"The' relocation' of street trees on both sides of Foci Street is only the prelude to the transformation of Dashaping North Exit!"
As soon as I crossed the Chengguan Yellow River Bridge, the rolling traffic and dust in the north of the bridge came into view.
"It's better to have some rain in the old days. At least the dust here won't be so big! Everything looks gray and messy in such good weather! " On June 8, in Caochang Street, resident Shi Aunt told reporters. Indeed, under her house, even if the car drives slowly, it will raise the dust all over the sky. It's even worse after the northbound Asia-Pacific Jiayuan. Most of the old roads were crushed. Looking around, the road is bumpy and dusty, and people and cars seem to walk through the fog.
In Foci Street, the street trees on both sides of the main road have all been "relocated". Wei Jinyong, an old resident, told reporters: "Without street trees, Foci Street looks bare. However, I feel that the transformation of Dashaping North Exit is from scratch, starting from scratch, and it may have to be completely changed! "
"The street trees on both sides of Beifoci Street of the Yellow River Bridge began to move collectively on September 26th, making way for the overall renovation of Dashaping North Gate. At present, the street trees on both sides of the main road of Foci Street have all been cleaned up. " The staff of the Greening Management Office of Lanzhou Garden Bureau told the reporter, "The overall renovation of Foci Street is an important part of the extension and renovation project of the North Gate Road in Lanzhou. Whether the transformation can be carried out smoothly affects the promotion of the whole project. It can be said that the migration of street trees on both sides of Foci Street is only a prelude to the transformation of the northern entrance of Dashaping! "
"When it comes to real construction, even if the construction is half done, the half road that can be passed will be very narrow, and the passing vehicles will be crowded and blocked."
The prelude to the transformation of Dashaping North Gate has already sounded, but just seeing the smooth migration of several street trees, can we judge that the overall transformation of Dashaping North Gate has been triumphant and smooth since then? The answer given by the relevant units responsible for engineering design and construction is: it's not that simple!
In order to successfully transform the northern entrance of Dashaping into a green ecological corridor, it is necessary to cross many hurdles.
"According to the design plan, the Lanzhou Municipal Government will adopt the means of ecological protection to comprehensively carry out the comprehensive improvement project of Dashaping North Exit, and build it into a green ecological corridor integrating transportation, protection, landscape and leisure functions." Experts from Lanzhou Urban Construction Design Institute told the reporter that according to the plan, the urban section of Beikou Road in Dashaping, that is, the Foci Street section, should be consistent with the national road 109 section, and the width of the lanes on both sides should be12m, and the green area should be increased as much as possible in the central separation zone. The road greening of this project is mainly the central separation zone and street trees, so as to achieve scenery in all seasons. In terms of landscape greening, with the theme of "being close to the people, leisure and fitness", three centralized street green spaces have been planned on the north side of Dashagou Bridge, Zuojiawan and Beilongkou, including not only walking trails, but also squares and rich green landscapes. "
From this point of view, the planning and design of Dashaping North Exit is very beautiful. However, what specific difficulties and obstacles may be encountered in the implementation of specific projects?
"The existing road width of Dashaping Beikou Road is narrow. The lane of Foci Street is about16m, and other sections are narrower than here. When it comes to real construction, even if half of the construction is adopted, the accessible half of the road will be very narrow, and the passing vehicles will be crowded and blocked, which is extremely unfavorable for construction! " Zhou Liyong, manager of the related project department of Landa Municipal Group, who is in charge of the construction of Foci Street, expressed his greatest concern to the reporter.
Zhou Liyong also told reporters that they will also set up Caochang Street overpass in Caochang Street, and the width of the overpass will reach 16 meters, which is basically the same as the width of the old road, which means that the whole road is almost occupied. Therefore, engineering construction and road traffic have formed an almost irreconcilable contradiction.
The north entrance of Dashaping, which has not yet started construction, has long been blocked by many traffic bottlenecks.
