Embodiment Construction
[0038] Below in conjunction with embodiment the present invention will be further described.
[0039] A flexible protective structure for waterproofing and vibration reduction of a ballastless track structure, between the bottom of the base plate of the ballastless track and the surface layer of the foundation bed / the top surface of the bridge deck, a waterproof joint layer and a buffer protection layer are laid in full width (full section laying), Among them, the waterproof connection layer is located under the buffer protection layer; if the bottom layer is the surface layer of the subgrade bed, the penetration depth of the waterproof connection layer into the graded gravel on the subgrade bed surface is required to be no less than 5mm; the bonding between the waterproof connection layer and the buffer protection layer The strength is not less than 0.2MPa, and the interlaminar shear strength between the waterproof joint layer and the buffer protection layer is not less than 0...
