公路桥涵台背施工液压夯机补强技术研究

Study on the Strengthening Techniques of Hydraulic Ramming Machine Utilized in Highway Bridge and Culvert Abutment Back Construction

随着人们对公路行车舒适要求的日益提高,减少台背跳车,公路桥涵台背施工受到越来越高的重视。公路桥涵台背施工液压夯机补强技术,在青海公路桥涵台背施工中已进行应用,且取得良好效果。本文以在建的大力加山至循化高速公路为例,通过对液压夯机补强桥涵台背施工技术做研究,希望在公路桥涵台背施工中得以推广。

With the increasing requirements of driving comfort, highway bridge and culvert abutment back construction is getting more and more attention. To reduce the vehicle jumping at the back of abutment, the strengthening techniques of hydraulic ramming machine has already been applied in highway bridge and culvert a- butment back construction, and the effect is satisfactory. In this paper, combining with the construction of Da li- jiashan-Xunhua highway, through the research on techniques of hydraulic ramming machine, hoping that the strengthening techniques can be spread in highway bridge and culvert abutment back construction.
