Description

Technical Field

[0001] This utility model relates to the technical field of soil testing devices, specifically a soil testing device for engineering construction. Background Technology

[0002] In engineering construction, such as road, bridge, building, and water conservancy projects, accurate and efficient soil testing is an indispensable key link in ensuring project safety, optimizing design, and controlling construction quality. The fundamental purpose of soil testing is to obtain the physical, mechanical, and chemical properties of the foundation soil, providing a scientific basis for engineering decisions.

[0003] While soil testing is crucial, existing technologies have significant shortcomings in practical applications, particularly in terms of mobility, automation, and real-time performance. Firstly, traditional testing equipment suffers from poor mobility. Large drilling rigs and static cone penetration tests are bulky and require specific site conditions. Moving and relocating them in narrow, muddy, or soft, uneven construction areas is extremely difficult, heavily reliant on towing vehicles and manual dispatch, resulting in low efficiency and insufficient flexibility. Secondly, sampling largely relies on manual operation, leading to high labor intensity, inconsistent sampling standards, and the need for samples to be sent to laboratories for analysis. This results in long data acquisition cycles and significant delays, failing to meet the urgent need for real-time feedback in modern construction. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a soil testing device for engineering construction, which has the advantages of high mobility, minimal impact from terrain, and rapid sampling and testing, thus solving the problems of difficult sampling and long testing cycles in complex environments in existing technologies.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a soil testing device for engineering construction, comprising a frame, wherein a transmission motor for transmission is mounted on the frame, the transmission motor is connected to a transmission wheel, and the transmission wheel is connected to a transmission track. The vehicle frame is equipped with a support frame for installation, and the support frame is equipped with a sampling component for soil sampling. The vehicle frame is also equipped with a sampling frame for collecting samples and a battery for power supply.

[0006] Furthermore, the sampling component includes a mounting unit, and the mounting unit is provided with a transmission unit for transmission. The installation unit includes a guide tube fixedly connected to the support frame. The guide tube is located on one side of the sampling frame, and its bottom is also provided with a sampling plate for automatically scooping the sample into the sampling frame.

[0007] Furthermore, the transmission unit includes a mounting base fixedly mounted on the mounting unit. A detection probe for detection is provided at the bottom of the mounting base. The detection probe is located above the sampling frame. An electric push rod for transmission is provided at the top of the mounting base. A sampling element is provided at the end of the electric push rod.

[0008] Furthermore, the sampling component consists of a tube, with a connecting plate horizontally arranged at the top of the tube, which is fixedly connected to the end of the electric push rod through the connecting plate; The tube body is slidably connected inside the guide tube, and a sampling groove is also provided on the tube body, with the sampling piece slidably connected inside the sampling groove.

[0009] Furthermore, the bottom of the sampling piece is a concave arc-shaped surface, and its outer circumference is in contact with the inner diameter of the tube.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects: I. This soil testing device for engineering construction enables autonomous movement within complex construction sites via a tracked chassis, overcoming the drawbacks of traditional equipment, such as difficult relocation and reliance on manual labor. The integrated electric push rod-driven sampling assembly, combined with a unique sampling plate structure, automates the entire process from "pressing in the sample" to "lifting and scraping" and finally "collecting the sample," requiring no manual intervention. This not only frees operators from heavy physical labor but also avoids prolonged exposure to potentially hazardous construction environments, significantly improving operational safety.

[0011] II. This soil testing device for engineering construction highly integrates a mobile platform, an automatic sampling mechanism, and a real-time detection probe into one unit. Upon arrival at the site, the device can immediately perform its tasks. After sampling, soil samples are directly and quickly collected into designated frames, resulting in a streamlined process that avoids sample contamination and human disturbance. Simultaneously, the detection probe can perform in-situ or near-in-situ analysis of key soil parameters, acquiring real-time data. This effectively solves the serious lag problem caused by the traditional "field sampling-laboratory analysis" process, providing immediate data support for rapid decision-making at the construction site, thereby better serving construction quality and safety control.

[0014] 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.

[0015] Please see Figure 1-3 ,like Figures 1 to 3 As shown, the present invention provides a soil testing device for engineering construction, which mainly includes a frame 1, a transmission system, a sampling component 2, and an energy system.

[0016] The chassis 1 serves as the basic support structure for the entire device. A drive wheel 12, driven by a drive motor 11, is mounted at its bottom, and a drive track 13 is fitted onto the drive wheel 12. This tracked drive structure gives the device strong off-road capability, enabling it to move and steer stably on complex terrains such as mud, uneven surfaces, and slopes commonly found at construction sites. A battery 14 is installed inside the chassis 1 to provide power to the motors, probes, and push rods of the entire device, enabling cable-free operation. A support frame 15 is fixed to the upper part of the chassis 1 for mounting the sampling assembly 2. In addition, one or more sampling frames 16 are also provided on the chassis 1 for collecting the collected soil samples.

[0017] The sampling component 2 is a core functional module, mainly composed of a transmission unit 21 and an installation unit 22.

[0018] The mounting unit 22 includes a guide tube 221 vertically fixed to the support frame 15. At the bottom end of the guide tube 221, near the sampling frame 16, a sampling plate 222 is hinged. The bottom of the sampling plate 222 is designed with a concave arc surface, which allows it to more effectively support and scrape soil samples.

[0019] The transmission unit 21 includes a mounting base 211 fixedly mounted on the top of the guide tube 221. An electric push rod 213 is fixed to the top of the mounting base 211, extending vertically downwards through the mounting base 211 into the guide tube 221. A sampling element 214 is fixedly connected to the end of the push rod via a connecting plate. The sampling element 214 is essentially a tubular structure with a longitudinal sampling groove on its wall. Driven by the electric push rod 213, the sampling element 214 can slide up and down within the guide tube 221.

[0020] The work process is as follows: Movement and positioning: The drive motor 11 starts and moves the device to the predetermined sampling point via the drive track 13.

[0021] Sampling: The electric push rod 213 is activated, pushing the sampling component 214 downward, pressing its lower end into the soil, and the soil enters the inside of the tube.

[0022] Lifting and Scraping: After soil sampling is completed, the electric push rod 213 retracts, pulling the sampling element 214 and the soil sample inside it upwards. When the soil sample rises with the sampling element 214 to contact the sampling plate 222, the sampling plate 222, fixed on the guide tube 221, will lock the soil sample, preventing it from continuing to rise with the sampling element 214. As the sampling element 214 continues to rise, the arc-shaped bottom surface of the sampling plate 222 will completely and automatically scrape off the soil sample inside the tube.

[0023] Sample collection and testing: The soil sample column that has been shoveled falls directly into the sampling frame 16 below under the influence of gravity, completing the automatic collection of the sample. At the same time, the detection probe 212 (such as a moisture content sensor, conductivity sensor, etc.) fixed to the bottom of the mounting base 211 can perform real-time data detection on the in-situ sample or the collected sample during or after sampling, and wirelessly transmit the results to the control terminal.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
