Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a precise positioning device for pre-buried steel pipes of anchor piles. Background Art

[0002] Anchor piles are a type of anti-slide pile. They reinforce soil or rock by tightening the steel bars in reinforced concrete piles. Their use requires that the reinforced concrete piles are already anchored underground. The application of tension improves the stability of the soil or rock mass. Anchor piles can be designed based on site needs and are commonly used to stabilize building foundations and reinforce rock slopes.

[0003] In existing technologies, the anchor cable of an anchor pile must be inserted from the top beam of the pile body, through the window, and into the slope. During this insertion process, the anchor cable can easily come into contact with the existing steel bars in the anchor pile, damaging them during the insertion process and thus weakening the anchor pile's function.

[0004] Therefore, pre-buried steel pipes also play an important role in anchor pile construction. They serve as a reserve for the anchor rod holes, providing accurate positioning and guidance for subsequent anchor rod installation. This prevents the anchor cable from damaging the anchor pile during the implantation process. Utility Model Content

[0005] The purpose of the utility model is to provide a precise positioning device for pre-buried steel pipes of anchor piles, which can effectively improve the accuracy during the implantation of anchor cables, penetrate the anchor cables into the predetermined positions, and protect the anchor piles from being damaged.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows:

[0007] A precise positioning device for embedded steel pipes of anchor piles, comprising an anchor pile, wherein the anchor pile comprises an buried section and an exposed section, and further comprises a steel pipe assembly embedded in the exposed section, and a plugging mechanism connected to both ends of the steel pipe assembly; the steel pipe assembly comprises a hollow outer steel pipe, an inner support steel pipe arranged within the outer steel pipe, the inner support steel pipe being a solid piece, and one end of the inner support steel pipe passing through the plugging mechanism; a clamping groove is provided on the outer side of the outer steel pipe, and the clamping groove is clamped on the steel bar of the anchor pile.

[0008] Furthermore, the end surface of the outer steel pipe is provided with a plurality of locking holes.

[0009] Furthermore, the locking hole is connected to the outermost side of the clamping groove, and a locking screw is connected in the locking hole.

[0010] Furthermore, the plurality of locking holes are evenly spaced along the arc-shaped surface of the outer steel pipe.

[0011] Furthermore, the plugging mechanism includes a first plug and a second plug respectively connected to the two ends of the external steel pipe, and a connecting thread adapted to the plugging mechanism is provided in the external steel pipe.

[0012] Furthermore, a through hole adapted to the inner supporting steel pipe is provided in the middle of the first plug.

[0013] Compared with the existing technology, the advantages of the present invention are: First, the present invention adopts a steel pipe assembly arranged at the exposed section of the anchor pile. By pre-embedding the steel pipe assembly and connecting it to the anchor pile before pouring, a reserved passage can be provided for the anchor cable after pouring, and the steel bars of the anchor pile will not be damaged when the anchor cable is inserted.

[0014] Secondly, the steel pipe assembly used in this invention has a double-layer structure, and the inner supporting steel pipe can provide good internal support for the outer steel pipe, preventing the outer steel pipe from deforming during the pouring process. The outer steel pipe is connected to the steel bar of the anchor pile through a locking screw and a clamping groove, which makes the position of the steel pipe less prone to deviation and achieves a good positioning effect.

[0025] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0026] like Figure 1-Figure 2 As shown, a precise positioning device for embedded steel pipes of anchor piles includes an anchor pile, and the anchor pile includes an buried section 3 and an exposed section 4, and also includes a steel pipe assembly embedded in the exposed section 4, and a plugging mechanism connected to both ends of the steel pipe assembly; the steel pipe assembly includes a hollow external steel pipe 5, an internal support steel pipe 6 arranged in the external steel pipe 5, the internal support steel pipe 6 is a solid piece, and one end of the internal support steel pipe 6 passes through the plugging mechanism; a clamping groove 7 is provided on the outside of the external steel pipe 5, and the clamping groove 7 is clamped on the steel bar of the anchor pile.

[0027] Compared with the prior art, in the prior art, the embedded steel pipe also plays an important role. It can be used as a reserve for the anchor rod channel, providing accurate positioning and guidance for the later installation of the anchor rod. Specifically, the production and installation of the embedded steel pipe need to follow certain process requirements. The main problem with the embedded steel pipe method is that the position of the embedded steel pipe may be offset when the anchor pile is cast, which causes the position of the anchor cable 2 to be offset when the anchor cable 2 is passed in the later stage, which is inconsistent with the designed position. In the present utility model, the embedded steel pipe is set as a steel pipe assembly, and the steel pipe assembly includes an external steel pipe 5 and an internal support steel pipe 6. On the one hand, the internal support steel pipe 6 is a solid piece that can play the role of internal support for the external steel pipe 5 during casting, avoiding deformation of the external steel pipe 5 during the casting process. When the anchor cable 2 is passed through in the later stage, the internal support steel pipe 6 can be taken out, and the overall structure is simple. At the same time, a clamping groove 7 is provided on the external steel pipe 5, and the clamping groove 7 is used to fix the steel pipe assembly, so that the subsequent anchor cable 2 can provide more accurate positioning.

[0028] The end surface of the outer steel tube 5 is provided with a plurality of locking holes 8. The locking holes 8 are connected to the outermost side of the clamping groove 7, and a locking screw is connected in the locking hole 8. The plurality of locking holes 8 are evenly spaced along the curved surface of the outer steel tube 5.

[0029] The plugging mechanism includes a first plug and a second plug connected to both ends of the external steel pipe 5, and a connecting thread adapted to the plugging mechanism is provided in the external steel pipe 5. A through hole adapted to the inner support steel pipe 6 is provided in the middle of the first plug.

[0030] In actual use, anchor piles are constructed using C30 concrete, with a steel reinforcement layer thickness of no less than 7 cm. Pile wells should be excavated in sections, with each pile separated. Mechanical drilling or rotary drilling is recommended for the pile bodies. During excavation, detailed records of stratum lithology, water content, and contact surfaces must be kept. Any discrepancies with geological data should be promptly notified to the survey and design firm and other relevant parties.

[0031] Cast-in-place concrete retaining plates are installed between the exposed sections of the pile body. The required strength is no less than C30, and the plates are 40cm thick. Drain holes are reserved within the plates. The retaining plate's reinforcement is anchored within the anti-slip pile concrete using embedded reinforcement technology. Construction of the crown beam 1 and retaining plates can only begin after the pile construction is completed and qualified. The precise positioning device provided by the utility model is embedded within the crown beam 1 during its construction. A Φ146 steel pipe is embedded before the crown beam 1 is cast, and both ends of the steel pipe must be sealed. The incident angle of the anchor cable 2 is set at 15 to 30 degrees, depending on the specific situation.

[0032] When pre-embedding the steel pipe assembly, the outer steel pipe 5 is fitted over the reinforcement of the crown beam 1 using the snap-fit ​​groove 7, and the locking screw is inserted into the locking hole 8 to secure the outer steel pipe 5 relative to the crown beam 1. After the crown beam 1 is cast, the inner support steel pipe 6 and the plugging mechanism are removed to reserve a passage for the anchor cable 2.

[0033] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
