Construction of water conservancy common quality problems and control measures

Abstract: The construction quality is the enterprise survival and development of the fundamental, is the enterprise in the fierce market competition to win the key to development. In the modern water conservancy construction, the construction enterprises of common quality problems can effectively protect the prevention and control of construction quality, reduce the cost of quality defects governance for development of enterprises laid a good foundation. In this paper, water conservancy construction in the common quality problems and control measures are briefly discussed.

Keywords: Engineering, construction, quality problems, control measures

0 Introduction
Construction of water conservancy construction in modern, enterprise level quality control and management of the development of enterprises in key industries. How common for water conservancy construction quality control has become the pre-modern water conservancy construction enterprises are facing the most important issue. For this problem, more and more construction companies began to strengthen their own quality management system, enhance their level of construction quality control, as the development of enterprises laid a solid management foundation. scientific analysis of the water conservancy construction of the common quality problems, characteristics for its pre-control measures related to water conservancy construction enterprises has become an important modern work.

1 Overview of Water Quality Problems
At present, China's water conservancy construction in the common quality problems mainly concentrated in the "invisible subcontracting" caused by quality problems, caused by the rush to finish the work schedule is not complete process of construction and related problems of some aspects of technical quality. "Invisible subcontract" makes the construction process, quality control and supervision decreased, resulting in the construction quality of the enterprise after contracting problems. rush to finish the work schedule makes the construction process, resulting in concrete time period of consolidation, conservation occurs not in place and other circumstances. In addition, technical supervision of the construction process and management is not in place due to quality problems have also occurred. for such a situation, enhance their quality of supervision and management, improve quality control as an effective quality control of the key water conservancy construction.

2 hydraulic control of the construction of common quality problems
2.1 improve the construction quality control system, and improving ability to improve the construction quality control quality control system, enhancing the subcontracting, subcontracting the quality of supervision is an effective water conservancy project construction to avoid quality problems of important ways. In the modern water conservancy construction, the construction enterprises should strengthen its quality control system to establish and build the actual situation for project quality control system, effectively improve the business and supervision of construction quality control, prevention of common quality problems.

2.2 The progress of scientific planning period to reduce the duration of contraction caused by quality problems in modern water conservancy construction, due to advance planning on the location of the project is unreasonable or inadequate climatic conditions often result in estimated duration of tense situation. Enterprises in order to complete the project within the specified time, reduce business costs due to schedule delays, and its construction will be shortened in the construction time of each process. For example: cement concrete pouring speed, shorten the consolidation time after pouring, curing time is inadequate. These issues will affect the concrete strength, even lead to concrete cracking, and its serious impact on the water conservancy project in the dam's safety.

For such cases, the modern water conservancy construction enterprises in the project cost should be considered the preparation stage of the construction period the impact of scientific planning and construction period, the duration of the various factors that may affect the analysis, in order to ensure the duration of the rational, scientific, To avoid problems caused by the quality of the hidden period basis.

2.3 The focus on management of water conservancy construction technology to avoid the quality problems of construction technology is an important factor in the quality of water conservancy construction, the water conservancy construction of modern enterprise management focus. In water conservancy construction process, construction enterprises through improved technology Management System guidance technology management, effective protection of the construction process of the technical parameters of the design requirements, protection of construction quality. in the field management, the water conservancy construction enterprises should strengthen field surveillance, strengthen the technical and quality personnel inspection work, improve the technical control effects, in order to avoid the construction quality problems. reposted elsewhere in the Research Papers Download http://www.hi138.com 3 to the quality of pre-control theory of common quality problems in construction to prevent hydraulic
In the modern water conservancy construction, more and more enterprises begin to pre-control theory to guide the quality of management. The impact of water conservancy project on the factors that control the construction quality to achieve the purpose of prevention of quality problems. According to this theory, modern Engineering construction company before construction that should technical documentation on the project, geographical conditions, geological conditions such as a comprehensive analysis and feasibility studies, various factors will affect the project for statistical and classification, production quality control point of library science. In The actual construction process, hydraulic technicians and quality managers in accordance with the related quality control point library control, water conservancy construction in order to prevent the occurrence of quality problems. In addition, for construction materials, construction equipment, personnel and technology, on-site management and so on, the construction enterprises should establish sub-control system, and strengthen the control of various factors, avoid construction quality problems.

4 strengthen personnel training and management, effectively prevent the occurrence of water conservancy construction quality problems
Man, water conservancy construction management in the first element of the work carried out to serve the people-based work, human factors that affect the quality of water conservancy construction of intelligent and more to factors. In hydraulic Engineering construction quality control and management, Construction enterprises should strengthen the training of relevant personnel, to improve the quality of construction workers sense to effectively prevent the occurrence of water conservancy construction quality basis. Meanwhile, the construction enterprises should enhance the quality of personnel management and accountability related to the improvement of the construction workers , technical staff, quality management personnel to clear the quality of their responsibilities, authorities, and through training to specific elements of construction quality control, improve construction quality awareness for the prevention of quality problems at the same time lay the foundation for the occurrence.

5 Conclusion
In summary, the water conservancy construction quality management work requires a corresponding investment in enterprises based on their relevant management system to accelerate construction, improve quality control standards. Also by the quality of pre-control theory of the construction of water conservancy control factors to achieve the purpose of preventing quality problems. In addition, the construction enterprises should strengthen their common problem of quality control technology level, in the event of quality problems can have technical staff when scientific management measures proposed to ensure construction quality, protect the safety of hydraulic Engineering. through quality management work for the healthy development of enterprises, raising the level of integrated management of solid foundation.
