And a function recovery device for recovering such a function.

る。2. Description of the Related Art As an example of a pavement having a water permeable function,
Drainage pavement is known. This drainage pavement ensures a high porosity in the surface layer of the pavement, and the base layer and the lower part of the pavement are made impermeable by using an asphalt mixture or a cement-based slab, so that it can be poured onto the road surface. Installed on the side of the road surface through the voids in the surface layer without letting rainwater, etc. penetrate into the roadbed or roadbed located below, and without letting these rainwater, etc. flow out or stay on the road surface. It drains the water down the drain.

工延長の急激な伸びを示している。That is, in this drainage pavement, the surface layer portion has a porosity of, for example, about 15 to 25% and 1 × 10 −2.
It has a water permeability of about 1 × 10 -1 , and its drainage function causes it to splash due to water splashes in the case of rain, etc., or to the splashes generated from the tires that rotate when the vehicle runs at high speed on a wet road surface. Smoke phenomenon, which is a phenomenon that causes poor visibility, or hydroplaning phenomenon, which causes a water film between the tire and the road surface to eliminate slip resistance. When tires come into contact with the road surface, it absorbs and reduces the tire pumping sound, which is the popping sound that is generated when the air compressed by the tread is suddenly released from the groove, which improves the comfortable running performance of the vehicle and the improvement of the roadside environment. It is possible to achieve this, and due to such superiority, it has shown a rapid increase in construction extension for the past several years.

るようになってきている。The drainage pavement is mainly composed of coarse aggregate in order to secure its high porosity and water permeability, and the durability and durability of the water permeability of the pavement are maintained. You need to be careful. Factors causing such deterioration in durability and water permeability are the scattering and crushing of aggregates caused by the weight of the vehicle and vibrations during driving, or dust and earth and sand particles clogging the voids. Although there is clogging that causes blockages, among these, regarding scattering and crushing of aggregates, development of a special binder with high viscosity and high performance for connecting aggregate particles, and examination during formulation design of asphalt mixture As a result, it has become possible to avoid them effectively.

る。On the other hand, it is difficult to prevent clogging in advance because the cause thereof is due to an external factor such as sand dust, and the functional failure due to such clogging is described above. Not only drainage pavements, but also various pavements with water permeability, such as water permeability pavements that make sidewalks water-permeable so that rainwater on the road surface can penetrate the roadbed or subgrade. This is a problem common to the body.

As such a method, conventionally, for example, , A method of blowing high-pressure water or compressed air onto the pavement, a method of sucking cleaning water, dust, etc. by vacuum, a method of adding vibration to the pavement, or a chemical solution such as hydrogen peroxide solution or a surfactant. Methods have been used in which the clogging material is chemically washed and removed using a kind.

い。However, according to the above-mentioned conventional method for removing clogging such as dust and earth and sand particles, in the method for blowing high-pressure water or compressed air onto the pavement or sucking it up by vacuum, In addition to the risk of damaging the pavement due to strong external effects, it is a work from the pavement surface, so it is blocked by the pavement on the surface part, so high pressure water and compressed air are not enough inside the pavement. The fact is that there is a limit to its application because it cannot be spread to all areas. Further, even if these operations are performed while applying vibration to the pavement, not only will the pavement be further damaged, but the improvement of the cleaning effect cannot be expected so much due to the block of the pavement on the surface portion.

を容易に修復することができる。According to the function recovery method of the present invention, when the cleaning water is ultrasonically vibrated while being supplied to the clogged pavement, the cleaning water and the particles constituting the pavement are separated from each other. It will cause vibration at high frequencies. In the process, cavitation occurs in the wash water that has penetrated into the interior of the pavement through the voids to the deep parts and narrow spaces of the complex shape, and energy is generated when the air bubbles are destroyed, and Contamination such as dust adhering to the constituent particles is forcibly stripped off and removed. That is, by such an action, as long as the wash water permeates and penetrates into the voids, even the clogging occurring at the deep position inside the pavement can be removed to easily restore the water permeability function. be able to.

The cleaning water sent from the cleaning water supply means will be stored in the water receiving mold that constitutes the water receiving portion, with the surface of the pavement serving as the bottom surface, and at a predetermined water depth that allows contact with the ultrasonic oscillator. , Ultrasonic vibration is generated by the action of the ultrasonic oscillator supported by the support member, and is also subjected to the action of hydrostatic pressure, while penetrating deep into the inside of the pavement along the void while removing the deposits. . In addition, the cleaning water containing the removed deposits can be absorbed by the suction force from the suction duct.
It moves along the void of the pavement in which the clogged state has been repaired, reaches the opening of the suction duct on the surface of the pavement, and is fed to the wash water recovery tank via this suction duct and is discharged. The water receiving mold is appropriately replenished with the cleaning water from the cleaning water supply means so that the predetermined water depth inside the water receiving mold is maintained.
