Abstract

The present invention relates to a bedrock structure in which a slope face of a railway track is adjusted and a construction method thereof. According to the present invention, the slope face of the bedrock is excavated and reinforced at a predetermined angle with a train in operation so that the space occupied by the slope face of the linear bedrock structure already in operation in a downtown area can be usefully recycled, and thus the stability of excavation slope face can be improved. In addition, full reinforcement is applied to a short large-diameter slope reinforcing material and an excavation surface during excavation and reinforcement, and thus disturbance such as subsidence of an existing operation line bedrock can be minimized. The head of the short slope reinforcing material can be fully reinforced by being integrated with the front wall body, and thus stability can be ensured even at a high inclination angle. In addition, the slope face angle of the bedrock is easily cut to a planned height of a gentle slope or a steep slope during operation on which an overhead load acts after the slope face is determined to the planned height in view of the use of land, bedrock stability, and the like, and thus a newly generated space can be usefully recycled.

Description

TECHNICAL FIELD [0001] The present invention relates to a railway track construction method and a construction method thereof,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a road surface structure in which a slope of a railway track is controlled, and more particularly, to a railway track railway system in which a slope of a railway trackway is controlled to effectively recycle a space occupied by a railway road surface. And a method of constructing the roadbed structure.

In Korea, more than 70% of the nation's land is composed of mountainous areas, and railroad slopes are distributed nationwide, and in the past, railway slopes made in the past are based on strength only, not taking into account the geological and geotechnical characteristics of slopes. Most of the cases are designed and constructed in such a way that standard slope is applied and remain unstable. In Korea, about two-thirds of the annual average rainfall (1000 ~ 1,283㎜) is in a vulnerable natural condition that slope collapse is prone to occur due to the climate characteristics concentrated in summer. Recently, due to global warming, The collapse of the track or its slope has been a major problem.

Unlike other means of transportation, railways are not a means of transportation that can be detoured, so urgent restoration is urgent because it will cost a lot of money before it is recovered. In addition, due to the collapse or loss of the railway due to heavy rains or the heavy rains of Guerrilla fortresses, the cost of recovering them is increasing, and the damage is also great, and the maintenance is inconvenient. In order to recover such a line, the current emergency repair method is costly, and there are many problems in terms of quality control and maintenance.

Such a railway roadbed has the function of supporting the orbit sufficiently firmly, giving proper elasticity, preventing the weakening of the upper roadbed, and dispersing and transmitting the railroad load to the roadside. Such a roadbed has a low durability and bearing capacity due to years of use, repetitive impact loads on trains, and invasion of storms. As a result, it causes a track accident due to settlement due to intrusion into bedrock of road gravel, .

Therefore, it is required to establish aggressive measures to enhance the durability and bearing capacity of railway roadbed in order to ensure safety, speedy and accurate logistics transportation and stability of railway train operation. In addition to existing line improvement, new construction and high speed railway construction, , It is required to improve the efficiency of the new railway and shipbuilding work by securing the bedrock material that can be utilized as the railway track, extending orbital maintenance cycle through the track recovery, and standardizing or optimizing the construction.

On the other hand, in the case of overseas advanced countries, various methods such as drainage method and reinforced concrete roadbed function reinforcement method have been developed and applied to improve the bearing capacity of the old roadbed. However, in Korea, This causes the problem of pouring, sinking and lowering of bearing capacity.

1 is a view showing a railway roadbed according to a conventional technique.

As shown in Fig. 1, generally, a roadbed 31 and a treadmill 32 are installed on a roadbed 10, and a train 33 is run along the rail. The roadbed 10 has an inclined surface 20 having a slope of 1.0: 1.5 to 2.0, and occupies a large area as the height H of the rail increases. That is, since the sides of the roadbed 10 on the railway and the road form a slope 20 of 1.0 to 1.5 to 2.0 in order to ensure safety, the width of the land occupied by the slope 20 is the height H). In order to secure the safety factor, the railway roadbed (10) is slope with a slope of 1.0: 1.5 ~ 2.0 and occupies a large area as the height of the embankment increases. For example, when the height H is 5 m, the roadbed 10 can be formed so as to occupy a double-width line L of 30 m or occupy a double-width line L of 53 m when the height H is 10 m . Further, when constructing a railway track, it is common to cut natural ground or make a roadbed 10 by embanking, and the slope is called a face of slope. If the angle of the inclined surface 20 is large, there is a problem that it tends to collapse due to the ratio.

