Abstract: After years of running the Fankou Pumping Station occurred concrete structure cracks and settlement joint leakage. Cracks would reduce the anti seepage capacity, quicken the carbonation of concrete, cause steel reinforcements to be corroded, and decrease material durability and bearing capacity of the building. There were three kinds of methods on treating cracks and leakage as follows: For the cracks of affecting structure stability and concrete surface, the remedial measure and grouting method were adopted respectively. When cracks affected the performance of the structure, the reinforcement method was used for reinforcing the structure function. And when concrete cracks and settling seams were needed to possess anti seepage function, a suitable bonding material was grouted into cracks and settling seams to form an integration of the structure. Fankou Pumping Station has been put into operation and it is working in perfect order. It is validated that the selected meterials and processing technologies are reliable, successful.
