Description

本発明はU型コンクリートブロックを配列して構成するU字溝水路において、継目から水漏れがしないようにする水漏れ防止構造、及び粘着防水シート材に関するものである。   The present invention relates to a water leakage prevention structure that prevents leakage of water from a seam, and an adhesive waterproof sheet material in a U-shaped groove channel configured by arranging U-shaped concrete blocks.

近年、水田へ水を供給する水路としてU型コンクリートブロックが多用されている。図9は一般的なU型コンクリートブックの外観を示す具体例であり、底部(イ)の両側には側部(ロ)、(ロ)が起立し、その断面はU型を形成している。このU型コンクリートブロックを長手方向に配列することで、U字溝水路を構成することが出来る。   In recent years, U-shaped concrete blocks are frequently used as water channels for supplying water to paddy fields. FIG. 9 is a specific example showing the appearance of a general U-shaped concrete book. Sides (B) and (B) stand up on both sides of the bottom (A), and the cross section forms a U-shape. . By arranging the U-shaped concrete blocks in the longitudinal direction, a U-shaped groove water channel can be configured.

型枠を作ってコンクリートを流し込むことでU字溝水路を構成することは可能であるが、規格化されたU型コンクリートブロックは工場で量産することが出来、現場へ搬送して所定の場所に配列するだけの作業でU字溝水路を簡単に造成することが出来ることから、近年ではこのU型コンクリートブロックを用いた水路が殆どである。   Although it is possible to construct a U-shaped groove channel by making a formwork and pouring concrete into it, standardized U-shaped concrete blocks can be mass-produced at the factory, transported to the site and put into place In recent years, most of the water channels using this U-shaped concrete block can be created by simply arranging them.

ところで、U字溝水路は複数のU型コンクリートブロックが配列され、継目にはモルタルが詰められて水漏れしないようにしている。しかし、長い年月が経過すると、継目のモルタルにはヒビが入って該継目から水漏れを生じるケースが多発する。特に、道路を大型車両が走行する際に発生する振動にてモルタルが剥れ、また地震が発生すると継目に亀裂が生じる。   By the way, a plurality of U-shaped concrete blocks are arranged in the U-shaped groove water channel, and the seam is filled with mortar to prevent water leakage. However, when a long time has passed, there are many cases where the mortar of the seam cracks and leaks from the seam. In particular, the mortar peels off due to vibration generated when a large vehicle travels on the road, and when an earthquake occurs, the seam cracks.

稲作では田植え時期から穂が出るまでの期間は水を必要とし、その為に水田には水が満ちているのが常であるが、穂が実って収穫の稲刈り時期が近づくと水田に水を入れることはなく、むしろ水田を乾燥する必要がある。このような時期にU字溝水路の継目から漏れる水が水田に流れ込むと、水田を乾燥することが出来ず、その結果、稲穂が十分に実ることが出来なくなる。   In rice farming, water is needed from the time of planting to the time when the ears appear, so the paddy fields are usually filled with water, but when the ears grow and the harvesting time for harvesting approaches, the paddy fields are filled with water. It is not necessary to put in, but rather it is necessary to dry the paddy field. If water leaking from the seam of the U-shaped ditch channel flows into the paddy field at such a time, the paddy field cannot be dried, and as a result, the ear of rice cannot be fully produced.

その結果、米の収穫量は減少すると共に品質も低下する。一方、収穫時にはコンバインが水田へ入って稲刈りを行なうことになるが、U字溝水路から漏れる水が水田に流れ込むならば、水田は乾燥しなくて軟らかく、非常に重いコンバインがスムーズに走行することが出来なくなる。勿論、田植え後で水が必要な時期であっても、必要以上の水は好ましくない。   As a result, rice yield is reduced and quality is also reduced. On the other hand, when harvesting, the combine enters the paddy field and harvests the rice, but if the water leaking from the U-shaped ditch channel flows into the paddy field, the paddy field is not dry and soft, and the very heavy combine runs smoothly. Cannot be done. Of course, more water than necessary is not preferable even when water is needed after planting.

