In the early Ming Dynasty, there were frequent floods in the upper reaches of Xiaoqing River. 1403- 142 1 (Yongle period) started embankment construction. 1465 (the first year of Chenghua), the river was opened and the flood was introduced into the Daqing River. 1473- 1475 (from nine to eleven years of Chenghua), comprehensively dredged 25 1km from Licheng to Haikou in Xiaoqing River, and built 38 sluices. 1533 (in the 12th year of Jiajing), the river channel from Boxing to Licheng was dredged 150km, and the embankments of Boxing and Le 'anjing were built over 90km. 1544 (the 23rd year of Jiajing) dredged the river between Zhangqiu and Boxing112.5km ..1573-1602 (the Wanli period), pumping was determined at the lower pumping weir in the north, and all of them were pumped into Daqing River. Xiaoqing River from Licheng to Zhangqiu is gradually silted up, and Juye River and Jiangxiu River, which originally flowed into Xiaoqing River, are also the largest rivers in Qinghe. Since then, only the original Luohe River in the upper reaches of Xiaoqing River has flowed eastward along the old channel of Xiaoqing River. The reach from Zhangqiu to Taotangkou in Qing Dynasty was dredged on 1686 (25th year of Kangxi). 1716-1718 (Kangxi 55-57) Xiaoqing River flood diversion. The branch vein ditch starts from Zhangba Army in the southwest of Gaoyuan City, and flows into the sea from Boxing to Le 'anhui Xiaoqing River. 17 19 (in the fifty-eighth year of Kangxi), the flood was diverted from the river course of Xiaoqing River Nankai Reserve, starting from Mada Lake in the west and pouring into the sea from Huichengbo, Shicun Town and Dongbeiwu in the east longitude. Formed a branch canal, Xiaoqing River, Reserve River three rivers parallel into the sea situation. 1772 (thirty-seven years of Qianlong), 13 county all the main expenditure ditches of migrant workers were ditched, with a width of 20 meters and a depth of 2.5 meters, and lakes and clear waters were dredged to prepare for flood detention. At the same time, the Xiaoqing River in Zhangqiu County was dredged and the levee from Wanjiakou to Junzhangba was repaired. After the regulation, Xiaoqing River below Zhangqiu will be discharged into the sea by river (clear water berth), ditch (branch vein ditch) and ditch. The Xiaoqing River above Zhangqiu is still blocked, and the upstream tributaries still enter the Daqing River. 189 1 year (in the 17th year of Guangxu), the upper branch ditch was widened and embankmentd to connect the water of Licheng and Zhangqiu counties in the upstream, and the river was diverted to Longwangwa in Boxing. Longzhuwa Xiakou, Jinjiaqiao in Boxing County to Yangjiaogou Haikou, dredging Xiaoqing River for 55 kilometers. The width of Heshangma Lane is10m, and the depth is 3.3-4.3m. The embankment has been excavated, and the silver cost is198,000 yuan. The branch ditch below Boxing is still reserved as a branch river to divert the flood of Xiaoqing River. 1892 (18th year of Guangxu) continued to harness, taking Jinjiaqiao directly to the west, digging the Xiaoqing River main stream in the depression between the tributary ditch and the reserve river, passing through Boxing, Gaoyuan, Xincheng, Changshan and Zouping counties to Caojiapo in Qidong County, with a total length of 48.75km, and the river surface is still10m wide and 2m deep. From below Jinjiaqiao, from the former site of the reserved river to Qiao Liu, a tributary was opened to discharge the river water in the upper reaches of the Great Lakes and introduce it to Zheng He. The tributary is12km long, 6.7m wide and 2.3-3m deep. The two rivers are supported by 245 thousand silver. Reaches in Licheng, Zhangqiu and Qidong counties have also been selected, so that Xiaoqing River can be unblocked and shipping can be resumed. Ships can go directly from Yangjiaogou to Huangtai Bridge in Licheng, and the flood in the basin has been alleviated, which is a relatively successful treatment. 1904 (30th year of Guangxu), Mulimen was built on the east bank of Yufu River in the northwest of Licheng, which led the Yufu River to flow eastward into Xiaoqing River and extend from Xiaoqing River to Mulimen in the west.
1930, the Xiaoqing River Administration Bureau was set up under the Construction Department of Shandong Province to draw up the Xiaoqing River regulation plan. The following year, the "Temporary Engineering Committee for Harnessing Xiaoqing River" was established to survey Xiaoqing River again, and the Outline of Xiaoqing River Project in Shandong Province was drawn up, including the regulation of the main stream, the regulation of water sources and tributaries, the regulation of Haikou and the construction of docks. 193 1- 1933 dredged the Baotu River, Black Lake and other springs near Xiaoqing River, deepened Baotu Spring Pool by 1 m, and drilled 6 new springs. Expand the Black Tiger Spring Pool, dig to a depth of1.2m, set up a measuring weir, and add two spray tigers. Broaden and deepen Gate No.5 and No.6 to the main stream of Xiaoqing River in Lin Jiaqiao, and build dikes on both banks. Construction of two dams, Wuliu and Bianzhuang. Wuliu Sluice Dam Project includes 1 rockfill dam built in the middle section of the newly excavated Moon River in the south of the sluice. The lock box is 100 m long, the lock width is 9.2 m, the upper lock height is 3.85 m, and the lower lock height is 7. 15 m, which can pass through a tugboat and two barges at the same time. It is the first modern ship lock in Shandong Province. Bianzhuang sluice box is 80 meters long and 9.2 meters wide, which can accommodate a tugboat and barge. Wuliu sluice was started in May of 193 1 and completed at the end of August of the following year. Bianzhuang sluice was started in May 1932, completed in the same year1October 165438+, and officially opened to traffic on October 25th.
