Description

Structure connection part capable of absorbing deformation and reducing settlement and its construction method

The present invention relates to a structure connection part capable of reducing settling by strain absorption and a construction method thereof, and more specifically, in the construction of a structure connection part in which the backfill and the buffer part are pre-constructed, and the side wall part and the upper plate of the structure are post-constructed, the backfilling and the above-mentioned It relates to a structure connection part capable of effectively absorbing deformation and reducing settlement of the buffer part by separating the buffer part from the side wall of the structure connection part while more effectively absorbing the deformation transmitted from the structure by the buffer part between the side wall part of the structure and the top plate, and a method for constructing the same.

1A is a construction diagram of a bridge connection part of a conventional bridge structure.

That is, the construction diagram shows a state in which a bridge bearing and an expansion joint device are installed in a bridge structure through which railroads pass.

At this time, the bridge bearing is installed between the girder and the bridge substructure, and the expansion joint device is separately constructed between the abutment and the end of the girder.

Accordingly, the initial construction cost and maintenance cost due to expansion joint devices and bridge bearings are inevitably excessive.

When the span length of a bridge structure such as a concrete bridge increases, the stress at the bridge connection part inevitably increases due to the increase in temperature and the longitudinal braking load of the train. It can be seen that the cost of foundation construction is inevitably increased due to excessive load transfer.

1b is a construction diagram of a bridge connection part in a conventional Ramen structure.

In this way, in the ramen structure 50 in which the upper plate and the side wall part are integrated with each other, the horizontal force applied from the bridge connection part 20 and the earthwork part 10 to the side wall part 41 has the side wall part and the upper plate integrated with each other, so that the horizontal displacement It can be effectively resisted, but various deformation modes are experienced during use due to the temperature and traffic load from the upper plate, so that the side wall portion 51 of the ramen structure 50 is also designed to be enlarged. can

In addition, in the order of construction of the bridge connection part in which the conventional side wall part 41 is pre-constructed and the backfill 10 is post-constructed, the side wall part 41 is rigid reinforced concrete, and the backfill 10 is cement-treated gravel. Therefore, there is a limit to fundamentally solving the settlement problem due to the large difference in compressibility of the materials used.

1c and 1d illustrate a reinforcement construction diagram for preventing subsidence of the bridge connection part between the earthwork part and the side wall part of a bridge structure, which is a conventional rigid structure.

That is, the earthwork portion 10 is first formed in order to induce pre-settlement of the earthwork portion 10 at the rear of the position where the sidewall portion 30 of the bridge, which is a rigid structure, will be constructed;

On the inclined surface (left side) of the earthwork 10, a reinforcing material 22 composed of a vertical part to be in contact with the rear surface of the side wall part 21 of the bridge and a horizontal part parallel to the ground is installed,

a geotextile 23 is laid on the upper surface of the horizontal part of the reinforcing material 22, and the upper surface of the geotextile 23 is filled with a filler 24 to form a connection layer 21;

The connection layer 21 is laminated to the height of the side wall 30 by repeating the installation of the reinforcement 22, the installation of the geotextile 23, and the filling of the filler 24 to form the bridge connection 20, and It can be seen that there is

At this time, as shown in Fig. 1d, the exposed reinforcing bar 25 is connected to the reinforcing material 22 and installed so as to protrude toward the front of the vertical part of the reinforcing material 22,

By installing a formwork (not shown) for the formation of the side wall part 30 so that the exposed reinforcing bar 25 is embedded in the side wall part 30 and pouring concrete, the side wall part 30 is connected to the bridge connection part 20 ) to become one with

Therefore, the bridge connection part 20 and the earthwork part 10 are first constructed to converge the residual settlement, and then the side wall part 30 is connected and constructed to minimize the differential settlement, thereby improving the stability of the rigid structure connection part against moving loads or other applied loads. It can be seen that they are trying to secure as much as possible.

Accordingly, although the bridge connection part 20 and the earthwork part 10 are first constructed, the settlement of the bridge connection part can be prevented, but horizontal earth pressure applied from the bridge connection part 20 to the side wall part 30, the earthquake load, etc. Since expansion and contraction (horizontal deformation, displacement) is not taken into account, the cross-section of the actual side wall portion 30 has no choice but to increase, and thus there is a limit in that efficiency and economic efficiency are inevitably reduced.

