Description

Central and side lifting device for raising concrete track and method for raising concrete track using the same

The present invention relates to a central part and lateral lifting device for raising a concrete track and a method for raising a concrete track using the same. More specifically, it includes a hydraulic jack that can raise the concrete track from the roadbed (G), but raises the central part and both sides of the concrete track at the same time so that stable and rapid repair of uneven subsidence of the roadbed is possible. It relates to an apparatus and a method for raising a concrete track using the same.

In railways, the ballast plays a role in widely distributing the load transmitted via rails and sleepers and transmitting it to the roadbed.

Furthermore, in addition to the role of transferring the load to the roadbed, the ballast prevents the movement of the sleeper that may occur due to the expansion and contraction of the rail with the ballast resistance force, absorbs the vibration of the vehicle, improves the riding comfort, and facilitates drainage. and many other roles.

These ballasts are classified into gravel ballast and concrete ballast.

The gravel ballast is relatively inexpensive to construct, maintains stability by the frictional force between the gravel, absorbs shock and noise with its own elastic force, and is relatively easy to restore when the track is twisted due to the horizontal and left and right changes of the rail. It is used a lot.

However, since gravel can be cracked, poor drainage can occur due to inflow of soil, and when hardened, it is easy to lose elasticity. Recently, concrete ballasts have been used for this purpose.

Concrete ballast has the advantages of greatly reducing maintenance work, good drainage, and less vibration and vibration of the vehicle.

However, unlike gravel ballasts, concrete ballasts require strict management measures for subsidence because, when subsidence occurs, the usability decreases and countermeasures are very limited. Suppressing the subsidence of the roadbed to an appropriate level is a very important factor in securing the driving stability of vehicles and road surfaces and reducing maintenance costs.

Figure 1a shows an exemplary view of a conventional concrete ballast repair method.

That is, in the ground repair method applied around the boundary showing the non-uniformity of the ground bearing capacity in the railway to which the concrete ballast is applied,

In order to strengthen the surrounding ground by injecting grout material when the relative settlement amount of the area where the ground bearing capacity is relatively weak to the area with the relatively strong ground bearing capacity exceeds the specified value,

A ground reinforcement method of a concrete ballast railroad is disclosed, comprising the step of burying a grout material injection pipe in advance in an area where the ground bearing capacity is relatively weak based on the boundary portion showing the non-uniformity of the ground bearing capacity.

At this time, it can be seen that the grout material injection pipe 41 is buried under the concrete ballast including the ballast stability layer 43,HSB supporting the ballast concrete layer 42,TCL, and the grout material injected It can be seen that the effect is to reinforce the reinforced subgrade (44, crushed stone layer) of the upper part of the subgrade (45).

However, in the case of post-installation on an already constructed railroad, if subsidence occurs on the concrete roadway, it is only possible to roughly predict the subsidence site through level surveying, but it is very difficult to find the exact subsidence site. ,

The grout material injected through the grout material injection pipe 41 sometimes has a much larger injection amount than expected, and even though a large amount of grout material is injected, the reinforcement effect is often not large when it is confirmed through measurement. there was.

Figure 1b shows an exemplary view of concrete ball reinforcement using a conventional injection pipe.

That is, as shown in FIG. 1b , a method of injecting the quick-setting filler 3 through the injection tube, and installing the injection tube through the TCL layer 42 and the HSB layer 43 has been introduced.

That is, as shown in Fig. 1b, an HSB layer 43 made of concrete formed on a roadbed G made of soil and sand, and a TCL layer made of concrete formed on the HSB layer 43 to support the sleepers 40 and rails ( 42) and a method for rapidly recovering the amount of settlement on a concrete ballast comprising a sleeper installed on the TCL layer (42),

After forming a through hole to pass through the TCL layer 42 and the HSB layer 43, and inserting the injection tube 1 into the through hole,

The quick-setting filler 3 is injected between the subgrade G and the HSB layer 43 through the injection pipe to raise the concrete ballast including the HSB layer 43 by a predetermined recovery amount,

The secondary filler (4) made of a fluid material is injected into the space created between the subgrade (G) and the HSB layer (43) through the injection pipe,

It is a method of filling the through-holes and, eventually, raising the concrete ballast by the amount of recovery corresponding to the amount of subsidence of the roadbed to restore the concrete ballast from the subsided state.

