Description
本発明は、主として本発明は、廃棄物最終処分場、ラグーン、貯水池等の高精度の遮水施設に用いられる保護板の連結方法に関する。 The present invention mainly relates to a method for connecting protection plates used in high-precision water shielding facilities such as waste final disposal sites, lagoons, and reservoirs.
施設の斜面や底面に敷設される保護板は、通常、保護材料層の上下に外皮シートを配した三層構造になっており、また、隣接する保護板同士を連結する場合には、該連結部の信頼性等が要求される。 The protective plates laid on the slopes and bottom of the facility usually have a three-layer structure in which outer sheets are arranged above and below the protective material layer, and when connecting adjacent protective plates, the connection Part reliability is required.
そこで、保護板の連結方法としては、図８のように保護板ａの上側外皮シートｂ同士及び下側外皮シートｃ同士をそれぞれ溶着して袋状部を形成し、該袋状部内の充填用空所ｄに特定の一箇所から硬化型の保護材料を充填する方法や、図９のように下側外皮シートｃ同士を溶着して充填用空所ｅを形成し、該充填用空所ｅに硬化型の保護材料を充填した後に該充填部分を連結シートで覆って該連結シートの両側端部を上側外皮シートｂに溶着する方法が提案されていた。これらの方法によれば、上側外皮シートｂと下側外皮シートｃの間にポリウレタンなどの保護材料層が連結部分で途切れることがなく、連結部分が弱点になり難いという利点がある。 Therefore, as a method of connecting the protective plates, as shown in FIG. 8, the upper outer sheet b and the lower outer sheet c of the protective plate a are welded to form a bag-like portion, and the bag-like portion is filled. A method of filling the vacant space d with a curable protective material from a specific location, or welding the lower skin sheets c together as shown in FIG. A method has been proposed in which after the curable protective material is filled, the filling portion is covered with a connecting sheet, and both end portions of the connecting sheet are welded to the upper skin sheet b. According to these methods, there is an advantage that the protective material layer such as polyurethane is not interrupted between the upper skin sheet b and the lower skin sheet c at the connecting portion, and the connecting portion is unlikely to become a weak point.
しかしながら、前者の従来技術では、袋状部内の充填用空所は、保護材料層を送り込むための管路と同等とみなすことができることから、保護材料の圧送距離が長くなって保護材料の圧力損失が大きくなり、中間材料の充填設備が大型化するという問題があった。また、保護材料の充填圧力が不十分であると注入不足箇所が発生し、保護材料の充填圧力が過大であると、はらみ出し現象が生じ、連結部分での保護材料層を所定厚さに設定することが困難になり、材量費が高くなるという問題があった。 However, in the former prior art, the filling space in the bag-like portion can be regarded as equivalent to a pipe line for feeding the protective material layer, so that the pressure feeding distance of the protective material becomes longer and the pressure loss of the protective material There is a problem that the filling equipment for intermediate materials is enlarged. Insufficient filling pressure of the protective material may cause insufficient injection, and excessive filling pressure of the protective material may cause the phenomenon of protrusion and set the protective material layer at the connecting portion to a predetermined thickness. There was a problem that it was difficult to do and the material cost was high.
また、後者の従来技術は、充填用空所に保護材料を充填し終わった後に、上側外皮シート同士を溶着するので、保護材料の充填から連結シートを保護板に溶着するまでにタイムラグが生じ、その間に大気中の煤塵・粉塵等の異物が保護材料に混入して連結部分の品質が低下し、また、保護材料の硬化が進んだ段階で連結シートが溶着されるので、連結部分における保護材料層と連結シートとの一体性が欠けることが懸念されていた。 Moreover, since the latter prior art welds the upper skin sheets after filling the protective material in the filling space, there is a time lag from filling the protective material to welding the connecting sheet to the protective plate, In the meantime, foreign matter such as dust and dust in the atmosphere enters the protective material and the quality of the connection part deteriorates, and the connection sheet is welded when the protection material has hardened, so the protective material in the connection part There was concern about the lack of integrity between the layers and the connecting sheet.
