It includes the design, construction and maintenance of piers, and mainly considers the stability, bearing capacity and durability of piers. Piers can be in different shapes such as cylindrical, rectangular or T-shaped, and commonly used materials include concrete, reinforced concrete and prestressed concrete.

The bridge pier of the utility model increases the connection distance between two adjacent beams by arranging spaced supporting bodies, reduces the number of bridge piers at the same length, and thus reduces the construction cost per unit length of the high-speed railway.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 2-Figure 3 The outside of the low-temperature layer 4 is fixedly connected with a carbon plate 5, and the outside of the carbon plate 5 is fixedly connected with a heat dissipation layer 6. The heat dissipation layer 6 is made of a copper plate. The copper plate here can effectively dissipate the heat inside the pier even in hot weather to prevent the pier from cracking. The outside of the heat dissipation layer 6 is fixedly connected with multiple inner plates 7. The outer side of the inner plate 7 is rotatably connected to two support rods 8. The other ends of the two support rods 8 are slidably connected to an outer plate 9. After the outer plate 9 is subjected to force, it will drive the two support rods 8 to rotate on the inner plate 7.

[0034] Reference Figure 3 The outer side of the outer plate 9 is fixedly connected with a rubber layer 10, and the rubber layer 10 here plays a buffering role to achieve the effect of unloading force, thereby reducing the impact force. The inner wall of the inner plate 7 is fixedly connected with two outer columns 11, and the inner wall of the outer column 11 is slidably connected with the inner column 12. The outer column 11 here provides a sliding space for the inner column 12, and the outer side wall of the inner column 12 is fixedly connected to the inner side wall of the outer plate 9. The inner side wall of the inner column 12 is fixedly connected to the limit block 13, and the limit block 13 here is used to prevent the inner column 12 from leaving the range of motion of the outer column 11;

[0035] Reference Figure 3The outside of the limit block 13 is slidably connected to the inner wall of the outer column 11, and a spring 14 is arranged inside the outer column 11. One end of the spring 14 is fixedly connected to one side of the inner wall of the outer column 11, and the other end of the spring 14 is fixedly connected to one side of the limit block 13.

[0036] Reference Figure 1 and Figure 4 , the four sides of the bottom end of the base plate 1 are fixedly connected with moisture-proof components, and the moisture-proof components include anti-corrosion plates 16, and the top ends of multiple anti-corrosion plates 16 are fixedly connected to the bottom end of the base plate 1, and the anti-corrosion plates 16 here are used to prevent the underground part from being corroded due to moisture.

The limiting strips 19 in the groove 17 here provide stable support for the spring 20.

[0037] Working principle: First, when the bridge pier under the high-speed railway construction is hit, the buffer layer (15) is first subjected to force, and then the force is transferred to the rubber layer (10), thereby reducing part of the force, and then the two support rods (8) are rotated on the inner plate (7) under the pressure of the outer plate (9), and the inner column (12) here will also slide inside the outer column (11), so that the limit block (13) squeezes the spring 1 (14) to generate a reaction force, thereby offsetting the external impact force and achieving a good protective effect. The carbon plate (5) here can absorb moisture to prevent moisture, and the low-temperature layer (4) here cooperates with the heat dissipation layer (6) to ensure that even in hot weather, the pier body 3 will not crack.

[0038] When it rains, the raindrops will flow to the side along the slide plate (18) after entering the soil. Similarly, when a flood occurs, the slide plate (18) transmits force to the limit strip (19), so that it squeezes the spring 2 (20) in the groove (17), thereby causing it to contract and generate a reaction force, effectively preventing the pier body 3 from being corroded, thereby increasing the life of the pier.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
