What is the name of the moat in Linyi?
qinglong river, formerly known as the moat, was built during the Jiajing period of the Ming Dynasty. Qinglong river originates from the Shuitian Bridge in the Su River, leads out from Tongda Road in the Su River, runs through Linyi City from northwest to southeast, and flows into Xiaobudong Irrigation Canal in the southeast of the city, with a total length of 8.46 kilometers and a catchment area of 11 square kilometers. It is an important river channel for rainwater and sewage discharge in Linyi City, and it is also a place for citizens to relax and entertain.
"When I first came to Linyi in the 196s, the Qinglong River was crystal clear, with aquatic plants floating and fish and shrimp infesting; Around the 199s, industrial wastewater and domestic sewage were discharged in large quantities, and the river was yellow and black, dirty and smelly. In the 21st century, qinglong river has completely turned into a stinking backwater. It' s sad to watch! " Zhang Zhongsheng, a CPPCC member from Zhejiang, said this. In 22, during the "two sessions" of the city, he submitted a proposal on the renovation of qinglong river with detailed investigation, concrete measures and sincere words, and was named the No.1 proposal of that year.
Du Jiaju, 74, and Wang Zongyi, 76, from Xinzhuang Lane, Yanchi Street, lanshan district, have lived by the Qinglong River for generations. They have a deep historical memory of the Qinglong River changing from clear to turbid. "Before liberation, qinglong river was separated from the city wall. In the past, it had to pass through the south gate. On both sides of the river, there were long slopes with crops. From before liberation until the 196s and 197s, residents nearby went to the river to fetch water to eat-the water came from the Su River and was sweeter than the water in yi river. Also wash clothes, fish and touch shrimp by the river; Take a bath in the river at night in summer. At that time, the river was wider than it is now. The narrowest part of the water was six or seven meters, and it was fifteen or sixteen meters wide near Dongfanghong Cinema. Qinglong river has changed since 198. Houses have been built along the walls of the old city by the river. With a large population and running water, garbage is dumped into the river casually, and no one manages it. In addition, the water in the Su River is polluted, and qinglong river has also become a stinking ditch. There is nothing else to live here, but there are many mosquitoes and the smell is big! "
In the Feasibility Study Report on Comprehensive Improvement of the Water Environment of Qinglong River, it is written that more than 95% of qinglong river is sewage in the dry season, with serious water pollution and poor environmental sanitation, which affects the city's safe flood season and people's physical and mental health. There are many water-blocking structures in the river channel, the riverbed is heavily silted, the riverbank is thin, the buildings on both sides are messy, the river landscape is gloomy and messy, and the infrastructure on both sides of the river bank is not matched, which is extremely uncoordinated with the development of the whole city and the city appearance.
"From 198s to 26, the government had treated qinglong river three or four times, but it didn't fundamentally change the dirty river and messy environment." Lu Laisheng, chief of the Municipal Administration Section of the Municipal Construction Bureau, said.
It is very urgent to comprehensively renovate qinglong river, comprehensively renovate the river water environment, restore the natural features of the ancient city, and create an excellent living environment.
intercepting pollution and removing silt to clear a river
In p>26, the Linyi Municipal Party Committee and the Municipal Government included the qinglong river control project in key projects. After many investigations, it was finally determined that the whole line of qinglong river should be widened and dredged according to the drainage standard of once every five years, and sewage interception pipelines should be laid along the river; Landscape construction around the river bank. According to the principle of unified planning, one-time design and phased implementation of the municipal government, the first phase is pollution control, and the second phase is river landscape and greening construction. The estimated investment of the treatment project is 53 million yuan.
on March 8, 26, the first phase project of qinglong river started. The project is divided into four sections from north to south and promoted at the same time, and the construction difficulties of each section are varied. From Suhe Gate to Jiefang Road North is the first bid section of the project. Because the underground river has not been cleaned for a long time, there is a large amount of silt, and animal carcasses can be seen everywhere, which exudes stench and biogas, and people can be smoked down in a few minutes. The construction environment is particularly bad, and it is impossible to set up a working surface along the way, so mechanical vehicles cannot enter. In such an environment, the construction team of Juxian Municipal Engineering Company just shoveled and shouldered, and cleared more than 1, cubic meters of silt and thoroughly cleaned the river.
jiefang road north to jinqueshan road north is the second bid section, and many construction areas are near residential areas. Because of traffic control during the day, transport vehicles cannot enter the construction site, and in order to avoid noise disturbing people, construction cannot be carried out at night. At the same time, because the project spans the whole flood season, it is necessary to ensure that a large number of domestic sewage and industrial wastewater are eliminated in time, and that the city can survive the flood season safely without affecting the construction progress.