本発明は、かかる問題を解決して保護板の連結部の品質を向上させ、また、連結部分での保護材料層と連結シートとの一体性を持たせることができ、しかも、作業効率を向上させることができる保護板の連結方法を提供する。 The present invention solves such a problem and improves the quality of the connecting portion of the protective plate, and can provide the integrity of the protective material layer and the connecting sheet at the connecting portion, and also improve the working efficiency.

本発明によれば、隣接する保護板と下側連結シートで囲まれる前記充填用空所を、その長さ方向に沿って上側連結シートを順次接続することで順次閉鎖する一方、未接合箇所の前記上側連結シートと前記保護板との間から前記充填用空所内に注入機の注出口を挿入して既接合箇所の前記充填用空所内に硬化型の保護材料を順次注入していくので、以下の効果が得られる。 According to the present invention, the filling space surrounded by the adjacent protective plate and the lower connection sheet is sequentially closed by sequentially connecting the upper connection sheet along its length direction, Since a spout of an injection machine is inserted into the filling space from between the upper connection sheet and the protective plate, and a curable protective material is sequentially injected into the filling space at the already joined location, The following effects are obtained.
充填用空所に充填された保護材料が大気に晒されることがなく、大気中の煤塵や粉塵等の異物が保護材料に混入するのを防止できる。また、注入機の注出口を移動させながら充填用空所に保護材料を充填していくことにより、保護材料の圧送距離が長くなって保護材料の圧力損失が大きくなるのを防止でき、保護材料の充填設備も小型化することができる。また、前記上側連結シートと前記保護板とを前記充填用空所の長さ方向に沿って順次接合し、既接合箇所の前記充填用空所内に硬化型の保護材料を順次注入していくので、保護材料層と上側連結シートとの一体性を高めることができる。このとき、上側連結シートは、透明又は半透明の材料で形成されているため、保護材料の充填状況を視認しながら注入でき、最適量の注入が可能となる。更に、充填箇所及びその近くの上側連結シートと保護板との隙間から保護材料の充填圧力を逃がすことができるので、連結部分のはらみ出し現象を防止できて材量費を低減でき、また、充填用空所内の空気も前記隙間から外部に逃がすことができて保護材料層への気泡の混入を防止できる。その結果、連結部分の品質の向上により遮水性能等を向上させることができ、しかも、施工能率を向上させることができる。 The protective material filled in the filling space is not exposed to the atmosphere, and foreign substances such as dust and dust in the atmosphere can be prevented from entering the protective material. In addition, by filling the filling space with the protective material while moving the injection port of the injector, it is possible to prevent the protective material from being increased in pressure feed distance and the pressure loss of the protective material from increasing. The filling equipment can also be reduced in size. Further, the upper connecting sheet and the protective plate are sequentially joined along the length direction of the filling space, and the curable protective material is sequentially injected into the filling space at the already joined portion. The integrity of the protective material layer and the upper connecting sheet can be enhanced. At this time, since the upper connecting sheet is formed of a transparent or translucent material, it can be injected while visually checking the filling state of the protective material, and an optimal amount can be injected. Furthermore, since the filling pressure of the protective material can be released from the gap between the filling location and the upper connecting sheet and the protective plate near the filling location, the protruding portion phenomenon can be prevented and the material cost can be reduced. The air in the use space can also escape to the outside through the gap, so that bubbles can be prevented from entering the protective material layer. As a result, the water shielding performance and the like can be improved by improving the quality of the connected portion, and the construction efficiency can be improved.
また、前記保護材料の注入機と該注入機に伴走する熱溶着機とを、前記充填用空所の長さ方向に沿って移動させながら、前記上側連結シートと前記保護板とを接合し、前記充填用空所内に前記保護材料を注入すれば、連結シートの迅速な接合によって保護材料を連結シートとの一体性を更に高め、連結部分の品質を更に向上させることができる。 In addition, the upper connecting sheet and the protective plate are joined while moving the injector of the protective material and the heat welding machine accompanying the injector along the length direction of the filling space, If the protective material is injected into the filling space, the integrity of the protective material and the connection sheet can be further increased by the rapid joining of the connection sheet, and the quality of the connection portion can be further improved.
