In recent years, the installation technology requirements of building electromechanical engineering have become more and more strict, especially the layout of various pipelines, which must be constructed in accordance with strict specifications. This paper expounds the comprehensive balance technology of pipeline layout, and analyzes and discusses the application strategy of this technology in building electromechanical engineering.

1 preface

There are many mechanical and electrical engineering projects, mechanical and electrical equipment and complicated pipelines. Cross construction of various pipelines will easily lead to chaos in the construction site. Therefore, it is of great significance to strengthen the comprehensive layout of electromechanical engineering pipelines. The comprehensive balance technology of pipeline layout is a management technology applied to building construction, which is mainly applied to the mechanical and electrical installation of buildings, involving pipeline installation in ventilation, air conditioning, water supply and drainage, electrical and intelligent control. , and can comprehensively arrange the professional pipelines to ensure that the pipelines do not affect each other. The comprehensive balance technology of pipeline layout is to use computer technology to simulate the actual situation of the project, and then complete the pre-assembly of various pipelines on the drawings. Through computer technology, the construction site can be simulated, thus reflecting the problems existing in the construction site, solving the problems of mismatched, uncoordinated and unbalanced pipeline installation before construction, and reducing the rework rate. The application of this technology in building electromechanical engineering projects is of great significance, which can shorten the construction period and avoid the overlap of electromechanical engineering pipelines, thus improving the quality of engineering construction.

2 Overview of balance technology of pipeline comprehensive layout

2. 1 technical definition of comprehensive balance of pipeline layout

The comprehensive balance technology of pipeline layout is mainly used in the installation, construction and management of building electromechanical engineering. Using CAD technology and computer technology to design and simulate the installation project of building mechanical and electrical engineering, find out the possible problems in the installation process of mechanical and electrical equipment pipeline, and then adjust the pipeline installation scheme to achieve satisfactory construction effect with minimum cost. For some large buildings and high-rise buildings, there are many electromechanical engineering pipelines with high integration. In order to ensure the timely completion of the construction period and prevent the delay of the construction period, the comprehensive balance technology of pipeline layout is of great significance.

2.2 Technical value of pipeline comprehensive balance

In construction engineering, electromechanical engineering is a very critical part. In mechanical and electrical engineering, it is often necessary to install a large number of pipes in the public passages and computer rooms of buildings. In the traditional construction process, mechanical and electrical engineering majors work independently and design and install pipelines according to their own construction requirements and standards. Insufficient overall consideration of mechanical and electrical engineering leads to confusion in pipeline layout and design, and some even fail to meet the construction requirements of mechanical and electrical engineering, making subsequent projects impossible. The application of comprehensive balance technology of pipeline layout in electromechanical engineering has completely changed this problem. This technology is a new one.

It is called "one of 10 emerging technologies" by the construction engineering community. The comprehensive balance technology of pipeline layout can fully consider the balance and coordination among the specialties in the building, make the construction site more orderly, and help the construction unit to organize and manage the whole construction process. As far as building mechanical and electrical engineering is concerned, due to the numerous pipelines and complex design, the pipeline, hanger and bridge can be designed through the comprehensive balance technology of pipeline layout, which can ensure the full and reasonable design of pipelines in various disciplines of mechanical and electrical engineering, maximize the use of building space and improve the stability and safety of building mechanical and electrical equipment lines. On the premise of ensuring the function of mechanical and electrical equipment, solve the contradiction between mechanical and electrical equipment installation units and promote the smooth completion of mechanical and electrical installation engineering construction.

2.3 technical points

First, the joint design and construction detail design can be improved quickly by using the comprehensive balance technology of pipeline layout. The construction site map of construction machinery and electric power is designed in detail to ensure more orderly management of the construction site. Secondly, on the premise of ensuring the basic functions of building mechanical and electrical equipment, it can solve the elevation position problem of various pipeline equipment, design different positions for different pipelines, prevent cross-installation conflicts during installation, and meet the requirements of building structure and decoration.

Thirdly, when arranging the pipelines of mechanical and electrical equipment, we should fully consider various factors, such as the construction sequence requirements of different pipelines and the maintenance requirements of different pipelines during use, so as to ensure that different pipeline constructions do not affect each other. Fourthly, the comprehensive balance technology of cost control and pipeline layout can comprehensively design the hanger in the process of electromechanical installation, so that the hanger can meet more electromechanical professional construction as much as possible, reduce the workload of hanger disassembly and transformation, improve economic benefits, avoid affecting the construction period and reduce costs.

Application of comprehensive balance technology of pipeline layout in building electromechanical engineering

3. 1 Pipeline Layout

Determine the drawing format. Drawing format is a unified standard and specification used in drawing various pipelines. When drawing format standards, we should try our best to unify the marking methods of various disciplines, and try our best to combine the drawing format of the original design drawings to avoid too many marking methods with different formats on the comprehensive drawing of pipeline layout, so as to determine a unified format, which is helpful to the comprehensive layout of electromechanical engineering pipelines. In the comprehensive balance technology of pipeline layout, the drawing sheet, printing scale and title bar should also be determined, and the selection of drawing sheet and printing scale should be appropriate. On the one hand, it should be easy to read, especially when marking some pipeline data, the font can be smaller and the drawing sheet size should meet the reading requirements.

On the other hand, it should be easy to print. If the drawing scale is too large, the printed drawing area is too large, which is not convenient for carrying and on-site guidance. Therefore, it is necessary to comprehensively consider the drawing size and printing scale. For the contents of drawings, it is necessary to make sure that the scheme gives people an accurate and standardized feeling and avoids misleading other professional operations due to cross-modification of drawings. In order to be suitable for each specialty in the installation of mechanical and electrical engineering, professional drawings can be made separately according to the needs of each specialty and combined with the comprehensive wiring diagram. Each specialty can modify the professional drawings according to the actual situation, and then the design department will modify them uniformly to draw a complete pipeline layout.

