Abstract
Description
Technical Field
[0001] This utility model relates to the field of measurement control point optimization technology, specifically, a convenient spiral anchor control pile and its preparation device. Background Technology
[0002] With the increasing workload of engineering projects, the large volume and weight of traditional surveying control piles have placed a significant burden on on-site surveyors in terms of transportation and burial. Therefore, we propose a spiral anchor control pile.
[0003] The prior art disclosed in CN 113982029 A, "Assembled and Combined Spiral Anchor Foundation and its Construction Method", describes a device that is widely used in the field of engineering design and construction. It is a new type of foundation, but it is used when it is inconvenient and control points cannot be measured. Utility Model Content
[0004] The purpose of this invention is to provide a convenient spiral anchor control pile and its preparation device, so as to reduce the transportation and burial pressure on on-site survey personnel, and to significantly reduce labor costs and material consumption.
[0005] To achieve the above objectives, the present invention employs the following technical means:
[0006] A convenient spiral anchor control pile includes an anchor rod, an anchoring screw blade coaxially mounted on a first side of the anchor rod along the axial direction, a positioning platform coaxially mounted on a second side of the anchor rod along the axial direction, and a positioning mark portion constructed on the side of the positioning platform relative to the anchoring screw blade.
[0007] Preferably, the positioning support includes a concrete block that is coupled to the anchor rod, and the outer wall of the concrete block is covered with a shaping tube, which is coaxially arranged with the anchor rod.
[0008] Furthermore, the diameter of the shaping tube is 5-10cm, and the height of the shaping tube is 5-10cm.
[0009] Furthermore, the bottom end of the positioning platform is located above the top end of the anchoring screw.
[0010] This application relates to a convenient spiral anchor control pile, which has the following beneficial effects during use:
[0011] The anchor rod is driven into the soil using a wrench or hand-held impact drill, burying the upper positioning platform. The protruding part of the anchor rod above the positioning platform serves as a positioning marker. Construction is fast and suitable for various soil conditions, performing particularly well in soft and sandy soil layers. Compared to traditional control piles, it significantly reduces labor costs and material consumption. The device itself is simple in structure, lightweight, and easy to construct, with advantages such as low on-site construction intensity and short time. It does not require large-scale excavation and does not affect the surrounding environment or vegetation. It is quick and lightweight. The diameter and length of the lower spiral anchor can be changed according to the hardness of the soil. It solves the problems of large size, heavy weight, and inconvenience of on-site excavation and burial associated with traditional control piles.
[0012] Furthermore, in order to manufacture the aforementioned convenient spiral anchor control pile, this application also relates to a preparation device, including a support plate with an annular groove, the support plate being horizontally arranged, the support plate having a positioning hole extending along the axis of the annular groove, the positioning hole being used to pass through the positioning mark portion, and the arcuate groove being used to coaxially embed the shaping tube.
[0013] Furthermore, the depth of the positioning hole is set to be the same as the length of the positioning mark portion.
[0014] Thus, with the preparation device involved in this application, when preparing the helical anchor control pile, the anchor rod can be inverted so that the positioning mark part of the anchor rod is inserted into the positioning hole. Then, the shaping tube is embedded into the annular groove, and concrete is poured into the shaping tube. After the concrete has solidified, the entire device can be removed. This not only ensures the coaxial arrangement of the shaping tube and the anchor rod, but also allows for the setting of helical anchor control piles with positioning mark parts of different lengths as needed, depending on the different depths of the positioning hole.

[0024] Please refer to Figure 1 and Figure 2 As shown, a convenient spiral anchor control pile includes an anchor rod 1, an anchoring screw 2 coaxially mounted on a first side of the anchor rod 1 along the axial direction, a positioning platform coaxially mounted on a second side of the anchor rod 1 along the axial direction, and a positioning mark portion constructed on the side of the anchor rod 1 relative to the anchoring screw 2 on the positioning platform.
[0025] In this way, the anchor rod 1 is screwed into the soil using a wrench or hand-held impact drill, burying the upper positioning platform, and the protruding part of the anchor rod 1, which is reserved above the positioning platform, serves as a positioning mark. Construction is fast and suitable for various soil conditions, performing particularly well in soft and sandy soil layers. Compared to traditional control piles, it significantly reduces labor costs and material consumption. The device itself is simple in structure, lightweight, and easy to construct, with advantages such as low on-site construction intensity and short time. It does not require large-scale excavation and does not affect the surrounding environment or vegetation. It is quick and lightweight. The diameter and length of the lower spiral anchor can be changed according to the hardness of the soil layer. It solves the problems of traditional control piles being large in size, heavy, and inconvenient for on-site excavation.
[0026] Furthermore, the positioning support includes a concrete block 3 that is coupled with the anchor rod 1, and the outer wall of the concrete block 3 is covered with a shaping tube 4, which is coaxially arranged with the anchor rod 1.
[0027] Furthermore, the diameter of the shaping tube 4 is 5-10cm, and the height of the shaping tube 4 is 5-10cm.
[0028] Specifically, the bottom end of the positioning platform is located above the top end of the anchoring screw 2.
[0029] In addition, a aforementioned convenient spiral anchor control pile preparation device includes a support plate 7 with an annular groove 6. The support plate 7 is horizontally arranged and has a positioning hole 8 that passes through the axis of the annular groove 6. The positioning hole 8 is used to pass through the positioning mark part 5, and the arc-shaped groove is used to coaxially embed the shaping tube 4.
[0030] Thus, for the preparation device involved in this application, when preparing the helical anchor control pile, the anchor rod 1 can be inverted so that the positioning mark part 5 of the anchor rod 1 is inserted into the positioning hole 8. Then, the shaping tube 4 is embedded into the annular groove 6, and concrete is poured into the shaping tube 4. After the concrete has solidified, the entire device can be removed. This not only ensures that the shaping tube 4 and the anchor rod 1 are coaxially arranged, but also allows for the setting of helical anchor control piles with different lengths of positioning mark parts 5 according to different depths of the positioning hole 8.
[0031] Furthermore, the depth of the positioning hole 8 is set to be the same as the length of the positioning mark part 5.
