Huangdao area immediately organized in the sea layout two booms. The disposal process, morning at ten thirty PM, coastal river road Huangdao district and Zhaitang Island Road Interchange deflagration, at the same time in the mouth is deflagration occurred oil pollution on the sea. A preliminary analysis is pipeline oil into the municipal pipe network cause deflagration occurred, the tipping point and detonated the cause is under investigation, accident removing failure reason of terror.
By November 26, 2013 11, Qingdao economic and Technological Development Zone (Huangdao District) pipeline leak explosion has killed 55 people, injured, 9 missing, 166 people.
The afternoon of November 24, 2013, general secretary of the CPC Central Committee, President, chairman of the Central Military Commission Xi Jinping made important instructions, requirements of Shandong province and related aspects of organizational strength, remove dangers, make every attempt to rescue the missing, injured, and to identify the cause of the accident, the accident lesson summary, implementation of safe production responsibility, strengthen production safety measures, and resolutely put an end to this kind of accident.
On the morning of 25, the Shandong province Qingdao city "11 · 22" Sinopec Dong Huang oil pipeline leakage and explosion special major accident investigation group plenary meeting held in Qingdao. Survey group group leader, director of the State Administration of work safety Yang Dongliang pointed out, the accident losses, the prominent problem exposed, oil pipeline and the city drainage pipe network layout is not reasonable; not to implement the safety production responsibility, the pipeline of lax management, result in oil leakage; emergency disposal after the leakage is improper, not to set up warning area closed road, notify the evacuation of personnel, and other preventive measures according to the regulations. This is a very serious liability accident.
25 evening, the police have control of 11 · 22 Dong Huang oil pipeline leakage and explosion accidents in Sinopec relevant personnel 7 people, staff of Qingdao economic and Technological Development Zone 2.
At present, some details of news reports the exposed, it is difficult to eliminate the pipeline safety concerns for. Why can easily spill into the municipal pipe network, pipeline distance municipal pipeline why so recent, relevant design defects or not?
How to establish a set of "oil pipeline safety" accident processing security measures is very important, such as "oil pipeline safety" this high-risk facilities unexpected deflagration accident, what what measures should be taken in isolation, early warning, should have a set of scientific and technical process and specification. To prevent accidents, should avoid liability, let the responsibility parties truly supervision in place, management in place, security in place and accountability in place.

Underground pipeline explosion event query
China city underground pipe network after years of development, the formation of the network system of the perplexing, security can not be ignored, the accident constantly, in the online search a simple typical accident of the underground pipe network.
June 27, 1985 at eleven twenty in the morning, a loud bang, Yuzhong District, Chongqing City, Da Xi Gou Luo Jia Yuan area sewer suddenly explosion. Strong explosive force to blow up sewer 271 meters, 81 residents of the housing and a few stores suddenly come to nothing, 26 people were killed, 91 injured, local area power outages, expire, serious losses.
In 1992, in the heart of Chongqing, the most concentrated stream of Yuzhong District, has been the worst of the septic tank explosion accidents, resulting in 25 deaths, 91 people were injured.
Early in the morning of June 29, 2004, Jiangjin of Chongqing City, west of Binjiang Road underground sewage pipe explosion, more than 100 meters of the pavement was bombed to smithereens, a man full of severe burn. While a year ago, is also in the Jiangjin Binjiang Road, also occurred in the underground pipeline explosion. The explosion may have been a sewage pipe network with large quantities of flammable gas trigger.

In December 27, 2010, Yibin City South Gate Bridge underground natural gas pipeline explosion, resulting in 1 people were killed and 3 others injured.
January 23, 2013 14 am, Guangxi Beihai area, the underground pipeline explosion accident occurred, about one hundred meters of road is destroyed. It is understood, no casualties were reported, the local government has dispatched personnel investigation, the cause of the accident is still unknown.
A silicate Factory in late March 19, 2013 Jiangxi Nanchang city gate, underground pipelines and liquefied petroleum gas explosion, the road was destroyed nearly one hundred meters, the road several hundred meters of the manhole cover is blown, many vehicles move.
Dangerous city underground pipe network is where the monster?
The lesson of blood so that we have to calm down, a common understanding of the city underground pipe network and its challenges and solutions.
1 city underground pipe network
City underground pipeline is in the city planning area, buried water supply in city planning road, drainage, gas, heating, industrial and other pipelines, electric power, telecommunication cable and pipe underground pipe ditch (gallery) etc..
From the nature of the pipeline transport or discharge material to points, can be divided into the city underground pipeline water supply, drainage, gas, heat, electricity, telecommunications, industrial and integrated trench (gallery) eight lines, each kind of pipeline can also according to the differences in transmission or emissions or its functional difference is divided into small different types of.
As to the water lines can be divided into living water, circulating water, fire water, green water and water etc.;
Gas pipeline can be divided into gas, natural gas, liquefied gas and coal seam gas drainage pipeline; can be divided into rainwater, sewage and confluence; heat pipe can be divided into hot water, steam and hot springs;
Power lines can be divided into power supply, lighting, trams, signal, advertising and special DC line etc.;
Telecom pipeline can be divided into the local, long-distance, broadcasting, cable television, broadband, monitoring and special;
Industrial pipeline can be divided into hydrogen, oxygen, acetylene, petroleum, aviation, slag and waste; integrated trench (gallery) pipeline can be divided into comprehensive pipe gallery and integrated pipe ditch.
2 main problems in the construction of city underground pipeline
The construction and management of underground pipeline;
Underground pipeline data discrete storage, diverse formats, poor accuracy, use of difficulties;
Underground pipeline information resource property department, low level of information sharing;
Renewal of the underground pipeline information dynamic low, the lack of long-term mechanism to ensure.
Due to the long history and accumulated continuously crossing pipeline, and the lack of modern management platform, management information not perfect etc. these reasons, is the main reason behind the accident again and again.
3 underground pipe network security solutions
Because a lot of accidents, harm of governments around the world to the city underground pipe network also has certain understanding, but this kind of understanding only stay in the level of consciousness, the lack of action, the lack of real investment, most of the underground pipe network without the hazardous gas monitoring instruments and equipment installation, and there are still risks. Therefore, the need to find an effective application of management measures as soon as possible, reduce and avoid the occurrence of accidents.
By means of information technology, the government of unified planning, unified management of underground pipelines, underground pipe network in the city management monitoring system, the establishment of modern information management system and the underground pipeline data system. It may form an orderly underground order, can be effective to avoid such accidents.
