Xiahe in late autumn is colorful. On the golden grassland, cattle and sheep are leisurely grazing, the green Daxia River flows slowly, and under the blue sky and white clouds, accompanied by the roar of rumble and joyful singing, a brand-new high-speed traverses the mountains and rivers, like a giant dragon moving forward. extend. This expressway is the Wangxia Expressway that is about to open to traffic.
S38 line Wanggertang to Xiahe (Sangke) expressway project is one of the contact lines planned in the "Gansu Provincial Road Network Planning (2013-2030)", and it is an important target section for realizing the expressway between counties and counties in our province. It is also a key construction project determined by the provincial party committee and the provincial government in 2018. The construction of this project can make it easier and faster for domestic and foreign tourists to enter the famous scenic spots such as Labrang Monastery and Sangke Grassland in Xiahe County, and can connect its rich tourism resources with the surrounding tourism resources through the Linhe Expressway. , The construction of the project is of great significance to the development of tourism resources, driving regional economic development, promoting national unity and poverty alleviation and development.
In order to make this road open to traffic as soon as possible, all the participating units set their goals ahead, shoulder their responsibilities, engrave their mission in their hearts, use the natural moat to turn the road into a smooth road, and build the heroic momentum of the road. A strong song of fighting the heavens and the earth, Gansu Road and Bridge is a strong team among the participants.
The first standard project of Wangxia Pavement constructed by Gansu Road and Bridge, with a total length of 41.595 kilometers, starts at Wangtang Village, Wanggertang Town, Xiahe County, and ends at Sangke Village, Sangke Township. The whole line adopts the standard construction of two-way four-lane expressway, with a design speed of 80 km/h.
Since the start of construction, the project department has strictly implemented the decision-making, deployment and work requirements of the Provincial Department of Transportation, Provincial Public Transport Construction Group and Gansu Road and Bridge Group Corporation, with " quality engineering" as the starting point, and striving for model projects as the goal , pay close attention to the refined management of pavement construction, urge the improvement of quality and efficiency of construction projects, advance planning, and strictly control the process, which has been repeatedly praised by higher-level units.
Innovation is the soul, creating quality engineering
Science and technology is an important means to improve project quality and speed up construction progress, and it is also an effective measure to improve project quality and efficiency. In recent years, relying on the projects under construction, Gansu Road and Bridge has focused on the "four new" technologies, and has carried out extensive employee innovation activities, taking technical competitions and technological achievements into project activities as carriers, adapting measures to local conditions, highlighting characteristics, exploring and cultivating innovative talents, creating Everyone cares about, supports and participates in the cultural atmosphere of innovation, efficiency and independent innovation, and transmits the positive energy of innovation. Fruitful results have been achieved in the compilation of construction methods, declaration of scientific and technological achievements, patents for inventions, and technological innovation.
Wang Xia Road No. 1 actively responded to the call, combined with the actual production of the project, relying on the project construction, while applying mature new technologies on a regular basis, vigorously carried out technological innovation, took youth innovation and innovation activities as the focus of work, and actively guided the majority of young workers Write a new chapter with youth and wisdom.
At present, 3 technical innovations have obtained the utility model patent certificate of the State Intellectual Property Office. At the same time, the project also took the initiative to undertake two "QC" group projects, declared three construction methods and two scientific research projects.
Fighting the sky and running out of "road and bridge speed"In April and May, the effective construction period was short, which put a lot of pressure on the project department. In 2021, when receiving the progress target responsibility letter issued by the project office, all the staff of the project department felt pressured. Due to various factors such as weather, epidemic and cross-construction, the subgrade was only 1.3 kilometers away for inspection. At the same time, pavement engineering construction is most afraid of not being able to operate continuously on a large area. The disassembly, transfer and installation of large-scale machinery and equipment is a time-consuming and laborious process. Too many surface joints will also affect the smoothness of the pavement. The working surface is discontinuous and repeated. The transfer operation has become the biggest problem faced by the construction workers.
In the face of many difficulties such as tight construction schedule, delayed roadbed inspection, discontinuous working face, etc., the project department adheres to the tenet of "inspecting a section and paving a section", and will not wait and rely on during the construction. Check with the roadbed unit. At the same time, progress correction measures are formulated for each construction department, timely correction and adjustment are made according to the actual construction situation, and the incentive and punishment mechanism is used to enhance the initiative and enthusiasm of all construction personnel. The person-in-charge is in charge of different sections, and the construction tasks of each construction department are coordinated and arranged by the person in charge, and the deviation of the process is reported on the spot, and the daily work deployment and the work summary of the day are done well. Various functional departments and construction offices cooperated highly, integrated various interference factors in the construction process, foreseen in advance, corrected in time, caught up with the schedule within the effective time, raced against time, set off a big upsurge in adversity, reversed the passive situation, ensured The smooth progress of the project construction.
At 0:00 on January 1, 2022, the Wanggertang to Xiahe section (21.44km) of the Wang-Xia Expressway of Line S38 was officially opened to traffic, marking the successful conclusion of the first phase of the project.
