【 Weak current College 】 high-rise building water system and fire-fighting installation technology

First, in the construction industry to the drainage problems of

(A) construction and drainage construction safety management issues

Water supply and drainage construction safety management in the following issues: (1) construction of all construction units do not have to, or very little guidance to construction site inspection, causing many operations in violation; (2) supervision and inspection of the safety management of institutions construction units do not work properly, before the security education and construction safety measures are not implemented; (3) the construction unit excavation trench circuit breaker, not general contracting units ahead of escalation, contracting units cannot be under construction road layout, uniform arrangements for the time and in the same way, at the same time construction digging trench, resulted in the grace period to complete the construction and restoration of road traffic; (4) cooling tower installation not to fire prevention, construction sequence, using power tools, tools for wire insulation and safety checks, sometimes causing sparks fire; (5) General Contracting units do not have unified planning laying of temporary construction with water network, pipeline not laid in frozen line following the construction of water managers network setting fire hydrant quantity cannot be determined.

(2) water supply and drainage construction quality problems

First, the construction process of the phenomenon of rough caused, such as water seepage connection, the device installation dimensions not precise noise is too large; building materials quality customs clearance caused by the phenomenon, such as material entry not complying with the provisions in the acceptance, use, water pipes, faucets, valves close is not strict; design considerations not weeks of phenomena, such as valve insufficiency, pumping stations are considered of drainage, and so on; in architectural design, piping and equipment design and installation of the lack of precise calculations, resulting in the actual installation operation interface, equipment location, elevation, slope, position deviation, to pipeline construction matters lacked the necessary instructions, resulting in a substandard construction quality, some units to reduce construction cost, quality, and one-sided neglected works to lower cost, and cause the construction units to buy some products. Second, the construction is not normative, pipeline installation and other building construction, there are inherent in the law, this requires the construction of strictly according to the scientific program, prevent arbitrariness and blindness, as a pipe before and after the installation, if transposed, the pipeline will not enter the intended location. Third, the technology level is not up to standard, construction quality problems, due to construction technology level is not high, the quality problems caused by the large proportion of many skilled workers, at least they don't understand the construction process, the duplicating, in a line; some construction technician, no construction experience, even drawing eat impervious, dudangyimian; some supervisors untrained, even for qualification, directly affects the quality of water supply and drainage works. From the above analysis, it is not hard to see, do and drainage engineering quality, pay attention to the personnel's quality, the choice of materials for construction as per program. The main components of the core of which is to establish a good quality management system and strict management of the construction process.

2. water supply and drainage construction safety and quality management solutions

Water supply and drainage construction, safety and quality problems, solve problems, to achieve the following four areas:

1. pipe installation material quality and size standards to consolidated (1) installed to meet the water supply, drainage process construction standards, timber quality standard to unify, implementation to put in place, such as sewage, storm sewer risers should be set to check the drainage from the Center for lm floor; (2) pipe test pressure and media according to design drawings and construction specifications requirements, do not make improper changes during construction; (3) drainage pipes, manholes for irrigation test should be to ensure that implementation and smooth; 4) piping hangers installed to the pipe hangers installed standard Atlas and design and construction of concrete conditions for construction.

2. water supply and drainage, wet spraying fire engineering monitoring management: (1), submitted to audit and construction units and construction technology for construction programme of measures to assist construction units and perfect quality assurance system; (2) the professional organization of pre-construction needed Checkup, verification and civil engineering, electrical and other trouble-free; (3) the audit entry materials quality report, major equipment, accessories, product should have a date of manufacture and quality certification; (4) participation in the project quality accident's processing, organization and construction units used for transfer of construction units.

3. indoor water pipeline installation quality management: (1) hidden pipes and water supply, fire-fighting system of hydraulic test results must meet the design requirements and construction specifications and procedures for the acceptance of improperly received, consistent with the standards to eliminate risks; (2) pipe and pipe support (Pier) is laying in untreated loose Earth, because of the terrain and not a result of equipment installation and low, causing broken, damaged, etc.; (3) after the completion of the water supply system or delivery must be carried out before washing, ensure pipeline clean input use and water safety.