以下、本発明に係る保護板の連結方法の実施形態について図面を参照しつつ説明する。 DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a method for connecting protective plates according to the present invention will be described with reference to the drawings.
図２のように保護板Ａは、保護材料層１の上下両面に外皮シート２，３をそれぞれ水密的に接着したサンドイッチ構造になっており、下側外皮シート３の左右両側部は保護材料層１の端面よりも外側に突出した耳状側部３１となっている。

The
次に、以上のように構成される保護板Ａ同士の連結方法について述べる。かかる連結方法では、上側及び下側の連結シートＢ１，Ｂ２及び硬化型の保護材料Ｃが用いられる。連結シートＢ１，Ｂ２は、外皮シート２，３と同様に、遮水性、可撓性及び熱溶着性を有する軟質の塩化ビニル等で形成され、また、上側連結シートＢ１は、充填状況の視認が可能なように透明又は半透明の材料で形成されている。保護材料Ｃは、液状原料の形態で連結部分に注入され、液状原料としては熱可塑性樹脂等のように遮水用材料そのものが液化しているものや、２液常温硬化型ポリウレタンのような材料が使用され、その配合により充填材の硬化時間を設定でき、硬化前はその良好な充填性により空隙のない保護材料層が形成される。なお、硬化後に可撓性及び所定の機械的強度を有するものであれば、これに限定されない。また、保護材料Ｃとして、水膨潤性材料を用いる場合は、例えば水膨潤性材料と水を予め混合し、これと液状原料等と混合し、得られた混合物を注入すれば良い。
（１）保護板Ａの配置
保護板Ａ同士は連結されて施設に敷設されるものであり、連結の際には、図２のように保護板Ａを列設し、隣接する保護板Ａの間に隙間を設け、隣接する保護板Ａの下側外皮シートの耳状側部３１を接触させる。
（２）下側外皮シート３同士の連結
次に、図３のように隣接する保護板Ａの下側外皮シート３の耳状側部３１を跨いだ状態で該耳状側部３１の上に下側連結シートＢ２を重ね、耳状側部３１と下側連結シートＢ１，Ｂ２の両側部とを溶着接合して下側外皮シート３同士の連結すると共に充填用空所４を形成する。溶着接合は、熱溶着機１００を耳状側部３１の長さ方向の一端部から他端部に向けて走らせることにより行われる。
Next, a method for connecting the protective plates A configured as described above will be described. In this connection method, upper and lower connection sheets B1 and B2 and a curable protective material C are used. The connecting sheets B1 and B2 are formed of soft vinyl chloride having water shielding properties, flexibility, and heat-welding properties, similar to the

次に、上側連結シートＢ１の他側端部と他方の保護板Ａの上側外皮シート２とを溶着接合し、充填用空所４内に保護材料Ｃを注入する。この場合、充填スピードと溶着スピードとの違いや、保護材料Ｃの注入圧による上側連結シートＢ１の浮き上がりを防止するなどの観点から、溶着接合を先行させた後に、接合が完了した箇所の充填用空所４内に保護材料Ｃを充填する。
Next, the other end portion of the upper connecting sheet B1 and the
そのために、図１のように注入機１０１の注入ホース１０１ａの先端の注出口１０１ｂを熱溶着機１００よりも後方に位置させ、保護材料Ｃの注入機１０１と該注入機１０１に伴走する熱溶着機１００を、注入ホース１０１ａと共に充填用空所４の長さ方向の一端部から他端部に向けて該充填用空所４に沿って移動させる。また、注入機１０１の注入ホース１０１ａを、未接合箇所の上側連結シートＢ１の他側端部と他方の保護板Ａの上側外皮シート２との間から充填用空所４内に挿入する（図１、図５参照）。
Therefore, as shown in FIG. 1, the
そして、上側連結シートＢ１の他側端部と他方の保護板Ａの上側外皮シート２とを充填用空所４の長さ方向に沿って順次溶着接合し、溶着接合が完了した箇所の充填用空所４内には注入ホース１０１ａの注出口１０１ｂから硬化型の保護材料Ｃを順次注入していく。注入時には、上側連結シートＢ１を通して、保護材料Ｃの充填状況を視認しながら、注入できる。

なお、保護板Ａの連結部分の両端部には、例えば図１のように保護材料Ｃの硬化前に保護材と同品質の物であらかじめ形成された詰め物Ｄを詰め込む等して端部処理を行う。 For example, as shown in FIG. 1, the end portions of the connecting portions of the protective plate A are processed by, for example, stuffing padding D formed in advance with the same quality as the protective material before the protective material C is cured. Do.