In fact, the north entrance of Dashaping, which has not yet started construction, has long been blocked by many traffic bottlenecks. Zhao Zhiwei works in Lanzhou Yimin Dongfeng Automobile Sales & Service Company near Beilongkou Expressway. He told reporters: "The north exit of Dashaping should have been rectified long ago! Compared with last year's road conditions, this road is really blocked now! It takes more than 40 minutes to commute every day, and the long wait on the bus is really depressing! "
Wang Hailiang, the driver, frowned at the mention of "Dashaping North Exit" when interviewed by reporters. He sighed and said, "Some roads are boiling and it's too difficult to walk! I was so anxious when I met a car. It often takes an hour or two to delay here! "
The traffic police comrade on duty near Landa Prison confirmed Wang Hailiang's statement. He said, "Every morning around 9: 00 am, around noon 12, and from 6: 00 pm to 7: 00 pm, which belongs to the rush hour, the traffic jam is often very serious! It is also difficult for us to guide. "
Wei Jinhai, deputy head of Hebei Brigade of Lanzhou Traffic Police Detachment, told the reporter: "At present, the road conditions at the north exit of Dashaping are extremely poor, and the road surface collapses from time to time when it rains. The traffic police department had to organize manpower to backfill in time to ensure road traffic. Many traffic police members are almost porters! " Wei Jinhai also complained about the poor quality of some drivers. The more they squeeze, the more they push forward, always blocking the road.
During the reconstruction of Dashaping North Exit, the traffic organization is faced with a dilemma.
The construction of Dashaping North Exit is just around the corner, and relevant departments should also issue corresponding "traffic organization plan" as soon as possible. However, the reporter learned from Haikou in Wei and Jin Dynasties that although the traffic police department, the project owner's representative, the public transport department and the construction unit have coordinated the relevant traffic problems, the corresponding targeted "traffic organization plan" has not been worked out in detail.
The current attitude of Lanzhou traffic police department and engineering construction unit is: it is strongly recommended that Dashaping North exit be "totally closed" and the Beilongkou Expressway exit be blocked, so that vehicles entering Lanzhou from here can bypass Tianshui North Road and enter Lanzhou, so as to better ensure the progress and quality of the project.
This proposal is really good for construction, but how to solve the travel problem of tens of thousands of local residents? Are all the bus lines No.8, No.74, etc. 12 entering the extension area refused to carry?
The answer is naturally no! "The north exit of Dashaping is the traffic artery in the extension area. Usually, the traffic volume is larger than the north exit of Tianshui North Road, and the traffic status is more important. So it is not feasible to completely reject traffic. " Wang Ziyun, the owner representative of Dashaping North Export Reconstruction Project of Lanzhou City Investment Company, told the reporter. Therefore, the traffic organization during the reconstruction of Dashaping North Exit is facing a dilemma.
"According to the previous design scheme, the traffic organization during the construction of Dashaping was also considered in advance. In order to ensure uninterrupted traffic during the construction period, the construction methods of partial closure, half-width construction and intermittent release must be adopted, and some vehicles can be diverted to Liu Zhong Expressway. However, the specific traffic organization plan during the construction period still needs to be coordinated and finalized by relevant departments in the near future. " Wang, head of the bidding office of Lanzhou City Investment Company, said.
Whether the reconstruction of the northern entrance of Dashaping will be postponed due to the demolition problem and break through the original expected construction period is still debatable.
Compared with the reconstruction of Tianshui North Road, Langongping and Donggang to Heping section, the reconstruction project of Dashaping North Exit will also be carried out by combining demolition and construction.
Many people question that this method can be "time-consuming". Once the demolition is stagnant, it will often delay the construction period. In order to speed up the demolition progress, Tianshui North Road had to be demolished by blasting. Whether the reconstruction of Dashaping North Exit will be postponed due to demolition is debatable, and whether it will break through the original expected construction period-it will be completed in May next year.
The extension of urban roads mostly involves house demolition. "The transformation of Dashaping Beikou is a good thing! We have been expecting the government to do this for a long time! However, it is said that the road is widened across the board, so will our house be demolished? How much compensation can you give? " Tang, an old resident of Dashaping Street, is very concerned about road reconstruction and demolition.
