First of all, according to the requirements of the drawing teacher, that is, in the known environment, design the direction of a railway, and explain the problems needing attention in construction and the choice of construction scheme.
In fact, this is a good pit!
Because no matter which route you choose to take, you will design the construction of bridges, tunnels and culverts, which is only a matter of quantity. Then you have to consider whether the geographical environment of the construction will interfere with the transportation of materials. To put it bluntly, how to construct is the most economical and efficient. My classmate is said to have been doing this graduation project for two months, without looking up or blinking! Because if you can't do it within the time limit, you can't graduate smoothly!
However, I didn't do it. =
I managed to escape this reality because I went to the internship.
The school has rules. Students who go out for internship in advance will be treated as qualified in class performance, and the graduation involved in graduation can be handled according to the post of internship company.
I was lucky to escape.
But that doesn't mean I don't have to hand in my graduation project. When I was at the construction site, I was engaged in the position of tester.
The job of this position is to record the number of cement cubes and the relevant data of water-cement ratio in each construction. It can be said that every pier, abutment and tray of every railway bridge should be recorded. It is also necessary to make concrete for construction into test blocks and press them with a press after 28 days to see if this stress level can meet the requirements of the test. Or pull the steel bar with a tension machine every day to see how strong the steel bar is.
After returning to school, I threw the printed copies of these things made on the construction site to the teacher, and the graduation project was properly completed.
