Description

Technical Field

[0001] The present invention relates to the field of land engineering technology, and in particular to a land improvement engineering detection device and a detection method. Background Art

[0002] Land engineering refers to the materials, equipment, survey, design, construction, maintenance, repair and other technologies used, as well as the objects of engineering construction, that is, various engineering facilities built above or below the ground, on land or in water, which directly or indirectly serve human life, production, military affairs and scientific research. In land engineering, it is necessary to level the ground, which can be used to compact sandy, semi-sticky and sticky soils, roadbed stabilized soil and asphalt concrete pavement layers.

[0003] Land improvement project inspections include inspections of land flatness, land surface hardness, and density at different depths inside the land. During the actual inspection process, operators are required to use a variety of instruments to complete the inspection results, which is very inconvenient. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a land consolidation project detection device and a detection method, which solves the technical problem that land consolidation project detection requires the use of multiple instruments to detect multiple items, which is very inconvenient.

[0006] (II) Technical solution

[0007] In order to achieve the above object, the main technical solutions adopted by the present invention include:

[0008] In a first aspect, an embodiment of the present invention provides a land reclamation engineering detection device, comprising a detection vehicle body that moves along the reclamation ground, a ground flatness detection component disposed at the lower end of the detection vehicle body and arranged along the width direction of the detection vehicle body, a marking component disposed at the side end of the detection vehicle body and marking the ground, a ground hardness detection component disposed at the lower end of the detection vehicle body and detecting the ground hardness as the detection vehicle body moves, a soil depth sampling component disposed at the side end of the detection vehicle body and performing an array soil sampling on the ground to be detected as the detection vehicle body moves, and a soil column density detection component disposed at the upper end of the detection vehicle body and receiving and detecting the soil column taken out by the soil depth sampling component, the ground flatness detection component continuously detects the surface flatness as the detection vehicle body moves, and the marking component marks the ground when the ground flatness detection component and the ground hardness detection component detect abnormalities.

[0009] A land consolidation engineering detection device proposed in an embodiment of the present invention, when the detection device is used to detect the land consolidation engineering, the detection vehicle body is moved to the ground to be detected, the detection path and the ground hardness detection points and the soil column sampling points are planned, and then the detection vehicle body is moved according to the planned path, and the ground flatness detection component is started while moving, and the ground flatness detection component continuously detects the surface flatness as the detection vehicle body moves, and when the detection is abnormal, the abnormal ground is marked by the marking component and electronically recorded, when the detection vehicle body moves to the ground hardness detection point, the ground hardness detection component is started for detection, and when the detected ground hardness is abnormal, the abnormal point is marked by the marking component and electronically recorded, when the detection vehicle body moves to the soil column sampling point, the ground is vertically sampled by the soil depth sampling component, and then the detection vehicle body is continued to move, and the sampled soil column is moved to the soil column density detection component for density detection, and electronic recording is performed at the same time, after the entire ground to be detected is completely detected, the land consolidation engineering detection device is recovered and data is recovered, and this scheme enables multiple detection items to be completed and recorded by one device, which is more convenient.

[0010] Optionally, the flatness detection component includes a detection support rod evenly arranged along the width direction of the lower end of the detection vehicle body and rotatably set at the lower end of the detection vehicle body, a detection wheel rotatably connected to one end of the rotation axis of the detection support rod and abutting against the ground for rolling, and a fluctuation detection frame sleeved on the middle part of the detection support rod and arranged vertically, a fluctuation hole is formed in the middle part of the fluctuation detection frame for the detection support rod to rotate within a certain range, and the rotation axis of the detection wheel is horizontally perpendicular to the moving direction of the detection vehicle body.

[0011] When the flatness of the ground is detected by the flatness detection component, the detection wheel abuts against the ground, and as the detection vehicle moves, the detection wheel rotates, and the detection wheel rises and falls with the rise and fall of the ground, thereby driving the detection support rod to rotate slightly. The rotation amplitude of the detection support rod is small, and the middle part of the detection support rod will swing up and down in the fluctuation hole, indicating that the ground is relatively flat. When the rotation amplitude of the detection support rod is large, the middle part of the detection support rod will touch the fluctuation detection frame. At this time, the ground detection at this location fails. This solution enables the detection of ground flatness to be carried out in real time, which is more convenient.

