Goodbye, "Gas Bag" on Dadu River Road!

The No. 1 air cabinet was only removed for one week. At 10 am on July 28, the last wall board of No. 2 Qi Cabinet was completed, marking the two dry air cabinets, which were once known as Asia, and the main structure was completely completed.

All the structure of the air cabinet main body is demolished

"Report Yu Director, the equipment hanging conditions are already available, and the request is lifted."

"Agree to hang up."

"Received, the driver No. 3 slowly lifted."

As the lifting instruction was issued, the steel wall plate of the last No. 2 air cabinet was slowly lifted, and slowly tilted down. With the "Gas Bag" with Dadu River Road for more than 20 years, watching them from the construction, putting production to the demolition, Chen Hao, the webmaster of the Daduhe Road Storage Station of Gas City, Shanghai Gas City, was very complicated, and silently raised his mobile phone to freeze. This historic picture. "At this moment, it is more expected than reluctance." Chen Hao said that the "gas bag" of Dadu River Road witnessed the era of gas development. After natural gasization in Shanghai, it still served as a reserve gas source. More than years.

After 7 months, the demolition of the "Gas Bao" demolition of Daduhe Road encountered an epidemic and temporarily stopped. After the construction was restored, it encountered a rare high temperature. Under the test, the tunnel shares that undertake the demolition project Shanghai Nengjian Shibei Engineering Company, overcome various difficulties, optimize cutting and lifting operations, and accelerate the progress of the project. When cutting the steel wall board, the construction party found that the cutting guns used by the operation were too short. When cutting, the operators should not only be baked at high temperature, but also tolerate the high temperature when cutting guns. "After the company understands the situation, a optimization meeting was held, and finally decided to extend the length of the gun tube." We found the manufacturer to customize the gun and extend the original length of 80 cm. It's right. "Ye Xiangyi, the person in charge of the scene.

Special soft ladder used by the construction personnel when cutting the wall board

Considering that the air cabinet itself is made of steel, at high temperature, the temperature of the steel plate can reach above 50 ° C, and the construction party has strengthened the on -site protection and heatstroke cooling measures of the operators. "We have improved the level of protective supplies. For example, the shoes are buying a thick bottom, there is sufficient salt water supply every day, and the company also equipped us with heatstroke and cooling materials." The construction staff told reporters.

Depending on the height of the wall of each cabinet, and the identity of the sink, the construction party adapts to local conditions to adjust the pedal of the special soft ladder to the same as the slot steel, which is convenient for the operators to improve the work efficiency.

In order to cope with the adverse effects brought by high temperature, the construction party also adjusted the operation time, adopted the operating mode of "two ends, intermediate rest", and promptly pay attention to the weather forecast of "Shanghai release". Adjust or suspend operation. "The red warning is absolutely not allowed to be constructed. If the orange warning will see the temperature, the morning operation is concentrated at 5 am to 9:30 in the morning, and the construction will be carried out at 3 or 4 in the afternoon." Said Yu Hongwei, director of the project supervision team, said.

Last wall board landing

The construction party also further optimizes the construction plan, and the step -by -step operation to cross -operating operations to speed up the demolition work. "We merged the same demolition process of the two air cabinets. The same procedures of each gas cabinet operated synchronously to save time and ensure the coherence of workers' operations." Secretary Cheng Wensing introduced.

The residents of Building 39, an Oasis Apartment, which are separated by the "Gas Bag" of Dadu River Road, also witnessed the launch of the last wall board in the window. The couple were very excited and immediately sent a circle of friends. "It was finally removed today, and now the sight of my window is very good." Zhu Fusheng, a resident, said happily.

Looking at the demolition work that is expected, the resident Hua Baojin is both surprised and amazed, and we look forward to the new appearance of the future. "Since the recovery of construction in June, it has been a day, and I witnessed the" gas bag '"disappearing'. It is really amazing. We feel that the government is increasing and promoting. .