However, since the injection pipe formed to penetrate the TCL layer 42 and the HSB layer 43 is used, the concrete ballast can be raised by the amount of restoration corresponding to the subsidence amount of the roadbed,

Due to restrictions such as preparation work for forming a through hole and injecting the quick-setting filler (3) through the injection pipe, the construction speed is not smooth due to restrictions on environmental factors, etc., so the work extension is within about 10m,

The cause of repeated orbital misalignment is the lack of bearing capacity in many cases. However, in order to expect the concrete ballast rise by injecting the quick-setting filler (3), the repair standard for subsidence restoration is not clear and time It was necessary to develop a rapid settlement restoration method that could solve the problem by causing difficulties in operation such as excessive consumption.

Figure 1c shows an example of lifting a concrete ball using a conventional hydraulic jack.

That is, the step of drilling the pulling hole 60 to reach the reinforced roadbed 20 through the concrete ballast 30 of the railroad track;

installing a support plate 70 to the reinforcement subgrade 20 through the lifting hole 60;

Installing a support pipe (80) in the pulling hole so as to be supported on the support plate (70);

filling a fixing agent (90) between the inner surface of the lifting hole and the outer surface of the support tube (80) to fix the support tube (80) in the lifting hole (60);

A hydraulic jack 12 having a housing and a rod is installed so that it can expand and contract in the longitudinal direction of the support pipe 80 , wherein the hydraulic jack is supported on the upper surface of the spacer 11 installed on the support plate 70 with the tip of the rod installing in the support pipe 80;

coupling the reaction force lid 13 to the upper end of the support tube so that the extension force of the hydraulic jack is transmitted to the support tube by suppressing the extension of the hydraulic jack 12;

raising the support pipe 80 and the concrete ball 30 on which the support pipe is fixed by supplying a working fluid to the housing of the hydraulic jack to extend the rod;

Filling the filler 16 in the space formed between the reinforced roadbed 20 and the concrete ballast 30 by the lifting of the concrete ballast 30;

It can be seen that it includes; installing a protection cat 86 on the upper end of the exposed support pipe 80 to enable additional raising.

Accordingly, the ballast concrete layer (70, TCL) and the ballast stability layer (60, HSB) are not raised by injection of an uncertain grout material, etc., but there is an advantage in that a hydraulic jack is used, but filling between the outer surfaces of the support pipe (80) It is not easy to control the quality to sufficiently secure the fixing performance of the fixed fixing agent 90, and when lifting using only a number of hydraulic jacks, the number of installations to raise the concrete ballast 30 with an extension length of about 8-10 m is too high. There is a limit to constructability and workability due to the need for precise impression control, and although the protection cat 86 is installed on the upper end of the exposed support tube 80, the support tube 80 is Since deformation may occur accordingly, the re-raise operation cannot be guaranteed later, and there are limitations such as the need for maintenance of the protection cat 86 .

[Central part and side lifting device (100, 200) for raising concrete track of the present invention]

Figures 2a, 2b and 2c shows a configuration perspective view and an installation perspective view of the central part and side lifting devices 100 and 200 for raising the concrete track of the present invention.

First, the concrete track of the present invention has a roadbed (G) on which a reinforced roadbed (G1, crushed stone layer) is constructed, an HSB layer (320, road stability layer) is formed on the reinforced roadbed (G1), and an HSB layer ( It is constructed as a TCL layer (310, corrugated concrete layer) that is integrally constructed on the 320).

