Li Guoqiang, Chief Engineer of the Pengqi Project Department of China Railway 14th Bureau Group. He has successively participated in the construction of the first and second phases of the Lanyan Railway, Xining Ring Expressway, Qinghai Atong Highway Project, Henan Xinyang Expressway, Chengdu-Mianyang-Leshan High-speed Railway Project, and Yantai Port-dredging Expressway, and has held positions such as technician, technical director, and chief engineer. Regardless of the position, Comrade Li Guoqiang has always been extremely responsible for his work, advancing despite difficulties and meeting challenges head-on with a spirit of responsibility for work and technology, excellently completing various tasks, and writing the most beautiful railway construction dream in his hard work. Since 2000, he has been rated by the company as "Advanced Worker", "Six-Good Communist Party Member", and by the group company as "Meritorious Service Award" and "Three Civilizations" Construction Advanced Individual.

Leading by Example, He Is the Flying Goose at the Forefront

For more than 10 years, in response to the reality that the vast majority of technical personnel in the branch are trainees and interns, Li Guoqiang has adopted various forms to teach by personal example. Whether in the office, dormitory, or at the construction site, he often takes time and energy to teach young technical personnel by word and deed. Ideologically, he encourages them to establish a spirit of dedication and hard work based on their positions, and to quickly get rid of the "habit of valuing immediate interests and tangible benefits while neglecting ideological cultivation." In work, he requires that drawing reviews be meticulous, calculation data be careful and accurate, and no link be overlooked. In on-site measurement, repeated investigation and transcription verification are required to strive for perfection. He particularly requires them to continuously learn and enrich their experience during construction, improve their technical level, and constantly adapt to high-standard construction needs. In life, he cares deeply for young technical personnel, keeping everyone ideologically stable and hardworking. Especially for newly assigned students, he promptly arranges experienced technical personnel for "mentor-apprentice" activities, making new students feel that there is something to learn and their professional skills improve quickly. He himself was awarded the company's 2011 "Excellent Mentor" title. Through training, most technical personnel have grown rapidly and been assigned to various work points. Among them, the 5 technicians he led have now become technical supervisors in other projects and can handle matters independently. The engineering quality they are responsible for has been well received by provincial leaders and the owner, providing sufficient technical strength for the company's long-term development. On the other hand, he infects young employees with his practical actions and exemplary role. From the first day he arrived at the project department, he stepped into his role. During the day, he rushed around the construction site with technical personnel for line re-survey and emergency repair of access roads, sweating in sunny weather and covered in mud in rainy weather. At night, he reviewed drawings and designed construction organization plans in the office until the early morning, drinking a glass of water when thirsty and eating a pack of instant noodles when hungry. During one emergency repair of an access road, he took the lead, braving severe cold and persisting in commanding at the front line until the access road was repaired at 4 a.m., only then returning to the manager's office to rest, and he was back at work in the office on time in the morning.

Strictly Controlling Quality and Safety, He Is the Frontline "Black-Faced Judge"

When Li Guoqiang served as Chief Engineer of the Yantai Port-dredging Expressway Project, the bridge and culvert and earthwork quantities were large, and most bridges were cast-in-place prestressed box girders. The project department's technicians were basically newly graduated students who did not understand the full-scaffold method at all. He promptly organized all technical personnel to study the construction technology of cast-in-place box girders using the full-scaffold method and prestressing construction technology, greatly improving the technicians' understanding of construction methods and safety and quality control for cast-in-place box girders, laying the foundation for subsequent box girder construction. He promptly formulated a scientific and reasonable construction plan "Construction Technology and Safety Protection Control Method for Full-Scaffold Support Erection for Cross-Line Cast-in-Place Box Girders" as required by the owner, which passed expert demonstration in one go, pointing out the direction for subsequent construction and receiving unanimous praise from experts and the owner.

Before the construction of each process, corresponding technical disclosures and safety disclosures are formulated to avoid rework. For all key part projects, the "first-piece project" approval system is unconditionally implemented. This work has been unanimously recognized by the owner and supervisor.

