Two large asphalt pavers walked side by side, and the road roller followed them to roll. The brand-new asphalt pavement continued to extend in front of us... Yesterday morning, at the construction site of Tianshan Road Reconstruction and Upgrading Project in Yantai Huangbohai New Area, the reporter saw that the last section of the road was being paved with asphalt, and the motorway was temporarily open to traffic.

In April this year, the road upgrading and reconstruction project of Tianshan Road started. At the beginning of the planning and design, Tianshan Road was positioned as an innovative and demonstrative "coastal city style avenue" to meet the future needs of the city. While meeting the pipeline carrying capacity and road traffic efficiency, it broke through the traditional road design approach, adopted the design approach of "three lines integration", and changed the design scope from red and green to red, green Integrated design of three lines of building retreat. Replace the original green belt from the outside of the road red line to the inside of the red line for redistribution, and set green belt between the motorway, non motorway and sidewalk. Optimize sections, reasonably and innovatively arrange pedestrian space, car space and street space, and pay more attention to pedestrian experience.

Visiting the reconstructed Tianshan Road, the reporter felt the thick "temperature" of people's livelihood in full details.

Overcoming Difficulties: Tianshan Road Makes a New Appearance

At 10 a.m., the reporter came to the construction site at the intersection of Tianshan Road and Yongjiang Road. The asphalt heat wave came, and the construction scene in full swing attracted many people to watch.

Two large asphalt pavers move forward side by side. The asphalt is evenly spread on the pavement, and the roller rolls back and forth. The new asphalt pavement continues to extend.

"Two 7.5m pavers are used for online paving, and the non-contact balance beam method is used for paving to maximize the road flatness. When paving asphalt in the widened section, one retractable paver and two 7.5m pavers are used for paving. The widened section is paved first, followed by the normal section, and paved in echelon." Han Xiangzhu, Construction and Transportation Bureau of Huanghai Bohai New Area, told the reporter that during the asphalt paving process, a specially assigned person was responsible for the flatness inspection, strictly controlling the height difference, and ensuring the smooth driving of vehicles.

"All engineering materials are strictly controlled, and all processes are kept improving." Han Xiangzhu introduced that, for example, in the material control of curbs and sidewalks, special personnel were assigned to control the processing quality and progress, and the processing accuracy, color difference and appearance quality were strictly controlled. The arc section materials were typeset in advance, and all the numbers were customized to ensure the overall line shape was smooth and natural. During the control of asphalt raw materials, experienced quality inspection personnel shall be assigned to watch the site, and the mix proportion shall be adjusted in time according to the on-site paving conditions. The person in charge of the supervision unit, Wang Jianrong, also made a round trip inspection on the site. They closely followed each operation procedure, and the key procedures and parts were monitored 24 hours on site to ensure the quality and safety of the project through the combination of daily inspection and parallel inspection.

The reconstruction and upgrading project of Tianshan Road was started in April this year. In half a year, we overcame difficulties along the way, both external factors such as the impact of the epidemic on construction materials and personnel, and technical difficulties. "The underground soil of the project is complex, most of which are silty fine sand and muddy silty soil, and the bearing capacity of the foundation cannot meet the design requirements." Han Xiangzhu introduced that, in order to ensure the overall construction quality, Tianshan Road Express Lane is designed to be filled with graded crushed stones. Parts with poor soil quality are comprehensively cleaned and replaced to eliminate any hidden danger that may cause uneven settlement of the road; During the backfilling of planting soil for greening, soil source screening and soil sample testing shall be carried out in advance, and miscellaneous fill in the planting area shall be removed to undisturbed soil. Each point shall be numbered for acceptance, and the quality and depth of planting soil shall be strictly controlled to ensure the growth of greening seedlings in the later period. In addition, groundwater treatment is also a major difficulty in the deep foundation pit project of the project. The project adopts steel sheet pile support for dewatering in the pit and the method of reinjection outside the pit to ensure that there is no water in the foundation pit, and at the same time, the impact of dewatering and drainage of groundwater on surrounding buildings is minimized.

"At the construction site of Tianshan Road, 45 large construction machines were put in, and more than 600 construction workers were employed. The staff of the participating units gave up the holidays and worked overtime, especially for the construction sections with night operation conditions. They worked 24 hours a day." Han Xiangzhu said that many new technologies have also been applied in the construction, such as the construction of the main structure of the power tunnel using the skip warehouse method, which not only ensures the quality, but also improves the efficiency.

After a half year's absence, Tianshan Road reappeared in front of the citizens, and the sense of happiness came into being.

Full of details to highlight the "temperature" of people's livelihood

The reconstruction of Tianshan Road is not only a renewal of the road, but also an improvement of the city's "temperature".

The total length of the reconstruction and upgrading project is 4.2 kilometers. The width of the red line from the auxiliary road of Shenyang Haikou Expressway to Jialingjiang Road and from Huanghe Road to Haibin Road is 38 meters. After the reconstruction, the width of the red line from Jialingjiang Road to Huanghe Road is 60 meters. After the reconstruction, the width of the red line from the auxiliary road of Shenyang Haikou Expressway to Jialingjiang Road and Huanghe Road to Haibin Road is eight lanes in both directions, making driving more smooth.

