horizontal bolt 12, FIG. 1, 2 (4 pcs.) at the end of the dead joint of stacked blocks of reinforced concrete sleepers. In this case, a temperature gap and the possibility of turning the block along the axis of the railway line by an angle of 15-20 ° are provided. During the preliminary installation of the blocks of reinforced concrete sleepers, the “docking” reinforced concrete sleepers are tightly connected to the ready-made block of reinforced concrete sleepers and then joined to the subsequent block of reinforced concrete sleepers, deafly. After joining, the rails are welded or docked by means of bolts. To increase resistance to longitudinal and transverse movements under each transverse reinforced concrete sleepers, including the “docking”, are installed and fastened with a sleeper / not shown / straight or barrel-shaped cast-iron cylinders 11, FIGS. 1, 2, 3, with a diameter of up to 1 m, a height of up to 0.3 m, with a wall thickness of 3-4 mm, which are filled with ballast / gravel / and are used to level the railroad tracks, increase track reliability and reduce maintenance work.

Figure 1 shows a block of reinforced concrete sleepers with a length of one sleepers / 2.75 m /. Figure 2 shows the reinforced concrete block of sleepers in the length of one rail / 25 m /. Figure 3 shows a view A. The following notation is adopted: 1 - transverse "docking" sleepers, 2 - transverse intermediate sleepers, 3 - rail, 4 - stand under the rail, 5 - bolt, 6 - rail mount, 7 - nut, 8 - a metal socket / pipe /, 9 - a pipe / or a steel pin / with a diameter of 30 mm, in the "docking" tie, 10 - a longitudinal block of reinforced concrete sleepers, 11 - a cast-iron cylinder, 12 - a bolt connecting the pipe / pin / " docking "sleepers with a pipe in the longitudinal block of reinforced concrete sleepers.

An empirical assessment of the use of blocks of reinforced concrete sleepers gives the following technical result:

- saving of consumables from 40 to 50%;

- noise reduction of more than 30%;

- increase the speed of railway transport more than 30%;

- reduction of labor costs during the operation of the railway track up to 40%;

- reduction in the probability of derailment of wagons during a terrorist attack.

The proposed method for the manufacture and stacking of blocks in reinforced concrete sleepers is easily applicable for laying tram rails and railway rails in the subway with the addition of a third voltage removal rail (not shown), which are bolted to the “docking” and intermediate reinforced concrete sleepers.

WORK ON MANUFACTURE AND LAYING R / W TEMPLES ON THE RAILWAY

At the reinforced concrete plant, the production of reinforced concrete blocks of sleepers in the length of one sleepers and in the length of one rail is made by pouring concrete into the prestressed structure of the reinforcement of the blocks of sleepers. Separately, in the same way a “docking” railroad tie is made. A “docking” reinforced concrete railroad tie by connecting nodes simultaneously, deafly, joins with the help of horizontal bolts to one side of the reinforced concrete railroad ties block, joins two rails and stacks on the prepared railroad cloth, joins to the previously laid-out railroad rail ties block. Further, the rails are either welded or joined with bolts, observing the turns of the railway track. To lay railway tracks with sharp turns for arrows and rail joints, reinforced concrete blocks with the length of one railway sleepers are used (not shown). After laying the reinforced concrete blocks of the sleepers, the railway is filled, rammed and leveled.
