#Railway tunnel #Natm #PKg08 #FFP #MT #Swellex rock bolts This unique rock bolt consists of a welded tube folded in upon itself, sealed at one end. It is re-expanded using a high pressure water flow provided by a special pump and adapter. The bolt is expanded inside the borehole drilled into the excavation wall. • Increased safety and productivity • High efficiency in all ground types • Optimised support and rehab needs • Assurance of optimal installation • Resistance to nearby blasting • Reduction of logistics & HSE hazards • Minimizes stress raisers resulting in best performance #Main #benefits • Fast, simple, safe immediate rock support • High performance in hard, fractured and soft rock • Elongation capacity allowing energy absorption • Measurable installation quality by water pressure • Full column support • No harmful bonding agents (resin / ce

Things you find on a site Survey!! I was on a site for another reason but could not help but notice this, compression elbow used which has disintegrated. The drain was in fact blocked and this was the result of me unblocking it! Experience told me there would be other issues on this flue, which I was correct and I have now cost, to replace the flue, along with the actual reason I was on site. This shows the importance of inspecting the full length of the flue installation. HFL Building Solutions #gasengineering #gassafe #flue

When Micro tunnelling is impossible pipe anchoring can be an option? Still looking for a pipe duct option within the wall.

Spherical Bearing Arrangement in Steel Bridge. 1. Always GBL is diagonally placed to GBT. 2. Always FXB is diagonally placed to FRB. 3.GBL can move in Longitudinal Direction that is Along the Traffic direction. 4.GBT can move in Transvers direction that is Perpendicular to Traffic direction 5. Spherical bearing can take vertical load from 800KN to 26700 KN 6. Good Seismic performance. 7. Minimum Maintenance required. #civilengineering #construction #Indianrailway #bridgeconstruction #structuralEngineering #railways

BREAKING ALL THE RULES OF HDD When Ghella Abergeldie Joint Venture of the Central Interceptor project (Auckland NZ) contacted Universal Underground asking for a solution to install an accurately graded pipe under a six lane motorway in peat with logs and stumps, UULs proposal was unorthodox.  The requirement included all the advantages of TBM (tunnel boring machine) method but without the risk of abandoning the machine if it encountered a timber obstruction. Two and half years in the design, a nervous motor-way authority, super soft ground with isolated hard obstructions and the requirement for an accurately graded pipe, suggested UUL should move on to less risky work. However GAJV recognised UULs solutions to address all stakeholders concerns as the best chance of success. Unique problems require unique solutions and with three attempts to thread the needle past timber obstructions and some unusual HDD practices, UUL pulled this one off against the odds.     #Centralinterceptor #GhellaAbergeldie #GAJV #Watercare #UniversalUnderground #TBM #HDD
