某桥台边坡注浆处治方案分析

Analysis of Grouting Treatment Scheme for a Bridge Abutment Slope

注浆法是用气压、液压或电化学原理,把某些能固化的浆液注入天然的和人为的缝隙或孔隙,以改善介质的物理力学性质。该文针对河北某高速公路某桥台处边坡出现的纵向裂缝,对花管注浆参数进行了设计,给出了详细的注浆工艺方法、参数与施工工艺。可为类似的边坡处治提供一定的参考。

Grouting method is to inject some solidified grout into natural and man-made crevices or voids with the principles of air pressure,hydraulic pressure or electrochemistry,so as to improve the physical and mechanical properties of the medium [1].Aiming at the longitudinal cracks in a bridge abutment slope of a highway in Hebei Province,this paper designs the parameters of flower tube grouting,and gives the detailed grouting technology,parameters and construction technology.It can provide some reference for similar slope treatment.
