[0032] like Figures 1-4As shown, this embodiment provides a technical solution: a prefabricated diagonal brace for post-grouting of pile ends, comprising two prefabricated support plates 1, a connecting plate 11 is installed between the two prefabricated support plates 1, and the interior of the two prefabricated support plates 1 are provided with a mounting groove 12 for use with the connecting plate 11; a first diagonal brace mechanism 2 is installed on the top of one of the prefabricated support plates 1; a second diagonal brace mechanism 3 is installed on the top of the other prefabricated support plate 1, the second diagonal brace mechanism 3 includes a mounting rod 31, the top of the other prefabricated support plate 1 is fixedly connected to the mounting rod 31, the top of the mounting rod 31 is fixedly connected to a supporting column 32, the outer side of the supporting column 32 is sleeved with two limiting sleeves 33, the outer side of the supporting column 32 and the side away from the limiting sleeve 33 is rotatably connected with a first rotating plate 34 and a second rotating plate 35, the second rotating plate 35 is located below the first rotating plate 34, and the side away from the first rotating plate 34 and the second rotating plate 35 is sleeved There are diagonal bracing support sleeves 36, and a second limiting rotating shaft 37 is installed on the top of the two diagonal bracing support sleeves 36. One of the second limiting rotating shafts 37 passes through the second rotating plate 35 and is connected to the diagonal bracing support sleeve 36, and the other second limiting rotating shaft 37 passes through the first rotating plate 34 and is connected to the diagonal bracing support sleeve 36. The two prefabricated support plates 1 are reinforced by the two mounting side plates 14 and the first bolt holes 15, and the two prefabricated support plates 1 are reinforced and connected by the connecting plate 11. During actual operation, the first diagonal bracing mechanism 2 is used to perform a first diagonal bracing operation on site, and the second diagonal bracing mechanism 3 is used to perform a second diagonal bracing operation on site.

After the adjustment is completed, the auxiliary support plate 21 and the first limit rotating shaft 23 are locked by the locking rod to prevent the adjustment rotating plate 24 from being reset, thereby ensuring the secondary diagonal bracing operation;

[0042] The second positioning bolts 38 are used to limit the first rotating plate 34 on both sides after the rotation adjustment is completed, and the third positioning bolts 39 are used to limit the second rotating plate 35 on both sides after the rotation adjustment is completed, thereby providing normal protection for the first rotating plate 34 and the second rotating plate 35 after the angle adjustment is completed, thereby extending the service life of the equipment;

[0043] The limiting sleeve 33 and the support column 32 are reinforced and installed by the fourth positioning bolt 4. The inside of the four first bolt holes 15 is installed with a fifth positioning bolt. The fifth positioning bolt is used in conjunction with the installation of the side plate 14 to facilitate the reinforcement installation of the prefabricated support plate 1 and the wall on one side during construction, thereby improving the stability of the equipment during use;

[0044] The two first mounting holes 13 are symmetrically distributed, and reinforcement steel bars are installed inside the two first mounting holes 13. The reinforcement steel bars are placed through the first mounting holes 13 to support the entire device;

[0045] The two prefabricated support plates 1 are reinforced by cooperating with the two mounting side plates 14 and the first bolt holes 15, and the two prefabricated support plates 1 are reinforced and connected by the connecting plate 11. During actual operation, a first diagonal bracing operation is performed on site through the first diagonal bracing mechanism 2, and a second diagonal bracing operation is performed on site through the second diagonal bracing mechanism 3. No electricity resources are used during the operation of the entire equipment, which saves the overall use and installation cost, and at the same time improves the support stability of the diagonal bracing. It can be applied to different working environments, improves the flexibility of the equipment, and solves the technical problems of the existing technology of single function and poor support stability of the diagonal bracing equipment.