The construction team from Ganyu Municipal Architecture and Landscape Corporation of Jiangsu Province adopted the sectional containment and drainage construction method. In order to lay the pipeline, they backfilled more than 12, cubic meters of construction waste. After the pipeline was laid, they transported it away, and the whole line cleared 12, cubic meters of silt.
pipe jacking is the key to the successful completion of the whole treatment project. Jinqueshan Road from the north to the north of Customs Road is the third bid section, which is a concentrated place for residence and transportation. In order not to affect the traffic, the engineers of Linyi Shuntong Municipal Maintenance Co., Ltd. adopted the top hole injection pipe technology and made a little progress by pipe jacking. When encountering other pipelines, all kinds of underground pipe networks are criss-crossed, so they can't continue to top, but can only raise or dig down, or re-pipe jacking, and some sections change the pipe jacking process as many as five or six times.
The pavement 289 meters from the front street of the cemetery to the south courtyard of the Municipal People's Hospital is all rock structures, and it is all hard rock strata after 6 meters of underground excavation. Pipe jacking is used to lay sewage pipes, so it is impossible to construct without blasting. Blasting can neither destroy the road surface nor affect the earthquake prevention of the city. Blasting must be carried out in a small area bit by bit in a space that can only accommodate one person, and then the rocks are carried out bit by bit, and only 2 to 3 centimeters can be advanced a day.
Lu laisheng, chief of the municipal administration department of the municipal construction bureau, said that the first phase of qinglong river's treatment project was started from March 8th to November 1th, with 8.46 kilometers of sewage interception pipelines with a diameter of 1,2 mm, rainwater and sewage were separated, and 211 sewage outlets along the river were introduced into the sewage interception pipelines, and domestic and industrial sewage flowed into the sewage treatment plant through the sewage pipelines laid at the bottom of the river bed. During the rainy season, clean rain flows in Qinglong River. In the dry season, the Chanhe River will be diverted to qinglong river, completely changing the situation of "foul smell in sunny days and sewage in rainy season" in qinglong river, and the scenery of "aquatic plants floating with the water, swimming with fish and fine stones, clearly visible" will be presented to the public again.
Tailor-made cultural landscape belt
According to Lu Laisheng, chief of the municipal administration department of the Municipal Construction Bureau, the second phase of the qinglong river River Regulation Project is to landscape and afforest the river. Fifteen meters of landscape green belts will be built on both sides of qinglong river, and the overall environmental quality of qinglong river will be improved through lighting and hardening construction, making it "a scenic belt with ten miles of clear water river", achieving the effect of "smooth river, clear water, green shore and beautiful scenery", improving the good hydrophilic activity space for residents and tourists, creating a comfortable and pleasant green environment and creating an environmental atmosphere that understands the history, culture and celebrity integrity of Linyi City.
The principles of landscape planning in qinglong river are as follows: zoning planning is implemented to reflect the harmony and unity of urban functional zoning and qinglong river landscape zoning; Through the organic combination of historical background and modern civilization, Linyi city has a long history, profound cultural heritage and modern civilization; Take the river as the axis, plan along the coast, adjust measures to local conditions and guide the situation. Make full use of the existing idle land on both sides of the strait to arrange scenic spots, so as to reduce demolition and save investment; Highlight the characteristics of "water city", and reflect the harmony between humanity and nature.
according to the principle of functional zoning and landscape zoning planning in the overall planning of Linyi city, combined with the planning and site selection of the impoundment project, it is proposed to divide the landscape planning of qinglong river into eight scenic spots, namely, from top to bottom, the bamboo forest is full of greenery, the legacy of the scholar, the mighty Yimeng River, the Yishui River is always flowing, the Shuangque River, the Jintan rest, the lake is full of greenery, and the reeds are swaying and fragrant. The scenic spots are connected by colored brick tunnels, and the trees, flowers and shrubs, perennial flowers and green grass are connected, which makes the two sides of qinglong river become interconnected urban landscape belts, reflecting the "curved, quiet, quiet and deep" landscape artistic conception.
