Description
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, .
The present invention minimizes the repulsive force of a cable pulling force by preventing a plurality of cables from coming into close contact with each other in a process of pulling a plurality of cables into a wave tube, The present invention provides a cable laying method of a corrugated pipe using an underground cable corrugated pipe compartment, which is designed to facilitate replacement of the cable.
In order to accomplish the above object, a cable laying method of a corrugated pipe using an underground cable corrugated tube compartment of the present invention is a cable laying method of a corrugated pipe for constructing a corrugated pipe in the ground and installing a cable in a corrugated pipe A plurality of compartments each having a first hooking hole and a first connecting hole at one end thereof and a second hooking hole and a second connecting hole at the other end so as to correspond to the first hooking hole and the first connecting hole, A first step of connecting the pulling wires to the first hooking holes respectively provided in the plurality of the partitioning panels of the wave tube sectioning section, the panel including a radial tube section dividing section; A first connection hole provided at one end of each of the plurality of partition panels of the corrugated pipe section, and a second connection hole provided at each end of the plurality of partition panels of the corrugated pipe section so as to correspond to the first connection hole, fair; A third step of placing the corrugated tube compartment in which the pulling wire and the connecting wire are connected to each other so that the pulling wire connected to the first hooking hole is inserted into the corrugated tube at one side of the corrugated tube buried in the ground; A fourth step of pulling the pulling wire connected to the first hooking hole of the wave tube sectioning section located at one side of the wave tube by the third step into the other side of the wave tube tube to insert the wave tube tube section into the inside of the wave tube tube; After the corrugated pipe section is inserted into the corrugated tube by the fourth step, the connecting wire connecting the first connecting hole and the second connecting hole is loosened, the cable is connected to one side of the connecting wire unwound from the second connecting hole, And a fifth step of pulling the other side of the connection wire loosened from the connection hole to insert a cable into each of the plurality of partition panels provided in the corrugated pipe section.

The present invention is characterized in that a wave tube section dividing a single wave tube section is first inserted into a wave tube before cable installation and then a cable is installed in the inside of the wave tube so that a plurality of cables are partitioned by the wave tube section, It is possible to minimize the load tension on the cable, and it is possible to greatly improve the work efficiency as well as the installation workability of the cable. Also, since the cable is divided in each of the corrugated pipe sections, Can be easily achieved.
