AUA Guidelines for Backfilling and Contact Grouting of Tunnels and Shafts

The underground construction industry will find these guidelines useful for minimizing misunderstandings related to backfilling and contact grouting terms and methods; improving the quality of contract documents related to backfilling and contact grouting and the in-place material; reducing costs and schedule time; and avoiding or minimizing potential claims. The book focuses on how cementitious grouting is used in conjunction with the excavation and lining of tunnels, shafts, and underground caverns in rock. In order to understand and protect the historic environment wherever possible, archaeologists are faced with the crucial task of making decisions on how best to combine the needs of development whilst maintaining our archaeological heritage. Written for theindividual who does not have an extensive background in tunnelingbut who has to make tunneling decisions, the various tunnelingmethods are discussed to help in the determination of theappropriate method. The committee includes a wide range of experts representing engineering firms, contactors, equipment and material suppliers, and consultants.

Underground Cable Thermal Backfill

AUA Guidelines for Backfilling and Contact Grouting of Tunnels and Shafts

Abstract: Provides guidelines for filling of voids for soft ground and rock tunnels and shafts. The greatest use of pressure grouting is to improve geomaterials soil and rock. As a key component of modern grouting programs, ultrafine cement is an ideal solution for geotechnical engineers and construction contractors who are grappling with the challenges of managing costs while developing sites that may be less than ideal. The underground construction industry will find these guidelines useful for minimizing misunderstandings related to backfilling and contact grouting terms and methods; improving the quality of contract documents related to backfilling and contact grouting and the in-place material; reducing costs and schedule time; and avoiding or minimizing potential claims.
