The LiaoDu International Hotel constructs to design for catchment

Summary

This design drains and supply engineering for the Liao Du International Hotel, that building highly is 54.8 meters, total 13 F, mainly from living water supply engineering, fire fighting water supply engineering, the indoor drain and hot water engineering the four-part cent of engineering. The main design of living water supply system includes:Make sure cent area and water supply method, choose water supply piping to take care of path, and underground store chosen etc. of pond and life water pump;The main design of fire fight water supply system includes:The penstock water supply cent area, the choice fire fight water supply piping tube material and tube path, design a penstock box, wet type to automatically report to the police valve, from spray the head, decompression valve and decompression bore plank and choose a penstock to pump and spray a pump...etc.;The indoor drains the main design of system to have:The indoor catchment adopts dirty waste water confluence system and ventilates way adoption appropriation to ventilate a tube form, the choice drain pipe takes care of material and its tube path, first floor adoption alone emissions and gather the design of water well and sewage pump etc.;The main design of hot water system includes:The hot water system divides area in accordance with the cold water system, choose a hot water tube to take care of material and its tube path, design the hot water machine set, hot water box, inflation tube and hot water circle pump.
