Years repeated construction of underground pipe network in Zhengzhou， water pipes dug breaks a year 355 times

France great writer Victor Hugo once wrote: "the sewer is a city of wisdom and conscience. "All along, the underground pipe network is a city in the throes of chaos, crumbling, man city, rain water, dug trenches, power outages, traffic jams, and many other" urban disease "were brought on by this unseen underground network. How to ensure the urban underground "lifeline" safe? Now, a "revolution in underground pipe network" are afoot in Zhengzhou, we would like to record this process with a pen, and one of the issues discussed.

"The Zhengzhou ditching every day a day do not dig called Zhengzhou", more than 10 years ago, Zhengzhou, imitated in the language of that spread widely among the public. After more than 10 years, this situation has not been fundamentally changed, not greater. So, this is why the persistence? Which direction to the management of underground pipelines?

　　"Queer" various departments repeated broken road

"Longhai road viaduct engineering, road on both sides basically every day are in dug ditch, fill good has dug, dug good has fill, then again dug......" July 2, lived Zhengzhou Longhai road railway homes community of Liu Mr said, early in Zhengzhou Longhai road viaduct engineering began zhiqian, some pipeline sector on began dug ditch, with with the engineering of full starts, road sides of dug ditch phenomenon on no stops had, and let people incredible of is, dug ditch of is not a sector, but multiple pipeline sector, as rain sewage, and tap water, and gas, and heating ……

It is understood that these trench Department are to cooperate with municipal construction, belongs to the underground pipeline for migration. "With so many line departments, after digging in this sector to fill, then dug another Division, which I do not quite understand, wouldn't it unified? "Mr Liu was very puzzled.

It is reported that every major public works project headquarters, various line departments is based on the engineering command of the unified command, entering in turn moved to owning pipelines.

　　"Reality" over more than 20 kinds of pipelines "self-built self-tube"

Now, in Zhengzhou, the capital of the three-ring, as long as you take to the streets, it is easy to see roadside construction scene.

"Road not repaired when that seemed to have the whole thing. And roads repaired, it has continued with other municipal departments to dig trenches. A dozen years ago, people said, ' dig trenches every day Zhengzhou day do not dig in Zhengzhou. Now, after so many years, I did not see anything change. ”

In the interview, there are people who think, "every day ditch Digger" description of Zhengzhou municipal construction management, lack of unified scheduling and planning departments on their own.

Reportedly, the Zhengzhou underground pipeline systems are very complex, a total of eight categories and more than 20 kinds of pipelines, involves more than more than 30 functions and property sector. In other words, the current underground pipes and lines, in a fragmented state, build their own management and diversified pipeline crossing, lack of transparency, frequent digging a ditch at the same time, also suffered a security incident.

　　"Helpless" water lines being dug 355 times a year

In the interview, Zhengzhou tap water, electricity, heat, gas, heating, sewage and rainwater and even communications, the head of the fiber Department said, so many lines and there is no central governing body, therefore, major works are separate construction, and they are not willing to do the "time and effort also get criticized by the public" gives way to diversion projects.

"In fact, we ourselves are victims. "The tap water in Zhengzhou said Li Ji, Deputy Director of investment holdings limited network, apart from the municipal building apart from the necessary diversion, water pipe dug off road accidents but also is quite amazing. In 2010, there were 355 cases, on average, almost every day. 2011 114, 2012, 68.

The serious accident of pipeline was cut off, heat, gas, electricity and other sectors also occur frequently. Accidents, they rushed to the scene of pavement, repair.

　　"Analysis" underground pipes that lack of transparency is the main

According to the Zhengzhou city water management Ordinance provides that construction company construction of city public water supply facilities damaged, ought to inform public urban water supply Enterprise repair, repair costs and the losses borne by the employer. In fact, many accidents occurred, the contractor did not immediately inform, there are some construction units then fled the scene.

In accordance with the relevant provisions of the Ordinance, may involve water pipeline construction in construction, should inform water company. But most of the time, the construction unit does not notify the water company, water companies informed of patrolman information relying mainly on its own.

"A few days ago, we held in the area by opening a natural gas pipe was accidentally dug off combat exercises, is the position that was cut off in response to the natural gas pipeline. "The Zhengzhou China resources gas company pipeline network experts Du Keli said, they have four lines, each pipeline has a special inspection team if found in other sectors of construction, it will promptly inform us of construction of underground pipelines, to remind the contractor, but these reminders sometimes does not prevent accidents from happening.

Reasons for the pipeline was cut off, said the head of sectors such as water, electric heating, in addition to accidentally outside many construction on underground pipeline components do not know much about, as a result, large mechanical horse, the pipeline was cut off. And when they repair, nor understand what underground pipelines, and also separately to multiple pipelines called asking pipeline.

In the interview, head of multiple pipelines, said as far back as two years ago, they will meet in Zhengzhou to map underground pipelines 3D maps, if it draws a better picture for their construction and repair will go a long way in the future.

　　In recent years the frequency of Zhengzhou "ditch Digger"

On June 27, a pulling flour truck drives through Zhengzhou new Street, the road suddenly collapsed, appears about 2 square pit.

Municipal authorities find the road collapse causes found that, due to a nearby construction site under the power tube, resulting in ruptured underground sewage pipes, sewage seeped into the pipeline, but scour the Earth to form voids, coupled with heavy rolling road subsidence occurred.

In fact, in recent years there have been numerous pavement in Zhengzhou collapsed. In April 2013, the southwest corner of the intersection of Longhai road and station Street, the slow lane and fast lane in the middle of a road collapsed, forming a crater of about 8 square meters.

In January 2014, Longhai road and Kunlun mountain road intersection near the hollowed out of pavement subgrade, pavement formed under the giant pit, large enough to hold a bus.

Oriental Press comb this report found that road subsidence, flood, burst pipes, gas leaking after an event, given by relevant departments investigate the causes associated with the underground pipeline. Orient today newspaper Chief Zhao Dan
