[0016] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] See Figure 1 This is a schematic diagram of the structure of the rapid positioning and binding platform for precast reinforcing bars of large jacking pipe sections in underground excavation projects, provided by an embodiment of this utility model. As shown in the figure, the rapid positioning and binding platform for precast reinforcing bars of large jacking pipe sections in underground excavation projects includes: a steel base box 1, several supporting uprights 2, hole support rods 3, and insertion connecting rods 4; wherein, Several supporting uprights 2 are arranged at circumferential intervals along the steel pad base 1, and each supporting upright 2 has an additional support along its length direction (e.g., ...). Figure 1 In the vertical direction shown, there are several spaced hole support rods 3, and each hole support rod 3 is provided with a fixing hole; the fixing connecting rod 4 is inserted into the fixing hole to provide a support surface for tying the reinforcing bars.

[0018] Specifically, the steel base 1 can be a square structure with multiple supporting uprights 2 along its outer edge. This embodiment uses eight uprights as an example, meaning each side edge has two spaced-apart supporting uprights 2 to provide a support platform. Each supporting upright 2 is vertically arranged, and its bottom end can be welded and fixed to the top wall of the steel base 1. Alternatively, it can be fixed using other connection methods, which are not limited in this embodiment. Each supporting upright 2 has multiple spaced and evenly arranged hole-position supporting rods 3 along its length (vertical direction). Each hole-position supporting rod 3 is horizontally installed on the supporting upright 2, and the spacing between each hole-position supporting rod 3 is the same and can be determined based on the rebar fixing spacing. The hole-position supporting rods 3 can be welded and fixed to the supporting upright 2. Furthermore, each hole-position supporting rod 3 has an insertion hole, into which a connecting rod 4 is inserted to provide a support surface for rebar binding. In this embodiment, the insertion connecting rod 4 is inserted into the insertion hole in a detachable manner, and the insertion position and insertion spacing of the insertion connecting rod 4 can be flexibly adjusted.

[0019] In this embodiment, the cross-section of the support rod 2 is an I-shaped or C-shaped structure, and the hole-position support rod 3 is arranged perpendicular to the flange plate of the support rod 2. The support rod 2 can be made of steel, i.e., an I-beam steel rod. The hole-position support rod 3 is connected to the two flange plates of the support rod 2 and can be fixed by welding, facilitating connection and fixation.

[0020] In this embodiment, the hole support rod 3 is a tubular structure with a hollow interior serving as an insertion hole for inserting the insertion connecting rod. Specifically, the hole support rod 3 can be made of steel, i.e., a steel pipe structure, providing the insertion position for the insertion connecting rod 4.

[0021] In this embodiment, the insertion connecting rod 4 can be a pin or a steel bar structure, or other structures, and no limitation is made in this embodiment.

[0022] In this embodiment, the steel pad base 1 serves as a platform. During manufacturing, the steel pad base 1 is welded and fixed to the support column 2. Then, the hole support rod 3 is welded and fixed to the support column 2 according to the designed rebar spacing. The insertion connecting rod 4 is a movable part that can be flexibly inserted into the insertion hole position as needed, providing a support surface for rebar binding. After the steel pad base 1 is arranged, the rebar binding can begin. The rebar can be placed directly on the platform with manual assistance, and binding and connection can be performed on the insertion connecting rod 4.

[0023] In summary, the rapid positioning and binding platform for precast rebar in large-scale tunnel jacking sections provided in this embodiment uses a steel base 1 for bottom support and support rods 2 for vertical support. The connecting rods 4 can be inserted into the support rods 3 via holes on the support rods 2, providing a support surface for rebar binding. This platform significantly improves the efficiency of rebar binding and the accuracy of rebar spacing control, solving the problems of low efficiency and large rebar spacing deviation in traditional rebar binding methods for large-scale tunnel jacking sections. Using this rapid positioning and binding platform allows for quick modular positioning of precast rebar, precise determination of rebar spacing, and preparation of rebar lap or mechanical connection joint positions according to specifications. This accelerates rebar binding and installation, reduces the number of workers, improves rebar binding quality, and significantly enhances the safety of rebar binding operations. This rebar binding platform has few accessories, a simple structure, and high practical value.
