[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] See also Figure 1-4The utility model provides a post-grouting grouting installation pipe guide, comprising a grouting pipe 1, a guide plate 2 and a limiting sleeve 3 installed on the guide plate 2. The limiting sleeve 3 is provided with a slot 4 for allowing the end of the grouting pipe 1 to be inserted, and the end of the limiting sleeve 3 is provided with a blocking plate 5; further, the end of the grouting pipe 1 is inserted into the slot 4 and in close contact with the blocking plate 5; the guide plate 2 is preferably 200mm*200mm, 3-5mm thick hard steel; the limiting sleeve 3 is preferably a square tube with a length of 100mm, a side length of 35mm, and a wall thickness of 2-5mm, which ensures the structural strength of the guide plate 2 and the limiting sleeve 3 while avoiding the excessive mass of the guide causing a burden on the advancement of the grouting pipe 1 into the steel cage.

[0024] For details, please refer to Figure 3 An upwardly bent arc-shaped bending plate 6 is provided on the guide plate 2 away from the grouting pipe 1 at one end.

[0025] The post-grouting grouting installation pipe guide provided in this embodiment can reduce the friction between the end of the guide plate 2 and the binding wire or steel bar edge on the steel cage through the arc-shaped bending plate 6, reduce the occurrence rate of the guide plate 2 being stuck in the steel cage, improve the feeding smoothness of the guide, and further improve the installation and construction efficiency of the grouting pipe 1.

[0026] Example 2

[0027] Further optimize Example 1. For details, please refer to Figure 2-3 , also includes a first pull rope 7 and multiple hinges 8. The arc-shaped bending plate 6 is hinged to the guide plate 2 through multiple hinges 8. A buckle 9 is provided at the bottom bending part of the arc-shaped bending plate 6. One end of the first pull rope 7 is fixedly connected to the buckle 9.

[0028] For details, please refer to Figure 4 The hinge 8 is provided with a limit torsion spring 10; the two leaves on the hinge 8 are elastically connected by a limit torsion spring 10, and the opening angle of the hinge 8 is less than 90°.

[0029] Both the guide plate 2 and the arc-shaped bending plate 6 are provided with an embedding groove 11 , and the hinge 8 is embedded in the embedding groove 11 .

[0030] The post-grouting grouting installation pipe guide provided in this embodiment, when the guide plate 2 is stuck by the binding wire in the steel cage during the process of moving, the arc-shaped bending plate 6 is rotated downward around the end of the guide plate 2 by pulling the first pull rope 7 (please refer to Figure 3When the guide plate 2 is pulled away from the grouting pipe 1, the first pull rope 7 is released, and the guide plate 2 is automatically reset under the action of gravity. This is repeated so that the guide plate 2 can quickly break away from obstacles such as the binding wire. The limiting torsion spring 10 limits the opening angle of the hinge 8 and can prompt the curved bending plate 6 to reset itself after it is free from the force. The hinge 8 is installed in the embedded groove 11 to prevent the hinge 8 from being exposed, ensuring that the bottom of the guide plate 2 and the curved bending plate 6 are smooth, and preventing the hinge 8 from affecting the guide. Feeding causes scraping and obstruction; in another embodiment, the first pull rope 7 can be pulled to make the rotation angle of the arc-shaped bending plate 6 less than 45 degrees, and the end of the first pull rope 7 is fastened to the grouting pipe 1. At this time, the guide plate 2 is in an upward tilted state under the support of the arc-shaped bending plate 6, and the contact area between the guide plate 2 and the steel cage is reduced, and the bottom of the arc-shaped bending plate 6 is in contact with the steel cage line, which effectively reduces the contact area between the steel cage and the guide, thereby reducing the feed resistance of the guide, allowing the operator to more effortlessly deliver the grouting pipe 1 into the steel cage.

[0031] Example 3

[0032] For details, please refer to Figure 1 , also includes a second pull rope 12, a hole 13 is provided on the guide plate 2, one end of the second pull rope 12 passes through the hole 13 and is fixedly connected to the guide plate 2; further, the first pull rope 7 and the second pull rope 12 are preferably soft ropes.

[0033] There are multiple limiting sleeves 3 , and the multiple limiting sleeves 3 are evenly distributed on the guide plate 2 .

[0034] The limiting sleeve 3 is detachably mounted on the guide plate 2 by means of bolts.

[0035] The post-grouting grouting installation pipe guide provided in this embodiment can push and install multiple grouting pipes 1 into the steel cage at a time through multiple limiting sleeves 3, further improving the installation efficiency of the grouting pipes 1; when the diameter of the grouting pipe 1 changes, the limiting sleeves 3 of different sizes can be replaced to meet the installation and construction requirements of multiple grouting pipes 1; after the grouting pipe 1 is installed in place, when the other end of the steel cage is in a closed state, the guide can be detached from the end of the grouting pipe 1, and by pulling the second pull rope 12, the guide can be conveniently pulled out of the steel cage.

[0036] When in use, the guide plate 2 is placed horizontally in the steel cage, the end of the grouting pipe 1 is inserted into the slot 4 and contacts the baffle, pushing the grouting pipe 1 into the steel cage, the contact area between the guide plate 2 and the steel cage is increased, and the end of the grouting pipe 1 is effectively supported. The end of the grouting pipe 1 is supported and straightened, and the grouting pipe 1 is smoothly sent into the steel cage. The guide is detached from the end of the grouting pipe 1, and the second pull rope 12 is pulled to pull the guide out of the steel cage.