On the other hand, cut slopes are mostly found in areas that construct land or roads that are flattened by rainstorming, shorebreaking, or hill cutting. Since the cutting slope is mainly formed by artificial cutting operation, when the cut slope is left as it is, there is a risk of the slope collapse due to continuous weathering such as air contact and storm penetration. In other words, when the cohesion of the slope is weak and a large amount of storm is penetrated, the slope easily breaks down and causes an accident.

In order to prevent the occurrence of such a slope slope, it is possible to prevent the slope of the slope and to prevent the slope of the slope by constructing a wall that resists to the slope surface pressure, that is, a retaining wall on the slope periphery.

As a slope reinforcement method for such cut slopes, conventionally, a field-putting concrete retaining wall construction method has been used. In such a case, excessive work work and construction cost are required to install and dismantle the form, , The concrete had to be retained until the concrete retaining wall poured into the form was completely cured and cured, thus requiring a long period of time for construction.

FIG. 2 is a view showing a state in which a surface is cut by a conventional retaining wall and a retaining wall according to the prior art.

As shown in FIG. 2, in the conventional method of cutting the slab by the retaining wall and the retaining wall, the existing slab 20 is cut and the temporary slab 40 is installed and reinforced with the stiffener 50, A retaining wall (60) is provided on the front surface.

According to the conventional method of cutting a slab by a retaining wall and a retaining wall according to the related art, when cutting the railroad slab 20, it is possible to use a stiffener 50 having a complicated construction such as installation of a temporary slab 40 Therefore, there is a possibility that settlement may occur, and corrosion may be caused by using a conductive iron reinforcement material as the reinforcing material 50. [ In addition, the permanent structure must be sufficiently spaced from the railway load due to such a restriction, and there is a problem that the space available for cutting and securing the existing surface 20 is narrow. That is, according to the conventional art, the method of cutting the slope by the retaining wall and the retaining wall can increase the excavation disturbance area due to the use of the long stiffener 50, have.

On the other hand, Japanese Patent Application Laid-Open No. 1993-9928 discloses an invention entitled " Embossing Method of Embankment Surface " as a prior art, which will be described with reference to Fig.

Fig. 3 is a view illustrating the steepening of the embankment surface of a railway according to the conventional technique.

Referring to FIG. 3, in the conventional technique, the slope of slope surface 71 is changed to a substantially vertical slope so that the slope surface 71 is vertically spaced at a predetermined interval Or the pile group 72 and the agitated mixed pile 73 in the substantially horizontal direction according to the progress of the slope excavation. Thereafter, a tensile reinforcement material 74 such as a reinforcing bar is inserted into the agitated mixed pile 73 to construct a tensile reinforcement material. By the combination of these tensile reinforcements, the deformation at the time of construction is suppressed to be small, and the stability of the embankment is secured. After completion of the construction, spray concrete 75 is sprayed onto the entire surface of the excavation surface to construct a retaining wall, thereby stabilizing the entire embankment with a short depth of reinforcement and securing the paper 78 generated by excavation. Here, reference numeral 76 denotes an integral wall surface in which concrete is laid, and reference numeral 77 denotes a wall surface fixing plate.

According to the conventional technique of striking the embankment surface, it is possible to improve the self-sufficiency of the soil by reinforcing the previously installed embankment, and then excavate the surface to steeply tilt the slope.

As another prior art, Korean Patent Laid-open Publication No. 2014-37695, which is a patent application filed by the applicant of the present invention, discloses an invention entitled " Method of cutting a slab through excavation and reinforcement of a traveling road surface agitation type & Which will be described with reference to FIG.

FIG. 4 is a view for explaining a method of cutting a slab through excavation and reinforcement of a traveling road surface agitation system according to a conventional art.

Referring to FIG. 4, a method of cutting a slab through excavation and reinforcement of a traveling road surface agitation system according to the related art is characterized in that when a train is running on a railway roadbed constructed in the past, And the train is operated at the upper part thereof.

Next, the reinforcing member 81 is inserted into the inside of the excavation end face of the road surface 85. [ Here, the reinforcing member 81 may be a vertical wall, and the vertical wall is a short, large-diameter horizontal reinforcing column that is rapidly formed so as to minimize the subsidence of the ground. For example, it may be micro-pile. Accordingly, the short large-diameter horizontal reinforcing column is rapidly formed on the roadbed excavation surface to minimize the settlement, thereby securing the lateral resistance.