Accordingly, the present invention allows the buffer part to more effectively absorb the deformation transmitted from the upper plate, the girder, and the abutment of the bridge structure, thereby eliminating the need to install an expansion joint installed on the bridge structure, thereby constructing a faster and more economical bridge structure. It is a technical task to solve the structural connection part and its construction method that can absorb deformation and reduce settlement.

In addition, the present invention can increase the efficiency of the buffer part by separating (non-integrating) the sidewall of the buffer part from the side wall of the structure connection part to make the deformation of the buffer part smoother, and the structure connection part that can effectively absorb deformation and reduce settlement and its construction Provide a method as a technical problem to be solved.

In addition, the buffer part is connected to the side wall part of the bridge structure by using the side wall of the structure connection part, so that the bridge structure can respond more efficiently to deformation, thereby increasing the efficiency of the buffer part construction. It is a technical task to solve the provision of the connection part and its construction method.

In addition, by constructing the buffer part and the backfilling of the buffer part with different material configurations, it is a technical solution to provide a structural connection part capable of absorbing deformation and reducing settlement that can effectively respond to lateral deformation of the bridge structure and its construction method make it a task

According to the structure connection part and its construction method capable of absorbing deformation and reducing settlement of the present invention, the bridge structure and the structure connection part settlement reduction and structural stability are improved by integrating the upper plate, abutment part, and girders of the bridge structure.

[Structure connection part 100 capable of absorbing deformation and reducing settlement of the present invention]

2a and 2b show a construction conceptual diagram and a configuration diagram of the structure connection part 100 capable of absorbing deformation and reducing settlement of the present invention.

First, the structure connection part 100 is, for example, in the process of constructing a bridge structure 200 that crosses a road and a railroad, the boundary section between the earthworks including the backfill 110 connected to the bridge structure 200 it means.

In addition, as shown in FIG. 2a in the structure connection part 100, the buffer part 120 is constructed between the bridge structure 200 and the backfill 110, and the buffer part 120 and the backfill 110 are longitudinal to each other. The side walls 140 are constructed in both sides (transverse direction) so as to be integrally constructed in the direction.

In addition, the buffer part 120 uses the one in which the side wall part 210 and the upper plate 220 of the bridge structure 200 are integrally constructed, as shown in FIG. 2B , and is connected to each other using the connecting material 240 The buffer unit 110 serves to absorb longitudinal and lateral deformation caused by temperature load, train load, etc. of the bridge structure 200 .

In addition, as shown in FIG. 2b , the side wall 140 is positioned on both sides of the buffer unit 120 and the backfill 110 to accommodate it, and the side wall unit 210 of the bridge structure and the side connecting material 141 are connected to each other. are used to connect them to each other.

Accordingly, the bridge structure 200 is configured to include both side wall parts 210 and a top plate 220, as shown in FIGS. 2A and 2B, and the top plate 220 is integrated between the upper inner sides of both side wall parts 210. And the top plate 220 is a slab, and a pavement layer may be installed on the top surface.

As shown in FIGS. 2A and 2B, since the bridge structure 200 is constructed of concrete, deformation occurs in the longitudinal and lateral “W” directions depending on the temperature. It is offset by bridge bearings.

However, since the expansion joint device and the bridge bearing require a lot of maintenance cost, the present invention does not install the expansion joint device and the bridge support, and the longitudinal and lateral directions due to the temperature of both side wall parts 210 and the upper plate 220 . It is made to be able to absorb the directional deformation by the buffer part 120 to be described later.

As a result, the present invention can reduce the maintenance cost of the bridge structure 200, and since the expansion joint device and the bridge support are not installed, the cross section of the bridge structure can be slimmed down, so that the bridge structure 200 construction is efficient and economical. This becomes possible.

Specifically, first, the side wall part 210 is a kind of vertical plate structure as shown in FIGS. 2A and 2B, and may be constructed by cast-in-place concrete, etc. can

Next, the top plate 220 is formed such that a pavement layer is formed on the top surface, and is integrally constructed between the upper inner side of the side wall parts 210 .

Accordingly, the bridge structure 200 is deformed in the longitudinal and lateral directions when a temperature load and a traffic load are applied. It is absorbed using the buffer part 120 of (100).

At this time, the structure connection part 100 includes a backfill 110 , a buffer part 120 , a frame of reference 130 , and a side wall 140 , as shown in FIGS. 2A and 2B .

First, the backfill 110 is constructed so as to be self-reliant in the vertical direction toward the rear surface A of both side wall parts 210 of the bridge structure 200, as shown in FIGS. 2A and 2B, both side wall parts 210 It is an earthwork body that is spaced apart from the rear surface (A) so that the buffer part 120 can be formed between the side wall parts 210, the back surface (A) and the backfill (110).

