Description

Technical Field

[0001] This utility model relates to the field of rotary drilling technology in Gobi Desert terrain, and in particular to a protective pile structure for rotary drilling in Gobi Desert terrain. Background Technology

[0002] The Gobi Desert, as a unique geological environment, is typically characterized by its flat and open terrain, lack of surface water, and predominantly gravelly soil. Constructing pile foundations, especially rotary drilling rigs, in this environment presents a series of unique challenges. Rotary drilling rigs are an advanced pile foundation construction technology, characterized by rapid drilling speed, high pile quality, and short construction period. However, the application of rotary drilling rig technology in the Gobi Desert requires special consideration of geological and climatic factors.

[0003] A rotary drilling cast-in-place pile structure, disclosed in publication number CN215518729U, includes a reinforcing cage located inside the pile hole. A positioning frame is fitted onto the bottom of the reinforcing cage and is located at the bottom of the pile hole. The positioning frame includes several positioning rings and positioning rods. The positioning rings are fitted onto the reinforcing cage and connected by positioning rods. The axis of the positioning rings coincides with the axis of the pile hole. This application effectively improves the defect where the axis of the reinforcing cage is difficult to coincide with the axis of the pile hole, leading to a reduction in the bearing capacity of the cast-in-place pile.

[0004] Rotary drilling cast-in-place piles are a common foundation treatment method, and the reinforcing cage in their structure plays a crucial role. It is mainly used to enhance the bearing capacity of the pile, prevent the pile from deforming under stress, and ensure the stability of the building. However, the reinforcing cage inside the existing cast-in-place piles is inconvenient to assemble longitudinally, which may lead to weak longitudinal connections of the reinforcing cage, thereby affecting the overall bearing capacity of the pile. Under long-term load, the pile may develop cracks or deformation, or even fail. The inconvenience of longitudinal assembly of the reinforcing cage increases the construction difficulty and time cost. Construction personnel may need to spend more time and effort to ensure the assembly quality and accuracy. Therefore, corresponding improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to provide a rotary drilling and protection pile structure for Gobi desert terrain, so as to solve the problem mentioned in the background art that the existing rotary drilling and protection pile structure for Gobi desert terrain is inconvenient to longitudinally splice the protection piles and has limited use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotary drilling and pile protection structure for Gobi landforms, comprising a Gobi soil layer and pile holes, wherein the pile holes are provided inside the Gobi soil layer;

[0007] A steel cage assembly is installed inside the Gobi soil layer. The bottom of the steel cage assembly is connected to a supporting base, and sliding mechanisms are provided on both sides of the supporting base.

[0008] Preferably, the steel cage assembly includes a connecting plate and a bottom support, with supporting steel columns evenly fixed between the connecting plate and the bottom support. Multiple outer stirrups are evenly welded to the outside of the supporting steel columns, and reinforcing columns are evenly fixed between the outer stirrups.

[0009] Preferably, seven supporting ribs are provided between the connecting plate and the base, and the seven supporting ribs are arranged in a ring on the connecting plate and the base.

[0010] Preferably, the outer stirrups are distributed at equal intervals around the periphery of the supporting column, and the reinforcing column is distributed in a ring shape on the outer stirrups.

[0011] Preferably, a docking component is provided between the connecting plate and the base, and two sets of docking components are provided. The docking component includes a slot and a docking block. The slot is provided on the base, and the docking block is fixed to the bottom end of the connecting plate. The slot and the docking block are positioned correspondingly.

[0012] Preferably, hook blocks are provided on both sides of the slot, and locking blocks are provided between the hook blocks. The locking blocks are fixed to the bottom of the docking block, and the locking blocks and hook blocks are engaged with each other.

[0013] Preferably, the sliding mechanism includes a built-in groove, which is formed on the supporting chassis. A return spring is connected inside the built-in groove, and a connecting plate is fixed to one end of the return spring. A pusher is connected to one side of the connecting plate, and a roller is connected to one side of the pusher. The roller contacts the inner wall of the pile hole. Guide posts are passed through both sides of the inside of the connecting plate, and the guide posts are set inside the built-in groove.

