Problems and quality control measures in fire engineering construction?

Nowadays, China's economic development level is increasing day by day, the development degree of the construction field is getting faster and faster, and people's requirements for construction are getting higher and higher. The increasingly complex structure and huge volume of modern buildings have brought certain difficulties to the construction of fire fighting projects. After the building is completed, the amount of fire fighting works is huge, and a series of changes put forward higher requirements for the safety of building fire fighting works. In the process of fire engineering construction, we should comprehensively sum up previous work experience and combine our own work level to effectively improve the safety of fire engineering and promote the healthy and stable development of fire engineering industry.

In recent years, with the continuous progress of society, people's quality of life is improving day by day, and the demand for construction projects is increasing. At the same time, the structure of the building is becoming more and more complex, and the coverage of the fire protection system is also increasing, so the fire safety and fire resistance of the building are becoming more and more important. Therefore, in the process of fire engineering construction, while paying attention to engineering design and material selection, we should maximize the construction quality and ensure the safety of the project. Below, this paper discusses the common problems and quality control measures in fire engineering construction in detail.

1 fire engineering construction analysis

From the construction content of building fire protection engineering, the construction content of fire protection engineering is very complicated and involves a wide range, among which fire hydrant system, water supply system, mechanical system and detection sensor alarm system are all important contents in fire protection engineering construction, and all systems are interrelated. Therefore, in the process of construction, we should pay full attention to the establishment of various systems to fully reflect the integrity and comprehensiveness of fire engineering construction. Judging from the characteristics of building fire engineering construction, fire engineering construction mainly embodies the following four characteristics: First, it has a strong purpose. Building fire safety is the basis of fire engineering construction. The establishment of fire-fighting facilities provides a solid guarantee for the fire-fighting performance and safety performance of buildings. Second, it covers a wide range. There is a close relationship between fire engineering construction and building construction. Problems or operational errors in one link will threaten the safety performance of the whole building.

Third, the construction period is long. In the construction of fire fighting engineering, there are many cross operations, and the construction site is easily affected by many factors, and the situation on the spot is quite unstable. Fourth, the quality requirements for fire engineering are very high. If there is a problem with the quality of fire fighting engineering, it is difficult to give full play to its fire fighting performance. Once a fire breaks out, it will do great harm and pose a serious threat to people's life safety and property safety. Judging from the development of building fire protection engineering, with the continuous advancement of urbanization, China's construction industry has achieved rapid development, the construction scale is expanding day by day, and the number of buildings is increasing. The scientific construction of building fire engineering directly affects the overall safety of the building, which puts forward higher requirements for the construction level of fire engineering construction units. Under the traditional fire engineering construction mode, there are many problems that affect the safety of fire engineering. Therefore, modern fire engineering construction should strengthen the innovation of management mode, improve the safety construction efficiency while ensuring the construction quality, and then promote the healthy, stable and sustainable development of building fire construction.

2 common problems in fire engineering construction

2. 1 fire engineering construction design problems

Construction design is an important part of the whole fire protection project, which has a key impact on the later construction. As far as the construction design of fire protection engineering is concerned, there are two main problems: first, the fire protection engineering design unit does not strictly abide by the national fire protection laws and regulations, and the construction design drawings do not meet the fire safety requirements, which leads to many technical problems that are difficult to solve in the fire protection construction process; Secondly, because some fire engineering designers lack construction experience and their qualifications are not enough, the designed fire construction design drawings are different from the actual construction site, which not only brings technical obstacles to the construction, but also affects the fire construction process.

2.2 Problems existing in fire hydrant system

A, fire hydrant installation does not conform to the requirements of the specification. During installation, the lintel was not installed above the fire hydrant box hole of some brick walls, which led to the deformation of the box body under heavy pressure and affected the door switch. In addition, the reserved holes at the bottom of fire hydrant box are randomly located, and most of the reserved holes are cut by gas welding. After installation, the outlet of the fire hydrant is not perpendicular to the wall where the fire hydrant is located, or the distance around the fire hydrant is small, which affects the normal installation of the fire hose, or causes the hose to bend, resulting in too small water output. For buildings with complex structure and large area, we usually only pay attention to the water pressure demand of fire hydrants in ordinary locations, while ignoring the water pressure demand of other complex fire safety hazards. Secondly, the installation of underground water pump adapter and underground outdoor fire hydrant is not strictly in accordance with the requirements of standard atlas.