3.2 Basic Framework of Pipeline Layout

After the drawing design is completed, it can be used for pipeline design. Before the operation on the construction site, each type of work in the construction process should know the construction drawing, as well as the mechanical and electrical specialty, civil engineering specialty and decoration specialty. We should know our own tasks in the construction process, strengthen communication and coordination among various professions, have overall awareness and comprehensive awareness, arrange and design pipelines, and determine the positions of various pipelines in the building. At the same time, we should consider that different pipelines may cross, so we should avoid the cross phenomenon and set up an evasion framework. For some pipelines that must be modified due to lack of space, clear remarks should be made in the construction drawing, so that the construction drawing and the comprehensive drawing of the pipeline correspond to each other, and the pipeline construction drawing can also reflect the places that need to be modified in time, which is convenient for construction and inspection.

The application of pipeline layout comprehensive balance technology in building electromechanical pipeline layout mainly includes the following aspects. (1) plane positioning. When positioning the pipeline, both the plane and the vertical should be considered. In graphic design, the shape, size and thickness of insulation layer of pipes should be considered, so that the spacing and position of pipes can meet the construction requirements. Positioning is to determine the position relationship between the pipeline and various basic equipment, such as downlights, nozzles, fire horns, tuyeres, etc. , and from a comprehensive point of view to determine the location of all kinds of equipment, to prevent the impact on the appearance, and then pipeline design, pipeline to avoid the location of these equipment, otherwise it does not meet the elevation requirements of the pipeline.

(2) Facade layout. Facade layout is a project from a vertical angle. First of all, we should arrange the pipes that are not allowed to turn over, such as some large-scale pipes and drainage pipes. If the elevation of some areas is relatively tight, only pipelines with large space occupation will be arranged, and pipelines with small space occupation can not be designed for the time being. Other pipelines can be adjusted after installing large pipelines to complete comprehensive coverage. When determining the elevation position, if there is already a drainage pipe, the height difference between the highest point and the lowest point should be calculated according to the actual situation of the drainage pipe, and then the pipe should be attached to the bottom of the beam, and then other pipes should be arranged.

(3) Cross bending design. The comprehensive balance technology of pipeline layout can effectively reduce the cross-construction caused by blind design of pipelines, which easily leads to chaos in the construction site. Therefore, the crossing construction between pipelines should be controlled during pipeline layout, and some positions must be crossed and bent during pipeline installation. For these positions, certain principles should be followed when crossing construction, such as "small pipes make large pipes", "pressure flow pipes make gravity flow pipes" and "cold water pipes make hot water pipes". If the pipeline is installed through, pay attention to the gaps between pipelines, reserve space and position for the crossed pipeline, and lay a foundation for the future maintenance process. For example, the height of the top cover is reserved above the bridge and trunking to ensure the smooth maintenance of the bridge trunking; Try not to turn off the small pipe. Although the comprehensive balance technology of pipeline layout can adjust the design drawings of pipelines, so as to make the pipeline layout more reasonable, comprehensive design should be carried out according to the design situation, functional requirements and technical requirements, and the construction conditions of various professions should be comprehensively considered in the design process.

3.3 Difficulties in pipeline layout

One of the most obvious difficulties in the application of comprehensive balance technology for pipeline layout is how to meet the clearance requirements. Due to the limitation of building structure, it is necessary to make many adjustments when arranging pipelines. According to the position and trend of pipelines, the elevation position of pipelines in various disciplines can meet the construction requirements. For example, in a project, the distance between the corridor beam and the control elevation is 400 mm When laying pipelines, the pipelines that occupy more space should first meet the clearance requirements, that is, the wind pipelines. According to the actual situation, the height of the air duct should not exceed 300mm, and other pipelines cannot be arranged at the lower part of the air duct. Due to the influence of building structure, the height of air duct needs to be compressed in some parts to meet the specific elevation requirements.

In the specific process, we should pay attention to two points. First, because some technical parameters and pipeline specifications on the drawings can be adjusted, it is necessary to go through scientific design before the final design, and all disciplines should communicate with each other to demonstrate the actual situation of the project. For example, due to the actual situation of the building structure, it is necessary to reduce the height of the air duct and the specifications of the drainage pipe. This practice is a concrete measure formulated according to the actual situation. Although this method is not adopted as far as possible in theory, on the premise of satisfying safety and function,

Second, if the adjustment still does not meet the elevation requirements, appropriate measures can be taken to change the building structure or even lower the elevation requirements. We can't blindly violate the law of engineering construction in order to meet the elevation requirements. For example, in the design of this project, we can adjust the position of the bathroom and lower the elevation of the elevator front room. Generally speaking, there is no absolute method in the pipeline design process. Only when the relative design must be flexible according to the actual situation can the pipe network of electromechanical engineering be more standardized and balanced.

4 conclusion

To sum up, there are a large number of pipelines in the construction process of building electromechanical engineering, and the pipe network is complex. The comprehensive balance technology of pipeline layout is of great significance, which can comprehensively arrange various pipelines in electromechanical engineering, improve the rationality and balance of pipeline network and reduce cross-operation. In the specific construction process, according to the actual situation, the comprehensive balance technology of pipeline layout is used to draw drawings, analyze and solve the possible problems in the pipeline installation process, improve the rationality of pipeline layout and reduce various problems caused by pipeline cross construction.
