Research on Key Technologies for Design and Construction of Prefabricated Pile Plate Roadbed
In order to solve the problem of severe soil shortage and large-scale occupation of farmland in the construction of expressways in plain and micro hilly areas,the G0321 Dezhou-Shangrao Expressway Joint Section actively implements the concept of green highway construction,and for the first time in Anhui,a frame system pile plate subgrade composed of prestressed concrete pipe piles and precast reinforced concrete slabs has been widely applied in the construction of new expressways.Based on engineering cases and construction practices,this paper comprehensively introduces the design and key construction technologies of the new type of roadbed structure,and proposes guiding construction quality evaluation standards,providing a phased summary and technical reference for the further development of prefabricated pile slab roadbed.
