Bailengzun Memorial Park

It’s a small and beautiful place, but it’s a pity that the surrounding area hasn’t been reorganized, but I think it’s still possible to walk around and learn about the great water conservancy facilities

A small park, you can park in the parking lot in front of Princess Anne's Garden, and then drill through the passage next to the culvert

The park is a bit small and seems to be surrounded by rubbish due to holidays. But it is really spectacular to witness the water conservancy construction during the Japanese occupation.

The Japanese government began to have the idea of ​​irrigation facilities in Showa 2 (1927), and obtained a budget of more than 1.45 million yen approved by the parliament at that time. Construction started in December of Showa 3 (1928), and in Showa 7 (1932) The construction was completed in September, and the water supply test was completed in September, and the water supply ceremony was held on October 14. In the ceremony, the director of the Ministry of Agriculture of Taiwan, Mr. Shiita Shikui, named the fortified waterway of the Dananzhuang Sugarcane Seedling Growing Institute "Bailengzhen". The water diversion road is 16.5 kilometers long. The entire Zhenlu road is located on the slope of the mountainside. Except for open channels, the main structures include 22 tunnels, 14 aqueducts and 3 inverted siphons. One of the inverted siphons is 346 meters long and has 1.2 meters across the valley, it is a huge water conservancy project. After the 921 earthquake, due to the damage to the road in the village, a new water pipe (painted blue) was built next to the farmland water conservancy project, creating a situation where the old and the new were juxtaposed. Because the siphon tube is inverted, the tube type is exactly the opposite of the principle of the siphon tube, and it is often called an inverted siphon tube. The inverted siphon is designed on the principle of connecting pipes. The green-painted steel pipe is climbing along the hillside. The difficulty of the project is beyond words. The beautiful and magnificent No. 2 inverted siphon is the largest inverted siphon in the Far East. It was selected in 1990. Ranked 26th in the National 100 Scenic Spots.

The siphon was damaged in the 921 earthquake, and now the old and new inverted siphons are side by side. The original design thickness of the steel pipe is 13mm. The new No. 2 siphon pipe was reconstructed after the earthquake disaster in 1991. It was officially opened to water. It crossed the Chuotengkeng River in Zhonghe Village, with a total length of 346.6 meters. The inner diameter of the steel pipe used was 1.22m. There are 452 steps in the northwest and 313 steps in the southeast. At present, the inverted siphon pipe of No. 2 in Tuotengkengxi can be seen here. The coexistence of old and new is the best case of historical preservation. In the past, the hillsides on both sides of the stream here were covered with yellow vines, and the aboriginal people often collected yellow vines here and returned with rich fruits, and then sold them to the Han people. To collect yellow vines, peel off the leaves and shells wrapped around the vines, and extract them one by one. Over time, this place was called the Rattan Pit. After the Han people entered the reclamation, they became a settlement and named it Tuotengkeng, and the stream was called Tuotengkeng Stream.

Water diversion facilities built for sugar production during the Japanese occupation era Bai Leng Zhen built using the principle of siphon Great water conservancy project Using U-shaped inverted siphon to introduce water from Dajia Stream to irrigate the Bailleng area When you come to Xinshe, don't go around and take a look The park is not big, but there are not many people, and the parking lot is full. There is a statue of Keno Isoda in one corner of the park In memory of the engineer who built this great project
