【発明の属する技術分野】
本発明は、橋等の路面の増厚工事や空港滑走路の路面に付着したタイヤゴム等の除去作業に好適な舗装表面のはつり方法及び装置に関する。
【0002】
【従来の技術】
従来のこの種の舗装表面のはつり方法としては、例えば図7に示すように、互いに略等速進行する二台の車両a,bの内の一方の車両aに超高圧水ポンプユニットcを搭載すると共に、他方の車両bで回転式の複数の噴射ノズルdを備えた路面はつり機eを牽引し、超高圧水ポンプユニットcから路面はつり機eの噴射ノズルdに超高圧水を供給することにより、該噴射ノズルdの噴射口から舗装表面hに向けて超高圧水を噴射してその衝撃力により舗装表面hのはつりを行うようにしたものが知られている。
【0003】
そして、はつりにより生じた表層材と水との混合汚濁水をポータブル高圧水洗浄機gを用いて一カ所に集め、バキュームカーiによって吸引回収するようにしている。
【0004】
【発明が解決しようとする課題】
しかしながら、上記従来の舗装表面のはつり方法においては、噴射ノズルdから噴射された超高圧水がそのまま使い捨てにされるため水の浪費となり、しかも、はつりにより生じた表層材と水との混合汚濁水をポータブル高圧水洗浄機gを用いて一カ所に集め、バキュームカーiによって吸引回収するようにしているため、汚濁水の吸引回収作業に多大な手間がかかり、はつり作業全体の作業効率が著しく低下するという問題がある。
【0005】
また、はつりにより生じた表層材と水との混合汚濁水を一カ所に集める際にポータブル高圧水洗浄機gから噴射される水の量も大量となり、結果として大量の汚濁水を生み、バキュームカーiに吸引回収された汚濁水の処理コストが高くつくという問題がある。
本発明はかかる不都合を解消するためになされたものであり、節水を図ることができると共に、はつり作業効率の向上を図ることができ、しかも、汚濁水の処理コストの大幅な低減を図ることができる舗装表面のはつり方法及び装置を提供することを目的とする。
【0006】
【課題を解決するための手段】
かかる目的を達成するために、第1の発明に係る舗装表面のはつり方法は、舗装の表面に向けて圧力水を噴射して該舗装の表面をはつり、はつりにより生じた表層材を水と共に回収した後、該回収物を濾過して前記表層材を除去し、濾過後の水を舗装の表面に向けて噴射する圧力水に再利用することを特徴とする。
【0007】
第2の発明に係る舗装表面のはつり方法は、第1の発明において、前記圧力水を舗装表面上に形成された貯液部の液体中で噴射することによりキャビテーションを発生させ、このキャビテーションの衝撃力によって前記舗装表面のはつりを行うことを特徴とする
第3の発明に係る舗装表面のはつり装置は、舗装の表面に向けて圧力水を噴射して該舗装の表層のはつりを行う噴射手段と、はつりにより生じた表層材を水と共に回収する回収手段と、該回収手段によって回収された回収物を濾過する濾過手段と、濾過後の水を前記噴射手段に供給する水供給手段とを備えたことを特徴とする。
【0008】
第4の発明に係る舗装表面のはつり装置は、第3の発明において、前記噴射手段の噴射口の周囲を囲繞して内部に液体の貯留を可能にする貯液部を舗装表面上に形成し、該貯液部の液体中に前記噴射口を配置したことを特徴とする。
【0009】
【発明の実施の形態】
以下、本発明の実施の形態を図を参照して説明する。
図1は本発明の実施の形態の一例である舗装表面のはつり装置を説明するための説明図、図2は図1のA部断面図、図3は外箱の両端側のシール構造を説明するための一部を切り欠いた図、図4は図3のIV−IV線断面の一部を切り欠いた図、図5及び図6は本発明の他の実施の形態である舗装表面のはつり装置を説明するための説明図である。
【0010】
まず、図1〜図4を参照して、このはつり装置は、例えばトラック等の牽引車両100に可動アーム101を介して取り付けられる外箱10を備えており、外箱10は、車両100の進行方向の前後の側板11a,11bと、前後側板11a,11bの両端部を連結する左右の端板12a,12bとによって車両100の幅方向に長い略直方体状をなして上部及び下部が開口されている。左右の端板12a,12bには、車両100の進行方向の前後に配置された走行ロール13a,13bの各両端ロール軸14が支持されている。各走行ロール13a,13bの外周部には、それぞれゴム等の弾性体Gが被覆されている。
【0011】
図2に示すように、外箱10内には、内箱200が配置されている。内箱200は、前側走行ロール13aの前方に所定のすき間Cを介して配置された前側板201aと、後側走行ロール13bの後方に回収空間Pを介して配置された後側板201bと、前後側板201a,201bの上端部同士を連結する天板202とを備えて下部が開口されており、前後の側板201a,201b及び天板202は共に車両100の幅方向に延びて両端部が外箱10の端板12a,12bに固定されている。
【0012】
内箱200内の前側走行ロール13aと後側走行ロール13bとの間の上方には通水管15aが車両100の幅方向に沿って延在され、内箱200の後側板201bと外箱10の後側板11bとの間には通水管15bが車両100の幅方向に沿って延在されている。
