要旨とするものである。This invention for the above-mentioned purpose is a mountain stop construction method in which a raised wall is provided with a cross member on the inside of a retaining wall, and the corner is reinforced with flint, in which a PS steel wire is stretched inside the raised wall, and
The gist is to provide a jack that tensions the PS steel wire in the horizontal direction in the center of the abdominal lift, and to use the PS steel wire as a reaction force to apply a reverse reaction force to the abdominal lift, thereby reducing the lateral pressure on the abdominal lift. It is something.

れている。This receiving member 7 is formed by forming a semicircular half 73 of a metal fitting 72 having an insertion hole 71 in the center.
is housed inside the base metal fitting 8 integrated with the fixing metal fitting 4 with the half part 73 facing outward, and the half part 73 faces the vertical groove 9 of the wall part 5 so as to be freely rotatable in the horizontal direction. It is set in.

などのジヤツキ１２が外向きに取付けである。Both ends of the PS steel wire 6 are inserted through the receiving member 7 and stretched inside the rib cage 2 . Further, a base metal fitting 10 is attached to the inside of the central portion of the breech 2, and a jack 12 such as a journal jack or a hydraulic jack is attached to the base metal fitting 10, together with a receiving metal fitting 11, facing outward.

ている。The central part of the PS steel wire 6 is not hung on the head 12a of the jack 120, and the extension of the jack 12 tensions the PS steel wire 6 like a string, and acts as a reaction force, causing abdominal tension. A reverse reaction force is applied to the center of 3.

腹起２の支持スパンを広げることができる。The reverse reaction force generated by the PS steel wire 6 and jack 12 can be arbitrarily set according to the magnitude of lateral pressure due to earth pressure, water pressure, etc. acting on the retaining wall 1, and thereby The bending moment and shear force of 2 are reduced,
The support span of the abdominal stand 2 can be expanded.

なる。Figure 4 is an explanatory diagram of the bending moment. Assuming that the bending moment due to the design side pressure is +M1, the bending moment knee due to the center jack reaction force M2, and the eccentric bending moment knee due to the tension of the PS steel wire M3, the resultant moment is MΦ =M - (M2+M3) M end = M3, and the bending moment applied to the breech 2 becomes small.

の能率も向上するなどの特長を有する。As described above, this invention uses the PS steel wire stretched inside the ventricle as a reaction force to apply a reverse reaction force to the central part of the ventricle using jacks, thereby reducing the bending moment and shearing force of the ventricle due to lateral pressure. Because of this, it is possible to widen the support span of the ventricle and omit the cutting burr, thereby reducing the cost of locking and root cutting. In addition, the support span of the uprise can be designed according to the level of lateral pressure and the planar scale of the excavated ground, and a large internal space can be secured, which improves the efficiency of underground construction.