At this time, the subgrade G will be referred to as including the reinforced subgrade G1 of the upper part, and the HSB layer 320 and the TCL layer 310 are constructed integrally with concrete, so it is referred to as a concrete track 300. decide to do

When uneven settlement occurs in the roadbed G, the concrete track 300 constructed on the roadbed G also settles unevenly. In order to repair this, in the space between the roadbed G and the concrete track 300 In order to inject the grout material 170, the concrete track 300 must be raised upward from the roadbed G, and the present invention is used together with the central lifting device 100 and the side lifting device 200.

In addition, the concrete track 300 has a TCL layer 310 integrated on the HSB layer 320, and since it is constructed of concrete, a construction joint is formed, and a concrete panel structure having a constant construction or extension length and lateral width. is constructed with

Accordingly, based on the transverse width of the concrete track 300 divided in the longitudinal direction, a central lifting device 100 including a hydraulic jack is installed in the central portion to raise the central portion of the concrete track 300 using a hydraulic jack. ,

On both sides of the concrete track 300 based on the longitudinal direction, the lateral lifting device 200 including the side jigs 210 is installed to raise both sides of the concrete track 300 together with the central part.

Accordingly, in the state in which the concrete track 300 is raised by the central lifting device 100 and the side lifting device 200, the drilling hole 110 formed in the concrete track 300 while installing the central lifting device 100 is The unequal settlement of the roadbed G is repaired by injecting the grout material 170 into the impression space S between the roadbed G and the concrete track 300 using the lateral working space to be filled.

At this time, the lateral lifting device 200 is disassembled to enable reuse,

The central lifting device 100 dismantles the reaction force cap 150 , the hydraulic jack 140 , the height adjustment bolt 160 , and the fixing bracket 130 , and leaves the height adjustment jig 120 in the perforation hole 110 . to close the perforated hole 110 .

Looking at this in detail,

The lifting devices 100 and 200 of the present invention are for lifting both sides together with the central part of the concrete track 300, and it can be seen that it is configured to include the central part lifting device 100 and the side lifting device 200.

First, the concrete track 300 is composed of the TCL layer 310 installed on the HSB layer 320, as shown in FIGS. 2a, 2b and 2c, and first, the HSB layer 320 on the roadbed G. , ballast stability layer), the concrete track 300 is constructed by constructing the TCL layer (310, ballast concrete layer) on the HSB layer 320.

Therefore, in the present invention, the HSB layer 320 and the TCL layer 310 are integrated with each other in the construction process, and the central lifting device 100 and the side lifting device 200 are used to raise the concrete track 300. do.

First, the central lifting device 100 is a lifting device including a hydraulic jack to raise the central portion of the concrete track 300, as shown in FIGS. 2a, 2b and 2c.

Since the concrete track 300 has a certain extension length and a lateral width, the air and quality control of the work are determined according to the position of the impression and how to form the place of the impression, but there is no other regulation.

Accordingly, the present invention first forms a drilling hole 110 to penetrate only the concrete track 300 in order to raise the central part (the central part based on the transverse width) of the concrete track 300, and the hydraulic jack in the drilling hole 110 (140) is installed to serve to raise the central part of the concrete track (300).

The central lifting device 100 is, as shown in FIGS. 2a, 2b and 2c, a perforated hole 110, a height adjustment jig 120, a fixing bracket 130, a hydraulic jack 140, a reaction force cap 150, It includes a height adjustment bolt 160 , a grout material 170 .

First, the drilling hole 110 is formed to penetrate the TCL layer 310 or at least the HSB layer 320 constituting the concrete track 300, as shown in FIGS. 2a and 2b, and in the case of a schematic double track, the TCL layer ( 310, an island concrete layer).

Since both the TCL layer 310 and the HSB layer 320 are made of concrete, the concrete is vertically cored, but the drilling hole is not extended to the subgrade G, and the reinforced subgrade of the subgrade G G1) It can be formed up to the top surface.

These perforated holes 110 are naturally filled while injecting the grout material 170 into the impression space S of the concrete track 300 .