2.3 problems existing in automatic sprinkler system

First, the distance between the system nozzle and the surrounding objects is too small to protect the system nozzle in case of fire. In addition, because the nozzle of the system is far away from the ground, the role of its temperature sensing element can not be effectively played, which affects the spraying effect. Secondly, in the construction, in order to pursue beauty or convenience, no effective measures were taken to protect the system nozzle when painting decorative coatings, so that it was covered with paint. Once a fire breaks out, the sensing ability of the temperature sensing element of the system nozzle is affected, and it can't respond in time, which affects the fire safety. Thirdly, due to the limitation of the site, many automatic sprinkler systems are not equipped with terminal water testing devices or installed in public places, and floor drains and drainage pipes cannot be installed in public places. Once the equipment fails, the fire-fighting water in the system cannot be discharged, which affects the normal use of fire-fighting facilities. Fourthly, in the management of fire safety system, the hydraulic alarm bell should be installed in the unattended position, but as far as the actual situation is concerned, the hydraulic alarm bell is often installed in the unattended position such as pipeline wells and pump houses, which leads to the failure to give full play to the early warning function of the hydraulic alarm bell.

3 fire engineering construction quality control measures

3. 1 Strengthen the control of construction design.

The scientificity of fire engineering design has an important influence on the layout and construction effect of the whole fire engineering. Therefore, in order to promote the smooth implementation of fire protection engineering and ensure the fire protection function of fire protection engineering, it is necessary to strengthen the control of construction design stage. The specific measures are as follows: First, strictly examine the qualification of the design unit, and comprehensively consider its design experience, design quality, design certificate and design qualification to ensure the scientificity of the construction design scheme. Second, strictly follow the construction process, strengthen the design behavior audit, improve the fire design responsibility system, and realize the dynamic management of fire engineering design.

3.2 Establish a strong sense of quality management

In the process of fire engineering construction, the construction quality should be controlled from the perspective of whole process management. Establish a refined management concept, strengthen the connection between building engineering and fire engineering, and incorporate all elements of fire engineering construction into management planning to ensure the quality of fire engineering. On the one hand, it is necessary to strengthen the concept of whole-process engineering management, comprehensively summarize the problems and defects existing in fire engineering construction, actively explore new management methods, and bring them into the whole-process management of fire engineering construction; On the other hand, according to the different working procedures of fire engineering, the project construction scheme is scientifically formulated, and based on this, all links are ensured to proceed smoothly. In addition, in the fire engineering construction, attention should be paid to the construction quality inspection, so that the work function of the quality supervision department can be effectively played. Once construction defects or quality problems are found, they should be rectified immediately to ensure quality.

3.3 Strengthen the scientific management of construction personnel

In the process of fire engineering construction, as a dynamic factor, fire construction personnel have a key impact on the overall quality of fire engineering. Therefore, in order to improve the construction quality of fire fighting projects, it is necessary to strengthen the scientific management of construction personnel. First of all, strengthen the qualification audit of construction personnel, require all construction personnel to hold certificates, organize construction personnel to learn the quality management system of construction projects, cultivate their awareness of engineering norms, and actively participate in the quality control of fire control construction. Secondly, strengthen the technical training of fire fighting construction for construction personnel, organize them to actively learn the legal knowledge of fire fighting construction, improve the professional level of construction personnel and enhance their comprehensive quality. Finally, improve the management of construction equipment, provide scientific construction equipment for construction personnel, create a good construction environment for them, and make them devote themselves to the fire protection project construction with higher enthusiasm.

3.4 Strengthen the inspection and management of the construction site

In order to improve the construction quality of building fire protection engineering, it is necessary to strengthen the management and inspection of the construction site, strictly abide by the fire protection laws and regulations, and once the building structure or fire protection facilities are found not to meet the standard requirements, the construction unit should be ordered to immediately rectify, and the construction unit that fails to rectify within the time limit should be severely punished and ordered to stop work for rectification. For the project accepted by the fire supervision department, it is necessary to strengthen the management and inspection of fire-fighting equipment, and immediately repair the fire-fighting facilities with quality problems or defects to ensure that there will be no quality problems during use.

3.5 Strengthen the strict control of the construction process.

First, strengthen the overall control of fire engineering construction. Led by the competent government departments, strengthen the control of fire engineering design and planning, and set up a special inspection team to supervise and manage the behaviors of supervision units and construction units. Second, the supervision unit should fully control the construction quality in strict accordance with the supervision contract and supervision measures. In the construction of fire control project, the supervision unit has the right to supervise, and the construction quality can be guaranteed through the independent supervision of the design unit and the construction unit. Third, the construction unit should strictly follow the construction quality requirements and strengthen quality control. Based on the construction contract, strengthen the implementation effect of management responsibility, set up a construction quality self-inspection team, supervise the whole construction process, strengthen cooperation with government departments and supervision units, and ensure the construction quality.
