Huashang.com - Huashang Daily News The 110-meter-high powerhouse of the Weinan Thermal Power Plant (formerly Duqiao Thermal Power Plant, hereinafter referred to as the Weinan Thermal Power Plant) was once the landmark of the industrial development in the southern part of the city, and it also sent warmth to the people of southern Anhui in the cold winter. . On May 24, the 110-meter-high chimney of the Weinan Thermal Power Plant, which has been in operation for 29 years in southern Anhui, will be demolished. The blasting time is from 9:00 am on May 24 to 5:00 pm on the same day. The construction unit of the blasting is responsible for Shaanxi Hongan Blasting Engineering Co., Ltd.

　　On the afternoon of May 23, the reporter came to the Weinan Thermal Power Plant. There were a large number of construction machines such as excavators on site, and several staff members. Dong Xushan, deputy director of the Engineering Management Department of Shaanxi Hongan Blasting Engineering Co., Ltd., said that before May 24th they were doing safety measures, such as the large mounds on the north side of the chimney, called the shock ditch, because on May 24, the chimney It is to the north. These mounds are for buffering, reducing the vibration caused by the fall of the chimney after blasting, and the damage of flying stones to the surrounding residential areas. For safety, on the morning of May 24th, they first conducted a test shot to see if the line was conducting. Whether the explosive connection was turned on or not, and whether the detonator was turned on, once again determined whether the design was reasonably optimized. The blasting project belongs to the Class A blasting operation project, which is the first implementation of the Class A blasting operation project in Weinan.

　　The blasting operation items are divided into four grades: A, B, C, and D. The A grade belongs to the highest level of blasting projects. The operation of the Class A blasting operations has high requirements for qualification, technology, and safety. The Class A blasting operation project means that the environment of the blasting operation is very complicated. The demolition of the building exceeds ten floors, the height of the building exceeds 30 meters, the height of the chimney exceeds 80 meters, the height of the tower exceeds 50 meters, and the first and second level water conservancy and hydropower hubs Main building, cofferdam, dam and water retaining rock. The blasting chimney is a 110-meter reinforced concrete chimney, which belongs to the Class A blasting operation.

　　On May 24 (Tomorrow), the historical moment of the blasting chimney of Weinan Thermal Power Plant, "Hua Shang Bao" will invite blasting experts to interpret the technical difficulties of the blasting. Interview with Zhang Chunxi, the former director of the Weinan Thermal Power Plant, recalling the glorious history of the thermal power plant.