The reporter saw that there are green belts between motorways, non motorways and sidewalks for isolation. People and vehicles go their own ways, broaden the turning space of vehicles, provide safety island space for pedestrians, and greatly improve the safety of traffic. The central separator is also a green belt. Different sections of the road are mainly characterized by flowering or colored leaves, with flowering shrubs and evergreen plants, to create a rhythmic sense of ups and downs, density and order.

After the reconstruction of Tianshan Road, a total of 7 groups of 14 bus stops will be set up. Except for the straight bus stop on the side of Aihua Bilingual School due to the limitation of terrain elevation difference, other bus stops will be harbor bus stops. Tianshan Road is an important connecting link in the north-south direction. There are many intersections. The intersection has been channelized during the reconstruction, so the vehicle traffic efficiency is higher.

On the south side of the Second Junior Middle School, the main body of an underground street crossing has been completed and is preparing for decoration. After the passage is completed, parents and students can pass through the underground passage, avoiding the congestion caused by pedestrians crossing the street. In front of Aihua Bilingual School, two temporary parking spaces are reserved to pick up students, so as to avoid road congestion during school and after school, and also provide safe travel space for students and parents.

"Tianshan Road is the only way for me to go to work. Now it is very smooth to drive, and it is safe to walk and ride a bike. Every detail brings great convenience to the citizens. Looking at such a beautiful road, I feel better about commuting." During the interview, Xu Liang, a citizen living nearby, constantly praised the new Tianshan Road.

One scene along the way makes the city full of vitality

"Transforming a road and creating a landscape belt", the landscape improvement project of Tianshan Road is highly anticipated. At present, the pavement of Tianshan Road is under final construction. In the next step, the construction of slow lanes, sidewalks, street lamps, bus stops and street trees will be carried out successively, and the construction within the red line will be completed by the end of the year. "After the main road is opened, marking, signal light installation, slow lane and sidewalk construction will be carried out in succession. Please follow the signs and pay attention to traffic safety." Han Xiangzhu said.

The reporter learned that the rebuilt Tianshan Road has added a central green belt and a side belt, enriching the landscape level along the road, forming the effect of flowers in three seasons, evergreen in four seasons, and colorful, so that citizens can enjoy the convenient transportation and enjoy the beautiful scenery at the same time.

Han Xiangzhu told the reporter that Tianshan Road has custom-made "Yulan" lanterns and "Molan" bus stop pavilions. The design of natural undulating rhythm is adopted for the greening of the central divider. The street tree is North American red oak for the first time. The tree is full in shape, which can achieve good shade effect after planting. The red leaf period in autumn is longer, forming a colorful landscape avenue.

In addition, seven pocket parks will be built along Tianshan Road. In combination with the Second Junior High School and Yaohua School, two landscape nodes will be built, and public toilets and slow traffic systems will be reasonably set up. A green, low-carbon, comfortable, slow traffic, intelligent and dynamic coastal city style avenue is ready to emerge.

Since this year, the Huanghai Bohai New Area has continued to make efforts in four aspects: trunk road network, roads in key areas, access to cut off roads, and road quality improvement and upgrading. Throughout the year, 27 road projects, including Tianshan Road Reconstruction Project, S304 Reconstruction Project, and Shanghai Street West Extension Project, have been implemented, with a total length of 121 kilometers, to comprehensively improve regional accessibility and urban level.

In recent years, the Yellow Sea and Bohai New Area has focused on the leap forward improvement of urban function, image and quality, with the vision and goal of building a high-quality urban demonstration area, adhered to the positioning of high points, advanced planning, and focused on the construction of traffic road network. According to the overall idea of "improving the quality and upgrading of the east area, and improving the connectivity of the west area", the accumulated investment is about 3.135 billion yuan, and the system has implemented the Yellow River Road, Pearl River Road, Jinshajiang Road, Taishan Road Fourteen old roads in the east area, including Huangshan Road, have been reconstructed, with a total length of about 43.1 km. The opening of 36 western roads such as the West Extension of Shanghai Avenue and Haibin Road provides supporting support for key areas such as the Cishan International Scientific Research Corridor and Bajiaowan Central Innovation Zone. In order to improve the citizens' satisfaction, sense of gain and sense of happiness in urban construction, efforts are made to promote the optimization of the road network structure, open up the dead end roads and T-shaped roads such as Guiyang Street, Yangzhou Street, Nanchang Street, Shantou Street, etc., orderly open up the dead end of urban traffic, further supplement the traffic weaknesses, improve the road traffic capacity, and smooth the urban microcirculation.

The new Tianshan Road has regained its busyness. Looking at the Yellow Sea and Bohai Sea New Area, the roads shuttling between cities are like "blood vessels", making the city full of vitality and vitality, and making life vigorous and poetic. With the promotion of reconstruction of Tianshan Road, the road network has become more smooth, the scenery has become more beautiful, and the "pulse" of the development of the New Area has become more powerful.
