All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0045] Example

[0046] The present invention will be further described below with reference to the accompanying drawings.

[0047] like Figures 1 to 6 As shown, this embodiment provides a new energy-absorbing and shock-absorbing foundation structure for a double-column bridge pier, comprising:

[0048] A foundation support module 1, the foundation support module 1 is composed of two foundations 11 and a U-shaped well 12 located between the two foundations 11, and a well cover 13 is provided on the U-shaped well 12;

[0049] Bridge piers 2, two of the bridge piers 2 are installed on each of the foundations 11 in a one-to-one correspondence;

[0050] The energy dissipation and shock absorption component 3 is installed in the U-shaped well 12 .

[0051] The working principle and beneficial effects of the above technical solution are:

[0052] The present invention discloses a novel energy-absorbing and shock-absorbing foundation structure for a double-column bridge pier. The foundation support module 1 consists of two foundations 11 and a U-shaped well 12 located between the two foundations 11. The bridge pier 2 is installed on the foundation 11, and the energy-absorbing and shock-absorbing component 3 is located in the U-shaped well 12. The present invention provides a novel energy-absorbing and shock-absorbing foundation structure for a double-column bridge pier. The manhole cover 13 realizes the closure of the U-shaped well 12, and the energy-absorbing and shock-absorbing component 3 is installed in the U-shaped well 12. After an earthquake, it is only necessary to open the manhole cover 13 to complete the replacement of the various components that constitute the energy-absorbing and shock-absorbing component 3, and the maintenance cost is low.

[0053] In one embodiment, the U-shaped well 12 is a reinforced concrete structure.

[0054] In one embodiment, the U-shaped well 12 is integrally connected and cast with the two foundations 11 .

[0055] The working principle of the above technical solution is:

[0056] The U-shaped well is a reinforced concrete structure, which is poured between the two foundations 11 and connected to the foundation 11 to form a closed space, which is closed by a well cover 13 on top.

[0057] In one embodiment, the energy dissipation and shock absorption component 3 includes:

[0058] A U-shaped liquid storage tank 31, the U-shaped liquid storage tank 31 is located in the U-shaped well 12, and the U-shaped liquid storage tank 31 stores flowing liquid;

[0059] A plate rubber bearing assembly, the plate rubber bearing assembly includes a plate rubber bearing 32, a plurality of the plate rubber bearings 32 are distributed in an array at the bottom of the U-shaped well 12, and the U-shaped liquid storage tank 31 is installed on the plate rubber bearing 32;

[0060] The inertia-type viscous damper 33 is connected between the inner wall of the U-shaped well 12 and the U-shaped liquid storage tank 31 .

[0061] The working principle and beneficial effects of the above technical solution are:

[0062] A U-shaped reservoir 31 filled with flowing liquid is arranged within the U-shaped well 12. The U-shaped reservoir 31 is placed on a plate-type rubber bearing assembly, which is placed at the bottom of the U-shaped well 12. An inertia-type viscous damper 33 is used to connect the inner wall of the U-shaped well 12 and the U-shaped reservoir 31. Under the action of an earthquake, the U-shaped reservoir 31 slides on the plate-type rubber bearing assembly, thereby stimulating the energy dissipation effect of the inertia-type viscous damper 33. At the same time, the flowing liquid in the U-shaped reservoir 31 also dissipates seismic energy. As a result, the new energy-dissipating and shock-absorbing foundation structure of the double-column bridge pier can achieve energy dissipation and shock absorption, reducing earthquake damage to the pier. Moreover, after an earthquake, the inertia-type viscous damper 33 and the U-shaped reservoir 31 are extremely convenient to replace, and the maintenance cost is low.

[0063] In one embodiment, the plate rubber support 32 is made of tetrafluoroethylene.

[0064] In one embodiment, the energy dissipation and shock absorption component 3 further includes:

[0065] An elastic support member is located at the bottom of the U-shaped well 12 , the U-shaped liquid storage tank 31 is installed on the elastic support member, and the elastic support member is located between adjacent plate-type rubber supports 32 .

[0066] The working principle of the above technical solution is:

[0067] The elastic support member is located at the bottom of the U-shaped well 12 and plays a role in assisting in supporting the U-shaped well 12 .

[0068] In one embodiment, the plate rubber bearing assembly further includes:

[0069] Transverse sliding rails 34, two of the transverse sliding rails 34 are installed at the bottom of the U-shaped well 12;

[0070] A support mounting seat 35 is slidably connected to the transverse slide rail 34. The support mounting seat 35 is provided with a support placement chamber 36 for placing the plate rubber bearing 32. A wedge-shaped limiting component for limiting the upper step surface of the plate rubber bearing 32 is symmetrically installed on the top of the support mounting seat 35. A limiting ring for limiting the lower step surface of the plate rubber bearing 32 is installed at the bottom of the support placement chamber 36.

