Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side wall structure using an earth retaining member and a method of constructing the same,

The present invention relates to a sidewall member using a retaining member and a method of constructing an underground structure using the same. More particularly, the present invention relates to a method of constructing a sidewall member using an earth retaining member, The present invention relates to a sidewall using a retaining member for constructing an upper slab by a steel pipe press-fitting method, and a method of constructing an underground structure using the sidewall member.

In order to maximize the utilization of the recently constructed infrastructure and to satisfy the demand of newly constructed social infrastructures, it is necessary to install the facilities such as traffic facilities such as railway and highway in operation, roads passing through under the main structure, .

The method of constructing the structures in the lower part of the traffic facilities or the main structures can be roughly divided into the open method and the non-open method.

Until the mid - 1980s, the installation method was mainly constructed by the disturbance caused by excavation and landfilling, which caused problems such as settlement of the ground even after the completion of the structure, which had a disadvantage of impeding the operation of the transportation facilities during the construction period.

Recently, non-installation methods have been mainly used in the case where sewer canal, underground roadway, tunnel structure, etc. should be installed across existing roads and railways. The STS construction method is applied to the construction of a steel pipe which is used in a steel pipe loop construction method for constructing an underground structure, Steel pipe loop structure and its steel pipe loop method "(Patent No. 0569703). That is, as shown in FIG. 1A,

The steel pipe 32 used for the upper slab and both side walls of the underground structure is attached to one side of the steel pipe 32 so that the first flange 31 is vertically spaced apart and the second flange 35 are vertically spaced apart.

A hooking collar 37 is formed on one side of the center of the steel pipe 32, and a T-shaped latch 33 is attached to the other side of the center.

This steel pipe 32 is press-fitted into the ground by using a press-fitting means,

So that the reinforcing steel bar 39a penetrates through the through hole 34 of the adjacent steel pipe 32 and is fastened with the fixing plate screw 39b.

Thereafter, mortar or concrete is filled in the steel pipe 32 to form an underground structure of a ramen structure which is integrated in a continuous and longitudinal direction.

Unlike the pipe loop method in which a transverse girder is additionally provided on the inside of the conventional composite slab type ground structure, a lateral girder is unnecessary, which is superior in terms of workability and safety.

However, the neighboring steel pipes must be continuously installed by the guide (the hooking hooks 37 and the T-shaped hooks 33), so that the number of the steel pipes to be installed is increased and the cost is increased. There is a problem that the manufacturing becomes complicated due to the additional flange.

The NTR method (Japanese Patent No. 10505301, Japanese Patent No. 10505301, Japanese Patent Application Laid-Open No. 10505301, and Japanese Patent Application Laid-Open No. 10505301), in which steel pipes are press- Structure for installation of underground tunnels).

That is, as shown in FIG. 1B, in the conventional NTR method, the circular steel pipes 30 are adjacent to each other and are press-fitted in the vertical direction so as to conform to the shape of an underground structure, 40, and grouting 70, respectively,

The upper and lower connecting steel plates 41 and 42 are welded and welded to the upper and lower ends of the incision portion so as to extend in the longitudinal direction,

A reinforcing bar (43) is provided at the center between the connecting steel plates so that the upper and lower connecting steel plates do not sag or sink due to the upper earth pressure,

And a steel pipe structure and a concrete (C) are placed in the inside of the steel pipe to form the steel pipe structure.

The NTR method is characterized in that an underground structure is constructed by cutting and reinforcing the side portions so that the steel vessel side walls communicate with each other in the press-fitted steel pipe,

There is a risk that the overburden between the adjacent steel pipes is relaxed in the process of side incision of the steel pipe so that the subsidence occurs or collapses and the connecting steel plates 41 and 42 are respectively welded and connected to the steel pipe incision along with the excavation of the side, 43) is repeated, so that the process becomes difficult.

Further, when the longitudinally arranged steel pipe is separated from the adjacent steel pipe too far, it is difficult to cut the side portion and install the connecting steel plate. Therefore, the steel pipe must be installed as close as possible to the steel pipe, The installation amount of the connecting plate is increased as much as the number of the connecting plates.

