With the development of social economy, the urbanization process has been further accelerated, which has promoted the development of China's construction industry. However, in the process of water supply and drainage construction of high-rise buildings at this stage, it is easy to be influenced by other objective factors, which makes the construction quality difficult to meet the requirements of high-rise buildings. Therefore, in the process of high-rise building construction, the corresponding construction units are required to make scientific and reasonable analysis in combination with the construction requirements, strengthen the design of water supply and drainage system, select appropriate construction raw materials, and effectively improve the quality of water supply and drainage construction of high-rise buildings on the basis of ensuring its construction technology.
1 construction points of water supply and drainage system of high-rise building
The water supply and drainage system of high-rise buildings can be divided into water supply system and drainage system. In order to ensure that the water supply and drainage system of high-rise buildings can operate stably and meet the needs of residents, the characteristics of high-rise buildings should be considered in the design process, and the work of earthquake resistance, settlement prevention, noise prevention and leakage prevention should be strengthened. At the same time, it is also necessary to ensure that the water pressure of the fire protection system can meet the needs of high-rise buildings. If the water demand of high-rise residents cannot be met, secondary water supply with intermediate pressure is needed, thus increasing the load of the pipeline and shortening the service life of the water supply and drainage pipeline and its components [1]. Therefore, in the design process of high-rise building water supply and drainage system, the corresponding staff should be able to choose the water supply mode scientifically and reasonably according to the specific situation, so as to reduce the water pressure and ensure the stability of high-rise building water supply and drainage system. At the same time, in order to reduce the adverse effects of natural disasters such as fire on high-rise buildings, in the design process of high-rise buildings, it is necessary to set up a reliable indoor fire water supply system and strengthen the performance of materials and equipment used in buildings.
2 Analysis of technical characteristics of water supply and drainage construction
2. 1 water supply pipeline construction. In order to ensure that the water supply and drainage system can meet the needs of high-rise buildings and stabilize the pressure in drainage pipes, it is necessary to reserve a certain space for the laying of water supply risers and drainage risers in the process of laying water supply risers in high-rise buildings. In the process of selecting water pipes, the quality and vertical static pressure of water pipes should be fully considered. In the process of installing the drainage pipeline, it is necessary to strengthen the vertical segmentation according to the needs of residents and divide the vertical pipeline into multiple areas to reduce the static pressure of the pipeline and effectively extend the service life of the pipeline. Starting from the basement, the water supply pipes will be laid and fixed in an orderly manner. In order to effectively guarantee the residents' experience, in the process of water supply pipeline construction, the later inspection and maintenance work should be fully considered. In the process of laying horizontal water supply pipes, various methods can be adopted, and the corresponding materials and space positions can be selected to effectively ensure the laying quality and effect of horizontal water supply pipes.
This requires the corresponding staff to choose the appropriate construction technology in combination with the use requirements of high-rise buildings to effectively ensure the stability of the water supply system of high-rise buildings. In the process of laying horizontal water supply pipes in high-rise buildings, horizontal water supply pipes can be laid in the ceiling, which can effectively protect the integrity of wallboard and facilitate construction and maintenance. In the process of laying indoor pipes, the structural flat plate can be slotted according to the specifications of the pipes, and the other half of the pipes can be embedded and fixed. In addition, the pipeline can also be laid in the non-bearing wall, and the pipe groove can be dug according to the design requirements. In the process of water supply pipeline construction, in order to effectively prevent water leakage, in addition to the corresponding waterproof work in the construction process, the wall surface can also be marked for later maintenance and repair.
2.2 Drainage pipeline construction. Due to the high floors of high-rise buildings, many residential users and large displacement in daily life, the pressure on drainage pipes has increased. In order to effectively ensure the stability of the drainage system of high-rise buildings, in the construction process, it is necessary to fully consider the adverse effects of various factors on the drainage pipeline, comprehensively utilize various drainage methods, effectively reduce the pipeline pressure, and continuously strengthen the stability and safety of the drainage system. In the process of laying drainage pipes, firstly, through scientific and reasonable design, fully consider the water demand of residents, choose appropriate drainage methods, and effectively strengthen different drainage work such as domestic drainage and rainwater diversion drainage. In the drainage system of modern high-rise buildings in China, UPVC pipes are often used instead of traditional plastic pipes. In fact, this kind of drainage pipe is noisy and has poor sound insulation effect, which will affect the comfort of high-rise buildings to a certain extent and it is difficult to meet the needs of users.
Therefore, in the process of laying drainage pipes in high-rise buildings, we should first consider the influence of building materials on the drainage system of high-rise buildings, select pipes with high mechanical strength, and strengthen the treatment of their flexible interfaces, so as to effectively improve the stability of the drainage system and effectively avoid blockage [2]. In the process of laying the drainage system of high-rise buildings, it can be effectively distinguished according to its use function, and the rainwater with large displacement and the floors with small displacement can be layered to effectively ensure the construction quality of drainage pipes. You can also set up an independent drainage system to collect rainwater and use it as irrigation water for residential areas after softening, thus effectively improving the utilization rate of water resources. In order to effectively strengthen environmental construction, we can also ignore the sewage of high-rise buildings, which can effectively avoid the overflow phenomenon due to excessive pressure and effectively strengthen the living environment construction of low-rise users. At the same time, in the process of laying drainage riser, considering the future maintenance, corresponding inspection ports can be set above the roof foundation and window sill to facilitate maintenance. In the process of laying horizontal drainage pipes, the aesthetics and drainage function of the building are considered as a whole, and various ways such as rear outlet type and side wall type can be adopted to effectively strengthen the laying of horizontal drainage pipes for toilets and floor drains, and effectively keep the building indoor clean and tidy.
3 Conclusion
In a word, the layout effect of water supply and drainage system in high-rise buildings directly affects the quality of life of residents. Therefore, in the construction process of water supply and drainage system in high-rise buildings, scientific and reasonable design should be adopted to effectively ensure the stability of water supply and drainage system, and corresponding inspection mechanism should be established to continuously improve the construction quality of water supply and drainage system in high-rise buildings. At the same time, in the construction process of water supply and drainage system of high-rise buildings, the corresponding staff are required to strengthen their understanding of water supply and drainage system of high-rise buildings, set corresponding expansion joints in strict accordance with the construction requirements, select appropriate water supply and drainage materials and pipelines, strengthen periodic inspection, strictly implement the concealed acceptance system, and create a good living environment for users.
