For the water supply of high-rise buildings in the 8° and 9° areas, when the linear length of the drainage riser is greater than 50m, anti-seismic measures
should be adopted. When the linear length is greater than 100m, anti-seismic measures should be taken.Electrical piping with an inner diameter of not less than 60 mm and a cable ladder with a gravity of not less than 150 N/m, a cable duct box, and a busway.
The anti-vibration channel should be reliably connected with the structural body. According to the seismic fortification intensity of the project location, the
seismic force is the main load, which consists of anchors, reinforcement booms, seismic connection members and seismic bracing.
All components that make up the seismic mount should be finished components, and the construction of the link fasteners should be easy to install.
The seismic support of the pipeline shall not limit the displacement caused by the thermal expansion and contraction of the pipeline, and its design shall meet the relevant regulations.
The maximum design spacing of the lateral seismic support of rigid pipelines in new construction is 12 meters, the maximum design spacing of longitudinal seismic
upport is 24 meters; the above parameters of flexible pipelines are halved; the above parameters of pipelines for reconstruction and expansion are halved.
The maximum design spacing of the lateral rigid seismic support of the new rigid rigid duct is 9 meters, and the maximum design spacing of the longitudinal seismic
support is 18 meters; the above parameters of the flexible duct are halved; the above parameters of the reconstruction and expansion pipeline are halved.