特開平7−127119号に係る「排水路の構造」は、連続して設けられる排水路同士の継目を簡単な構成で止水でき、敷設作業を容易かつ効率的に行えるようにしている。
すなわち、U字溝本体の一方の側部端面に沿って連続した係止溝が形成され、対応する帯状に形成された水膨張性止水材が装着される。係止溝内部には係止突起が幅方向に突出形成され、水膨張性止水材の脱落を防止する。敷設時には、水膨張性止水材が設けられた一方の側部端面を他のU字溝本体の他方の側部端面に向けて設置し、水分を供給するのみでこれら側部端面間の隙間で水膨張性止水材が水膨張して止水を確実に行える。
According to Japanese Patent Laid-Open No. 7-127119, “Drainage channel structure” allows water to be stopped with a simple structure at a joint between drainage channels provided continuously, so that laying work can be performed easily and efficiently.
That is, a continuous locking groove is formed along one side end face of the U-shaped groove main body, and a water-swellable water-stopping material formed in a corresponding band shape is attached. A locking projection is formed in the locking groove so as to protrude in the width direction, thereby preventing the water-swellable water-stopping material from falling off. At the time of laying, install one side end face provided with a water-expandable water stop material toward the other side end face of the other U-shaped groove body, and just supply moisture to the gap between these side end faces Thus, the water-swellable water-stopping material can swell and reliably stop water.

上記排水路の構造はU字溝水路を造成する時には有効ではあるが、時期が経過して水膨張性止水材が退化すれば水漏れを生じる。しかも、水膨張性止水材はU字溝本体の側部端面に取付けられる為に、新たな水膨張性止水材と交換する場合には、U字溝本体を一旦撤去しなくてはならず、U字溝水路を新に構築する以上の工事と成ってしまう。   The structure of the drainage channel is effective when a U-shaped groove channel is constructed, but water leaks if the water-expandable water-stopping material degenerates with the passage of time. Moreover, since the water-expandable water-stopping material is attached to the side end face of the U-shaped groove body, when replacing with a new water-expandable water-stopping material, the U-shaped groove body must be removed once. Therefore, it would be more work than constructing a new U-shaped ditch channel.

出願人は平成23年10月25日付けで「U字溝水路の継目水漏れ防止構造」に関して特許出願を行っている(特開2013−91944)。すなわち、このU字溝水路の継目水漏れ防止構造は、継目を塞ぐように底面、両内側面、及び上端面に沿ってシールを貼着している。そして該シールは3層構造とし、表面はサンド付き改質アスファルト層、中間層はガラス繊維織布層、下層は加熱することで粘着性を有す粘着アスファルト層を積層して構成している。   The applicant has filed a patent application on “Own groove water channel prevention structure” on October 25, 2011 (Japanese Patent Laid-Open No. 2013-91944). That is, in the seam water leakage prevention structure of the U-shaped groove water channel, the seal is attached along the bottom surface, both inner surfaces, and the upper end surface so as to close the seam. The seal has a three-layer structure, in which the surface is a modified asphalt layer with sand, the intermediate layer is a glass fiber woven fabric layer, and the lower layer is laminated with an adhesive asphalt layer having adhesiveness by heating.

しかし、上記U字溝水路の継目水漏れ防止構造では、U字溝内周面にシールを貼着する際に該シールを加熱しなくてはならず、その作業は面倒である。

However, in the seam leakage prevention structure of the U-shaped groove water channel, the seal must be heated when the seal is attached to the inner peripheral surface of the U-shaped groove, and the work is troublesome.
"Structure of drainage channel" according to Japanese Patent Laid-Open No. 7-127119 “Seam water leakage prevention structure of U-shaped groove water channel” according to JP2013-91944A

このように、U型コンクリートブロックを配列して構成されるU字溝水路には上記のごとき問題がある。本発明が解決しようとする課題はこの問題点であり、U型コンクリートブロックの継目から水漏れを生じないようにシールしたU字溝水路の継目水漏れ防止構造、及び防水シールを提供する。ここで、防水シールはU字溝水路の継目水漏れ防止構造を対象とするのみならず、他の部材継目からの水漏れ防止にも適用する。   As described above, the U-shaped groove water channel constituted by arranging U-shaped concrete blocks has the above-described problems. The problem to be solved by the present invention is this problem, and provides a seam leakage prevention structure of a U-shaped groove water channel sealed so as not to cause water leakage from a seam of a U-shaped concrete block, and a waterproof seal. Here, the waterproof seal is applied not only to the joint water leakage preventing structure of the U-shaped groove water channel but also to preventing water leakage from other member seams.

