Description

  The present invention relates to a method for constructing an underground structure such as a tunnel constructed under a road.

  As a method of constructing underground structures such as tunnels by burying a plurality of concrete boxes under a road, etc., there are, for example, an excavation method and a tunnel method. While excavating the ditch, the concrete box is suspended from the ground and buried in the excavation ditch.

  On the other hand, the shield method excavates the ground with a shield machine, suspends a concrete box from a vertical shaft, and embeds it sequentially in the excavation trench.

  The prior art is generally performed by those skilled in the art, and is not related to a known literature invention.

  The excavation method is not costly, but has an inconvenience that the upper traffic is greatly restricted because of the excavation.

  On the other hand, since the shield method is only the entrance to the shaft, the part that opens to the ground is almost free from upper traffic, but it is expensive.

  The present invention eliminates the inconvenience of the conventional example, and combines the open-cut method and the shield method, so that the upper traffic restriction can be reduced compared to the open-cut method, and the open-cut method is used in combination with the shield method. Further, the present invention provides a method for constructing an underground structure that can be constructed with zero soil covering and can improve the workability.

  The invention according to claim 1 is a construction method of an underground structure in which a plurality of boxes are continuously buried in a column in the basement, and a lining plate is installed from one end of the construction place toward the other end. While propelling, push the lower part of the unfolded box from the other end to the lower side of the lining board, and then push the box upper floor board to the specified position on the lower part of the box while pulling back the lining board. The gist is to let it be installed.

  According to the first aspect of the present invention, after the lining plate is installed to secure the upper traffic, the lower portion of the lining plate is excavated by the open shield method and the lower portion of the open box is formed here. After that, it was installed by sliding the box upper floor board on the lower part of the box in place of the lining board while pulling back the lining board. You can traffic on the top.

  Therefore, the traffic restriction can be minimized, and the earth covering can be reduced to 0, thereby improving the workability.

  The gist of the invention described in claim 2 is that the lower part of the box is propelled by excavating the lower part of the lining plate with an excavator disposed below the lining board to secure a propulsion space below the box. Is.

  According to the second aspect of the present invention, the space for propelling the lower part of the box is secured by excavating with an excavator disposed in the ground below the lining plate. It is possible to reduce the restriction of upper traffic without digging the excavation groove by the open-cut method.

  As described above, the construction method of the underground structure of the present invention is to install the lining plate while sliding the lining plate at the construction site, and after installing the lower part of the open box body below it, slide the lining plate. It is installed on the lower part of the box while sliding the box upper floor board to replace it while removing it. Boxes can be laid with traffic restrictions.

  Moreover, the earth covering can be reduced to 0, and the workability is improved.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view of a first step showing an embodiment of a construction method of an underground structure according to the present invention, FIG. 2 is a front view of the same, and the present invention is an open type concrete below a road 23 with vehicle traffic. This is a method for constructing underground structures such as tunnels using boxes.

  As a first step, as shown in FIGS. 1 and 2, a ground road 23 at a construction site is excavated by an excavation method using an excavator such as a backhoe 8, and a lining plate girder (rail) 1 is installed. In the figure, 2 is a PC plate, 3 is a crushed stone foundation, and 4 is a guide plate.

  Reference numeral 9 denotes a truck for carrying materials and the like, and a portion of the road 23 that is not excavated is secured as a travel path of the vehicle 11. Reference numeral 10 denotes a cone for displaying a traveling lane.

  As a second step, as shown in FIG. 3 and FIG. 4, the lining plate receiving girder 5 and the lining plate 6 are installed / assembled at a portion where there is no upper limit, and in FIG. While excavating, the bearing concrete 16 and the lining board propulsion jack 13 are installed on the left side shaft side in FIG. In the figure, reference numeral 12 denotes a dump truck for discharging excavated soil.

  Then, the assembled lining plate receiving girder 5 and lining plate 6 are pushed and pushed in the direction of the starting shaft by the lining plate propulsion jack 13 along the lining plate girder (rail) 1.

  In the figure, reference numeral 15 denotes a lining plate propulsion strut, which is appropriately disposed between the lining plate propulsion jack 13 and the bearing concrete 16.

  In this state, the top of the lining plate 6 is the travel path of the vehicle 11.

  In this way, after securing the traveling path of the vehicle 11, a start shaft is constructed as the third step, a main push jack 19 is disposed here, and the open shield machine 20 is directed from the start shaft side toward the reaching shaft. The excavator such as the backhoe 8 disposed in the open shield machine 20 is excavated to advance below the lining plate 6. In the figure, 17 is a belt conveyor for discharging excavated soil, and 18 is an overturning type trobucket.

  The box lower part 7a of the open type concrete box is suspended from the starting shaft in the excavated space by a crane 14 or the like, and pushed out by the main push jack 19 in the direction of the reaching shaft. During this time, the vehicle 11 travels on the lining plate 6.

  In a state where all of the box lower part 7a is propelled to the reach shaft side, as shown in FIG. 7 of the fourth step, the lining plate receiving girder 5 and the lining board 6 are supported by the box lower part 7a.

  In this fourth step, the lining plate propulsion struts 15 are removed by the crane 14, and the lining plate receiving girder 5 and the lining plate 6 are pulled back and removed to the reach shaft side by the lining plate propulsion jack 13, and at the same time, The upper floor board 7b is propelled from the start shaft side by the upper floor board propulsion jack 21 and pushed out. In this state, the box upper floor board 7b slides on the upper surface of the box lower part 7a and advances. Thereby, the lining board 6 is replaced with the box upper floor board 7b.

  After all the lining boards 6 have been replaced with the box upper floor board 7b and the box upper floor board 7b has been installed at a predetermined position, the box lower part 7a and the box upper floor board 7b are fastened by the PC steel rods 22 for vertical fastening. And build a tunnel that is an underground structure.

  FIG. 9 and FIG. 10 show the fifth step, and the underground structure in which the box upper floor board 7b is installed on the box lower part 7a in place of the lining board 6 as described above is the case of the box upper floor board 7b. Since the upper surface is located on the same plane as the surface of the road 23, the construction is performed with zero earth covering, and the workability is good. And the vehicle 11 will drive | work the upper surface of the box top floor board 7b.
