[0033] Reference Figure 1-4 The figure shows a preferred embodiment of the present invention.

[0034] The construction method of the vibration reduction structure adjacent to the traffic track includes the following construction steps:

[0035] 1) The perimeter of the foundation pit is constructed to form a plurality of adjacent interlocking support piles, which are arranged around the perimeter of the foundation pit to form a surrounding support structure 202. After the underground structure 201 of the building main body 200 is constructed in the foundation pit, an empty fertilizer trough is formed between the support structure 202 and the underground structure 201. The fertilizer trough is arranged around the perimeter of the underground structure 201 and is cleaned.

[0036] The support structure 202 can support the foundation pit and is constructed before the foundation pit is excavated, and forms a surrounding support for the periphery of the foundation pit;

[0037] 2) Two longitudinally arranged buffer layers 301 are placed in the fertilizer tank, one buffer layer 301 presses inward against the outer periphery of the underground structure 201, and the other buffer layer 301 presses outward against the supporting structure 202; the two buffer layers 301 are spaced apart, and a central gap is formed between the two buffer layers 301;

[0038] The buffer layer 301 is provided with a plurality of transversely arranged transverse elastic structures. The transverse elastic structure on one buffer layer 301 abuts against the outer periphery of the underground structure 201 , and the transverse elastic structure on another buffer layer 301 abuts against the supporting structure 202 .

[0039] 3) Insert an isolation layer into the middle space, wherein the isolation layer is provided with an internal elastic structure; multiple isolation layers are arranged at intervals to divide the middle space into multiple isolation cavities;

[0040] 4) Filling multiple isolation cavities with solidified soil to form multiple backfill layers 303. The isolation layers are squeezed by adjacent backfill layers 303, the internal elastic structure is in a compressed state, and the lateral elastic structure is squeezed in a lateral compressed state; multiple backfill layers 303, multiple isolation layers and two buffer layers 301 are combined into one to form the vibration reduction structure 300.

[0041] The above-mentioned construction method for a vibration-damping structure adjacent to a traffic track comprises forming two buffer layers 301 in a fertilizer trough. The buffer layers 301 have a transverse elastic structure that can elastically buffer vibrations generated by the traffic track. Multiple isolation layers are arranged in the middle interval between the two buffer layers 301 to form multiple isolation cavities. The isolation cavities are then filled with a backfill layer 303. The isolation layers have an internal elastic structure that can elastically isolate vibrations generated by the traffic track. The vibration-damping structure 300 provides multi-directional buffering and isolation for the vibrations generated by the traffic track, significantly reducing the impact of the vibrations generated by the traffic track on the building structure 200.

[0042] In addition, the vibration reduction structure 300 is formed in the fertilizer trough. After the underground structure 201 is completed, construction can be carried out directly in the fertilizer trough, avoiding subsequent re-excavation and construction, greatly improving construction efficiency, reducing construction costs, and simplifying the construction structure.

[0043] In this embodiment, in construction step 1), after the fertilizer trough is cleaned, the bottom of the fertilizer trough is compacted and the side walls of the fertilizer trough are leveled to facilitate the subsequent construction of the vibration reduction structure 300 in the fertilizer trough.

[0044] In this embodiment, in construction step 2), a plurality of transverse holes arranged transversely therethrough are provided in the buffer layer 301, and the transverse elastic structure includes an elastic column 3015 passing through the transverse hole, with both ends of the elastic column 3015 extending to the outside of the transverse hole respectively; in construction step 4), after the isolation cavity is filled to form the backfill layer 303, the elastic column 3015 is squeezed and compressed and accommodated in the transverse hole.

[0045] In this way, by forming multiple elastic columns 3015 in the buffer layer 301, and in the vibration reduction structure 300, the elastic columns 3015 are in a compressed and deformed state, elastic supports are formed at multiple positions inside the vibration reduction structure 300, and can play a role in elastic buffering of vibrations.

[0046] The buffer layer 301 may be formed by constructing a plurality of concrete blocks, and transverse holes may be formed in the concrete blocks, thus facilitating the construction of the buffer layer 301 .

[0047] In this embodiment, in construction step 2), the middle fixed sleeve of the elastic column 3015 is provided with a fixing ring 3013, and the fixing ring 3013 is embedded and fixed in the middle of the transverse hole, and the middle of the elastic column 3015 is in a fixed state; in construction step 4), during the process of the elastic column 3015 being squeezed and compressed and deformed, the middle of the elastic column 3015 remains in a fixed state, and the two sides of the elastic column 3015 are compressed and deformed inward until the elastic column 3015 is compressed into the transverse hole.

[0048] By arranging the fixing ring 3013, the connection between the elastic column 3015 and the transverse hole is facilitated, and the middle part of the elastic column 3015 can be kept in a fixed state. When the elastic column 3015 is in the process of elastic compression deformation, the middle part of the elastic column 3015 is kept stationary, thereby facilitating the deformation of the elastic column 3015 and guiding the deformation of the elastic column 3015.

[0049] In this embodiment, in construction step 2), side sections 3011 are formed on both sides of the elastic column 3015, and a middle section 3012 is formed in the middle of the elastic column 3015. A fixing ring 3013 is fixedly mounted on the middle section 3012, and the side sections 3011 are movably arranged with the transverse hole. A plurality of transversely arranged axial holes 3014 are provided in the side sections 3011. The plurality of axial holes 3014 are arranged around the axis of the side sections 3011 at intervals. The inner ends of the axial holes 3014 extend to the middle section 3012, and the outer ends of the axial holes 3014 pass through the ends of the elastic column 3015.

