Preface

Roads, bridges, water conservancy, industrial and civil buildings are all civil engineering. Civil engineering construction is the basic construction of national economy, which plays an important role in the development of national economy.

  The project construction includes several stages of survey, planning, design and construction. Among them, the construction stage is the stage of turning the design into a real object, which is a very important stage of engineering construction management. Our country adopts the contract system. In order to complete the project tasks and obtain more profits according to the construction period, quality and cost stipulated in the contract, the contractor must carry out effective construction management in addition to relying on skilled construction team and advanced construction equipment. Management can not replace technology, but management is technology management, so we should attach great importance to management.

  The mechanization of highway and bridge engineering construction refers to that in the construction process of the whole project, the mechanical equipment and machines and tools used in each process are integrated and connected in sequence according to the construction process, and the construction is reasonably organized, so as to seek the fastest progress of the project, the best quality, the best mechanical performance and function, so as to achieve the highest economic and social benefits of the project. The quality of the project not only reflects the level of technical equipment, but also reflects the quality of construction personnel. In the past, the management cadres and operators in our technical team did not understand the machinery, and those who engaged in machinery did not understand the project, which brought difficulties to the construction mechanization, and even affected the progress and quality of the project. This situation needs to be reversed, so we must pay attention to the training of construction management personnel, technical personnel and operators as soon as possible in the construction, so that the designers, constructors, executors and operators of mechanized construction can cooperate scientifically.

前 言

道路、桥梁、水利、工业与民用建筑等均属于土木工程。土木工程建设多是国民经济的基础建设，对国民经济的发展具有重要的作用。
       工程建设包括勘测、规划、设计、施工几个阶段。其中施工阶段是将设计变成实物的阶段，是工程建设管理极为重要的阶段。我国工程采用承包制，承包者为了按合同规定的工期、工程质量和工程成本完成工程任务并获得更多的利润，除了靠具有精湛技术的施工队伍和先进的施工设备之外，还必须进行有效的施工管理。管理不能替代技术，但管理是管技术的，因而应高度重视管理。
       公路和桥梁工程施工机械化是指在整个工程项目的施工过程中，按照施工工艺流程，把各个工艺使用的机械设备和机具综合配套、顺序衔接，合理地组织施工，以谋求工程进度最快、质量最好、机械性能和作用发挥最佳，使经济效益和社会效益均取得最高的项目效果。工程质量的好坏，不仅反映技术装备水平的高低，同时也反映施工人员的素质。以前我们的技术队伍中管理干部和操作人员，搞工程的不懂机械，搞机械的不懂工程，这些都给施工机械化带来困难，甚至影响到工程进展和施工质量，这种状况需要扭转，所以在进行施工时必须及早抓好施工管理人员、技术人员及操作人员的培训工作， 使机械化施工的设计者、 施工者和任务的执行者、操作人员，能科学地配合。