In addition, the earth leakage prevention plate 40 is used as a plate material sandwiched between outer circumferential surfaces of adjacent steel pipes so that the overburden between adjacent steel pipes spaced apart is relaxed so that settlement does not occur, but also does not act as a part of the underground structure It was nothing but a kind of temporary soil protection plate.

In order to solve the above-mentioned problems, the side wall part acting on the side earth pressure is constructed differently from the upper slab. The upper slab of the underground structure is constructed by the steel pipe indentation method such as STS method, And the side wall steel pipes are spaced apart from each other in parallel by vertically and horizontally inserting the side wall steel pipes so that the spaced apart portions of the side wall steel pipes are provided with a counter support plate having a thumb pile function in the longitudinal direction of the side wall steel pipe, It is an object of the present invention to provide a sidewall using an earth retaining member which is simple and easy to manufacture and a method for constructing an underground structure using the same, We will do it.

Another problem to be solved by the present invention is that when the ground of the sidewall as well as the sidewall is hard ground such as weathered rock or soft rock, it is difficult to press the sidewall steel pipe, so that the sidewall steel pipes are press- The present invention provides a sidewall using a retaining member and a method of constructing an underground structure using the same, which can reduce construction cost by reducing the number of side wall steel pipes for sidewall construction.

According to an aspect of the present invention,

First, the underground structure is basically constructed by the steel pipe indentation method. In the constant slab of the underground structure, the upper slab portion of the temporary structure in which the load is applied in the vertical direction is formed by a composite slab type (STS method) Side wall steel tubes spaced vertically and parallelly are provided, and the spaced apart portions between the side wall steel pipes are provided with a soil plate support having a function of a thumb pile so as to be vertically spaced apart in the vertical direction, After fixing, the earth retaining member including the earth plate is inserted and installed between the soil plate supports.

Second, the fixing of the side wall steel pipe and the earth plate support is performed by pouring concrete into the pipe of the side wall steel pipe including the slab steel pipe for constructing the upper slab so that the concrete is hardened and hardened, and the earth pipe member is used as the earth retaining member. Shotcrete may be used.

Third, a method of installing the dust-collecting plate support in the side-wall steel pipe may be assembled while inserting the support segment carried in the inside of the side-wall steel pipe into the support-through hole formed in the upper surface and the lower surface of the side-wall steel pipe in the vertical direction .

These support segment segments are connected to each other by welding or bolts, and are continuous up and down. It is also possible to sufficiently fasten both end portions of the support segment in the side wall steel pipe without continuing them.

In the present invention, the upper slab of the underground structure uses a pipe loop method such as the conventional UPRS method in which the steel pipe is continuously installed, or a composite slab type (STS method) in which the steel pipe is continuous, and the side wall body is divided into upper and lower The side wall steel pipes are arranged in a spaced-apart relationship between the upper and the lower side in a spaced-apart relationship, and a soil plate support base is vertically installed in the spaced apart spaces. In addition, a soil retaining member (earth plate, etc.) And it is possible to construct an economical underground structure.

Further, in the present invention, the joint between the upper and lower side walls of the side wall steel pipe is strengthened by the concrete in the side wall steel pipe intersecting the soil plate support and the side wall steel pipe with the function of the thumb pile, and the lattice structure is formed. .

In other words, the earth plate support of the thumb pile function of the present invention is formed such that the joint portions intersecting with the side wall steel tubes spaced apart from each other in parallel are strong in the side wall steel pipe and distribute load to each other, (Functioning as a structural body).

Further, in the case of hard ground such as weathered rock which is difficult to press the side walls as well as the gravels, the number of press-in side wall steel pipes to be press-fitted is significantly reduced, and workability and economical efficiency are improved.

As a result, in the present invention, the lateral earth pressure is supported during the inner excavation of the underground structure by the side wall steel pipe provided with the earth retaining member in the ground, so that the number of the side wall steel pipe is minimized, The number of the steel pipe press-fitting can be greatly reduced, so that the input material can be reduced and the workability can be improved.

In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

[Siding member using an earth retaining member]

2B is a construction sectional view of the upper slab, FIG. 2C is a sectional view of the earth slab member and the side wall steel pipe, Fig.

First, as shown in FIG. 2A, the upper slab 100 is constructed by a steel pipe indentation method (STS method), and the conventional PRS method or UPRS method can be applied.

