——    "This land is good. A large area is a natural foundation." Ye Qidong looked around and nodded repeatedly.  The foundation refers to the stratum that bears the weight of the building. It is called "foot" in some places. In addition to artificial foundations, there are also a small amount of natural foundations in nature. The natural soil layer can carry the building without processing or filling. It is a good choice for developers.  favorite.  With only a flashlight guiding the way, the four of them began to sneak along the "excellent arc" speculated by Ye Qidong.  As for why Ye Qidong speculated that the next section of the road would be an extremely long arc, Lin Siyu asked again afterwards.  The answer given by Ye Qidong was also very clear: "I like to think about the worst aspects of things. I have conspiracy theories. I hope you can understand. If you can't, forget it." Lin Siyu said that of course he can  Be considerate, who would allow a conspiracy theory patient in his Zhongzhou team?  She was already used to this kind of "patient".  As they walked, the four of them realized that this circular passage was much longer than expected. It hadn't been decorated yet. Fortunately, from time to time, lights installed by workers could be found on the roadside. Many of the lights had run out of power.  A few are still surviving, and turning on the switch can provide weak lighting.  This is the first time the Lord God has given a slightly humanistic mission plot today.  Suddenly, Ye Qidong and Li Tui, who were walking at the front, stopped, and both of them looked towards the gap in the wall on the right.  The right side was originally a rough closed wall, but a gap suddenly opened in a certain section of the road, which is really suspicious.  Seeing this, Li Tui couldn't help but feel excited.  Before continuing to walk this circular passage to the end, you will be the first to hit a clue that looks valuable.     【coming!  Finally here it is, the cause of death!  As for the cause of death of this lonely ghost in the Xinantai construction area, the Lord God should give a clue.  Once the clues are revealed, the rest is up to us to reason on our own. Once our reasoning is wrong and we go astray and wonder what we have missed, it will lead to loss of life, right?  The final analysis of Barton's death was that their team did not expect that Ghost No. 1 would visit his girlfriend at that time.  In fact, the Lord God has already given clues and the daily activity time of Ghost No. 1. If Sima or I were present at that time, they would have predicted that in time, and Barton would not have died So, now this  How does Ghost No. 2 want to take away our lives?  Oh, Lord God, I won't let you succeed easily!  I won't let go of any clues, any!  ] Walking into the half-human-high gap in the wall, what you see is an unfilled cylindrical landform with many broken gaps.  "Is this? Made by a pile driver?" Although he is not a civil engineering major, Tsutomu can still recognize the scene in front of him at first sight.  It is the pile left behind when the pile driver drives the foundation, but this pile is a little special.  Because if a ground building is to be built on the ground, the ground will bear a lot of pressure. It is necessary to ensure that the ground has sufficient strength to resist the pressure. This is often difficult to achieve, so the ground that bears the building must be reinforced or  To improve the bearing capacity of the ground, we came up with the idea of ??driving piles on the foundation so that most of the weight of the building can be transferred deep below the ground through the piles, because the foundation at this location has much greater bearing capacity than the ground.  Regarding how deep the pile should be driven, it depends on the distribution of the strata underground (technically called the geological structural layer). If it can withstand the pressure of the building enough, the pile will be driven to this point. If not, it will have to be deepened.  "There is no filling. Are you not going to deal with this pile? In theory, it should be a wooden pile or a steel pile." "Wood piles are rare now, and there are not many steel piles. They are generally reinforced concrete piles. It can be  Preset, it can also be poured in place! ""Poured in place?" I don't understand at all." Ye Qidong was about to explain, but was interrupted by Lin Siyu's doubts: "Looking from above, this cylindrical pile is at least thirty meters upward.  "Is this a trace left by a pile driver?" "Yes." "It's hard to say how deep the foundation should be. It depends on the height, structural form, and use of the building, combined with the engineering geology and hydrological conditions.  , calculated data, but looking at the situation here, it shouldn't be a problem to build a foundation of forty or fifty meters. The underground club has also been built with a new layered foundation, which is estimated to be more than twenty meters." Ye Qidong said roughly.  After the ground estimation, a fuzzy data is given.  "Wood piles are rare now, and there are not too many steel piles. They are usually reinforced concrete piles, which can be preset or cast on site! You guys really don't seem to know anything about the equipment on the construction site.  After placing the steel cage, you can put the slide?Pouring concrete.  When pouring concrete, it is carried out continuously, and the layers are vibrated and compacted. The height of the layers is determined by the tamping tool.  Generally it should not be larger than 1.5m.  When concrete is poured to the top of the pile, it should appropriately exceed the design elevation of the pile top to ensure that the elevation of the pile top meets the design requirements after the laitance is removed.  "Ye Qidong explained a bunch of things to himself, and it was exactly what he said. He is a person who has a photographic memory. He made sufficient preparations before coming here. He remembered the information he read clearly and came to it as soon as he opened his mouth.  “I don’t understand at all.  " Now he almost worshiped Ye Qidong completely. He found that the main god had arranged a knowledgeable and knowledgeable god for our Zhongzhou team. It was definitely a wise choice for Li Tui to save Ye Qidong at all costs. " But this time  It was not Ye Qidong who explained this time. Li Tui said that he also had some knowledge in this field: "There are two major processes in piling, the drilling process and the pouring process.  You can't drive a deep pile and then leave it hollow, right?  This will only weaken the bearing capacity of the original foundation, rather than strengthen it.  Driving piles deep into the ground below the foundation and then pouring them is a very good method of reinforcement.  Cast-in-situ is a form of reinforced concrete piles that are more maneuverable than preset ones.  By the way, Mr. Ye, lend me your mobile phone.  " At the end of Li Tui's speech, he suddenly changed the topic to Ye Qidong's mobile phone. Ye Qidong curled his lips and took out his mobile phone from his arms. In this era, large-screen mobile phones have not yet emerged. Nokia and Motorola are quite popular. Ye Qidong's mobile phone is  Motorola. The brand of the mobile phone is not important, as long as the Internet is available. Li Tui opened the browser, entered the search engine and typed a line on the nine-key keyboard without thinking. Lin Siyu and Ci both came over to share, and found that Li Tui was searching for pile drivers and drills.  Expert knowledge on holes “Why are you searching for this?  " He couldn't help but ask every time. Li Tui winked at the two of them: "This time it's very difficult. We have to make good use of all available resources around us. Since he has a mobile phone, if we don't use it, we will be guilty of ourselves.  .  Haven't you ever wondered why there are mobile phones?  And there is still a signal!  " When Li Tui said this, Ye Qidong was confused. Lin Siyu and Ci both understood instantly. "Difficulty is not a problem. The more difficult it is, the more we must seize all available resources around us.  I feel like we are one step closer to the truth.  Come, take a look at this it should come in handy.  ” I came back to read it every time, but Lin Siyu has a strong reading ability and has read it all. The content searched on the screen is the content in Baidu Encyclopedia, which roughly refers to the two major processes in the working process of the pile driver: drilling process and  The pouring process is roughly divided into: drilling machine in place → drilling → quality inspection → hole bottom cleaning → hole cover → moving the drilling machine. The process of pouring concrete is roughly divided into: moving the cover plate to measure the hole depth.  , place the steel cage vertically → place the concrete slide → pour the concrete → insert the steel bars on top of the pile. After the drilling machine is in place, start drilling. After drilling, check the quality, then strictly clean the soil at the bottom of the hole, and then come to the final step.  An important step is to move the drilling rig to the next pile position! Remove the drilling cover and recheck the hole depth, hole diameter, hole wall, verticality and soil thickness at the bottom of the hole. If there is any failure to meet the quality standards, it should be dealt with.  After passing the inspection, proceed to the next process. After the hole inspection, the pile hole construction record should be filled in. Then the hole cover should be covered, and the drilling rig should be prevented from driving or walking on the cover before moving to the next step.  The information is very long. The screen of the Motorola mobile phone is not big. It took Li Tui flipping through four screens to finish it. He didn’t care whether Cidu’s reading speed could keep up. He only read it twice.  He returned the phone to Ye Qidong. After reading this, he suddenly realized, "Ci'ao, why is it so scary? I rarely watch the news, but I accidentally watched it last time.  The news I received actually had some connection with this accident!  Damn it, I don’t believe this is a coincidence. No wonder I was chosen. Some things were really planned long ago.  " "What news?  When did this happen?  "Ye Qidong asked. Of course he would not tell him that he saw the news in 2013. He skipped the question of time and said quickly: "I remember seeing a piece of news last time, about a construction site in Nanjing.  After the pile driver transferred the pile position, the pedestrian fell in because the cover plate of the hole was not completed!  It was a full month after the man fell that he was discovered!  " "Oh, is it really that you can't die anymore?  ". "What do you think?  "Cidu sighed. "Fortunately, we didn't fall into the hollow pile driven by the pile driver.  "Lin Siyu touched her chest and said. [Huh?]  As soon as she said these words, Cito's heart jumped into his throat.  Both he and Li Tui reflexively looked upward.  When I was sure that there was no danger, I breathed a sigh of relief.  【Haha, I'm overthinking it. If such a big pile driver were to drive piles directly towards our area, there would really be no way to hide.  ] However, Li Tui miscalculated, whatever he was afraid of would come to him!  Jump!  There was a muffled sound, and a gray-white Optimus Prime fell from the sky.
