Abstract
Cavitation is produced through injection of pressurized water from an injection outlet of an injection nozzle 17a toward the pavement surface in liquid of a liquid storage part T1 formed on the pavement surface. A clogging object in a cavity of a pavement is isolated by impactive force of the cavitation, and the isolated clogging object is removed by suction with water.
Claims6
A method for processing a pavement surface wherein cavitation is produced through injection of pressurized water toward the pavement surface in liquid of a liquid storage part formed on the pavement surface, a clogging object in a cavity of a pavement is isolated by impactive force of the cavitation, and the isolated clogging object is removed by suction with water.
An apparatus for processing a pavement surface comprising an injection means injecting pressurized water toward the pavement surface and a suction means removing a clogging object by suction with water wherein the clogging object is isolated in a cavity of a pavement by injection of pressurized water of said injection means;
- wherein
- a liquid storage part is formed on the pavement surface wherein the liquid storage part surrounds an injection outlet of said injection means and liquid can be stored in the inside of the liquid storage part, and said injection outlet is placed in liquid of said liquid storage part.
A method for processing a pavement surface wherein cavitation is produced through injection of pressurized water toward the pavement surface in liquid of a liquid storage part formed on the pavement surface, the pavement surface is chipped by impactive force of the cavitation, and a separated object after chipping is removed by suction with water.
An apparatus for processing a pavement surface comprising an injection means injecting pressurized water toward the pavement surface and chipping the pavement surface, and a suction means removing a separated object after chipping by suction with water;
- wherein
- a liquid storage part is formed on the pavement surface wherein the liquid storage part surrounds an injection outlet of said injection means and liquid can be stored in the inside of the liquid storage part, and said injection outlet is placed in liquid of said liquid storage part.