Since this backfill 110 is an earthwork body having a certain height, it is constructed so that it is spaced apart from the rear surface (A) of the side wall part 210 and vertically independent by using the reinforcement material 111 for vertical independence while resisting the earth pressure that increases downward. will do

At this time, the reason for constructing the backfill 110 so that the backfill 110 is vertically self-reliant on the rear surface A of both side wall parts 210 is that the backfill 110 is constructed before both side wall parts 210, so it is possible to stand on its own during construction. In order to do this, the front part B is reinforced using the reinforcing material 111 in order to improve the independence and verticality of the backfill 110 and to construct the buffer part 120 together.

This backfill 110 is constructed with a certain height (H) while laying and compacting cement-treated soil or gravel at a certain height, and each time lamination, a reinforcing material (111, geogrid for ground reinforcement, etc.) By laying a plurality of stacked backfill 110 is to be integrated in the top and bottom.

Accordingly, the backfill 110 is vertically self-reliant toward the rear surface (A) of both side wall parts 210, but the bottom width vertically independent from the bottom surface of both side wall parts 210 to the top plate 220 is It is constructed in the form of a trapezoidal cross-section larger than the width of the upper surface, and the reinforcement 111 is also constructed in multiple layers, and it can be seen that the construction is being constructed so that the horizontal extension length becomes shorter toward the upper part in response to the applied earth pressure.

In addition, since it is cemented and is constrained with the side wall 140 to be described later, it is possible to effectively support the buffer unit 120 that absorbs deformation from the inside of the side wall. That is, the backfill 110 is integrated in the portion in contact with the side wall 140 , but the buffer part 120 to be described later is separated without being integrated, so that it is possible to effectively secure the lateral deformation of the buffer part 120 .

Next, the buffer part 120 is a space formed vertically between the backfill 110 and both side wall parts 210 of the bridge structure 200 and the back surface A of the upper plate 220, as shown in FIGS. 2a and 2b. It is formed in (S), but is formed to be located in the space (S) using the reference frame 130 so that it can be formed vertically together on the front part (B) of the backfill (110).

The buffer unit 120 absorbs the deformation of both side wall parts 210 due to the control load, temperature load, etc. of the vehicle including the train transmitted from both side wall parts 210 and the top plate 220 of the bridge structure 200 . Meanwhile, both side wall portions of the bridge structure 200 by absorbing deformation caused by horizontal earth pressure and seismic load acting on both side wall portions 210 and the upper plate 220 of the bridge structure 200 by the backfill 110 construction It serves to reduce the earth pressure and load borne by the 210 and the upper plate 220 to make the cross-sectional slimming possible.

The buffer unit 120 uses soil or gravel that does not use cement to be deformed by horizontal force and load, so that the constituent particles are bound to each other and do not act as a rigid body, and to absorb the expansion and contraction of the bridge structure. will do

That is, between the sidewall portions 210 of the bridge structure 200 and the backside of the top plate 220 and the backfill 110 , the buffer portion 120 that is a vertical layer of soil or gravel is formed to form both sidewalls of the bridge structure 200 . The part 210 and the upper plate 220 are designed to absorb the stretch on the back side.

In addition, since it is not treated with cement and is accommodated inside the side wall without being constrained to each other with the side wall 140 to be described later, effective absorption is possible even when the lateral deformation of the bridge structure 200 occurs.

Therefore, unlike the present invention, if the buffer part 120 is not provided, both side wall parts 210 and the upper plate 220 of the bridge structure 200 that resist the expansion and contraction must be constructed as in the prior art. Since the cross-sectional area increases, the construction cost and quality control of the bridge structure become difficult. In the present invention, the buffer part 120 is constructed together with the backfill 110 to solve this problem.

In addition, the reinforcing material 111 is installed on the stacked upper surface of the backfill 110 and the bottom surface of the buffer 120, as shown in FIG. 2b, while both side wall portions 210 and the upper plate 220 of the bridge structure 200. The backfill 110 and the buffer part 120 are arranged in a U shape to surround the sides while extending upward, and the arrangement position of the backfill 110, the buffer part 120 and the reinforcing material 111 is The reference frame 130 is used to increase workability by displaying in advance.

