Description

  The present invention relates to a function recovery vehicle for drainage pavement.

  In recent years, drainage pavement is being applied to general roads and highways. Here, drainage pavement means a pavement with a gap that can be drained on the running surface. By draining rain water on the road surface through the gap during rain, the hydroplaning phenomenon of the traveling vehicle is prevented or the splash is suppressed. At the same time, it has a function of reducing tire noise during vehicle travel.

  However, such drainage pavement has a problem that earth and sand or dust is easily clogged in the gaps on the running surface, and the drainage performance, noise reduction performance, and the like are deteriorated.

  Therefore, as a means for recovering the function of the drainage pavement, there is a pavement surface treatment apparatus provided with a spraying means for injecting pressure water toward the drainage pavement surface to treat the pavement surface. A plurality of injection ports arranged in a zigzag shape in plan view and formed so that the sprayed areas against the pavement surface do not interfere with each other by pressure water injected from the plurality of injection ports (for example, patents) Reference 1).

Also, the road surface is cleaned by jetting a high-pressure jet while projecting downward from the chassis of the washing vehicle and rotating or reciprocatingly rotating a blast nozzle divided into two sides and two forks with a predetermined radius. Is known (see, for example, Patent Document 2).

  However, the former, that is, the one described in Japanese Patent Application Laid-Open No. 2003-129415 has a structure in which a plurality of injection ports of the injection means are arranged in a zigzag shape in plan view so that the spraying ranges on the pavement surface do not interfere with each other. Therefore, there is a problem that the cleaning of the portion where the pressure water spraying range does not interfere becomes incomplete. In addition, there is a problem that a large number of injection ports must be formed in order to reduce incompletely cleaned portions.

  In the latter case, that is, the one described in Japanese Patent Application Laid-Open No. 2003-306915, it is possible to clean a wide range by turning the blast nozzle divided into two forks, but the two blast nozzles are installed side by side. Due to the structure, there is a problem that cleaning between the blast nozzles is incomplete.

  Moreover, since the thing of Unexamined-Japanese-Patent No. 2003-129415 is in the state where the injection port of the injection means was always close to the pavement surface, there is a problem that it interferes with normal running other than cleaning work. Moreover, although the thing of Unexamined-Japanese-Patent No. 2003-306915 is provided with the raising / lowering means which can move to the up-down direction in order to avoid the obstruction of a road surface, since the washing | cleaning apparatus always protrudes ahead of the vehicle body also in this There is a problem that hinders normal driving.

A plurality of cleaning units having a plurality of cleaning nozzles, wherein the rotation center of the cleaning nozzle in the adjacent cleaning unit and the rotation center of the cleaning nozzle in the opposite row are formed at a shifted position. (Claim 1).

  In this invention, the anti-scattering body comprises a substantially cylindrical main body that surrounds the outer side of the rotation trajectory of each cleaning nozzle, and a flexible road surface contact member that is attached to the lower end opening of the main body. Further, the anti-scattering body may be provided with a frame-shaped main body that surrounds the outer side of the plurality of rows of cleaning portions, and a flexibility that is attached to the lower end opening of the main body. You may comprise with the road surface contact member which has (Claim 3).

  In addition, it is preferable that the scattering prevention body is provided with a suction port for sucking the washing water sprayed inward of the scattering prevention body and the earth and sand of the drainage pavement surface (Claim 4).