[0050] In construction step 4), during the compression and deformation of the elastic column 3015 , the middle section 3012 is in a fixed state, the side section 3011 is squeezed and compressed and deformed toward the transverse hole, and the multiple axial holes 3014 guide the compression and deformation direction of the side section 3011 .

[0051] By arranging the axial hole 3014 in the side section 3011, when the elastic column 3015 is compressed and deformed, the deformation of the side section 3011 is facilitated, the deformation of the side section 3011 can be guided, and there is enough space for the side section 3011 to be compressed and expanded.

[0052] In this embodiment, in construction step 2), the buffer layer 301 has an inward-facing side surface toward the middle interval, and a longitudinal plate 302 is arranged in the middle interval. The longitudinal plates 302 are respectively fixedly connected to the ends of the plurality of elastic columns 3015, and have elastic gaps between them and the inward-facing side surface;

[0053] In construction step 4), after the backfill layer 303 is filled in the isolation cavity, the backfill layer 303 presses the longitudinal plate 302 to move toward the inner side, and the elastic column 3015 is simultaneously squeezed and compressed and deformed until the elastic column 3015 is compressed into the transverse hole, the longitudinal plate 302 presses against the inner side, and the elastic column 3015 is in a compressed and deformed state.

[0054] By arranging the longitudinal plate 302, the longitudinal plate 302 is connected to the ends of multiple elastic columns 3015. When the longitudinal plate 302 is pressed, the multiple elastic columns 3015 can be synchronously driven to compress and deform, thereby ensuring the consistency of the elastic deformation of the multiple elastic columns 3015 and realizing multi-position synchronous elastic buffering vibration.

[0055] In this embodiment, in construction step 3), the isolation layer includes two isolation plates 305 arranged at intervals, and the internal elastic structure includes an elastic layer 306. The elastic layer 306 is arranged between the two isolation plates 305 and is integrated with the two isolation plates 305. In construction step 4), after the isolation cavity is filled with a backfill layer 303, the backfill layer 303 presses against the isolation plates 305, and simultaneously squeezes the elastic layer 306 to compress and deform.

[0056] By forming the elastic layer 306 in the two isolation plates 305 , when the two isolation plates 305 are pressed toward each other, the elastic layer 306 is squeezed and exhibits planar compression deformation, thereby isolating and buffering the vibration.

[0057] In this embodiment, in construction step 3), a plurality of positioning posts 3061 are provided in the elastic layer 306. The plurality of positioning posts 3061 are arranged along the thickness direction of the elastic layer 306 and are wrapped inside the elastic layer 306. Positioning intervals 3062 are defined between the ends of the plurality of positioning posts 3061 and the isolation plate 305. The positioning intervals 3062 of the plurality of positioning posts 3061 are different.

[0058] In the preparation step 4), after the isolation cavity is filled with the backfill layer 303, the isolation plate 305 is squeezed by the backfill layer 303, and the elastic layer 306 is squeezed and deformed synchronously, and the positioning interval 3062 is reduced.

[0059] By adding a plurality of positioning posts 3061 in the elastic layer 306, the integrity and deformation consistency of the elastic layer 306 can be maintained, and the deformation direction of the elastic layer 306 can be guided. When the elastic layer 306 is in compression deformation, the elastic layer 306 is prevented from dislocating, thereby maintaining the stability of the vibration reduction structure 300.

[0060] In this embodiment, in construction step 3), a hollow tube 304 is lowered into the isolation cavity. The interior of the hollow tube 304 has a hollow cavity. The outer periphery of the hollow tube 304 is provided with a plurality of peripheral holes, and the peripheral holes laterally penetrate the hollow tube 304. The bottom of the hollow tube 304 is placed in the isolation cavity, and the top of the hollow tube 304 extends to the top of the isolation cavity to form an upper section 3041. In construction step 4), after the isolation cavity is filled with solidified soil, the solidified soil simultaneously fills the hollow cavity.

[0061] By arranging the hollow tube 304 in the isolation cavity and simultaneously filling the hollow tube 304 with solidified soil, a mixed arrangement of the hollow tube 304 and the solidified soil is formed in the isolation cavity, which can further enhance the isolation effect of vibration; in addition, the top of the hollow tube 304 forms an upper section 3041, which extends to the top of the isolation cavity, and can buffer and reduce the vibration.

[0062] In this embodiment, in construction step 4), after the vibration-damping structure 300 is formed, a concrete slab 400 is arranged on the top of the fertilizer trough. The bottom of the concrete slab 400 has an elastic bottom layer 401, which presses against the top of the vibration-damping structure 300 and is integrated with the vibration-damping structure 300; the upper section 3041 passes through the bottom layer 401 and is embedded in the concrete slab 400 and is integrated with the concrete slab 400.

[0063] During the process of isolating and buffering vibrations, part of the vibration is transmitted to the upper section 3041 of the hollow tube 304 by the backfill layer 303. At this time, the vibrations can be buffered and absorbed by the concrete slab 400 and the elastic bottom layer 401, thereby isolating and buffering the vibrations. In addition, by arranging the concrete slab 400, the top of the vibration-damping structure 300 can be reinforced.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