[0012] Optionally, an adjustment cylinder for driving the fluctuation detection frame to move vertically is provided at the lower end of the detection vehicle body on the upper side of each fluctuation detection frame, and the detection wheel is located at an end of the detection support rod away from the moving direction of the detection vehicle body.

[0013] An adjusting cylinder is arranged at the lower end of the detection vehicle body, and the fluctuation detection frame is driven to move vertically by the adjusting cylinder, so that when the ground flatness is not detected, the fluctuation detection frame can be driven to move vertically upward by the adjusting cylinder, thereby driving the detection support rod to rotate, so that the detection wheel is separated from the ground, thereby facilitating the overall movement of the detection device. At the same time, the height of the fluctuation detection frame can be adjusted according to the situation to adapt to different needs, which is more convenient.

[0014] Optionally, the ground hardness detection component includes an upper rod vertically slidably connected to the lower end of the detection vehicle body, a compression spring vertically arranged at the lower end of the upper rod, a lower rod vertically arranged at the lower end of the compression spring, a pressure wheel rotatably arranged at the lower end of the lower rod and abutting against the ground, and a camera recorder arranged on one side of the upper rod for obliquely photographing the amount of ground deformation squeezed by the pressure wheel.

[0015] When testing the hardness of the ground, the upper rod is lowered vertically until the pressure wheel contacts the ground, and then the upper rod is continued to be lowered to compress the compression spring. At this time, the testing vehicle body is moved to make the compression spring bend and continue to apply a certain downward pressure to the pressure wheel. The pressure wheel will produce indentations on the ground as it rolls, and the indentations are recorded by a video recorder to analyze the hardness of the ground. This solution makes the detection of the hardness of the ground more convenient.

[0016] Optionally, the soil depth sampling assembly includes a sampling drill pipe, a sampling motor that drives the sampling drill pipe to rotate, a sampling cylinder that drives the sampling motor and the sampling drill pipe to move vertically together, and a moving motor that drives the sampling cylinder, the sampling motor and the sampling drill pipe to rotate synchronously, and the end of the sampling drill pipe away from the sampling motor is provided with drilling teeth that drill into the soil as it rotates.

[0017] When sampling soil columns through the soil depth sampling assembly, the mobile motor drives the sampling cylinder, the sampling motor and the sampling drill pipe to rotate synchronously until the sampling drill pipe is vertically aligned with the ground. Then the sampling cylinder drives the sampling motor and the sampling drill pipe to move downward synchronously. When the drilling teeth at the lower end of the sampling drill pipe abut the ground, the sampling motor is driven to rotate the sampling drill pipe and drill vertically into the ground driven by the drilling teeth until the moving depth is reached. Then the sampling drill pipe is moved upward. At this time, the soil column will be left in the sampling drill pipe. Finally, the mobile motor drives the sampling drill pipe to move to the soil column density detection assembly for density detection. This solution makes sampling of soil columns more convenient.

[0018] Optionally, a thumb cylinder is provided at the end of the output shaft of the sampling motor, and the sampling drill pipe comprises two half-tube drill pipes assembled and abutted together, and the two halves of the half-tube drill pipes are respectively fixed to the clamping claws of the thumb cylinder.

[0019] The sampling drill pipe is provided with two half-tube drill pipes, and the two half-tube drill pipes are controlled to open and buckle by a thumb cylinder. When sampling a soil column, the two half-tube drill pipes are buckled together. When the sampling is completed and the soil column is ready to be released for hardness testing, the two half-tube drill pipes are separated by the thumb cylinder to make the soil column fall out. This solution makes it more convenient to drop out the soil column.

[0020] Optionally, the soil column density detection assembly includes a receiving arc groove horizontally arranged at the upper end of the detection vehicle body and receiving the soil column, a plurality of cutting heads arranged at the upper end of the detection vehicle body and cutting the soil column at even intervals, and a weighing clamp arranged at the upper end of the detection vehicle body and clamping the cut soil column and measuring the weight.

