Description
Technical Field
The invention relates to the technical field of urban road construction, in particular to a street lamp cable anti-theft structure.
Background
With the strong promotion of urban construction by China, urban roads in China are more and more, and people travel more and more conveniently. The street lamps at two sides of the road need power supply lines to supply power, and the cables of the power supply lines are arranged in the cable tubes in a penetrating mode and buried underground. On the sidewalk at both sides of the road, inspection wells are arranged at intervals along the trend of the cable, and the distance between every two adjacent inspection wells is 25-30 meters.
The cable passes through the manhole, and the cable pipe extends into the manhole and opens into the manhole. When constructing the cable duct, the common practice is to construct two cable ducts simultaneously, and two cable ducts are arranged in parallel at intervals on the same horizontal plane, one cable duct is used as a working duct, a power supply line of a street lamp and the like are arranged in the working duct in a penetrating manner, and the other cable duct is used as a standby duct, so that cables can be arranged in a penetrating manner according to needs when roadside equipment increases in the future.
When line faults occur and the line needs to be overhauled, a worker can conveniently go into the inspection well to conduct investigation and overhauling work on the cable line. The inspection shaft has the advantages that on one hand, the inspection shaft is convenient for line inspection and overhaul, and on the other hand, a multiplicable machine is provided for a thief. After the thief prizes the well cover of the inspection well, the cable can be conveniently pulled out from the cable pipe to be stolen, so that public property is jeopardized, road illumination is prevented, inconvenience is brought to night traffic, and accident rate is increased.
When the inventor solves the problems, firstly, the technical scheme of the experiment is that soil layers above the cable pipes are excavated beside the inspection wells, the cable pipes are broken, and a certain length of anti-theft concrete is poured into the cable pipes, so that lawless persons cannot completely draw out lines in the cable pipes between the two inspection wells, and only a short section of cable from the inspection wells to the pouring position can be stolen. This solution, however, presents a number of problems: 1. the construction is inconvenient, needs to excavate the soil layer, if the cable pipe is equipped with protection concrete outward, still need break protection concrete. 2. The maintenance is troublesome after being stolen. After being stolen, the cable is disconnected at the pouring position, the pouring position is required to be excavated again, the poured anti-theft concrete is broken, the cable can be stripped for wiring operation, the protection effect of the anti-theft concrete is easily damaged during breaking, and the anti-theft concrete is required to be poured again after wiring. In a word, the scheme is troublesome to construct and maintain, low in efficiency, high in material consumption and high in cost.

Development and description:
because the cable tube opening is at the inspection well, when pouring anti-theft measures are taken in the inspection well, if the pouring height is lower than the cable tube, the anti-theft effect cannot be achieved, and lawless persons can pull out and steal the line (between two inspection wells) in the cable tube outside the cable tube opening. If the casting height is higher than the cable tube, the working cable tube 2 and the standby cable tube 3 are identical in height as specified in the existing construction manual, so that the working tube and the standby tube are plugged at the same time, and the standby tube is difficult to start in the future. This is also what the inventors of the present application have first conceived, not the technical solution of the present application, but the solution in the background art.
The inventor does not adopt the current general cable construction method, through the staggered arrangement of the opening of the working cable duct 2 and the opening of the spare cable duct 3 in the inspection shaft, provides the basis for pouring the anti-theft concrete in the inspection shaft, and the poured anti-theft concrete can not cause the manufacturing obstacle for the subsequent starting of the spare cable duct 3. Even if an illegal person prizes the well cover of the inspection well and enters the inspection well, only a small part of the cable above the antitheft concrete can be stolen, so that the cable main body in the cable pipe is protected. After the working cable 7 in the inspection well is stolen, a maintainer only needs to break the anti-theft concrete, and draw out the redundant part of the working cable 7 (each working cable tube 2 has a redundant length of 0.5+/-0.1 meter) from the working cable tubes 2 at the two sides of the inspection well, so that the cables in the working cable tubes 2 at the two sides of the inspection well can be conveniently connected together without additionally transporting and accessing new cables, and the cable tubes still have enough length in the inspection well to facilitate maintenance and overhaul work.
The above embodiments are only for illustrating the technical solution of the present invention, and it should be understood by those skilled in the art that although the present invention has been described in detail with reference to the above embodiments: modifications and equivalents may be made thereto without departing from the spirit and scope of the invention, which is intended to be encompassed by the claims.