That is, the upper slab 100 is sequentially press-fitted so that the side portions of the slab steel pipe 110 are coupled to each other.

2B, the first flange 111 is attached to one side of the slab steel pipe 110 so as to be vertically spaced apart from the first flange 111, and the slab steel pipe 110 And the second flange 112 is attached to the side face so as to be vertically spaced.

A hooking hook 113 is formed at the center of one side (right side) of the slab steel pipe 110, and a T-shaped latch 114 is attached at the center of the other side (left side).

The slab steel pipe 110 is first press-fitted into the ground using a press-fitting means and a T-shaped latch 114 of another slab steel pipe 110 is inserted into the hook-and-groove fastener 113 of the press-fitted slab steel pipe 110 So that the side portion of the steel pipe comes into contact with the steel pipe.

So that the reinforcing bar 116 penetrates through the through hole 115 of the adjacent slab steel pipe 110 and is engaged with the fixing plate 117.

Thereafter, the concrete is filled in the slab steel pipe 110, so that the slab steel pipes are combined with each other by the reinforcing steel bars to construct the upper slab 100. Accordingly, the installation of the lateral girders installed in the conventional pipe- It becomes unnecessary.

2A, the slab steel pipe 110 located at both ends is located at the upper edge of the underground structure A, and the slab steel pipe 110 located at the upper edge of the underground structure A is connected to the side wall steel pipe 210, It is necessary to install the support segment in the slab steel pipe 110. Therefore, a steel pipe having a large diameter such as the side wall steel pipe 210 is used, and the first flange 111 is attached to the other side only And a slab steel pipe 110 having a T-shaped latch 114 formed at the center of one side thereof is used.

The sidewall 200 using the earth retaining member 220 includes the outermost outermost slab steel pipe 110 of the upper slab 100 constructed as shown in FIG. 2A, and the slab steel pipe 110 downward Walled steel pipe 210 spaced apart from each other in parallel and the earth retaining member 200.

The sidewall steel pipe 210 may be formed by using a circular steel pipe and press-fitting the slab steel pipe 110 located at both ends of the upper slab 100 downward.

The spacing distance is not otherwise specified, but may be determined in consideration of the diameter of the side wall steel pipe 210 considering the characteristics of the surrounding ground and the working space.

That is, the sidewall steel pipe 210 of the present invention extends in the longitudinal direction and is spaced apart from the upper and the lower ends of the steel pipe 210. It is noted that the soil retaining plate 220 is installed between the upper and lower sidewall steel pipes 210, .

The soil plate support 221 may be a steel frame member or the like.

That is, the soil plate support 221 is characterized in that the side wall steel pipe 210 penetrates the side wall steel pipe 210 vertically so that the side wall steel pipe 210 and the soil plate support 221 are strong and act as a support structure in a lattice form.

That is, the soil plate support 221 vertically penetrates the side wall steel pipe 210 installed vertically and in parallel, and the concrete is filled in the side wall steel pipe, so that the side wall steel pipe 210 and the soil plate support 221 are tightly And the load is distributed to each other.

The side wall steel pipes 210 spaced apart from each other by the earth plate support 221 are coupled to each other to form a lattice frame structure to effectively resist the earth pressure acting on the side wall body 200,

Further, the ground relaxation due to the earth pressure acting as the spacing space between the side wall steel pipes 210 is minimized,

Furthermore, unlike the soil layer, the soil is hardly loosened due to the earth pressure as the spaced space.

The soil plate 222 is installed so as to extend in the longitudinal direction in parallel with the excavation of the soil during excavation of the internal ground formed by the slab steel pipe 110, the side wall steel pipe 210 and the soil plate support 221 between the soil plate supports 221 .

When wood, waste guide rails, steel plates, or the like is used as the soil plate 222, the soil plate may be installed in such a manner that both end portions are sandwiched between the soil plate supports. In the case of hard ground, shotcrete may be used instead of the soil plate .

When the sidewall member 220 and the sidewall member 210 are installed in this way, the number of the sidewall steel pipes 210 installed for installation of the sidewall 200 is remarkably reduced .

2C shows an example of a method of installing the soil plate supporter 221 in the side wall steel pipe 210 in the side wall steel pipe 210.