The Longgang South Interchange is a key, highlight, and difficult project of this engineering project. He personally took charge of the construction of this interchange, strictly controlling the internal and appearance quality of the project. It achieved high evaluations in the monthly assessments organized by the owner and in successive inspections by the provincial quality supervision station. The interchange has been reported to the company to apply for the provincial quality cup project.

In work, he personally supervised and guided each first-piece project and test section construction from beginning to end, standing on site for several hours and eating at the construction site. Most touching was that in October, during the paving construction of the water-stabilized crushed stone base test section, his 7-year-old son fell at school and hit his head against a wall, causing intracranial bleeding. The doctor required hospitalization, and only his wife was at home to care for the child. Upon hearing this, project department leaders told him to go home immediately to see his child. However, because at that time all technicians were very unfamiliar with the paving construction of the road surface water-stabilized crushed stone base, he insisted on waiting until the test section was successfully paved before going home to see his child.

Doing a good job in change work and striving to reduce losses and increase efficiency for the project. Due to various reasons, this project was a loss-making project after company accounting in the early stage of mobilization. In work, he actively cooperated with the project manager on project changes, strengthened communication with the supervisor and owner, and often traveled alone among the design institute, owner, supervisor, and audit departments. After multiple negotiations and unremitting efforts by the project department, changes were finally agreed upon for the two major items of material price adjustment and the addition of Nanshan Avenue. These two items alone reduced the project department's losses by more than 20 million yuan.

United and Forging Ahead, He Is the Team's "Backbone"

In the project's technical management work, he particularly emphasizes team spirit, division of labor, and opposes individualism. He often says that the project we form is like a big family, where everyone has their own position and role. One should not overly focus on oneself but also should not belittle oneself. All technical personnel in the project department are representatives of the entire project's technical work. Everyone is a member of this big family, and everyone should contribute their own strength to the harmony and stability of this big family. Therefore, establishing a united and harmonious project management team is particularly important; this is the overall situation. He often says: "Technical team members should communicate frequently, build relationships, and integrate advantages. Only in this way can the overall function be maximized, and only then can we have the best talent team to serve our project construction. This is the prerequisite for working together in unity." In more than two years as chief engineer, he has always maintained a high sense of responsibility and strong dedication to his career. In construction management, he continuously pioneers and innovates, adheres to technological innovation, resolutely implements the enterprise guiding ideology of "safety first, quality first," and vigorously implements it.

"Love whatever you do; as long as you are engaged in this work, you must do it well." This is his motto. Although it is a very concise sentence, he has proven his serious and responsible attitude toward work through practical actions. In work, he is amiable and kind, especially to young technical personnel, patiently helping them solve technical problems, helping them set the main direction of technical attack, pointing out their shortcomings, and planning their future development path. He cares for and cherishes comrades, treats everyone equally, and is broad-minded. In life, due to the nature of work, he rarely goes home. Although he misses his family far away very much, as the person responsible for technical quality along the entire line, he knows how much responsibility and mission he shoulders. He handles all matters, big and small, at the construction site one by one, fearing any slight mistake. He has no complaints or regrets about his work. For the early completion of the project, he is willing to be a paving stone, practicing the mission of a road builder with practical actions.

The new era presents many challenges to everyone. Only by continuously learning to improve oneself can one better meet the requirements of the times. Every time he arrives at a project department, he encounters many new technical problems. No matter how busy work is, he will take time to study monographs and papers on high-speed railway construction, thereby quickly mastering many advanced construction technologies and applying them to the construction site, overcoming many technical difficulties and contributing his strength to China Railway's road construction. At the same time, he also actively participates in the construction technology paper writing organized by the company. His 2011 paper "Construction Technology and Safety Protection Control Method for Full-Scaffold Support Erection of Cast-in-Place Box Girders on the Main Line Bridge of Longgang South Interchange Crossing Rongwu Expressway" won the company's first prize for excellent papers and the group company's second prize for excellent papers.

Technological Innovation, He Is the Most Beautiful "Environmental Protector"

Green construction is an important way for construction enterprises to achieve transformation of development mode and an important means to improve comprehensive benefits. In the Pengqi Project Department, the green construction technology innovation team led by Li Guoqiang has implanted such a definition from concept to practice.