本発明に係るU字溝水路は、U型コンクリートブロックを配列して構成し、そしてU型コンクリートブロックの継目にはシール材を貼着している。勿論、従来通り継目にはモルタルが詰められているが、シール材はU字溝水路の継目部内面に貼着される。そして、該シール材は新に設置されるU字溝水路に限らず、既存のU字溝水路の継目をシールする為に使用出来る。   The U-shaped groove channel according to the present invention is configured by arranging U-shaped concrete blocks, and a sealing material is attached to the joints of the U-shaped concrete blocks. Of course, the seam is filled with mortar as usual, but the sealing material is attached to the inner surface of the seam part of the U-shaped groove water channel. And this sealing material can be used in order to seal the joint of the existing U-shaped water channel not only in the newly installed U-shaped water channel.

ここで、本発明に係るシール材は遮水層に粘着層を設けたものであり、該粘着層を介してU字溝水路などの継目に貼着することが出来る。ここで、上記遮水層としての具体的な構造は限定しないことにする。
例えば、上記遮水層を4層構造として構成し、上面側からエンビコーティング層、ポリエステル繊維層、エンビコーティング層、そして粘着層とすることが出来る。このシール材は4層を積層した構造であり、一定幅の帯状を成してロール巻きされている。その為に最下層の粘着層には離型紙を貼り合せてロール巻きされ、必要に応じて適当な長さに切断して使うことが出来るようにしている。
Here, the sealing material which concerns on this invention provides the adhesion layer in the water-impervious layer, and can stick it to seams, such as a U-shaped groove water channel, via this adhesion layer. Here, the specific structure as the water shielding layer is not limited.
For example, the water-shielding layer can be configured as a four-layer structure, and can be an envico-coating layer, a polyester fiber layer, an envico-coating layer, and an adhesive layer from the upper surface side. This sealing material has a structure in which four layers are laminated, and is rolled in a band shape having a constant width. For this purpose, the lowermost adhesive layer is rolled by laminating release paper so that it can be cut into an appropriate length if necessary.

該シール材を用いて継手部をシールする場合、U字溝には水が流れないように止水し、シール材を貼着する継手部に付着しているコケや土埃を除去し、雑巾などを用いて水拭きする。そして、シーリング材を継手に生じた穴や凹部に充填し、ヘラなどを用いて充填したシーリング材を薄く押し広げる。   When sealing the joint using this sealing material, stop the water so that water does not flow in the U-shaped groove, remove moss and dust adhering to the joint to which the sealing material is adhered, dust, etc. Wipe with water. Then, the sealing material is filled in the hole or recess formed in the joint, and the filled sealing material is thinly spread using a spatula or the like.

また、シール材を貼着する領域にプライマーを均一に塗布し、適当な長さに切断したシール材を所定の領域に貼着する。そして、貼着したシール材の両側端にシーリング材を塗布する。ここで、本発明のシール材を貼着して水漏れを防止する対象部材はU字溝に限らず、他のコンクリート部材の継目にも貼着して該継目部からの水漏れを防止するように機能する。   In addition, a primer is uniformly applied to a region where the sealing material is adhered, and the sealing material cut into an appropriate length is adhered to a predetermined region. And a sealing material is apply | coated to the both ends of the sticking sealing material. Here, the target member for preventing water leakage by adhering the sealing material of the present invention is not limited to the U-shaped groove, and is also applied to the seam of other concrete members to prevent water leakage from the seam portion. To function.

