Description

Technical Field

[0001] The invention belongs to the field of building construction and relates to a pile foundation bridge deck connection structure adjacent to an embankment. Background Art

[0002] In the field of bridge engineering, the bridge deck connection structure adjacent to the embankment has always been a key link in design and construction. The geological conditions near the embankment are complex and changeable, the soil bearing capacity is uneven, and it is often affected by natural factors such as water erosion and tidal changes. This places extremely high demands on the stability and safety of the bridge deck.

[0003] Traditional bridge deck connection structures often have many shortcomings near embankments. On the one hand, due to the uncertainty of soil conditions near the embankment, traditional pile foundation arrangements are difficult to adapt to the complex geological environment, resulting in uneven stress on the pile foundations, which can easily cause uneven settlement of the bridge deck, thereby affecting the overall stability and service life of the bridge. On the other hand, traditional structures perform poorly in terms of shock absorption and energy dissipation. When subjected to external forces such as vehicle loads, wind or earthquakes, the bridge deck lacks an effective energy dissipation mechanism and is prone to excessive vibration and deformation, posing a threat to driving safety and the bridge structure itself.

[0004] Furthermore, traditional bridge deck connection structures have limitations in adjusting the tilt angle of the bearing platform. In actual construction, due to uneven terrain or construction errors, the flatness of the bridge deck is often difficult to ensure. Traditional structures often lack flexible adjustment mechanisms, making it difficult to precisely control the tilt angle of the bearing platform. This, to a certain extent, affects the construction quality and subsequent performance of the bridge. Summary of the Invention

DETAILED DESCRIPTION

[0038] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention.

[0039] like Figure 1-Figure 7 The illustrated structure shows a pile foundation and bridge deck connection structure adjacent to an embankment. A first pile foundation 2 and multiple second pile foundations 3 are arranged within the embankment 1. The multiple second pile foundations 3 are arranged in a ring around the first pile foundation 2, with their tops tilted 2 to 5 degrees toward the first pile foundation 2. This tilt angle is precisely calculated to ensure that the pile foundations work together effectively under load, sharing the weight of the bridge deck. A casting platform 4 is cast on the tops of both the first and second pile foundations 2, 3. This casting platform 4 is constructed of high-strength concrete, and its top end forms an extension platform 5 for secure connection to the bridge deck.

[0040] A first connecting seat 21 is installed at the top of the first pile foundation 2. A lower connecting plate 66 of the support seat 6 slides within the first connecting seat 21. The lower connecting plate 66 is made of high-strength steel plate, with multiple fixed blocks 67 fixed to its outer wall. A common connecting rod 68 is rotatably mounted between adjacent fixed blocks 67. The connecting rod 68 is made of high-strength alloy steel, and its diameter and length are determined by the design load and bridge deck dimensions.

[0041] The support base 6 also includes a connecting platform 63 welded to the top of a lower connecting plate 66. A ball groove 64 is defined at the top of the connecting platform 63, into which a semi-circular ball 62 is embedded. The semi-circular ball 62 is constructed of high-strength alloy steel and is sheathed with a cover plate 65 bolted to the connecting platform 63 to prevent it from falling off. The top of the semi-circular ball 62 is connected to the supporting platform 7 via an upper connecting plate 61. The supporting platform 7 is constructed of high-strength steel and is designed to directly support the bridge deck.

[0042] The outer wall of the lower connecting plate 66 is also sheathed with a second rubber pad 69 located below the fixing block 67. The second rubber pad 69 is made of highly elastic rubber material, and its bottom contacts the first connecting seat 21. When the bridge deck is subjected to external forces, the second rubber pad 69 can absorb some of the energy, thereby playing a role in energy dissipation and shock absorption.

[0043] A second connecting base 31, made of high-strength steel, is fixed above the second pile foundation 3. A concave block 32 is fixed to the top of the second connecting base 31, and a guide rod 33 is fixed within the concave block 32. A sliding base 35, located within the concave block 32, is slidably mounted on the outer wall of the guide rod 33. The other end of the connecting rod 68 is rotatably mounted within the sliding base 35.

[0044] The outer wall of the guide rod 33 is further sleeved with two second rubber blocks 34 located within the concave block 32, with the sliding seat 35 located between the two second rubber blocks 34. When the connecting rod 68 is subjected to force, the sliding seat 35 slides on the guide rod 33, and the second rubber blocks 34 act as a buffer and shock absorber, thereby protecting the connecting rod 68 and the concave block 32 from damage.

[0045] A damping rod 8 is mounted on top of the concave block 32. This hydraulic damper has a damping coefficient determined by the design load and shock absorption requirements. The top end of the piston end 9 within the damping rod 8 is connected to the bearing platform 7. When the bridge deck is subjected to external forces, the damping rod 8 absorbs and dissipates some of the energy, reducing the vibration amplitude of the bridge deck.

