Method for constructing a rigid track and a communication track

Abstract

The invention relates to a method for constructing a rigid track for high-speed rail traffic. According to said method, the inventive rigid track is either constructed from precast concrete components (7) arranged on a track bed structure (2,4;16), an intermediate region between the concrete components (7) and the track bed structure (2,4;16) being filled in with a solidifying filling material (8) in order to fix the position of the concrete components (7), or from cast-in-situ concrete or a combination of concrete components (7) and cast-in-situ concrete on the track bed structure (2,4;16). The inventive method is characterised in that the track bed structure (2,4;16) is created from an existing ballast bed (2), the ballast being at least partially compacted. The invention also relates to a corresponding communication track of a rigid track.

Description

technical field

[0001] The invention relates to a method for constructing a solid road surface for high-speed rail transit by using prefabricated concrete components. The prefabricated concrete components are laid on a load-bearing layer. The intermediate space is poured with a gradually solidified filling material, or constructed on the load-bearing layer (2, 4; 16) with some combination of cast-in-place concrete or prefabricated concrete elements (7) and cast-in-place concrete. In addition, this The invention also relates to a corresponding solid roadway. Background technique

[0002] The construction of high-speed rail traffic roadways is usually either built on a crushed stone ballast superstructure, or has a solid road surface, for example, composed of a large number of prefabricated concrete elements. The disadvantage of the crushed stone ballast superstructure is the high maintenance intensity required, while the solid road surface has to pay a longer construction ti...
