As an important basic industry of national economy, transportation is an important chain of social circulation and distribution, which plays an important supporting and guarantee role in social economy and national defense construction. In the four transportation systems of railway, civil aviation, water and highway, highway transportation, as the continuation of social production process in the field of circulation, plays an extremely important role. With the rapid development of national economy and the fierce competition of industry division, road transportation is required to be further high-speed and networked, improve transportation efficiency and reduce transportation costs, which set off a large-scale highway construction investment in recent years. Because the construction of highway engineering is different from other types of construction, its characteristics of large investment funds, long construction period and wide influence are all thorny problems. Therefore, we put forward more difficult and higher requirements for highway construction management than general engineering management. For any project, the excellence of its management system determines the quality of the project. In the
management, strict control of every link of the project construction process is also an essential means of high-quality highway construction.
This book expounds the relevant contents of highway construction management from two aspects of highway construction and highway construction management. Highway construction is divided into three parts: highway planning and design, highway construction and highway maintenance. Highway construction management includes cost management, schedule management, safety management, quality management and other management contents.
In the aspect of highway construction, the book details the plane design, vertical section design, intersection design, subgrade design, pavement design, highway drainage and landscape design, construction preparation of highway construction, highway site construction technology, mechanized construction, subgrade maintenance, pavement maintenance, bridge and culvert, highway damage type in highway design. This book is designed to provide scientific and rigorous theoretical support and help for highway construction practitioners in China.
The management of highway construction runs through the beginning and end of highway project construction. Whether it is the preparation of materials and funds in the early stage, the cost, progress, safety control in the construction, or the quality monitoring and testing of the project, it plays an extremely important role in the process of highway construction. Only by carefully and carefully doing everything in the management process, coupled with the standardized management system and the current relaxed industry environment, China’s road construction management work will be able to thrive and contribute to the sustainable development of China’s economy.
Our intention of compiling Construction and Management of Highway Engineering is to provide a practical textbook and reference book for highway construction practitioners. However, because the book covers a wide range of contents, involves a lot of knowledge, and is written by many people, the format, depth and breadth of the contents of each chapter may not be the same, and fallacies are inevitable. Readers are welcome to criticize and correct them.
China has a large population, and the total amount of housing construction is also in the forefront of the world. With the continuous improvement of people’s living standards and the continuous development of economic level, people’s demand for housing construction is also increasing, and the country’s requirements for the quality of housing construction are higher and higher. In order to meet the national construction requirements and the people’s living needs, it is necessary to improve the quality and progress of housing construction, and carry out a comprehensive analysis and research on the design, construction technology and construction management of housing construction, so as to improve the construction technology and management level of housing construction in China.
This book has made a full study on the construction technology and management of housing construction in China from many perspectives, including the concept and elements of housing construction in China at present; the main contents and design procedures of housing design in China; the research on the common building structure system of housing construction; the analysis on the main structure of housing construction; the analysis of the organization management, construction procedure and construction technology in the process of housing construction; the organization design scheme in the process of housing construction; the project quality management in the process of housing construction and the handling method of unexpected accidents; the safety management and environmental management during the construction of housing construction.
With the social development and population growth, the status of water conservancyis becoming more and more important. In recent years, China has increased investment ininfrastructure construction of water conservancy projects. Water conservancy project has entered an unprecedented stage of development. However, the construction of water conservancy project is a huge and complex system engineering. The quality management and control of water conservancy project run through the whole construction process. In the construction of water conservancy projects, the topography, geological conditions, hydrological conditions and environmental climate of the construction site should be observed first. These conditions are important factors affecting the construction of water
conservancy projects and play an important role in their quality. In the process of construction, water conservancy project managers should deal with the relationship between various factors to ensure the normal and smooth implementation of water conservancy projects. Good management of water conservancy projects is an effective guarantee to improve economic and social benefits, and also a prerequisite to achieve the goal of sustainable development of water conservancy projects.
This book mainly elaborates the modern water conservancy project managementfrom the content of ten chapters, hoping to contribute to the project promotion and progress of relevant staff。
In recent years, with the progress of the times and the rapid development of social economy, human beings need more and more resources. The lack and waste of resources is also an important problem now. Water is the source of life and the basis of human survival. The protection and conservation of water resources should be valued by all
people. Therefore, we should improve the comprehensive utilization efficiency of water resources, actively publicize the saving information of water resources, and let the masses start from small things. For urban water supply, we should plan more intensive programs, make management information open and transparent, and promote sustainable development of water resources.
This paper first expounds the basic concept of water resources, including how water resources are formed, then describes how groundwater and surface water are developed and utilized, as well as the selection and layout of its projects, and expounds the importance and measures of sustainable development of water resources; this paper puts
forward several measures for the protection of water resources, expounds how to use new technology to save water more, how to plan urban-rural integrated water supply, what are the influencing factors of urban integrated water supply planning, and how to establish urban-rural integrated water supply management system; finally, the design of water resource management information and transmission system is described. The author hopes to provide readers with some reference opinions, and contributes to the protection and conservation of water resources, so as to promote the sustainable development of water resources
The development of green circular modern agriculture is an important basis for adhering to people-oriented, comprehensive, coordinated and sustainable development, an important measure for building a harmonious society, an important content for building a resource-saving and environment-friendly society, an important way to realize the rejuvenation of agriculture through science and education and the construction of an innovative country, and an important guarantee for building a well-off society and a new socialist countryside in an all-round way.
Agricultural mechanization is an important part of agricultural engineering and an important symbol of agricultural modernization. Without agricultural mechanization, therecan be no agricultural modernization. To realize agricultural mechanization is to equip agriculture with all kinds of power machinery and its supporting operating machinery in agricultural production, to combine mechanical engineering technology with advanced agricultural technology and scientific management of agricultural system, to serve the agricultural production process, to greatly improve agricultural labor productivity, cost saving and efficiency, and to improve resource utilization; the realization of agricultural mechanization requires not only the availability of suitable machinery technically, but also the social and economic conditions for the use of machinery. Agricultural mechanization involves the mechanization of planting, animal husbandry, forestry, rural industry and sideline and fishery, and its service field will expand with the adjustment of agricultural industrial structure and the development of production. Agricultural mechanization engineering technology will provide methods, means, management and services for the gradual realization of machine operation in all links of agricultural production process, including the design, research and development of various agricultural machinery, equipment and facilities, and the design, implementation and operation of various agricultural mechanization schemes. Agricultural mechanization engineering technology is not machinery, but the combination of agricultural machinery and agronomy, technology and economy, technology and management.
