Description

AWATERING APPARATUS FOR AN ASPHALT CONCRETE PAVED ROAD}

The present invention relates to a water spraying device for ascon pavement, useful for preventing the deformation of the asphalt road pavement from overheating due to the convenience of cleaning the road and the overheating caused by the summer heat wave.

Asphalt-paved roads are occasionally sprayed with water, and the water is cleaned by sweeping dirt, dust and debris on the roadside.

Sprinklers are used to clean these waters on the asphalt roads. However, due to the lack of budget and the considerable difficulty in procurement of water supply and operation personnel, it was not possible to perform water cleaning on all jurisdiction asphalt roads.

In addition, ascon pavement is likely to cause deformation of ascon on the surface layer by overheating due to heat waves in summer. Ascon pavement roads in heavy lanes are particularly deformed due to overheating. Ascon pavement deformations take the place where the wheels have stepped on, and the seats next to them rise so much that they correspond to the amount that has gone down, and if the air temperature gradually decreases after the summer, Harden

The roughness of the rough asphalt asphalt pavement surface thus shaped acts as a detrimental factor for safe operation. Therefore, roads with severe unevenness of roads are cleaned by using special road maintenance vehicles equipped with power shredders during the fall season, which causes enormous obstacles in the communication of the vehicle while the roads are being cleaned up, and it is painful to blow dust, Also enormous.

In this regard, given the fact that there is a shortage of absolute numbers and not enough manpower, it is possible to efficiently clean the water on time without using water wheels and to prevent overheating of asphalt roads. You need to think deeply about it.

In the shopping districts and residential areas adjacent to the streets of small towns in the region, you can see the dirt from the streets by washing the dirt off the road and chilling the road during the summer. However, this method can work in some ways but is not suitable.

It is an object of the present invention to clean the soil and dirt on the road by simply sprinkling without mobilizing the sprinkler and professional personnel, and in the summer, ascon pavement sprinkler that can effectively suppress the deformation of the asphalt road pavement due to heat waves To provide.

In order to achieve the object of the present invention, the present invention utilizes a water pipe embedded in an asphalt road as a water supply pipe or embeds a separate water supply pipe, and a water supply pipe is embedded on the sidewalk formed along the road to connect the water supply pipe to a branch pipe. Water spray pipes are sprayed to the road, water holes are sprayed toward the road, manholes are installed on the side of the sidewalk where the water pipes and branch pipes meet, and water is cleaned during the daylight hours (about 1 to 2 hours from dawn) on the branch pipes in the manhole area Provides spraying device for Ascon pavement, which is configured to be sprayed by installing a solenoid valve controlled by a sensor and a controller to control the spraying of road surface cooling water at a time when the low temperature of the day is the highest during the summer. .

1 to 3, when a water pipe is buried on the asphalt concrete pavement 1, this is used as a water supply pipe 2, and in the case of an asphalt concrete pavement 1 where the water pipe is not buried, the water pipe 2 is used. Buried The water supply pipe 2 is parallel to the road direction of the asphalt concrete pavement 1.

If a water pipe (2) is selected instead of a water pipe, rainwater can be used as cooling water for asphalt roads by installing rainwater storage tanks for storing road water on sidewalks (3) and connecting water pipes (2).

A water pipe 4 is embedded on the sidewalk 3 and connected to the water supply pipe 2 with a branch pipe 5 at regular intervals. The water pipe 4 is of course also buried along the sidewalk 3.

A manhole 6 is provided where the water pipe 4 and the branch pipe 5 meet, and a solenoid valve 7 is provided on the branch pipe 5 in the manhole 6 region. The solenoid valve 7 controls the water from the branch pipe 5 to the auxiliary water supply pipe 4.

In addition, a sensor 12 and a control device 13 are installed in the facility pole 11 such as a pole, street lamp, and communication pole closest to the manhole 6 to be electrically connected to an external power source and the solenoid valve 7. The sensor 12 sprays the water for street cleaning for a predetermined time from dawn to winter for all seasons except the cold weather, and in the cold season, a sufficient amount to intermittently or wet the road surface from 2 pm to 4 pm, which is the highest temperature of low temperature. It sends a predetermined signal to the control device 13 to control the water to spray water to cool the road surface heated by the heat wave to cool the water. ) And by sensing the temperature of the atmosphere during the midday of the cold season to let the control device 13 to control the solenoid valve (7).

In the manhole 6, of course, the step 9 is provided so that the worker can climb up and down safely. Fortunately, however, if the manhole 6 is shallow and the valve 7 can be operated on the sidewalk 3, the step 9 can be omitted. Reference numeral 14 denotes a manhole cover.

Referring to FIG. 4, the water spray pipe 8 is embedded at regular intervals between the manhole 6 and another adjacent manhole 6. All water pipes 8 should have a nozzle 8a facing the driveway 1, the end of the nozzle (8a) in line with the road boundary stone 10 so as not to obstruct vehicle traffic.

Regardless of whether the furnace width is large or small, it is possible to cool the asphalt concrete pavement surface more effectively by making the watering distance of the nozzle 8a exceed the center line. To do this, the water supply pressure is increased or the spraying direction of the nozzle 8a is slightly inclined upwardly so as to draw a parabolic line to increase the spraying distance.

When the day is bright, the sensor 12 detects the amount of light in the sunshine and notifies the control device 13 that the morning is bright. The control device 13 immediately opens the solenoid valve 7 to spray water 15 at a suitable water pressure with the nozzle 8a, and operates the solenoid valve 7 to block the flow path at a predetermined time. . A worker on a road that is sprayed with water will sweep down in the rain or drive a brush car to remove dirt and dust from the road.

When the road surface of the asphalt concrete pavement (1) shows overheating due to the intense heat on a summer afternoon, the sensor 12, which senses the temperature of the air, sends a signal to the controller 13, and the solenoid valve 7 ) Will open. At this time, the surface of the asphalt concrete pavement (1) heated by solar heat is sprayed with cooling water to prevent the ascon layer from melting in the heat wave, not water spraying water.

After a predetermined time has elapsed while the cooling water is sprayed, the control device 12 closes the solenoid valve 7.

As such, the present invention can be automatically sprayed at any time of the day in the morning, at any time of the four seasons except for the ice machine, so that the water of the street is easily cleaned.

In addition, it is very effective in preventing the deformation of the asphalted asphalt road as it can be timely cooled by sprinkling the coolant during the midday of the cold season, so that it is timely cooled by the heat wave and tends to be deformed.