通水管15aの上側部には水供給用管(水供給手段)203が天板202を貫通して接続されており、また、通水管15aの下側部には舗装表面hに向けて高圧水を噴射する噴射ノズル(噴射手段)17aが通水管15aの軸方向に略等間隔で設けられている。噴射ノズル17aは車両100の進行方向の後方側に斜めに延びて後側走行ロール13bの前方位置の舗装表面hに高圧水を吹き付けるようになっており、先端に設けられた噴射口Hが後側走行ロール13bの上面より下方に位置している。
【0013】
一方、通水管15bの上側部には水供給用管(水供給手段)204が接続されている。また、通水管15bの下側部には舗装表面hに向けて斜め前方に高圧水を噴射する噴射ノズル(回収手段)17bが通水管15bの軸方向に略等間隔で設けられている。噴射ノズル17bの舗装表面hへの吹き付け位置は、回収空間Pの若干後方とされている。
【0014】
通水管15aに接続された水供給用管203及び通水管15bに接続された水供給用管204はそれぞれ高圧水供給ポンプ(水供給手段)206a,206bを介して車両100に搭載された清水タンク206に接続されている。高圧水供給ポンプ206a,206bの駆動により、清水タンク206内の水が水供給用管203,204を介して通水管15a,15bに供給され、噴射ノズル17a,17bから高圧水が舗装表面hに向けて噴射されるようになっている。
【0015】
図3及び図4に示すように、走行ロール13a,13bの一方の各ロール端面と外箱10の端板12aとの間及び走行ロール13a,13bの他方の各ロール端面と外箱10の端板12bとの間にはそれぞれサイドカバー22が配置されている(図2ではサイドカバー22の図示を省略する。)。
サイドカバー22は、板状の本体部23と、該本体部23の下部に進行方向に沿って溶接等によって固定された丸棒部24とを備えており、該丸棒部24が舗装表面hに接触している。
【0016】
本体部23の走行ロール13a,13bの両端ロール軸14に対応する位置には上下方向に長い長穴23aが形成されており、該長穴23aには走行ロール13a,13bの両端ロール軸14が挿通されている。これにより、サイドカバー22の上下方向の移動が可能になって、凹凸の舗装表面hを走行する際に、丸棒部24が該凹凸に追従するようになっている。
【0017】
端板12aと一方のサイドカバー22との間には引張コイルばね25が介在されており、引張コイルばね25の上端はサイドカバー22の本体部23に取り付けられ、下端は端板12aに取り付けられている。
端板12bと他方のサイドカバー22との間にも同様に引張コイルばね25が介在されており、引張コイルばね25の上端はサイドカバー22の本体部23に取り付けられ、下端は端板12bに取り付けられている。これにより、各サイドカバー22を舗装表面h側に付勢して丸棒部24の舗装表面への密着性を高めるようにしている。なお、引張コイルばね25のばね定数を調整することにより、丸棒部24の舗装表面hへの接触圧力を調整することができる。
【0018】
そして、この実施の形態では、走行ロール13a,13b、外箱10の端板12a,12b及び各サイドカバー22によって内箱200の内部に水の貯留を可能にする貯液部Tを形成し、貯液部T内への水の供給は噴射ノズル17aから噴射された高圧水によって行うようにしている。
これにより、噴射ノズル17aの噴射口Hが水中に配置され、この状態で噴射ノズル17aの噴射口Hから舗装表面hに向けて高圧水を噴射することにより、貯液部T内の水と高圧水との間にキャビテーションが発生し、このキャビテーションの衝撃力により舗装表面hのはつりが行われる。
【0019】
はつりにより発生した表層材は貯液部T内に収容されて該貯液部T内の水と共に天板202の後側走行ロール13bの上方位置に接続された吸引ダクト(回収手段)207の吸引口208から吸引回収されると共に、回収しきれなかった表層材は噴射ノズル17bから噴射された高圧水の吹き付け圧によって水と共に回収空間Pの下方位置に集められ、該回収空間Pを介して吸引口208から噴射水と共に吸引回収される。
【0020】
吸引ダクト207の吸引口208は車両100の幅方向に沿って延びて内箱200内に開口しており、また、吸引口208の下方には吸引ノズル209が設けられている。なお、噴射ノズル17aの噴射口Hからの高圧水の噴射量は、吸引口208から貯液部T内の水が吸引回収されても噴射ノズル17aの噴射口Hが常に水中に配置されるように吸引ダクト207の吸引力との間で調整されている。
【0021】
図2に吸引口208から吸引回収される水と空気の流れを示す。図において破線矢印が空気の流れ、実線矢印が水の流れであり、空気はすき間C及び回収空間Pを通って吸引回収され、水は貯液部Tから吸引回収されると共に回収空間Pを通って吸引回収される。
図1を参照して、車両100には上述した清水タンク206の他に気水分離装置102が搭載されており、気水分離装置102には吸引ダクト207が接続されて吸引口208から吸引回収された回収物が投入されるようになっている。
【0022】
