Embodiment 1

[0046] Such as Figure 1 to Figure 9 As shown, the road vibration isolation system of Embodiment 1 of the present invention includes a vibration-isolated roadway 100 and a front roadway 200 located around it, a rear roadway 300, a left non-traffic road 400 and a right non-vehicle roadway. The roadway 500, wherein the vibration-isolated roadway 100 is located above the underground space; the vibration-isolated roadway 100 includes a concrete cushion 110, steel spring floating slabs 120, asphalt pavement 130, curb stones 140 and roadside stones 150.

[0047] Above-mentioned concrete pad 110 is made up of paving layer 111, slope surface layer 112 and boss 113, and paving layer 111 is laid on the roof slab 600 of the building in underground space, and slope surface layer 112 and boss 113 are all arranged on paving. The upper surface of the layer 111 and between them form a longitudinal drainage ditch 110 a extending along the driving direction V of the vibration-isolated roadway 1...

Embodiment 2

[0068] The road vibration isolation system of the second embodiment of the present invention is basically the same as that of the first embodiment, and their difference is that in the second embodiment, the concrete cushion 110 is also provided with a horizontal drain perpendicular to the driving direction V of the vibration-isolated roadway 100 The culvert, slope layer 112 also has an aspect towards the lateral drainage culvert.

Embodiment 3

[0070] The road vibration isolation system of Embodiment 3 of the present invention is basically the same as Embodiment 1 or Embodiment 2, and their difference lies in that the slope of the slope layer 112 towards the horizontal drainage ditch is 0.47°.

Abstract

The invention discloses a road vibration isolation system for preventing underground spatial structure vibration and a construction method thereof. A steel spring floating plate is arranged between the roof of a building in an underground space and an asphalt pavement as a travelling pavement above the roof, through spring shear stiffness of spring vibration isolators and compression stiffness of flexible water stopping materials at left and right sides of the floating plate, floating plate vertical support and lateral support stiffness is formed, through a shear hinge and the flexible water stopping materials at front and rear ends of the floating plate, floating plate vertical deformation and smooth longitudinal stability without mutation are realized, and the flexible water stopping materials, kerb drainage ditches and longitudinal drainage ditches are arranged so that accumulation of rainwater in gaps between the floating plate and a slope surface layer is avoided and rainwater-caused corrosion damage to the spring vibration isolators is prevented. The road vibration isolation system can prevent road traffic-caused underground spatial structure vibration, has good vibration isolation effects, can reliably work in an outdoor environment for a long time and is convenient for construction.

Description

technical field [0001] The invention relates to a road vibration isolation system suitable for preventing vibration of underground space structures and a construction method thereof, which can prevent vibration of underground space structures caused by road traffic. Background technique [0002] Urban underground space is an effective way to alleviate the bottleneck of urban land use, so a lot of underground space needs to be planned under the road. However, during the operation of the vehicle, the vibration generated by the uneven road surface including the installed speed brake is transmitted to the building through the road structure, causing the wall and floor of the building to vibrate, and generating secondary structural noise in the building room. Therefore, the road traffic simultaneously The vibration problem of the underground space structure is brought about. The long-term and persistent micro-vibration has a serious impact on people's work and life, and also has ...
