Wu Yanyi turned around and saw that it was Zhang Shancai, who was naked, wiping the sweat on his face with a sweat towel.

He walked over and nodded: "Brother Zhang! How is this tile kiln business? ”

"Is it really Takero? See Takerou for the villain! He couldn't believe it, but suddenly found that he hadn't saluted yet, so he saluted Wu Yanzhi.

After saluting, he continued: "This business is not good now! Last year's harvest was not good, and few new houses were built in a few years. The villain heard that this government is going to burn what kind of cement? Will Wu Lang find a way for the villain to live? ”

At that time, people called finding a job "living on the road".

"Of course it's no problem, there will be an additional vertical kiln for burning cement, I'll tell them, you have to learn this cement-burning technology, and you won't be afraid of running out of food in the future!" The Way of Martial Arts.

"Then thank you Takerou!" When Zhang Shancai heard this, he was extremely happy.

Wu Yanzhi then turned around and introduced Zhang Shancai to Li Shaojiang.

Li Shaojiang said with a smile: "There is no problem with such a trivial matter, we also need locals like him!"

There are locals, things are much easier to do, didn't Wu Lang say how good this cement is? In the future, I am afraid that the whole country will be popularized one after another, and those who learn this craft first will not worry about food and clothing! ”

According to Wu Yanzhi's thoughts, this technology of firing cement, of course, is promoted throughout the country as soon as possible, which can be regarded as a great credit to himself!

"Gong Li! When are you going to start ignition? Wu Yanzhi asked.

"According to the current progress of the project, the fire can be ignited in 15 days, and the limestone and iron ore will arrive in a few days. Soon the crushing process will begin, and then the grinding process will begin.

In this matter, the contemptible people have arranged for a signing order and four prison officials to be in charge of this matter, please rest assured.

As long as we can do something, we will definitely not bother Lao Wulang! After all, Takero is also busy! "Young Master Li is very confident.

……

In a few days, in the afternoon, he will be supervised.

Today, the design of the bridge is still being discussed.

Zhang Dajiang and you, Li Shaojiang and others, still invited Wu Yanzhi as a technical advisor. In addition, Wu Yanzhi himself is also the person in charge of the winter lawsuit, so it is also appropriate to listen to his opinion.

There are still dozens of people in the conference room.

This time, Wang Zhiguan brought a total of five pictures! He revised the design plan according to Wu Yanzhi's suggestion, basically according to the plan of Zhaozhou Bridge.

After Wu Yanyi saw it, he began to listen to Wang Zhiguan introduce the revised plan: "According to Wu Langzhong's opinion, we have made great revisions to the plan of Fengchi Bridge. Like the Zhaozhou Bridge, it was changed to a large arch, and two small arches were designed on each shoulder to facilitate flood discharge......"

He explained it in detail this time! It is the same as the Zhaozhou Bridge, which is made up of 42 independent small arches.

In this way, each arch is relatively independent, easy to maintain, and between each small arch and the adjacent arch, it is connected with large iron nails to enhance stability.

In the width of the bridge, six iron tie rods were used to tie up the 42 small stone arches to enhance stability.

The depth of the foundation is three meters, and the average width is three feet wider than the arch stones.

After listening to his introduction, Wu Yanzhi felt not very satisfied, mainly because of the foundation, and secondly, when he was young, although he had inspected Zhaozhou Bridge, he was definitely not detailed.

I have traveled to Zhaozhou Bridge and remember some key points, such as the top of the bridge is "closed", the width of the lower end of the arch is 9.6 meters, and when it comes to the bridge deck, it is only 9 meters.

This is to increase the stability of the arch bridge, which is much better when resisting earthquakes.

As for the foundation, it's better to be cautious about this thing, and the geological conditions vary greatly from place to place.

The foundation of the Zhaozhou Bridge is very shallow, and it will not collapse if it stands for thousands of years, which does not mean that the foundation of the Fengchi Bridge will not collapse with such a shallow bridge.

So Wu Yan said: "This bridge can be considered from the bottom to the top, gradually reducing the width, a total of two to three feet." It's more stable that way! It is easier to withstand earthquakes and floods.

As for the foundation of the bridge, I will go to the site on another day to see how the foundation is underneath and then decide on the width and depth.

