Advance of study on irrigation techniques in greenhouse;

According to the analysis of the content of HA, microorganism activity and exchange capacity of the raw material to produce the HA microorganism liquid fertilizer (the vegetable specific-fertilizer in the greenhouse), the best raw material produced for the liquid fertilizer was made certain.

Occurrence characteristics and biocontrol feasibility of plant diseases in greenhouse were analyzed and some actual applications exemplified.

The application of pre-casting technology through advanced installed pipe shed in portal section construction of highway tunnel in fault-rupture zone;

The mine tunneling construction numerical simulation supported by pipe shed in subway tunnel

Construction skill of karst tunnel and application of pipe shed

Optimum diameter analysis of pipe roofs applied in underground engineering with shallow overburden;

Analysis of mechanical property of concrete-filled steel tubular pipe roof underpass bridge;

Tunnel construction technology of long pipe roof beneath airport taxiway;

Three-Dimensional Finite-difference Method Analysis Appliance to The Pipe-shed Entrance of Large Span Tunnel;

Advanced large-pipe-shed construction technology of Guanyintang tunnel under crossing Lian-Huo expressway

In this paper, the way how to install the pipe-shed for whole length to the tunnel, how to link up all working procedures and how to form a loop to prevent the deformation of surrounding rock are introduced.
