HUMBER BRIDGE SLIPS INTO SHAPE

The author gives an account of the construction of the new Humber Bridge, where delays and inflation are adding greatly to the cost, with particular reference to steps that are being taken to speed up construction. The rate of slip forming has been increased on the legs of the Barton Tower to as much as 180 mm an hour. Reinforcement has been added to the lower section of each tower leg so that cable spinning and catwalk erection can be commenced before the two remaining portal beams are cast. Details are given of the Barton Tower which is similar to the Hessle Tower that has already been constructed on the north bank. The 150M high legs are hollow columns which taper from 6M by 6M to 4.5M by 4.75M at the top. On completion one leg will house A ladder and the other a lift for maintenance purposes. Details are also given of the working platform, jacks and tower cranes being used during construction. The 48 jacks are of 6+ capacity and climb on a 35 mm steel tube set in the concrete, which is extended as construction takes place. A hydraulic pump actuates a timer that controls the rate of climb of the jacks and at the same time feeds the rams, which raise the deck structure and sliding formwork. This bridge will be the longest suspension bridge in the world. /TRRL/
