Connection channel freezing method construction technology and device

Номер: CN116537797A
Принадлежит:

The invention belongs to the technical field of tunnel engineering, particularly relates to a construction process and device for a contact channel by a freezing method, and provides the following scheme aiming at the problems that in the prior art, mud water loss cannot be prevented in time, mud cannot be supplemented in time, and a drill rod cannot be stabilized: the construction process comprises two drilling boxes which are respectively arranged in two tunnels; the drilling box is composed of a fixing box and a supporting structure, the supporting structure is arranged at the bottom of the fixing box and used for supporting the drilling box, and the stabilizing structure is arranged on one side of the fixing box and used for enabling the fixing box to be stably attached to the inner wall of the tunnel. The fixing box can be kept stable during hole rotating, too large deviation of drilling in the later period is avoided, slurry is supplemented into the freezing hole in time in the freezing ...

Preparation method of extrusion pipe

Номер: CN103878206A
Автор: LU YUBING, CHEN MAOKUN
Принадлежит:

The invention belongs to the technical field of refrigeration and fine chemicals and in particular relates to a preparation method of an extrusion pipe. The method comprises the following steps: washing and drying a pipe blank, soaking in silicon oil, de-oiling and drying; then, filling an insulated molten filler into the preprocessed pipe blank, naturally cooling and solidifying the filler at normal temperature, putting the pipe blank filled with the filler into a prefabricated three-way mould, and extruding to obtain a prefabricated part, wherein the filler adopts sodium chloride as a base material and is added or not added with other auxiliary materials; finally, performing high-temperature annealing on the prefabricated part, recovering the filler, bending and forming to obtain the extrusion pipe. The process is simple, clean and environment-friendly, achieves material recycling and has a wide application prospect.
