Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a lightweight power penetrometer probe rod extraction device. Background Technology

[0002] With increased infrastructure investment, the number of engineering construction projects is growing. For shallow foundation engineering, the bearing capacity of the foundation is usually tested using a plate load test, which is time-consuming and requires significant manpower and resources. Lightweight dynamic cone penetration testing (DCPT) uses a specific hammer impact energy to drive a cone probe of a certain size into the soil. The depth reached based on the number of blows determines the soil layer type. This method is faster, saves manpower and resources, and provides a comprehensive evaluation of the foundation soil. However, after the lightweight DCPT probe is driven into the soil, it needs to be manually pulled out, which is time-consuming, labor-intensive, and inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a lightweight power penetrometer probe rod extraction device to solve the problem that the probe rod of a lightweight power penetrometer is difficult to extract.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A lightweight power penetrometer probe rod extraction device includes a support member, a through-hole jack, a pressure plate, and an anchor. The support member is used to support the probe on the ground. The through-hole jack is located at the upper end of the support member. The pressure plate is located at the upper end of the through-hole jack. The anchor is located on the pressure plate. After passing through the support member, the through-hole jack, and the pressure plate, the anchor is fixed to the pressure plate. The through-hole jack drives the pressure plate to rise, and the probe rod is pulled out of the soil.

[0006] Furthermore, the support member is provided with a support member hole for the probe rod to pass through.

[0007] Furthermore, the support includes a support stool, which is supported on the ground, and the support hole is located at the center of the support stool.

[0008] Furthermore, the pressure plate is provided with a pressure plate hole for the probe to pass through, and the pressure plate hole is located at the center of the pressure plate.

[0009] Furthermore, the support member, through-hole jack, pressure plate, and anchor are detachable.

[0010] Furthermore, after the anchor passes through the probe rod, a clamp is inserted between the anchor and the probe rod to lock the anchor and the probe rod together.

[0011] The beneficial effects of this utility model are:

[0012] This utility model discloses a lightweight, power-driven penetrometer probe extraction device. A through-hole jack drives a pressure plate upward, which in turn lifts the anchor and probe together, easily extracting the probe from the soil. Compared to existing methods requiring manual extraction, this invention saves time and effort, significantly improving work efficiency and reducing the workload of operators. Furthermore, the device has a simple structure, is easy to disassemble and assemble, facilitates transportation and storage, and its components are detachable, allowing for easy replacement of different specifications as needed, thus offering high practicality and flexibility.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Please see Figures 1 to 3 This utility model provides a lightweight power penetrometer probe rod extraction device, including a support 1, a through-hole jack 2, a pressure plate 3, and an anchor 4.

[0020] The support member 1 is used to support the device on the ground. Specifically, the support member 1 includes a support stool 11, which is firmly supported on the ground, providing a stable support foundation for the entire device. A support hole 12 is provided at the center of the support stool 11 for the probe rod 5 to pass through.

[0021] The through-hole jack 2 is located at the upper end of the support member 1, that is, at the upper end of the support stool 11. The through-hole jack 2 has sufficient lifting force to drive the pressure plate 3 to rise.

[0022] The pressure plate 3 is located at the upper end of the through-hole jack 2. The pressure plate 3 has a pressure plate hole 31 at its center for the probe rod 5 to pass through. The pressure plate 3 is used to bear the lifting force of the through-hole jack 2 and transmit this force to the anchor 4.

[0023] Anchor 4 is installed on the pressure plate 3. After passing through the support member 1, the through jack 2, and the pressure plate 3, anchor 4 is fixed to the pressure plate 3. Specifically, after anchor 4 passes through probe 5, a clamp is inserted between anchor 4 and probe 5 to lock anchor 4 and probe 5, ensuring a firm connection between anchor 4 and probe 5.

[0024] In use, after the probe is driven into the soil to a certain depth, the excess probe is removed. The support is then passed through the remaining probe in the soil and placed on the ground. The through-hole jack 2, the pressure plate 3, and the anchor 4 are then installed in sequence. The probe 5 is then passed through the support hole 12 and the pressure plate hole 31, and then secured with the anchor 4. The through-hole jack 2 is then activated, driving the pressure plate 3 to rise. The pressure plate 3, through the anchor 4, drives the probe 5 to rise, thus pulling the probe 5 out of the soil.

[0025] Furthermore, the support component 1, the through jack 2, the pressure plate 3, and the anchor 4 are detachable, which facilitates transportation and storage, and also makes it easy to replace different specifications of components according to actual needs.

[0026] In summary, the lightweight power penetrometer probe extraction device of this invention uses a through-hole jack 2 to drive the pressure plate 3 upward, thereby pulling the probe 5 out of the soil. This saves time and effort and improves work efficiency. Furthermore, the device has a simple structure, is easy to disassemble and assemble, and is convenient for transportation and storage, making it suitable for a wide range of applications.

[0027] Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model are within the protection scope of this utility model.
