A combination of permanent and temporary water and electricity works in engineering construction is to install permanent fire risers and bury permanent lighting pipelines through penetration of permanent fire risers and permanent lighting pipes,wires and fixtures in advance in the stage of construction of main works,in order to achieve the purposes of using permanent fire risers for temporary fire water and construction water supply and permanent lighting systems for lighting in construction.This not only greatly improves the site image of safe and civilized construction,but also meets the requirements for green construction,energy saving and environmental protection.Therefore,a combination of permanent and temporary water and electricity works has promising prospects of development,promotion and application.
