Description

Technical Field

[0001] This invention belongs to the field of pile foundation construction, and in particular relates to an adjustable conical pile hole protection device and its usage method. Background Technology

[0002] During the pile foundation construction phase of building engineering, pile holes exist on the site for a long time, and their dense locations and unclear patterns often bring various hidden dangers, such as safety risks like workers falling and increased cleaning work due to falling debris. Therefore, pile hole safety protection has become a key and difficult issue in construction site safety management. Existing technologies often use measures such as setting up guardrails near the pile holes and installing protective covers or nets at the pile holes. However, guardrails require a large investment of manpower and materials, and their construction and dismantling are slow and occupy a large amount of site space; covers or nets are prone to displacement and cannot be used interchangeably for pile holes of different diameters, resulting in material waste and other technical problems. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides an adjustable conical pile hole protection device and its usage method, which is particularly suitable for pile hole protection of various diameters. It has a simple structure, quick installation, low cost, and good application prospects.

[0004] The technical solution adopted in this invention is: an adjustable conical pile hole protection device, including a protective disc, a conical protective frame body provided on the upper part of the protective disc, a telescopic track provided on the lower part of the protective disc, a steel plate strip provided in the telescopic track, the steel plate strip being able to slide within the telescopic track; an adjustment mechanism provided on the lower part of the protective disc, the adjustment mechanism being connected to the steel plate strip, allowing the steel plate strip to move; the area of ​​the protective disc and the telescopic track is larger than the area of ​​the pile hole, located above the pile hole, and the steel plate strip extending into the pile hole and clamping against the side wall of the pile hole.

[0005] Furthermore, the conical protective frame includes a triangular support, reinforcing bars, and a safety warning steel strip; the reinforcing bars are connected to the side frame of the triangular support; and the safety warning steel strip is installed on the triangular support.

[0006] Furthermore, the telescopic track is planar spiral, and the steel strip has holes.

[0007] Furthermore, the adjustment mechanism includes an adjustment buckle, a rotating spindle, a rotating screw, and a flange; the adjustment buckle is located in the middle of the protective disc, locking one end of the rotating spindle so that the rotating spindle can rotate around its axis; the adjustment buckle is provided with a limit device; the flange is provided at the other end of the rotating spindle; the rotating screw is vertically fixed to the middle of the rotating spindle, and the end of the rotating screw can extend into the hole of the steel strip.

[0008] Furthermore, the rotating screws are two or more.

[0009] Furthermore, the protective disc is provided with an observation hole, which is located in the gap of the telescopic track.

[0010] Furthermore, a column is provided on the upper part of the protective disc, and the top of the column is connected to the top of the conical protective frame; an insertion hole is provided on the top of the column, and a warning flag is placed in the insertion hole, with the warning flag extending out of the conical protective frame.

[0011] The present invention also provides a method for using an adjustable conical pile hole protection device, comprising the following steps:

[0012] S1. Measure the diameter of the pile hole;

[0013] S2. Rotate the flange to make the mandrel rotate, which in turn drives the rotating screw to rotate, thereby driving the steel strip to move around the rotating mandrel along the telescopic track, achieving the effect of contraction or expansion, so that the area enclosed by the steel strip is slightly smaller than the area of ​​the pile hole, and the limiting device is locked.

[0014] S3. Install the pile hole protection device at the pile hole;

[0015] S4. Observe the pile hole and the steel plate strip through the observation hole. If any changes occur, they can be dealt with in a timely manner.

[0016] S5. When construction is required at the pile hole, the pile hole protection device is removed and moved to the next pile hole, repeating S1-S4.

[0017] The advantages and positive effects of this invention are as follows: Due to the adoption of the above technical solution, the area of ​​the steel plate strip extending into the pile hole can be adjusted, which is convenient and has a wide range of area variation, thus adapting to pile holes of different diameters, facilitating reuse, and saving material costs; the conical protective frame is located above the pile hole, with clear markings and easy identification, and its lower part extends into the pile hole, making it less prone to displacement, occupying a small area, and providing higher safety; at the same time, it is simple to manufacture, quick to install, and has a lower cost, making it highly practical.

