"Steel Giant" to help, this national project set a new record

Wuhan Evening News, September 23, September 23rd, the national major water conservancy project in Anhui — the on -site excavator of the Huailu River shipbuilding project is being demolished. It is learned that the project will have the conditions for submission and acceptance at the end of October.

The project's ultra -high gate wall uses the "Iron Giant" to set a new record.

Gujiang Jihuai Project is a major water -saving water supply project for accelerating construction. The Lujiang Shipbuilding Project is a key control project of the project. The gate of the gate is 14.5 meters high, and 20 symmetrical sections on both sides are accumulated equivalent to building 100 floors.

According to Li Maohua, the chief worker of the project, according to the routine layered pouring process, each layer is poured 3.3 meters. It takes 5 times to pour it to the top of the wall. It is calculated on the template for disassembly, concrete pouring maintenance, etc. The construction of the construction will take at least 5 days. From the perspective of the inverted construction plan, at least 0.4 floors are completed every day. In fact, it can only be completed at most 0.2 layers a day, and the construction period is very high.

Li Maohua thought that if he could make a "steel giant" to help.

Due to the lack of mature experience in the overall pouring construction of ultra -high gate walls, Li Maohua led the team to widely investigate a number of domestic shipbuilding projects in China. The construction of the gate wall is used to use the "hydraulic automation overall one -time pouring" process, which provides a comprehensive guarantee for the construction period, safety, and quality.

At the construction site, the pump trucks on both sides can be pumping on the middle of the gate. The gate walls on both sides are provided with 6 string of cylinders with a range of 3 meters, which can be uniformly poured from the bottom to the top of the template. Different from the previous layers and different poured processes on both sides, the "Iron Giant" allowed the gate wall to experience the construction process of symmetrical synchronization and overall pouring. The construction efficiency was improved. The construction period was 60 days in advance compared to layered pouring.

"The Lujiang ship gate project adopts a new technology of intelligent construction of the vessels, creating a new record for the first one -time poured by the 14.5 -meter gates in China, and it also effectively improves the construction efficiency of the project." Li Maohua said.

Yinjiang Jihuai Project (Anhui Section) is the "No. 1" project in the infrastructure construction of Anhui Province. It is known as the "South Water Diversion" project in Anhui. After the project is completed, it can meet urban and rural water supply, navigation, flood prevention, and improve the nest lake and Huaihe water ecology. Environmental needs, with functions such as diversion, navigation, flood control.

The project started construction in early 2020. The chief of the ship gate was 240 meters, 23 meters wide, and a height of 16.95 meters. According to the standard of the III ship gate, the design of the ship was designed to be thousands of tons, which can take into account 2,000 tons of ships.
