Description

Technical Field

[0001] The invention belongs to the technical field of road layer detection, and in particular relates to a road construction layer detection device and a layer detection method. Background Art

[0002] Road construction layer detection is a key link in highway construction, which mainly involves detecting the actual conditions of roadbed construction to ensure construction quality and safety. Traditional road construction layer detection methods mainly rely on drilling, sampling and other means. In recent years, with the rapid development of engineering geophysical exploration technology, especially the application of non-destructive detection technologies such as ground penetrating radar, geological radar detection method, and acoustic wave detection method, a more efficient and accurate solution is provided for road construction layer detection. After searching, the publication number CN116538970A discloses a ground penetrating radar detection and acceptance method for the thickness of road structure layers, including the following steps: calibrating the dielectric constant of the road structure layer at each measuring point; fitting the dielectric constant of each measuring point with a normal distribution curve; testing the two-way travel time of the electromagnetic wave at the thickness acceptance measuring point; calculating the probability distribution interval of the two-way travel time of the thickness acceptance qualified interval; calculating the acceptance probability of the measuring point, and judging the thickness qualification.

[0003] In the prior art, since radar detectors need to be close to or in contact with the ground for mobile detection when in use, it is necessary to clean the stones on the road where the device moves before performing layer detection. If the stones are not cleaned, it is easy to cause damage to the radar detector when the device moves.

[0014] A layer exploration method for road construction, characterized in that the method is as follows: Step 1: Place the radar detector for road layer detection on one side of the mobile mechanism, and use the electric push rod installed between the bracket and the rotating rod to push the rotating rod to rotate and adjust with the main axis as the center. Use the principle of lever to make the rotating rod rotate and drive the obstacle removal inclined guide plate to flip, so that the lowest point of the vertical plane of the obstacle removal inclined guide plate is higher than the highest point of the vertical plane of the frame. After the structural deformation is completed, the height of the support plate is lowered by rotating the screw rod, so that the device completes the preparation work before assembly; Step 2: Push the lifting mechanism and the moving mechanism to one side by pushing the handrail, so that the radar detector enters the interior of the frame, and then use the baffle to block and limit the position of the radar detector inside the frame. Raise the height of the pallet by turning the screw, and use the pallet to lift the radar detector from the ground so that the bottom of the radar detector maintains a certain height with the ground. Manually adjust the position of the slide bar on the positioning bolt, and after adjustment, turn the positioning bolt to cooperate with the pallet to clamp and limit the radar detector, and complete the assembly of the moving mechanism and the radar detector. After the assembly is completed, restart the electric push rod, and the obstacle clearing inclined guide plate is reset under the drive of the rotating rod, so that the lowest point of the obstacle clearing inclined guide plate after adjustment is lower than the lowest point of the bottom of the radar detector. Step 3: After connecting the console to an external power source, use the GPS locator to detect the location of the device, use the radar detector to use ultra-high frequency electromagnetic waves to detect the distribution of underground media, push the device to move by pushing the handrail to achieve continuous detection, and use the console to display the detection results to the user. During the movement of the device, use the obstacle removal inclined guide plate to push the stones in the moving direction of the device to avoid stones from damaging the radar detector; Step 4: Start the motor to drive the core barrel to rotate, start the motor, and the motor moves the mounting plate up and down through the screw rod to adjust the drilling mechanism. During the adjustment process, the drilling mechanism is driven to move up and down. During the downward movement of the mounting plate, the slider is driven to move downward at the same time. The mudguard that loses the slider limit automatically moves downward and contacts the ground under the guidance of its own weight, thereby separating the radar detector from the drilling mechanism. After the drilling mechanism is inserted into the ground, the soil layer is taken out from the ground, thereby realizing drilling detection. During the upward movement of the drilling mechanism, the slider is used to drive the mudguard to move upward, so that the mudguard is separated from the ground for easy movement and adjustment.

