Therefore, to correctly handle the relationship between construction safety and

2、 quality management plays an important role in the smooth completion of engineering projects and the stable development of society.工程质量是施工企业的生命,它反映整个企业的技术水平与管理水平。工程施工质量管理乃是确保工程质量的关键,按照设计文件和技术标准规范,采取正确的施工方案,合理组织施工是确保施工质量的依据。在工程进度与质量发生矛盾时,必须坚持质量第一的原则。严格落实各项质量管理制度和措施,明确责任,真正做到质量人人有责,任何质量工作均有对应的标准和专人管理。

3、Keywords: construction; safety; factors; measures1. Instruction: Project quality is the life of the construction enterprise, which reflects the technical level and management level of the whole enterprise. Engineering construction quality management is to ensure that the key to the engineering quali

4、ty, according to the design documents and technical standards and specifications, adopt the right construction scheme, the basis of a reasonable organization construction is to ensure the construction quality. When there is a conflict between project progress and quality, we must adhere to the princ

5、iple of quality first. We will strictly implement various quality management systems and measures, clarify responsibilities, and truly hold everyone responsible for quality1.1Aim and objectiveSimply and obviously, the quality and safety control in order to ensure the quality, in order not to appear

6、to cut corners in building the existence of potential safety problems, the significance of the quality and safety control is to guarantee the building to use fixed number of years, avoiding because of the error of construction quality and make the building and safety factors2. quality effecting fact

7、orsThe five factors influencing the quality of the people, methods, machines, materials, and environmental factors and the whole process of engineering construction each phase, the bidding signing stage, construction stage, construction stage and completion stage of control management, to achieve th

8、e objective of the whole project quality control.2.1.One persons factor determines the qualityAs one of the subjects of engineering construction, decision makers, managers, conductors and construction operators are the first factors that affect the quality of engineering. Especially the business lea

9、ders do not pay attention to everything. In engineering construction, people are taken as the object of control to avoid mistakes. Taking people as the driving force of control is to fully mobilize peoples enthusiasm and play the leading role of human factor first. The quality of personnel will dire

10、ctly and indirectly affect the quality of construction. For example, it is an important management measure to ensure the quality of personnel to strictly implement the management of business qualification and the certification system for all kinds of professional employees. Extensive quality publici

11、ty education. Using the picture album, banners, leaflets and other forms, the propaganda quality objectives, quality and safety, quality, etc, the significance of the relationship between the workers and managers can remember the slogan of one hundred plan, quality the first, quality consciousness t

12、o thorough popular feeling.In a word, no matter how much and how complete the quality system is, it still depends on peoples consciousness, especially the consciousness of the upper management2.2Methods determine qualityMethods: it refers to the technical scheme, construction technology, organizatio

13、n measures, inspection means and construction organization design adopted during the construction period of the project. The construction scheme is the source of all projects. Whether the scheme is correct or not will directly influence whether the three goals (progress, quality and investment) of t

14、he project can be achieved smoothly. Therefore, in the formulation and audit the construction plan, combined with the actual situation of this project is to conduct a comprehensive system analysis, comprehensive consideration, so that to improve quality, speed up the construction schedule and reduce

15、 the construction cost.Engineering construction is a complex production process, and technology has a significant impact on quality. For example, the connection of rebar, there was lap joint before, and then there was welding and mechanical connection, which greatly improved the construction quality

16、. Combining the reality of each project, from technology, organization, management, process operation, economy and so on to conduct a comprehensive analysis, vigorously promote the adoption of new technologies, new techniques, new methods, continuously improve the level of technology, is an importan

17、t factor to guarantee the stability of the engineering quality improving2.3Construction machinery and construction machines affect project qualityThe construction of mechanical equipment will have a direct and important impact on the construction progress and construction quality of the project, bec

18、ause mechanical equipment is an important material basis for realizing the construction mechanization of the project. In the project construction phase, on the basis of considering the condition of construction site, must consider building structure system, mechanical equipment, construction organiz

20、ts of large scale, new technology, high precision, must rely on advanced construction machinery is possible, some engineering projects with the aid of specialized equipment, its hard to do and carry out the job, not to mention quality assurance2.4Factors of materials affect the quality of engineerin

21、gMaterials refer to the raw materials, finished products, semi-finished products, components, etc. Engineering characteristic is: the process will be covered by the next working procedure, in which the quality problem of the hard to find, if the quality problem to show, it tends to be more severe an

22、d difficult to remedy, or produce cost. Engineering materials will directly affect the structural stiffness and strength of the construction project, affect the appearance and appearance of the project, affect the function of the project, and affect the safety of the project. Firstly, select the man

23、ufacturer and supplier with good quality, low price and high reputation; Secondly, we should strengthen the inspection and acceptance of materials, and strictly check the entrance inspection and on-site witness sampling for inspection. In addition, the quality of some construction machines and tools

24、 has a direct impact on cost control. For example, the quality of the template is not only related to the appearance of concrete, but also related to the turnover rate. Proper and reasonable use of materials, avoiding one-sided and extreme pursuit of economic benefits, and resolutely avoiding the us

25、e of unqualified materials in engineering construction2.5Environmental factors affect project qualityEnvironmental factors is also an important factor affecting the quality of engineering, environmental factors affecting the quality of engineering in the construction of more, generally can be divide

26、d into engineering environment, engineering management three aspects, such as environment and work environment.Environmental factors is not immutable, but there are variety, different projects will have different engineering environment, management environment and working environment, and the same p

27、roject, at different times, environmental factors also changes, such as meteorological conditions, in one day, such as temperature, humidity, wind and rain are change, and the changes will have influence the quality of engineering. Therefore, according to the specific characteristics and conditions

28、of the project, the environmental factors affecting the quality should be considered comprehensively, and effective measures should be taken to strictly control these factors.3. Problems in constructionProblems in quality management of construction1.1.1 Insufficient implementation of relevant laws a

29、nd regulations, although our country launched a building law as the specification of the construction industry, however, there are a lot of local government departments and construction enterprises lack of implement and in-depth implementation of the principles, occasionally lead to manipulation phe
