されている。Therefore, in this state, the three steel plates 13 are completely joined, forming a single wall plate 17 without any holes or gaps.
次に第１図Ｃに示すごとく前記溶接用足場１８を取り除
き、ターンバックル１０を回転せしめて、連結杆９およ
び治具８を介して両壁板１７を壁面７に接近させる。Next, as shown in FIG. 1C, the welding scaffold 18 is removed, the turnbuckle 10 is rotated, and both wall plates 17 are brought close to the wall surface 7 via the connecting rod 9 and jig 8.
この場合、壁板１７の裏面あるいは壁面７上にアンカー
ボルトなどを突設して壁板１７と壁面７との間に一定の
間隙αが生じるようにする。In this case, an anchor bolt or the like is provided protrudingly on the back surface of the wall plate 17 or on the wall surface 7 to create a certain gap α between the wall plate 17 and the wall surface 7.
また壁板１７と底板３とのつなぎ目２０を溶接する。Also, the joint 20 between the wall plate 17 and the bottom plate 3 is welded.
次にこの状態において壁板１７と壁面７との間の間隙α
内にコンクリート、モルタル等の充填材を充填し、該充
填材の養生固化後、第１図ｄに示すごとくナツト１６を
ねじ棒１４から外し、その後、ターンバックル１０を逆
回転せしめる。Next, in this state, the gap α between the wall plate 17 and the wall surface 7
A filler such as concrete or mortar is filled in the inside, and after the filler is cured and solidified, the nut 16 is removed from the threaded rod 14 as shown in FIG. 1d, and then the turnbuckle 10 is rotated in the opposite direction.
すると、連結杆９を介して治具８のみが壁面７から離間
し、壁板１７は壁面７に充填材を介して接着した状態で
残ることになる。Then, only the jig 8 is separated from the wall surface 7 via the connecting rod 9, and the wall plate 17 remains bonded to the wall surface 7 via the filler material.
次に第１図ｅに示すごとく台車４を矢印入方向に１ピツ
チだけ移動させて上記壁板１７に台車４の仕上部４ｂを
対向させ、該仕上部４ｂの足場２１を利用して壁板１７
表面に突出するねじ棒１４をグラインダーなどにより取
除き、壁板１７表面を仕上げる。Next, as shown in FIG. 1e, move the cart 4 by one pitch in the direction of the arrow so that the finished part 4b of the cart 4 faces the wall plate 17, and use the scaffolding 21 of the finished part 4b to 17
The threaded rod 14 protruding from the surface is removed using a grinder or the like to finish the surface of the wall board 17.
またこの仕上げ作業中に台車４の内張り部４ａにおいて
隣りの壁面７箇所に前述したのと同様にして壁板１７を
内張すし、台車４の移動方向においてつき合された壁板
１７のつぎ目２２を溶接して第５図に示すごとくトンネ
ル１の壁面７に沿つて多数の鋼板１３を内張すするもの
である。Also, during this finishing work, wall plates 17 are lined at seven adjacent wall surfaces in the inner lining portion 4a of the truck 4 in the same manner as described above, and the seams of the wall plates 17 that are butted in the direction of movement of the truck 4 are lined. 22 are welded and a large number of steel plates 13 are lined along the wall surface 7 of the tunnel 1 as shown in FIG.
上記実施例では、底板３を予め内張すしであるがトンネ
ル１の壁面７に壁板１７を内張すした後、底板３を内張
すするようにしてもよい。In the above embodiment, the bottom plate 3 is lined in advance, but the bottom plate 3 may be lined after the wall plate 17 is lined on the wall surface 7 of the tunnel 1.
また治具８をターンバックル１０により移動せしめるよ
うにしたが、これに限定されるわけではなく、シリンダ
装置等により治具８を移動させるようにしてもよい。Further, although the jig 8 is moved by the turnbuckle 10, the present invention is not limited to this, and the jig 8 may be moved by a cylinder device or the like.
以上述べたごとく本発明のトンネル等の内張り工法によ
れば、鋼板１３を一枚一枚内張りしていくのではなく、
複数の鋼板１３を予め溶接して大きな壁板１７を形成し
、それを内張すするものであるから内張り作業を能率よ
くおこなうことができ、寸法精度を高めることができる
ものである。As described above, according to the tunnel lining method of the present invention, instead of lining the steel plates 13 one by one,
Since a plurality of steel plates 13 are welded in advance to form a large wall plate 17 and then lined, the lining work can be carried out efficiently and dimensional accuracy can be improved.
また内張り作業と仕上作業とを同時進行によりおこなう
ことができ、工期の短縮化を図ることができる。In addition, lining work and finishing work can be done simultaneously, shortening the construction period.
