Technical Field
[0001] The utility model relates to the technical field of soil detection equipment, in particular to an on-site detection component for backfill soil density. Background Art
[0002] Backfill refers to the process of filling soil or other materials into an excavated or dug area to fill or reinforce the ground during construction. Backfill is usually used to fill foundations, potholes or other uneven terrain to support structures, reduce foundation bearing pressure or improve ground stability. Roadbed is an important part of road engineering. Its strength, stiffness, water stability, etc. play a vital role in the service life and safety of the road surface. Therefore, the density of the soil roadbed is an important indicator to measure the quality of the roadbed, and it is also a project that needs to be focused on during construction. However, the existing backfill density field detection component cannot control the depth of the detection probe during use. The detection probe is inserted at a different depth, which will lead to deviations in the detection results. In addition, the soil fixed spikes cannot be removed, which can easily cause harm to people during transportation. Therefore, those skilled in the art provide a backfill density field detection component to solve the problems raised in the above background technology. Utility Model Content
[0003] The utility model aims to provide a backfill soil density on-site detection component to solve the problems raised in the above-mentioned background technology.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] Preferably, the inner end of the adjusting bracket of the detection instrument main body is fixedly connected to a sliding rod on the side away from the screw rod, an adjustment block is provided on the outside of the screw rod and the sliding rod, an end of the adjustment block close to the sliding rod is fixedly connected to a depth pointer, an insertion depth scale is provided on the side of the adjusting bracket of the detection instrument main body close to the depth pointer, and one end of the adjustment block is fixedly connected to a connecting rod.
[0007] Preferably, the other end of the connecting rod is fixedly connected to the detection instrument body, the lower end of the detection instrument body is fixedly connected to the detection probe, a limiting rod is provided on the inner wall of one side of the soil fixing ground spike, one end of the limiting rod is fixedly connected to the pulling block, and the limiting rod is fixedly connected to the outer side away from the pulling block with a spring limiting convex ring.
[0008] Preferably, a spring is provided on the outer side of the limit rod near the pulling block, a limit rod slot is provided at a position corresponding to the support foot and the limit rod, a display screen is fixedly connected to the upper side of one end of the detection instrument body, and a control button is fixedly connected to the lower side of one end of the detection instrument body.
[0009] By adopting the above technical solution,
[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] 1. Start the first servo motor, which drives the screw rod to rotate, and the screw rod drives the outer adjustment block to move. The adjustment block moves on the slide rod driven by the screw rod, and the adjustment block moves downward. The adjustment block drives the connecting rod to move downward, and the connecting rod drives the detection instrument body to move downward. The detection instrument body drives the detection probe at the lower end to move downward. At the same time, the adjustment block drives the depth pointer to move downward. The detection probe goes deep into the soil through the vertical limit sleeve to detect the density of the backfill soil. The detection probe can be vertically downward without skewing through the vertical limit sleeve. The detection probe is inserted into the backfill soil for density detection. The depth of the detection probe inserted into the backfill soil can be The depth of the detection probe inserted into the backfill soil can be read out through the insertion depth scale corresponding to the depth pointer. When the detection probe is level with the backfill soil, the depth pointer points to zero on the insertion depth scale, which can accurately determine the depth of the probe inserted into the backfill soil, thereby facilitating accurate density detection and helping to ensure construction quality and soil stability. The depth information of each detection point can be recorded through the depth pointer and scale reading, providing reliable basic data for subsequent data analysis, helping to monitor and evaluate the density of the backfill soil. The scale reading of the depth pointer can timely discover the density of the backfill soil at different depths, helping to timely adjust the construction method and ensure the overall quality of the backfill soil.
[0012] 2. When it is necessary to conduct an on-site density test on the backfill soil, first align the soil fixing spikes with the support feet at the four corners of the support base, insert them to complete the installation of the soil fixing spikes, and then insert the soil fixing spikes into the ground soil to fix them, ensuring the stability of the density on-site detection component, so that the density on-site detection component will not move or fall during the test, thereby ensuring the accuracy of the test results of the density on-site detection component. When the backfill soil density test is completed, pick up the density on-site detection component and pull the pulling block of the soil fixing spike outward by hand. The pulling block drives the limit rod to loosen the limit rod slot. At the same time, the spring limiting convex ring on the outside of the limiting rod compresses the spring, removes the soil fixing ground spikes from the lower end of the supporting foot, loosens the pulling block, and the spring releases the elastic force to drive the limiting rod back to its position. During transportation, if the soil fixing ground spikes cannot be removed, it will increase the transportation difficulty of the staff and also increase the risk of accidents. The soil fixing ground spikes can be removed, so the probe body and the soil fixing ground spikes can be transported separately, which reduces the transportation burden and reduces the risk of accidents. The ground spikes can be removed and can be easily installed and disassembled, which not only saves time, but also facilitates the operation when the soil fixing ground spikes need to be replaced or repaired.

[0019] The working principle of the utility model is as follows: when it is necessary to conduct an on-site density test on the backfill soil, first align the soil fixing spikes with the supporting feet at the four corners of the supporting base, insert them to complete the installation of the soil fixing spikes, and then insert the soil fixing spikes into the ground soil for fixing, to ensure the stability of the density on-site detection component, so that the density on-site detection component will not move or fall over during the test, thereby ensuring the accuracy of the test result of the density on-site detection component, start the first servo motor, the first servo motor drives the screw rod to rotate, the screw rod drives the outer adjustment block to move, the adjustment block moves on the slide rod driven by the screw rod, and the adjustment block moves downward , the adjusting block drives the connecting rod to move downward, the connecting rod drives the main body of the detection instrument to move downward, the main body of the detection instrument drives the detection probe at the lower end to move downward, and at the same time the adjusting block drives the depth pointer to move downward, the detection probe goes deep into the soil through the vertical limit sleeve, and the density of the backfill soil is detected. The detection probe can be vertically downward without being skewed through the vertical limit sleeve. The detection probe is inserted into the backfill soil for density detection. The depth of the detection probe inserted into the backfill soil can be read through the insertion depth scale corresponding to the depth pointer. When the detection probe is level with the backfill soil, the depth pointer points to the insertion depth scale. When the probe is zero, the depth of the backfill soil can be accurately determined, thereby helping to carry out accurate density detection, helping to ensure construction quality and soil stability. Through the depth pointer and scale readings, the depth information of each detection point can be recorded, providing reliable basic data for subsequent data analysis, helping to monitor and evaluate the density of the backfill soil. Through the scale readings of the depth pointer, the density of the backfill soil at different depths can be discovered in time, helping to adjust the construction method in time and ensure the overall quality of the backfill soil. When the backfill soil density test is completed, the density field detection component is picked up, and the pulling block of the soil fixing spikes is pulled outward by hand. The moving block drives the limit rod to release the limit rod slot. At the same time, the spring limit convex ring on the outside of the limit rod compresses the spring, removes the soil fixing ground spikes from the lower end of the supporting foot, releases the pulling block, and the spring releases the elastic force to drive the limit rod back to its position. During transportation, if the soil fixing ground spikes cannot be removed, it will increase the transportation difficulty of the staff and also increase the risk of accidents. The soil fixing ground spikes can be removed, so the probe body and the soil fixing ground spikes can be transported separately, which reduces the transportation burden and reduces the risk of accidents. The ground spikes can be removed and can be easily installed and disassembled, which not only saves time, but also facilitates the operation when replacing or repairing the soil fixing ground spikes.