4. pipe accessories and sanitary ware installation and construction of water supply and accessories: quality management (1) pipeline attachment installation should pay attention to quality selection, automatic sprinkler and fire protection installations of water sprinkler head position, distance and direction must meet the design requirements and specifications for construction; (2) automatic sprinkler and fire protection equipment head-curtain should be installed in piping systems complete pressure and after washing to prevent clogging and cannot normally use, while at the same time it should be noted and civil construction and decoration of the ceiling.

Third, building drainage construction safety quality management implementation

(A) implement tracking supervision, strengthening process control

1. drainage project construction quality in every process, each sub-item project created, instead of relying on testing and assessment. Therefore, the requirements for each process are process control. Special for approaching to put to use raw materials to engineer by the scale and frequency of sampling, to determine compliance with quality requirements is allowed. Qualified material piling up at the venue should be classified, substandard materials to return.
BR > in the construction process, the track supervisors to monitor and supervise the construction contractor adheres to the implementation process before operating technology gives the low-down system, clear to all participants, construction quality requirements by the full consciousness maintenance engineering quality, improve the quality level; pay close attention to the contractor at the various stages of construction preparation before the construction quality of the impact of various factors and if there are not conducive to ensure project quality changes, as well as technology and operation is always consistent with the requirements.

3. the Director and Director of the representative to supervise professional engineers, examiners seriously implement the quality and safety inspection systems, quality control departments at least weekly for a major inspections activities, requires professional engineers every day at least 6O% of work time for on-site inspections to identify and correct the contractor's error, improper use of the materials, use of defective machinery, to order the correct it for fear of affecting the quality of the project;

4. If the contractor is in breach of contract, construction norms of behavior, such as material quality is not qualified, the application process or the operation does not meet the requirements, on-site for posts of operatives and technicians do not meet the requirement, supervisor should be dealt with in the interim. Ensure the implementation of the various systems, quality assurance system implemented. At the same time as the environment also have an impact on the quality, the supervising engineer to enhance safety, construction supervision of civilization.

(B) strict separation part of project quality assessment gateway

Sub-item project quality is forming the basis of the quality of the project is to ensure that the quality of the project, to ensure the quality of the supervising engineer to supervise and assist project managers active in workers in the quality control team activities, in accordance with the construction and installation the project quality inspection and assessment of unified standards of: sub-items, partial evaluation, the quality of the project is divided into first assessment approved two programs, quality inspection and evaluation of programs and organizations reference verification inspection process, the supervisor asked to participate in, and project quality inspection, assessment and approval process by the supervising engineer visa approved, can on quality assessment and approved effectively play a monitoring role. In addition, require approval by the data speak for measured data replace sensory impressions, make sure that each sub-item project quality are in control; if a sub-item project can not reach the intended control standards, they shall not enter into the next process to process quality and ensure project quality and safety. In this way, each key in the desired standard, each Division of the engineering-unit project will meet the standards in respect of. In addition to new materials, new processes of use evaluation to take careful attitude to increase cost, immature, or not sure would never approve the use of technology; for a change request and technology to approved, should be audited.

Water supply and drainage construction process in materials, processes, people, and other indicators are in place to ensure the safety and quality engineering. Our current due to drainage of the water supply, drainage problems confusing, causing the water resources of the rational use of water problems, has been a growing concern, the water supply and drainage construction process, strengthening of water supply, sewerage construction management, and improving technological level, to ensure the quality of the project, so that their production, energy security, increase economic efficiency, ensure the safety and quality is vital, this can reduce the emergence of the waste of water resources, in line with the social and economic development needs, to optimize the allocation of water resources, ensuring safe water, drainage, can improve environmental management standards, ensuring sustainable economic development in China.
