Problems solved by technology

Since the foundation of the communication tower needs to be equipped with multiple oblique helical anchors, the cost is high and the construction period is long. Moreover, since the oblique helical anchors radiate from the center to the outer periphery of the vertical helical anchors, the damage to the lower appendages or vegetation is relatively large.

Embodiment 1

[0024] Such as Figure 1-Figure 3 As shown, a spiral cartridge type composite spiral anchor includes an anchor rod, a spiral anchor disc 1 and a spiral cartridge. The anchor rod comprises a guide anchor rod 7, and the spiral anchor disc 1 is arranged on the guide anchor rod 7, and the diameter of the guide anchor rod 7 is 219mm.

[0025] The spiral cartridge includes an upper spiral anchor plate 2 , a lower spiral anchor plate 3 and a cylinder body 4 . The upper spiral anchor disk 2 of the card cartridge and the lower spiral anchor disk 3 of the cartridge are fixed on the guide anchor rod 7 at intervals, the upper spiral anchor disk 2 of the card cartridge and the lower spiral anchor disk 3 of the card cartridge are coaxial with the guide anchor rod 7, The spiral anchor plate 2 on the cylinder is 1000mm away from the top end of the guide anchor rod 7 . The diameters of the spiral anchor disk 1, the upper spiral anchor disk 2 of the card cartridge and the lower spiral anchor ...

Embodiment 2

[0030] as shown in the picture Figure 4 As shown, different from Embodiment 1, the anchor rod of the spiral cartridge type composite helical anchor in this embodiment includes a guide anchor rod 7 and an extended anchor rod 8, and the spiral anchor disc 1 is arranged on the guide anchor rod 7, and the guide rod 7 is guided The anchor rod 7 is connected with the extension anchor rod 8 through a joint 9 . The spiral card cartridge is located on the extended anchor rod 8, and the spiral anchor plate 2 on the card cartridge is 1000mm from the top of the extended anchor rod 8.

[0031] Extending the anchor rod 8 is mainly used to lengthen the spiral anchor when the guide anchor rod 7 cannot meet the force requirements of the tower, so as to increase the buried depth of the spiral anchor sheet 1.

Embodiment 3

[0033]Different from Embodiment 2, the diameter of the bolt of the spiral cartridge type composite spiral anchor in this embodiment is 140mm, and the wall thickness is 13mm; the number of 2 spiral anchor plates is three, the diameter is 500mm, and the thickness is 16mm. The distance between the disks 2 is 1824mm; the diameter of the upper spiral anchor disk 2 of the cartridge and the lower spiral anchor disk of the cartridge is 500mm, the distance between the upper spiral anchor disk 2 of the cartridge and the top of the anchor rod is 1000mm, and the thickness is 16mm; the diameter of the cylinder 4 is 400mm, The wall thickness is 10mm and the length is 1000mm.

Abstract

The invention relates to the field of construction engineering, in particular to a spiral cartridge type composite spiral anchor, which includes an anchor rod, a spiral anchor disk and a spiral cartridge, the spiral anchor disk is coaxially fixed on the anchor rod, and the spiral cartridge It includes the upper spiral anchor plate of the card cartridge, the lower spiral anchor plate of the card cartridge and the cylinder body. The cylinder body is coaxially sleeved outside the anchor rod and its two ends are respectively fixed with the upper spiral anchor plate of the card cartridge and the lower spiral anchor plate of the card cartridge. connection, the upper spiral anchor plate of the cartridge is provided with a soil outlet, and the lower spiral anchor plate of the cartridge is provided with a soil inlet. The rotary cartridge type composite helical anchor of the present invention has a large bearing capacity of horizontal force, does not need secondary excavation, saves time and labor, has little disturbance to the soil, can fully utilize the strength of the soil structure, and has high economical efficiency.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a spiral cartridge type composite spiral anchor and a spiral cartridge. Background technique [0002] Spiral anchor foundations are used in construction engineering (such as steel structures, etc.), power engineering (substations, transmission lines, etc.), communication towers and other fields. [0003] In the engineering construction of high-voltage transmission lines, it is inevitable to pass through weak geological areas such as silt. In the past, the tower foundations in such areas mostly used large slab foundations, pile foundations, cast foundations or gravity foundations. It is safe, but the material consumption is large, the foundation pit is difficult to excavate, the investment is large, and the construction period is long. The advantages of simple manufacture, convenient installation and construction, short construction period, low cost, and little damage to t...