In 2022, due to the heavy rain and snow and the impact of the epidemic, personnel were not allowed to enter the site until mid-April. Since the official resumption of work and production on May 5, the project department has taken multiple measures to overcome the adverse effects of the epidemic and Various difficulties such as tight supply of asphalt materials. Faced with the tight schedule and heavy tasks, the project department quickly adjusted its thinking, formulated a strict construction schedule, and firmly grasped the golden season and favorable opportunity of road construction, took multiple measures to fight the "combination punch", and gave full play to the situation. The party branch of the project plays the role of a battle fortress, the party building and project construction are effectively integrated, new equipment is introduced, and various road machinery and equipment and personnel are provided in a timely manner. "Double insurance", all the construction staff "twisted into a single rope", with wisdom and sweat to advance tenaciously, high quality and high efficiency to promote the smooth completion of the remaining projects.
At 6:00 pm on September 23, 2022, the asphalt surface of the entire line was successfully closed, marking the smooth closure of the asphalt surface of the entire Wangxia Expressway, and the opening to traffic is just around the corner.
It is worth mentioning that the Labrang super-long tunnel is one of the controlled projects of the Wangxia Expressway , with a total length of 5.5 kilometers. Before the tunnel was built, the project department formulated a detailed special construction plan, made great efforts to clean the tunnel pavement, and introduced the dry and wet dual-purpose sweeper , which overcomes many difficulties and drawbacks in the construction of a relatively closed tunnel. Speed up the construction progress. At the same time, the project leadership team is on duty, paying close attention to the smoothness of the asphalt surface and the compaction degree. The technicians and operators work overtime and work closely with the functional departments and labor service teams. With the attitude of a 100-meter sprint, he made every effort to seize the progress of the project.
Fine management to promote quality and efficiency
Project quality is the life of a construction enterprise and the cornerstone of the market. The project department has established and improved the quality management system, formulated the project quality management system and methods, and realized the quality management of all employees, all-round and whole process, and the quality of the project is always under control. Strictly control the entry of materials, implement weighing of vehicles and special personnel, especially for gravel, asphalt, etc., and strictly implement GPS full-process monitoring and one-vehicle inspection system to ensure that qualified materials are used in engineering construction; starting from the laboratory, carefully Design and optimize the mix ratio to ensure that the produced mixture meets the design requirements; strengthen the construction site management, communicate and coordinate with technical personnel in a timely manner, and track the construction process and various indicators throughout the process; hold regular monthly quality analysis meetings to review the existing quality Analyze problems and formulate solutions to ensure early detection and early resolution of problems;Detail management. From the sub-base to the surface layer, all support formwork and end formwork are added during paving at the construction site, which not only ensures the line shape and edge compaction, but also reduces the waste of raw materials caused by edge cutting, and achieves a real sense of Reduce costs and increase efficiency; strengthen quality supervision. The project department has perfected the construction of the quality self-inspection system. By increasing the inspection of physical projects, issuing quality rectification notices, and establishing a notification system for substandard products, the project department speaks with data and pictures, dares to expose ugliness, is good at improvement, and uses the supervision system. The construction ensures the quality of the project; strengthens the training of technicians, makes use of the free time at night to familiarize the technicians with the design drawings and technical specifications through training, conduct standardized construction in strict accordance with the requirements of the design drawings and specifications, and actively build a brand of pavement construction; promote the " smart construction site" ” construction to improve the level of project management informatization. Applying " Internet + ", through the real-time automatic collection, upload and analysis of the data connected to the mixing station production and site laboratory monitoring systems, real-time monitoring and early warning of the production quality.
Security is the lifeblood of engineering. The project department strictly implements General Secretary Xi Jinping's life-oriented management philosophy that "development must never be at the expense of human life", adhering to the policy of "safety first, prevention first, comprehensive management", with "responsibility at all levels, everyone Based on the safety production responsibility system of "being responsible and responsible for their own responsibilities", with safety education and training and safety inspection of all employees as the starting point, the normalization of project safety management is promoted.
Mechanical injury is a major source of danger in pavement construction projects. The project attaches great importance to the installation and use of safety warning devices for mechanical equipment and transportation vehicles, and regularly checks the integrity of the equipment to ensure the normal use of the equipment, so as to do the basic work for building intrinsic safety. All equipment of the project department, including leased machinery and equipment, are required to be installed with reversing radar and reversing video; all mixing stations are installed with interlocking power-off devices; all road rollers are installed with anti-collision guardrails , and at the same time, they have independently innovated the warning of the roller operation area. The device greatly improves the safety factor of the ground auxiliary operators when the equipment is operating at night, and effectively ensures the safety of driving and the safety of road operators.
Under constant efforts, the project department won the honorary title of "Provincial Demonstration Contract Section of Highway Engineering Safe Site Construction" by the Provincial Department of Transportation in 2020 and 2021.
