31 large tonnage rollers ensure the construction of two estuarine hydropower stations
In November 1st, the two river estuary hydropower station in Yajiang County of Sichuan started filling the core wall of the dam. This marks the start of the main project of the hydropower station with a total installed capacity of 3 million kilowatts. The 7 31 large tonnage rollers participated in the rolling of the core wall of the dam.
In the world's most complex and highest elevation earth and stone dam hydropower project, the 31 roller has been recognized by the customers with stable quality and perfect service.
Uninterrupted operation for 24 hours test the quality of the equipment
The power station is located in the Yalong River and slobber fresh water river confluence downstream 2 km, nearly 3000 meters above sea level, harsh climate, steep mountains, to cut off the surging of Yalong River hydropower dam, a 295 metre high building in the canyon, construction difficulty is second to none in the world.
The construction materials of the rockfill dam for the two river estuary hydropower station are all taken from the local area. The total amount of the total filling of the 43 million sides of the whole dam is equivalent to the volume of the 6 "bird's nest" stadium in Beijing. During the construction of the dam, the 31 26 ton road roller is responsible for the rolling of the clay layer of the heart wall, and the 33 ton roller is responsible for the compaction of the rock layer. As the construction area is large and the construction time is tight, the road roller must work 24 hours without interruption. Li Jian, the 31 marketing representative responsible for the two estuarine project, told the author: "the two shifts of the construction staff are down, but the equipment is only in this class, and there is basically no time to shut down. These compactors need to work for about 4000 hours a year, which is more than two times the amount of other projects, which puts forward high requirements for the quality and stability of the equipment.
The main power plant project construction unit slobber twelve water in the water and in the five years and 31 have worked closely in Changheba Hydropower Station project just completed, high reliability and high efficiency showed 31 road so they are very satisfied, so the work of Dam RCC more arduous task of Mesopotamia slobber power plant project to the 31 Road machine. Since its start up, the 31 roller has ensured the overall progress of the construction under the condition of high altitude, high intensity and continuous operation.
Service personnel stationed in deep mountains and "nanny" at any time
Due to the remote engineering area, in order to ensure timely processing of equipment problems, 31 dispatched a service engineer to the site, and shared the same with the project construction personnel.
The 31 service engineer, who had been living in the mountains for more than a month, was named Ren Youheng, "the plateau was more serious when he arrived." Ren Youheng told the author, "the altitude is close to 3000 meters, and there is no such experience before. So I always feel dizzy, dry mouth and uncomfortable all day." In addition to the plateau reaction, the huge temperature difference between the day and night on the mountain is also difficult to adapt, the temperature of the night has reached zero. It is said that it will snow for two days. However, for any constant, these can be overcome, when I asked him where the place is what, he said only four words: "a little lonely."
In order to finish the work of 31 equipments in the two estuarine project, the twenty year old boy is fighting against the harsh natural environment and hard living conditions with a positive and optimistic attitude. At present, as the constant has been completed on the site of all 31 rollers of the first security work for small machines appear, he is also the first time processing is completed, to ensure the normal operation of equipment.
China build two electricity power station 125 estuary consortium equipment department leadership on the stability of 31 roller and high reliability and affirmed such evaluation 31 services: "for those of us in remote areas of engineering equipment, customer service service is especially important, such as 31, sent a permanent site to provide services like whenever and wherever possible. A letter to us, the product with peace of mind."