気水分離装置102は気体と液体とを分離する装置であり、装置102には排気ダクト103の一端が挿入されている。排気ダクト103の他端は外部に配置されて途中に吸引装置104が介装されており、吸引装置104の駆動により、吸引ダクト207に吸引力が付与されると共に、吸引ダクト207から気水分離装置102に投入された空気が排気ダクト103を介して排出されるようになっている。
【0023】
また、気水分離装置102の底部には配管105の一端が接続されており、該配管105の他端は清水タンク206に挿入されている。配管105にはポンプ107及び濾過装置(濾過手段)108が介装されており、従って、ポンプ107の駆動により、気水分離装置102の底部に収容された汚濁水は配管105を介して清水タンク206側に排出され、途中で濾過装置108によって濾過される。これにより、汚濁水に含まれた表層材が除去され、濾過後の水が再生水として清水タンク206に供給される。
【0024】
次に、かかる構成の舗装表面のはつり装置の作動を説明する。まず、吸引装置104の駆動により吸引ダクト207に吸引力を付与して内箱200内の空気を吸引することにより内箱200をある程度負圧にし、この状態で高圧水供給ポンプ206a,206bの駆動により、清水タンク206内の水を水供給用管203,204を介して通水管15a,15bに供給し、噴射ノズル17a,17bから舗装表面hに向けて高圧水を噴射する。そして、貯液部T内に水が溜まって噴射ノズル17aの噴射口Hが水中に配置された状態で車両100を前方に進行させる。
【0025】
このとき、噴射ノズル17aの噴射口Hから舗装表面hに向けて噴射された高圧水と貯液部T内の水との間にキャビテーションが発生し、このキャビテーションの衝撃力により舗装表面hのはつりが行われる。
はつりによって生じた表層材は貯液部T内に収容されて該貯液部T内の水と共に吸引ダクト207の吸引口208から吸引回収されると共に、回収しきれなかった表層材は噴射ノズル17bから噴射された高圧水の吹き付け圧によって水と共に回収空間Pの下方位置に集められ、該回収空間Pを介して吸引口208から吸引回収される。
【0026】
吸引ダクト207を介して吸引回収された回収物は気水分離装置102に投入され、回収空気が排気ダクト103を介して排出されると共に、ポンプ107の駆動により、気水分離装置102の底部に収容された表層材と水との混合汚濁水は配管105を介して排出される。そして、配管105を流れる汚濁水は途中で濾過装置108により濾過されて表層材が除去され、濾過後の水が再生水として清水タンク206に供給される。
【0027】
清水タンク206に供給された水は、上記同様にして、高圧水供給ポンプ206a,206bの駆動により、水供給用管203,204を介して通水管15a,15bに供給され、噴射ノズル17a,17bから舗装表面hに向けて高圧水として噴射される。
上記の説明から明らかなように、この実施の形態では、舗装表面hのはつりとはつりによって生じた表層材の水との混合汚濁水の吸引回収を同時に行うことができるので、はつり作業効率の向上を図ることができ、しかも、回収された汚濁水を濾過装置108により濾過して濾過後の水を噴射ノズル17a,17bに供給して高圧水として再利用しているため、節水を図ることができると共に、汚濁水の量が節水分だけ少なくなって汚濁水の処理コストの大幅な低減を図ることができる。
【0028】
また、噴射ノズル17aの噴射口Hから噴射された高圧水と貯液部T内の水との間に発生したキャビテーションの衝撃力により舗装表面hのはつりを行うようにしているため、路面から剥離した骨材等の飛散が防止されて安全性に優れると共に、はつり作業時の低騒音化を図ることができる。
更に、外箱10の長手方向の両端側をシールするサイドカバー22を上下方向に移動可能に配置して凹凸の舗装表面hを走行する際に丸棒部24が該凹凸に追従するようにし、しかも、引張コイルばね25によりサイドカバー22を舗装表面h側に付勢して丸棒部24の舗装表面hへの密着性を高めるようにしているので、丸棒部24と舗装表面hとの間から貯液部T内の水が外部に漏れるを抑制することができる。
【0029】
なお、上記実施の形態では、噴射ノズル17a,17bに高圧水を供給する水供給用管203,204を1本ずつ別々に設けているが、これに代えて、図5に示すように、水供給用管203及び水供給用管204を上流側で合流させて1本の水供給用本管205とし、該水供給用本管205に一台の高圧水供給ポンプ206aを介装して清水タンク206に接続するようにしてもよい。この場合、図6に示すように、噴射ノズル17bに高圧水を供給する水供給用管204に減圧手段120を介装し、噴射ノズル17bの高圧水を回収しきれなかったはつり後の表層材料の回収に必要な最低限の圧力設定にすれば、エネルギー節約の点で好ましい。
【0030】
