Seeing Jiang Chen's expression, Lu Lao, who had not spoken, said to Jiang Chen: "Don't worry, we will measure the data and send a copy back to Nanshan." Pen ~ fun ~ pavilion www.biquge.info let our people in Nanshan use the computer to help us calculate, and we will know the result as soon as tomorrow morning. Many airports around the world will produce crosswinds both during construction and in use. So in this regard, we have a lot of lessons to learn from, and it's not a big deal. ”

Jiang Chen nodded after listening, but Guo Chengye was a little uncertain and said, "Old Lu, can this also be solved?"

"Why can't it?" Lu Lao said a little unhappily: "Let me tell you, there are many ways to solve it. I'll give you a few examples, for example, we can make certain changes to the Longshou Mountain, so that the wind affected by it changes direction or weakens, and it doesn't affect here. The most common method like this is directional blasting, which saves time and effort. In the past, there was an airport abroad, that is, during the construction, in order to reduce the impact of crosswinds on the aircraft taking off from the airport, the local area blew out a gap in the nearby mountain beam, thus successfully changing the wind direction and solving this problem. ”

"Is this okay?" Guo Chengye said in surprise.

"What's not to do, as long as there is no one living there, or if the people who live there are relocated, this measure can be taken completely. "Lu Lao didn't have a good airway.

"Bombing the mountain, is this movement too big?Lu Lao, do you have any other way?" Jiang Chen said. What he wants now is to be as low-key as possible, if such a thing happens again, then it is estimated that some people should make a fuss about this.

Seeing Jiang Chen's expression, Lu Lao nodded and said to Jiang Chen: "Yes, for example, let's build a windproof wall on the windy side of this runway, which can also work." However, this method is a last resort and is not commonly used at present, because there is an airport abroad because the windshield wall was blown by the wind, which caused an accident, so I do not recommend using this method in this desert. I'm actually more inclined to the third method, which is to change the direction and angle of the runway to eliminate the effect of crosswinds on aircraft take-off and landing. ”

"Change the direction and angle of the runway?" Jiang Chen wondered.

"Yes, when we design each runway, in addition to considering the terrain factors and the airspace accident of the take-off route, in fact, the most important thing is the direction of the runway. Each runway is determined by a combination of local wind direction throughout the year. In this regard, we did not think carefully, thinking that it would be enough to have the information provided by the local meteorological department, but we did not expect that there would be deviations. Therefore, in terms of wind direction, when we design and construct the runway, the orientation angle of the runway and the pavement (surface) angle of the whole runway need to be adjusted according to this wind direction and wind parameters. This kind of thing is commonplace abroad, so it's not a big deal. Lu Lao said to Jiang Chen.

"I'm fine, you're blamed too. In such a short period of time, it's pretty good that we've been able to get to this point. It's okay to make a little mistake, aren't we studying?" Jiang Chen said now as he looked at several old men.

"Okay, that's what I want is your spirit. Lu Lao looked at Jiang Chen and smiled. As he spoke, he took the lead and walked out: "Let's go, let's go around again, and leave the matter here to a few of their young people." ”

"Good work. Jiang Chen looked at Chang Qing standing behind him, that is, Lu Lao's student, and said. And Chang Qing shook his head and motioned for Jiang Chen to hurry up, Jiang Chen smiled slightly, then nodded at him, and then hurriedly followed.

The group took the hard hats issued to them by the construction cadres, and then walked into the comprehensive assembly workshop where the main body had risen. Yang Gong of the Second Bureau saw Jiang Chen and them coming, so he hurriedly greeted them and accompanied them personally. I saw him pointing to the normal construction site and introducing them to Jiang Chen: "Mr. Jiang, Mr. Lu, this is the No. 1 assembly workshop we are building." The entire assembly workshop is one kilometer long, 75 meters wide and 23.5 meters high. For the walls of the whole building, we first used reinforced concrete as the frame, and then we used local materials, using the sand here as the main raw material, and the hollow bricks were pressed under high pressure, and we used this brick to fill the walls. This kind of red brick has higher strength than the yellow mud and black-hearted bricks we usually use, and has good oxidation resistance. Our traditional red bricks may have gradually weathered and eroded in the next two decades of this wind and sand. But our hollow bricks can be placed in this wind-blown sand environment for a hundred years without any problems. What's more, this kind of brick is made of local materials and is easy to mold, so its price is only one-third of the traditional red brick, which can be said to be inexpensive. Just one saved a lot of money for Mr. Jiang and them. ”

"Hahahaha, thrift and thrift are our traditional virtues. You have done a good job in this regard, and I think I will let Xiao Jiang thank you well. I think it's just last night's roast whole sheep, many workers didn't eat it, when the time comes, let Xiao Jiang treat you to a good meal. Lu Lao laughed heartily.

And Jiang Chen also said with a smile: "No problem, on the day when this place is completed, I will invite everyone to eat roast whole sheep until everyone supports it." ”

"Oh、、、" The crowd around them cheered. In this era when living materials are not very abundant, if you want to eat meat, you are really eating meat, not commonplace, let alone the more precious mutton. So when they heard that there was mutton to eat, they were still full, how could this not make them excited.

"Then let's talk about it. Yang Gong felt the excitement of everyone, and then smiled at Jiang Chen: "To be honest, you will definitely not lose if we eat your meal." As far as the structure I mentioned before, the workshop building with a length of 1,000 meters and a width of 75 meters has basically no precedent in China. And you also require that there can be no column support in the whole workshop, and the construction is so difficult that we have encountered it for the first time. To this end, we also consulted with experts in building mechanics from a number of universities and research institutes to overcome this problem. In order to meet your requirements, we have repeatedly researched the traditional concrete slab roof or steel structure roof with a new roofing material that mixes steel and light alloy materials. The resulting roof is nearly half as light as the original bulky roof. The strength is nearly twice as high as that of a traditional steel roof. To be honest, I think this technology alone can apply for this year's Technology Innovation Gold Award. ”

"Hahahaha. Hearing Yang Gongda vomit bitterness, everyone laughed.

And Jiang Chenke smiled at Yang Gong: "So I said that I will only hand over a project like this to your second bureau to do, can I rest assured that others will do it? Besides, we are all old acquaintances who have worked together many times, will we still treat you badly?"

"Hehe, that is, you, if it were someone else, we would definitely not take this kind of project. Yang Gong also laughed.
