Construction machinery in the nuclear crisis in Fukushima, Japan

On March 11, 2011, a 9-magnitude earthquake struck Japan, triggering a tsunami and nuclear leak crisis. Empathy is the common emotion of human beings. The nuclear leakage crisis triggered by this earthquake affects the nerves of the world. In order to cool the heavily damaged Fukushima Nuclear Power Plant reactor, the Japanese authorities used helicopters and fire engines to try to inject seawater into the nuclear power plant, and had successfully restarted the electric water pump of the reactor, but these measures did not prevent nuclear leakage.

In front of the disaster, there are no borders, and even more so in the face of the nuclear crisis. When the nuclear leakage occurred at the Fukushima Daiichi nuclear power plant, the Japanese authorities tried their best to use various advanced equipment to cool the nuclear power plant. Because fire fighting vehicles and military helicopters have low injection rates, they used the experience of the former Soviet nuclear power station for disaster relief and considered using pump trucks to participate in disaster relief. At this time, finding the most reliable pump trucks in the world with long booms has become their most pressing problem.

The Sany 62m pump truck was the Sany Heavy Industry crew of the No. 1 unit of the Fukushima nuclear power plant as the world's longest jib truck record holder, and soon entered the vision of Tokyo Electric Power Company. After careful calculations, Tokyo Electric Power Company proposed to Sany Heavy Industry to purchase a 62-meter pump truck model SY5502THB to inject water into the reactor for cooling. After understanding the situation, Sany Heavy Industry stated in a humanitarian spirit that it can donate the required pump trucks through the Red Cross Society of China and Japan and is willing to provide all-round support. Tokyo Electric Power Co., Ltd. was very grateful to Sany Heavy Industry for this move, and then officially issued a related document to Sany Heavy Industry to confirm the acceptance.

According to reports, according to the specific operating conditions of the Fukushima nuclear power plant, the crew installed a small-diameter water spray pipe at the end of the pump boom in the simulated water-flooding test, thereby increasing the length of the pump arm to 67 meters and increasing the number of nozzles. Pressure and spray distance. A 360-degree camera is also mounted on the pump truck. When the pump truck is in operation, the condition of the fuel tank can be seen at any time. More importantly, a temperature measuring instrument is also installed on the pump truck. The staff can measure the nuclear radiation concentration at any time.

It is worth mentioning that in order to minimize the damage caused by nuclear radiation to the operators, Sany Heavy Industry engineers have developed a remote wireless remote control technology based on profound intelligent technology and unique advantages, and realized the pump truck is 2 kilometers away. Unmanned operation. At present, this technology is unique in the world.

It is understood that the three operators who risked their lives and shouldered the Jedi emergency mission are the front line staff of the first nuclear power plant of Tokyo Electric Power Company. The youngest of the three was Masao Sakai, 43, who is the director of the civil engineering department of the Fukushima Daiichi nuclear power plant of Tokyo Electric Power Co., whose home is in Fukushima. Another operator is Takehiko Yamato, 47, who worked there since the construction of the Fukushima Daiichi nuclear power plant. After the earthquake, he personally experienced two previous explosions of the nuclear power unit. During the training and testing, they were very amazed by the long, powerful, efficient, and safe operation performance of Sany Pumps. They all expressed that with the help of Sany's high-quality products and services, they are confident to complete this. Tasks.

In this way, at 12:45 on March 27, after a total of 8 days of preliminary work, including equipment commissioning, land and sea transportation, operator training, and water testing, the 62-meter pump truck finally arrived at the Fukushima Nuclear Power Plant Command Center.

At 12 o'clock on the March 31, the pump truck officially began cooling water for Unit 1 of the Fukushima Nuclear Power Station. According to the latest news, the equipment is running normally and the water injection effect is very good. According to professional sources, although the six units of the Fukushima nuclear power plant have announced that they are all scrapped, the water injection and cooling are the only steps that must be finalized. According to Japanese official sources, the core temperature of Unit 1 reactor is still as high as 2,500 degrees Celsius, so water injection is required. The cooling work may continue for about a month.

The Putzmeister Pumping Vehicle is the only one construction machinery manufacturer involved in the nuclear spill rescue for the flooding of Unit 4 at the Fukushima Nuclear Power Station. According to the Putzmeister official website in Germany, Putzmeister concrete pump trucks have also participated in the rescue work in Fukushima. At the same time, Bekerde, an engineering giant from the United States, also dispatched remote control water jets to Japan.

The leakage of the Fukushima nuclear power plant caused by the tsunami in Japan shocked the world and attracted wide attention from various countries. Ask for quick rescue operations. After the accident at the Fukushima nuclear power plant, Tokyo Electric Power Co., Ltd. sought help from Putzmeister, and immediately purchased a Putzmeister Putzmeister M58 pump truck for on-site water cooling and emergency rescue; Putzmeister's 58-meter pump truck set off at a rapid pace and arrived in Japan on March 21, 2011, through the green channel of the Japanese Customs for Relief Substances, and immediately put on-site emergency rescue work.

The 58-meter vertical M58-5 pump truck with 5-arm cooling of the damaged cooling hood of the Fukushima nuclear reactor has the advantage of being capable of pouring cooling water from a long distance above a damaged building.
