Description of the Related Art Conventionally, for example, as shown in FIG. 16, in order to construct an underground structure for forming a passage or the like in a direction intersecting the road in the ground under a road, as shown in FIG. After excavating vertical shafts B and C on both sides of road A, a large number of steel rectangular pipes 21 with strip-shaped edging plates 22 placed on the upper surface are compatible. A pipe roof P having a width substantially equal to the width of the upper floor is formed by press-fitting in parallel to at least a portion corresponding to the cross-sectional position of the upper floor of the structure, and then an underground structure is formed on the rear end surface of the pipe roof P. The front end face of the upper floor of the object F is brought into contact with the edging plate.
Replacing the pipe row of the pipe roof P with the underground structure F by advancing the underground structure F along the lower surface of the strip-shaped edging plate 22 while excavating the ground in front while fixing 22. Is being done.

によって押し進めることが困難となる。In such a method of constructing an underground structure, a plurality of rectangular pipes 21 of the same size and the same shape, each having a strip-shaped edging plate 22 placed on the upper surface thereof, are embedded in a laterally juxtaposed state in a pipe roof. When the width of the pipe roof P becomes smaller than the width of the upper floor portion f of the underground structure F in the case of forming P, both ends of the upper floor portion f of the underground structure F protrude from the pipe roof P and the resistance to the ground is increased. Becomes larger and larger, it becomes difficult to push the rectangular pipes 1 on both ends of the pipe roof P by advancing the underground structure F.

A small rectangular pipe 31 is used as a part of the rectangular pipe 21 adjacent to the narrow strip-shaped edging plate 32 placed on the upper surface thereof,
The strip-shaped plates 22 on the 21 are interposed so as to be flush with each other.

た。However, in such a width adjustment of the pipe roof P, since a small rectangular pipe 31 has to be used separately, not only the structure becomes complicated but also the width adjustment is performed with high accuracy. Moreover, in order to press-fit and bury the small rectangular pipe 31 in the ground, the rectangular pipe 21 of the same size and the same shape is press-fitted and inserted into the pipe 21 at the time of burial to excavate the ground. However, it is not possible to use a drilling tool such as a screw auger, and it is necessary to separately use a drilling tool having a small diameter, which not only increases the construction cost but also reduces the work efficiency.

るものである。Further, in the work of press-fitting and burying a large number of rectangular pipes 21 in parallel one after another, it takes a lot of time and labor and the construction cost becomes high, and after the pipe roof P is constructed, When replacing the pipe row with the underground structure F, pushing the pipe row with the front end face of the underground structure F requires a large propulsion force, which causes a problem such as large-scale construction. An object of the present invention is to provide a pipe roof and a method for constructing the pipe roof that can completely eliminate such problems.

A steel circular pipe body 1'having a diameter larger than the wall thickness of the upper floor F1 or the side wall portion F2 may be adopted, and in this case, a traction member 5'made of a steel rod is provided on the upper surface of the circular pipe body 1 '. After being buried in the above-mentioned cross-sectional position of the planned underground structure F between the compatible pits B and C without placing the narrow strip edging plate 3 in a state of being installed in close proximity to each other and in parallel, the wide strip edging is performed. Both sides of the front end of the plate 2 are integrated by welding to the rear ends of the traction members 5 ', 5'of the adjacent pipe bodies, and in the same manner as above, the traction member 5'is pulled out to the reaching shaft C side and a wide strip edge is cut. The plate 2 is embedded between the pipe bodies 1'and 1'in a erected state. At this time, the wide side strips 2 and 2 adjacent to each other are buried so that the opposite side faces thereof are in contact with each other so that the upper ground does not move when the pipe body 1 ′ and the underground structure F are replaced.

推進、埋設させることができるものである。After burying the pipe body, the front end of a wide strip-shaped edging plate having a substantially equal width between adjacent pipe bodies on the starting shaft side is integrally fixed to the rear end of the traction member, and on the reaching shaft side. A method of propelling or burying a wide strip-shaped edging plate along the pipe in the ground between adjacent pipe bodies while the pipe body is left in the ground by pulling the towing material in the pulling direction with a jack or the like. Therefore, it is possible to bury the wide strip edge plate accurately and efficiently in the ground between the pipes, and the wide strip edge plate divides the planned underground structure and the surrounding ground into the underground structure. When burying an object, the underground structure can be propelled and buried smoothly along the wide strip edge plate while surely preventing movement of the ground around it by the wide strip edge plate.