[0072] The support replacement assembly is installed against the U-shaped liquid storage tank 31, and the transverse slide rail 34 extends into the support replacement assembly. The support replacement assembly is used to replace the plate rubber bearing 32 in the support placement chamber 36. The support replacement assembly is equipped with a push rod 37 for adapting to the wedge-shaped limit assembly.

[0073] The working principle and beneficial effects of the above technical solution are:

[0074] When it is necessary to regularly replace the plate rubber support 32 located at the bottom of the U-shaped liquid storage tank 31, the support replacement assembly works, and the support mounting seat 35 drives the plate rubber support 32 to temporarily detach from the bottom of the U-shaped liquid storage tank 31 and move along the transverse slide rail 34 into the support replacement assembly. After the push rod 37 opens the wedge-shaped limit assembly, the replacement of the plate rubber support 32 located in the support placement chamber 36 is completed, and then the elastic reset assembly works, thereby driving the replaced plate rubber support 32 located in the support placement chamber 36 along the transverse slide rail 34 to return to the bottom of the U-shaped liquid storage tank 31. When the plate rubber support 32 is replaced, the elastic support plays a role in auxiliary support of the U-shaped liquid storage tank 31.

[0075] In one embodiment, the elastic reset assembly comprises:

[0076] A reset seat 38 , the reset seat 38 being installed at the bottom of the U-shaped well 12 ;

[0077] A reset shaft, the reset shaft being rotatably mounted in the reset seat 38;

[0078] a reset coil spring, the reset coil spring being mounted on the reset shaft;

[0079] A reset rotary disc 39, the reset rotary disc 39 being mounted on the reset shaft;

[0080] An elastic retractable rope 30 , one end of which is wound around the reset turntable 39 , and the other end of which is connected to the support mounting seat 35 .

[0081] The beneficial effects of the above technical solution are:

[0082] When the support replacement assembly is working, the support mounting seat 35 drives the plate rubber support 32 to temporarily detach from the bottom end of the U-shaped liquid storage tank 31 and move into the support replacement assembly along the transverse slide rail 34. While the elastic retractable rope 30 connected to the support mounting seat 35 is stretched, it drives the reset turntable 39 connected to the elastic retractable rope 30 to rotate on the reset seat 38. At this time, the reset spring installed on the reset shaft is under force. When the support replacement assembly works in the reverse direction, under the dual action of the reset spring resetting and the elastic retractable rope 30 contracting, the support mounting seat 35 quickly returns to the bottom end of the U-shaped liquid storage tank 31.

[0083] In one embodiment, the support replacement assembly includes:

[0084] A replacement box 41 is installed adjacent to the U-shaped liquid storage tank 31 . A support drop chamber 44 and a support installation chamber 45 are located within the replacement box 41 and separated by a vertical plate 43 . The ejector rod 37 is installed on the inner wall of the support installation chamber 45 .

[0085] An opening 42 is formed on the replacement box 41 and communicates with the support drop chamber 44 . The transverse slide rail 34 extends from the opening 42 into the replacement box 41 . The support mounting seat 35 slides from the opening 42 into the replacement box 41 .

[0086] A chain-driven lifting unit 46 is installed in the support mounting chamber 45 . The chain-driven lifting unit 46 is connected between a weight block 47 and the support mounting seat 35 . The weight block 47 falls along the vertical plate 43 .

[0087] The oblique guide block unit is installed in the support falling chamber 44, and the oblique guide block unit is connected to the weight block 47. The oblique guide block unit includes an oblique guide block 49, and the oblique guide block 49 guides the plate rubber bearing 32 to slide onto the bearing mounting seat 35, and the weight block 47 presses the plate rubber bearing 32 into the bearing placement chamber 36.

[0088] The working principle and beneficial effects of the above technical solution are:

