"The officials are endowed with fish and salt, and the people are rich in millet and wheat fields. The river has nine bends, and the green trees are full of thousands of chapters." More than 600 years ago, the Ming Dynasty poet Zhu Shan came to Xiaoqing River and wrote such a poem. At that time, the Xiaoqing River had abundant water, lush trees and beautiful scenery.
The Xiaoqing River restoration project will recreate the prosperity of this "golden waterway" in the past. After several years of construction, the main project of the waterway will be completed by the end of this year, making it suitable for navigation.
Is the water volume sufficient?
Xiaoqing River Renavigation Project is 169.2 kilometers long. It starts from Jinan, passes through Binzhou , Zibo , Dongying , Weifang , and ends at Bohai Bay . It is planned as a third-level waterway. It is an important "one horizontal" in the "one vertical and three horizontal" high-level waterway network in the inland waterway layout plan of Shandong Province. It is also the only waterway in Shandong Province that has the conditions for sea-river intermodal transport at this stage. It can realize direct transportation of , Haihe and . It is also the only waterway in Shandong Province. It is the first project in the history of water transportation construction with a one-time investment of over 10 billion yuan.
html On the morning of June 29, construction workers were laying transmission network pipes on the other side of the Xiaoqing River from the main port area of Jinan Port. As a "nervous system", this 169-kilometer-long transmission network is the foundation of Xiaoqing River's digital waterway.
"98 360-degree rotating pan/tilts provide full coverage of video surveillance in key areas; 10 sets of hydrological monitoring equipment monitor water level, water depth, flow rate and other parameters in real time." Standing by the Xiaoqing River, China Railway 14th Bureau Electrification Xu Zhaofeng, the company’s person in charge of the digital standardization project for Xiaoqing River’s resumption of navigation project, told reporters that Xiaoqing River will build a comprehensive port and shipping information application platform of “perception + digital + analysis + decision-making” to achieve “remote viewing, sitting management, and walking use”.
"To achieve normal navigation of 2,000-ton ships, the water depth of the channel must reach 3.8 meters. Judging from the hydrological monitoring situation in recent years, the water volume of Xiaoqing River can basically meet the navigation needs." Faced with the reporter's question about the water content of Xiaoqing River after its navigation To the question of whether it is enough, Wang Jianliang, director of the design and management department of China Railway Construction Investment Shandong Xiaoqinghe Development Co., Ltd., gave a positive answer. He said that the early project designers had fully considered this issue. The continuous water replenishment of Xiaoqing River mainly comes from urban gray water. Jinan alone discharges 1 million cubic meters of urban gray water to Xiaoqing River every day, which basically meets the needs of navigation.
In addition, rainwater during the flood season also provides strong support for Xiaoqing River to replenish water. "We have also set up a water pumping station and a water saving tank, which can reduce the amount of water released under the lock during the dry season, and the water flowing through the lock can be replenished again," Wang Jianliang said.
How much do you know about the convenience of going to sea?
On June 25, at the Huagou operation area of Gaoqing Port District, Zibo Port, Xiaoqing River, located in Gaoqing County, large vehicles shuttled back and forth, machinery roared, and the scene was a hot scene. At present, the main works of the wharf and flood control wall have been completed ahead of schedule, and the internal site hardening of the port area is being implemented.
The Huagou Operation Area of Gaoqing Port District of Zibo Port is located on the north bank of Xiaoqing River. The total investment of the project is about 600 million yuan. It plans to build 4 general and multi-purpose berths and corresponding supporting projects. The total length of the coastline is 330 meters, and the annual throughput is 3.2 million tons. . In the future, Gaoqing Port Area will use big data, cloud computing , Internet of Things and other technologies to create a ‘quasi-unmanned terminal’ with automation of operating equipment, visualization of data information, and intelligent production management.
Zibo has a complete range of industrial categories, many industrial enterprises, and high logistics pressure. After Xiaoqing River resumes navigation, Xiaoqing River is expected to become a major inland water transport channel that runs through the industrial corridor in central Shandong Province, and will also be an open channel for Zibo City to directly lead to the ocean.
Bohui Group is a large enterprise group integrating papermaking, chemical industry and thermoelectricity. The chemical raw materials raw salt required by the enterprise are mainly purchased from Shouguang Yangkou , the main sea salt production area in the country. At present, they are all transported to the factory by road; the main transportation ports for imported wood chips and coal are Longkou Port , Yantai Port and Weifang Port , and then transfer to the factory by road or road-rail combined transportation.
