摘要
在铁路隧道工程建设中,采用水平旋喷桩加固土体的应用越来越广泛。但现行铁路工程定额中没有施工水平旋喷桩的统一计量标准和计价依据。故此文结合蒙华铁路煤运通道的某单洞双线隧道水平旋喷桩施工技术方案,通过对施工水平旋喷桩工料机消耗的测定,分析施工水平旋喷桩的综合单价,为编制施工水平旋喷桩计价定额提供依据。
The application of horizontal rotating- jet grout pile is more and more widely used in the construction of railway tunnel engineering. However, there is no unified measurement standard and valuation basis of horizontal rotating - jet grout pile in current railway engineering quota. Combined with the scheme of of a single tunnel double line tunnel of Mengxi - Central China railway, the artificial material machinery consumption of construction of horizontal rotating - jet grout pile is mensurated, and the unit price is analyzed to provide basis for compilation of the valuation quota.