Accordingly, the frame of reference 130 is connected to both side wall portions 210 of the bridge structure 200 and the inner reinforcing bars 230 of the upper plate 220, as shown in FIGS. 2A and 2B, and the horizontal connecting material 240 exposed to the outside. ) connected to the L-shaped reinforcing bar network, the vertical part is in contact with both side wall parts 210 and the back surface of the top plate 220, and the horizontal part is installed in such a way that it is extended toward the buffer part 120. .

After laying the reinforcing material 111 on the upper surface based on the horizontal part, and stacking the buffer part 120, the backfill 110 is also laminated together, and the backfill 110 and the buffer part 120 based on the vertical part. ) so that the reinforcing material 111 extends horizontally on the upper surface of the buffer unit 120 by wrapping the side surface, so that it can be installed as a U-shaped reinforcing material.

This frame of reference 130 is used in constructing the backfill 110, the buffer part 120, and the reinforcement 111 of the first layer on both side wall parts 210 and the top plate 220 of the bridge structure 200. It is installed in multiple layers, and the one manufactured in the form as shown in FIG. 1D is used.

Next, the sidewall 140 is, as shown in FIGS. 2A and 2B, so that the backfill 110 and the buffer part 120 are in contact with both sides while the backfill 110 and the buffer part 120 are accommodated inside. formed by a wall that As a concrete vertical wall that serves to surround the structure connection part 100, it is integrated with the backfill 110 and is separated from the buffer part 120 so that the buffer part 120 is longitudinal and lateral of the bridge structure 200. It plays a role in effectively absorbing directional deformation.

In particular, the side wall 140 extends to the outside of the rear surface of the side wall portion 210 and the upper plate 220 so that the position is set using a side wall connecting member 141 such as an L-shaped steel, so that stable vertical construction is possible. it can be seen that

This makes it possible to construct the stable structure connection part 100 by acting as a reinforcing means in the case of an impact caused by an unexpected earthquake load, etc.

[ Construction method of structure connection part capable of reducing deformation absorption settlement of the present invention ]

3a and 3b show a construction flow diagram of the construction method of the structure connection part 100 capable of reducing the strain absorption settlement of the present invention.

The structure connection part 100 construction is, as shown in FIG. 3a, the backfill 110, the buffer part 120, and the side wall 140 while accommodating the subsidence generated by the pre-construction, the side wall part 210 is the reference frame 130. The post-construction to be connected to the buffer unit 120 is carried out by using it, and the construction is performed in a manner of constructing the upper plate 220 between the upper inner side of the side wall unit 210 .

At this time, the side wall 140 is constructed by separating it from the buffer unit 120 and integrating it with the backfill 110 .

Accordingly, according to FIG. 3A, first, while laminating the reinforcement material 111 using the reference frame 130, the backfill 110 is also laminated together with the buffer unit 120, and the final backfill 110 has a packaging layer on the upper surface. It can be seen that the pre-construction is being carried out so that this is formed. The backfill backside will also be constructed as a fill layer.

Accordingly, the upper surface of the pavement layer is made to have the same height as the upper surface of the upper plate 220, and is connected to the inner reinforcing bars 230 of both side wall parts 210 and between the side wall part 210 and the upper plate 220, the rear surface (A). The buffer part 120 and the side wall part 210 are integrated with each other in such a way that they are connected using the horizontal connector 240 exposed to the space S formed vertically on the The unit 210 is integrally constructed between the upper and inner sides.

Accordingly, the side plate 140, the side wall portion 210, and the top plate 220 are united with each other by using the side wall connecting material 141.

As a result, as shown in FIG. 3b , when the bridge structure 200 is finally completed, when deformation (extension) occurs in the longitudinal and lateral directions due to the temperature load, vehicle load, etc. of the bridge structure 200, it is absorbed by the buffer unit 120 And, the subsidence of the structure connection part 100 can also be reduced through the reinforcing material 111 by the buffer part and backfilling.

As a result, it can be seen that the bridge structure 200 is not equipped with an expansion joint device and a bridge support, so that the cross-section of the bridge structure 200, the pile construction of the side wall part 210, and the cross-section slimming are possible. there is.

In particular, even if the deformation (contraction) is increased as the span length between the both side wall parts 210 increases, it is possible to reduce the construction cost by increasing the cross-sectional efficiency of the side wall part 210 and the top plate 220, especially the trial braking load by the railroad car. It is also possible to effectively manage the new construction.

In addition, stable construction management is possible by connecting the side wall 140 and the side wall part 210 while preventing the longitudinal and lateral deformation of the buffer part 120 from being otherwise constrained by separation from the side wall 140 . will do
