Description

Technical Field [0001] The present invention relates to a cable installation method of a corrugated pipe using a compartment tool,

The present invention relates to a cable laying method of a corrugated pipe using an underground cable corrugated pipe compartment, and more particularly, to a cable laying method using a corrugated corrugated pipe compartment in which a plurality of cables are installed, And more particularly, to a cable laying method of a corrugated pipe using an underground cable corrugated pipe section so as to minimize workability and work efficiency.

Generally, in the construction of electric wire or communication cable for electric power supply, in the past, electric pole was used to install the electric wire in the air. However, in order to utilize the road space and for safety and beauty, a wave tube was buried in the ground, A wire or a communication cable is installed inside the terminal.

Conventionally, a method of laying a cable in a ground will be briefly described. A wire is first drawn from one side of a corrugated tube buried in the ground to the other side to draw the wire in the other direction, then the cable is connected to the drawn wire, So that the cable is pulled into the inside of the corrugated tube, and the cable is laid.

In this case, as a means for pulling the cable, a cable is pulled directly by a pulling force or a pulling device such as a pulling device is used to pull the cable.

On the other hand, the buried cable usually has three or four phases such that a plurality of cables are installed in one corrugated tube. In the process of pulling the plurality of cables, the cable and the cable come into contact with each other inside the corrugated tube, There is a problem in that the load tension is largely generated.

That is, since most cables are provided with an outer cover made of rubber or synthetic resin on the surface thereof, the surfaces of the cables come into contact with each other during the pulling operation for pulling the cable into the inside of the wave tube, The load of the cable is transmitted to the pulling device as it is, and the excessive pulling of the pulling device causes a problem that the rate of occurrence of the failure of the pulling device is increased.

In addition, even if any one of the cables installed in the inside of the corrugated tube is to be replaced, the cables remain in close contact with each other inside the corrugated tube, so that the cable to be replaced is replaced And then a plurality of cables are drawn into the inside of the corrugated pipe to lay the corrugated pipe again, resulting in a reduction in work efficiency and a significant delay in the working time.

In the prior art, a method of installing an underground low-voltage cable and a cable 4 drum selecting apparatus using a cable 4 drum selecting apparatus, which is disclosed in Patent Document 10-1159700, has been proposed. This is because four winding drums, Disposing a digital puller having a data collecting device for collecting data during installation of a roller and a low-tension cable rotatably driven corresponding to the four winding drums; Connecting a low-tension cable of each of the four winding drums to a double-folded rope installed on a roller of the digital puller, a step of connecting a double-braided rope to the roller of the digital puller, The pulling-in tension, the pulling-in speed, and the pulling-in speed during the low-voltage cable laying of the four winding drums While checking the distance of the wound double bonded brake rope on the roller consists of the step of laying each of said low-voltage cable winding drum 4 in the ground.

This conventional technique has the advantage that four cables can be simultaneously pulled by the four drum selection apparatus, while a plurality of cables are in close contact with each other in the process of drawing a plurality of cables into the inside of the wave tube, The problem that is caused by this problem is still not resolved.

In order to solve the problem of installing a conventional cable in the ground, the Applicant has found a subdivision of a submerged cable wave tube as a registered patent No. 10-1550562, which is divided into a compartment defined by a compartment dividing the inside of the corrugated wave tube The cable can be embedded in each of the space portions, so that even if a plurality of cables are embedded in one wave tube, the cables are positioned in the compartment space, It is possible to remove the cable only for replacement and repair work, which can greatly shorten the working time due to cable replacement and repair work, and greatly improve work efficiency.

Accordingly, there is a problem in that a plurality of cables are brought into close contact with each other in the process of entering the inside of the corrugated pipe by providing a method of installing the cable by using the underground cable corrugated tube compartment, which is the registered patent No. 10-1550562, .
