Withstanding 260km/h Typhoons! The Robust Construction Solution for the Coal Bunker of Kalakala Power Plant in the Philippines

图片
Project Challenges: Double Impact of Typhoons and Earthquakes The coal storage bunker of Power Plant in the Philippines has been facing tests from extreme natural conditions since the planning stage: Climate Challenge : Located in a super typhoon zone with wind speeds of up to 260 kilometers per hour, it withstands fierce storms and heavy rains every year. Geological Threat : Situated in a high seismic intensity zone with Z=0.4, the structural stability must be absolutely guaranteed. Cost Pressure : The client requires strict control over overseas construction costs while ensuring safety, and also demands controllable construction periods. Ultra-Large Scale : With a total height of 48.675 meters and a foundation height of 3.0 meters, the long-span dome design poses a great challenge to structural strength for industrial projects. Solutions: Comprehensive Upgrades from Design to Materials Targeting these pain points, our overseas engineering team has tailor-made a combined solu...

  Welded ball Hot press moulding method Unloading: according to the design requirements, adopt semi-automatic gas cutting, profiling gas cutting, CNC flame gas cutting and other methods to unload the steel plate and cut out the round plate of suitable size, when unloading, it is necessary to reserve the welding shrinkage margin for fabrication and installation as well as the machining margins for cutting, edge planing, milling and so on. Heating: The blanks are heated uniformly to about 1050 ° C ± 50 ° C in a reflector furnace or resistance furnace after unloading. Pressing and moulding: Use hydraulic presses and matching convex and concave moulds to press and mould the heated slabs to produce hemispherical shapes. The demoulding temperature should not be lower than 650 ° C. After the hemisphere is pressed and moulded, the wall thickness should be reduced by not more than 13% and not more than 2.5mm according to the design and specification. Cutting bevel margin: can be processe...
