The assembly plate and assembly bolts are used to facilitate the installation of the ring guide plate. The foundation pit support cylinder is lifted by a crane and placed into the ring guide plate. Finally, the support screw is installed and the adjusting nut and locking bolt are used to achieve the limit fixation.
[0016] (2) The present invention describes a guide auxiliary tool for the construction pit of overhead line cable-stayed power construction. Workers excavate the soil in the pit inside the pit support cylinder. After excavating to a certain depth, multiple construction workers simultaneously rotate the adjusting nut downwards to make the pit support cylinder sink. Then, they continue to excavate and support one section at a time until the pit design elevation is reached. This effectively provides support and prevents the pit from collapsing.

[0023] To facilitate rapid on-site assembly and easy disassembly and reuse of guide supports for overhead power line cable-stayed construction pits, an integral pit support cylinder is adopted. This design provides excellent protection against sidewall seepage and significantly improves safety. Figure 1-3 As shown, the present invention provides a guide tool for the construction pit of an overhead line cable-stayed structure for power construction, comprising a pit support cylinder 1, a positioning ring 7, an annular guide plate 9, and sheet piles 10. The bottom of the annular guide plate 9 is assembled with sheet piles 10 at equal intervals via assembly plates 13 and assembly bolts 14. Each sheet pile 10 has a triangular connecting block 8 welded to one side of its top end, and a sliding hole 16 is provided on one side of the bottom of the triangular connecting block 8. The pit support cylinder 1 is fitted inside the annular guide plate 9.
[0024] A positioning ring 7 is welded to the upper end of the foundation pit support cylinder 1. Horizontal positioning plates 2 are welded at equal intervals to the outer side of the positioning ring 7. A guide sleeve 4 is welded to the outermost end of the horizontal positioning plate 2 through a reserved hole. A support screw 3 is provided through the guide sleeve 4 and the sliding hole 16 at the bottom of the triangular connecting block 8.

[0034] When this utility model is used, after the location of the foundation pit is determined during the construction of the overhead line cable tie, multiple sheet piles 10 are driven into the soil in a circular pattern. The pile tip 11 is used to reduce the resistance to soil penetration and improve the sinking efficiency of the sheet piles 10. The assembly plate 13 and assembly bolts 14 are used to facilitate the installation of the annular guide plate 9.
[0035] Using a crane, the foundation pit support cylinder 1 is lifted and fitted into the annular guide plate 9. Finally, the support screw 3 is installed and fixed by adjusting nut 6 and locking bolt 15. Workers excavate the foundation pit soil inside the foundation pit support cylinder 1. After excavating to a certain depth, multiple workers simultaneously rotate the adjusting nut 6 downwards to make the foundation pit support cylinder 1 sink. Then, the excavation continues. One section is excavated and supported at a time until the design elevation of the foundation pit is reached, which effectively provides support and prevents the foundation pit from collapsing.
