Description

Process of working road lighting with several earth connection}

In the case of installing various street lamps, the street lamps must be grounded according to the prescribed regulations in order to prevent various electrical safety accidents caused by the contraction of the facilities installed in the street lamps. This is an institutional device that is inevitably provided to prevent such an electrical safety accident, because if the equipment or facilities are charged while the contraction comes in contact with the charging part leads to an unexpected big accident.

Conventional street lamp foundation installation method consisting of anchor bolts for fixing street lamps, supply wires, discharge wires and concrete blocks, installs a street lamp wire manhole on one side of the street lamp foundation, and only the wires connected to one side inside the manhole Since the winding is formed, if the wire is pulled by a fork-lane, etc., only one wire is released, so there is a high possibility that the wire is broken, and even if it is not broken, there is a high possibility that the coating may be peeled off. Since there should be a problem such as occupying a large area on the road.

The conventional street lamp foundation installation method consisting of anchor bolts for fixing street lamps, supply wires, discharge wires, and concrete blocks is carried out by constructing concrete blocks to fix street lamps, and then connecting ground wires to the outside of concrete blocks. There is a problem in that the ground is installed, and each individual ground has to be grounded separately after the concrete block construction. In addition, in the conventional street lamp foundation installation method, the individual ground line is protruded to the outside of the concrete block, so that the individual ground line is cut or damaged by fork lanes during other constructions such as city gas pipeline construction, water and sewage construction, underground cable construction, and landscaping construction. there was.

The present invention is to solve the problems of the prior art as described above, after performing a concrete block construction consisting of an anchor bolt, a supply wire, a discharge wire and a concrete block for fixing the street lamp, ground wire to the outside of the concrete block separately It is possible to easily carry out the integrated street light foundation that connects the connection ground line and the fixed ground line at the same time without the need for the individual grounding work to install the individual ground by connecting them. Since the individual ground line does not protrude to the outside of the concrete block, It is possible to solve the problem that individual ground wire is cut or damaged by fork lane during other construction such as construction, water and sewage work, underground cable work, landscaping work, etc. to provide. In another aspect, the present invention provides a street lamp base anchor bolt of the street lamp base integrally formed from the top to the bottom of the street lamp base, to place the ground copper plate in the lower portion of the street lamp base and to connect the bolt and the copper plate.

The present invention is connected to the lower part of the conduit through which the supply wire and supply connection ground wire passes, the conduit pipe through which the discharge wire and the discharge connection ground wire pass together, the fixed ground pipe through which the fixed ground wire passes, and fixed ground, The fixed ground copper plate installed on the lower surface of the block, the ground connection copper plate which is installed on the upper part of the concrete block, the ground connection copper plate connected to the supply connection ground line, the discharge connection ground line and the fixed ground line, and the concrete block. It is about installation method.

The present invention in the street lamp foundation installation method consisting of anchor bolts for fixing the street lamps, supply wires, discharge wires and concrete blocks after the concrete block construction can be fixed to the street lamps to open the ground wire to the outside of the concrete block separately As a result, it is possible to easily carry out the integrated streetlight foundation that connects the connection ground line and the fixed ground line at the same time without the need for the individual grounding work to install the individual ground, and because the individual ground line does not protrude outside the concrete block, During the construction, water and sewage works, underground cable work, landscaping work, etc., it is possible to solve the problem that the individual ground line is cut or damaged by fork-lane, etc., and it is effective in preventing power failure or short circuit. In addition, the present invention is composed of an anchor bolt of the street lamp base integrally from the top to the bottom of the street lamp base, and the fixed ground copper plate is placed on the lower part of the street lamp base, and the ground resistance exceeds the standard value, except in special cases. There is no effect of grounding work.
