Xiaoqinghe Reinstallation Project

In the past few days, the Shandong Qinghe Rehabilitation Project Jinan Port's main urban port area is lively. The builders are carrying out the construction of the transmission network pipeline, marking the "nervous system" of my country's largest inland shipping project -the construction of smart channels has been fully opened. On the banks of Daming Lake, the former residence of Qingzhao, the Xiaoqing River, which originated from the four Dasquan groups in Jinan is about to usher in a new life.

In 2019, Railway Construction Investment was the leader of the consortium. The first “Kuchu Direct” large channel, the largest project in my country ’s river channel investment, the largest construction content in Shandong Province, the most complicated project ... a series of labels have attracted much attention.

In the first battle, the Jiexie won the emergency flood prevention battle

On June 25, 2020, the last section of the Shouguang section of the Xiaoqinghe FAW project was successfully completed, marking the completion of the flood prevention project of the project, and successfully completed the node target tasks determined by the Shandong Provincial Party Committee and the Provincial Government.

Because it belongs to the plain river, the original Xiaoqing River was blocked, and the drainage was not smooth. In 2018, the typhoon of "Wormia" and "Lichma" in 2019, the flood disasters in the Xiaoqing River Basin were serious, causing a major loss to the lives and property of the people along the river. A total of more than 1.28 million people in the two years, and the direct economic losses reached more than 62 billion yuan. In order to effectively improve the flood prevention standards of water conservancy facilities, and to take root in early root causes, the comprehensive management of flood prevention in the Xiaoqing River was listed as the "number one project" in 2020 by Shandong Province.

Digging and mud integrated twisted ships

In order to achieve the goal of expanding the 113 -kilometer rivers above June 30 to achieve the width expansion of the 23 -meter -bottomed river, the goal of the full disconnection of the 56 -kilometer rivers below the Jinjiaqiao gate, the China Railway Construction Port participated in the construction of the Railway Construction Investment Organization The Aviation Bureau, China Railway Construction Bridge Bureau, China Railway 14th Bureau, and China Railway 25th Bureau quickly adjusted the construction plan, coordinated the prevention and control of the epidemic, and reached the production. There are 2153 machinery (sets) such as boats, long -arm excavators, and mud refutation, and the governance principles of "upper storage, middle stagnation, and lower row" and the governance ideas of "interception, expansion, flood division, and tail tail". 12.6 million cubic meters of dry digging and 12.43 million cubic meters of dredging were successfully realized to achieve the goal of comprehensive management of flood prevention in 2020.

If the long -term Qinghe Qinghe is a wonderful music, then the two -seater gates and 4 boat brakes are the beats of the music control of music.

The new Chaizhuang section under the 25th of China Railway Twenty -five bureaus is the first restraint gate in Xiaoqinghe. The gate is composed of upstream and downstream connection sections, gate sections, and anti -power tank sections. During the construction process, the gate was only 8 meters away from the water transfer pipeline of the South -to -North Water. It not only had to discharge 17 meters long and tall templates on the original river channel of the Xiaoqing River, but also needed to pour 430 square meters of concrete in the construction of the gate. The group established a 297 -meter -long diversion before and after controlling the diversion of Ming canal to the other side; on the other hand, they played 78 water wells around the foundation pit and dug the original river soil layer 7 meters low for 7 meters low. And concrete pouring, which is equivalent to adding a "waterproof film" on it to achieve the purpose of waterproof and drainage and rapid construction, creating favorable conditions for engineering construction.

The Jinjiaqiao ship gate undertaken by the China Railway Construction Aviation Bureau is the first completion of the ship's first -site main body. It is constructed according to the standard of the class II vessels. The effective size of the gate is 280 meters long, 34 meters wide, and more than 10 meters high. It is of great significance to drive local economic development and promote diversification of tourism after completion. There are 4 boat brakes across the Xiaoqing River re -flight project. All the ship locks are located in the Yellow River Basin. The soil quality is mainly sandy soil and viscous soil. It is difficult to excavate. In order to solve the construction problem, the participating units first set up nearly 100 water pipe wells in the main structure of the ship gate to successfully reduce the water content of the soil before the soil excavation; Construction templates to form a construction running auction, ensuring the construction progress of the structure of the gate. At present, the main body of the four ship gate has been basically completed and began to enter the gate installation stage.

The two major themes of green development are comprehensive optimization of the channel design and construction

The channel engineering is another focus of the construction of the Xiaoqing River. According to the plan, Xiaoqinghe needs to construct 169.2 kilometers of Class III channels that can navigate 1,000 tons of cargo ships. The minimum standard is 3.2 meters deep and 45 meters width.

During the construction of the channel, the builders are optimized by reference to the ingredients and processes commonly used by the slope protection of the Beijing -Hangzhou Canal. It is changed to the construction of concrete slopes that are easy to construct and save costs. The process has greatly improved construction efficiency.

The river water system is an important part of the ecosystem. Traditional gray -white concrete slope protection seriously damages the interception and adsorption of the biological system on water pollution substances, which can easily cause worsening water environment. In order to strengthen the ecological protection of the river water, the III Courtyard adopts the combination of "prefabrication+greening" on the slope design of the Xiaoqing River, that is, set up an ecological chain block on the soil slope above the normal water level. The use of grass -planting slopes perfectly combines ecological environmental protection design and ecological protection design to coexist in engineering protection and landscape.

The G18 and G516 bridges have many types of bridges at the Xiaoqing River on the construction site of the Xiaoqing River. In order to meet the requirements of the III channel navigation, the builders will be built and rebuilt 39 bridges across the board. The China Railway Construction Bridge has played a professional advantage of bridge engineering, builds a large -scale box beam prefabricated plant in advance, is equipped with equipment personnel, rationally optimized the process, and realized the rapid advancement of "demolition and re -renovation". At present, 27 bridges across the line have completed the lower structure construction, and 9 bridges have completed the upper structure construction.

Smart system blessing pioneering channel operation new model

At the beginning of the project, the project attached great importance to digitalization and intelligent construction. The Channel Command Center used the most advanced digital twin technology to create the virtual model of the small Qinghe channel physical entity in a digital manner, which was basically the same as the real Xiaoqing River channel and ship gate scene. The two -way data iterative interactive optimization of the "fusion of reality and reality" has greatly improved the precise positioning capacity and emergency response efficiency of the intelligent management of the channel.

Xiaoqinghe Smart Channel Concept Map

The digital channel engineering of this project mainly includes a perception network (Channel Video Monitoring System (CCTV), a remote reporting system for the benchmark, hydrological remote reporting system, a vessel meteorological collection system, a ship traffic management system (VTS), and a ship automatic recognition system (AIS) And electronic channel maps), transmission network system, hardware and computer room supporting facilities, ship gate control system engineering projects, external electricity connection project construction, etc., are undertaken by the China Railway 14th Bureau. People -oriented Xiaoqing River channel smart management and service goals.

In addition, in terms of joint scheduling of the ship gate, after the small Qinghe resumed navigation, the ETC passed the gate was canceled, and all its functions were combined to the "Palm Little Qinghe" APP software. The crew can be reported in advance through the "Palm on the Qinghe" APP, which can realize a report to Hong Kong and passing the gate at one time. The payment method supports WeChat and Alipay. The efficiency of the ship's gates.

According to the construction period, the Xiaoqinghe Re -Airlines Project will be completed in June 2023. After the completion of the project, it will become the inland water transportation channel that runs through the industrial corridor in the central part of Shandong Province.
