Description

本発明は、除染廃棄物の仮置き場に敷かれた遮水シートを自走しながら切断する自走式カッター装置に関する。 The present invention relates to a self-propelled cutter device that cuts a water-impervious sheet laid in a temporary storage place for decontamination waste while self-propelling.

原発事故によって東日本の広範囲が放射性物質によって汚染され、除染により発生した除染土壌等の除染廃棄物が除染廃棄物専用フレコンバッグに充填され、除染廃棄物専用フレコンバッグを一時的に保管するために空き地や耕作地等が仮置き場として使用されている。仮置き場では放射性物質が漏れるのを防止するために遮水シートが敷かれ、その上にフレコンバッグが仮置きされている。 A wide area of eastern Japan was contaminated with radioactive substances due to the nuclear accident, and decontamination waste such as decontaminated soil generated by decontamination was filled in the decontamination waste dedicated flexible container bag, and the decontamination waste dedicated flexible container bag was temporarily used. Unoccupied land and cultivated land are used as temporary storage for storage. In the temporary storage area, a water-impervious sheet is laid to prevent radioactive substances from leaking, and a flexible container bag is temporarily placed on it.

フレコンバッグを仮置き場から中間貯蔵施設へ移送した後は、仮置き場に敷かれていた遮水シートを処分するため、この遮水シートを人力によりカッターで切断して、処分している。遮水シートの切断作業では、作業者に対し労力的に大きな負担となるだけでなく作業時間がかかるために効率的ではないので、コンクリートカッターのように回転刃を備えたカッター装置〈特許文献1参照〉により切断して処分することが考えられる。 After the flexible container bag is transferred from the temporary storage facility to the interim storage facility, the water-impervious sheet laid in the temporary storage facility is manually cut with a cutter and disposed of. The cutting work of a geomembrane sheet is not efficient because it not only puts a heavy burden on the operator but also takes a long time, so a cutter device equipped with a rotary blade like a concrete cutter <Patent Document 1 It is conceivable to cut and dispose of by referring to>.

特開201470427号公報Japanese Unexamined Patent Publication No. 201470427

しかしながら、コンクリートカッターではカッターを冷却するために冷却水を使用するが、汚染物質の流出を防止しなければならないことから水の使用ができないのでコンクリートカッターは使用できない。現状では、人力に代わる効率的な遮水シートの切断手段が見当たらないことから、遮水シートの切断作業は人力に頼らざるを得ない。 However, although the concrete cutter uses cooling water to cool the cutter, the concrete cutter cannot be used because water cannot be used because the outflow of pollutants must be prevented. At present, there is no efficient means for cutting a geomembrane sheet in place of human power, so the work of cutting a geomembrane sheet has to rely on human power.

そこで、本発明は、除染廃棄物の仮置き場に敷かれた遮水シートを安全に切断することが可能な自走式カッター装置を提供するものである。 Therefore, the present invention provides a self-propelled cutter device capable of safely cutting a water-impervious sheet laid in a temporary storage place for decontamination waste.

本願の請求項1の発明は、除染廃棄物の仮置き場に敷かれた遮水シートを自走しながら切断する自走式カッター装置が、クローラで自走する車体と遮水シートを切断するカッター装置からなり、前記カッター装置が前記車体の前部に装着されてワイヤにより上下方向に回動可能に支持されるとともに、駆動装置で前記遮水シートの切断方向に回転する回転刃と前記回転刃の下側に前記遮水シートを持ち上げて支持する遮水シート支持板を備え、前記遮水シート支持板は、中央に前記回転刃が入り込む長孔が形成され、前記ワイヤは、一端が前記車体に立設されたシリンダーのピストンロッドに固定され、他端が前記カッター装置に固定されるとともに、前記回転刃と前記遮水シート支持板が前記遮水シートの下の地面に接しない高さに前記カッター装置を引き上げて回動させるワイヤであることを特徴とする自走式カッター装置である。 According to the invention of claim 1 of the present application, a self-propelled cutter device that cuts a water-impervious sheet laid in a temporary storage place for decontamination waste while self-propelling cuts a self-propelled vehicle body and a water-impervious sheet by a crawler. It is composed of a cutter device, the cutter device is mounted on the front part of the vehicle body and is rotatably supported in the vertical direction by a wire, and a rotary blade and the rotation that rotate in the cutting direction of the water-impervious sheet by the drive device. A water-impervious sheet support plate for lifting and supporting the water-impervious sheet is provided on the lower side of the blade, the water-impervious sheet support plate is formed with an elongated hole in the center into which the rotary blade enters, and one end of the wire is said. It is fixed to the piston rod of a cylinder erected on the vehicle body, the other end is fixed to the cutter device, and the height at which the rotary blade and the impermeable sheet support plate do not contact the ground under the impermeable sheet. It is a self-propelled cutter device characterized by being a wire that pulls up and rotates the cutter device.

