[0025] The technical solution of this utility model will be clearly and completely described below through detailed embodiments and in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0026] Please refer to Figures 1-5 This embodiment provides a protective structure for the excavation opening of an anti-slide pile, including a rectangular locking ring 1 and a protective frame assembly 2 fixedly installed on the locking ring 1. The locking ring 1 is cast and fixed to the edge of the excavation opening 3 of the anti-slide pile, and the top surface of the locking ring 1 has several vertically distributed insertion holes 11. The protective frame assembly 2 is a metal frame structure arranged in a "U" shape. The protective frame assembly 2 has a side opening 21 on the side away from the slope surface, which facilitates personnel entry and exit from the pile hole and the removal of excavated soil and equipment. The bottom of the protective frame assembly 2 is fixed with several insertion rods 241 that are inserted and connected to the insertion holes 11. Because a spliced ​​protective frame assembly is used, and insertion holes are pre-arranged on the locking ring, the protective frame assembly can be quickly fixed by the cooperation of the insertion holes and insertion rods, which greatly improves the convenience of assembly and disassembly and facilitates recycling and reuse.

[0027] In some implementations, reference Figures 1-5The protective frame assembly 2 includes a first protective frame 22 located away from the side opening and two second protective frames 23 located on both sides of the first protective frame 22. A column 24 is provided between the first protective frame 22 and the second protective frame 23, and at the end of the second protective frame 23 away from the first protective frame 22. By providing the columns, the first protective frame and the second protective frame can be quickly spliced ​​and assembled to form a complete protective frame assembly.

[0028] In some specific implementation methods, refer to Figure 3 and Figure 4 Both ends of the first protective frame 22 and both ends of the second protective frame 23 are respectively provided with vertically distributed fixed edges 25. Each fixed edge 25 has a plurality of assembly holes 251. The side wall of the column 24 has threaded holes 242 corresponding to the assembly holes 251, and bolts 26 for locking are installed in the threaded holes 242. Thus, the first and second protective frames can be quickly assembled or disassembled using bolts.

[0029] As an improved implementation method, refer to Figure 1 , Figure 2 and Figure 4 The second protective frame 23 has a protective mesh plate 4 on the side facing the excavation opening 3 to cover the opening 3. The lower end of the protective mesh plate 4 is rotatably connected to the lower part of the second protective frame 23 via a pivot 41, and the upper end of the protective mesh plate 4 is snapped into the column 24 via a hook 42. In this way, during non-working hours, the excavation opening can be covered by flipping down the protective mesh plates on both sides, preventing accidental falls.

[0030] In some implementations, reference Figure 1 , Figure 2 and Figure 5 The upper part of the protective frame assembly 2 is provided with a hanging frame assembly 5 for installing a slag lifting device. Specifically, the hanging frame assembly 5 includes a hanging rod 51 and two fixed rods 52 respectively connected to both ends of the hanging rod 51. The hanging rod 51 is distributed parallel to the first protective frame 22, and the fixed rods 52 are distributed perpendicular to the hanging rod 51. Right-angle fasteners 53 are connected between the end of the hanging rod 51 and the middle of the fixed rod 52, and between the end of the fixed rod 52 and the upper part of the column 24. In this way, the column can be used as a support for force, and the hanging rod can be fixedly installed on the upper part of the column, so that simple lifting equipment such as an electric hoist can be hung to lift the slag.

[0031] In some specific implementation methods, refer to Figure 3 and Figure 4Both the first protective frame 22 and the second protective frame 23 include a frame portion 221, a baffle portion 222 and a grid portion 223. The frame portion 221 is rectangular, the baffle portion 222 is located at the lower part of the frame portion 221, and the grid portion 223 is located at the upper part of the frame portion 221.

[0032] In some specific implementation methods, refer to Figures 1-5 The column 24 is a hollow square steel pipe.

[0033] Specifically, as an example, the frame part 221 is made of square steel pipes welded together, the grid part 223 is made of straight steel bars welded together in a mutually perpendicular manner, and the baffle part 222 is made of steel plate cut together. The first protective frame 22 and the second protective frame 23 are prepared by welding and splicing.

[0034] As an improved implementation method, refer to Figures 1-5 The bottom of the protective frame assembly 2 is fixedly provided with a positioning plate 243 that is perpendicular to the insertion rod 241. Thus, when the insertion rod is inserted into the insertion hole, the positioning plate abuts against the top surface of the locking ring, thereby supporting the column.

[0035] In some implementations, such as Figure 5 As shown, in order to block the sun and prevent rainwater from falling into the pile hole, a sunshade and rainproof film 6 is provided on the top of the protective frame assembly 2. Specifically, as an example, the sunshade and rainproof film 6 is fixed to the top of the protective frame assembly 2 by plastic cable ties.

[0036] refer to Figures 1-5 In use, firstly, a locking ring 1 is cast along the edge of the excavation opening 3 of the anti-slide pile, and multiple insertion holes 11 are reserved. After the locking ring 1 hardens, the column 24 is inserted and fixed. Then, the first protective frame 22 and the second protective frame 23 are spliced ​​and installed to form a complete protective frame assembly 2 by locking bolts. After that, a fixing rod 52 and a hanging rod 51 are installed on the top of the column 24. Finally, the sunshade and rainproof film 6 is placed on the top of the protective frame assembly 2 to complete the installation of the anti-slide pile excavation opening protection structure, providing protection for the subsequent anti-slide pile excavation and pouring construction.
