Construction method of guard rail type ballastless track bed
The invention relates to the technical field of railway ballastless track bed construction, in particular to a guard rail type ballastless track bed construction method. Comprising the steps of construction preparation, survey lofting and foundation mark survey setting, beam surface chiseling cleaning, sleeve connecting steel bar installation, base steel bar binding, bridge expansion joint embedded part installation, base and groove formwork installation, base concrete pouring and maintenance, isolation layer geotechnical cloth and elastic base plate laying, groove insulation steel bar framework installation and ballast bed bottom layer steel bar binding. The method comprises the following steps of: distributing double-block type sleepers, transporting tool rails, assembling double-block type track panels, roughly adjusting track lifting of the double-block type track panels, binding steel bars on the upper layer of a track bed, distributing guard wheel sleepers, assembling guard wheel track panels, roughly adjusting the sizes of the guard wheel track panels, mounting and adjusting track bed templates, finely adjusting the double-block type track panels for the first time, adjusting the sizes of the guard wheel track panels, and finely adjusting the double-block type track panels for the second time. The method comprises the steps of guard rail row size rechecking, ballast bed concrete pouring, stress relief, concrete curing and data acquisition.