"The resumption of navigation on the Xiaoqing River will not only accelerate the flow of elements, but also bring more possibilities for the development of our enterprise. From the perspective of cost savings and efficiency enhancement, preliminary estimates show that after some raw materials are transported by water, the annual transportation cost can be saved by more than 10 million yuan," said Kang Peng, logistics manager of Bohui Group.
What are the advantages of water transportation?
In the lakeside operation area of Boxing Port in Xiaoqing River, the 850-meter-long and 5-meter-high flood control wall has been completed. It looks like a giant dragon lying on the bank of Xiaoqing River, adjacent to the dock berths and cargo yards. Construction is intensifying.
Du Yilong, project manager of Shandong Luqiao Boxing Port, introduced that the first phase of the Hubin Operation Area of Boxing Port Area is located in the northeast of Zika Village, Hubin Town, Boxing County. It plans to build a bulk cargo berth area, a general and multi-purpose berth area and a liquid bulk cargo berth area. There are a total of 21 cargo berth areas, covering an area of 2,860 acres, with a total investment of approximately 2.2 billion yuan. Up to now, the pouring of the dock wall has been completed, the road yard backfill construction has begun, and fire protection, water supply and drainage and other supporting facilities have also entered the construction stage. In the second half of this year, the project will complete the earthwork excavation of the harbor basin, installation of dock wall accessories, bidding and installation of port machinery equipment, and the base of the road yard to achieve operational conditions for navigation.
The reporter also learned that the first phase of the Lakeside Operation Area of Boxing Port Area plans to build eight 1,000-ton berths and 150-meter support system berths. The designed throughput capacity is 6.9 million tons/year. The main cargo types are grain, coke, and mining construction. Materials, wood chips, steel and containers, etc.
In the past ten years, enterprises along the Xiaoqing River in Binzhou have developed rapidly. Large enterprises such as Weiqiao Group, Xiangchi Cereals and Oils, Jingbo Petrochemicals have emerged, involving industries such as metallurgy, papermaking, chemicals, textiles, grains and oils, and the transportation volume has increased. Rapidly, the rapid rise in oil prices in recent years has greatly increased transportation costs.
Industry insiders believe that compared with other modes of transportation, water transportation has outstanding advantages such as large transportation volume, low freight rates, low investment, small land occupation, low energy consumption, and low pollution. In terms of energy consumption, the energy consumption per horsepower of water transportation is only 1/10 of that of roads and 1/2 of that of railways. In addition, the cost of freight pollution per 1,000 ton-kilometers has been reduced. The ratio of water transportation to railways and highways is 1:3.3:14.6, which plays an irreplaceable role in the long-distance transportation of bulk and heavy goods.
How many types of boats can run on the waterway
html On June 30, the rain for several days finally stopped. At the Wangdao ship lock site in the Dongying section of the Xiaoqing River renavigation project, two huge herringbone doors at the head of the lock were being installed. Zong Jiaxin, executive deputy manager of the project department, said that there are two gates at the upper and lower heads of the ship lock, which are key devices for controlling the water level in the entire lock chamber. The Wangdao Ship Lock Project is a nodal control project for the entire Xiaoqing River project. Technically, dry land excavation is used to build new locks. It is the ship lock project with the largest actual investment along the line. According to Zong Jiaxin, the Xiaoqing River navigation resumption project is designed with five control locks, including four ship locks. The channel construction standard is Level 3 (navigable for 1,000-ton ships). However, the project is in the planning and design stage. The navigation of channels, bridges and ship locks The scale has already taken into account the navigation conditions of 2,000-ton Haihe River direct ships, and will basically meet the navigation conditions of secondary waterways.
The first step in navigation is to dredge the channel. It is understood that the Dongying section alone has deployed 21 various construction vessels such as suction vessels, pile boats, and traffic boats to carry out channel dredging. The main channel dredging project was completed across the entire line and in all sections on June 21, with a total of 5.33 million cubic meters of earth dredged. . In addition, the Xiaoqing River Navigation Resumption Project has a total of 4 cascade locks along the entire line. It is currently the largest ship lock in domestic inland waterway construction and can allow six 2,000-ton ships to pass through at one time.
The shipping capacity of the Xiaoqing River after the resumption of navigation is not only related to the waterway construction standards, but also the type of navigable ships is also critical. According to Zong Jiaxin, there are currently four main types of ships designed for the Xiaoqing River resumption project: 1 tow 6, 1 tow 2, inland river 1,000-ton cargo ship and 60TEU container ship . The latter two ship types are not difficult to understand, they are single-hull cargo ships. The 1-to-6 ship model consists of a 272KW tugboat and six 1,000-ton barges , which can carry 6,000 tons of cargo at a time.The 1-top-2 ship type uses a 180KW pusher to push two 1,000-ton barges to carry 2,000 tons at a time. "In other words, although the waterway design standard is level three and the standard navigation is one thousand tons, a single load of 1,000 tons - 6,000 tons can be achieved through different ship types."
