Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] A prefabricated floating slab track bed vibration isolation system, please refer to Figure 1 to Figure 5 In order to facilitate transportation, several groups of floating slabs are spliced ​​adjacent to each other to form a long track bed, the long track bed is embedded in the bottom of the tunnel structure 16, and the outer contour of the long track bed is inlaid with the bottom of the tunnel structure 16 Connection, in order to facilitate on-site splicing and installation, the floating slab is set as a precast concrete slab 1 with a well-shaped structure. Short sleepers 3 are arranged at equal intervals in the long direction. In order to further facilitate on-site splicing and installation, connecting arms 4 are extended on both sides of the waist of the precast concrete slab 1, and U-shaped grooves 5 with openings facing outwards a...

Abstract

The invention discloses a prefabricated floating slab ballast bed vibration isolation system which includes a tunnel structure and a plurality of groups of floating slabs. The floating slabs are adjacently spliced to form a strip ballast bed, the strip ballast bed is embedded at the bottom of the tunnel structure, and inner side face parts of the tunnel structure and the strip ballast bed are filled with wear-resistant elastic layers. The floating slabs each are a precast concrete plate which is of a #-shaped structure, the center of the precast concrete plate is provided with a first maintenance groove with a rectangular cross section, short sleepers are equidistantly arranged in the length direction of the precast concrete plate, connecting supporting arms extend on the two sides of thewaist of each short sleeper, the two sides of each connecting supporting arm are provided with U-shaped grooves with outward openings, installing grooves are reserved at the bottom of the U-shaped grooves, groove steel is adaptively mounted in the U-shaped grooves, and through holes are formed between the two-side U-shaped grooves. The prefabricated floating slab ballast bed vibration isolation system not only is convenient to transport, but also makes it easy to perform splicing and maintenance in a tunnel, can ensure running safety and have high vibration isolation capability.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a prefabricated floating slab track bed vibration isolation system. Background technique [0002] Currently, the best vibration isolation capability in urban rail transit is the vibration isolation system of the floating slab track bed cast on site, such as rubber floating slab track bed and steel spring floating slab track bed. In order to ensure the vibration isolation effect, each of their boards is made very large and heavy, and can only be cast on site. However, cast-in-place has the disadvantage of slow construction speed. Considering that many sections do not require such a large amount of vibration isolation, reducing some of the vibration isolation capacity and taking the way of prefabricated floating slabs has become a research hotspot and focus in the field of vibration isolation of urban rail transit in China in recent years. [0003] The problems to be s...
