There are more and more high-rise buildings in modern cities, when installing expansion joint on high-rise buildings, attention should be paid to the technical problems as follows:
1. The number of people using high-rise building water supply and drainage system becomes more and more, water peak instantaneous water and drainage flow is big, once the water supply and drainage pipeline jam accidents, influence scope is bigger. So must have a safe and reliable water supply facilities, suitable water supply and drainage materials and excellent construction quality, properly handle good drainage ventilation problems, ensure the safety of water supply and drainage unobstructed.
2. The number of layer of high-rise buildings is more and height is big, the hydrostatic pressure water supply system and hot water system, in order to guarantee the pipes and fittings are not destroyed, when the design must be carried out on the water supply system and hot water system set up reasonable vertical partition and decompression equipment, to ensure the welding quality of pipeline construction and firmly fixed, in order to ensure normal operation of the system.
3. The function of the high-rise buildings is more, structure is complex, and there are many people involved. In the event of fire, it is easy to spread rapidly and difficult to evacuate and save. Must set up the safe and reliable indoor and outdoor fire water system of filling water system, pipe insulation and pipe well, wear casing wall block should use flame retardant materials, and should carry on the strict inspection, to prevent major fire accidents.
4. The demand of preventing noise and shock is higher, but there are many different kinds of indoor pipeline and equipment, pipeline is long, and there are many sources of noise and shock, so there is need to take consideration to the pipe shock and noise reduction measures to ensure that the installation is firm, the slope is reasonable, and take the necessary measures such as adding damping isolation or flexible connection.
5. High-rise buildings because of the water supply and drainage, fire protection, air conditioning, electrical and other pipeline equipment is various, should be comprehensive arrangement, comprehensive cross to deal with all kinds of pipeline, pipe well according to the pipeline to reasonable layout, reasonable arrangement of construction process, utility piping shall be carried out before construction CAD 3 d graphic simulation and field actual surveying and mapping, in order to avoid pipeline fight phenomenon, facilitate subsequent thermal insulation, decoration and maintenance work in the future.
6. High-rise building structure weight, easy to produce subsidence, should reasonable arrangement of wall pipe installation time, prevent building sink down into your pipeline shear rupture or phenomenon of the slope.
