The current situation of Tongshanyuan
Tongshanyuan Reservoir is located on the source of Tongshan, a tributary of the Qujiang River. The dam site is 1 kilometer above Duze Town and 23 kilometers away from Quzhou City. The reservoir has a rainwater collection area of ??180 square kilometers, a total storage capacity of 171 million cubic meters, and a normal storage capacity of 121 million cubic meters. The reservoir is mainly used for irrigation, combined with power generation, flood control and aquaculture. It is designed to irrigate 250,000 acres of farmland in Qu County, Longyou County and two farms in Shilifeng and Tuanshi, benefit 40,000 acres from flood control, and install 3,750 kilowatts of hydropower. The average annual power generation capacity is 11 million kilowatt hours.
The reservoir hub consists of a dam, a flood discharge tunnel, an extraordinary flood discharge tunnel, a power generation water tunnel, a power station, a booster station, etc. The barrage dam is a clay-core sand shell dam with a dam height of 48.42 meters and a dam length of 252 meters. There is a power generation water transmission tunnel at the left dam head with a maximum flow of 135 cubic meters per second. There is a power station and a booster station behind the tunnel; normal flood discharge The hole and emergency discharge hole are both arranged on the right side of the dam, with the maximum discharge flows being 604 and 1028 cubic meters per second respectively.
There are 2 main canals in the reservoir irrigation area: the east main canal is 42.98 kilometers long, and the west main canal is 22.3 kilometers long: there are 25 main canals with a total length of 277 kilometers.
Tongshanyuan - the "Hongqi Canal" in Qubei. Tongshanyuan Reservoir, a place where the passion of several generations of Quzhou people has been ignited, part of the weight of loess once fell on the shoulders of those scholars who had just struggled to survive three years of natural disasters. Later county party secretary Xie Gaohua also struggled here. On the reservoir construction site, which used to rely entirely on wheelbarrows and people pulling on shoulders, Quzhou people forcibly piled loess from western Zhejiang into a gravity dam that is 48.42 meters high, 252 meters long, 8 meters wide at the top, and 249.18 meters wide at the bottom!
Quzhou City Tongshanyuan Irrigation District was built in the 1950s and 1960s. Due to various conditions at that time, the construction standards were low. After decades of operation, coupled with insufficient funds for maintenance and reinforcement, the efficiency has declined and aged. It is in disrepair and water resources are wasted seriously, affecting agricultural production. In 1998, the state included the Tongshanyuan Irrigation Area in the national large-scale irrigation area renewal and water-saving renovation plan. After many years of efforts, a total of 51 kilometers of main canals, 48 ??kilometers of branch canals, 3,933 meters of aqueducts have been repaired and anti-leakage treated, and a new Or reconstruct 132 canal bottom arch culverts and 45 bridge gates, and initially establish a standardized water-saving backbone engineering system in the irrigation area.
