The flood season is here. Today we will pay attention to the flood prevention "artifact" in the city.

This station came to the ancient city of Lanxi. It was located in the middle reaches of the Qiantang River Basin. The three rivers of the Jinhuajiang, Lujiang, and Lanjiang River met here.

From 1950 to 2021, a total of 156 floods in the water level in Lanjiang had a super warning water level. The urban flood prevention became a must -answer in Lanxi.

On June 25, 2017, Lanxi encountered a flood for 20 years

In recent years, with the "artifacts" of Lanxi City Flood Control, the "artifact" of Lanxi City has continued to be new.

Along the ancient city wall of the right bank of Lanjiang, we look for these unique flood control "artifacts "-

Steel glass flood prevention wall

The flood-proof wall completed in April 2021 is 851 meters long, and the water-resistant glass wall blocking process of 1-1.5 meters height is 1-1.5 meters, which cleverly integrate flood control and ancient city culture.

The 57 mobile gates completed in 2014, with a total length of 640 meters, usually opened, which can be used for citizens to relax. When the flood came, the steel gate on the land section was closed for water blocking. According to Li Yan, the person in charge of Lanxi City City Defense Project, this is the first mobile steel gate in the country with patent protection.

Aluminum alloy flood prevention and insertion door

Lanxi's five city door caves are used for demolished aluminum alloy flood prevention. They are usually placed in the material warehouse. Before the flood is coming, it can be quickly installed according to the serial number to form a closed circle to resist the floods for the residents of the old town.

Li Yan told reporters that as of now, the total length of the flood prevention circle in Lanxi City was 37.44 kilometers in 50 years, and it has successfully resisted three times the super police flood.