After the establishment of People's Republic of China (PRC), during the period of 1956- 1964, the main stream of Xiaoqing River in Zhangqiu County was dredged and diked, and nine drainage culverts were built successively. The urban section of Jinan City has been re-embanked, and the length from Huangtai to Yawangkou is 27 kilometers. Three drainage culverts have been built, and the dredging village and Wuliu sluice have been rectified. Xiaoqing River in Huimin area has also been rectified, and the beach below the estuary is also ready, with a length of 22 kilometers. 1in the spring of 1966, the province allocated 6 million yuan to harness Xiaoqing River on a large scale, and excavated a flood diversion river with a length of 84.5 kilometers and a width of 700 meters from the flood diversion mouth east of Taotangkou on the north bank of Xiaoqing River to Luqinggou mouth. Embankment construction on the north bank, with an average elevation of15-16m and a flow of 700 cubic meters per second. The construction was completed in May by 30,000 migrant workers from Zouping, Gaoqing and Boxing, and the earthwork was 4 million cubic meters. 1967 transferred 7,700 people to Zouping county, reinforced the levee to the middle levee of Shangdaokou, and completed 3.8 million cubic meters of earthwork from Xinghua estuary to Beiying Qitan. After the diversion of the Red River, the main stream of Xiaoqing River flows eastward from Taotangkou to Luqinggou, forming a situation of three dikes and two rivers.
Xiaoqing River Basin 1976 was listed as a key development area in Shandong Province to realize a strong industrial province1mid-March 1985, 1977, the Shandong Provincial Party Committee decided that Xiaoqing River Basin was a conference theater for farmland capital construction in the whole province. Zhangqiu county took the lead. In June of that year, 50,000 migrant workers were transferred. According to the unified arrangement of the provincial party committee to govern Xiaoqing River, Zhangqiu County completed the project of beach cutting, dike building and dike widening in 40 days. The dike spacing is 330m, the estuary is generally 70m wide, the river bottom is10-13m wide and 5.0-7.0m deep. The right dike is 1 1.9 km long, 3-4m high and10m wide. Because there is no unified management of upstream and downstream, the benefits have not been fully exerted.
1978 a leading group is composed of provincial planning commission, construction commission, agricultural office, water conservancy, transportation and other departments. * * * Together, the Xiaoqing River comprehensive management plan was formulated to comprehensively solve the problems of flood control, waterlogging elimination, irrigation, shipping, environmental protection and war preparedness. It is planned to complete the widening of Xiaoqing River dike distance, river widening and excavation of flood diversion canal in 1979- 1982 to improve the flood control and drainage capacity. Xiaoqing River Campaign Office in Shandong Province was established in September, 1978, with Li Zhen, deputy secretary of Shandong Provincial Party Committee, as the director of the office. On June 5438+ 10, Huimin District organized the construction of migrant workers in Zouping, Gaoqing, Boxing, Guangrao, Zhanhua, Binxian and Huimin counties130,000. By the end of June 5438+February, the excavation of the auxiliary channel of the flood diversion river from Zhangbei Highway Bridge to Luqinggou was completed, with a length of 53.4 kilometers, and at the same time, the north dike of the flood diversion river was raised and thickened by 56 kilometers. After treatment, the flow rate of each trough is 200 cubic meters per second, the maximum bottom width is 38 meters, the left beach is 70 meters, the new dike top width is 15 meters, * * * earthwork 155 10000 cubic meters, the number of workers1030,000, and the investment/kloc-. Because the outlet position of the auxiliary trough below Lu Qing ditch was not fully brewed in advance, Guangrao and Shouguang counties had different opinions, and Shouguang could not dig for 4 kilometers. Zhangbei Highway is more than 365,438+0 km, and has not been excavated due to the limitation of funds. The construction of the project was stopped in February 1980, and the flood control benefit has not been brought into play so far. However, in the Yellow River Diversion Project, 34.8 kilometers of flood diversion channel is used to transport water. Located in the upper reaches of He Zi River in Taihe Township, Zichuan District, Zibo (formerly known as Jinjishan Reservoir). The control basin covers an area of 780 square kilometers. Total storage capacity/kloc-0.02 million cubic meters, Li Xing storage capacity of 74 million cubic meters.
1960 started construction on February 4th, 196 1 stopped construction in February, 1966 1 resumed construction in1October, and ended in September 1972. From June 1976 to the end of June 198 1 Dam reinforcement, excavation of east spillway and sluice construction of west spillway were completed. By 1985, the reservoir project has completed 8.86 million cubic meters of earthwork and 48,000 cubic meters of concrete. The accumulated national investment is 39.34 million yuan.
The main dam of the reservoir is a sand shell dam with clay core wall, with a length of 760m, a maximum dam height of 48.76m and a crest width of 8m. The auxiliary dam is a homogeneous earth dam with a length of 422 meters, a maximum dam height of 32.77 meters and a crest width of 8 meters. There are five gates in the west spillway, with a maximum flow of 4668 cubic meters per second. The East Spillway has a dam with a width of 6m and a length of 32m, with a maximum flow of 3748m3/s.. The maximum flow of the water conveyance tunnel is 65.4 cubic meters per second.
The design flood control standard of reservoir is once in a hundred years. The designed irrigation area of reservoir irrigation area is 400,000 mu, and the effective irrigation area is1570,000 mu, which can supply water for 50,000 people.
