Fortunately, there are still several sets of levels that are not being used for the time being lying quietly in Party A's warehouse.
Zeng Yiming asked Scar to borrow it. After all, as a craftsman, he was still a little reserved.
He was observing all the way. Scar was so familiar with this place, it was like going home.
Besides, if you have a tool like scar, you have to use it as hard as you can, because it won’t become scrapped after using it for a while.
After taking the measuring tool back to the construction site, he first needs to find the reference point, and then guide the point to the construction site step by step.
Fortunately, the reference point is only 500m away from the construction site, and the line of sight is relatively good. After the fat man held up the tower ruler and changed 3 points, we finally completed the first pass. This fourth-level reference point must be placed in a relatively fixed place. You can't measure today. , it will be gone tomorrow.
He used a cement telephone pole at the construction site and used red paint to clearly mark the measured elevation on the pole.
This is not over yet. We must use the data of this point as the reference point and go back and measure again. This task is called review of the allowable closure error. This is to review whether the previously cited points are within the allowable deviation of 1 mm. , if it exceeds this range, congratulations, the measurement is unqualified and can only be measured again.
After the introduction point is completed, then measure the original ground elevation. This only requires finding a place with a wide view to set up and adjust the level. An interesting thing about the level is that every time the instrument is set up, the U-shaped tube must be inserted. Adjust the bubble to the center point to make the center wire of the instrument's eyepiece perpendicular to the vertical axis of the instrument.
At this time, the bottom of the tower ruler is placed at that point on the telegraph pole. The data read on the tower ruler is called the rear view reading. By rotating the eyepiece 180 degrees, the reading read at any position where the tower ruler is placed is, They are all called forward looking readings.
Soon, he completed the measurement of these original ground data. Because the terrain was highly undulating, he had to complete it by turning points during the process. These subsequent turning points did not need to be reviewed, so it probably only took about 100 hours to measure the part above the ground. half an hour.
The difficulty was in measuring the underwater part. Fortunately, Dao Ba had built a steel pipe frame before. Zeng Yiming adopted a very simple and crude method. He found a worker and asked him to wear a safety rope and hold the tower ruler to complete the task with him. Work.
I saw that he only measured the data he needed on the steel pipe riser. The rest was for the worker to use a tape measure to measure the distance between these points and the fastener overlap (steel pipe connection position) one by one. Is the bottom steel pipe not What needs to be measured is that each steel pipe is 6m long. This is a fixed value.
He also roughly measured the length of the steel pipe exposed above the water, and finally he laughed. The water depth was about 1.5m. He returned to the office and asked Chengzi to check the weather data for him. If everything was normal, he would ask Scar to find an excavator and earth-loading truck tomorrow and spend two days building the cofferdam.
It happens that there is an abandoned construction road under the bridge left by the original bridge construction to intercept the water from upstream to downstream, which can save a lot of pumping station costs.
Zeng Yiming returned to the office, and Scar was sitting there happily drinking tea. When Scar saw him entering, he quickly stood up and took the initiative to give up his seat. He greeted warmly: "Brother, come here and have a sip of tea and blow on the electric fan. Look at how sweaty you are. Your clothes are soaked through."
Zeng Yiming was not polite and took the big teapot he handed over. He walked to the electric fan and turned it to the highest setting. He held up the teapot and blew it hard. When the tea in his hand was no longer so hot, he felt cool. Came down. Then he picked up the teapot and took a sip. He felt refreshed and breathed out comfortably.
Zeng Yiming got a thermos bottle and refilled the teapot, then sat down, found a comfortable position and asked: "When I measured it just now, the water flow was not so fast. We will build the cofferdam tomorrow. Do you know that in Where can I get soil around here?”
Scar thought hard for a moment, stroked his bald head, and said with a smile: "Our village can do it. Our village belongs to the urban-rural fringe area, less than five kilometers away from here. There is a special piece of land in the village where people build it. The spoil yard rented by the road team still has about 100,000 cubic meters of soil piled up."
Zeng Yiming took out a pen and paper and wrote calculations while saying, "Oh, well, you know our construction period. You go coordinate it in the evening, and tomorrow you go find an excavator to collect soil from the spoil site. Five double-bridge earth-moving trucks and an excavator are here on the sidewalk. The cofferdam requires about 3,000 cubic meters of soil, and 2 high-power water pumps are needed. They must be in place tomorrow night. If we are lucky, we will have it the day after tomorrow. We’re eating wild fish. When the time comes, we’ll call Party A’s congratulator and we’ll have a full fish feast.”
The fat man was so excited when he heard that there was something to eat, he hurriedly suggested: "What about a whole fish feast? Isn't it delicious if we eat spicy hot pot fish?"
Cheng Zi thought more about it. He patiently explained to the fat man: "Don't cause trouble. Xiao Ming is doing business. You are not allowed to ask for his opinion when treating guests to dinner? What if he can't eat spicy food?"
Scar chuckled: "Don't worry, even if there are no fish in the water, I will find a way to get the fish out, so it won't affect the fish treat."
Zeng Yiming didn't take this to heart. After he arranged things for Scar, he took his two friends back to school. He was sweating all over and now he was hungry and tired.
On the way, Chengzi said enviously: "Xiao Ming, I really have you, I don't have to go to the city, I can make a lot of money this time!"
The fat man echoed: "That's right. I already knew that following Xiao Ming would make me eat meat."
Xiao Ming glanced at the little fat man, and he suddenly thought of a problem. He didn't have an ID card and couldn't apply for a bank card.
Now that he was in this situation, he couldn't get away from it. It seemed that he had to ask the fat man to go back and go back to the old man to apply for a bank card and send it to him.
"Fat man, you go home tomorrow morning to help me do something. Ask my grandpa to apply for a bank card for me. After you get the card, come back tomorrow or the day after tomorrow." After Zeng Yiming finished speaking, he glanced at the fat man's aggrieved look and said, He smiled and said: "Don't worry, the whole fish feast will definitely be the night after tomorrow. Everyone will be busy at noon. If you drink at noon, you will not be able to continue working in the afternoon."
The fat man nodded happily.
"Don't worry, you two. I'm temporary now. I'll let you experience life by the way. If you feel it's not suitable, don't you still have more than two years? When it's time to fill in your application for the college entrance examination, fill in your favorite major, then Better than anything else.”
After Zeng Yiming returned to school, under the strange eyes of the dormitory master, he took the two of them to the bathroom to take a shower and change into clean clothes.
He still had dozens of dollars in his pocket, so he decided to be generous and treat them both to a small restaurant outside to celebrate his first step.
The fat man bought three popsicles from the canteen outside the dormitory for 1.5 yuan.
The three of them happily ate popsicles and walked outside the school gate.
The fat man smiled and said, "I want to eat vinegar-based tenderloin for five yuan a portion."
Chengzi continued: "Actually, the sweet and sour pork ribs are also good! The crucian carp with Huoxiang flavor is also delicious."
After hearing this, Zeng Yiming laughed and waved his hand: "Arrange!"
