Embodiment Construction

[0036] The present invention is illustrated in detail with the following examples, based on a solid pavement using precast concrete elements. However, the present invention is not limited thereto, but the present invention can also be used when a solid pavement is constructed using cast-in-place concrete, or a combination of cast-in-place concrete and precast concrete members.

[0037] figure 1 A top view of the foundation 1 and the track grid 3 built on the gravel bed 2 is shown. The gravel ballast bed 2 is a substructure constituting a solid road bearing layer. To this end, in the crushed stone bed 2, a number of pillars 4 made of crushed stones and binding substances are added. The pillars 4 are arranged between the sleepers 5 and can be inserted into the gravel ballast bed 2 without continuous adjustment of the driving operation. For example, under pressure and after placing the pillars 4 in the gravel bed 2 with a grouting nozzle, the running operation can be resumed. ...

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...
