Summary mode of highway engineering construction 1 article
The year 20xx is coming to an end, and a new year is coming. Unconsciously, the XX project has been started for half a year. In these six months, happiness is accompanied by sweat, and growth is accompanied by ups and downs. Under the care and guidance of the leaders, I grew up slowly, from a naive student who knew nothing about highway engineering to a technician who could manage the construction independently. Thank you for your careful guidance and care, and thank you for your active cooperation.
I. Project Quality Management
Technicians working in the construction front line should be responsible for the quality, safety and progress in the construction process, report the problems that need to be solved and improved in the construction in time, and propose solutions to the leaders. In the work, we should deal with the relationship with the construction personnel and the supervision owner, and everything is based on ensuring the progress, quality and safety. Engaged in technical work, but also have a good attitude of learning and studying. It is far from enough to rely on what you have learned from books. You must have rich field experience, which requires a detailed understanding of the construction drawings in advance and a targeted construction process in your mind.
As an engineer, his work is also very hard. It is necessary to make a good plan and prepare for the follow-up work in advance to ensure that the follow-up work is not in a hurry, and there is no shortage of east and west, which will not affect the construction period. It is also necessary to do a good job in supervision during the construction process, conduct a comprehensive inspection of the project quality, and pay attention to potential and emerging problems during the construction process.
When put forward and corrected, the construction process of special procedures shall be tracked and inspected in the whole process to ensure that each procedure is qualified, and the supervision and technical personnel shall be cooperated to patrol, solve various problems found, and make timely rectification to ensure that the construction quality of each link reaches the standard.
Within half a year's construction time, * * * plans to complete two slab culverts and six round pipe culverts, and the engineering quality reaches the qualified standard. No safety accidents occurred during the construction period, and the site construction was in good order.
Two. Experience and lessons
Construction not only needs the support of technical theory, but also needs rich field experience. As a non-engineering graduate, I need to know more about the key and difficult points of construction, the problems that easily appear and the solutions. If I don't understand them at the scene, it is necessary to communicate with the shift workers. Through communication, I not only improved their professional quality, but also increased my own experience, so that the construction force and technical force of our company can develop and grow together.
Third, deficiencies and improvements
Although I have made a big step towards my goal in the construction work in the past six months, I still see that I still have many shortcomings. Unstable development, lack of theoretical level, sloppy thinking and lack of experience are all directions that I need to correct. In the coming year, I believe I will find the direction, and I will definitely make a breakthrough and achieve success!