Next, the height adjustment jig 120 is, as shown in FIGS. 2a, 2b and 2c, a hydraulic jack 140 to be described later is installed on the upper surface to support the hydraulic jack together with the fixing bracket 130 from the bottom when the hydraulic jack 140 is operated. It plays a role and acts as a kind of lower reaction force.

Since the height adjustment jig 120 is inserted and installed in the perforation hole 110, the grout material 170 is formed so as not to interfere with the perforation hole 110 injection,

A fixing bracket 130 fixedly installed around the perforated hole 110 formed in the concrete track 300 is formed in contact with the upper surface.

Accordingly, the height adjustment jig 120 is formed to have a height corresponding to the total depth H of the perforation hole 110 to have an effective support rigidity for the pulling force.

The height adjustment jig 120 is formed to include a lower flange 121, an upper flange 122, and a vertical reinforcement 123, as shown in FIGS. 2B and 2C.

The lower flange 121 is formed as a circular steel plate in the form of a horizontal plate because the perforated hole 110 is usually constructed in a vertical cylindrical shape, as shown in FIGS. 2B and 2C , and the bottom surface is exposed by the perforated hole 110 It is set to be located on the road bed (G).

At this time, it can be seen that the bottom surface of the lower flange 121 is formed with a curved bottom surface part 125 in which the central part is curved downward, as shown in FIGS. 2b and 2c. ) is formed because the tight injection of the grout material 170 may be prevented by the lower flange 121 when it is injected.

In addition, the curved bottom portion 125 is more effective in supporting the pulling force because it acts as a wedge on the upper surface of the roadbed (G).

The upper flange 122 is formed as a circular steel plate in the form of a horizontal plate also on the upper surface of the vertical reinforcing part 122 formed on the upper surface of the lower flange 121, as shown in FIGS. 2B and 2C, and the lower flange 121 and Similarly, the central injection hole 124 is formed so that the grout material 170 can be injected from the lower flange to the upper flange. In addition, the upper surface is formed so that there is no other curved portion because the impression force must be transmitted.

The vertical reinforcing part 123 is, as shown in FIGS. 2b and 2c, if the lower flange 121 and the upper flange 122 support the pulling force by the hydraulic jack 140 in the form of a horizontal plate, the lower flange 121 and While connecting between the upper flanges 122, the load transmitted from the upper flange 122 is transferred to the lower flange 121,

The grout material 170 is formed with vertical plates radially arranged based on the central injection holes 124 so as not to interfere with the injection.

Accordingly, the vertical plate is formed between the lower surface of the upper flange and the upper surface of the lower flange as a vertical plate that does not interfere with the grout injection while effectively supporting the pulling force by the forming height and number contributing to the bending rigidity of the vertical reinforcing part 123 .

Accordingly, the lower flange 121 is the upper surface of the subgrade G exposed by the perforated hole 110 , and the upper flange 122 is inserted into the perforated hole 110 in the form of a bobbin with a size corresponding to the upper surface of the perforated hole 110 . it can be seen that

Next, the fixing bracket 130 has a bottom surface in contact with the upper surface of the upper flange 122 of the height adjustment jig 120, as shown in FIGS. 2a, 2b and 2c, but the concrete track 300 around the perforation hole 110 ) is supported on the upper surface and formed in the form of a horizontal plate fixed by a fixing bolt 131 .

For example, using a round steel plate having a certain thickness, the fixing bolt holes 132 arranged circumferentially spaced apart along the outer part are formed to pass through, and can be detached from the concrete track 300 by the fixing bolt 131 . while unifying it.

A central injection hole 134 is formed in the central part so that the grout material 170 can be injected, and this central injection hole 134 is a central injection hole 124 formed in the upper flange 122 of the height adjustment jig 120 . In order to communicate with the upper and lower parts, the injection of the grout material 170 is possible when the fixing bracket 130 is installed.

