The present invention is to protect underground buried pipelines such as electricity, communication cables and gas, waterworks buried in the ground, more specifically, the pipelines buried in the ground is provided with a multi-protector made of a separate reinforced concrete block structure, By constructing underground pipelines such as electricity, communication cables, gas, and water supply using the multi-protector, underground pipes such as electricity, communication cables, gas, and water supply are carried out in carrying out the excavation work for underground laying and facility repair work. When excavating the location, the capsule that emits pigments and odors explodes and quickly recognizes that underground pipes are buried to the driver of the excavator, and the underground pipes such as electric, communication cables and gas, water supply, etc. Functionality that improves the safety of underground pipelines embedded in the ground by preventing damage in advance Using multi-protector to inertia, and it relates to a construction method of underground pipelines.

The undergroundization of the distribution line in Korea began in 1973 by distributing the distribution line, which was intricately installed from Hyoja-dong to Gwanghwamun, in the rear alley and relocating the electric poles along the main road to the back alley and supplying low voltage cables to the nearby customers from the main transformer. Since then, it has been planned and expanded.

In 1961, Gyeongsung Electricity, Namsun Electricity, and Chosun Electricity were merged into a single electric power company, and the construction of 22kV underground distribution lines soared as the demand for electricity increased, reaching a total length of 40 km. As the load density in the downtown area increased rapidly, such as redevelopment and the enlargement of buildings, the underground business began in earnest.

In September 1975, the Seoul Metropolitan Government's four main gates of the main four major gates were held in Seoul from 1977 to 1981 through a meeting of executives from related departments under the direction of the president to overhaul the complex overhead lines (power lines and telephone lines) along the main four major roads in Seoul. The underground project was implemented in full scale on the 32 km road, and the underground plan was prepared for the 1986 Asian Games and the 1988 Seoul Olympic Games. Since 1986, six regional metropolitan cities, including the central part of Seoul, have been selected and implemented.

Since the Seoul Olympics were successfully held in 1988, it has been actively developed in the name of supporting the national policy, and has recently been expanded to various areas such as new cities and industrial complexes.

In addition, as the city is developed and a new development complex is being built, the proportion of undergrounding is gradually increasing.The city planners have started to build joint districts in the development complex from the beginning for the purpose of beautifying the urban environment, traffic congestion due to road duplication, uncomfortable civil life, and budget reduction. It is being applied according to urban planning to build construction and power lines underground.

On the other hand, underground distribution lines buried in the ground as described above is buried in the ground spaced a certain depth from the ground, it is also possible to ensure the safety and heat insulation.

However, as the construction of underground distribution lines increases as mentioned above, the frequency of line accidents also increases gradually. The main cause of such accidents is cable failure, which is a high proportion of 80% of the total. Half of them are due to cable trauma, and if you look at the average (157) failures of underground equipment over the three years,

* Breakdown by Equipment

Cable failure: 125 cases (80%), switch breakdown: 19 cases (12%), transformer failure: 13 cases (8%),

* Failure by Cause

Trauma failure: 80 cases (51%), deterioration failure: 51 cases (32%), other cases: 26 cases (17%).

The main cause of the traumatic underground cable trauma is to carry out the digging work to bury the additional underground lines in addition to the underground cables already laid, or to bury and repair the underground burying facilities such as separate water and sewage pipes. Such excavation works, in general, excavate the ground quickly and easily with excavators and other equipment.

As such, in the process of the excavation work, the driver of the excavator does not see underground pipelines such as electric, communication cables, gas, and waterworks buried in the ground, so the excavation work is carried out with the driver's sense, and the driver performs the excavation work. When the impact on the pipeline is detected, the excavation work is carried out with the bucket moving so that the bucket does not touch the underground cable.

However, when the driver performs the excavation work without knowing the location of the underground cable, the trauma of the excavator's bucket destroys underground pipelines such as electricity, communication cables and gas and water.

In addition, damage to underground pipes such as electricity, communication cables and gas, water supply due to excavation work may lead to large safety accidents such as electric shock, communication failure, gas explosion, single stage.

On the other hand, in order to prevent such safety accidents in advance in the sand buried in a certain thickness on the upper part of the pipeline to be installed, the cable protection sheet made of plastic or cable protection plate made of plastic on it, and backfilled to the ground Construction is being done.

However, the above protection method can be seen that when the excavation to detect underground buried by manpower, the protective sheet or the plate is found and the cable is buried, but does not function when using equipment such as excavators Failure to do so, safety accidents due to breakage of underground pipelines such as electricity, communication cables and gas, waterworks, and the like are frequent.

The present invention has been made to solve the above problems, it is provided with a multi-protector made of reinforced concrete block structure with reinforcement in the reinforcement inside, it is constant in the upper part of underground pipelines such as electric, communication cable and gas, waterworks Constructed to be connected along the pipeline by spaced intervals, it is possible to easily detect the buried state of the underground pipeline, and the multi-protector has a high strength to minimize the damage to the underground pipeline by minimizing damage even if the bucket touches during excavation work When the impact is applied to the multi-protector from the outside during the operation, the capsule that emits pigments and odors explodes so that the excavator operator can easily and reliably identify the underground area of underground pipelines such as electricity, communication cable, gas and water supply during the excavation work. Multi-protector can be easily connected regardless of the number of underground pipes Using it with a functional underground pipeline makes it possible to further improve the efficiency and it is possible that multi-protect the object of the present invention to provide a construction method of underground pipelines.