That is, it can be seen that the end slab steel pipe 110 and the side wall steel pipe 210 of the upper slab 100 are separated from each other by four as shown in FIG. 2C.

In order to install the soil plate support 221 in this manner, in order to install the soil plate support 221 on both end sides of the upper slab 100, Through holes 117 having a size such that the soil plate support 221 can be inserted downward can be formed at the bottoms of both end-portion slab steel pipes 110 of the upper slab 100,

Similarly, the support wall through holes 211 are formed in the respective side wall steel pipes 210 so that the support plate 221 can penetrate the upper and lower ends.

That is, a perforation hole (H) is formed in a spaced-apart space between the side wall steel pipes downwardly in both end-portion slab steel pipes (110) of the upper slab (100), and a support segment segment (221a) is formed on the bottom surface of the lowermost side- Is vertically fixed by welding or the like.

The earth plate support 221 is integrated with each other via the spacing space between the side wall steel pipes 210 and the side wall steel pipe 210 in such a manner that the other support member segment 221b is welded to the upper surface of the support member segment 221a previously installed .

The support segment segments 221a are inserted into the upper end surface of the support segment segment 221a through the holes of the spaced spaces between the side wall steel pipes 210 and the side wall steel pipe 210, .

2c, it is understood that the support segment segments 221c, 221d, 221e and 221f are further connected and integrated, and that the uppermost support segment segment 221f extends into the inside of the slab steel pipe 210. [ That is, it acts as a thumb pile.

Also, although not shown, both end portions of the support segment may be sufficiently embedded in the side wall steel pipe so as not to be connected to each other and to be continuous, or may be provided on the side wall steel pipe so as to be capable of installing the earth plate. This is because the support segments can be integrated with each other by the concrete C placed in the side wall steel pipe.

[Construction method of underground structure using sidewall member using earth retaining member]

3A, 3B, and 3C show a flowchart of a method of constructing an underground structure using a sidewall using a earth retaining member.

First, the upper slab 100 and the sidewall steel pipe 210 are press-fitted in consideration of the cross-sectional shape of the underground structure.

The upper slab 100 is a slab steel pipe 110 having one side and a first flange 111 that are vertically spaced apart and a second flange 112 that is vertically spaced apart from the other side, And the T-shaped latch 114 is inserted into the hook-and-loop fastener 113 so as to be guided so that the side surfaces of the steel pipe are press-fitted to be adjacent to each other.

At this time, the slab steel pipe 110 located at both ends of the upper slab 100 is installed at the upper edge portion of the underground structure because the support segment is installed inside the steel pipe. Therefore, the steel pipe having a large diameter like the side wall steel pipe 210 And the first flange 111 is mounted on the other side so as to be vertically spaced apart, and the slab steel pipe 110 having the T-shaped latch 114 formed at the center of the first flange 111 is press-fitted.

The sidewall steel pipe 210 is spaced downward from the slab steel pipe 110 located at both ends of the silver upper slab 100, 3A, it can be seen that the three side-wall steel pipes 210 are press-fitted.

Next, as shown in FIG. 3B, the reinforcing bars 116 are passed through the through holes 115 of the adjacent slab steel pipes 110 constituting the upper slab 100, and the screws 117, the fusing plate 117, Tighten.

In addition, the side wall steel pipe 210 is installed so as to pass upwardly and downwardly through the gap plate support 221 up and down in a spaced-apart space between the side wall steel pipe 210 and the side wall steel pipe 210 by using the above- Then, the concrete is filled in each of the slab steel pipe 110 and the side wall part side wall steel pipe 210 on the upper side and cures for a predetermined period.

Next, as shown in FIG. 3C, the inner soil formed by the upper slab 100 and the side wall steel pipe 210 is excavated from the upper part to the lower part for a certain period while sandwiching the soil plate 222 as described above between the soil plate supports 221, The space between the soil plate supports 221 spaced in the longitudinal direction is closed by the soil plate 222. [

When the soil plate 222 is installed between the side wall steel pipes 210 while the inner ground is excavated downward in the tunnel direction, the upper slab 100 and the side wall steel pipes 210 and the sidewall members 220, (200) is constructed and the internal ground remains in the excavation space (S) to construct the necessary structure.
