DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be combined with the technical solution in the embodiments of the utility model for a clear and complete description. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The viaduct pile body support includes a pile body 1 and a bridge deck 2. The pile body 1 and the bridge deck 2 are fixedly connected via a shock-absorbing base 3. The surface of the pile body 1 is provided with a support structure that can provide reinforced support for the bridge deck 2. The support structure is composed of a fixed component arranged on the surface of the pile body 1 and a lifting component arranged on both sides of the fixed component.

[0022] The fixing assembly includes a first clamp 4 and a second clamp 5, which are assembled as a whole by fixing bolts 6. A bushing 15 is fixedly installed at the lower ends of the first clamp 4 and the second clamp 5. The inner diameter of the bushing 15 is adapted to the outer diameter of the pile body 1. When the first clamp 4 and the second clamp 5 are assembled as a whole by fixing bolts 6, the bushing 15 will clamp the pile body 1, so that the first clamp 4 and the second clamp 5 can be clamped on the surface of the pile body 1.

[0023] The surfaces of the first clamp 4 and the second clamp 5 are both provided with through holes, the inner walls of the through holes are provided with threaded pull rods 7, the surfaces of the threaded pull rods 7 are threadedly connected with fixing nuts 8, and the inner annular surfaces of the first clamp 4 and the second clamp 5 are both equidistantly fixedly installed with multiple reinforcing pull plates 13. When the first clamp 4 and the second clamp 5 are clamped on the surface of the pile body 1, the reinforcing pull plates 13 will contact the surface of the pile body 1, and then the expansion bolts are embedded in the surface of the pile body 1, and then the threaded pull rods 7 can be fixed to the surface of the pile body 1 using the expansion bolts.

[0024] The lifting assembly includes a lifting frame 9 which is fixedly mounted on the outer annular surfaces of the first clamp 4 and the second clamp 5 respectively. A grouting cavity 10 is provided inside the lifting frame 9, and the inner annular surfaces of the first clamp 4 and the second clamp 5 are provided with through grooves which are interconnected with the grouting cavity 10. A grouting hole 11 is provided on the upper surface of the lifting frame 9. Concrete is injected into the grouting cavity 10 through the grouting hole 11, so that the grouting cavity 10 and the inner walls of the first clamp 4 and the second clamp 5 can be filled with concrete.

[0025] The surface of the lifting frame 9 is fixedly mounted with mounting bolts 12 that are compatible with the mounting holes of the external shock-absorbing base. The lower ends of the mounting bolts 12 extend into the interior of the grouting cavity 10. The connection strength of the mounting bolts 12 can be improved by filling concrete. A plurality of reinforcing rods 14 are fixedly mounted on the inner walls of the grouting cavity 10. The reinforcement rods 14 can be provided to improve the strength of the concrete in the grouting cavity 10, thereby improving the stability of the device.

[0026] When the concrete fills the grouting cavity 10, the inner walls of the first hoop 4 and the second hoop 5, the external shock-absorbing base is installed on the mounting bolts 12. The concrete can fill the inner walls of the grouting cavity 10, the first hoop 4 and the second hoop 5 to form an integral bracket, so that the bridge deck 2 can be supported by the lifting assembly, which increases the support points of the bridge deck 2 and shares the force, thereby avoiding the risk of the bridge deck 2 tilting and collapsing due to uneven force on the bridge deck 2. When the concrete fills the inner walls of the grouting cavity 10, the first hoop 4 and the second hoop 5, the reinforcing plate 13 will increase the contact surface with the concrete, thereby improving the connection strength between the first hoop 4 and the second hoop 5 and the pile body 1.
