Abstract

The invention discloses a slip form construction method of large-fluidity paving concrete for subway rail base. The large-fluidity paving concrete and a slip form paving machine which is adaptive to the performance of the concrete are applied. The method comprises the following steps that, (1) the slip form paving machine for the subway rail base concrete is in position and debugged; (2) the large-fluidity paving concrete is prepared and transported; (3) the concrete is loaded into a material storage bin, and the slip form paving machine is tested to carry out the slip form; (4) the slip formpaving machine is operated, and the linear shape and flatness of the concrete base are detected; and (5) the surface of the base concrete is finished and maintained. According to the slip form construction method for subway base concrete, the method is low in energy consumption, low in noise pollution and capable of continuously constructing, the automation degree of the construction process is improved, the consumption of manpower and material resources is remarkably reduced, and the method has extremely high popularization and application values.

Description

technical field

[0001] The invention relates to the technical field of concrete slip form construction, in particular to a slip form construction method for paving concrete with high fluidity for subway track bases. Background technique

[0002] In order to alleviate traffic pressure, the operating mileage and construction scale of subways in major cities are increasing year by year. The track bed of the subway is the main structure to bear the load of the train. It is mainly divided into an integral track bed and a gravel track bed. The integral track bed is generally used for underground lines and elevated lines. At present, the widely used integral ballast bed is mainly composed of concrete base, fasteners, elastic cushion and steel rails. The concrete base is made of concrete poured on site. Although the construction process is simple, the formwork needs to be supported before the concrete is poured. Dismantling after completion, periodic assembly and disassembly work w...