また、上記実施の形態では、噴射ノズル17aから噴射される高圧水によって貯液部T内に水を供給するようにしているが、これに代えて、内箱200の天板202に水供給部(図示せず。)を設けて、この水供給部から貯液部T内に水を供給するようにしてもよく、或いは水供給部及び噴射ノズル17aの両方を用いて貯液部T内に水を供給するようにしてもよい。いずれにしても、水の供給量は、吸引ダクト207から貯液部T内の水が吸引搬送されても噴射ノズル17aの噴射口Hが常に水中に配置されるように吸引ダクト207の吸引力との間で調整される。
【0031】
更に、上記実施の形態では、噴射ノズル17aの噴射口Hから噴射された高圧水と貯液部T内の水との間に発生したキャビテーションの衝撃力により舗装表面hのはつりを行うようにしているが、必ずしもこのようにする必要はなく、噴射ノズルから舗装表面hに向けて超高圧水を噴射してその衝撃力で舗装表面hのはつりを行うようにしていもよい。
【0032】
【発明の効果】
上記の説明から明らかなように、本発明によれば、節水を図ることができると共に、はつり作業効率の向上を図ることができ、しかも、汚濁水の処理コストの大幅な低減を図ることができるという効果が得られる。
この場合、舗装表面上に形成された貯液部の液体中で圧力水を噴射してキャビテーションを発生させ、このキャビテーションの衝撃力によって舗装表面のはつりを行うことにより、路面上の骨材等の飛散が防止されて安全性に優れると共に、はつり作業時の低騒音化を図ることができる。

[0021]
FIG. 2 shows the flow of water and air sucked and collected from the suction port 208. In the figure, the broken line arrows indicate the flow of air and the solid line arrows indicate the flow of water. Air is sucked and collected through the gap C and the collection space P, and water is sucked and collected from the liquid storage portion T and passes through the collection space P. And collected by suction.
Referring to FIG. 1, in addition to the above-described fresh water tank 206, the vehicle 100 is equipped with a steam / water separator 102, and a suction duct 207 is connected to the steam / water separator 102 and sucked and collected from a suction port 208. The collected material is put in.

The other end of the exhaust duct 103 is arranged outside, and a suction device 104 is interposed in the middle. A suction force is applied to the suction duct 207 by driving the suction device 104, and air and water are separated from the suction duct 207. Air supplied to the device 102 is exhausted through the exhaust duct 103.
[0023]
One end of a pipe 105 is connected to the bottom of the steam / water separator 102, and the other end of the pipe 105 is inserted into a fresh water tank 206. The pipe 105 is provided with a pump 107 and a filtering device (filtering means) 108, and therefore the polluted water stored at the bottom of the steam separator 102 is driven by the pump 107 through the pipe 105. It is discharged to the 206 side, and is filtered by the filtration device 108 on the way. Thereby, the surface layer material contained in the polluted water is removed, and the filtered water is supplied to the fresh water tank 206 as reclaimed water.