本発明に係るシール材は遮水層に粘着層を積層してロール巻きされたもので、必要な長さに切断して使うことが出来る。例えば、上記シール材を4層構造として上面側からエンビコーティング層、ポリエステル繊維層、エンビコーティング層、そして粘着層として構成する場合、上記エンビコーティング層は耐水性を持っている為にシール内部への水の浸透を防止し、また耐候性に優れていることで基材となるポリエステル繊維層の紫外線劣化を防止する。シールの基材となるポリエステル繊維層は強度が高くて耐久性に優れている。
シール材を貼着する継目部の内周面を綺麗に掃除し、貼着する領域にプライマーを塗布して適当な長さに切断したシール材を貼着することが出来、その作業は簡単である。
The sealing material according to the present invention is a roll obtained by laminating an adhesive layer on a water-impervious layer and can be used after being cut to a required length. For example, when the sealing material is constituted as a four-layer structure from the upper surface side as an coating layer, a polyester fiber layer, a coating layer, and an adhesive layer, the coating layer has water resistance, so The penetration of water is prevented, and the polyester fiber layer as a base material is prevented from being deteriorated by ultraviolet rays because of its excellent weather resistance. The polyester fiber layer serving as a base material for the seal has high strength and excellent durability.
Clean the inner peripheral surface of the seam part where the sealing material is to be applied, apply a primer to the area to be applied, and apply the sealing material cut to an appropriate length. is there.

ところで、このシール材を使用してU型コンクリートブロックを配列したU字溝水路の継目部にシール材を貼着することで、継目からの水漏れを防止することが出来る。U字溝水路を造成して新しい時に水漏れは無いが、時期が経過することでU型コンクリートブロックは老朽化し、特に継目に詰めたモルタルが退化して水漏れを発生する。そこで、該シール材を貼り付けることで簡単にしかも大きな費用をかけることなく水漏れを防止出来る。   By the way, by using this sealing material and sticking the sealing material to the seam portion of the U-shaped groove water channel in which the U-shaped concrete blocks are arranged, water leakage from the seam can be prevented. There is no water leakage when the U-shaped channel is constructed and new, but with the passage of time, the U-shaped concrete block becomes obsolete, and in particular, the mortar packed in the joint is degenerated and water leakage occurs. Therefore, it is possible to prevent water leakage simply by attaching the sealing material without incurring a large cost.

水漏れが防止されることで、稲が実った収穫時には水田を乾燥させることが出来、その為に、収穫量が増えると共に米の品質は向上する。また、田植え後の水田に適量の水を満たすことが出来る。そして、稲刈り時に、コンバインは乾燥した水田に入り易く、スムーズに走行して効率よく稲刈り作業を行うことも可能となる。   By preventing water leakage, it is possible to dry the paddy field when the rice is harvested, which increases the yield and the quality of the rice. In addition, an appropriate amount of water can be filled in the rice field after planting. During harvesting, the combine can easily enter a dry paddy field and can smoothly run to efficiently harvest rice.

図1はU字溝水路の継目にシールを貼着したシール構造を示す本発明の実施例である。同図の1はU型コンクリートブロック、2はシール材、3は継目をそれぞれ表わしている。U字溝水路はU型コンクリートブロック1,1・・・を長手方向に配列して構成し、継目3,3・・・にはモルタルが詰められることで、U型コンクリートブロック1,1・・・が段差なく接続され、また継目3,3・・・からの水漏れを防止している。従って、U字溝水路には水が流れて必要な時に水田へ供給することが出来る。   FIG. 1 is an embodiment of the present invention showing a seal structure in which a seal is attached to a seam of a U-shaped groove water channel. In the figure, 1 represents a U-shaped concrete block, 2 represents a sealing material, and 3 represents a joint. The U-shaped groove channel is composed of U-shaped concrete blocks 1, 1... Arranged in the longitudinal direction, and the joints 3, 3. -Is connected without any step and prevents water leakage from the joints 3, 3,. Accordingly, water flows through the U-shaped groove channel and can be supplied to the paddy field when necessary.