If the foundation is not strong, the bridge will sink quickly, and once it sinks, the deformation will be accelerated, and the bridge will collapse quickly! ”

"Now that the water level of the river is deep, the foundation is not easy to dig, and it is time-consuming and laborious to dig wells, how to detect the foundation?" Li Shaojiang reminded.

"It doesn't matter! I've seen someone use a very practical shovel that can be used to preliminarily probe the foundation, which is very convenient.

In the future, when the construction is carried out, further fine exploration can also be carried out, I will immediately let Shang Fang supervise the processing of a few, and go to the site in the afternoon of the next day! "The Way of Martial Arts.

Of course, he knew that the Luoyang shovel was not only convenient for tomb robbers, but also for ordinary archaeological and exploration foundations, especially in terrain like Luoyang.

……

On the third day, in the afternoon, outside Shangyang Palace, on the bank of the Gushui River.

Wu Yanzhi, Li Shaojiang, Wang Zhiguan and others came to the Gushui River. It's a cloudy day, and the breeze is blowing, but it's very cool.

The pale yellow river flows slowly southward, and the river is more than 20 meters wide at this time, and a small fishing boat of six or seven meters is heading downstream to the Luo River, the man on the boat is holding a penny, and the woman is washing clothes in a wooden basin.

The two of them looked over to Wu Yanzhi's side from time to time, and were very surprised to see so many officials and officials here.

Wu Yanzhi ordered people to take out four Luoyang shovels, as well as a few 3-meter-long poles.

The Luoyang shovel he made is two inches in diameter, in a "U" shape, and six inches in length! Don't look at this thing, it's a must-have tool for future generations of tomb robbers.

Of course, after I leaked the production technology of this thing today, within a few years, I will definitely become the favorite of the tomb robbers of the Great Zhou.

"Wu Langzhong, how to use this thing?" Li Shaojiang looked at these four very small iron tools and was confused! The rest of the people are about the same.

Wu Yanzhi smiled slightly: "Come!" I'll show you how! Don't look at him small, this thing can hit eight zhang or ten zhang without a problem. ”

The people did not believe it, and they were full of doubts! However, he did not dare to oppose it explicitly.

After installing the 3-meter-long wooden pole, he looked up at the terrain carefully, selected a place, and began to raise the Luoyang shovel with both hands and thrust it into the ground!

When you shovel down, you don't have the handle of the shovel, and then you pull it up with force, and it is a full shovel of dirt.

Everyone was stunned!

Wu Yanzhi shoveled another shovel, and then handed it to Wang Zhiguan, the person in charge of the scene, and said, "Prince, you just do what I do......

"Wu Langzhong, this thing is also amazing! Contemptible admiration! Wang Zhiguan was amazed!

He took the Luoyang shovel and looked at it carefully, and then asked those officials and craftsmen to start following Wu Yanzhi's practice, loading the Luoyang shovel and starting to explore the riverbed.

It took more than an hour to drill four 8~10 meter exploration holes by the river on the east side of Gushui! From the analysis of the soil brought out, there is a pile of sand underneath, which becomes denser and denser the further you go to the bottom.

From Wu Yan's point of view, there is an obvious layering between these five meters and six meters, and the accumulated soil below six meters is already very dense and can be used as a bridge foundation. Of course, the west bank of the valley will have to be explored.

Everyone came to the west side again, probing the riverbed, to the end of the Shen time, only to complete the exploration, in the middle of the punching, everyone has been for Wu Yanzhi's invention of the Luoyang shovel, praise endlessly!

Judging from the several detection holes north of Gushui, it is basically the same.

So Wu Yanzhi gathered everyone around him and briefly introduced his thoughts on the bridge base:

"Judging from the situation of this punch, there is no problem that about five to six meters can be used as a foundation. However, the abutment of the bridge was also enlarged, which was poured with concrete and steel bars added.

It doesn't matter if you spend a little more, you have to make sure that the bridge will last for decades. In addition, it is still necessary to drive piles, strengthen the foundation, and try to control the balance of the weight at both ends of the bridge to ensure that it can settle evenly in the future! ”

Uniform settlement is actually very important, even ordinary soft foundation houses, may also settle, after all, it is a large load added to the original foundation.

However, as long as it is evenly settled, the problem is not too big. If there is a small problem, it can be fixed, but I am afraid that there will be a big problem.

When everyone heard it, Wu Yanzhi's words were also very reasonable. This winter lawsuit is a project planning unit, as long as they are willing to spend money, they will be the supervisor has no opinion.