Next, the horizontally reinforcing body 83 is constructed at the same time as the roadbed agitation excavation from the upper part of the excavated section. That is, the roadbed is agitated by excavation from the upper part of the excavated section of the roadbed surface (82), and the horizontal reinforcement member (83) is installed on the excavated surface. At this time, the horizontal reinforcing member 83 is constructed by stirring the injection reinforcement grout by using the tip rotating body without removing the original roadbed soil while minimizing the amount of excavation.

Next, excavation is continuously carried out to enlarge the excavation surface, and the horizontal reinforcing member 83 is applied to the enlarged excavation surface.

Next, the wall 84 is rapidly built from the excavated surface, and the road surface 82 is cut without sinking of the top surface of the road surface. That is, since the settlement of the top surface of the road surface does not occur, the road surface 82 can be cut without interruption of train operation.

Next, the above steps are repeatedly performed until the wall 84 is completed. At this time, the wall 84 can be used as a permanent roadbed structure as an integrally-drilled wall having bending stiffness. As a result, it is possible to rapidly construct the integrally-formed bending-rigid retaining wall 84 for use as a permanent roadbed structure.

The method of slitting the road surface through excavation and reinforcement of the traveling road surface agitation system according to the prior art is a method of cutting the road surface of a railway and a road without existing sinking of the road surface, It is possible to minimize the settlement due to the excavation when cutting the road surface to utilize the land occupied by the road surface and to cut the road surface to utilize the land occupied by the road surface. , So settlement due to excavation can be minimized.

However, it is difficult to arbitrarily adjust the slope of the slope in the case of the method of cutting the slab through excavation and reinforcement in the traveling road type agitation system according to the prior art. Further, when the horizontal reinforcement member 83 and the wall member 84 are weak Therefore, there is a problem that safety is deteriorated at a high inclination angle.

[A roadbed structure that adjusts the slope of a railway track line slope]

FIG.

A road surface 210 and a treadmill 220 are installed on a roadbed 110 to control the tread pattern of the railway track line according to an embodiment of the present invention, This is applicable to railway lines.

As shown in the upper part of FIG. 5, the excavation surface reinforcement 130 and the inclined stiffener 140 are installed along the slope area on the roadbed 110, so that, as shown in the lower part of FIG. 5, 110 can be cut and removed without any obstacle at an arbitrary angle, so that a newly generated paper can be formed so that the space occupied by the surface 120 can be utilized effectively.

6 and 7, a road surface structure of a railway track line according to an embodiment of the present invention includes a road surface 110, a surface 120, an excavation surface reinforcement 130, an inclined stiffener 130, 140, 140a to 140h, and a front wall 150, and also includes an internal stiffener 160 installed in the case of a steep slope.

The excavation surface reinforcement 130 is installed to reinforce the excavation surface when excavating the slope 120 of the roadbed 110.

The inclined stiffener 140 is a large diameter stiffener that is installed to penetrate the roadbed 110 and penetrate the excavation surface reinforcement 130. Specifically, the inclined stiffener 140 is an inclined stiffener whose length is shorter than that of existing stiffeners but is a large diameter. As shown in FIG. 8, the inclined stiffener 140 includes a tensile core stiffener 143, And a stirring mixture 144 of soil (gravel) and cement. That is, although the oblique stiffener 140 has a shorter length than the existing stiffener, the large-diameter and protruding surface shapes can secure the main surface friction required for the pull-out resistance.

The front wall 150 is composed of a wall cast iron rope 151, a wall horizontal reinforcing bar 152, and a cast iron rope connecting rod 153, and is installed to reinforce the excavation front. 7, the head 145 of the inclined stiffener 140 may be connected to the front wall 150 using the connecting rod 153 of the front wall 150 of the front wall 150 so as to reinforce the excavation front, So that the inclined stiffener 140 and the front wall 150 are integrated with each other. That is, after the oblique stiffener 140 is installed, the wedge-shaped head portion 145 of the oblique stiffener 140 and the front wall 150 are connected and integrated so that the front wall 150 has a stable stability Can be improved.

Meanwhile, in the case where the slope of the slope of the slope of the planned elevation is sloping, the slope stiffener 140 is installed after the excavation face stiffener 130 is installed first, Then, the inclined stiffener 140 and the front wall 150 are connected and integrated.

In addition, when the planned elevation is steep, the vertical stiffener 160 is installed first, then the excavation surface stiffener 130 is installed, and then the sloped stiffener 140 and the front wall 150 are connected .