As the representative of the owner of the project, Wang Ziyun also thinks that the demolition is a thorny issue. Compared with the demolition of Tianshui North Road and other "three gates", the demolition area of Dashaping North Exit is not small. Because there are many units and residential areas along the way, and the wiring at the north and south ends of the project is 6 kilometers long, it is unknown whether the demolition can be carried out smoothly or what new situations will be faced.
"The reconstruction project of Dashaping North Exit, which is about to be implemented, starts from the north bridge head of Chengguan Yellow River Bridge in the south and ends at Beilongkou Expressway overpass in the north, with a total length of 6 kilometers. The core of this project is the reconstruction of road exits. The whole road can be basically divided into two sections: Foci Street south of Dashaping Bridge and the connecting section of National Highway 109. Foci Street is about 2.25 kilometers long, and the connecting section of the northern expressway is 3.73 kilometers long. Dashaping exit road is widened from 30 meters to 36 meters according to the urban road standard, and it is a two-way six-lane road. After expansion, it can meet the traffic volume for 20 years. " Wang Ziyun said: "The demolition of Dashaping North Exit is less than that of Tianshui North Exit, but the demolition problem should not be underestimated!"
"The renovation and demolition of the north entrance of Dashaping is mainly the dilapidated houses along the line, while the residential buildings with five or six floors are generally not demolished, which can not only reduce the cost, but also promote the construction progress. The sooner you decorate, the better! " He further explained. "The Dashaping exit road is widened by 30-36 meters, and there is no uniform road width construction standard for all sections, just to be flexible when encountering demolition problems."
"The trickier thing comes unexpectedly-the dense communication optical cables along the Dashaping exit are extremely complicated ... it takes a lot of effort to move these pipes."
Because the reconstruction of Dashaping exit is a comprehensive reconstruction project, including not only road extension, but also the reconstruction of Dashagou spillway. Among them, the road part consists of roads, guardrails, rainwater, bridges, culverts, greening, lighting and traffic facilities; Spillway is composed of dredging, revetment and management. Compared with other entrances and exits, it undertakes more and heavier contents.
"In the past, the renovation of ditches in Lanzhou was mainly based on engineering measures, but in this plan, the combination of engineering measures and biological measures was adopted for the first time for Dashagou within the renovation scope, and the renovation measures included dredging, revetment and management. Use engineering measures to clean up garbage, dismantle illegal buildings and build bank protection. At the same time, adopt ecological protection to create a green corridor with protection, landscape and leisure functions, and transform the natural ecological environment along the waterway. " The relevant person in charge of Lanzhou City Investment Company introduced.
This is how a beautiful blueprint is woven, but the process of realization requires more sweat.
"With the widening of the exit road and the overall management of Dashagou Spillway, the trickier thing comes unexpectedly-the dense communication optical cable along Dashaping exit is extremely complicated. This dense "big network" includes the provincial communication and transmission bureau, the communication terminal of Lanzhou Military Region, the provincial radio, film and television administration, Lanzhou Radio and Television and other departments, as well as mobile, China Unicom, telecommunications, Netcom and other related communication facilities. In addition, there are water supply and natural gas pipelines running through the whole line. The biggest concern comes from Lanzhou Power Supply Company 10 kV power supply line, which is located on both sides of the 6 km road at Dashaping exit. It takes a lot of effort to move these lines, so be careful! " An engineering technician told reporters without any worries.
With regard to traffic organization, citizens' travel, house demolition and pipeline relocation, we can see that the "north entrance" of Dashaping has to cross several hurdles before it can become a "green corridor", and the hardships are self-evident. To end with a quote from Wang Ziyun: "All difficulties are temporary. After the completion, Lanzhou citizens will see a different big shaping exit: wide road, easy to walk; It is brighter, more beautiful and in a better mood ... At that time, the sacrifice and all the hard work at this moment will show the great significance that has been paid! "
