Testing can directly reveal whether the reinforcement layer meets the intended design requirements and effectively improves the structure's load-bearing capacity, stability, and durability.

[0003] In the process of realizing this application, the inventors discovered the following problems with the existing technology: the existing testing methods and equipment often have insufficient testing accuracy, complex operation, and single testing items that cannot be completed in one go, and cannot comprehensively and accurately determine whether the foundation of the reinforcement layer is reliable.

[0004] Therefore, those skilled in the art have provided a device for testing the reliability of reinforced foundation layers to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a reliability testing device for reinforced foundations. This device integrates multiple testing functions into one testing mechanism, which improves testing efficiency, and the fixing mechanism makes the data during load testing more stable.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reliability testing device for reinforced foundation, comprising a testing mechanism and a fixing mechanism. The testing mechanism includes a control console and a baffle. A base plate is fixedly connected to the bottom of the control console. An ultrasonic-rebound integrated testing instrument and a ground penetrating radar are fixedly connected to the front end of the control console. A fixing plate is movably connected to the top of the base plate at the front end of the control console. A reaction frame is fixedly connected to the top of the fixing plate.

[0007] The fixing mechanism includes two screws, with fixing blocks threadedly connected to the outer walls of the two screws, and protruding plates fixedly connected to the outer walls of the two fixing blocks.

[0008] Furthermore, a jack is fixedly connected to the rear end face of the reaction frame, and the rear end face of the jack is fixedly connected to the center of the front end face of the retaining frame.

[0014] This utility model has the following beneficial effects:

[0015] 1. The present invention proposes a reinforcement layer foundation reliability testing device. The entire device is moved to a simulated reinforcement layer testing area to ensure that the entire testing device is placed stably. Ground penetrating radar scans the reinforcement layer foundation and transmits the scanning data to the control console. The approximate location of the cracks can be viewed through the display screen on the top of the control console. Then, an ultrasonic-rebound integrated testing instrument is used to view the specific location of the cracks and a rebound test is performed to obtain the estimated value of the concrete strength.

[0016] 2. The present invention proposes a reliability testing device for reinforced foundation. During load testing, rotating two handles drives the screw to rotate, causing the tip of the screw to penetrate into the soil and fix the overall structure. The jack starts working, and the output end pushes the reaction frame against the reinforced foundation. The display screen on the top of the control console detects whether there are any abnormalities such as cracks or excessive deformation in the reinforced foundation. Multiple testing devices are integrated together, shortening the overall testing time and improving testing efficiency.

Detailed Implementation

[0023] 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.

[0024] Reference Figures 1-4 The present invention provides an embodiment of a reinforcement layer foundation reliability testing device, comprising a testing mechanism 1 and a fixing mechanism 2. The testing mechanism 1 includes a control console 101 and a baffle 106. A base plate 111 is fixedly connected to the bottom of the control console 101. An ultrasonic-rebound integrated tester 110 and a ground penetrating radar 105 are fixedly connected to the front end of the control console 101. A fixing plate 107 is movably connected to the top of the base plate 111 at the front end of the control console 101. A reaction frame 108 is fixedly connected to the top of the fixing plate 107. The fixing mechanism 2 includes two screws 204. Fixing blocks 202 are threadedly connected to the outer walls of the two screws 204. Protrusion plates 201 are fixedly connected to the outer walls of the two fixing blocks 202.

[0025] Specifically, the overall structure is moved to the simulated reinforced foundation testing area using four wheels 104, ensuring the testing vehicle is parked stably. First, the ground-penetrating radar 105 is activated to scan the reinforced foundation and acquire information. After the scan is completed, the data is transmitted to the control console 101. The display screen on the top of the control console 101 is used to preliminarily determine whether there are obvious defects such as voids or cracks in the reinforced layer, and to check the approximate location of the cracks. Then, the ultrasonic-rebound integrated testing instrument 110 is used to check the specific location of the cracks and to conduct a rebound test to calculate the estimated value of the concrete strength. This determines whether the concrete strength of the reinforced layer meets the design requirements. Then, the load test is performed on the reinforced foundation. The two handles 203 rotate, driving the screw 204 to rotate, causing the sharp end of the screw 204 to penetrate into the ground and fix the overall structure. The jack 109 works to push the reaction frame 108 forward, pressing against the reinforced foundation for a period of time. The pressure sensor transmits the data to the control console 101 to detect whether the reinforced foundation has cracks, excessive deformation, or other abnormalities.

[0026] Reference Figures 1-4A jack 109 is fixedly connected to the rear end face of the reaction frame 108. The rear end face of the jack 109 is fixedly connected to the center of the front end face of the stop frame 106. The bottom of the stop frame 106 is fixedly connected to the rear top of the fixed plate 107. Multiple bolts 112 are threadedly connected to the inner wall of the top of the base plate 111. Nuts 113 are threadedly connected to the outer wall of the multiple bolts 112. The multiple bolts 112 are rotatably connected to the inner wall of the fixed plate 107. Handles 203 are fixedly connected to the top of the two screws 204. 04 The bottom is conical with the tip pointing downwards. The front end of the convex plate 201 is fixedly connected to the rear end of the base plate 111. The top of the base plate 111 is fixedly connected to the rear end of the control console 101 with a handle 102. The bottom of the base plate 111 is fixedly equipped with wheels 104 near the four corners. The top and rear end of the control console 101 is fixedly equipped with a display screen and a control module. The ultrasonic-rebound integrated detector 110 has a built-in high-precision ultrasonic sensor and a rebound meter. The ground penetrating radar 105 has an antenna 103 fixedly equipped on its top.

[0027] Specifically, multiple bolts 112 and multiple nuts 113 ensure that the reaction frame 108 and jack 109 can be disassembled from the overall equipment. The bottom of the two screws 204 is conical, which can be easily driven into the soil to fix the entire equipment. The overall equipment will not move backward when the reaction frame 108 and jack 109 are working. The handle 203 makes it easier to rotate the screws 204. The height of the antenna 103 is adjustable to adapt to the detection needs of different depths.

[0028] Working principle: Hold the handle 102 and push the base plate 111. The base plate 111 moves through the four wheels 104 at the bottom, which in turn moves the equipment on top. When it reaches the area to be inspected, the ground penetrating radar 105 is used to scan the foundation of the reinforcement layer. The scan obtains information about the internal structure and possible defects of the reinforcement layer. After the scan is completed, the data is transmitted to the control console 101. The display screen on the top of the control console 101 is used to make a preliminary judgment on whether there are obvious defects such as voids and cracks in the reinforcement layer. The approximate location of the cracks is checked. Then, the ultrasonic-rebound integrated detector 110 is used to check the specific location of the cracks. At the same time, a rebound test is performed. Rebound test points are evenly distributed on the concrete surface, and each test point needs to be rebounded 16 times. The average value of the 16 times is taken as the rebound value of that point. Through the rebound strength curve, the estimated value of the concrete strength is calculated, and it can be determined whether the concrete strength of the reinforcement layer meets the design requirements.

[0029] Secondly, after the strength test is completed, the load test of the reinforced foundation can be carried out. First, rotate the two handles 203 to drive the bottom screw 204 to rotate, so that the bottom of the screw 204 is driven into the ground to fix the overall structure. Then, start the jack 109. The output end of the jack 109 pushes the reaction frame 108 forward to push against the reinforced foundation for a period of time. The data is transmitted to the control console 101 through the pressure sensor to detect whether the reinforced foundation has cracks, excessive deformation or other abnormalities. The bolts 112 and nuts 113 facilitate the disassembly of the reaction frame 108 and the jack 109.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