As shown in FIGS. 6 and 7, a road surface structure of a railway track line according to an exemplary embodiment of the present invention is formed by using a slope 120 of a roadbed panel 110 of a railway roadbed structure, It is possible to create a paper sheet, and also to apply to a case where a bridge is formed into a bridge and a three-dimensional body.

The roadbed structure of the railway track line according to the embodiment of the present invention can cut and reinforce the roadbed surface so that the slope of the railway roadbed structure during operation can be adjusted at an arbitrary angle.

The road surface structure of the railway track line according to the embodiment of the present invention can be excavated and reinforced by constructing the road surface in a stepwise manner from an arbitrary slope to a maximum depth where stability can be ensured according to the ground conditions.

The inclined stiffener 140 is formed as a short, large diameter rod-like stiffener having a protruding surface with a large diameter, and the core tensile stiffener 140 143 and a stirring mixture body 144 as a peripheral grout reinforcing material, thereby securing the frictional force necessary for the pull-out resistance.

In addition, the road surface structure of the railway track line according to the embodiment of the present invention adjusts the inclination of the railway track, and the excavation surface is entirely reinforced by integrating the oblique stiffener 140 having a short diameter and the front wall 150. At this time, by connecting the wedge-shaped head 145 of the oblique stiffener 140 and the connecting rod 153 of the front wall 150, the tensile core stiffener 143 of the short-diameter large oblique stiffener 140 and the front wall 150 ).

Meanwhile, in the case of a roadbed structure in which a railroad track line according to an embodiment of the present invention is adjusted, the excavation surface reinforcement 130 is installed according to the excavation surface inclination and stability, 160 are installed.

Here, the internal stiffener 160 is installed before excavation of the roadbed 110 to prevent deformation of the roadbed 110 due to excavation. In addition, the excavation surface reinforcement 130 is preferably installed immediately after excavation of the roadbed 110 to prevent collapse of the excavation surface.

In the case of a roadbed structure in which a railroad track line according to an embodiment of the present invention is adjusted in its inclined surface, a curved excavation front is bent so that a pedestrian 110 can support a large capacity load, such as a railway, The stability of the roadbed 110 can be increased by connecting the front wall 150 having the resistance with the wedge-shaped head 145 of the inclined stiffener 140. As the front wall 150 and the oblique stiffener 140 are integrated with each other, the slip reinforcement 140 acts as a restraining force on the excavation surface, thereby restricting settlement and horizontal displacement due to large-capacity repeated loads such as a train load .

FIG. 8 is a view for explaining the concept of installation of an inclined stiffener in a roadbed structure in which a railroad track line according to an embodiment of the present invention is adjusted in terms of a surface inclination.

The protrusion 142 is formed as a protruding surface, for example, a wave form, for increasing the frictional force between the reinforcing structure and the ground.

The tensile core stiffener 143 is formed in the form of a deformed rod for increasing frictional force with the stirring mixture 144 which is an injection material.

The stirring mixture 144 is formed by injecting the soil (or gravel) and the cement as agitating grouting material to surround the tensile core reinforcement 143.

The wedge-shaped head 145 is formed to be larger than the diameter of the tensioned core stiffener 143 so as to secure a pulling resistance and is coupled with the connecting rod 153 of the front wall 150, And is integrated with the wall 150.

The wall horizontal reinforcement 152 of the front wall 150 is disposed so as to intersect with the wall vertical reinforcement 151 and the wall horizontal reinforcement 152 of the front 11, one side is connected and fixed to the wall cast iron rope 151 at predetermined intervals, and the other side is connected to the wedge-shaped head portion 145 of the sloped stiffener 140 ).

On the other hand, according to the embodiment of the present invention, the road surface structure of the railway track line can determine the front slope and the maximum excavation depth according to the ground conditions.

FIG. 12 is a view for explaining the determination of the excavation depths in the roadbed structure in which the slope of the railroad track line is adjusted according to the embodiment of the present invention.

The slope of the front surface of the railway track line according to the embodiment of the present invention can be adjusted arbitrarily according to the purpose such as the ground conditions and the slope of the slope can be arbitrarily adjusted. .

At this time, as shown in FIG. 12, the provisional excavation surface reinforcement degree determines the maximum excavation depth including the installation of the internal stiffener 160, which is a vertical stiffener, after the stability evaluation of the excavation surface. Thereafter, the construction is completed by performing a full reinforcement until the planned slope is reached.

In the case of a roadbed structure in which the slope of the railway track line according to the embodiment of the present invention is adjusted, in order to effectively recycle the space occupied by the slope of the linear roadbed structure in the urban area, The stability of the excavation surface can be improved.
