Regarding the cable-stayed bridge, the technical difficulty is very great, and it is impossible for the Ministry of Engineering to complete it, so they can only assume and speculate according to the construction method and experience of the bridge in the past.

The same is true of this volume of design drawings, of course, this is much more professional than Zhao Ran's conception, and many of the details of the design are unknown to Zhao Ran. Zhao Ran can only draw the appearance of the cable-stayed bridge in his mind, which belongs to the concept map. In the drawings of the Ministry of Engineering, there are many decomposition structure diagrams, accompanied by a long list of data.

Zhao Ran is not a professional in construction, but it can be seen that the Ministry of Engineering has done its best, and Zhao Ran has always respected the construction method of this era, and always believes that these craftsmen have the wisdom and skill of ingenious workmanship, so he accepted this design.

Zheng Langzhong said: "According to the abbot's request, our camp division did a field survey in the early stage, and prepared to build the experimental bridge on the Jinchuan River to verify the cable-stayed construction method. ”

As he spoke, the deer master took out another scroll and spread it out on the stone table. The top is the map of Yingtianfu, which marks the trend and location of the Jinchuan River, and the bottom is the selection of the bridge site.

Lu Dajiang explained that the Jinchuan River originates from the northern foot of Qingliang Mountain, connects Xuanwu Lake and enters the Yangtze River, and the narrowest part of the whole river section is 12 zhang, generally up and down 18 zhang. This width is a bit too long for a stone arch bridge, and the construction of pier bridges will seriously affect the traffic of ships, so there has been no bridge on the Jinchuan River.

Zhao Ran suggested that the Ministry of Industry choose a place to build a bridge to verify the cable-stayed construction method, and the Department immediately selected this river, and after a recent month of investigation, the bridge site was set in Sajiawan.

The width of the river surface of 18 zhang is about seventy percent of the width between the two piers of the Yingtian Yangtze River Bridge, which is of great reference significance.

This is a new model of bridge building, and the Ministry of Engineering has no experience to follow, so it can only rely on the craftsmen to explore it on their own.

Master Lu took out another list and respectfully presented it to Zhao Ran: "Abbot Zhao, the lower officials will definitely do their best to build the Jinchuan River Bridge, but these materials are calculated by our craftsmen, and I ask the abbot to prepare them." ”

At the head is four fifteen zhang long stainless steel cables, so that every time the length of each zhang decreases downward, four are needed, and it is reduced to five zhang. According to the requirements of the Camp Division, these stainless steel cables must be able to carry a thousand stone pulling!

The value of 1,000 stones, Zhao Ran asked them how to get it, and the answer of Lu Dajiang and Zheng Langzhong was that they roughly calculated the number of green bricks and steel keels required for the Jinchuan River Bridge, and believed that the total weight of the bridge body was around 10,000 stones, so each stainless steel cable should be able to withstand at least 1,000 stones.

This is an empirical algorithm, which has no practical significance for Zhao Ranyan. When refining steel ropes, he did not have the means to measure whether the tensile force of the steel ropes reached 1,000 stones, and this value had to be converted in a practical way.

The deer master continues to introduce the list.

Below is the stainless steel keel used in the bridge body, as well as the steel plates laid on the keel, the amount used is very large, and the deer master designed to lay fifty thin steel plates of this kind of two zhang long, three feet wide, and half an inch thick on the five main keels - he didn't know how Zhao Ran refined the kind of steel plates he had described, but the immortal methods were not something he could understand, and whatever Abbot Zhao said, he would calculate.

The total weight of such a steel plate is about 80,000 catties, plus the steel cable and keel, and the amount of steel is more than 100,000 catties.

Looking at this list, Zhao Ran felt a headache again, but the headache was a headache, and he had to "take it all".

He had contacted the Artifact Pavilion before and asked about the steel used in refining the magic tools of the Artifact Pavilion, and the Artifact Pavilion replied that there was special effect steel, which could meet the needs of building the bridge. Therefore, he was ready to place an order to purchase now, so he said: "You guys start, according to the drawings on both sides of the Jinchuan River to build bridge piers and towers, how long will it take to complete?"

