Some advanced construction technology of concrete face rockfill dam of Tianshengqiao Ⅰ Hydropower Station is introduced in this paper such as manufacture and installation of copper sheer water stop,embedding and installation of vertical level displacement meter with length of 400 m,placement plinth using slip form with track as well as Ⅱ A material scaling using reverse scraper directed by laser.

Through presentation of the structure design of concrete slab of Nanshan reservoir CFRD,design of flexible slipform,mix design of slab concrete,quality control in construction process and experience in slab concrete placement by flexible slipform,the paper provides rational and workable technology,and construction control way for slab concrete construction of similar CFRD.

An introduction of a son of new style slide rails design for continuous rolling mill reheating furnace.

The ablation and erosion of high temperature(2 000~3 000 ℃)and ultrahigh speed (>5Ma)twophase exhaust on the slide track surface of a missile launcher, together with the corrosive action of the ablation residue on the slide track surface in humid and salt mist environment, account for the breakdown and decreased service life of the launcher.