How powerful is the "engine"
html June 20 , Yangkou Town, Shouguang City , the S309 Houxin Bridge across the Xiaoqing River is being paved with asphalt and will be opened to traffic soon. The bridge is the longest bridge in the Xiaoqing River navigation restoration project, with a total length of 1,637 meters, a width of 25 meters, and two-way four-lane .
The Shouguang section is the most downstream section of the Xiaoqing River renavigation project. It starts from Laotai River, a tributary of Xiaoqing River, in the west and ends at Shouguang Yangkou Port in the east. The total length of the dredged-deep channel is 17.21 kilometers. S309 Provincial Road Houxin Bridge and Yangkou Bridge 2 will be reconstructed. A highway bridge and 41 cross-river cables and pipelines were constructed to straighten the upstream section of the Yangkou Fishing Port Bridge. At present, channel dredging, cable and pipeline relocation have been completed. The Yangkou Bridge, which started construction on August 13, 2021, is currently under construction on the two main piers. The installation of prefabricated beams at both ends of the approach bridge has been completed, and the overall project progress exceeds 70%. According to the plan, the main bridge of the Yangkou Bridge is expected to be closed in mid-October, and the ship will be put on trial on October 20. The clearance height of the Yangkou Bridge (the distance between the navigable water level and the lowest edge of the bridge span structure ) is 11 meters, and the clearance height of the S309 Houxin Bridge is 10 meters. When the Xiaoqing River is at its highest water level, it also ensures the smooth passage of sailing ships. "Housin Bridge is the most convenient transportation section from Weifang to Dongying. It takes at least 50 kilometers more to go around other roads and takes an extra hour. If you take the expressway, the expressway toll will cost about 200 yuan more." A person who often travels between Weifang and Dongying driver Zhou Weichun said.
After the Xiaoqing River resumes navigation, as Yangkou Town in the West Port District of Weifang Port, in addition to a significant increase in port throughput , new industries such as ship maintenance, material supply, raw material processing, and container disassembly and packing will also be derived. Service format. "River-sea combined transport will effectively promote the rational distribution of productivity, guide industrial agglomeration, and form an economic development cycle chain in which shipping drives logistics, logistics drives industry, and industry promotes cooperation, and becomes an important engine that effectively drives economic development along the line." Shouguang City Port and Shipping Services said Zhang Xingde, director of the center.
Shandong builds an inland water transport network that connects the river to the sea
The reporter learned from the Provincial Department of Transportation that as of the end of June, the Xiaoqing River restoration project had completed an investment of 10.989 billion yuan, accounting for 81% of the total investment. Among them, the waterway project has completed 95% of the total project quantity, the ship lock project has completed 80% of the total project quantity, and the bridge project has completed 74% of the total project quantity.
The Xiaoqing River resumption project adopts the PPP model. The China Railway Construction Investment Group consortium took the lead and won the bid. The cooperation period is 30 years, including a construction period of 3 years and an operation period of 27 years. The estimated investment is 13.59 billion yuan. The main construction contents include: construction of 169.2 kilometers of Class III waterways, reconstruction and expansion of 39 bridges (including the Zhangdong Railway Bridge), 4 new ship locks, 22 control locks, 481 water conservancy facilities across the river, and 32 river-crossing pipelines. , 264 cross-river cables.
After the completion of the Xiaoqing River Restoration Project, the flood control standard of the main stream of Xiaoqing River and the floodway will be raised from a once-in-20-year return to a once-in-50-years standard. The urban section of Jinan will reach a once-in-100-year standard, which will effectively protect the lives of residents on both sides of the Xiaoqing River. Property security. In addition, after the Xiaoqing River is resumed, the Haihe River intermodal transport can divert more than 40 million tons of bulk cargo volume every year, which is equivalent to building another Jiaoji Railway , greatly reducing logistics and transportation costs and effectively stimulating the economy of cities along the route.
In addition to the Xiaoqing River resumption project this year, our province will also accelerate the construction of waterway projects such as the upgrading and reconstruction of the main channel of the Beijing-Hangzhou Canal, the improvement of the Huxi channel, and the navigation of the Daqing River channel, and upgrade the main channel of the Beijing-Hangzhou Canal from 1,000 tons to 2,000 tons as soon as possible. tonnage, promote the expansion and upgrading of Jining Liangshan Port, Longgong Port and other ports, and strive to build an inland water transport network that "connects the river to the sea".
