China Construction Seventh Bureau and Two Company: Guarding the "pulse" of the city and doing excellent people's livelihood answers

The national "Fourteenth Five -Year Plan" New Urbanization Implementation Plan pointed out: To promote the construction of new cities and transform the urban development mode is the key. Adhere to the construction of the people's cities, the people's cities as the people, orderly promote the renovation and transformation of the city, strengthen the construction of facilities such as prevention and control of public health, flood prevention and drainage, disaster prevention and reduction, emergency response and other facilities. Humanities cities make cities a space for people's high -quality life.

The China Construction Seventh Bureau actively devoted to the construction of new types of urban construction, and based on the maintenance project of the Kunshan Central Internal Management Network, builds a total industrial chain solution for the city's transportation and maintenance network, and contributes to the people's high -quality living space of the people. Kunshan builds a socialist modern construction county demonstration contribution to "China Construction Power".

Kunshan, on the banks of Yangcheng Lake, and Water Village Ze State, from May to September each year is the flood season with abundant rainfall. Recently, the residents of Kunshan were surprised to find that the streets at the door of the house changed the normal state of accumulating water into a waterlogging. The streets, a clean and beautiful scene.

This new change is precisely the hard work and wisdom of the China Construction Seventh Board and the Second Company project team that has deeply cultivated the Kunshan Rain sewage pipe network in the past year. If the high -rise building constitutes the "muscles and bones" of the city, then the rain and sewage pipe network extending in the underground is the "blood vessel" of the city. The 3475 kilometers of rain and sewage pipelines, the operating surface reaches 24.9%of the total length of the rainwater pipeline of the Kunshan rainwater. This project is the implementation of the three business integrated development concepts of "construction service providers, investment developers, urban construction operators" and the Kunshan Water Affairs Bureau. "Innovative practice.

The ingenuity of the craftsmanship, the people's "heart" to do the heart

On June 30, the heavy rain poured, and a phone ringing sounded rapidly. "Hello, is it the 12345 hotline? The heavy rain blocked the underground pipeline here in Meihua Garden District, and the parking lot was flooded. Please come over and repair it!" After a minute, the rescue team entered the community. "Don't worry! We must do our best to clear the water!" Huang Ying ordered by Huang Ying, the maintenance project manager of the Central Rings of Kunshan, and the four flood control vehicles began to operate at the same time. After one night of fighting, the ground parking lot was finally dried dry. Essence Without the battle, they struggled for three consecutive days and three nights to complete the pipeline dredging of the area, which completely solved the problems that troubled the residents for many years.

For Huang Ying, such an emergency task has become the norm. The project covers a number of key municipal roads and residential communities. Once the pipes are blocked and flooded, it will have a serious impact on citizens' lives. In order to better deal with the pipe network repair problem that the masses responded, the project set up a professional team, responding to hotlines such as people's livelihood 110, 12345 24 hours, and grid -based to build community pipeline repair communication groups. The problem and rush to solve.

"Since the second company is responsible for the rainwater pipes on our side, the complaint rate has significantly reduced a lot," said the person in charge of the embroidery community. As of now, the project team has completed a total of 6296 repair tasks, and has received 10 flags from the local people and communities to win praise from the surrounding people.

Do a project, serve the masses, and the sewage ditch in the past, and it has changed today. With the efforts of the management of the pipe network maintenance project team, the project team practiced social responsibility, carried the responsibility of the central enterprise, and guarded the unblocked urban pipelines with the ingenuity of the craftsman, and ensured the quality of people's livelihood with the spirit of the owner.

Technology as engine, specimen and cure creation "China Construction Plan"

In the dark pipeline, the four -wheeled robots shuttled flexibly. On the display, the 360 ​​-degree panoramic image clearly shows the rainwater pipelines of the underground vertical and horizontal and dense weaving. As the robot is deepened, a damage point appears at the mouth of the pipeline with a diameter of tens of cm. Being accurately positioned.

This is the CCTV pipeline endless TV detection system introduced by the project team. It automatically shuttles through the pipeline through the crawler and returns images such as rust layers, scale corrosion, perforation, cracks in the pipeline. Pipe treatment plan.

