INTRODUCTION

IN 2013, Borecut were called upon to cut Turbine Block No.2 (Kusile Power Station) Into manageable sections for removal. The reason for this was that cold breaks had formed in the concrete and proved this would be a structural problem in the years to come. Mechanical breaking was not an option as this method would have proved to be time constraining. The method of Cutting the Turbine block into manageable sections and lifting them to another location seemed the more viable route and proved to be successful. There were a total of 38 sections each ranging from a total weight of 112 tons down to 30 tons. Borecut had a large task on their hands as this Turbine Block had plenty reinforcement. Before the cutting took place, the sections were prepared by installing four Dywidag bars per section with a Girder and hydraulic jacks to lower each section to the ground. See pictures below.

REMOVAL OF EACH SECTION

 
The removal of the turbine block no.2 at Kusile Power Station, could easily well be the largest concrete cutting and drilling job in the south hemisphere with a total amount of 1300 cubic meters of concrete being removed. Each section was transported by a flatbed truck and taken to another site and placed in the exact order it was cast. Each block clearly marked and tagged to identify each cold break. Borecut are proud to be apart of this large scale cutting activity and is proud to have assisted in the methodology planning and successful operation of the Turbine Block number 2 demolition. This has once again proved to Borecut that there is no job too big nor too small and can carry out a professional service to all its clients with quick and safe methods..
