The traditional method uses mortar of equal strength for plugging, which has complex construction technology, is difficult to control the repair effect, and is easy to cause secondary pollution to the finished concrete surface. In addition, for piers and towers with many tie rod holes, large holes, and quasi-fair-faced concrete, the investment in personnel, equipment, and materials is large, and the appearance quality cannot be guaranteed.

[0003] Therefore, a new type of sealing structure for concrete tie rod holes is needed to improve the above problems. Utility Model Content

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0022] A new type of concrete tie rod hole sealing structure includes a sealing concrete block 101. The sealing concrete block 101 includes a main tower prefabricated sealing concrete block 1 and a pier body prefabricated sealing concrete block 2. The main tower prefabricated sealing concrete block 1 is inserted into the main tower conical nut tie rod hole, and the pier body prefabricated sealing concrete block 2 is inserted into the pier body nut tie rod hole.

[0023] In this embodiment, the outer structure of the prefabricated blocking concrete block 1 of the main tower is a truncated cone structure design, and the outer structure of the prefabricated blocking concrete block 2 of the pier body is a truncated cone structure design. The prefabricated blocking concrete block 1 of the main tower is connected to the tapered nut tie rod hole of the main tower by resin glue in a bonding structure, and the prefabricated blocking concrete block 2 of the pier body is connected to the nut tie rod hole of the pier body by resin glue in a bonding structure. The outer structure of the prefabricated blocking concrete block 1 of the main tower is adapted to the outer structure of the tapered nut tie rod hole of the main tower, and the outer structure of the prefabricated blocking concrete block 2 of the pier body is adapted to the outer structure of the nut tie rod hole of the pier body. This process structure can realize the rapid construction of tie rod hole blocking, which is easy to operate, efficient and controllable. After the tie rod hole is blocked, the appearance quality is good, and there is no large color difference as a whole. The blocking blocks are bonded with resin glue, which has good durability and will not fall off. The safety is high during the later operation period. The tie rod hole blocking adopts concrete block + resin glue, and the finished product can be mass-produced and used, which has a high value of promotion and use.

[0024] The working process of the utility model is as follows: first, when the tie rod hole is blocked, a contoured concrete block is prefabricated in advance according to the size of the tie rod hole. The size of the concrete block is 0.5 mm smaller than the size of the tie rod hole. After removing the template, a chisel and a hammer are used to chisel 3 cm around the tie rod head into the concrete by 2 to 3 cm to form a conical groove;

[0025] When plugging the taper nut tie rod hole of the main tower, use a special vise to slowly rotate and take out the taper nut, remove the residue in the taper hole, then apply resin glue to the surface of the taper nut profiling concrete block, and then insert the main tower prefabricated plugging concrete block 1 into the taper nut tie rod hole of the main tower. Finally, mix the concrete mortar in advance, smooth and modify the surface of the filled tie rod hole, and the plugging of the taper nut tie rod hole of the main tower can be completed.

[0026] When plugging the nut tie rod hole of the pier body, first use an electric drill and a wire twister to reach into the tie rod hole to cut off 5 cm of the end PVC and remove the residue in the hole. Then, apply resin glue on the surface of the concrete block shaped like the tie rod hole of the PVC pipe. Finally, insert the prefabricated plugging concrete block 2 of the pier body into the nut tie rod hole of the pier body and install it. Finally, mix the concrete mortar in advance, smooth and modify the surface of the filled tie rod hole, and the plugging of the nut tie rod hole of the pier body can be completed. The new plugging method is easy to operate, efficient, and controllable. After the new plugging method is used, the appearance quality is good and can meet the requirements of fair-faced concrete. In addition, the new plugging method has a simple process and can be operated by one person. It requires less personnel and equipment, and the concrete blocks can be mass-produced.