本発明の自走式カッター装置は、人力によることなく自走して回転刃により遮水シートを切断していくので、人力によるカッターの切断作業に比べて効率的となり、作業時間が大幅に短縮されるとともに、作業者の労力を大幅に軽減された。 Since the self-propelled cutter device of the present invention runs on its own without human power and cuts the water-impervious sheet with a rotary blade, it is more efficient than the manual cutting work of the cutter, and the work time is significantly shortened. At the same time, the labor of workers was greatly reduced.

また、切断作業の際に汚染物質の流出を防止しなければならないことから水の使用ができないが、本発明の自走式カッター装置は、回転刃の回転による飛散することがないため、コンクリートカッターのような散水の必要もない。 In addition, water cannot be used because it is necessary to prevent the outflow of pollutants during cutting work, but the self-propelled cutter device of the present invention does not scatter due to the rotation of the rotary blade, so that it is a concrete cutter. There is no need to sprinkle water like this.

本発明の自走式カッター装置は、回転刃と遮水シート支持板が遮水シートの下の地面に接しない高さにカッター装置を引き上げられるため、回転刃が遮水シートの下の土に接触しないので、土の石等に接触して火花が飛ぶことがないので、火災のおそれもない。 In the self-propelled cutter device of the present invention, since the cutter device can be pulled up to a height at which the rotary blade and the impermeable sheet support plate do not contact the ground under the impermeable sheet, the rotary blade is placed on the soil under the impermeable sheet. Since it does not come into contact with it, it does not come into contact with earth stones and sparks, so there is no risk of fire.

本発明の自走式カッター装置は、仮置き場が設けられている場所が差水シートの下の地面が軟弱で車輪がめり込んで走行できない場所においても、クローラで走行できるので切断作業が可能となる。 The self-propelled cutter device of the present invention can run on a crawler even in a place where a temporary storage place is provided because the ground under the water difference sheet is soft and the wheels are sunk and cannot run, so that cutting work is possible. ..

本発明の実施例について図面を参照しながら説明する。 Examples of the present invention will be described with reference to the drawings.

図1〜4において、本発明の自走式カッター装置は、クローラ3で自走して走行する車体1と遮水シートを切断するカッター装置2で構成される。車体1のクローラ3はゴム製のキャタピラなので、車輪がのめり込むような軟弱な地面であってものめり込むことなく走行することが可能である。車体1の上には操作員の座る運転席が設けられている。 In FIGS. 1 to 4, the self-propelled cutter device of the present invention includes a vehicle body 1 that runs by itself on a crawler 3 and a cutter device 2 that cuts a water-impervious sheet. Since the crawler 3 of the vehicle body 1 is a rubber caterpillar, it is possible to travel without being sunk even on a soft ground where the wheels are sunk. A driver's seat on which the operator sits is provided on the vehicle body 1.

カッター装置2は車体1の前部に上下方向に回動可能に装着され、ワイヤ4により所定のレベルに支持されている。ワイヤ4は、一端が車体1上に立設されたシリンダーのピストンロッド5の先端に固定され、他端がカッター装置2の側部6に固定されて、カッター装置2が支持されている。 The cutter device 2 is rotatably mounted on the front portion of the vehicle body 1 in the vertical direction, and is supported by a wire 4 at a predetermined level. One end of the wire 4 is fixed to the tip of the piston rod 5 of the cylinder erected on the vehicle body 1, and the other end is fixed to the side portion 6 of the cutter device 2 to support the cutter device 2.

