Summary of internship for students majoring in transportation engineering

Sample internship summary for students majoring in transportation engineering

A summary is a written material that analyzes and studies the experience or situation in a certain stage of work, study or thought. It can make the mind more focused. When you are awake, your goals are clearer, so prepare a summary. So what should the summary include? Below is a sample internship summary for transportation engineering students that I compiled for you. You are welcome to learn from it and refer to it. I hope it will be helpful to you.

Taijing Expressway (Taihe to Jinggangshan) is a component of National Highway 319 and is also the most convenient access to Jinggangshan Scenic Area. After completion, the project will shorten the driving mileage from Taihe to Ciping, Jinggangshan by about 14 kilometers.

The Taijing Expressway starts from Nanyuanlong Village, Nanxi Township, Taihe County, intersects with the Changfu-Taihe section of the Jiangxi-Guangdong Expressway, passes through 3 counties and cities, Taihe Airport, and ends at Xiaping Town, Jinggangshan City. The total investment is 2.291 billion yuan. After the project is completed, the original National Highway 319 will still be retained. The foundation stone of the Taihe to Jinggangshan Expressway will be laid on June 28, construction will start in mid-September this year, and it will be completed and open to traffic in the first half of 20xx. On June 26, 20xx, our class took a bus to Taihe for internship. We departed at 6:30 in the morning and arrived at 11:00 in the morning. After practicing in Taihe for 3 hours, I realized that the Taihe to Jinggangshan Expressway is part of the road network planning in Jiangxi Province. The tourist expressway is also a convenient access to Jinggangshan Scenic Area, with a total length of 62 kilometers. At the same time, a 22-kilometer connecting line from Xiaping to Jinggangshan Tourism City Ciping Town will be constructed. The Taijing Expressway project is constructed according to the standard of a full-line four-lane expressway, with a calculated driving speed of 80 km/h and a roadbed width of 24.5 meters; the connecting line has a calculated driving speed of 40 km/h and a roadbed width of 16 meters. There are 42 bridges on the entire line, including 1 main line extra-large bridge, 23 large and medium bridges, 218 culverts, and 3 tunnels, with a total length of 4,008 meters. Among them, the single tunnel on the left line of the Jindong Tunnel is 2,015 meters long, which is the longest in Jiangxi Province. The longest road tunnel in the province so far.

At present, tens of thousands of builders have overcome difficulties such as heavy rain, short construction period, high environmental protection requirements, complex terrain and geology, scientifically arranged construction, comprehensively accelerated the progress of the project, and strived to be completed and opened to traffic in May 20xx. During the internship, the chief engineer in charge of that road section gave us a detailed introduction to the compaction effect, methods, steps and road construction measures of the roadbed. Specifically, he said: climate factors affect the quality of roadbed construction, and different regions should conduct construction according to the local climate. Features: Choose a reasonable construction season. There is no obvious difference between the four seasons, but it is rainy in summer and the moisture content of the roadbed filling is difficult to control, so it is not an ideal construction season. At other times, there is less precipitation and moderate temperatures, which facilitates the control of the moisture content of the roadbed fill and the compaction of the roadbed. During roadbed construction, if the soil quality is poor, even if the loose paving thickness is moderate and the rolling compaction meets the specifications, it will still be difficult to achieve the compaction standard. Therefore, all roadbed fills must be tested. In the construction of highways, coarse-grained soil is generally used for roadbed filling. This kind of soil is well graded and has its own properties. Generally, as long as the mechanical rolling is reasonable and the thickness of the loose paving is moderate, it is relatively easy to meet the requirements of the specification. The asphalt surface layer consists of three layers. The lower layer and the middle surface layer are made of coarse-grained asphalt concrete, each with a thickness of 6cm. The coarse aggregates in the middle and lower layers are all made of limestone gravel. Although the material source is satisfactory, the grain shape is not good and the content of needle flakes is high.

Practice has proved that it is impossible to produce aggregates with a grain shape that fully meets the requirements using a crocodile stone rolling mill. In the oil surface construction of the Zhenjiang section of the Second Highway Bureau of the Ministry of Transport, the aggregates processed by hammer mills were used. Due to the good grain shape, the proportion design was smoother and the quality of the oil surface after paving was also higher. During this internship, we combined the things in the books with reality, and asked the experienced chief engineer for many questions that we did not understand at ordinary times, and we benefited a lot. I hope that we can often conduct internships like this in the future so that we can learn more. At the same time, I also experienced the hard work on the construction site and the scorching heat. Although our internship has ended, my heart is still beating. Friends, come on! Although the construction site is messy, it is these messes that form a powerful symphony that sings to the motherland. I believe that the construction industry of our motherland will be better tomorrow.
