Test on Grouting Reinforcing Technique of Bridge Abutment Bump in Express Way

Abstract:

For the bridge abutment bump of express way in operation, through physical simulation experiment on the bridge-head settlement were studied to obtain the general rules of bridge-head settlement as well as the effects and parameters while grouting below the bridge-head tie-board. Grouting reinforcing method was applied to the Ning-Su-Xu West Wei River Highway Bridge; deal with the problem of bridge abutment bump. Through slurry material strength test, drill core sampling method and ground penetrating radar detect effects of grouting. Experimental results show that: By the grouting treatment below the bridge-head tie-board, which take the empty area to be filled with slurry material and make it dense, forming a whole curtain, and the density and integrity of the padding were enhanced, so, strengthening effect is very good. The practice of grouting reinforcing proves that the technique is low-cost, short construction period, and good results. So it is especially true of treating for the abutment bump of express way in operation.
