Description

Technical Field

[0001] This utility model relates to the field of foundation testing technology, specifically a foundation testing device for water conservancy projects. Background Technology

[0002] The foundation refers to the soil or rock mass that supports the foundation of a building. Soil layers that serve as building foundations are divided into rock, gravelly soil, sandy soil, silty soil, cohesive soil, and artificial fill. Foundations are divided into two categories: natural foundations and artificial foundations (composite foundations). Natural foundations are natural soil layers that do not require reinforcement, while artificial foundations require reinforcement treatment. Common methods include stone chip cushion layers, sand cushion layers, and backfilling and compaction of mixed lime-soil. In the construction of foundations for water conservancy projects, it is necessary to frequently test the foundation to prevent problems with the quality of the water conservancy project caused by the foundation.

[0003] Chinese patent CN218990117U discloses a foundation testing device for hydraulic engineering. The device is placed on the surface of the foundation. The location of the anti-splash tube determines the testing point. A PLC controller starts a motor, which lifts the foundation testing probe upwards via a lifting plate. The probe then falls from a height. Once inside the anti-splash tube, air inside is expelled through arc-shaped vents, reducing resistance during the probe's descent. After the probe impacts the foundation surface, a linear displacement sensor detects the maximum downward distance traveled, determining the depth of penetration and thus assessing the foundation's quality. The anti-splash tube also prevents flying stones from injuring personnel, improving safety and reducing the impact of the anti-splash components on the probe's impact force, ensuring accurate test results.

[0004] While the aforementioned solution employs a Z-shaped chute to allow the lifting plate to move freely at its highest and lowest points, enabling the guide slide to move synchronously with the detection probe, the fact that the lifting plate is only unrestricted at its highest and lowest points results in a fixed detection height for the probe, leading to limited data acquisition and poor accuracy. Therefore, we provide a foundation testing device for hydraulic engineering projects to address these issues. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1-4 As shown, this utility model provides a technical solution: a foundation testing device for water conservancy projects, including a base plate 1, a working plate 7, a connecting component, a lifting component, and a load-bearing component.

[0031] A control box 2 is fixedly connected to the base plate 1, and a reinforcing plate 18 is fixedly connected to the base plate 1. The end of the reinforcing plate 18 away from the base plate 1 is fixedly connected to the control box 2. The reinforcing plate 18 supports the connection between the base plate 1 and the control box 2, thereby improving the stability of the control box 2 on the base plate 1. A sliding groove 3 is provided on the control box 2, and a lifting plate 6 is slidably connected in the sliding groove 3.

[0032] The working plate 7 is equipped with a detection probe 8. The bottom end of the detection probe 8 is a pointed tip. The hardness of the foundation can be detected by the depth to which the tip of the detection probe 8 is inserted into the foundation.

[0033] The connecting assembly is set on the lifting plate 6. The working plate 7 is detachably installed on the lifting plate 6 through the connecting assembly. The connecting assembly includes a support 9 fixedly connected to the lifting plate 6. A second motor 10 is installed on the support 9. A bidirectional lead screw 11 is installed on the output shaft of the second motor 10. Two L-shaped clamping plates 12 are threadedly connected to the bidirectional lead screw 11. A moving groove 17 is opened on the working plate 7. The bottom end of the L-shaped clamping plate 12 is slidably connected to the moving groove 17.

[0034] The bidirectional lead screw 11 is a rod with opposite threads at both ends. The output shaft of the second motor 10 drives the bidirectional lead screw 11 to rotate, which enables the two L-shaped clamping plates 12 to move closer to each other or further away from each other in the moving groove 17.

[0035] Two L-shaped clamping plates 12 have their sides close to each other and abut against the two sides of the working plate 7. The bottom end of the L-shaped clamping plate 12 is provided with a hook, and the hook abuts against the bottom surface of the working plate 7. When the two L-shaped clamping plates 12 are close to each other, the L-shaped clamping plates 12 can be abutted against the working plate 7, and the hook of the L-shaped clamping plate 12 abuts against the ground of the working plate 7 to complete the connection between the lifting plate 6 and the working plate 7. After the two L-shaped clamping plates 12 move away from each other, the connection between the working plate 7 and the lifting plate 6 is released, so that the working plate 7 moves downward under the influence of gravity.

[0036] The lifting assembly is mounted on the control box 2. The detection probe 8 is moved to the detection position by lifting the lifting plate 6. The lifting assembly includes a first motor 4 mounted on the control box 2. The output shaft of the first motor 4 is equipped with a one-way screw 5, and the one-way screw 5 is rotatably connected in the slide groove 3. The end of the lifting plate 6 away from the working plate 7 is threadedly connected to the one-way screw 5.

[0037] The output shaft of the first motor 4 drives the one-way screw 5 to rotate, causing the lifting plate 6 to move up and down within the slide groove 3. When the lifting plate 6 moves upward, the detection probe 8 can be moved to different heights for multiple tests as needed to meet the requirements of detection accuracy. When the lifting plate 6 moves downward, it can be pressed against the working plate 7, and the lifting plate 6 and the working plate 7 are connected together by the connecting assembly to perform the above-mentioned movement.

[0038] Two guide rods 15 are slidably connected to the working plate 7. A limit plate 16 is provided above the working plate 7, and the top ends of the two guide rods 15 are fixedly connected to the limit plate 16. When the working plate 7 moves downward, it can slide on the guide rods 15, thereby improving the stability of the movement of the working plate 7.

[0039] The load-bearing component is set on the working plate 7 and is used to adjust the descent force of the detection probe 8 at the detection position. The load-bearing component includes a mounting rod 13 fixedly connected to the working plate 7, and a weight 14 is inserted into the mounting rod 13.

[0040] By inserting weights 14 of different weights into the mounting rod 13, the load on the working plate 7 can be increased, thereby applying different descent forces to the detection probe 8 to meet the requirements of detection accuracy.

[0041] A positioning plate 19 is fixedly connected to the base plate 1. The positioning plate 19 has a positioning hole 20, which is adapted to the detection probe 8. The detection position is positioned by the positioning hole 20, and the detection probe 8 can pass through the positioning hole 20 and contact the foundation during detection.
