Engaged in engineering construction for40yeats. today. I suddenly had this idea. sort out the past construction life experience. describing the principle of engineering structure with physical knowledge. and the relevant physical knowledge applied in the construction project.
译，从事工程建设40年，今天，突然有了这个想法，好好整理过往建设人生中经历，用物理知识述说工程结构原理，以及工程建设中应用到的相关物理知识。
I remember when I was in Wuxi municipal. during site survey and setting out. total station used. the backward looking orientation in the measurement step is the Application of physical knowledge. later. when the lime line was excavated. there are several cement poles blocking the line. in order to complete the setting out task. the three of us decided to pry it open with a roadside tree pole. it goes without saying that I thought of the lever principle. from then on. I realized the importance of using physical knowledge in my work.
译，曾记得在无锡市政时，工地测量放线中，运用全站仪，测量步骤中后视定向，就是物理知识的运用，后来在撒石灰线开挖时，又有几根电杆拦在线上，为完成放线任务，我们三个人决定用路边树杆撬开，不言而喻的想到了杠杆原理，从此，我意识到物理知识，在工作中运用的重要性。
Before going to singapore to help build. ask me whether I choose to be a carpenter plumber or bricklayer. I said. I'd better not have done it. well. you work as a reinforcement worker and write our expatriate agency in singapore. let you do the steel bar turning. I really accepted the three-month urgent training and practical challenge. when the cantilever beam and the main beam intersect. the cantilever beam reinforcement. they are respectively located above the upper and lower bars of the main beam reinforcement. position of pressing along the wall on the main beam. treatment of door frame beam and embedded parts. all need mechanical knowledge in physics to fully understand. a few years later. I joked with the boss of the alliance company. you xuweijun, I've heard your name. here. can you accept the dual challenges of technology and physical fitness. I said with a smile that I can cope with it just40this year. sure enough. work stars tomorrow. the next morning. I took the drawings. after a tour. it was a shaft at the intersection of two ditches. the shaft is2m wide.4m long and4m deep. after careful analysis. the technical difficulty mainly lies in the bending of reinforcement. one person'operation can pay more physical energy. the first thing I think of is that physical knowledge is labor-saving. Especially bind it and install lifting rings. the positions of the two lifting rings shall be balanced. and the lifting shall not damage the shape of the reinforcement. the reinforcement shall be fabricated from8a.m. to4p.m. Chinese guest workers Nijunxi and sun zhaolou praised me and won face for the Chinese people. I also want to take a group photo with them. Through this. I feel the importance of mechanical knowledge.
译，在去新加坡援建之前，征询我选择从事测量放线，还是木工管工或瓦工管工，我说，最好是我没干过的，那好，你就考钢筋工，到新加坡，我们外派机构去函，让你做钢筋翻样工作，我真的接受了为期3个月的急训实干挑战，动手一干，细细体悟，悬挑梁和主梁相交时，悬挑梁的钢筋，分别位于主梁钢筋的上下层筋上面，压沿墙在主梁的位置，门框梁及预埋件的处理，都需要物理中的力学知识，才能彻底理解，几年后，到联明公司，老板开玩笑说，你，徐卫军，我久闻大名，到这里，能接受技术和体能的双重挑战吗？我笑笑说，今年刚40，还能应付，果然爽快，明天上班开始，第二天早上，我拿了图纸，游阅了一下，是两条水沟相交处一口竖井，竖井宽2米，長4米，深4米，我认真分析一遍，技术难点在钢筋弯曲，一个人操作，体能付出较大，我首先想到的是物理知识省力，尤其在上面绑扎好后，装吊环，两个吊环位置要平衡，吊起又不损坏钢筋形体，从上午8时开始钢筋制作(下料)，到下午4时绑扎完成，中国客工倪俊喜，孙召楼表扬了我，(说)为中国人争了面子，还要我与他们一起在那(钢筋笼子前)合影留念，通过这事，我倍感力学知识的重要性。
it is a review of hydrodynamics to do hydraulic engineering and contact hydrodynsmic pressure. Hydrodynamic pressure is the comprehensive Application of resultant force. buoyancy. density and other knowledge. Application of foundation reinforcement method. compression and extrusion are actually applications of the basic principles of physics. Deep compaction method. its principle. compact the soil. drain and consolidate and improve the bearing capacity of the foundation. Here I will not give examples one by one. let me say a few more examples of physical knowledge required in addition to building structures. I saw a construction site under the high-voltage line. there is no insulating dry bamboo support fence under the line. a steel bar takes more than5meters of steel bar on the scaffold. as soon as it was lifted. the other end of the steel bar was absorbed by the magnetic field of the high-voltage line. the electricity suddenly stopped. soon, the electric power bureau's detection car detected it. A few people came down and took pictures. then they knocked down the steel worker with their own bamboo pole. tragedy is over. the reason for the discount accident is that the project leader does not pay attention to it. the steel worker himself lacks the basic knowledge of electricity. I also met an electric welder. when cutting the oil drum. I didn't understand the principle of thermal expension of the vapor in the oil drum. cause an explosion. Fortunately. the oil barrel was far away from him. and there were no casualties. later. master Huang fengmei from jiangdu taught me a lot about this. in fact. electrical products used in life. burning gas . oil ete. are inseparable from physical knowledge. Even our daily shoulders. hands and arms contain profound knowledge of physics. therefore learning physics well is important for work and life. at least. it can reduce blind collision and unnecessary injury. lnject harmonious notes into society.
译，今做水利工程，接触动水压力，更是对流体力学的回顾，动水压力，就是合力，浮力，密度等知识的综合运用，地基加固处理方法中，（运用）压和挤，其实都是物理学基本原理的应用，深层挤密法，其原理是，挤密土壤，排水固结，提高地基的承载力，这里我不一一举例了，我再说几个建筑结构外，需要的物理知识例子，我看到过一个工地，在高压线下，由于线下没用绝缘干毛竹支护防拦，一个钢筋工在脚手架上拿5米多的钢筋，刚扛起，钢筋另一端就被高压线磁场吸去，电一下子停了，很快，电力局的检测车到了，下来几个人，拍照后，用自带的竹杆敲下那钢筋工，一场悲剧就此结束，分析事故原因，无非就是项目负责人不重视，那个钢筋工本身缺少电的基本知识，我还见过一个电焊工，在切割空油桶时，因不懂油桶内（废）汽体受热膨胀的原理，造成爆炸，幸好油桶离他远去，无人伤亡，后来，江都的黄凤美师傅，教了我很多关于这方面知识，其实，生活中用的电器产品，烧的气，燃的油等，都离不开物理常识，就连我们日常的肩扛，手拎，怀抱，都含有深奥的物理学知识，所以，学好物理，对于工作，生活都是重要的，至少说，可以减少盲目的碰撞和不必要的伤害，给社会注入和谐的音符。
