Technical Field

[0002] The light dynamic penetration method uses a certain hammer energy to drive a main probe rod of a certain specification into the soil. According to the depth reached by the main probe rod, the type of soil layer is determined, the engineering properties of the soil are determined, and the bearing capacity and uniformity of the foundation soil are comprehensively evaluated. This method can quickly and economically obtain the physical and mechanical parameters of the soil, and has a wide range of application prospects.

[0003] In the prior art, there is a light dynamic sounding instrument including a sounding rod, a core hammer and a hammer pad. The sounding rod is the main part of the light dynamic sounding instrument, which is used to drive the probe into the soil for testing. The core hammer is an important component on the sounding rod. It is usually located at the center of the sounding rod and can transfer the energy of the hammer to the tip of the sounding rod, thereby driving the probe into the soil. The core hammer is usually made of high-quality metal to ensure that it can withstand multiple hammering without damage. The hammer pad is usually located below the core hammer to reduce the impact force during hammering, thereby protecting the sounding rod and the probe from damage due to excessive impact force.

[0004] With regard to the above-mentioned related technologies, during use, one person needs to hold the feeler rod and keep it in a vertical state, while another person operates the core hammer, which is inconvenient to operate. Utility Model Content

The feeler rod 1 passes through the through hole 46. The aperture of the through hole 46 is equal to the diameter of the feeler rod 1. The feeler rod 1 is driven into the soil by the hammering energy of the core hammer 2 on the feeler rod 1. In the present application, a stabilizing vehicle 3 is added so that a single person can operate the feeler rod 1 and the core hammer 2. That is, by pushing the stabilizing vehicle 3 to a suitable position, the feeler rod 1 is passed through the through hole 46 so that the feeler rod 1 is supported.

[0040] The implementation principle of a ground light dynamic penetration instrument in the embodiment of the present application is:

[0041] The bottom plate 31 is tilted with the axis of the roller 32 as the rotating axis, so that the brake block 35 leaves the ground. At this time, the roller 32 and the side wheel 34 are in contact with the ground, which can push the stabilizing vehicle 3 to move. When the probe rod 1 reaches the soil to be tested, it is inserted into the through hole 46. Since the through hole 46 limits the probe rod 1 to move only vertically, the probe rod 1 can be vertically inserted into the soil. The tip 111 of the probe rod 1 contacts the soil to be detected, and the core hammer 2 is lifted to the limit plate 121 by applying force. The core hammer 2 is withdrawn, so that the core hammer 2 falls due to gravity and strikes the hammer pad 112. The energy of the hammer strikes causes the probe rod 1 to be inserted into the soil. The type of soil layer is determined according to the depth reached by the number of hammer strikes of the probe rod 1, the engineering properties of the soil are determined, and a comprehensive evaluation is made on the bearing capacity and uniformity of the foundation soil.

[0042] Furthermore, the stabilizing block 5 cooperates with the through hole 46, so that the sounding rod 1 can be more stably vertically probed. As the sounding rod 1 probes downward, the stabilizing block 5 can be adjusted to adaptively adjust the sounding rod 1 to probe deeper into the soil.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