保護板Ａの保護材料層１や連結部に用いられる保護材料は、前記のものには限定されず、例えば樹脂類、ゴム類、ベントナイト、粘性土、混合土、高分子ゲル、セメント、無機ゲル等の公知の材料を使用することができる。すなわち、公知の有機材料、無機材料及びこれらの混合物のいずれも使用することができる。
The protective material used for the
このような材料としては、上記の透水係数及び変形率を充足するものであれば特に限定されない。有機材料として、例えばポリエステル、ポリプロピレン、ポリエチレン、ポリウレタン、エポキシ等の樹脂類、天然ゴム、イソプレン、ブチルゴム、ネオプレン（登録商標）等のゴム類等を挙げることができる。また、無機材料として、例えばセメント・コンクリート、石膏、粘土類、珪酸及びその塩類等が挙げられる。これらは１種又は２種以上で用いることができる。特に、本発明では、樹脂類を使用することが好ましく、その中でもポリウレタンが好ましい。 Such a material is not particularly limited as long as it satisfies the above water permeability coefficient and deformation rate. Examples of the organic material include resins such as polyester, polypropylene, polyethylene, polyurethane, and epoxy, and rubbers such as natural rubber, isoprene, butyl rubber, and neoprene (registered trademark). Examples of the inorganic material include cement / concrete, gypsum, clays, silicic acid and salts thereof. These can be used alone or in combination of two or more. In particular, in the present invention, it is preferable to use resins, and among them, polyurethane is preferable.
このように、保護板Ａの溶着作業と保護材料の充填作業を平行して行うことにより、連絡部において煤塵、粉塵、気泡などの異物が混入する可能性を低減できる。 Thus, by performing the welding operation of the protective plate A and the filling operation of the protective material in parallel, it is possible to reduce the possibility that foreign matters such as dust, dust and bubbles are mixed in the connecting portion.
また、本方法によって連結された連結部は保護板Ａと一体化され、その強度は一保護板Ａ自体の強度の８０％以上になることが確認された。 Moreover, it was confirmed that the connection part connected by this method is integrated with the protective plate A, and the strength thereof is 80% or more of the strength of the single protective plate A itself.
なお、保護板Ａは、地下壁や路面下等の防振材としても用いられるが、このような用途であっても連結部分は弱点にはならない。 In addition, although the protection board A is used also as an anti-vibration material, such as an underground wall and a road surface, even if it is such a use, a connection part does not become a weak point.
上記の実施形態においては、上側連結シートの一側端部を一方の保護板と先に接合しておいてから、上側連結シートの他方端部を他方の保護板と順次接合させつつ未接合箇所から注入機の注入口を充填用空所内に挿入して既接合箇所の充填用空所内に硬化型の保護材料を順次注入していく工法について説明したが、上側連結シートの両端部を隣り合う保護板に同時に接合させつつ、未接合箇所から注入機の注入口を充填用空所内に挿入して既接合箇所の充填用空所内に硬化型の保護材料を順次注入していくこともできる。 In the above embodiment, one end of the upper connecting sheet is bonded to one protective plate in advance, and then the other end of the upper connecting sheet is sequentially bonded to the other protective plate while not being joined. We explained the method of inserting the injection port of the injection machine into the filling cavity and sequentially injecting the curing type protective material into the filling cavity at the already joined part, but the both ends of the upper connecting sheet are adjacent to each other While simultaneously bonding to the protective plate, it is also possible to insert the injection port of the injection machine into the filling space from the unbonded portion and sequentially inject the curable protective material into the filling space at the already bonded portion.
