Heavy-du­ty sup­port­ing sys­tem SL-1

The heavy-du­ty 'con­struc­tion kit' for tun­nel-build­ing

The mo­d­u­lar­ly de­signed Doka heavy-du­ty sup­port­ing sys­tem SL-1 pro­vides com­plete formwork so­lu­tions for wide­ly dif­fer­ing tun­nel cross-sec­tions, re­gard­less of shape and load.


High­ly cost-ef­fi­cient

as it is su­per­b­ly adapt­able 

  • min­imis­es in­vest­ment costs be­cause many of the sys­tem components are rentable
  • the sys­tem beams, wal­ings and struts can be ar­ranged in vari­able con­fig­u­ra­tions, en­abling op­ti­mum use to be made of each item of equip­ment
  • flex­i­ble in terms of con­struc­tion work­flow, as it is com­pat­i­ble with Large-area formwork Top 50
  • is ex­act­ly planned by Doka Formwork Ex­perts to en­sure stream­lined forming

Fast con­struc­tion progress

achieved by op­ti­mised over­all con­cept 

  • short set-up times, thanks to pre-as­sem­bled formwork and HD sup­port­ing-unit components
  • few­er form-tie points, as Mul­ti-pur­pose wal­ings SL-1 WU 16 and Form-ties 20 are used
  • short re­po­si­tion­ing times, achieved by the all-hy­draulic formwork so­lu­tions
  • easi­er work­ing con­di­tions, thanks to the wide spac­ing be­tween the par­al­lel gird­er­frame units, and the heavy-du­ty te­le­s­cop­ic screw-jack sys­tem

Ex­cep­tio­n­al­ly high work­place safe­ty

thanks to the built-in safe­ty sys­tems 

  • safe work lo­ca­tions as­sured by in­te­grat­ed work­ing plat­forms and lad­der­ways
  • de­tailed as­sem­b­ly and util­i­sa­tion plan­n­ing makes for ex­e­cu­tio­n­al re­li­a­bil­i­ty
  • safe trav­elling even on steep lon­gi­tu­d­i­nal and trans­verse gra­di­ents
  • re­li­a­bil­i­ty as­sured by tried-and-test­ed, pre-di­men­sioned sys­tem de­sign
  • safe plac­ing of re­in­force­ment steel, from the Work­ing scaf­fold Mo­d­ul
