Abstract

Abstract:

The matching modes of construction machinery of diaphragm walls inserted into rocks are versatile and complex,and the construction organization is difficult.The characteristics of the construction of diaphragm walls inserted into rocks by different machines are studied and summarized,with the construction of diaphragm walls of Qiushui Square Station of Nanchang Metro as an example. The construction technologies are optimized and rational technologies are used.As a result,the construction efficiency is improved.

Key words: Nanchang Metro, diaphragm wall inserted into rocks, grab bucket, trenching machine, drilling machine
