DETAILED DESCRIPTION

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0019] [Assembled bridge piers], which consist of an upper pier A and a lower pier B. During construction, the upper pier A and the lower pier B are spliced ​​together. After the splicing is completed, high pressure pouring is performed in the splicing gap between the upper pier A and the lower pier B and in the embedded parts. The lower pier B is provided with steel bars spliced ​​with the upper pier A, and the upper pier A is provided with embedded parts. The embedded parts are provided with steel bar holes that match the steel bars of the lower pier B, and the top of the embedded parts is provided with a connected flow channel and pouring hole.

[0020] like Figure 1-4 As shown, a prefabricated bridge construction device includes an input pipe mechanism 1, a fixing member 2 and a return pipe 3. The fixing member 2 fixes the input pipe mechanism 1 and the return pipe 3 at the pier joint of the prefabricated bridge; the fixing member 2 is fixed to the joint seam of the upper pier A and the lower pier B. On the one hand, it can prevent the upper pier A from being offset due to vibration at the construction site, and on the other hand, it can block the pier joint seam to prevent the poured concrete from overflowing. The input pipe mechanism 1 is inserted into the pouring hole and the pouring hole is sealed with the rubber plug 12 thereon.

[0021] It should be further explained that the reflux pipe 3 is connected to the input end of the input pipe mechanism 1; the input pipe mechanism 1 is provided with an input pipe 11 and a rubber plug 12, the rubber plug 12 is sleeved outside the input pipe 11, the input pipe 11 is inserted into the casting hole, the rubber plug 12 is blocked at the casting hole when in use, and can only reflux from the first reflux pipe 31; the input pipe 11 is provided with a first reflux hole 110 and a second reflux hole 111, the first reflux hole 110 is located above and in front of the second reflux hole 111; the reflux pipe 3 includes a first reflux pipe 31 and a second reflux pipe 32, the first reflux pipe 31 is located inside the input pipe 11 and connected to the first reflux hole 110, and the first reflux pipe 31 is also inserted into the casting hole following the input pipe 11. The second reflux pipe 32 is located on the joint between the upper pier A and the lower pier B, and is connected to the second reflux hole 111. By arranging the return pipes 3 up and down, return flow is generated from both the joint gap and the casting hole, thereby avoiding the problems of uneven casting and internal bubble generation, thereby improving the construction quality.

[0022] To be precise, the first reflux hole 110 and the second reflux hole 111 have the same shape. The first reflux hole 110 is provided with a slow flow chamber 113, a rapid reflux chamber 114 and a one-way sheet 115. The slow flow chamber 113 is connected to the rapid reflux chamber 114, and the reflux is achieved by changing the flow rate through the two chambers. The one-way sheet 115 is located between the rapid reflux chamber 114 and the inner cavity of the input pipe 11. The one-way sheet 115 is a rubber sheet with moderate softness, and its function is to prevent concrete from entering the reflux pipe 3 at the beginning of pouring. It is worth mentioning that some slow flow chambers 113 are provided with pressure relief holes, which are used to avoid bubbles.

[0023] Furthermore, a spring sheet 112 is provided inside the input pipe 11, and the spring sheet 112 is located between the first return pipe 31 and the pipe wall of the input pipe 11. To be precise, the spring sheet 112 is an arc-shaped rubber spring sheet, which makes the first return pipe 31 extend out of the input pipe 11 and then tilt up, so that it can better contact with the top of the flow channel of the embedded part, thereby ensuring uniform casting.

[0024] It should be noted that the end of the first reflux pipe 31 is tilted, and is provided with an anti-blocking hole 310 and an air leakage hole 311, the anti-blocking hole 310 is located at the end of the first reflux pipe 31, and the air leakage hole 311 is located behind the anti-blocking hole 310. The anti-blocking hole 310 is provided with a plurality of anti-blocking columns 312, and the plurality of anti-blocking columns 312 form a cone.

[0025] [Fixing method of the fixing part], the fixing part 2 is provided with a detachable sealing fixing ring 21 and a fixing plate, the sealing fixing ring 21 is wrapped around the joint of the bridge pier, the fixing plate is located on the outside of the sealing fixing ring 21, and a screw is used to clamp it at the joint of the assembled bridge pier; a through hole 210 is provided on the sealing fixing ring 21, and the second return pipe 32 passes through the through hole 210.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
