Tianjin Millennium Landscape Light was "drawing radish"

Recently, the Haihe belt park in the section of Haijin Bridge to Fenghua Bridge was ruined by black hands, and thousands of landscape lights were “drawered”. During the festival, the Haihe Strip Park, which was supposed to be lit up, was dark. After the landscape lights were stolen, the exposed wires and the left pits caused a lot of safety hazards to the Tianjin residents who came for the walk. However, these lost landscape lights cannot be replenished in the near future. The reporter learned that the landscape facilities such as floor lamps, seats and garbage bins along the Haihe River were all managed by the construction unit Chengtou Group Haihe Company before the handover, and the company had to set up a few times each year to maintain and replenish these facilities. million dollar. The lost landscape lights are expensive, and now the company has no money to fill the hole.

Residents around the world: How many days have you lost a thousand miles?


Ms. Qiu, a citizen of Tianjin, lives near Zhengzhuangzi in Hedong District and often bends to the Haihe River. Yesterday (February 20), she slipped from the Guotai Bridge to the Haijin Bridge along the east bank of the Haihe River and found hundreds of landscapes in the Haihe Ribbon Park. The floor lamp was almost gone, and it was determined from the remaining lamp slot holes and the wires that were exposed barely. This could never have been removed by the maintenance worker, but was stolen. "When I went for a walk along the Haihe River, I found that there were sporadic lights disappeared. I didn't come over the past few days in the New Year. I didn't think that the landscape lights of the Haihe River were almost lost." Master Zhang also said that the second month of the twelfth lunar month On the seventeenth day, he came to the Haihe River to fish, but only the scattered ground lights were lost. There was no such large-scale "missing".


The reporter found that not only the landscape lights on the east bank of the Haihe River were seriously lost, but also the loss of the ground lights on the west bank of the Haihe River was serious in the same landscape belt. From the Haijin Bridge to the Fenghua Bridge, the landscape lights that have been lost on both sides of the east and west have passed thousands of miles, and large and small holes on the ground can be seen everywhere. Not far from Fumin Bridge, there is a set of high-voltage and low-voltage power control boxes powered by street lamps on one downhill slope at the corner of the wall. There are three control boxes in total, one of the central locking holes is broken by hard objects, and the door is opened. Inside, there are rows of power control switches. Mr. Zhao, who walked on the side, guessed: "I have lost hundreds of lamps. This is definitely a gang. The power control box must also be ruined by the group, so that it is convenient to cut the wires when stealing lights."


Haihe Company: Millions of holes in one year can't afford it!


The staff of Haihe Company, a city investment group responsible for the construction of the Haihe embankment, said that the lighting facilities were part of the company's construction project. As a construction unit, the damage of the Hainan River to the Guotai Bridge section of the Haihe River embankment was known years ago. Unexpectedly, the situation in a few days has become so serious. According to reports, some facilities such as floor lamps, seats, and garbage bins along the Haihe River have been subjected to vandalism and theft to varying degrees. The lost lights are costly and will be lost every time they are refilled. How to protect these utilities is really a headache for the construction unit. Nowadays, in order to maintain and replenish the public facilities of the Haihe River landscape belt, the construction unit has to build millions or even tens of millions of yuan each year, which is outside the construction budget for the construction unit. Today, they don't have the money to replenish and repair the lost lighting. The staff said that after the completion of the construction, the relevant facilities of the relevant Haihe embankment have been handed over to the relevant departments for special management and maintenance. Only after the responsibility of the people will be in place for daily supervision and maintenance, can the losses be reduced as much as possible. However, in the previous handover, the handover of the lighting facilities alone has not been implemented smoothly because of the departments involved in electricity. Recently, they will actively contact the relevant departments, strive to complete the handover as soon as possible, achieve special management, and avoid the recurrence of such large-scale lights theft.
