Description

[0001] The present invention relates to an initial digging messenger shield pannel for an underground tunnel,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a leading bending panel for constructing an underground tunnel.

Generally, in the case of constructing an underground tunnel, an arbitrary tunnel section type is set, and a large hole is appropriately drilled in the axial direction of the tunnel on the upper and side surfaces thereof.

At this time, if the upper ground slope soil is relatively soft ground, the connection action between the upper slurry particles can not be expected and the voltage will be applied to the tunnel type upper surface depending on the total weight of the upper ground slope weight, and if the ground surface is railway, And even if there is a structure immediately above it, the subsidence or collapse of the ground slope will occur in that part, which will interfere with the construction work and cause serious problems in major urban functions.

The Messer Shield method, which is used to excavate the tunnel surface and the underground, is a method of arranging the shields (seam plates) in parallel on the support material (guard) Hydraulic machine), one at a time, while the excavation is carried out, while the excavation face behind the shield is covered with a soil board and supported by the support material.

1 to 3, an oscillating pedestal 2 made in the shape of a tunnel is installed in front of a tunnel 1 to construct a tunnel, (5) are installed at predetermined intervals in a space formed by pushing forward and forward the front bulging panel (3) having a sharp tip at the top thereof with a hydraulic jack, and the inside of the tunnel A supporting plate 6 of an appropriate length is provided at the rear end of the front bulging panel 3 which has been advanced by press-fitting and the connecting portion 7 and the supporting plate 6`, which form the short- The connecting portion 7 of the connecting shaft 8 and the bottom portion of the supporting plate 6 of the front turbocharging panel 3 are connected to the front turbocharging panel 3, The hydraulic jack is pushed forward in a range where it is not separated, and the next connecting baffle panel 8 is moved apart The panel 9 is press-fitted in advance and brought into contact with the panel 3 which is pivoted at the front end and another connecting pivot panel 8 'is connected at the rear end thereof. 5 'are installed at regular intervals to penetrate a tunnel having a desired length and then the front piercing panel 3 and the oscillating pedestal 2 are demolished and the connecting piercing panels 8 and 8' ) 5 'are embedded in the lining concrete 10 so that the tunnel is constructed.

Here, the front bending panel 3 and the connecting bending panel 8 (8 ') are provided with a front bending panel 3 having a drilled propelling hole 11' (11 ') for mounting a hydraulic jack at the bottom, A connecting portion 7 having a thickness and a length of a shorting portion S of the supporting plate 6 is formed at both ends of the connecting and bending panels 8 and 8 ' And a supporting plate 6 'to which the connecting portion 7 of the panel 8' is closely contacted is formed so as to be continuously and coplanarly connected to one end of the upper surface and the downward bent portion 12 and the upward bent portion 12 ' (13) are formed respectively and the upwardly bent portions (13) are engaged with the downwardly bent portions (12) so as to be continuously connected in the lateral direction. In this case, the rear end of the head portion 36 is constituted by a head top plate 37, a triangular plate 39 and a head lower plate 38 in the form of a rectangular frame 36a, And the ends of the square frame 36a and the main body panel 30 are integrally welded to each other in a state of a vertical plane.

A rear end of the main body panel 30 integrally forms a plate-shaped support plate 6, in which a part of the support plate 6 overlaps the circular tube 34, and the non-overlapping portion is projected backward. 4, a reinforcing frame 63 having a rectangular shape is placed between the upper plate 61 and the lower plate 62 and a reinforcing rib 64 is provided in the reinforcing frame 63 in the longitudinal direction, .

After the oscillation platform 2 is installed in front of the tunnel to be constructed with the panel having the above-described construction, the front pierced panels 3 are connected and arranged in the width direction, The surface finishing work 1 is excavated while press-fitting the work surface 1 with the hydraulic jack, and the work 5 (5 ') is successively formed in the space portion formed by the excavation work. However, since the head portion 36 and the body panel 30 are welded so as to form a vertical plane as shown in FIG. 5, the head portion 36 and the main body panel 30 may be cut off during the vertical load, There is a problem that the support plate 6 is bent at the main body panel 30 when the connection portion 7 of the connection and bending panel 8 which is overlapped with the support plate 6 is also subjected to a vertical load,

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems, and it is an object of the present invention to provide a head part top plate which is horizontally And the corresponding main body panel is formed with cutting grooves into which the elongated plate and the circular tube are fitted so that they are welded at the edges of the elongated plate and the cut groove and the rectangular frame excluding the elongated plate is welded to the tip of the main panel And to provide a leading bending panel for constructing an underground tunnel by reinforcing a vertical direction load by increasing a coupling force by perpendicularly joining a vertical plane and a horizontal plane.

It is a further object of the present invention to provide a method of manufacturing a steel pipe, in which a front end of a supporting plate attached to a rear end of a front pouring panel is welded to overlap with a circular pipe, and a supporting plate of overlapping portion is provided with a reinforcing reinforcing frame, And the auxiliary rib is longer than the overlapped portion of the circular tube so as to increase the vertical coupling strength between the coupled-coupled panel and the supporting plate.

To this end, the present invention relates to a bending tunnel for constructing an underground tunnel using a front bending panel and a connecting bending panel, wherein a front end of the main panel constituting the bending panel is overlapped with a head portion having a sharp- A support plate;
