The rotating shaft 61 is connected to a hydraulic motor 62 that is a rotational driving means, and is driven to rotate in the traveling direction of the function recovery vehicle 1, that is, in the direction opposite to the rotating direction of the traveling tire 11 (clockwise in the drawing). (See FIG. 4).

このように、吸引口５０の後方近傍位置には、機能回復車１の走行タイヤ１１の回転方向と反対方向に回転する回転ブラシ６０が備えられているので、吸引口５０に吸引されずに残留する懸濁液Ｄ及び舗装面Ｒの塵埃等を回転ブラシ６０によって吸引口５０側に掻き上げて全ての懸濁液Ｄを吸引することができ、舗装面Ｒに洗浄水Ｗの水溜まりを残すことがない。   As described above, the rotary brush 60 that rotates in the direction opposite to the rotation direction of the traveling tire 11 of the function recovery vehicle 1 is provided in the vicinity of the rear side of the suction port 50, so that it remains without being sucked into the suction port 50. The suspension D and the dust on the pavement surface R can be sucked up to the suction port 50 side by the rotating brush 60 to suck all the suspension D, leaving a puddle of cleaning water W on the pavement surface R. There is no.

このように構成された排水性舗装の機能回復車１によって排水性舗装面Ｒの目詰まりを除去するには、まず、操作盤１４によって移動手段２を作動させ、油圧シリンダ２１のピストンロッド２１ｂを伸ばしてパンタグラフ機構２０を舗装面Ｒ側に移動させると共に、洗浄装置３を洗浄作業位置に移動させる。このとき、キャスタ７０が舗装面Ｒに接地して回転ブラシ６０と舗装面Ｒとの接触状態が適正な状態に維持される。   In order to remove the clogging of the drainage pavement surface R by the drainage pavement function recovery vehicle 1 configured as described above, first, the moving means 2 is operated by the operation panel 14, and the piston rod 21b of the hydraulic cylinder 21 is moved. The pantograph mechanism 20 is extended and moved to the pavement surface R side, and the cleaning device 3 is moved to the cleaning work position. At this time, the caster 70 contacts the pavement surface R, and the contact state between the rotating brush 60 and the pavement surface R is maintained in an appropriate state.

次に、ポンプユニット１２の高圧水ポンプ１２ａがポンプ駆動用エンジン１２ｂの駆動に伴って駆動し、水タンク１３内の洗浄水Ｗを高圧水ポンプ１２ａ内に供給する。この高圧水ポンプ１２ａに供給された洗浄水Ｗは、一定の圧力と流量まで上昇した後、供給管１３ｊを通って洗浄装置３へ供給される。そして、供給された超高圧洗浄水Ｗが回転軸４５、回転ヘッド４６及び高圧パイプ４７を通ってノズル体４８の先端から噴射される。この超高圧洗浄水Ｗの噴射に伴って噴射水周辺の大気が巻き込まれてエアーブローを兼ねるので、少水量にて洗浄することができ、長時間の洗浄が可能となる。また、この際、洗浄ノズル４１，４２は、洗浄装置本体３０に内蔵されたエアーモータ３１によって一定速度で回転される。   Next, the high-pressure water pump 12a of the pump unit 12 is driven as the pump driving engine 12b is driven, and the wash water W in the water tank 13 is supplied into the high-pressure water pump 12a. The cleaning water W supplied to the high-pressure water pump 12a rises to a certain pressure and flow rate, and then is supplied to the cleaning device 3 through the supply pipe 13j. The supplied ultra-high pressure cleaning water W is jetted from the tip of the nozzle body 48 through the rotary shaft 45, the rotary head 46 and the high-pressure pipe 47. As the ultra-high pressure washing water W is jetted, the atmosphere around the jet water is entrained and serves as an air blow, so that it can be washed with a small amount of water and can be washed for a long time. At this time, the cleaning nozzles 41 and 42 are rotated at a constant speed by the air motor 31 built in the cleaning apparatus main body 30.

このように洗浄ノズル４１，４２を回転させつつ、ノズル体４８から超高圧洗浄水Ｗを噴射することで洗浄ノズル４１，４２の下方に位置する排水性舗装面Ｒが洗浄ノズル４１，４２の回転軌跡Ｓに沿って円弧状に洗浄される。この状態で、機能回復車１が走行すると、まず、第１の洗浄部４３の３つの洗浄ノズル４１によって排水性舗装面Ｒを３本の帯状に洗浄して、舗装面Ｒ内の目詰まり物（土砂等）を吹き上げる。次いで、第１の洗浄部４３の後方に位置する４つの洗浄ノズル４２（第２の洗浄部４４）によって、第１の洗浄部４３の洗浄ノズル４１間の不完全洗浄部分を第２の洗浄部４４の４つの洗浄ノズル４２によって洗浄して、舗装面Ｒ内の目詰まり物（土砂等）を吹き上げる。よって、第１の洗浄部４３に第２の洗浄部４４が追従して排水性舗装面Ｒを洗浄することにより、排水性舗装面Ｒの洗浄を確実にすることができる。   The drainage pavement surface R located below the cleaning nozzles 41, 42 is rotated by rotating the cleaning nozzles 41, 42 by jetting the ultra-high pressure cleaning water W from the nozzle body 48 while rotating the cleaning nozzles 41, 42. Cleaning is performed in an arc along the trajectory S. In this state, when the function recovery vehicle 1 travels, the drainage pavement surface R is first washed into three strips by the three cleaning nozzles 41 of the first cleaning unit 43, and the clogged material in the pavement surface R is clogged. Blow up (such as earth and sand). Next, the four cleaning nozzles 42 (second cleaning unit 44) located behind the first cleaning unit 43 remove the incomplete cleaning part between the cleaning nozzles 41 of the first cleaning unit 43 to the second cleaning unit. Cleaning is performed by the four cleaning nozzles 42, and the clogged material (such as earth and sand) in the paved surface R is blown up. Therefore, the 2nd washing | cleaning part 44 follows the 1st washing | cleaning part 43, and the washing | cleaning of the drainage pavement surface R can be ensured by wash | cleaning the drainage pavement surface R.

そして、洗浄ノズル４１，４２から噴射される高圧洗浄水Ｗによって吹き上げられた目詰まり物（土砂等）を含む懸濁液Ｄはブロワ１３ｃの駆動によって生じる吸引力によって吸引口５０から吸引ダクト５１を介して水タンク１３内に回収される。また、吸引口５０に吸引されずに残留する懸濁液Ｄ及び舗装面Ｒの塵埃等は、走行方向と反対方向に回転する回転ブラシ６０によって吸引口５０側に掻き上げられて全て吸引口５０に吸引される。   Then, the suspension D containing clogged materials (such as earth and sand) blown up by the high-pressure washing water W sprayed from the washing nozzles 41 and 42 passes through the suction duct 51 from the suction port 50 by the suction force generated by driving the blower 13c. Through the water tank 13. Further, the suspension D remaining without being sucked into the suction port 50, dust on the pavement surface R, and the like are scraped up to the suction port 50 side by the rotating brush 60 that rotates in the direction opposite to the traveling direction, and are all sucked into the suction port 50. Sucked into.
