Key Technology Research into Foam Concrete Lightweight Embankment with Prefabricated Baffle Instead of Conical Slope at Bridge-Head

Abstract

In order to solve the problems of bridgehead diseases and reduced space under bridge due to conical slope at bridge-head, in this paper, a construction method was explored to utilize inside step-slope on embankment, prefabricated baffle structure on the outside of embankment and foam concrete, with self-supporting after solidification, low elastic resistance, adjustable strength and durability, to prevent vehicle bumping and, without conical slope, to enlarge the space under bridge. It has excellent technical and economic benefits.
