Description

Technical Field

[0001] The utility model relates to the technical field of cable docking, in particular to a quick-installable electric pole foundation. Background Art

[0002] Utility poles are commonly used for overhead lines in distribution networks and are a crucial component of transmission lines. Traditionally, the foundation construction of distribution network towers involves multiple steps, including on-site concrete formwork, formulation, mixing, pouring, and curing. However, these processes present challenges such as long construction cycles, significant impact on the construction team's technical proficiency, and significant environmental damage on the worksite.

[0003] The patent publication number is CN219691222U, a Chinese utility model patent published on September 15, 2023, which discloses a structurally stable cement pole foundation. It is equipped with positioning installation components, protective components and auxiliary components. When in use, the pole is inserted into the through hole on the upper end face of the base, and then the screw drives the A threaded ring and the B threaded ring to move. Then the A threaded ring and the B threaded ring drive the four positioning rods to be inserted into the corresponding positioning holes respectively, thereby strengthening the connectivity between the pole and the base. Then the two guard plates wrap the pole and then fix it with a locking bolt. Then the cross bar is pulled out of the sleeve rod, and then the cross bar drives the arc plate to support the protective tube, thereby supporting the protective tube and the pole, thereby reducing the risk of the pole tilting after a long time. However, its protective components and other parts are an integrated structure with a large volume, which is not convenient for transportation and installation. Utility Model Content

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] like Figure 1-Figure 5 As shown, the quick-installed pole foundation of this embodiment includes a fixing cylinder 1. Multiple fixing cylinders 1 are longitudinally connected to form the pole foundation. The fixing cylinder 1 includes two semi-cylinders, and the two semi-cylinders are connected using a connecting device 2. The connecting device 2 includes a locking groove 21, a locking block 22, a locking head 23 and a screw 24. The locking groove 21 is fixed to one half of the cylinder, one end of the locking block 22 is fixed to the other half of the cylinder, and the other end of the locking block 22 is clamped with the locking groove 21; the bottom ends of the two screws 24 respectively pass through the two ends of the locking block 22 and then extend to the bottom of the pole foundation. Both ends of the screw 24 are threadedly connected with a nut 25, and the outer periphery of the nut 25 is threadedly connected with a locking head 23.

[0027] When installing the fixing tube 1, the fixing tubes 1 of each layer are assembled in sequence from bottom to top: the fixing tubes 1 at the bottom layer are spliced ​​first. The pole foundation of the present invention can be prefabricated in advance and directly installed on site, which greatly reduces the difficulty of the construction process and avoids the problem of uneven construction quality caused by different workmanship levels. The pole can meet the needs of pole operations after the pole is inserted, saving a lot of time consumed by waiting for the poured concrete mortar to dry before performing pole operations in the "wet operation" mode, significantly shortening the construction period of the distribution network pole, and meeting the needs of emergency operations with tight cycles such as rapid repairs and construction. It can be used in distribution network repair operations under disaster conditions, effectively improving the repair efficiency and disaster resistance of power grid disasters.

[0028] Furthermore, the fixed cylinder 1 includes an inner cylinder 11 and an outer cylinder 12. A plurality of support rods 15 are fixed at even intervals on the outer circumference of the inner cylinder 11. The reinforcement block 13 is detachably connected to the support rod 15. One end of the reinforcement block 13 abuts against the outer wall of the inner cylinder 11, and the other end of the reinforcement block 13 abuts against the inner wall of the outer cylinder 12. A cavity 17 is formed between adjacent reinforcement blocks 13.

[0029] The reinforcement block 13 ensures that the pole foundation can withstand the lateral tilting moment of the pole without deformation after the pole foundation is buried in the underground foundation pit, providing a structural guarantee for workers to work on the pole; the remaining space in the cavity 17 is used to fill with concrete mortar or a filler with a strength not less than the strength of the concrete mortar after drying, and the outer side of the outer tube 12 is used to abut against the underground soil where the pole is installed

[0030] Furthermore, a plurality of positioning baffles 14 are fixed to the inner wall of the outer cylinder 12 at even intervals.

[0031] The positioning baffle 14 plays a role of radial positioning, facilitating the stacking of the fixed cylinders 1 in adjacent layers.

[0032] Furthermore, a first reinforcing rib 16 is fixed between the inner tube 11 and the outer tube 12 .

[0033] Furthermore, the connecting rod 19 longitudinally penetrates the plurality of reinforcing blocks 13 and is fixed to the reinforcing blocks 13 .

[0034] Furthermore, a second reinforcing rib 26 is fixed to the outer periphery of the locking groove 21 and the outer periphery of the locking block 22 . One end of the second reinforcing rib 26 is fixed to the outer wall of the inner tube 11 , and the other end of the second reinforcing rib 26 is fixed to the inner wall of the outer tube 12 .

[0035] Furthermore, the fastening nail 27 passes through the second reinforcing rib 26 , the locking block 22 and the locking head 23 in sequence and then abuts against the screw rod 24 .

[0036] The fastening nail 27 abuts against the screw 24 to prevent the screw 24 from loosening and ensure the stability of the connection between the upper and lower fixed cylinders 1

[0037] Furthermore, reinforcement rings 18 are fixed at both ends of the pole foundation.

[0038] The method of using the utility model is as follows:

[0039] (1) Dig the foundation pit and clean and level the bottom;

[0040] (2) Place the stopper device flat on the bottom of the foundation pit;

[0041] (3) above the stopper, the two semi-circular cylinders of the first layer of fixed cylinders 1 are aligned and connected, and the fixed cylinders 1 of each layer are stacked and connected, completing the alignment connection of each layer of fixed cylinders 1 and the stacking connection of the fixed cylinders 1 of the upper and lower adjacent layers in sequence from bottom to top;

[0042] (4) Backfill the space between the outer tube 12 of the fixed tube 1 and the side wall of the foundation pit;

[0043] (5) Insert the electric pole into the inner tube 11 and fill the remaining space inside the inner tube 11 with soil;

[0044] (6) After the construction workers have completed the work on the pole, they pour filler into the cavity 17.

[0045] It should be noted that the tower foundation of the straight pole of the 10kV overhead line project needs to be reinforced to meet the design requirements of high wind speed. The construction period of the distribution network tower foundation using the traditional on-site casting method usually takes 7 days, and it takes nearly 7 days to wait for the foundation concrete strength to approach 100%, resulting in a total waiting time of 14 days for the line construction. However, after testing, the method of the present invention takes 3 hours from the excavation of the foundation pit in step (1) to the completion of the compaction and embedding of the foundation in step (5), which can reduce the construction period to 3 hours, and has a significant construction period advantage.

[0046] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
