Description

Technical Field

[0001] This utility model relates to a force loading device for a static penetrometer, and more particularly to a force loading device for a static penetrometer applied in the field of force equipment technology. Background Technology

[0002] A static cone penetrometer (PCP) is a commonly used geological information acquisition instrument. Its main uses include: determining vertical and horizontal variations in strata; performing mechanical stratification; determining the bearing capacity of natural foundations and estimating the bearing capacity of single piles; assessing the likelihood of soil liquefaction; determining the undrained shear strength of soft soil; and providing calculation indicators for the bearing capacity of soft soil foundations and slope stability. PCPs are suitable for in-situ testing of foundation soils in civil engineering, municipal engineering, highway construction, and other projects in areas with general cohesive soils, soft soils, loess, and dense sandy soils. Their applications are extremely wide. When using a PCP for geological information acquisition, stable support is required to facilitate the application of pressure to the ground.

[0003] To address the issue of static cone penetrometers exerting pressure on the ground, a certain static cone penetrometer on the market employs a loading device design, which has a certain market share.

[0004] Currently, the force loading devices commonly used in the market for static cone penetrometers are generally just two iron plates, with a small contact area with the ground and poor stability. Once strong winds occur, the static cone penetrometer is prone to tipping over. Utility Model Content

[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that the static penetrometer force loading device has a small contact area with the ground and poor stability. Once strong winds occur, the static penetrometer is prone to tipping over.

[0006] To address the aforementioned problems, this utility model provides a static penetrometer force loading device, comprising a static penetrometer force body with a base at the bottom, a plurality of first slots equally spaced at the top of the base, a pressure-applying gravity bar detachably connected to the first slot, symmetrical perforations symmetrically carved at the top of the base near the static penetrometer force body, a positioning stake rotatably connected within the perforations, a stake head fixedly connected to the top of the positioning stake, a groove carved at the top of the stake head, a first buckle fixedly connected to the top of the pressure-applying gravity bar located directly above the first slot, and second buckles symmetrically fixedly connected to the side end of the static penetrometer force body, with the second buckles connected to the first buckles via a pull rope.

[0007] In the above-mentioned static cone penetrometer force loading device, the strong loading device is effectively fixed to the ground, thereby improving the lateral stability of the static cone penetrometer force and its wind resistance performance.

[0008] As a further improvement of this application, hooks are fixedly connected to both ends of the pull rope, and the hooks are engaged with the second buckle and the first buckle respectively.

[0009] As a further improvement to this application, the pressure gravity bar is designed with various weight specifications, and the pull rope is designed to be non-elastic.

[0010] As a further improvement of this application, the groove engages with the perforation.

[0011] As another improvement of this application, an electric drill with a drill bit is detachably connected to the groove, and the drill bit engages with the groove.

[0012] As a further improvement to this application, a second slot corresponding to the first slot is chiseled at the bottom end of the pressure gravity bar, and the second slot engages with the first slot.

[0013] In summary, this solution enables the following: When using a static cone penetrometer (PCP) for geological information collection, the PCP needs to be fixed to the ground using a loading device. The PCP can be placed horizontally, and the pressure bar is engaged in the first slot, bringing it into contact with the ground to test the pressure on the base and prevent the PCP from shaking. Then, a positioning stake is inserted into the hole. By inserting a drill bit into the groove and starting the drill, the positioning stake rotates and drills a hole in the ground, ensuring it is firmly fixed to the ground. This effectively secures the loading device to the ground, improving the lateral stability and wind resistance of the PCP. Attached Figure Description

[0020] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0021] The first implementation method:

[0022] Figure 1-3 A static penetrometer force loading device is shown, including a static penetrometer force body 1 with a base 2 at the bottom. The top of the base 2 has multiple first slots 3 equidistantly carved. A pressure-applying gravity bar 4 is detachably connected to the first slot 3. The top of the base 2 near the static penetrometer force body 1 has symmetrically carved through holes 6. A positioning stake 7 is rotatably connected in the through hole 6. A stake head 8 is fixedly connected to the top of the positioning stake 7. A groove 13 is carved on the top of the stake head 8. The top of the pressure-applying gravity bar 4 located directly above the first slot 3 is fixedly connected to a first buckle 5. The side end of the static penetrometer force body 1 is symmetrically fixedly connected to a second buckle 9, and the second buckle 9 and the first buckle 5 are connected by a pull rope 11.

[0023] This solution enables the following: When using the static cone penetrometer (PCP) force body 1 for geological information collection, the PCP force body 1 needs to be fixed to the ground using a loading device. The PCP force body 1 can be placed horizontally, and the pressure weight 4 can be engaged in the first slot 3, making the pressure weight 4 contact the ground. This allows for pressure testing of the base 2, preventing the PCP force body 1 from shaking. Then, the positioning stake 7 is inserted into the perforation 6. By inserting an electric drill bit into the groove 13 and starting the drill, the positioning stake 7 rotates to drill a hole in the ground, thus firmly fixing the PCP force body 1 to the ground. This effectively secures the loading device to the ground, improving the lateral stability of the PCP force body and enhancing its wind resistance.

[0024] The second implementation method:

[0025] Figure 1-4 The pull rope 11 is shown to have hooks 10 fixedly connected to both ends, and the hooks 10 are engaged with the second buckle 9 and the first buckle 5 respectively. The pull rope 11 is connected to the second buckle 9 and the first buckle 5 through the hooks 10, so that the pull rope fixes the pressure weight bar 4 to the static penetrometer force body 1, increases the force points, and maintains stability. The pressure weight bar 4 is designed with multiple specifications and weights. The design of various specifications of pressure weight bars 4 allows for the free selection of different weights of pressure weight bars 4 to reinforce 1 according to the usage environment. The pull rope 11 is designed without elasticity. The groove 13 is engaged with the through hole 6. An electric drill with a drill bit can be detachably connected in the groove 13, and the drill bit is engaged with the groove 13. The bottom end of the pressure weight bar 4 is chiseled with a second groove 12 corresponding to the first groove 3, and the second groove 12 is engaged with the first groove 3.

[0026] This solution allows for the following: When the static penetrometer body 1 is fixed to the ground using a loading device, a matching weight of the pressure bar 4 can be selected based on the usage environment. The second slot 12 at the bottom is engaged with the first slot 3 on the base 2, allowing the pressure bar 4 to be placed in the first slot 3 and in contact with the ground, thereby reinforcing the base 2. Subsequently, an electric drill is used to engage the drill bit with the groove 13 and rotate it, causing the positioning stake 7 to be inserted into the ground. The drill bit 8 is engaged with the perforation 6 and then stopped. The base 2 is fixed to the ground by the positioning stake 7. Finally, the hooks 10 on the pull rope 11 are engaged with the second buckle 9 and the first buckle 5 respectively, further reinforcing the base 2 to the ground.

[0027] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