カッター装置2は、駆動装置7で遮水シートSの切断方向に回転する回転刃8を備え、回転刃8は危険防止のためにカバーで覆われている。回転刃8の下側には遮水シートSを下から持ち上げて支持する遮水シート支持板9が配置されている。遮水シート支持板9の先端は、回転刃8より前方に延びており、遮水シートSを、回転刃8で切断する前に持ち上げて支持するようになっている。 The cutter device 2 includes a rotary blade 8 that rotates in the cutting direction of the water-impervious sheet S by the drive device 7, and the rotary blade 8 is covered with a cover to prevent danger. On the lower side of the rotary blade 8, a water-impervious sheet support plate 9 for lifting and supporting the water-impervious sheet S from below is arranged. The tip of the water-impervious sheet support plate 9 extends forward from the rotary blade 8 so that the water-impervious sheet S is lifted and supported before being cut by the rotary blade 8.

遮水シート支持板9の中央部には、回転刃8が入る長孔10が形成されている。長孔10に回転刃8が入ることにより、回転刃8は遮水シート支持板9に支持された遮水シートSの下側に抜けて遮水シートを確実に切断することができる。 An elongated hole 10 into which the rotary blade 8 is inserted is formed in the central portion of the water-impervious sheet support plate 9. When the rotary blade 8 is inserted into the elongated hole 10, the rotary blade 8 can be pulled out to the lower side of the water-impervious sheet S supported by the water-impervious sheet support plate 9 to reliably cut the water-impervious sheet.

次に、本発明の自走式カッター装置による切断作業について説明する。 Next, the cutting operation by the self-propelled cutter device of the present invention will be described.

自走式カッター装置を遮水シート支持板9の先端が遮水シートSの端の手前の位置で停車させた後、作業員が遮水シートSの端を遮水シート支持板9が入り込む空間ができる高さまで持ち上げ、自走式カッター装置を前進させて遮水シート支持板9を遮水シートSの端に形成されている空間内に入れて停止させる。 After stopping the self-propelled cutter device at a position where the tip of the water-impervious sheet support plate 9 is in front of the end of the water-impervious sheet S, a space where a worker enters the end of the water-impervious sheet S. The self-propelled cutter device is advanced so that the water-impervious sheet support plate 9 is put into the space formed at the end of the water-impervious sheet S and stopped.

次いで、シリンダーのピストンロッド5を上昇させることによりワイヤ4を引いてカッター装置2を上方向に回動させて、回転刃8と遮水シート支持板9が遮水シートSの下の地面に接しない高さにセットする。 Next, by raising the piston rod 5 of the cylinder, the wire 4 is pulled to rotate the cutter device 2 upward, and the rotary blade 8 and the impermeable sheet support plate 9 come into contact with the ground under the impermeable sheet S. Set to a height that does not.

セットが終了すると、回転刃8を回転させ、自走式カッター装置を自走させて前進させると、遮水シート支持板9が遮水シートSを持ち上げて支持するとともに、遮水シートは回転刃8により切断されていく。 When the setting is completed, the rotary blade 8 is rotated, and the self-propelled cutter device is self-propelled to advance. It is cut by 8.

こうして、回転刃8が地面に接することなくかつ冷却水を使用することなく、遮水シートSを縦方向に切断していく。こうして間隔をおいて帯状に切断し、さらに必要に応じて、横方向に切断した後、切断した遮水シートSを剥がし、処分していく。 In this way, the water-impervious sheet S is cut in the vertical direction without the rotary blade 8 coming into contact with the ground and without using cooling water. In this way, it is cut into strips at intervals, and if necessary, it is cut in the lateral direction, and then the cut water-impervious sheet S is peeled off and disposed of.
