Research on Key and Difficult Construction Technologies of Expressway Based on Standardized Construction
The construction period of expressway is generally long,especially when involving unconventional structures.In order to meet the requirements of construction accuracy,the cost and construction period will increase accordingly.In order to better meet the requirements of construction period and project cost on the construction site,it has been decided to adopt the concept of standardized design and refined construction to unify the management of the construction site.This article takes the construction of a highway in Guangdong Province as an example.After adopting the standardized design,the key and difficult problems,including special roadbeds and high piers of bridges,are unified.The results confirmed that after the standardized construction,the construction quality assurance rate,construction period,and cost were correspondingly saved.
