  • ESDU TM 175 - Self-loosening of bolted joints
    Reduce the portion of the external load carried by the bolt by, for example, using stiffer members or non-fixed spacers with care taken to avoid extra potential slip surfaces in the joint (Derivation 24). .... Use long , thin bolts with an l / d ratio greater than 5 (Derivation 30).
  • Characteristics of Water Ingress in Norwegian Subsea Tunnels
    As extra precaution, the great water depth and limited rock cover taken into con- sideration, grouting was however carried out in order to seal the joints and also possibly improve the quality of the zone material. .... Excavation was started with reduced round length (3 m), shotcreting, systematic radial bolting and installation of 6 m long spiling bolts.
  • Cases of instability caused by weakness zones in Norwegian tunnels
    As an extra precaution, the depth of water and limited rock cover was taken into consideration and grouting was carried out to seal the joints and assist in stabilising the zone. .... Excavation was started with a reduced round length (3 m), shotcreting, systematic radial bolting and installation of 6 m long spilling bolts (Karlsson 2008).
  • Monitoring the performance of rock reinforcement
    The area was supported with grouted friction bolts and 6 m long , single strand, bulbed cable bolts installed at 2 m spacing down the centre of the final proposed span as shown in Figure 3. .... Four of these cable bolts were instrumented to record the extra load carried by them after the stripping firings.
  • Geometric design, roadside safety features, roadside hardware monitoring, and scenic loop tours
    For additional strength during the collision with the impact atten- uator, wheel struts brace the connection between the axles and the frame and an extra steel plate is bolted to the existing impact plate. .... In addition, wire rope cables connect the ends of the two longer beams to the bogie frame. .... These modifications turned the test bogie into a ide impact car- riage .

    Support of a long metal piece so that the human can concentrate on bolting ) is considered to Vision (P5-200MMX). .... By acting as a third hand, the support would enable human to carry out the work more freely enabling the use of extra resource for creating new changes to the object or increase of efficiency.
