Twelve years of grinding a sword, Jiangsu Jihuaiqi New Chapter

Concerning Point News On July 30, the Huaihe River entered the second phase of the sea waterway project. As one of the 102 major projects determined by the National "Fourteenth Five -Year Plan", since the founding of the People's Republic of China, the largest water conservancy project in our province's single investment and project volume. An Lan, the people are safe? What role will it play in the economic market?

The flood prevention standard has been improved to 300 years of encounter

The climate of the Huaihe River Basin, dense population, and frequent disasters of water and drought, and the treatment of Huai has always been the top priority of the country's water treatment. Our province is in the lower reaches of the Huaihe River Basin, with sudden and extremely heavy rainstorms in the area. The problem of flooding is intertwined. Governance of Huai has always been the top priority of Jiangsu water management.

Thoroughly open up the Huaihe River into the seawater and crack the pain points of poor tails. Since the founding of the People's Republic of China, Jiangsu has invested more than 300 billion yuan to govern Huai, rectifying the water channel in the river, opening up the Yinhui waterway, and the first phase of the seawater channel project, forming a relatively complete flood prevention, moisture, waterlogging, staining, irrigation, irrigation, irrigation, irrigation, irrigation, irrigation, irrigation, irrigation, and irrigation. The water transfer engineering system has realized the flooding grooves, water supply and source of water supply, and drainage, which has changed the situation where the yellow disaster over the past hundreds of years has been changed.

"In July 2003, the first phase of the water channel project was just through the water, and the largest flood in the Huaihe River had occurred since 1954, and the maximum traffic in the lake was 14,500 cubic meters per second. The task has a total of 33 days, with a maximum leak of 1870 cubic meters per second, and a total of 4.4 billion cubic meters of floods. "Zhang Yazhong, former general manager of the Provincial Water Conservancy Survey and Design Institute Co., Ltd., recalled.

Nowadays, in terms of flood prevention, the Huaihe Water System has been leaked and combined, mainly leaked, forming Hongze Lake, going south, entering the river south, entering the sea in the east, and going north to the sea to go to the sea. The downstream flood control standard has reached 100 years. However, compared with the 300 -year -old standard requirements and high -quality development requirements determined by the national "Flood Prevention Standards", the Huaihe River flood control and waterlogging and waterlogging and waterlogging are not high. It still needs to expand the roads out of the flood to ensure the safety of flood prevention in the basin.

Yu Junjie, director of the Planning and Planning Division of the Provincial Water Resources Department, introduced that the second phase of the waterway waterway was based on the first phase of the project, which increased from 2270 cubic meters per second to 7000 cubic meters per second. , Increase the embankment on both sides of the strait, and the five -seater buildings along the expansion project, the planned period is planned for 7 years. After the completion of the project, the floods will be further expanded in the lower reaches of the Huaihe River, which can enable the flood prevention standards of Hongze Lake to achieve 300 years, improve the flood storage capacity of Hongze Lake, accelerate the flood leakage in the middle reaches of the Huaihe River, and reduce the pressure of flood prevention in the middle of the Huaihe River.

Building the embankment on the "tofu brain"

A few days ago, the feasibility study report of the second phase of the Huaihe River entered the seawater has been approved by the National Development and Reform Commission, and the total investment of the recovery project was about 43.8 billion yuan. Behind the start of the start is the work and hard work of the whole province for more than 10 years-

The Provincial Party Committee and the Provincial Government attach great importance to and actively promote it. Many special research associations have been entered into the second phase of the seawater. The Provincial Department of Water Resources and Provincial Department of Natural Resources, the Provincial Ecological Environment Department, and the Department of Transportation actively promote the requirements of land use, environmental assessment, aviation evaluation and other elements. Huai'an and Yancheng actively coordinate relevant departments to work together to promote project approval projects. In order to ensure that the research report is approved, it has the conditions for approval, and the Provincial Department of Water Resources has pre -set up two preliminary design and compilation of the start -up projects.

