The construction monitoring control of hammer penetration type prestressed high strength concrete (PHC) pipe piles in expansion areas

Abstract

Abstract:

Abstract:Combining with engineering example,this paper introduced the construction measures,the construction monitoring methods and results of prestressed high strength concrete (PHC) pipe piles in expansion areas.After some monitoring methods,such as excess pore water pressure, deep soils displacement and pile head displacement etc.were adopted in the construction process to control the construction sequence and schedule,the response of earth squeezing from group pile and the impact on external area were controlled effectively,and the construction quality was guaranteed.

Key words: ">Keywords:">expansion areas, prestressed high ">strength concrete, pipe pile, construction monitoring, response of earth squeezing from group pile