[0014] Preferably, the concrete injected into the pile hole, together with the steel cage assembly, forms a rotary drilling pile protection structure.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the rotary drilling pile structure for Gobi landforms has high strength, the internally supported steel cage can be easily assembled to meet different usage requirements, and it has an internal positioning effect, as well as the effect of the steel cage smoothly entering the borehole, and correspondingly preventing the steel cage from shifting.

[0016] According to the depth of the pile hole, the connecting block and the locking block are inserted into the corresponding slot. By using the interlocking of the locking block and the hook block, the connecting plate and the bottom support can be easily assembled to extend the length of the steel cage. As the main load-bearing component inside the rotary drilling and grouting pile, the steel cage can significantly improve the bearing capacity of the pile. It can be extended longitudinally to adapt to pile foundations of different depths, enhance the bearing capacity of the pile, adapt to the special geological conditions of the Gobi landform, and accelerate the infrastructure construction in the Gobi region.

[0017] The rollers roll on the inner wall of the pile hole, changing the contact between the reinforcing cage and the inner wall of the pile hole from friction to rolling during the placement process. This reduces frictional resistance, which helps the reinforcing cage to enter the pile hole more smoothly and quickly, improving construction efficiency. The rollers utilize the extensibility of the return spring to meet the needs of pile holes of different diameters and prevent the reinforcing cage from shifting position in the pile hole, thereby enhancing the structural strength of the rotary drilling pile protection.

[0029] The outer stirrups 5 are distributed at equal intervals around the outer perimeter of the supporting column 4, and the reinforcing column 501 is distributed in a ring shape on the outer stirrups 5;

[0030] Please refer to the details. Figure 1 , Figure 2 A steel cage assembly is inserted into the pile hole 2, and concrete is injected into the pile hole 2 to form a rotary drilling protective pile. The steel cage assembly can enhance the bearing capacity and improve the stability of the protective pile. The steel cage assembly includes multiple supporting columns 4 and multiple outer stirrups 5, forming the internal support of the rotary drilling protective pile. The multiple outer stirrups 5 are further supported and connected by reinforcing columns 501, which can further enhance the bearing capacity of the steel cage and make it stronger.

[0031] Seven support ribs 4 are provided between the connecting plate 7 and the base 8, and the seven support ribs 4 are distributed in a ring on the connecting plate 7 and the base 8.

[0032] Please refer to the details. Figure 1 , Figure 2 The arrangement of multiple ring-shaped connecting discs 7 ensures uniform support force and better support effect.

[0033] A docking assembly is provided between the connecting plate 7 and the base 8, and there are two sets of docking assemblies. The docking assembly includes a slot 801 and a docking block 701. The slot 801 is set on the base 8, and the docking block 701 is fixed to the bottom end of the connecting plate 7. The slot 801 and the docking block 701 are positioned correspondingly.

[0034] Please refer to the details. Figure 2 , Figure 4 , Figure 5 Insert the connecting block 701 and the locking block 702 into the corresponding slot 801. By using the interlocking of the locking block 702 and the hook block 802, the connecting plate 7 and the base support 8 can be easily assembled to extend the length of the steel cage bus, so as to adapt to pile foundations of different depths, enhance the bearing capacity of the pile, and adapt to the special geological conditions of the Gobi Desert.

[0035] Example 2

[0036] This embodiment differs from Embodiment 1. By utilizing the sliding mechanism 6, the rebar cage can be conveniently and efficiently deployed, thereby improving the forming efficiency of rotary drilling pile protection. Therefore, the following technical solution is disclosed: The bottom of the rebar cage assembly is connected to a bearing base 3, and a sliding mechanism 6 is provided on both sides of the bearing base 3. The sliding mechanism 6 includes an internal groove 601, which is opened on the bearing base 3.

After entering pile hole 2, the rollers 605 will roll on the inner wall of pile hole 2, so that the contact between the steel cage and the inner wall of pile hole 2 during the placement process changes from friction to rolling, reducing resistance. This helps the steel cage to enter the pile hole 2 more smoothly and quickly, improving construction efficiency. The retractable performance of the return spring 602 can make the rollers 605 adapt to the use of pile holes 2 of different specifications. Moreover, the rollers 605 on both sides of the bearing base 3 are in contact with the inner wall of pile hole 2, so the steel cage is not easy to deviate or tilt. This helps to ensure the verticality and bearing capacity of the pile foundation, and improves construction quality and safety.
