DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for spraying high-pressure water onto, for example, a deposit such as gum sticking on a road surface, natural dirt (dust or the like) on a road surface, or a thin layer of concrete hanging on a road. The present invention relates to a washing vehicle equipped with a water recycling device that performs washing by suction and removal while washing.

[0002]

2. Description of the Related Art Conventionally, road surfaces such as roadways and sidewalks are cleaned by a cleaning system as shown in FIG. That is, in this cleaning system, high-pressure water is supplied from a high-pressure pump 102 connected to a water tanker 101 to a water blast 100 that is movable on a road R via a high-pressure hose 103. Blast 1
By jetting from a jet nozzle (not shown) of No. 00 onto the surface of the road R, for example, deposits and the like are removed.

[0003] A suspended substance containing deposits and the like removed by high-pressure water and the injected water are combined with a vacuum hose 10.
The air is sucked into the vacuum transport vehicle 105 through the vacuum transport vehicle 4, transported from the vacuum transport vehicle 105 to the vacuum vehicle 106, and stored in the vacuum tank 107. The water and the suspended substance stored in the vacuum tank 107 are transported by a vacuum truck 106 to, for example, a processing plant and are appropriately processed.

[0004]

However, in this cleaning system, water supplied from the high-pressure pump car 102 to the aqua blast 100 is stored in a vacuum tank 107 together with suspending substances, and is sent to a processing plant. Since the water is transported and processed, the water used at the cleaning site is in a disposable state and cannot be reused, and there is a problem that the water for cleaning in the water tank truck 101 cannot be effectively used. .

[0005] Further, a water tank truck 101, a high-pressure pump truck 102, a vacuum transport truck 105, and a vacuum truck 10 are used for cleaning work.
6, a total of four vehicles are required. Therefore, connection work of the piping system and the electric system of these vehicles, securing of a parking space for each vehicle, and the like are troublesome, and when water in the water tanker truck 101 runs out. Since the washing operation cannot be performed, it is necessary to always pay attention to the amount of water in the water tanker 101. In addition, there is a problem that it is difficult to efficiently perform a cleaning operation, for example, a large space is required for parking of each vehicle, and smooth traffic is easily hindered by the cleaning operation.

[0006] Further, the workers involved in the cleaning work include the operator m2 of the Aquablast 100, including the site supervisor m1,
At least five workers are required: a manager m3 for the high-pressure hose 103 and the vacuum hose 104, a manager m4 for the water tank truck 101 and the high-pressure pump truck 102, and a manager m5 for the vacuum transport truck 105 and the vacuum truck 106. However, there is a problem that the number of work steps is easily increased.

The present invention has been made in view of such circumstances, and a first object of the present invention is to provide a washing vehicle with a water recycling device that can reuse water used for washing at a washing site. In addition, a second object is to provide a washing vehicle with a water recycling device that can efficiently perform a washing operation and reduce the number of operation steps.

[0008]

Means for Solving the Problems In order to achieve the above object, an invention according to claim 1 of the present invention is a vehicle for cleaning a road surface, wherein at least a vehicle body has a carrier.
A water recycling device for separating water used for washing and a suspending substance is mounted, and the water separated by the water recycling device is reused as washing water at a washing site.

[0009] With this configuration, the water recycle device mounted on the cargo bed of the vehicle body, for example, cleansing water sprayed by aqua blast and suspending water containing adhering matter and the like removed by the water. The substances are separated at the cleaning site. The separated water is reused as washing water, and can be effectively used.

According to a second aspect of the present invention, there is provided a vehicle for cleaning a road surface, comprising: a water tank in which a predetermined amount of water is stored in a carrier of a vehicle body; and an aqua blast moving on a road. A high-pressure water generation pump that supplies high-pressure water from a water tank, a vacuum device that suctions water and suspended substances injected from aquablast, and a process for separating water and suspended substances sucked by the vacuum device A water recycling device, and the water separated by the water recycling device is returned to the water tank.

The invention according to claim 3 is characterized in that a loading space for aqua blast, working tools and the like is provided on a carrier of a vehicle body.

With this configuration, all the devices required for cleaning are mounted on the carrier of one vehicle, and the piping system and electric system of each device are connected in advance. Just by parking the vehicle at the site, the connection work of each device is eliminated, and the parking space is narrowed. For example, the cleaning work can be performed efficiently, and the number of work steps can be reduced, for example, since only one vehicle administrator can be used. Further, the mounting space for the aqua blast and work tools and the like provided on the carrier of the vehicle body prevents the tools and the like from being lost, for example.
