1962 In May, after the Central Water Conservancy Inspection Team went to Shandong to inspect the water conservancy project, it made the following decision on the Wohushan Reservoir Project: "In the long run, it is not necessary to continue the construction of the Wohushan Reservoir according to the original design, but the current scale will suffice. Now the total storage capacity is 68 million cubic meters, and the flood control standard comes once every 300 years. The bottom of the flat spillway can store about 22 million cubic meters of water, which can meet the downstream requirements. "
1962 10, Shandong Provincial People's Committee suggested that the design index of Wohushan Reservoir and the development scale of irrigation area should be large, and the Provincial People's Committee agreed to rebuild the reservoir to reduce its storage capacity, from large to medium. According to the spirit of the central government, provinces and counties on the reconstruction of Wohushan Reservoir, the dam was reinforced and repaired for the first time in 13 1.5m and the width of dam crest 7m. During the four years from 196 1 to 1964, the state invested a total of10.2 million yuan in the safety protection of Wohushan Reservoir, and completed earthwork10.34 million cubic meters, with 350,000 person-days, mainly including stone masonry protection and scour prevention of spillway. During the eleven years from 1964 to 1975, the annual maintenance fund was 804,000 yuan, 69,000 cubic meters of earth and stone were completed, and158,000 man-days were completed.
The reinforcement project of Wohushan Reservoir started in April 1976 and ended in June 1985. After ten years of uninterrupted construction, it was basically completed according to the design scale. Earth and stone works 2135,900 cubic meters and concrete 43,600 cubic meters were completed, and 6123,700 person-days were completed, with a total investment of 2 1.9 1.84 million yuan.
When the reservoir was built, all the migrant workers in Licheng County 14 commune were mobilized, and Changqing, Feicheng, Taian and other counties all sent migrant workers to support it. Teachers and students of colleges and universities in Jinan, PLA officers and soldiers, factory workers and government cadres also participated in the construction. At the height of reservoir construction, there were about 30,000 sunrise workers. 198 1 year. Wohushan Reservoir has achieved self-sufficiency in operation and management funds.
In 200 1 year, Jinan Water Conservancy Bureau carried out the planning and design of the reservoir capacity-increasing project on the basis of the successful test of reinjection of Wohushan Reservoir into Yufu River to protect the spring and replenish the source. This project is invested and constructed by Jinan Water Conservancy Bureau. Construction started in May 2002, and mechanized construction was completed in September of that year.
From May to June, 2004, 65438+February, Jinan Water Conservancy Bureau invested more than 9 million yuan to rebuild the flood control highway built in the early 1980s.
In 2004, Jinan Water Conservancy Bureau completed the replacement of dam safety monitoring system, which was jointly designed, developed and installed by Nanjing Hohai University and Shandong University.
In April, 2005, Jinan Water Conservancy Bureau invested in the construction of a remote video consultation system for reservoirs, and installed nine far-infrared video facilities at key positions in the upstream and downstream of the reservoirs, realizing synchronous operation with Jinan Municipal Bureau's Defense Office. Jinan City Defense Office can keep abreast of the water level, storage capacity and rainfall of the reservoir at any time, with a total investment of more than 9 million yuan.
On March 2, 20654381day, according to the information provided by Jinan Water Conservancy Bureau, the water level of Wohushan Reservoir was 123.49 meters above sea level, and its storage capacity reached 32.36 million cubic meters. On September 30th, 20 15, the reservoir capacity was only119.28 million cubic meters, and the water level was only 1 17.97 meters above sea level. This means that the amount of water in the reservoir is almost twice that of last autumn. All this is due to the "West-to-East Gas Transmission Project" that started operation at the end of last year. It is the Wohushan Reservoir Water Transfer Project of Yufu River that helps the Yangtze River and the Yellow River to realize water transfer. At that time, the Yangtze River water in Jiping main canal and the Yellow River water in Pingyin started from Jiazhuang sluice, climbed the Yufu River step by step, and reached Wohushan Reservoir to replenish water.