Master Deer said: "Three months." ”

After Wang Zongyi took Zheng Langzhong of the Ministry of Industry and the master deer away, Zhao Ran packed up and prepared to go to Lushan, and was about to fly to the Yuanfu Palace, so that Zhou Keli and Ling Congyun could ride the infinite lotus to pick him up, when he saw a white light coming from the sky and falling straight down to Jingyang Tower, which was the cloud haze lily that Rong Niang was riding.

Rong Niang smiled and groaned from the clouds and lilies, and the temperament of the whole person has changed, and the beautiful eyes are overflowing, and the more beautiful and moving.

Zhao Ran was stunned, turned his wheelchair and leaned up: "This beautiful fairy, I admire the trail at a glance, can you leave a flying talisman and talk about your life ideals when you have time?"

Rong Niang pursed her lips and said, "I'm an archmage now." ”

Zhao Ran hurriedly asked, "What kind of thing does the divine sense entrust you?"

Rong Niang said: "It's okay, I have an eighth-order talisman." ”

Zhao Ran applauded: "It won't be an upgraded version of Yujingtong Tianfu, right?" Anyway, the broken talisman you gave me has been used twice, and I haven't escaped each time, I really don't want to use it, but I have already placed my divine sense, and I really can't." How do you think I can make up for this loss?"

Rong Niang said: "It's simple, just marry you." ”

Zhao Ran nodded: "Reluctantly." By the way, you just came, and you always borrowed someone else's flying magic weapon, which is very shameless, and this time it can be regarded as catching the cloud haze lily. Accompany me to Lushan. ”

Rong Niang pushed Zhao Ran onto the cloud mist lily, and after the lily was closed, Zhao Ran spread his hands: "Help me get out of the car." ”

Unexpectedly, Rong Niang kicked the wheelchair over, and Zhao Ran suddenly fell over on the transparent crystal base, and said helplessly: "In terms of serving people, you have to learn more." ”

Rong Niang asked, "Learn from Xiao Su?"

Zhao Ran coughed dryly: "It's not early, let's take off quickly." ”

The cloud mist lily immediately rose into the air, and Zhao Ran looked at the bustling streets and alleys of Yingtianfu through the transparent base under him, and was stunned for a while.

Rong Niang asked, "Why are you going to Lushan all of a sudden?" I just came, and you didn't let me rest for a while. ”

Zhao Ran said: "You have been resting for several months, still resting? No way, the time is too rushed, I need to refine a large number of materials, I must go to the Instrument Fu Pavilion and ask them to refine a batch of steel plates." ”

"What steel plate?"

Zhao Ran briefly talked about the need to refine cables and steel keels.

Rong Niang said: "Don't go to Lushan for this matter, go for nothing, the refining workshop of the Instrument Fu Pavilion is very busy, and I don't have time to take your work." ”

Zhao Ran asked, "Where are you going?"

Rong Niang said: "I've broken through the border, and you haven't congratulated me yet." ”

"Come on. ”

"What? Hey...... Let go of ......"

"Give you a hug and congratulations on your exit...... Ouch, don't hit your stomach!"

After a while, the cloud mist lily came out of Yingtian and headed towards the direction of Gesoap Mountain. After bypassing Gesoap Mountain, they landed in a mountain range in Yuanzhou.

Rong Niang introduced: "This is the Taixuan Pavilion, instead of going to the Fu Pavilion, it is better to come to the Taixuan Pavilion." The materials refined by the Instrument Fu Pavilion are magic weapons, the materials refined by the Taixuan Pavilion are materials, and most of the materials refined by the Instrument Fu Pavilion come from the Taixuan Pavilion. ”

Zhao Ran's eyes suddenly lit up: "As soon as you say this, I remember, Yang Zhenren is the great elder of the Taixuan Pavilion, it's your fourth grandmother, right?"

"Fourth grandmother!"

"Almost. ”

"Okay, I'll call Xiao Cunxin out, what do you need, you talk to her. Let's talk about it first, you can't trick her!"
