Timely resolution of street lamp failures can not only maintain urban infrastructure and city appearance, but also facilitate residents' lives and beautify the city. It can also establish a good investment environment for the city and promote the continuous development of two civilizations. Based on the reality of Daqing, this paper discusses the current situation, causes and countermeasures of street lamp failure, in order to better solve the problem of street lamp failure. First, the status quo of street lamp failure Daqing City streetlight was built in 1979, from the beginning of 108 ç› to the current 6045 ç›, is located in the Zhongqi Road, and other 68 main roads. Since 1979, due to the lack of specialized agencies and personnel management, most of the street lights failed to be repaired in time. This situation changed after the municipal government established the Public Utilities Administration in 1996. The Public Utilities Administration has a street lamp management office and has set up a professional team to repair and manage the street lamps. Judging from the maintenance and management situation in recent years, Daqing City Road has experienced frequent failures. Taking 1998 as an example, there were 2,235 street lamp failures in the whole year, with an average of 186 per month. There are two types of common faults: one is high-resistance fault and the other is low-resistance fault. The so-called high-resistance fault, that is, the cable is blown, the meter measures the resistance, or the insulation decreases between the phases or the ground, but there is a certain resistance; the so-called low-resistance fault, that is, the wire is short-circuited or completely shorted to the ground, the current Increase, the power transmission has a trip phenomenon. These two types of faults and their frequent occurrence pose a threat to the normal use of street lights. Therefore, we must pay full attention to the reasons and countermeasures. Second, the main cause of street lamp failure 1. Poor construction quality due to the quality of the construction caused by failures. Main performances: First, the depth of the cable trench is not enough, the sand-covered bricks are not constructed according to the standard; the second is that the production and installation of the aisle tubes do not meet the requirements, the two ends are not made according to the standard; the third is when paving the cable The fourth pre-buried pipe is not constructed according to the standard requirements, mainly because the pre-buried pipe is too thin, plus a certain degree of camber, it is quite difficult to wear the cable, and there is a "dead bend" at the bottom of the foundation; The wire nose crimping and insulation wrap are not thick enough, and after a long period of operation, the phases are short-circuited. 2, the material is not only from the failure situation handled in recent years, the material quality is also low. The main performance is: the wire contains less aluminum, the wire is relatively hard, and the insulation layer is more common in recent years. 3. The quality of supporting projects is not too hard. Street light cables are usually laid on the sidewalk. The construction quality of the sidewalk is poor, the ground sinks, and the cable is deformed by force, resulting in cable armoring. In particular, the northeastern region is in an extremely cold zone, and the arrival of winter makes the cable and soil form a whole. Once the ground subsides, it will be strained at the bottom of the streetlight base, and when the rainwater is too much in summer, it will be blown at the base root. 4, the design is unreasonable on the one hand is overloaded operation. With the continuous development of urban construction, street lamps are also constantly expanding. When new street lamps are often close to which streetlights, which circuit is received, and in recent years, the advertising industry has developed rapidly, and the load of advertising is also connected to the street lamps. The load of the street lamp is too large, the cable is overheated, the wire nose is overheated, the insulation is lowered, and the grounding short circuit occurs. On the other hand, the lamp post is designed only considering the condition of the lamp post, ignoring the space of the cable head, and the cable head is wrapped. In the future, most of the doors will not be closed, sometimes the cable length is not enough, the joint production does not meet the requirements, which is also the cause of the failure. Third, to solve the problem of street lamp failure Whether it is to solve the current problem, or in the long run, the main idea to solve the street lamp failure is to implement the "four." 1. The integration of the industry is to consider design, construction and management as one person. This is conducive to centralized research. After cooperative development, testing and acceptance, there are currently 25 control points, but there are 266 existing cities. Compared with the control points, the ratio is quite perfect and the scope of the “three remotes†is expanded. There is still a lot of work to be done. 2. Make full use of scientific and technological means and do a good job in management. Develop statistical software, use computer to carry out scientific statistical calculations, timely grasp the changes of street lighting facilities, and carry out accurate and complete statistical records. A special person will conduct a general survey of street lighting facilities in the city every two or three years. Gradually adopt CAD technology to fully update the street light circuit diagram. Establish a database of various facilities for street lamps and update them in time according to project construction and facility maintenance. In the road lighting calculation, three-dimensional lighting type map and even the scene lighting renderings, computer-based development attempts, gradually expand and improve the scope of application, and gradually realize the computerization of engineering technology management. Fourth, strengthen maintenance management, ensure the normal operation of the facility 1. Strengthen the training of maintenance personnel. On the one hand, urban street lights are closely related to the life of the citizens. Its operation directly affects the image of the party and the government. It is necessary to improve the maintenance of street lamps by maintenance personnel. Awareness and a sense of responsibility. On the other hand, with the acceleration of the development of urban street lighting technology, the extensive use of new technologies requires maintenance personnel to continuously update the maintenance expertise to meet the needs of the work. 2. Accelerate the expansion of maintenance equipment, increase the number of street lamps and the increase of service areas, so that the workload of maintenance personnel will increase greatly. Without increasing personnel, it is necessary to continuously improve and update maintenance equipment to improve work efficiency. 3. Implementing the maintenance target responsibility system On the basis of delineating the street lamp management area, implement the maintenance responsibility system at all levels to implement the fixed person, fixed post, and responsibilities. It is necessary to conduct regular inspections, regular maintenance, and find out who is responsible for problems. . 4. Strengthening the investigation and punishment of law enforcement On the one hand, speeding up the formulation of normative documents on street lamp management and creating conditions for legal management; on the other hand, the joint urban management department will increase the enforcement of street lamps, seriously investigate and punish the destruction of street lighting facilities, and ensure the normal operation of street lighting facilities. .
