Description

[0001] The present invention relates to a road electric resistivity investigation apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road electrical resistivity survey apparatus, and more particularly, to a road electrical resistivity survey apparatus which is pulled by a running vehicle and continuously conducts a resistivity test on roads.

Roads on which many vehicles travel are always subjected to heavy loads or impacts due to the running resistance of the vehicle and the weight of the vehicle, and grounds under the roads are subject to cavitation or the like.

In order to ensure the safe operation of the vehicle, it is necessary to perform an inspection of the road surface and the ground to measure the state of the road.

As an existing road inspection method, there is an electrical resistivity inspection method in which an electrode is provided on the road surface of a road, and a predetermined current is applied through the electrode.

In the above method, since the electrode is installed on the road surface, the road surface is damaged in some way for the installation of the electrode. In particular, when electrodes are installed on paved roads, road pavement is damaged. In this case, even if the paved road is remodeled, it is highly likely that the second-order third-order failure occurs, so that the conventional electric resistivity probe electrode portion causes many problems on the road. Also, it is also inefficient to install and disassemble the peg-type electrode on the packed road because it requires a lot of time and labor.

In addition, since the inspection can be performed only on the position where the electrode is installed on the paved road, the inspection range is limited.

As prior art to the present invention, it is possible to exemplify the registered patent 10-1456565 and the patent publication 1020030021503.

The connecting ring may have a semicircular shape and may include a pair of unit rings, one end of which is hinged and the other end of which is fastened to each other.

The inner diameter of the connection ring of the electrode disposed on the main rod may be larger than the diameter of the valley portion of the main rod and smaller than the diameter of the wrinkles of the main rod.

The inner diameter of the connection ring of the electrode disposed in the extension rod may be larger than the diameter of the valley portion of the extension rod and smaller than the diameter of the corrugation of the extension rod.

The trailer 110 includes a trailer body 111 having a predetermined shape, a wheel 112, and a pulling ring 114.

The trailer main body 111 has a predetermined size and shape required by the user. On the trailer main body 111, the following components can be mounted.

The wheels 112 are disposed on both sides of the trailer main body 111 to allow the trailer main body 111 to travel. When the trailer main body 111 is parked, auxiliary wheels 113 having a predetermined size are provided at a front lower portion of the main body 111 in order to prevent the traction ring 114, which will be described later, Can be added.

The traction loop 114 is disposed forward of the trailer body 111 and is connected to a running vehicle so that the trailer 110 can be towed by the vehicle.

The GPS receiving unit 120 is disposed on the trailer 110 and continuously receives and outputs position information along the traveling path of the trailer 110 while the trailer 110 is running.

The electrical resistivity inspecting unit 130 is disposed on the trailer 110 and performs an electrical resistivity test on the road while the trailer 110 is being towed and outputs the inspected value.

The general construction of the electrical resistivity inspection apparatus and the inspection method using the electrical resistivity inspection apparatus are well known and known in the art, such as that disclosed in the '10 Resistance Resistance Investigation Apparatus and Method for Investigation of Electrical Resistance Using the Resistivity Investigation Method' .

The electrical resistivity test part 130 used in the present invention includes a connection rod 132 and a plurality of electrodes 140.

The connecting rod 132 has a predetermined length and diameter and is disposed at the rear lower portion of the trailer 110.

On the connection rod 132, an electrode 140 described later may be disposed.

4 is a perspective view illustrating an operation of the connection rod used in the present invention. Referring to FIG. 4, the connection rod 132 is configured to be variable in length.

The connection rod 132 includes a main rod 134A and an extension rod 134B.

The main rod 134A has a predetermined length and diameter, and provides a space in which an extension rod 134B described later can be disposed.

The main rod 134A may be a corrugated pipe having a predetermined height on the outer circumferential surface and formed with corrugations uniformly protruded.

The extension rod 134B has a predetermined length and a diameter, and can be inserted or projected at both ends of the main rod 134A, respectively.

Since the extension rod 134B is protruded or inserted at both ends of the main rod 134A, the overall length of the connection rod 132 can be varied.

The extension rod 134B may be a corrugated pipe having a predetermined height on the outer circumferential surface and formed with a constant corrugation.

Further, it is preferable that the main rod 134A and the extension rod 134B are made of a non-conductive material.

A plurality of electrodes 140 are arranged on the connection rod 132 at regular intervals. The number of the electrodes 140 to be arranged may vary depending on the needs of the user.

The electrode 140 is rotatably disposed on the connection rod 132, and one end thereof is contacted with the road surface so as to perform an electrical resistivity test. The electrode 140 is connected to a storage unit 150, which will be described later, by a signal line (not shown).

The configuration of the electrode 140 will be described in more detail.

5 is a perspective view showing an example of the configuration of an electrode used in the present invention.

Referring to FIG. 5, the electrode 140 includes a connection ring 142 and a unit electrode 146.

The connecting ring 142 is in the shape of a ring having a predetermined diameter and is disposed in the valley portion in the corrugation on the outer circumferential surface of the main rod 134A or the extending rod 134B.

6 is a perspective view showing various examples of electrodes used in the present invention.

Referring to FIG. 6, the length of the unit electrode 146 included in the electrode 140 is the same, and the inner diameter of the connection ring 142 is formed as needed.

That is, the connection rod 132 in which the electrode 140 is disposed includes the main rod 134A and the extension rod 134B, and the diameter of the main rod 134A is formed to be larger than the diameter of the extension rod 134B .

The electrode 140A disposed on the main rod 134A and the electrode 140B disposed on the extension rod 134B are arranged such that the inner diameter of the connection ring 142 is larger than the diameter of the main rod 134A and the extension rod 134B It can be understood that they are formed differently so as to correspond to each.

The inner diameter of the connecting ring 142 is made larger than the diameter of the valley of the main rod 134A or the extending rod 134B but smaller than the wrinkle height of the main rod 134A or the extending rod 134B, (134A) or the extension rod (134B) so as not to be separated from the rod.

Referring again to FIG.

The connecting ring 142 includes a pair of unit rings 144.

The unit ring 144 has a semicircular shape, and one end of the pair of unit rings 144 can be hinged to each other, and the other ends can be fastened to each other.

The use of the unit ring 144 is done as follows.

That is, the user releases the engagement of the unit ring 144 and rotates about the hinge connection portion of the unit ring 144 so that the pair of unit rings 144 are opened. Thereafter, the user places the unit ring 144 at a predetermined position of the main rod 134A or the extension rod 134B, and the end of the unit ring 144 is fastened to each other, so that the electrode 140 is fixed.

The unit electrode 146 is in the form of a rod having a predetermined length and is connected to one side of the connection ring 142.

2, the length of the unit electrode 146 is longer than the distance from the connecting rod 132 to the ground so that the end of the unit electrode 146 is pulled from the ground when the trailer 110 is traveling . Therefore, even when the height of the road surface is non-uniform during traveling of the trailer 110, the contact between the end of the unit electrode 146 and the road surface can be maintained.

The storage unit 150 stores the position information output from the GPS receiver 120 and the electrical resistivity measurement values output from the electrical resistivity testing unit 130.

The output unit 160 may output the location information and the electrical resistivity measurement values stored in the storage unit 150 in a manner required by the user and display the information.

The output unit 160 can output the traveling path and the resistivity measurement value by display, printing, or the like.

The present invention is characterized in that the vehicle is towed by a running vehicle and can continuously inspect the lower part of the road by the electrical resistivity test method. A resistivity test can be performed.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
