Water supply and drainage project plays an important role in the production and life of urban residents and is one of the important facilities to ensure the normal operation of the city. The quality of construction is closely related to urban life. With the continuous advancement of urbanization, China’s water resources are becoming increasingly scarce. Therefore, the construction quality of the water supply and drainage project must be guaranteed to achieve the maximum water-saving effect. The quality of the construction of the water supply and drainage project not only affects the normal use, but also has serious water waste. So, it is necessary to do a good job in all aspects of project management. The main function of the water supply and drainage pipeline is not only to collect and transport precipitation, domestic sewage and industrial wastewater generated by the city, but also to create a stable and comfortable living environment for the people living in the city, maintain the ecological balance, and ensure the sustainable development of the city’s economy and environment. However, the water supply and drainage system has its own particularity. Relative measures should be taken during construction. Because most of the pipe network is buried deep underground, it is difficult to find and deal with the problems in time. Therefore, the construction management and project quality management of the water supply and drainage project need to be scientifically managed and strictly monitored.

This book will elaborate on the utilization and protection of water resources, overview of water supply and drainage project, water supply and drainage pipe network, water intake project, water conveyance and distribution project, water treatment project, sewage treatment project, and the application of BIM technology in building water supply and drainage engineering.

给排水工程在城市居民生产生活中具有重要作用，是保障城市正常运转的重要设施之一，其施工的质量与城市生活息息相关。随着城市化建设的不断推进，使得我国水资源日益紧缺，因此在给排水工程施工时一定要保证给排水工程的施工质量，保证其达到最大节水效果。给排水工程施工质量的好坏不仅影响到正常使用，更存在严重的水资源浪费现象，因此需要做好工程各方面的管理工作。给排水管道的主要作用不仅是收集并输送城市产生的降水、生活污水和工业废水，还能为生活居住在城市的人群创造一个安稳舒适的生活环境，维护生态的平衡，确保城市经济和环境的可持续发展。但是，给排水系统具有一定的特殊性。在施工时采取施工相对的措施。因其管网大部分深埋地下，管网问题难以及时发现并进行处理，因此对给排水工程施工管理与工程质量管理需要进行科学管理，严格监控其过程。

本书将对水的利用与水资源保护、给水排水工程概述、给水排水管网、取水工程、输水与配水工程、给水处理工程、污水处理工程，以及BIM技术在建筑给排水工程中的应用等方面进行阐述。

With the development of China’s economy and the increasing demand for automobiles, the automobile manufacturing industry has great potential for development, and thus it has gained bright market prospects. In this process,the development of rapid prototyping manufacturing technology for automotive parts has also revived, and has gradually become one of the most concerned technologies in the field of automobile manufacturing in China. Therefore, we need to start with its actual development process and discuss how to strengthen the application of rapid prototyping manufacturing technology in the actual automotive parts manufacturing process.

The book is divided into three sections (seven chapters). The first three chapters (the first section) respectively discuss the current situation and development trend of the automobile manufacturing industry and China’s automotive parts industry, the blank manufacturing technology of automotive parts, and the basic theory of manufacturing technology of automotive parts. The four to six chapters of (the second section) study the processing and manufacturing technology for different types of automotive parts such as shaft-like, plate-like, fork-like and box-like. The third section studies the 3D rapid prototyping technology of automotive parts and discusses rapid prototyping technology and its specific application in automotive parts manufacturing.

随着我国经济的发展，对汽车的需求不断增大，汽车制造行业具有较大地发展潜力，并因此获得广阔的市场前景，在这一过程中汽车零部件快速成型制造技术发展也焕发生机，逐渐成为我国汽车制造业领域内关注程度较高的技术之一，因而需要我们从其实际发展过程入手，对如何加强快速成型制造技术在实际汽车零部件制造过程中的应用进行有益的探讨。

本书共分为三大部分、七个章节，第一部分前三章分别探讨了汽车制造业以及中国汽车零部件行业现状与发展态势，汽车零件的毛坯制造技术，以及汽车零件的制造技术基础理论；第二部分四到六章研究轴套类、盘类、叉架与箱体类等不同类型汽车零部件的加工与制造技术，第三部分研究汽车零部件3D快速成型技术，探讨快速成型技术及其在汽车零部件制造中的具体应用。

With the development of the economy, urban construction is changing with each passing day, the requirements for the quality of construction projects and the level of safety production management are getting higher and higher. The safety production situation of China’s construction industry is grim, and the frequent occurrence of safety accidents not only brings huge economic losses to the construction enterprises and construction project owners, but also seriously affects the sustainable development of China’s construction industry, and causes many heated discussions on the topic of personal safety of construction workers.

This book is divided into eight chapters and elaborates on construction engineering, architectural design, building construction technology, construction safety hidden dangers and unsafe behaviors, safety culture construction of construction project, safety management of construction project, safety management of construction site and China’s construction safety supervision and incentive mechanism, with a view to providing a practical teaching material and reference book for the vast number of construction practitioners in China. This is our intention to write this book! As the book contains more content, involves more cumbersome knowledge, and has more compilers, the format, depth and breadth of the contents of each chapter may not be inconsistent; and the fallacies are inevitable. Readers are invited to criticize and correct. Suggestions for improvement will be gratefully received.

随着经济的发展，城市建设日新月异，对建筑工程质量的要求越来越高，对安全生产管理水平也越来越高。而我国建筑业安全生产形势严峻，安全事故的频发，不仅给施工企业和建设项目的业主带来了巨大的经济损失，严重影响了我国建筑业的持续发展，也使建筑工人人身安全这一话题引来诸多热议。

本书共分八章，从建筑工程、建筑设计、建筑施工技术、建筑施工安全隐患与不安全行为、建筑施工项目安全文化建设、建筑工程施工安全管理、施工现场安全管理以及我国建筑安全监管激励机制等方面来阐述，从而为广大建筑业从业者提供一本切合实用的教材与参考书。这也是我们编写本书的意图所在，由于本书包罗内容较广，涉及知识较烦琐，编写人员较多，各章节内容的格式、深度和广度可能并不一致，谬误无可避免，敬请读者批评指正。

The process of urbanization in China has been accelerating. While the real estate industry continues to develop, it also puts higher demands on the building. At present, China's fabricated concrete structure building has been widely used due to various characteristics such as energy saving, short construction period and easy quality control. This book analyzes the structure of prefabricated building. Through the construction technology and safety risk assessment during the construction process, the construction safety management based on this is proposed to ensure the quality of the building. To adapt the construction industry to the needs of the market, it is necessary to use new building materials and new technology. Prefabricated building can realize the componentization and industrialization of the building, which will definitely guide the development trend of the construction industry. Buildings in China are usually made on site. As a new type of building, compared with traditional construction, prefabricated building has the advantages of shortening the construction period, ensuring the quality of the project, and saving energy and reducing emissions. This book first introduces the development of prefabricated building at home and abroad. Then, the basic characteristics of the concept, characteristics and advantages of prefabricated building are introduced. thirdly, the problems of prefabricated building in China at present are analyzed. Finally, the development of prefabricated building is prospected.