[0025] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0026] like Figure 1-2 As shown, in one embodiment of the present invention, an adjustable conical pile hole protection device includes a protective disc 1. A conical protective frame 2 is welded above the protective disc 1. A telescopic track 3 is fixed below the protective disc 1. The area of ​​the telescopic track 3 is larger than the area of ​​the pile hole 11, allowing the telescopic track 3, the protective disc 1, and the conical protective frame 2 to protrude from the ground for easy identification, while occupying little space and reducing encroachment on the construction work surface. A steel plate strip 4 is provided inside the telescopic track 3. The steel plate strip 4 can slide flexibly within the telescopic track and extend into the pile hole 11, locking it tightly to prevent the entire structure from moving easily. An adjustment mechanism 5 is provided at the lower part of the protective disc 1. The adjustment mechanism 5 is connected to the steel plate strip 4, allowing the steel plate strip 4 to move, thereby increasing or decreasing the area enclosed by the entire steel plate strip. This allows the device to be applied to pile holes of different diameters.

[0027] like Figure 2 , 3 As shown, in a specific embodiment, the conical protective frame 2 includes a triangular support 21, reinforcing steel bars 22, and a safety warning steel strip 23; the triangular support 21 is welded together from 6 rod-like structures and is integrally welded to the top of the protective disc 1; there is one or more reinforcing steel bars 22, which are welded to the side frame of the triangular support 21; at the same time, a safety warning steel strip 23 is provided on the triangular support 21, and the surface is coated with safety warning paint, which makes it easier to identify and improves the safety of the protective device.

[0028] like Figure 4-5As shown, in one specific embodiment, the telescopic track 3 is configured as a planar spiral, and the steel strip has holes. In a preferred embodiment, the adjustment mechanism 5 includes an adjustment buckle 51, a rotating spindle 52, a rotating screw 53, and a flange 54. The adjustment buckle 51 is located in the middle of the protective disc, which is also the center of the planar spiral telescopic track 3. One end of the rotating spindle 52 is engaged with the adjustment buckle 51, and the other end is fixed to the flange 54. The rotating spindle 52 can rotate around its axis. The adjustment buckle 51 is provided with a limit device, which can restrict the rotation of the rotating spindle 52 after being engaged. The rotating screw 53 is located in the middle of the rotating spindle, perpendicular to the rotating spindle 52, and can be composed of one or more screws. The end of the rotating screw 53 can extend into the holes of the steel strip 4.

[0029] In one specific embodiment, the protective disc 1 is provided with an observation hole 6 located in the gap of the telescopic track 31. Multiple observation holes 6 can be provided. Through the observation hole 6, the inside of the pile hole 11 and the condition of the steel plate strip 4 can be seen.

[0030] In one specific embodiment, a column 7 is provided on the upper part of the protective disc 1. The top of the column 7 is connected to the top of the conical protective frame 2. The top of the column 7 is provided with an insertion hole, and a warning flag 8 is placed in the insertion hole. The warning flag extends out of the conical protective frame 2, and the construction personnel can see the protective device from a distance, which further improves safety.

[0031] In one specific embodiment, the following method of use is adopted: First, according to the diameter of the pile hole, rotate the flange 54 to make the rotating mandrel 52 rotate, which drives the rotating screw 53 to rotate. Since the screw end of the rotating screw 53 extends into the hole in the steel plate strip 4, it can drive the steel plate strip 4 to move around the rotating mandrel 52 along the telescopic track 3, so as to achieve the effect of contraction or expansion, making the area enclosed by the steel plate strip 4 slightly smaller than the area of ​​the pile hole 11. After fixing the rotating mandrel 52 by adjusting the limiting device of the buckle 51, the device can be installed at the pile hole. During use, the pile hole 11 and the steel plate strip 4 can be observed at any time through the observation hole. If any changes occur, they can be dealt with in time. When the pile hole 11 needs to be constructed, the device can be moved out and reused at the next pile hole 11 after adjustment.

[0032] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