[0046] The damping rod 8 is equipped with a fixing mechanism for securing the piston end 9. This fixing mechanism includes a fixing plate 10, which is fixedly mounted on the top of the damping rod 8. The fixing plate 10 is made of high-strength steel. The top of the fixing plate 10 is provided with multiple chute grooves 19, within which slide blocks 191 slide. A clamping block 11 is fixed to the top of the slide block 191. The outer wall of the piston end 9 is provided with multiple slots 20 corresponding to the clamping blocks 11. The number and spacing of the slots 20 are determined by the telescopic length of the piston end 9 and the required fixing requirements.

[0047] A drive assembly is housed within the fixed disk 10, securing the position of the piston end 9. This assembly includes a rotating disk 12, which rotates within the fixed disk 10 via bearings. A spiral strip 13 is integrally formed on the top of the rotating disk 12. A slider 191 has an arcuate groove 192 at its bottom, which mates with the spiral strip 13. When the rotating disk 12 rotates, the spiral strip 13 interacts with the arcuate groove 192, pushing the slider 191 within the slide 19, causing the block 11 to engage or disengage the slot 20, thereby securing the position of the piston end 9.

[0048] A toothed disc 14 is fixed to the bottom of rotating disc 12, while a second rotating base 15 is fixed to the bottom of fixed disc 10. A gear 16, which meshes with toothed disc 14, is connected to one side of second rotating base 15 via a rotating shaft. A mounting base 17 is welded to one side of fixed disc 10. A motor 18 is bolted to mounting base 17, with the output end of motor 18 plugged into the rotating shaft. To adjust the position of piston end 9, motor 18 is started, which rotates gear 16 via the rotating shaft, thereby rotating toothed disc 14 and rotating disc 12, ultimately securing the position of piston end 9.

[0049] A first fixed seat 36 is welded to the top of the sliding seat 35. A first universal ball 37 is embedded within this first fixed seat 36 and fixed to the bottom end of the damping rod 8. A second universal ball 92 is fixed to the top of the piston end 9. A second fixed seat 91, corresponding to this universal ball 92, is fixed to the bottom of the support platform 7. This universal ball connection allows the damping rod 8 and piston end 9 to rotate freely in multiple directions to accommodate deformation of the bridge deck under varying load conditions.

[0050] The construction process of the pile foundation bridge deck connection structure adjacent to the embankment includes the following steps:

[0051] S1, using a pile driver to press the first pile foundation 2 and the second pile foundation 3 into the embankment 1, and controlling the inclination of the second pile foundation 3;

[0052] Casting the casting platform 4 so that the top of the casting platform 4 forms an extension platform 5, and welding the first connecting seat 21 and the second connecting seat 31 to the steel bars at the top of the casting platform 4;

[0053] Weld the concave block 32 to the second connecting seat 31, insert the lower connecting plate 66 into the first connecting seat 21, and install one end of the connecting rod 68 between the two adjacent fixing blocks 67;

[0054] S2. Weld the connecting platform 63 to the lower connecting plate 66, and use the cover plate 65 to confine the semicircular ball 62 in the ball groove 64. Fix the supporting platform 7 to the top of the upper connecting plate 61, and fix the second fixing seat 91 to the bottom of the supporting platform 7.

[0055] According to the inclination angle of the bottom of the bridge deck, the inclination of the bearing platform 7 is adjusted. During the swinging process, the second universal ball 92 and the second fixing seat 91 can be used to drive the piston end 9 to move in the damping rod 8 until the inclination adjustment of the bearing platform 7 is completed. Then, the motor 18 is sequentially installed on the mounting seat 17, and the output end of the motor 18 is fixed in the gear 16 using a key pin;

[0056] S3. Start the motor 18 to drive the gear 16 to rotate. During the rotation of the gear 16, the toothed disc 14 can drive the rotating disk 12 to rotate. The rotation of the rotating disk 12 can drive the spiral bar 13 to rotate. During the rotation of the spiral bar 13, the arc groove 192 can drive the slider 191 to move in the slide groove 19, so that they approach each other until the block 11 is inserted into the corresponding slot 20. At this time, the inclination angle of the support platform 7 is fixed.

[0057] S4. Place the bridge deck on the bearing platform 7 and secure it with bolts. After securing, start the motor 18 to rotate in the reverse direction, driving the clamping block 11 to move outward, so that the clamping block 11 is released from the clamping slot 20. Then, hydraulic oil is filled into the damping rod 8 through the hydraulic station so that the pressure in the multiple damping rods 8 is the same.

[0058] When the bridge deck vibrates, it can drive the semicircular ball 62 to swing in the ball groove 64 and at the same time drive the lower connecting plate 66 to move downward. The downward movement of the lower connecting plate 66 can use the connecting rod 68 to drive the sliding seat 35 to move in the concave block 32, and squeeze the corresponding second rubber block 34, and at the same time squeeze the piston end 9 to move in the damping rod 8 to perform damping and shock absorption.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions, which should all be included in the scope of the claims of the present invention.
