In life, when you unscrew the faucet for a moment, the water source that meets you is flowing, but you have thought that most of this water source comes from the Longtang town section in the lower reaches of the Nandu River, where there is a water conservancy hub project, known as the Longtang Dam.
Built in the late 1960s and early 1970s, the Longtang Dam intercepted the flow of the lower reaches of the Nandu River, playing a role in flood control, flood discharge, power generation, connecting the two sides of the strait, irrigating agriculture, and now an important function is to provide important drinking water resources for Haikou City.
How long does a cement dam last?
The only dam on the lower reaches of the Nandu River will tell you in real time that it will be demolished due to functional aging due to the ups and downs of 50 years of use.
Longtang Dam has been in operation for half a century, and what is the current situation, you may wish to walk into Longtang Town to see this water conservancy dam that is about to disappear.
Longtang, Haikou Qiongshan Township, located in the lower reaches of the Nandu River west bank, east and Yunlong Town across the river, more than 40 miles from Haikou, Longtang for the water source protection of the important town, Most of the drinking water in Haikou City since extradition, in 2005, the Hainan Provincial Government will be nandu River Longtang section of the designated drinking water protection area as a drinking water first-class water source protection area.
龙塘胜景，龙塘大坝 The dam is located in Longtang Wei Dali Village.
Spanning both sides of the river, the imposing building is a beautiful sight of Longtang in the past 50 years.
Near the dam, the roar of the flood discharge was deafening and shocking.
Entering the dam, a huge wall stands in front of it, several meters high, and the wall is painted with red italic characters of "water conservancy is the lifeblood of agriculture", which is a quotation from Mao Zedong. It reflects the scene of that era, the revitalization of agriculture for a strong country, the construction of dams, and the heat of the sky.
The dam is reinforced concrete masonry, with drainage and power generation functions in the east and west, and the dam embankment in the middle is a cross-strait passage.
When the water level is super high, it overflows from the dam embankment, usually a passage between vehicles and pedestrians on both sides of the strait, the wide surface can accommodate a car and a motorcycle to pass each other, the dam surface is empty, there is no guardrail, walking in it, looking at its deep blue river water, the heart is cold.
On the wall columns of the east bank dam buildings, the relief font is prominent, which is very eye-catching: "Unite to strive for greater victories", "Prepare for war, prepare for famine for the people", "hard struggle, diligence and thrift to build the country", and other political propaganda slogans, which have the distinctive characteristics of the 60s and 70s.
Longtang Dam witnessed that era, in order to prosper agriculture, in the difficult years, relying on the spiritual will, built this water conservancy hub dam on the Nandu River, for 50 years, the years are strong, the dam does not move, even at this stage, it is still in normal use.
9亿打造，新龙塘大坝将成为南渡江标志性建筑 The life of cement dams is also limited, 50 years of Longtang dam has entered the phenomenon of aging, the existing risks are increasing day by day,
The state struck, and a dam that had been in service for 50 years was about to be completely dismantled in two years' time.
Re-invest 900 million yuan, 70 meters downstream of the original hub dam, to rebuild a Nandu River Longtang dam hub,
The engineering task of the new dam is mainly water supply, taking into account irrigation, ecological water replenishment, power generation, tourism, etc., and creating conditions for improving upstream flood control and drainage, and later taking into account shipping.
After completion, the new Longtang Dam will become a landmark building in the lower reaches of the Nandu River.
