Description

Technical Field

[0001] This utility model relates to the field of steel cage installation technology, specifically to a drilled cast-in-place pile with steel cage support and RTK positioning steel casing. Background Technology

[0002] In the construction of bored piles with mud wall protection, the lowering and extension of the reinforcing cage is a key link affecting the construction quality and safety.

[0003] Currently, the common practice on construction sites is to temporarily insert steel pipes into the gaps in the rebar cage and place them on the upper edge of the steel casing for temporary support. This method has significant drawbacks: the steel pipes are prone to slipping out of the gaps in the rebar cage, leading to the fall of the lowered rebar cage and posing a considerable safety hazard; at the same time, the steel pipes directly act on the stirrups of the rebar cage, easily causing deformation or damage to the stirrups and affecting the structural integrity; furthermore, traditional methods make it difficult to achieve precise positioning and elevation control of the steel casing, and as the rebar cage segments lengthen, its total weight increases, easily causing the steel casing to sink, further affecting the pile formation accuracy.

[0004] Based on this, this utility model proposes a drilled cast-in-place pile with a steel cage support and an RTK positioning steel casing. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model proposes a drilled cast-in-place pile with a reinforcing cage support and an RTK positioning steel casing. It can provide reliable and stable temporary support for the segmented lowering of the reinforcing cage by setting multiple synchronously controllable square steels integrated with the steel casing as a support mechanism, and combining them with limiting plates at both ends.

[0006] The technical solution to achieve the purpose of this utility model is: a steel casing for a bored pile with a steel cage support and RTK positioning, including a steel sleeve, a collar fixedly connected to the steel sleeve, a plurality of square steels slidably connected to the collar, a plurality of limiting plates fixedly connected to both ends of the plurality of square steels, and a plurality of RTK devices respectively provided at one end of the plurality of square steels near the inside of the steel sleeve.

[0007] Preferably, two handles are fixedly connected to the collar.

[0008] Preferably, a rotating ring is rotatably connected to the collar, and the rotating ring has multiple grooves.

[0009] Preferably, multiple connecting columns are fixedly connected to the multiple square steels, and the multiple connecting columns are respectively disposed in multiple grooves.

[0010] Preferably, a drive rod is fixedly connected to the rotating ring, and a handle is sleeved on the drive rod.

[0011] Compared with existing technologies, the significant advantages of this invention are:

[0012] Firstly, in this utility model, multiple square steels that can be synchronously controlled and integrated with the steel sleeve are set as a support mechanism, and combined with the limiting plates at both ends, a reliable and stable temporary support is provided for the segmented lowering of the steel cage. This fundamentally avoids the risk of the steel cage falling due to the easy slippage of the traditional temporary support steel pipe, and prevents structural damage to the stirrups of the steel cage.

[0013] Secondly, by integrating RTK equipment inside the square steel, the high-precision positioning and elevation measurement functions are combined with the steel cage support operation, realizing real-time and precise control of the steel casing positioning and elevation. This effectively solves the problems of poor positioning accuracy and easy sinking of the casing in traditional methods, and significantly improves the pile quality and construction efficiency.

[0019] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0020] This utility model provides an improved version of a drilled cast-in-place pile with a reinforcing cage support and an RTK positioning steel casing. The technical solution of this utility model is as follows:

[0021] like Figure 1 and Figure 2As shown, the bored pile with steel cage support and RTK positioning steel casing includes a steel sleeve 1, on which a collar 2 is welded. The collar 2 is made of thick steel plate with an outer diameter larger than that of the steel sleeve 1, forming an effective bearing surface. Multiple square steel bars 4 are slidably connected to the collar 2. The square steel bars 4 are arranged in a circular array with the center of the collar 2 as the center. Multiple limiting plates 5 are fixedly connected to both ends of the multiple square steel bars 4. The limiting plates 5 effectively prevent the square steel bars 4 from falling out of the collar 2 under stress. Multiple RTK devices 6 are respectively installed at the ends of the multiple square steel bars 4 near the inside of the steel sleeve 1. The RTK devices 6 are used to monitor the position and elevation of the casing in real time. By setting up multiple square steel bars 4 that can be synchronously controlled and integrated with the steel sleeve 1 as a support mechanism, and combined with the limiting plates 5 at both ends, reliable and stable temporary support is provided for the segmented lowering of the steel cage. This fundamentally avoids the risk of the steel cage falling due to the easy slippage of traditional temporary support steel pipes, and prevents structural damage to the stirrups of the steel cage.

[0022] Furthermore, such as Figure 1 As shown, two handles 3 are fixedly connected to the collar 2, which facilitates the handling and installation of the device.

[0023] Furthermore, such as Figure 1 and Figure 2 As shown, a rotating ring 7 is rotatably connected to the collar 2. The rotating ring 7 has multiple grooves 8, which are arranged in a circular array with the center of the rotating ring 7 as the center.

[0024] Furthermore, such as Figure 1 and Figure 2 As shown, multiple connecting columns 9 are fixedly connected to multiple square steels 4 respectively. The multiple connecting columns 9 are respectively set in multiple grooves 8. The positions of multiple square steels 4 are adjusted synchronously by using the grooves 8 and the connecting columns 9 in cooperation.

[0025] Furthermore, such as Figure 1 and Figure 2 As shown, a drive rod 10 is fixedly connected to the rotating ring 7, and a handle 11 is sleeved on the drive rod 10. The handle 11 is used to drive the drive rod 10 and the rotating ring 7 to rotate, so as to facilitate the adjustment of the position of the square steel 4.

[0026] The specific working method is as follows: First, the steel sleeve 1 is centered and placed at the predetermined opening position and pressed down to fix it, so that the bottom of the collar 2 contacts the soil surface to prevent the steel sleeve 1 from sliding down; then, mud wall drilling is carried out, and after cleaning the hole, the first section of the reinforcing cage is lowered to the elevation where the second section of the reinforcing cage can be welded; then, the handle 11 is rotated, which drives the drive rod 10 and the rotating ring 7 to rotate, and the groove 8 rotates accordingly. Since the connecting column 9 is located in the groove 8, the connecting column 9 moves with the rotation of the groove 8, which drives multiple square steels 4 to be inserted into the gap of the reinforcing cage into the steel sleeve 1. The two ends of the square steels 4 are welded with limiting plates 5 to prevent slippage. At the same time, the square steels 4 integrate RTK equipment 6 for real-time positioning and elevation determination; after the reinforcing cage is welded, the rotating ring 7 is rotated in the opposite direction, so that the square steels 4 are removed from the reinforcing cage, and the lowering of this section of the reinforcing cage is completed. The above steps are repeated until the lowering of the entire reinforcing cage is completed.

[0027] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