[0024]
Next, the operation of the suspension device for the pavement surface having such a configuration will be described. First, the suction device 104 is driven to apply a suction force to the suction duct 207 to suck the air in the inner box 200, thereby bringing the inner box 200 to a certain negative pressure. In this state, the high-pressure water supply pumps 206a and 206b are driven. Thus, the water in the fresh water tank 206 is supplied to the water flow pipes 15a and 15b via the water supply pipes 203 and 204, and high pressure water is sprayed from the spray nozzles 17a and 17b toward the pavement surface h. Then, the water is accumulated in the liquid storage portion T, and the vehicle 100 is moved forward in a state where the injection port H of the injection nozzle 17a is disposed in the water.
[0025]
At this time, cavitation occurs between the high-pressure water jetted from the jet nozzle H of the jet nozzle 17a toward the pavement surface h and the water in the liquid storage portion T, and the pavement surface h is suspended by the impact force of this cavitation. Is done.
The surface layer material generated by the suspension is accommodated in the liquid storage part T, and is sucked and collected from the suction port 208 of the suction duct 207 together with the water in the liquid storage part T. The surface layer material that could not be recovered is the injection nozzle 17b. The water is collected together with water at a lower position of the recovery space P by the spraying pressure of the high-pressure water ejected from the air, and is sucked and recovered from the suction port 208 through the recovery space P.
[0026]
The collected material sucked and collected through the suction duct 207 is put into the steam separator 102, and the collected air is discharged through the exhaust duct 103, and at the bottom of the steam separator 102 by driving the pump 107. The mixed contaminated water of the stored surface material and water is discharged through the pipe 105. The polluted water flowing through the pipe 105 is filtered by the filtering device 108 on the way to remove the surface layer material, and the filtered water is supplied to the fresh water tank 206 as reclaimed water.
[0027]
In the same manner as described above, the water supplied to the fresh water tank 206 is supplied to the water pipes 15a and 15b via the water supply pipes 203 and 204 by driving the high-pressure water supply pumps 206a and 206b, and the injection nozzles 17a and 17b. To the pavement surface h.

As a result, it is possible to prevent the aggregates and the like from being scattered and to be excellent in safety, and to reduce noise during the lifting operation.
Furthermore, when the side cover 22 that seals both ends in the longitudinal direction of the outer box 10 is arranged to be movable in the vertical direction so that the round bar portion 24 follows the unevenness when traveling on the uneven paved surface h, In addition, since the side cover 22 is urged toward the pavement surface h side by the tension coil spring 25 so as to improve the adhesion of the round bar portion 24 to the pavement surface h, the round bar portion 24 and the pavement surface h are It is possible to suppress the water in the liquid storage part T from leaking to the outside.
[0029]
In the above embodiment, the water supply pipes 203 and 204 for supplying high-pressure water to the spray nozzles 17a and 17b are provided separately one by one, but instead of this, as shown in FIG. The supply pipe 203 and the water supply pipe 204 are merged on the upstream side to form one water supply main pipe 205, and a single high-pressure water supply pump 206 a is interposed in the water supply main pipe 205, and the fresh water It may be connected to the tank 206. In this case, as shown in FIG. 6, the surface layer material after the suspension in which the pressure reducing means 120 is interposed in the water supply pipe 204 that supplies high-pressure water to the injection nozzle 17 b and the high-pressure water from the injection nozzle 17 b cannot be recovered. If the minimum pressure required for the recovery of the pressure is set, it is preferable in terms of energy saving.
[0030]
Moreover, in the said embodiment, although the water is supplied in the liquid storage part T with the high pressure water injected from the injection nozzle 17a, it replaces with this and a water supply part is supplied to the top plate 202 of the inner box 200. (Not shown) may be provided so that water is supplied from the water supply part into the liquid storage part T. Alternatively, both of the water supply part and the injection nozzle 17a are used in the liquid storage part T. Water may be supplied. In any case, the amount of water supplied is the suction force of the suction duct 207 so that the injection port H of the injection nozzle 17a is always placed in the water even if the water in the liquid storage part T is sucked and conveyed from the suction duct 207. Coordinated with
[0031]
Furthermore, in the above embodiment, the pavement surface h is suspended by the impact force of cavitation generated between the high-pressure water jetted from the jet port H of the jet nozzle 17a and the water in the liquid storage part T. However, it is not always necessary to do this, and the high pressure water may be sprayed from the spray nozzle toward the pavement surface h, and the pavement surface h may be suspended by the impact force.
[0032]