This fixing bracket 130 is integrated with the fixing bolt 131 on the upper surface of the concrete track 300, so that the lifting force by the reaction force cap 150 with the hydraulic jack 140 is built-in, as will be described later, is the fixing bracket 130 . ) to serve as an intermediate member for raising the central part of the concrete track 300 via.

In addition, in the fixing bracket 130 , the height adjustment bolt hole 133 is spaced apart from each other in a circumferential shape around the central injection hole 134 rather than the fixing bolt hole 132 so that the height adjustment bolt 160 can pass therethrough. has been

Accordingly, the height adjustment bolt 160 to be described later is inserted into the height adjustment bolt hole 133 as shown in FIG. 3c, and the lower end of the height adjustment jig 120 is set in place even when the concrete track 300 is raised. In the process of making contact with the upper surface of the upper flange 123,

It is possible to check the impression height of the concrete track 300 as long as the length inserted into the perforation hole 110, and through this, it serves to inject the grout material 170 while checking the impression height.

Furthermore, first and second connecting plates 135 and 136 are further formed on the upper surface of the fixing bracket 130 so that a reaction force cap 150 to be described later can be fixedly installed.

First, the first connection plate 135 is formed in a circular ring shape so that the hydraulic jack 140 can be located in the center, as shown in FIG. 2B , and a bolt hole corresponding to the height adjustment bolt hole 133 is formed. The height adjustment bolt 160 makes it possible to fasten through.

Next, as shown in FIG. 2b , the second connecting plate 136 has a center flange protruding upward on the inner surface of the circular ring so that the hydraulic jack 140 can also be located at the center on the upper surface of the first connecting plate 136 , as shown in FIG. 2B . As such, the reaction force cap 150 is mounted on the inner surface of the central flange, and a bolt hole corresponding to the height adjustment bolt hole 133 is also formed to enable penetration through the height adjustment bolt 160 .

The hydraulic jack 140 is vertically set to be supported on the upper surface of the fixing bracket 130 as shown in FIGS. 2B and 2C, and the cylinder is extended upward by hydraulic pressure while the cylinder is in contact with the reaction force cap 150, which will be described later. The cap 150 serves to raise the concrete track 300 together with the fixed bracket 130 .

Since this hydraulic jack 140 generates a pulling force by hydraulic pressure, it includes a hydraulic supply and adjustment device, and since at least one of the central lifting device 100 is installed along the concrete track 300, the hydraulic jack is simultaneously operated. It will also include a control unit to be operated. It is preferable that such a control unit also controls the lateral lifting device 200, which will be described later.

Accordingly, the hydraulic jack 140 may be connected to a hydraulic line for supplying and recovering hydraulic pressure, and the hydraulic line may be connected through the reaction force cap 150 .

Next, as shown in FIGS. 2a, 2b and 2c, the reaction force cap 150 is applied to the first and second connection plates 135 and 136 of the fixing bracket 130 when the pulling force by the cylinder upward extension of the hydraulic jack 140 is applied. is fixed to, so that the pulling force is transmitted to the fixing bracket 130, so that the concrete track 300 is eventually raised, and the hydraulic jack 140 is accommodated inside.

Accordingly, the reaction force cap 150 accommodates the hydraulic jack 140 while allowing the cylinder to come into contact with the upper and lower surface of the cylindrical body 151, the lower end of the second connecting plate 136 formed in the fixing bracket 130, the inner surface of the center flange to be installed on

Accordingly, the reaction force cap 150 is fixed to the fixing bracket 130 and serves as an upper support to transmit the pulling force of the hydraulic jack 140 to the concrete track 300 through the fixing bracket 130 .

Next, as shown in FIGS. 2b, 2c and 3c, the height adjustment bolt 160 is a fixing bracket ( 130) Penetrating the height adjustment bolt holes 133 and bolt holes of the first and second connecting plates 135 and 136 formed on the upper surface, the lower end is in contact with the upper surface of the upper flange 122 of the height adjustment jig 120 .

Accordingly, when the height adjustment bolt 160 is used in determining the height of the concrete track 300 by measuring or leveling, the grout material 170 can be injected in a state in which fine adjustment is possible.

