Description

Technical Field

[0001] The utility model relates to the technical field of spiral anchor cap foundation, in particular to an assembled group-anchor spiral anchor cap foundation structure. Background Art

[0002] At present, the common foundation forms in power transmission lines include: step foundation, plate foundation, inclined foundation, rock foundation and pile foundation. Among them, step foundation, plate foundation and inclined foundation are also called "large excavation" foundation, which has large excavation volume, high cost and long construction period. Pile foundation consists of piles and caps, and piles can be cast-in-place piles, precast concrete piles, screw piles and other types.

[0003] Pile foundation has the advantages of high bearing capacity and strong adaptability, but pile foundation construction usually requires large machinery; for cast-in-place piles, the pile body must reach the designed bearing capacity before the cap can be cast, and the construction period is long. In addition, when drilling and piling the group-anchor spiral anchor pile foundation, the use of large machinery can easily cause the group spiral anchor to deviate to a certain extent, resulting in errors in the compressive bearing capacity and the tensile bearing capacity, and at the same time affect the pouring of the group-anchor spiral anchor pile foundation. The two are prone to incoordination when adapting to different upper load conditions. When the group-anchor spiral anchor pile foundation encounters changes in geological conditions or extreme climate events, uneven settlement occurs, resulting in instability of the cap foundation structure.

[0004] Therefore, in view of the shortcomings of the prior art, it is necessary to provide an assembled group anchor spiral anchor cap foundation structure to solve the shortcomings of the prior art. Utility Model Content

[0036] The utility model is further described in conjunction with the following embodiments.

[0037] Example 1.

[0038] like Figure 1-2 As shown, an assembled group-anchor spiral anchor cap foundation structure comprises a cap 1, which is arranged below the ground plane, an assembly mechanism 2 is installed on the cap 1, and fixing mechanisms 3 are arranged around the assembly mechanism 2.

[0039] The assembly mechanism 2 installed on the platform 1 can rotate the group of spiral anchors 9 to a position for rapid positioning, and the fixing mechanism 3 installed on the assembly mechanism 2 can rapidly position the assembly mechanism 2 on the platform 1 .

[0040] The assembly mechanism 2 includes an assembly base 4, which is arranged on the top of the base 1. Two groups of channels 5 are opened on the assembly base. An assembly sleeve 6 is installed inside the channel 5. The assembly sleeve 6 passes through the base 1. An anchor cable 7 is arranged inside the assembly sleeve 6. A connector 8 is connected below the anchor cable 7. A group of spiral anchors 9 is arranged below the connector 8.

[0041] The two groups of holes 5 in the assembly base 4 provided in the assembly mechanism 2 can limit the rotation position of the group spiral anchor 9, and the assembly sleeve 6 installed in the hole 5 can play a guiding role, which is convenient for the vertical drilling and installation of the group spiral anchor 9. The anchor cable 7 in the assembly sleeve 6 is connected to the connector 8 on the group spiral anchor 9. After installation, the platform 1 will be subjected to an upward pull force, which acts on the anchor cable 7 through the platform 1 and is transmitted to the group spiral anchor 9 through the anchor cable 7. The group spiral anchor 9 squeezes the soil above to generate an anti-pull force to offset this upward pull load.

[0042] The assembly sleeve 6 includes a cement molded part 10, and an auxiliary sleeve 11 is integrally formed at the bottom of the cement molded part 10. The auxiliary sleeve 11 passes through the base 1 and the assembly base 4. The assembly sleeve 6 connects the base 1 and the assembly base 4 to facilitate the drilling of the anchor cable 7 and the group spiral anchor 9. At the same time, the guiding function of the auxiliary sleeve 11 vertically guides the anchor cable 7 and the group spiral anchor 9 to ensure the accuracy of the drilling position.

[0043] The fixing mechanism 3 includes four groups of fixing rods 12, the top of the fixing rod 12 passes through the assembly base 4, the top of the fixing rod 12 is installed with a threaded rod 13, the threaded rod 13 is threaded with a large-sized nut 14, and the bottom of the fixing rod 12 is provided with a reverse tooth limit block 15.

[0044] The fixing rod 12 is nailed around the assembly base 4, and the top of the fixing rod 12 is quickly assembled through a threaded rod 13 and a large-size nut 14. At the same time, the bottom of the fixing rod 12 nailed into the ground can provide pull-out resistance through the inverted tooth limit block 15.

[0045] A toughened layer 16 is embedded inside the base 1, and a through hole 17 is provided on the toughened layer 16. The position of the through hole 17 corresponds to the assembly sleeve 6. The through hole 17 provided in the toughened layer 16 can play a limiting role, limiting the position of the group spiral anchor 9 to prevent deviation during the drilling process.

[0046] The bottom end of the anchor cable 7 is filled with a cement slurry layer 18 , and the bottom of the anchor cable 7 is detachably connected to the connector 8 . The cement slurry layer 18 can play a fixing effect and improve the stability of the bottom of the anchor cable 7 and the connector 8 .

[0047] During the production process, the group spiral anchor 9 is fixed in position by the assembly mechanism 2 installed on the pedestal 1, and the position of the group spiral anchor 9 is determined to prevent the spiral anchor body from shifting. The assembly base 4 in the assembly mechanism 2 is fixed to the ground by the detachable fixing mechanism 3. The assembly sleeve 6 arranged on the assembly base 4 fixes the drilling position of the group spiral anchor 9, and cooperates with the through hole 17 in the toughened layer 16 inside the pedestal 1 to prevent the shift from occurring. When subjected to the upward pull force, the upward pull force acts on the anchor cable 7 through the pedestal 1, and is transmitted to the group spiral anchor 9 through the anchor cable 7. The group spiral anchor 9 squeezes the soil above to generate a pull-out force to offset the upward pull load. The pull-out load generated by the inclination of the tall structure is also balanced by the pull-out bearing capacity of the group spiral anchor 9 to achieve the purpose of stability.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
