[0037] At present, most bridge abutments and pier projects require the use of a tie rod formwork system when pouring concrete.

[0038] In the prior art, in projects, the tie rod holes of the formwork are usually processed by directly passing the tie rods through the formwork. Since the fit between the tie rods and the tie rod holes of the formwork is poor, leakage will occur at the tie rod holes when concrete is poured, which in turn leads to honeycombed surface after the concrete is poured and formed, resulting in poor appearance quality.

[0039] The following is a detailed description of the technical solution of the present application and how the technical solution of the present application solves the above technical problems with specific embodiments. It should be noted that the following implementations can refer to, draw on or combine with each other, and the same terms, similar features and similar implementation steps in different implementations will not be described repeatedly.

The side of the first section 11 close to the second section 12 is fitted with the template 3 on one side of the tie rod hole, and the side of the third section 13 close to the second section 12 is fitted with the template 3 on the other side of the tie rod hole. The fitting includes contact, abutment, etc., so that the template 3 circumferentially of the tie rod hole is clamped between the first section 11 and the third section 13, and the tie rod 2 is inserted into the second section 12, so that the tie rod 2 and the tie rod hole of the template 3 are tightly fitted, which can effectively prevent the problem of leakage at the tie rod hole position when pouring concrete 4, improve the pouring quality of concrete 4, and improve the appearance quality of concrete 4 after pouring.

[0043] Optionally, the material of the sealing ring includes elastic materials such as rubber. Since the sealing ring 10 is elastic, the sealing ring 10 can adapt to the deformation of the template 3 and the movement or deformation of the tie rod 2, so that the tie rod 2 and the tie rod hole of the template 3 always maintain a good fit, thereby avoiding the poor fit between the tie rod 2 and the tie rod hole of the template 3 due to the movement or deformation of the tie rod 2 and the deformation of the template 3, resulting in leakage at the tie rod hole.

[0044] Optionally, in the embodiment of the present application, the pull rod 2 includes a PVC pipe or the like. It should be noted that: Figure 4-5 In the figure, the dotted line between the first segment 11, the second segment 12, and the third segment 13 is used to distinguish the positions of the first segment 11, the second segment 12, and the third segment 13, and does not actually exist.

[0047] In the embodiment of the present application, the outer diameter of the first section 11 gradually decreases along the direction in which the first section 11 moves away from the second section 12; the side of the first section 11 away from the second section 12 has a smaller outer diameter, which facilitates the first section 11 to pass through the tie rod hole, thereby fitting with the template 3 on one side of the tie rod hole.

[0048] Optionally, in one embodiment of the present application, Figure 3-4 As shown, along the direction where the third section 13 is away from the second section 12 , the outer diameter of the third section 13 gradually decreases.

In the present application, the third section 13 is set to have the largest outer diameter on the side that fits with the template 3 on the other side of the tie rod hole, so that there is a larger contact area between the third section 13 and the template 3, so that the third section 13 and the template 3 on the other side of the tie rod hole have a better fit effect, the tie rod 2 passes through the third section 13, the inner diameter of the third section 13 is smaller than the diameter of the tie rod 2, and the third section 13 and the tie rod 2 are interference fitted, so that the tie rod 2 and the tie rod hole have a better fit effect, which prevents the concrete 4 from being exposed from the tie rod hole during the pouring process, thereby improving the pouring quality of the concrete 4.

[0050] In the embodiment of the present application, the outer diameter of the third section 13 gradually decreases along the direction in which the third section 13 moves away from the second section 12; the side of the third section 13 away from the second section 12 has a smaller outer diameter, which facilitates the third section 13 to pass through the tie rod hole, thereby fitting with the template 3 on the other side of the tie rod hole.

The outer diameter of the first section 11 is larger than the outer diameter of the second section 12, and the outer diameter of the third section 13 is larger than the outer diameter of the second section 12, so that the outer diameter of the first section 11 is larger than the diameter of the tie rod hole, and the outer diameter of the third section 13 is larger than the diameter of the tie rod hole. The template 3 around the tie rod hole is clamped between the first section 11 and the third section 13, so that the sealing ring 10 can fit tightly on the template 3 around the tie rod hole, thereby forming an effective sealing layer, which can effectively prevent leakage during concrete 4 pouring, improve construction efficiency, reduce construction costs, and improve the appearance quality of concrete 4 after pouring.

[0055] Optionally, in one embodiment of the present application, Figure 3-4 As shown, along the direction from the first section 11 to the second section 12, the inner diameter of the first section 11 gradually increases.

[0060] In the embodiment of the present application, the minimum inner diameter of the first section 11 and the inner diameter of the third section 13 are both equal to or slightly larger than the diameter of the tie rod hole, so that the first section 11 and the third section 13 are both interference fitted with the tie rod hole, so that the first section 11 and the third section 13 are both tightly fitted with the tie rod hole. The outer diameter of the first section 11 and the outer diameter of the third section 13 are both larger than the diameter of the tie rod hole, so as to avoid the sealing ring 10 falling off from the tie rod hole due to the impact force of the concrete 4 when pouring the concrete 4, resulting in leakage at the tie rod hole.

[0062] In the embodiment of the present application, the outer diameter of the first section 11 is set to be the same as the outer diameter of the third section 13, so that the manufacturing process of the sealing ring 10 is simple, thereby saving costs. It should be noted that the outer diameter of the first section 11 may not be equal to the outer diameter of the third section 13, as long as the outer diameter of the first section 11 and the outer diameter of the third section 13 are both larger than the diameter of the tie rod hole.

[0063] Optionally, in one embodiment of the present application, Figure 3-4 As shown, in the axial cross section of the sealing ring 10 , the template 3 in the circumferential direction of the tie rod hole is clamped between the first section 11 and the third section 13 .