このU字溝水路は水田へ水を供給する為のもので、水田より僅かに高い位置に設置され、該U字溝水路の所々には流入口が設けられ、この流入口を開くことで水田へ水が流れるように成っている。勿論、排水用の水路もあるが、排水用水路は水田より低い位置に設けられ、その為に該水田に流れ込む水漏れが問題視されることはない。   This U-shaped ditch channel is for supplying water to the paddy field. It is installed at a position slightly higher than the paddy field, and inflow places are provided in places of the U-shaped ditch channel. The water is flowing. Of course, there is also a drainage channel, but the drainage channel is provided at a position lower than the paddy field, and therefore, there is no problem of water leakage flowing into the paddy field.

ところで、時の経過と共にU字溝水路を構成する上記U型コンクリートブロック1の内面は水の流れで浸食され、特に継目3に詰めたモルタルには亀裂が入り隙間穴が発生する。この隙間穴を埋める為に再度モルタルを詰めることも可能であるが、本発明では継目3を被覆するようにシール材2を貼着して隙間穴を塞ぐことが出来る。すなわち、シール材2の貼着にて水漏れが防止される。   By the way, with the passage of time, the inner surface of the U-shaped concrete block 1 constituting the U-shaped groove channel is eroded by the flow of water, and in particular, cracks occur in the mortar packed in the joint 3 to generate gap holes. In order to fill this gap hole, it is possible to refill the mortar, but in the present invention, the sealing material 2 can be stuck so as to cover the joint 3 to close the gap hole. That is, water leakage is prevented by sticking the sealing material 2.

図2は継目3に貼り付けるシール材2を示す具体例である。本発明に係るシール材2の基本構造は遮水層に粘着層を積層したもので一定幅の帯状をなしている。ここで、上記遮水層の具体例として、上面側からエンビコーティング層4、ポリエステル繊維層5、エンビコーティング層4として、これに粘着層と成るブチルゴム6が積層した構造としている。   FIG. 2 is a specific example showing the sealing material 2 attached to the joint 3. The basic structure of the sealing material 2 according to the present invention is a belt-like structure having a certain width, in which an adhesive layer is laminated on a water shielding layer. Here, as a specific example of the water shielding layer, an enviromental coating layer 4, a polyester fiber layer 5, and an enviromentation coating layer 4 are laminated from the upper surface side, and butyl rubber 6 serving as an adhesive layer is laminated thereon.

ところで、上記エンビコーティング層4は耐水性を持っている為にシール内部への水の浸透を防止し、また耐候性に優れている。そこで、基材となるポリエステル繊維層5の紫外線劣化を防止する。そして、シール材2の基材となるポリエステル繊維層5は強度が高くて耐久性に優れている。
本発明の防水シール材2はポリエステル繊維層4を上面側と下面側に積層したエンビコーティング層4,4にてサンドイッチ構造とすることで高い防水性を発揮し、継目3からの水漏れが防止される。
By the way, since the above-mentioned enviro coating layer 4 has water resistance, it prevents the penetration of water into the seal and is excellent in weather resistance. Therefore, UV degradation of the polyester fiber layer 5 serving as a base material is prevented. And the polyester fiber layer 5 used as the base material of the sealing material 2 has high strength, and is excellent in durability.
The waterproof sealing material 2 of the present invention exhibits a high waterproof property by sandwiching the polyester fiber layer 4 on the upper surface side and the lower surface side to provide a waterproof structure, and prevents water leakage from the seam 3. Is done.

そして、上記ブチルゴム6で構成される粘着層は粘着性と追従性に優れ、コンクリートブロック表面の凹凸部に入り込んで粘着され、シール材2をU字溝の継目部に強固に接着することが出来る。また、ブチルゴム6は防水性も兼ね備えており、上記エンビコーティング層4、ポリエステル繊維層5、エンビコーティング層4の積層構造と合わせて、継目からの高い漏水防止性能を発揮できる。   The pressure-sensitive adhesive layer composed of the butyl rubber 6 is excellent in pressure-sensitive adhesiveness and followability, and enters and adheres to the concavo-convex portion on the surface of the concrete block. . The butyl rubber 6 also has waterproofness, and can exhibit high water leakage prevention performance from the seam in combination with the laminated structure of the enviro coating layer 4, the polyester fiber layer 5, and the enviro coating layer 4.