"Relying on the project, we successfully set up the only subject of the Ministry of Housing and Construction of Suzhou this year, and carry out the research and development of intelligent inspection robots in drainage pipelines. After the robot has completed the inspection, it will not only conduct a comprehensive diagnosis of pipeline diseases and pipeline efficiency, but also generate simultaneously. Urban Underground Pipe Network BIM model. "Wan Yanjianfei, general manager of the Second Company Enterprise Technology Center, said," The traditional two -dimensional graphics, with the help of the three -dimensional visualization characteristics of BIM technology, can greatly improve the efficiency of work, and for the defects of the existing drainage pipe network Provide support for the assessment of discharge and drainage flood and drainage capacity. "

In the management and maintenance management of the network, the seventh bureaus of China Construction made full use of their technical strength, and cooperated with universities such as Hohai University and Nanjing University to carry out research and development work. At the same time, relying on the industrial forward -looking project of Suzhou City, the research and development of special robots for the integrated operation of drainage pipeline inspections and repair and repair is carried out, and the intelligent inspection of pipelines has been opened to the technical route of non -excavation and repair.

During the emergency repair, the staff of the project department found that with the process of high -speed advancement of urban construction, construction waste and oil congestion replaced common stasis problems such as domestic waste and sediment, and became the "lesion" of pipeline blocking. Traditional high -pressure water -to -water dredging method is too small, often "cure the standards and not the root cause", what should I do? The project department explores "milling cutter+'杼 易 项目' to dredging method", cut the oil dirt and construction waste residue into small pieces through milling cutter, and then use "Yijing Easy Water" Check the well, and finally draw the accumulation to the stain absorption vehicle.

A series of scientific and technological research and technological research on the project team provides strong support for the improvement of quality and efficiency of urban drainage pipe network operations.

Quality is important, deep cultivation of land to fight for industry benchmarks

"When we take root in Kunshan, we must play the responsibility of the central enterprises of the local government and show the style of the 'China -China Iron Army'." Huang Ying said that since the beginning of the project, the project team has set a goal to strive for the industry model for Kunshan Pipeline's maintenance.

The rain sewage pipe network is buried deep underground, the radon is filled, the water quality is dirty, and the oxygen is thin. Every underground operation is dangerous. Therefore, the safety of limited space operations has always been the top priority of project work. "In order to maximize the risk of pipeline diving operations, we strictly demanded that the operator holds a certificate and formulates a set of limited space operation specifications. It checks the equipment every day, safety inspections every week, and conduct special training and emergency drills every month." The project. "The project." The project. " Security Director Zhou Jianfeng said.

After nearly a year of quenching and accumulation, the project department formed a sound pipe network maintenance system and operating process, and wrote a standardized "Pipe Network Conservation Construction Safety Operation Manual".

In addition to high standards in safety construction, the project team dares to "be ruthless" in the assessment standards. In the past, the standards of pipeline network maintenance work are different, and the level of maintenance is uneven. The Kunshan pipeline network project first adopts the nationwide use of the "sewage concentration" as an assessment indicator and the annual assessed unit. The water does not enter the tube, and the rain does not enter the factory. "

Leading the party building, the banner orientation, the project department also adheres to the innovation of community grid maintenance management work, the standardization of the "party member responsibility zone", standardization of the CI image display, and standardization of safety protection to ensure that the branch is built on the project. One Pioneer "Demonstration on the first line.

As of now, the project has completed the total of 1046.3 kilometers of rainwater pipelines in Kunshan City, 886.2 kilometers of sewage pipeline maintenance, clearing inspection wells, and rainwater border wells, etc., and 263 and 2.9 kilometers of rainwater pipes.

"Spring is vast, and the city is full of smoke and rain over Kunshan." Now in Kunshan, after the rain, the grass color is as new and the streets are new, and a happy and harmonious happy picture of livable and livable, beautiful and harmonious is unfolding. (Correspondent Xiao Ao, Wang Li Lei)