Green planning is synchronized with the preparation of construction plans. At the beginning of the project, he treated environmental protection together with construction safety, quality, schedule, and benefits as important project indicators, and formulated regulations, specific measures, and reward and punishment methods. In the early stage of the project, a green construction implementation plan was prepared, and multiple energy-saving and environmental protection measures were established, starting from environmental protection, material saving and material resource utilization, water saving and water resource utilization, energy saving and energy utilization, and land saving and land resource utilization, providing institutional guarantees for green construction.

Since the start of construction, Li Guoqiang, according to the green construction requirements of each construction stage and combined with local resource and environmental characteristics, invited environmental protection experts and, together with the innovation team, analyzed the environmental factors of resource, energy (water, electricity, oil), and main building material consumption, and optimized the construction plan. During construction, he fully improved the turnover utilization rate of equipment and materials, applied energy-saving and water-saving products and used new equipment and new processes, and continuously improved green construction hardware measures for energy saving, water saving, material saving, and land saving. From establishing organizational structures to determining goals, formulating plans, implementing control, and comparative analysis, he improved the full-link guarantee system extending vertically to the bottom and horizontally to the edges, integrating "four savings and one environmental protection" throughout the entire process of construction, office, and life.

The site implements intensive management and factory production, achieving centralized mixing of concrete, centralized processing of steel bars, centralized prefabrication of concrete components, and fully enclosed production of material silos. The concrete mixing station at the production base is located on the local main traffic road and in an orchard. During production, to control dust and sewage discharge, each cement tank at the mixing station is equipped with dust removal equipment, and a four-stage sewage sedimentation tank is set up. After four-stage sedimentation, wastewater is recycled for daily washing of transport vehicles and pumping equipment, saving a large amount of water and achieving the goals of recyclable production wastewater and zero sewage discharge.

The heavy transport vehicles required for construction shuttle daily between the main traffic road and the site. In sunny weather, they raise dust, which will harm fruit trees and crops along the route, while in rainy weather, they easily cause mud leakage and spillage, polluting access roads and the station. Therefore, the project department strictly sets the transport routes for engineering vehicles, and sprinkler trucks sprinkle water on access roads and the highways passed at any time. A specially made collection bucket is hung at the rear of each tank truck, which can reduce concrete loss and also avoid pollution of existing roads and construction access road surfaces by concrete dropped during transportation. Full-time environmental protection supervisors conduct irregular inspections and supervision of transport vehicles, stopping arbitrary slag dumping and tank truck cleaning.

Optimize the construction plan and rationally allocate earthwork. Combined with the longitudinal slope of the area passed by the route, ensure one-time qualification and rational allocation of earthwork. In earthwork allocation, clearly define reasonable transport distances and select borrow and spoil ground locations, better controlling transport routes, avoiding long-distance vehicle transport, and reducing energy consumption. In land acquisition, the project department adheres to economical and intensive use. According to land, environmental, water, and soil conservation requirements, temporary land already used is reclaimed, greened, enclosed, and river channels are dredged and cleaned. In foundation excavation construction, waste mud generated by impact drills is recycled after treatment, saving bentonite. Cleared surface humus soil is centrally stacked for grass planting on roadbed slopes, and soil settled in mud pits is dried and used as planting soil. A large amount of mud generated by pile foundation construction is centrally treated. Special mud trucks extract the mud and store it centrally in large mud pits in the interchange area. After a period of sedimentation, the surface mud water can be pumped out with sewage pumps for recycling in impact drilling pile driving.

To reduce the harm of construction noise to surrounding residents, sound source control is set up from various construction machinery and small tools. During construction, environmental protection inspectors are assigned to check mechanical equipment that generates relatively large noise, promptly maintain and service them, and promptly tighten or replace loose or worn parts so that mechanical equipment remains in good operating condition. At the same time, during the construction of structures, the location of the concrete pump truck is determined and arranged in an open area away from existing roads. When operating near villagers' residences, soundproof sheds are set up around the pump, and rotating device protective covers are installed to reduce noise disturbance to residents.

After more than a year of unremitting efforts, the Pengqi Expressway construction project of the 14th Bureau won the title of the fifth batch of "National Construction Industry Green Construction Demonstration Project" in 2015.
