RECOMMENDATIONS FOR THE DESIGN AND CONSTRUCTION OF PRESTRESSED CONCRETE

The recommendations cover the planning, installation, testing and monitoring of permanent and temporary ground anchors bonded to the ground by cement grout. The recommendations are published under fip/2/7, 15.918, ISBN 090862 195. A temporary anchor is designed to last for a period of less than two years. Recommendations are given on geotechnical information required for ground conditions in both soils and rocks. The separate responsibilities of the contractor and the consultant are clearly defined. Examples are given of the various types of anchorages and safety factors involved. The main types of cement grout injection anchors are illustrated. Acceptable types of steel for use in the tendon bond length are specified. Methods of drilling holes, water testing, manufacture, handling and insertion of anchors, grouting, corrosion protection, testing and stressing procedures, records of work and subsequent monitoring are all dealt with. It is important that grout does not reach the structure being anchored during grouting otherwise a prestressed grout column is produced. To prevent electrical effects, only one type of metal should be used. Corrosion protection systems should be checked before use and any anchor should have been proved by tests or experience before use. (TRRL)
