The old things I repaired have become fine

Chapter 62: Terrible mentor, we are not even as good as a -year-old man!

Go up the mountain, go down the mountain, and climb to the top of the mountain. After turning a few corners, a village appeared in front of Shen Le:
The winding stone road extends between the green tiles and white walls, and the sound of gurgling water can be heard at the edge of the road.

On both sides of the road, low houses are closely connected. When you walk by, you can touch the green grass growing wildly on the roofs with just your hand.

The white walls were already mottled, and the steps in front of the door were covered with moss and sparse footprints.

...The atmosphere is quite good. If such a village is developed as a tourist homestay, many people will be willing to come and play, right?
Of course, he could tell at a glance that although the atmosphere of these houses was good, they were far from qualified in terms of protection value. Shen Le continued forward, and opposite the semicircular pool, a large house stood quietly:

This mansion was obviously the center of the village. The house was tall and the walls were thick. Even if you stood on tiptoe, you couldn't touch the tiles on the top of the wall. The paint on the two doors had peeled off, but you could still vaguely see the vermilion.

Zhuqi, the owner of this house was once an official, right? And his rank was not low, otherwise he would never dare to use Zhumen...

Shen Le was still observing the structure of the door, but the instructor had already taken the lead and crossed the threshold. Shen Le reached out to support the instructor and hurriedly followed, then heard the instructor say with a smile:
"Xiao Shen, let me ask you, what is the biggest architectural feature of this main hall?"

Pop test?

Shen Le quickly perked up. He observed carefully and answered confidently:
"The front groove of this main hall adopts the method of reducing columns, that is, a thick lintel is used to span the main room, the secondary room, and the side room, making the interior space appear quite open.

This kind of architectural technique is a typical feature of the architecture in southwestern Zhejiang during the Ming Dynasty.”

The instructor nodded slightly with a smile on his face, but said nothing, as if testing him to see what else he could figure out.

Shen Le calmed down, recalled the fragmentary hints from his senior brother, compared them with the building in front of him, and continued:

"Also, the semicircular arched petals and rolled edges of the main hall, as well as the bottom plate style, have very obvious Fujian characteristics. Teacher, you really found a good place!"

This ancient building and its restoration can be used to write a long article!

If you expand on this, you can even send a graduation thesis to a junior fellow student!

"Not bad!"

The instructor was finally satisfied and patted Shen Le's arm gently:

"I haven't lost my skills even after graduation. Come on, get to work!"

The surveying work had been completed a few days ago. Now, Shen Le and his fellow students were assigned a piece of land, each holding a small notebook, taking photos, observing, and recording:
"The east side of the main hall of the main house... the floor is rotten... Photo 1"

"The pillars on the east side of the main hall of the main house...are slightly decayed, the length of the decayed part is 10*5 cm, and it does not affect the building structure visually...Photo 2, Photo 3"

"The east side room of the main house... the window panes in the main room are loose, and some of them are rotten... Photo 4, Photo 5"

"The east side room of the main house... the dark room..."

Ah, the work of protecting ancient buildings is so boring. First of all, we need to survey and map, record its size, style and material.

Then, follow the order of roof, structure, extension, wall, floor, doors and windows, decorative components, etc., one by one, and record them all:

Where is intact?

What's broken? What's damaged?

Where is the fade?

Where are the inappropriate additions that conflict with the original buildings?
After visual inspection and recording, we will conduct a careful study to determine where the building structure is in danger, where it is too decayed, where it can be repaired, where it must be replaced, and where it is impossible to preserve it.

Make an overall report, list the evaluation and protection opinions. Once the budget is approved and the money is received, construction can start!

Shen Le and his two fellow apprentices were busy taking pictures, recording and filling out forms, while senior brother Zhuang carried a tripod and ran from east to west and from west to east.

After running a few meters, I put down the tripod, adjusted the direction, lifted up the surveying device, and poked the screen. After two minutes, I picked it up, changed the point, and continued scanning...

Shen Le was drooling and full of envy:
"Leica 360D laser scanner! RTC! I didn't even use it at that time!"

Scanning 200 million points per second!
Scanning range 0.5 to 150 meters!
Point cloud stitching, automatic imaging, automatic calculation, and automatic completion of real scene reproduction!
This is the only one I bought for 80 yuan… The boss only has this one, and he treasures it like a treasure. He has been a graduate student for three years and has not been able to touch it. If my senior brother had not applied for a research project in this area, he probably would not have been able to touch it either…

To survey an ancient house like this, they used to use a theodolite, a level, and a distance meter. It would take several people to work under the scorching sun for three to five days, and then they would have to jump into the hell of mapping.
The thing in my senior brother's hand is easily carried by him alone, and it is enough for a day.

He'll buy one someday!
Then, scan his old house from top to bottom, inside and out!
Uh, never mind, let's see if I can borrow it...

"Are you jealous?" The instructor came over and patted him on the shoulder:

"When we were doing this business, we climbed up the beams and used lead weights to pull the ink line and measure it bit by bit. You guys are really lucky!

——However, even if you have the tools, you can’t give up the basic skills! Any tool is for people to use, and people have to know how to use it! "

Shen Le nodded repeatedly. At a quick glance, the tutor was holding a wooden writing board with a stack of A4 paper on it, writing and drawing.

With just a few strokes, the structure of the beams, columns, and rafters in the main hall came to life on paper. Even the angle of the crookedness was exactly the same as what Shen Le had observed.

This is the real skill passed down by the senior master...

Shen Le had seen the hand-drawn drawings of ancient buildings by Liang Sicheng, and they were just like this, detailed, exquisite and meticulous.

The exterior drawings are comparable to the photos; the interior section drawings show every structure clearly and highlight the key points. Unlike computer drawings, which can make you dizzy if you look at them too much.

The instructor had always looked down on them, and for good reason. These students were used to surveying instruments and CAD, and had basically given up their hand-drawing skills...

What was even more frightening was that there were long sections of calculation formulas underneath the instructor's sketch. Shen Le looked at it for a few seconds and felt dizzy, so he quickly looked away:

The instructor is calculating the force structure of this house!
Not only does it take into account the load-bearing structure under current conditions, but it also takes into account the movement of components and changes in the load-bearing structure during the repair, straightening and reinforcement process.

Where should iron hoops be added, where should cracks be repaired, where should they be lifted, where should they be corrected?
During the component movement process, all these tasks must be calculated in advance so that they can be carried out step by step in an orderly manner... However, that is not a reason for you to calculate by hand!
