Organizing and Managing the Implementation of Large Diameter Tapping and Plugging Technology for a Major Sanitary Improvement Project in Ho Chi Minh City, Vietnam

摘要

This paper will discuss the organization, management and implementation of tapping and plugging technology on large diameter reinforced concrete cylinder pipe. The configuration of a 78 inch, 60 inch and 48 inch Triple STOPPLE? on concrete cylinder pipe was one of the largest operations of this type performed at that time in the Asia Pacific Region. The procedure facilitated the installation of a new under water crossing of an important water supply line as part of a major Peoples Committee of Ho Chi Minh City, Vietnam environmental sanitation and public improvement program. The program consisted of installation of storm and sewage collector systems as well as dredging of canals to alleviate flooding and to promote natural tidal flushing of estuaries for this major Asian city experiencing rapid growth. The demands related to the particular location, the client's unfamiliarity with the technology and types of pipes presented challenges in planning, organizing, designing and managing field operations.