図3はこのシート材2をU字溝水路の継目3に貼着した場合の断面図であり、U型コンクリートブロック1,1の内面は侵食して荒れた面と成っている為に、接着強度を向上する為にプライマーを塗布してプライマー層7を有している。また、継目3にはシーリング材8を充填する。シーリング材8としてモルタルでもよいが、弾性に優れて継目3の動きに対して追従するシリコン系のシーリング材8を使用し、コーキングガンを使用して継目3に発生した穴や凹部に充填することが出来る。   FIG. 3 is a cross-sectional view when this sheet material 2 is adhered to the seam 3 of the U-shaped groove water channel. Since the inner surfaces of the U-shaped concrete blocks 1 and 1 are eroded and rough, they are bonded. In order to improve the strength, a primer is applied to have a primer layer 7. The seam 3 is filled with a sealing material 8. Mortar may be used as the sealing material 8, but a silicon-based sealing material 8 that has excellent elasticity and follows the movement of the joint 3 is used, and a hole or a recess formed in the joint 3 is filled using a caulking gun. I can do it.

勿論、施工時にはモルタル9を継目3に詰めてU型コンクリートブロック1,1・・・を繋ぎ、継目3から水漏れが発生した時の補修用としてシリコン系のシーリング材8を用いることも可能である。すなわち、モルタルで構成した継目3の亀裂にシリコン系シーリング材8をコーキングガンにて充填する。   Of course, the mortar 9 is packed in the joint 3 at the time of construction, and the U-shaped concrete blocks 1, 1... Are connected, and the silicon-based sealing material 8 can be used for repairing when water leaks from the joint 3. is there. That is, the silicon sealing material 8 is filled with a caulking gun in the crack of the joint 3 made of mortar.

図4はU字溝水路の継目3にシール2を貼着した断面を示している。該シール2は底面10、内側面11,11、及び上端面12,12に沿って隙間なく貼着される。継目3に亀裂が生じる箇所は所々であり、水漏れを生じている箇所を確認したところでU字溝水路を流れる水を止めて該シール材2を貼着することが出来る。図4に示すように貼り付けるだけの作業であり、U型コンクリートブロック1を掘り起こす必要はなく、至って簡単で手軽に水漏れの補修することが出来る。   FIG. 4 shows a cross section in which the seal 2 is adhered to the joint 3 of the U-shaped groove water channel. The seal 2 is stuck along the bottom surface 10, the inner side surfaces 11, 11, and the upper end surfaces 12, 12 without any gaps. There are places where the seam 3 is cracked, and when the place where the water leaks is confirmed, the water flowing through the U-shaped groove water channel can be stopped and the sealing material 2 can be adhered. As shown in FIG. 4, the work is simply pasting, and it is not necessary to dig up the U-shaped concrete block 1, and it is extremely simple and easy to repair water leakage.

図5〜図8はU字溝水路の継目に防水シート材を貼着して継目からの水漏れを防ぐ作業工程を示す具体例である。
(1)は施工前の水路を示している。シール材2を貼着するには水路に水が流れていてはならず、その為に止水される。

FIG. 5 to FIG. 8 are specific examples showing a work process for sticking a waterproof sheet material to the seam of the U-shaped groove water channel to prevent water leakage from the seam.
(1) shows the water channel before construction. In order to stick the sealing material 2, water must not flow in the water channel, and therefore the water is stopped.
(2) Since the inner surface of the joint where the sheet material 2 is adhered is dirty and difficult to adhere, the attached moss and dirt are removed using a wire brush or the like. Then, water is wiped with a rag, and after cleaning, the inner surface of the joint portion of the water channel is completely dried.

(3)シーリング材を目地部に充填する。すなわち、モルタルが充填されていた目地部には水の流れで浸食されて穴が形成される場合があり、これら穴や凹部にシーリング材を詰めて平坦化する。
