Water Conservancy Development of Luocheng River

Luoqing River flows through Yongfu County, which used to be a necessary waterway for transportation between Guilin and Liuzhou. During the Republic of China period, you can still take a wooden boat to and from Guilin and Liuzhou. Later, because of land transportation, coupled with many dams in the river, the channel was blocked and abolished. To the end of the 20th century only in the county near the city, can still pass the wooden boat.

Luo Qingjiang Yongfu County, 57 kilometers long, the river is generally 40 to 60 meters wide; water depth of about 2 meters, navigable 3 to 5 tons of ships. Since ancient times is the county's main waterway. Down to the Lujia injected into the Liujiang River. 1958, Lujia County in the Riding dam construction power station, so the navigation is cut off. 1970 to build Longxi power station, the foot of the dam in the Jinshan, this route is only left under the Longxi dam to Yongfu County 4 kilometers, the passage of the 3 to 5 tons of small motorboats.

Luoqing River Luzhai County, 103 kilometers of waterways, north through Yongfu south of Liuzhou waterway, the main waterway for the territory. Output to grain, timber, local specialties for the bulk; input to salt, department stores, Suzhou and Hangzhou groceries and other commodities. The navigable capacity is 10 tons. Republic of 26 years (1937), the monthly operation of wooden boats to and from 40, 207 tons, 38 years, the operation of wooden boats up to 55, 320 tons. At the beginning of the liberation, the boat is still more. After the establishment of the county people's government, has repeatedly allocated funds to dredge the waterway, navigable capacity increased to 30 tons. 1952, to and from the operation of 110 wooden sailing boats, 548.4 tons. 1958 after the construction of Riding Luo Qingjiang River Barrage, the interruption of the north through the Yongfu waterway. 1968, the construction of the Jiangkou Power Station Barrage, the interruption of the south through the Liuzhou waterway. And because of the development of highway and railroad transportation, the Luoqing River waterway transportation has been sharply reduced. To 1987, only the county short-distance water transport, to timber and sugar cane in the season water transport is the main.

Shihua River Luzhai County, 67 kilometers of waterway, navigable 7-ton ships, and Luo Qingjiang River communication. Before the liberation, the foreign transport to timber, grain, tung, tea oil is mainly; input salt, department stores, Suzhou and Hangzhou and other commodities, Republic of China 26 years (1937), the day to and from the operation of wooden boats 10 to 15, 60 tons. On the eve of liberation, the day to and from the operation of wooden ships up to 24, 109.2 tons. After the establishment of the county people's government, the waterway has been further improved, navigability increased to 10 tons. 1957 construction of sickle bay dam, the waterway transportation stop, only a few wood water transport.

Luojiang River (also known as the Middle River) Luzhai County, 28 kilometers of waterway, and Luo Qingjiang communication. Republic of China in 26 years, the day to and from the operation of 33 wooden boats, 189 tons, the foreign transport to food, local products; import salt, department stores and other commodities. On the eve of liberation, 36 wooden ships of 153 tons were in operation. After the liberation, many dredging channel, navigable capacity increased from 3 tons to 7 tons. 1956, deer (Zhai) in the (ferry)) road opened to traffic, the waterway transportation decreased year by year, after 1970, the waterway transportation basically stopped. Yi River diversion hub project, in Lingui County, started in the winter of 1957, completed in March 1981. Divided into two trunk canals, the east canal to the east of Wan Tian Changling Dam as the first, connected to the Yi River on the east side of the tributaries of the small weir dam 15, 36 kilometers long. West trunk canal to the middle of the river dam as the head, connected to the west side of the Yi River on the history of the river dam, Penglai River dam, Zumiao River dam and Longjiang dam and other 20 large and small weir dam, 21 kilometers long. There are also two branch canals of 11 kilometers long, 6 bucket canals of 10.5 kilometers long, and 340 large and small ancillary works. The designed irrigated area is 53,300 mu, including 0.41 million mu of Wantian, 47,200 mu of Wutong (including Zhongyong), and 0.2 million mu of Dutou. In 1990, the actual effective irrigated area was 47,000 mu, including 43,000 mu of guaranteed irrigated area.

Wuluo Dam project, in Lingui County, is a subsidized water project of the East Main Drainage Canal of the Yi River, 700 meters downstream of the Wuhuo barrage. For the barrage wood pile pebble dam, 37 meters long, 2 meters high, 2.3 meters wide at the top. The diversion flow rate is 0.4 cubic meters per second. construction began in November 1965 and was completed in March 1966. Designed to irrigate 1,000 mu, the actual irrigation field 980 mu.

Luo Qingjiang Riding River Diversion Project, built in 1958. The project was approved by the autonomous region, by the Liuzhou Special Department of Water and Electricity Bureau of survey and design, earth dam, design flow 22.8 cubic meters per second, 42.3 kilometers of the total trunk canal, 98 kilometers of the trunk canal length, designed to irrigate an area of 146,000 acres, with a total investment of 8,587,000 yuan. On June 15 of the same year, mobilized 1,000 workers for construction preparations, on October 20, the project started in full, the construction of up to 60,000 people. 1960 spring, the head of the dam and the completion of the floodway, * * * cost 4.3 million yuan. Because the channel project is huge, but also worth the economic difficulties, September stop building.

High rock power pumping station, located in the town of Luo Rong high rock village at the foot of Luo Qingjiang River, the project is divided into three levels of pumping station, the first level was built in the village of high rock, reinforced concrete deep well pumping station; floor elevation of 67 meters, the outlet elevation of 93 meters, the net head of 27.8 meters, the cylinder diameter of 13 meters, the building area of 124 square meters; outlet 3, inner diameter of 1 meter, the tube length of 60 meters, the output of water 4.69 cubic meter per second.