[0015] Technical effects and advantages of the present invention: 1. The present invention installs an adjustable obstacle-clearing mechanism on one side of the moving mechanism. When in use, the obstacle-clearing inclined guide plate can be flipped and adjusted according to needs through the cooperation of the rotating rod, the main shaft, the electric push rod and the bracket. After the structural deformation is completed, the radar detector can be assembled. After the assembly is completed, the electric push rod is restarted, and the obstacle-clearing inclined guide plate is reset under the drive of the rotating rod, so that the lowest point of the obstacle-clearing inclined guide plate after adjustment is lower than the lowest point of the bottom of the radar detector. When moving, the obstacle-clearing inclined guide plate can guide and divert stones to the outside to achieve shielding and protection of the radar detector; 2. The present invention uses a drilling mechanism installed inside the lifting mechanism. During the operation of the drilling mechanism, the core barrel rotates rapidly, and the mounting plate moves up and down driven by the screw rod, thereby realizing drilling and sampling of the road. After the sample inside the core barrel is taken out, layer detection is realized. The radar detector can emit high-frequency electromagnetic waves, and the geological target is detected by studying the time, speed and dynamic characteristics of the wave propagation underground, thereby improving the working efficiency of road layer detection; 3. The present invention uses a mudguard slidably installed inside the limit groove and a slider inserted into the slide groove. When the drilling mechanism moves downward, the slider is simultaneously driven to move downward inside the slide groove. The mudguard that loses the support of the slider automatically falls down and contacts the ground under the action of its own gravity, thereby isolating the radar detector from the drilling mechanism, preventing the soil thrown out during the drilling mechanism processing from splashing onto the radar detector, and keeping the radar detector clean.

9. A layer exploration method for road construction, characterized in that: The method is as follows: Step 1: Place a radar detector (3) for road layer detection on one side of the mobile mechanism (1); use an electric push rod (504) installed between the bracket (505) and the rotating rod (502) to push the rotating rod (502) to rotate around the main axis (503) as the center; use the principle of a lever to drive the obstruction removal inclined guide plate (501) to flip during the rotation of the rotating rod (502), so that the lowest point of the vertical plane of the obstruction removal inclined guide plate (501) is higher than the highest point of the vertical plane of the frame (101); after the structural deformation is completed, the height of the support plate (103) is lowered by rotating the screw rod (104), so that the device completes the preparation work before assembly; Step 2: Push the lifting mechanism (6) and the moving mechanism (1) to one side by pushing the handrail (7) so that the radar detector (3) enters the interior of the vehicle frame (101), and then use the baffle (107) to block and limit the position of the radar detector (3) inside the vehicle frame (101). The height of the support plate (103) is raised by rotating the screw rod (104), and the radar detector (3) is lifted from the ground by using the support plate (103), so that the bottom of the radar detector (3) maintains a certain height from the ground. , manually adjusting the position of the slide bar (203) on the positioning bolt (204), rotating the positioning bolt (204) after adjustment to cooperate with the support plate (103) to clamp and limit the radar detector (3), completing the assembly of the moving mechanism (1) and the radar detector (3), restarting the electric push rod (504) after the assembly is completed, and the obstacle clearing inclined guide plate (501) is reset under the drive of the rotating rod (502), so that the lowest point of the obstacle clearing inclined guide plate (501) after adjustment is lower than the lowest point of the bottom of the radar detector (3); Step 3: After connecting the console (8) to an external power source, the location of the device is detected using the GPS locator (4), and the distribution of underground media is detected using the radar detector (3) using ultra-high frequency electromagnetic waves. The device is pushed to move by the push handle (7) to achieve continuous detection. The detection results are displayed to the user using the console (8). During the movement of the device, the obstacle removal inclined guide plate (501) is used to push the stones in the moving direction of the device to prevent the stones from causing damage to the radar detector (3); Step 4: Start the motor (902) to drive the coring barrel (903) to rotate, start the motor (603), and the motor (603) moves the mounting plate (901) up and down through the screw rod (602). During the adjustment process, the drilling mechanism (9) is driven to move up and down. During the downward movement of the mounting plate (901), the slider (12) is driven to move downward at the same time. The mudguard (10) that loses the limit of the slider (12) automatically moves downward under the guidance of its own weight and contacts the ground, so as to separate the radar detector (3) from the drilling mechanism (9). After the drilling mechanism (9) is inserted into the ground, the soil layer is taken out from the ground, thereby realizing drilling detection. During the upward movement of the drilling mechanism (9), the slider (12) is used to drive the mudguard (10) to move upward, so that the mudguard (10) is separated from the ground, so as to facilitate movement and adjustment.