[0089] The chain drive lifting unit 46 works, thereby driving the weight block 47 connected to the chain drive lifting unit 46 and the support mounting seat 35 to move synchronously. The support mounting seat 35 drives the plate rubber support 32 to temporarily separate from the bottom end of the U-shaped liquid storage tank 31 and move along the transverse slide rail 34 from the opening 42 to the replacement box 41 and is located under the weight block 47. At this time, the top rod 37 opens the wedge-shaped limit assembly, and the chain drive lifting unit 46 releases the pulling force on the weight block 47, and the weight block 47 falls vertically under the action of gravity, thereby driving the inclined guide block unit connected to the weight block 47 to fall synchronously. When the inclined guide block 49 falls, the plate rubber support 32 located in the support falling chamber 44 and against the inclined end of the inclined guide block 49 slides from under the vertical plate 43 and slides along the inclined end of the inclined guide block 49 to the top of the support mounting seat 35. At this time, as the weight block 47 falls, the new plate rubber support 32 is The rubber bearing 32 is pressed into the bearing placement chamber 36. Under the action of pressure, the lower step surface of the plate rubber bearing 32 disengages from the limiting ring, thereby causing the old plate rubber bearing 32 originally located in the bearing placement chamber 36 to fall off from the bottom end of the bearing mounting seat 35 and be collected at the bottom of the replacement box 41. At this time, the chain drive lifting unit 46 works in reverse, and the weight block 47 and the oblique guide block 49 are quickly lifted. The weight block 47 releases the pressure on the new plate rubber bearing 32 located in the bearing placement chamber 36, and the oblique guide block 49 is quickly lifted, thereby utilizing the cooperation between the inclined end of the oblique guide block 49 and the bottom end of the vertical plate 43 to complete the limitation of the new plate rubber bearing 32 located in the bearing drop chamber 44. Under the dual action of the reset spring and the contraction of the elastic retractable rope 30, the bearing mounting seat 35 quickly returns to the bottom end of the U-shaped liquid storage tank 31, thereby completing the replacement of the new plate rubber bearing 32.

[0090] In one embodiment, the chain drive lifting unit 46 includes:

[0095] The drive motor 53 installed at the top of the support mounting chamber 45 works, thereby driving the transmission sprocket installed at the output end of the drive motor 53 to rotate, thereby driving the transmission chain 51 running on the transmission sprocket and the guide sprocket 52, and thus realizing the synchronous movement of the weight block 47 connected to the two ends of the transmission chain 51 and the support mounting seat 35. The weight block 47 performs free fall motion, and the support mounting seat 35 performs horizontal sliding along the transverse slide rail 34.

[0096] In one embodiment, the oblique guide block unit further comprises:

[0097] A guide plate 54, the guide plate 54 slides against the inner wall of the support drop chamber 44, and the oblique guide block 49 is mounted on the guide plate 54;

[0098] The connecting frame 55 is connected between the guide plate 54 and the weight block 47 . The vertical plate 43 is provided with a vertical slide groove for facilitating the sliding of the connecting frame 55 . The connecting frame 55 is arranged to avoid the plate rubber support 32 .

When the inclined guide block 49 falls, the plate rubber bearing 32 located in the support falling chamber 44 and against the inclined end of the inclined guide block 49 slides from under the vertical plate 43, and slides along the inclined end of the inclined guide block 49 to the top of the support mounting seat 35.

[0101] In one embodiment, the bottom end of the replacement box 41 is open, and an outlet 56 is provided at the side end of the replacement box 41 away from the opening 42. A preset distance is left between the transverse slide rail 34 and the bottom of the replacement box 41. A one-way driven oblique hook assembly 57 is installed on the transmission chain 51. The oblique hook assembly 57 is used to drive the plate rubber support 32 located at the bottom of the replacement box 41 to slide toward the outlet 56. A support placement groove is installed at the top of the replacement box 41, and the bottom end of the support placement groove is inclined. A plurality of plate rubber supports 32 are placed side by side in the support placement groove. A discharge port 58 connected to the support placement groove is opened at the top of the replacement box 41. The lower end of the support placement groove is arranged close to the discharge port 58, and a guide cylinder 59 connected to the discharge port 58 is installed in the support drop chamber 44.

[0102] The working principle and beneficial effects of the above technical solution are:

[0103] The driving motor 53 installed on the top of the support installation chamber 45 works, thereby driving the transmission sprocket installed on the output end of the driving motor 53 to rotate, thereby driving the movement of the transmission chain 51 running on the transmission sprocket and the guide sprocket 52, thereby realizing the synchronous movement of the weight block 47 connected to both ends of the transmission chain 51 and the support installation seat 35, and the support installation seat 35 drives the plate rubber support 32 to temporarily separate from the bottom end of the U-shaped liquid storage tank 31, and move from the opening 42 to the replacement box 41 along the transverse slide rail 34, and the weight block 47 connected to the transmission chain 51 is driven by the support installation seat 35. The oblique hook assembly 57 hooks off the old plate rubber support 32 at the bottom of the replacement box 41 and sends the replacement box 41 out from the outlet 56, thereby facilitating the weight block 47 to complete the pressing out of the plate rubber support 32 located in the support placement chamber 36. The oblique hook assembly 57 can only rotate counterclockwise in one direction, that is, the oblique hook assembly 57 can only drive the old plate rubber support 32 at the bottom of the replacement box 41 to move toward the outlet 56, but cannot move the old plate rubber support 32 at the bottom of the replacement box 41 toward the inlet 42.
