高速铁路聚氨酯固化道床施工工艺及费用分析

Construction Technology and Cost Analysis of High Speed Railway's Polyurethane Curing Ballast Bed

现阶段,我国常用的轨道结构主要有有砟轨道和无砟轨道两种,两种传统的轨道结构形式都有各自的优劣性,聚氨酯固化道床技术作为一种新型轨道结构,融合了有砟轨道和无砟轨道的优势,应用越来越多。现行铁路定额中,关于聚氨酯固化道床的概预算定额还没有成熟的体系。通过研究高速铁路聚氨酯固化道床的施工工艺,并与传统轨道结构施工工艺对比,分析聚氨酯固化道床的概预算编制方法。

Currently,there are two types of track structure commonly used in China:the ballast track and the ballastless track.The two forms have their own pros and cons.As a new type of track structure,the technology of polyurethane curing ballast bed combines both advantages of ballast track and ballastless track,which has been widely implemented.In the current railway quota,there is no mature system of the polyurethane curing ballast bed's budgetary estimate ration.This paper aims to analyze the polyurethane curing ballast bed's budgetary estimate ration preparative method,through the way of researching high speed railway polyurethane curing ballast bed's construction technology and comparing with traditional track structure construction technology.