Next, the grout material 170 is raised between the roadbed G and the concrete track 300 in order to maintain the raising height of the final concrete track 300 by the height adjustment bolt 160, as shown in FIGS. 2b and 3c. It is injected into the space (S) and cured.

Since the time when the grout material is injected is in the raising state of the concrete track 300, use the side form to prevent leakage to other than the impression space, and use the lateral space of the concrete track 300 to fill the impression space (S) with the grout material 170. However, if necessary, this injection is also possible with an injection hole formed separately in the concrete track 300 (not shown), and the grout material 170 through the central injection hole 134 formed in the center of the fixing bracket 130. During injection, the drilling hole 110 can also be filled with the grouty material 170 while the height adjustment jig 120 inserted into the drilling hole 110 is buried.

Next, the lateral lifting device 200 is a lifting device including a hydraulic jack to raise both sides of the concrete track 300 together with the central portion, as shown in FIG. 2A .

By raising only the central part of the concrete track 300, too many installations are required compared to the extension length and lateral width of the concrete track 300, so the present invention provides side bars 210 on both side surfaces of the concrete track 300. It is possible to raise both sides of the concrete track 300 by using the hydraulic jack 220 installed on the roadbed G with the side jigs 210 installed.

Accordingly, in the present invention, both sides of the concrete track 300 are raised, and the central part can also be raised, so it is very stable and quick to raise the concrete track 300 .

As shown in FIG. 2c , the side jig 210 may use an anchor (not shown) on the side of the TCL layer 310 of the concrete track 300 to use a horizontally protruding triangular cross-section steel frame member. It is possible to separate the anchor by removing the anchor later.

The lower end of the hydraulic jack 220 is supported by the roadbed G, and the upper end is brought into contact with the side jig 210 so that the concrete track 300 can be directly raised by the hydraulic jack operation.

In order to secure the installation space of the hydraulic jack 220 , the side jig 210 is fixedly installed on the TCL layer 310 , and the hydraulic jack uses the thickness space of the HBC layer 320 .

At this time, for the stable operation of the hydraulic jack 220, the side jig 210 is a vertical panel 211 fixed to the side of the TCL layer 310, a plurality of triangles extending apart from each other to the side of the vertical panel 211 The side panel 212 of the cross section, the vertical panel and the side panel are formed as a bottom panel 213 that integrates with each other, and a vertical bolt 214 is vertically inserted into the end of the bottom panel 213 so that the lower end is a roadbed ( G) and by setting the hydraulic jack 220 between the vertical bolts 214, a stable hydraulic jack setting and splashing phenomenon can be prevented.

[The method of raising the concrete track 300 using the central part and the side lifting devices 100 and 200 for raising the concrete track of the present invention]

3a, 3b, 3c and 3d show a flow chart of a concrete track lifting method using the central part and side lifting devices 100 and 200 for raising the concrete track of the present invention.

The method of raising the concrete track is a method of raising the concrete track 300 made of the TCL layer 310 on the HSB layer 320 on the roadbed G, in which the rail and the sleeper are integrally constructed on the upper surface, from the road bed G. , After installing the central lifting device 100 in the central part of the concrete track 300, and installing the lateral lifting device 200 on the side of the concrete track 300,

After raising the concrete track 300 by operating the central lifting device 100 and the lateral lifting device 200 at the same time, grout in the perforated hole 100 where the central lifting device 100 is installed in the lifting space (S) By injecting ashes 170, the concrete track 300 is raised and repaired.

First, looking at the process of raising the central part of the concrete track 300 using the central part lifting device 100 is as follows.

That is, as shown in FIG. 3A , the drilling hole 110 is formed in the center of the concrete track 300 and the height adjustment jig 120 is inserted into the drilling hole 110 .

The upper flange 122 of the height adjustment jig 120 is set to fit the upper surface of the perforated hole 110 of the concrete track 300 .
