Description

Structure of a gravel track for vitality using sleeper fixing and support devices and its construction method

The present invention relates to a structure of a gravel track for vitality and a construction method thereof, and more specifically, a displacement resistance force in the longitudinal and transverse axial directions to enable the construction of binder injection for vitalization of the gravel track without hindering the operation of the train. (Displacement Resistance) It relates to the structure of the gravel track and its construction method using a sleeper fixing and supporting device capable of securing (Displacement Resistance).

In general, it is widely known that a track on which a train or the like travels is provided with a roadbed on a roadbed, and sleepers and rails are disposed on the roadbed.

Here, the ballast widely distributes the train load transmitted from the rails and sleepers, transmits them to the roadbed, and fixes the sleepers in a predetermined position. As a track material, gravel (or crushed stone) or concrete is used.

In the structure of such a track, it is common to arrange sleepers on a ballast formed on a road bed, and to attach a pair of rails parallel to each other at regular intervals thereon.

Ballast, slab, etc. are included in the ballast constituting the track, and are selected in consideration of various conditions of the route. In particular, a ballast ballast track using ballast such as gravel or crushed stone is widely known.

These ballasts such as gravel and crushed stone reliably hold the sleepers, evenly distribute the load transmitted from the train through the rails and sleepers to the roadbed, give the track elasticity, and facilitate repair work such as damping. It should be there, and it has a function such as preventing the occurrence of bunting or weeds by improving the drainage of the track.

With the recent increase in the speed of trains, the track structure is gradually changing from gravel tracks to concrete tracks.

For example, in the laying of tracks such as high-speed railways, the occurrence of track errors is a big problem, and in the case of general gravel road tracks using gravel, the problem of gravel scattering during train passage is greatly emerging. Also, the use of concrete tracks is being considered.

However, in the case of such a concrete track, maintenance is difficult when the concrete track is damaged, and there are disadvantages such as a long construction period due to the curing of the concrete.

On the other hand, the supporting methods for horizontal loads used in domestic and foreign asphalt roadbeds and tracks so far are shear keys, shear protrusions, shear anchors, and non-woven fabrics.

For example, FIGS. 1A and 1B are views illustrating that a shear key is used for fixing a sleeper and a slab of a viability track according to the related art, respectively.

1A and 1B, the shear key 10 may be used for fixing the sleeper and the slab of the viability track according to the prior art.

For example, the filler is injected through the shear pocket of the concrete panel, and the horizontal load is supported through integration with the pre-installed shear key 10 .

On the other hand, as a prior art, Korean Patent Laid-Open Patent No. 10-2006-0021689 discloses an invention titled "Construction method of a pavement track for cement mortar forcibly injected for gravel track", which will be described with reference to FIG. 1C. .

Figure 1c is a perspective view showing the forced injection process of the filler material in the construction method of the cement mortar forcibly injected pavement track for the gravel ballast according to the prior art.

As shown in Figure 1c, the construction method of the cement mortar forced injection type pavement track for gravel ballast according to the prior art,

replacing the large sleeper 23 and the variable fastener while maintaining the existing islanding layer 26; coupling the track 27 to the large sleeper 23 using a variable fastener;

adjusting the position of the trajectory (27); forming an injection hole 24 for injecting the filler 25 into the large sleeper 23; and

The filler 25 is forcibly injected into the ballast layer 26 through the injection hole 24 using a forced injection device, and the injected filler 25 is uniformly distributed by pressure and vibration, and then cured to form a new ballast layer. including the steps of

According to the construction method of the cement mortar forced injection type pavement track for the gravel ballast according to the prior art, the construction materials required for the maintenance and repair of the track can be greatly reduced, so that the construction cost can be greatly reduced, and the construction time can be greatly reduced. can be shortened

However, in the case of the construction method of the cement mortar forced injection type pavement track for the gravel ballast according to the prior art,

While maintaining the existing gravel bedrock layer, replace the large sleeper and variable fasteners, connect the rail to the large sleeper using the flexible fastener, adjust the position of the rail, and inject filler through the large sleeper to create a new pavement will form a trajectory.

However, in the case of the construction method of the cement mortar forced injection type pavement track for the gravel ballast according to the prior art, there is a problem in that it is not possible to secure the displacement resistance in the longitudinal direction or the transverse direction of the sleeper on which the rail is installed.

On the other hand, the gravel ballast track is a track structure that is premised on maintenance. Maintenance is required.

In order to reduce such maintenance manpower and cost, the new railway adopts a concrete track structure, but in Korea, gravel-shaped track still occupies most of the railroad.

In Korea, the current maintenance methods for gravel ballast tracks include replacement, cleaning, or compaction by MTT (Multiple tie tamper). is becoming

In Korea, pavement track (rapid hardening track) or B2S track method have been developed as methods for improving gravel roadways, but maintenance is impossible, such as expensive construction cost, daily construction amount limit, and future linear correction, and construction joints are inevitable. The lack of it is pointed out as a disadvantage.

Meanwhile, overseas, as a method of making gravel ballast life, polyurethane, polymer aqueous solution, ultra-fine cement, emulsified asphalt, etc. are being developed on the gravel ballast. This is in progress.

Therefore, it is urgent in Korea to develop materials and construction methods that consolidate or stabilize the gravel ballast and make it viable. Materials that can be maintained after the construction of the gravel track (future maintainability), have no construction joints, are economical, and have excellent workability. and development of a construction method is required.

The maintenance or vitalization method of the gravel roadway according to the prior art is a method of washing, replacing, or compacting gravel, a method of relocating gravel on a gravel road according to the size of gravel, or a method of making a gravel track into a slab track or fixing material It consists of methods such as stabilizing by

The methods of washing, replacing or compacting the gravel ballast and the gravel ballast rearrangement method are temporary and cannot be said to be a complete revitalization method.

In addition, in the case of Korea, the method of slab-tracking the gravel ballast, which accounts for the majority of railways, has temporal, spatial and economic limitations in terms of cost, time and future maintainability, and is The method of stabilizing the gravel ball phase using the binder is a spraying method by manpower (eg, a water stopper, an injection pump, etc.), and a clear construction method has not been established yet.

On the other hand, in the method of constructing a binder or stabilizer according to the prior art, after completely removing the gravel ballast, the gravel ballast is washed or replaced to fill the injection material, or the existing gravel ballast and an admixture are mixed and kneaded and then re-constructed, or the gravel ballast subsides It is taking the method of spraying with a water stopper, etc., in places where there is frequent contamination. However, these methods have limitations in calculating the amount of construction and the scope of construction because it is difficult to secure enough rigidity to allow a train to pass within the train blocking time.

In other words, most of the prior art is based on the spraying method by manpower, and not only the railroad tracks (sleepers and rails) but also the entire gravel ballast is removed, washed and replaced with the gravel ballast, and then the gauge is installed to construct the high binder. ,

The daily construction amount is limited because the train's blocking time is not sufficient, and there are also problems such as a relatively high construction cost and the need for a construction joint when a cement-based binder is used.
