着対象などによって適宜設定できる。The adhesive 4 may be applied on the metal foil 2 by extruding the molten resin into a film using an extruder and continuously laminating it on the metal foil 2 on which the glass cloth 3 has been previously laminated. A resin dissolved in a solvent may be applied, and the thickness of the adhesive 4 can be appropriately set depending on the purpose of use, the object to be bonded, etc.
次に以上の接着テープ１を用いた遮水シートの接着方法
を第２図を参照して説明する。Next, a method of adhering a water-blocking sheet using the adhesive tape 1 described above will be explained with reference to FIG. 2.
なお、図における各遮水シート１０は、軟質塩ビ、ポリ

着したもので、規格に応じた定尺寸法に形成されている
。In addition, each water-shielding sheet 10 in the figure has a felt 14 and a nonwoven fabric 16 laminated and bonded to the upper surface of a water-shielding sheet main body 12 made of a synthetic polymer sheet such as soft PVC, polyethylene, polypropylene, or vinyl acetate-polyethylene copolymer. It is formed to a standard size according to the standard.
そして、両遮水シート１０の隣り合う末端突合わせ部１
０ａの裏面に、両者にまたがるようにして接着テープ１
の幅を合せて突合わせ部１０ａの長平方向に沿って法面
すなどの地表面に敷設する。Then, the adjacent end abutting portions 1 of both water-shielding sheets 10
Place adhesive tape 1 on the back side of 0a, spanning both sides.
They are laid on the ground surface, such as a slope, along the longitudinal direction of the butt portion 10a with the same width.
このセツティング終了の後、突合わせ部１０ａの上部に
高周波誘導加熱装置１８を設置し、重力を加えつつ紙面
と直交する方向、すなわち突合わせ部１０ａの長手方向
に移動させ、高周波誘導加熱する。この加熱装置１８は
市販されているもので、小型軽量で移動性に富む装置で
ある。After this setting is completed, a high-frequency induction heating device 18 is installed above the abutting portion 10a, and is moved in a direction perpendicular to the plane of the paper, that is, in the longitudinal direction of the abutting portion 10a, while applying gravity to perform high-frequency induction heating. This heating device 18 is commercially available, and is a small, lightweight, and highly mobile device.
この加熱により、加熱対象である金属Ｗ３２は発熱し、
この発熱によってその上部の熱融着性樹脂４は遮水シー
′ト本体１２の下面に融着する。Due to this heating, the metal W32 to be heated generates heat,
Due to this heat generation, the upper heat-fusible resin 4 is fused to the lower surface of the water-shielding sheet main body 12.
すなわち、前記遮水シート１０のフェルト１４は断熱性
があり、熱を通しにくいが、このように高周波誘導加熱
を行うことで、金属箔２側が発熱し、これの熱によって
樹脂４を間接的に加熱溶融させる。That is, the felt 14 of the water-shielding sheet 10 has a heat insulating property and does not allow heat to pass through easily, but by performing high-frequency induction heating in this way, the metal foil 2 side generates heat, and the heat indirectly causes the resin 4 to heat up. Heat and melt.
溶融した樹脂４は、装置１８の重量によって突合わせ部
１０ａの下面のシート本体１２に接着し、この状態で装
置１８での加熱後、冷却固化し、これによってシート本
体１２に対する接着を完了する。The molten resin 4 adheres to the sheet body 12 on the lower surface of the butt portion 10a due to the weight of the device 18, and in this state, after being heated by the device 18, it cools and solidifies, thereby completing the adhesion to the sheet body 12.
したがって、装置１８を駆動しつつ順次突合わせ部１０
ａに沿って移動させることによって移動速度に応じて接
着されることになるのであり、施工時間が短時間で済む
ことになる。Therefore, while driving the device 18, the abutting portions 10
By moving it along the line a, it will be bonded according to the moving speed, and the construction time will be shortened.
以上の施工によって突合わせ部１０ａの下面に沿って両
遮水シート１０にまたがった状態で接着テープ１が水密
状態に接着され、この部分の遮水性を保持する。By the above-described construction, the adhesive tape 1 is adhered in a watertight state along the lower surface of the butt portion 10a, spanning both water-shielding sheets 10, and maintains the water-shielding property of this portion.
その後、第３図の従来例と同じく遮水シート１０上に連
節ブロックＣが敷き詰められるが、突合わせ部１０ａは
平坦状となっているので、連節ブロックＣが擦れて破損
したり、捲れ上がるなどの弊害も生じない。Thereafter, the articulated blocks C are spread over the water-shielding sheet 10 in the same way as the conventional example shown in FIG. There are no adverse effects such as rising.
（発明の効果）
以上実施例によって詳細に説明したように、この発明に
よる土木作業用遮水シートおよびその連結方法によれば
、以下の利点がある。(Effects of the Invention) As described above in detail using the embodiments, the water-shielding sheet for civil engineering work and its connection method according to the present invention has the following advantages.
まず、この発明では、高周波遊動加熱装置を遮水シート
同士の突合わせ部の上面に沿って押し当つつ移動するこ
とによって順次突合わ廿部は接着テープを介して迅速に
接着されるため、施工性が良好である。First, in this invention, by moving the high-frequency floating heating device while pressing it along the top surface of the butt portions of the water-shielding sheets, the butt portions are quickly bonded via adhesive tape, so that the construction is easy. Good properties.
接着後は金属箔の遮水性によって両シート同士の突合わ
せ部は遮水性を保持する。また、シート同士は重ねてい
ないので平滑であり、連節ブロックの敷き詰めの際の障
害とならない。After adhesion, the butt portion of both sheets maintains its water-shielding properties due to the water-shielding properties of the metal foil. In addition, since the sheets are not overlapped, they are smooth and do not become an obstacle when laying the articulated blocks.
したがって、遮水シートを複数枚突き合わせた状態で法
面、その曲進水性の要求される地盤面に敷き詰めたとし
ても、その突合わせ部分の遮水性が低下したり洗堀され
るなどの惧れがなくなり、このため、規格化された一定
寸法の遮水シートを用いることができる。Therefore, even if multiple sheets of water-shielding sheets are butted against each other and laid on a slope or on a ground surface that requires curved launching properties, there is a risk that the water-shielding properties of the butted portions will decrease or the sheets will be scoured. Therefore, it is possible to use a standardized water-blocking sheet with a certain size.