"In fact, as early as the first -phase project planning and design of the seawater channel in the 1990s, we focused on the vision scale. Due to the financial resources at that time, we decided to implement the first phase of the project and reserve the second phase of the project embankment. "Yu Junjie said," Under the guidance of the Ministry of Water Resources, in recent years, Jiangsu has conducted multiple in -depth research on the second phase of the project planning plan, and launched the preliminary work in 2010. After 12 years, it has finally started. "

Huai'an hub

Standing on the tower of the Huaihe River into the Huai'an Hub's Huai'an Hub, this famous "water interchange" gives a strong visual shock. I saw that the Beijing -Hangzhou Grand Canal and the Huaihe River entered the sea water channel. As soon as they were on the feet, after a brief intersection under the feet, they flowed into the distance in the distance, and in the channel of the Grand Canal, the shipbuilding ships shuttled slowly.

Zhang Yazhong told reporters that there are three major difficulties in the construction of the second phase of the sea waterway, two of which are in the hub. It is necessary to dig a temporary "Grand Canal" channel to navigate next to it, so that the ship is feasible, and then it can be constructed at the hub. After the construction is completed, the temporary navigation river can be canceled. Another difficulty in the total length of more than 30 kilometers at the entrance of the sea. Because it is located on the beach, the mud content is very high, close to 50%, and the geological conditions are very poor. There is a metaphor for "building the embankment on the tofu brain" Essence "But these issues have been encountered during the construction of the first phase of the project and mastered the relevant technologies. At that time, it was the first in Asia."

Add wings to the development of the Huaihe Ecological Economic Belt

The flood area around Hongze Lake is an important part of the Huaihe River Basin's flood control system. However, the flood dealerous area around Hongze Lake is not only a place for short -term stagnation floods, but also a place where 1.06 million people have lived for a long time. After the completion of the second phase of the waterway in the sea, if the flood is encountered in 100 years, the flood degradation area around Hongze Lake can reduce the amount of flood degradation by 720 million cubic meters and the decrease of 501 square kilometers of flooding area, which is greatly reduced by the affected orientation and population. If the flood in 1954 occurs, there is no need to enable the flood degradation area around Hongze Lake, which is of great significance to ensure the development of the economic and society of the basin. "Water conservancy project is a basic project for the benefit of the people, and it is also a boutique project that highlights the cultural charm of the Jiangsu water village." Zhang Yazhong said that the second phase of the waterway project will focus on the flood prevention and water supply and other functions. Landscape planning, build boutique water conservancy projects, and promote the integration of water conservancy projects with water resources protection, water ecological construction, and water culture communication.

According to estimates, every 100 billion yuan of major water conservancy projects can drive GDP to increase by 0.15 percentage points and add 490,000 new jobs. The investment in the second phase of the sea waterway is large and the construction period is relatively long, which can play an important role in stable growth and employment. Huai'an, Yancheng and other places will also enter the second phase of the seawater channel project as an important starting point for water conservancy and prosperity, stabilizing investment, stable growth, and promoting development, and better promote high -quality local development.

Zhouqiao Datang Site Park

In Huai'an, the reporter saw that in the Zhouqiao Datang Site Park, Lin Zexu led the crowd to strengthen the stone work wall built by the Hongze Lake embankment, and the "work" -shaped iron pupa inlaid at the connection of stone bricks attracted many tourists to stop; "Thousands of miles "The first gate of Changhuai" — the management office of Sanhe Gate, Qianlong reads that although Hechen Yushi has gone through wind and rain, the handwriting is still there, and the beautiful scenery on both sides of the strait is unspeakable ...

"The second phase of the waterway in the sea waterway is in Jiangsu, and the benefits are in the entire basin. Jiangsu will adhere to the spirit of solidarity and water, adhere to the collaborative governance of the basin, and build the second phase of the seawater channel into a safe waterway in the Huaihe River Basin, the ecological green track of the Jianghuai Plains, and the Su of the Jianghuai Plain, and the Soviet Union of the Jianghuai Plain, and the Soviet Union. The golden channel of Beibei revitalizes. "Chen Jie, director of the Jiangsu Provincial Department of Water Resources, said," After the implementation of the second phase of the Huaihe River, the river channels are wide and the water depth is good, and the depths are appropriate. Class channel navigation requires that it has created conditions for improving the grade of the Huaihe River to the sea and increasing transportation capacity, and it is of great significance to promote the economic and social development along the Huaihe River Basin.