[0021] The fallen soil column falls directly into the receiving arc groove, and then the soil column is evenly cut by the cutting head. Each soil column is clamped and weighed by the weighing claws to obtain the weight of soil columns of the same size at different depths. Finally, the density of soil at different depths is obtained. This solution makes the detection of soil density at different depths more convenient.

[0022] Optionally, the soil column density detection assembly also includes a lifting frame vertically slidably arranged on the upper end of the detection vehicle body and a rotating long frame horizontally connected to the lifting frame, a plurality of cutting heads are fixed to one side end of the rotating long frame, and a plurality of weighing clamps are fixed to the other side end of the rotating long frame.

[0023] When testing the density of the soil column, first raise the rotating long frame vertically so that the soil column can be smoothly placed in the receiving arc groove, then move down and rotate the rotating long frame so that the cutting head is aligned with the soil column, and then continue to move the rotating long frame to evenly cut the soil column. After cutting, rotate the rotating long frame again so that the weighing clamp is aligned with the soil column, and finally clamp and measure the weight of the soil column with the weighing clamp. This solution makes it more convenient to cut and weigh the soil column at the same position.

[0024] Optionally, the marking component includes a plurality of inkjet nozzles, and the plurality of inkjet nozzles are evenly spaced and distributed on two side end surfaces of the detection vehicle body that are perpendicular to each other, and the inkjet ends of the inkjet nozzles are vertically downward.

[0025] The marking component is set to multiple inkjet nozzles, and the inkjet nozzles are set to two groups perpendicular to each other. When the ground flatness detection result is abnormal, each of the two groups of inkjet nozzles sprays ink onto the ground, thereby forming a plane coordinate system, that is, the intersection of the lines connecting two ink dots perpendicular to each other is the flatness detection abnormality point. When the ground hardness is abnormal, only a single inkjet nozzle in a group of inkjet nozzles is needed to spray ink onto the ground. At this time, the ground hardness near the ink dot is marked as abnormal. This solution makes it more convenient to mark and record abnormal ground flatness and hardness.

[0026] In a second aspect, an embodiment of the present invention provides a method for detecting a land reclamation project, including: step one, moving a detection vehicle to the ground to be detected, planning a detection path and ground hardness detection points and soil column sampling points, and then moving the detection vehicle along the planned path; step two, starting a ground flatness detection component while moving, the ground flatness detection component continuously detecting the surface flatness as the detection vehicle moves, and when the detection is abnormal, marking the abnormal ground through a marking component and electronically recording it; step three, when the detection vehicle moves to the ground hardness detection point, starting the ground hardness detection component for detection, and when the detected ground hardness is abnormal, marking the abnormal point through a marking component and electronically recording it; step four, when the detection vehicle moves to the soil column sampling point, vertically sampling the ground through a soil depth sampling component, and then continuing to move the detection vehicle; step five, moving the sampled soil column to the soil column density detection component for density detection, and electronically recording it at the same time; step six, after the entire ground to be detected is completely detected, the land reclamation project detection device is recovered and data is recovered.

[0027] Using this detection method to detect land improvement projects makes the entire detection process more convenient and faster.

[0028] (III) Beneficial effects

[0029] The beneficial effects of the present invention are as follows: when the land consolidation project detection device and detection method of the present invention are used to detect the land consolidation project, the detection vehicle body is moved to the ground to be detected, the detection path and the ground hardness detection points and soil column sampling points are planned, and then the detection vehicle body is moved according to the planned path, and the ground flatness detection component is started while moving. The ground flatness detection component continuously detects the surface flatness as the detection vehicle body moves. When an abnormality is detected, the abnormal ground is marked by the marking component and electronically recorded. When the detection vehicle body moves to the ground hardness detection point, Start the ground hardness detection component for detection. When the detected ground hardness is abnormal, mark the abnormal point through the marking component and make electronic records. When the detection vehicle moves to the soil column sampling point, the ground is vertically sampled through the soil depth sampling component. Then continue to move the detection vehicle, and the sampled soil column moves to the soil column density detection component for density detection, and electronic records are made at the same time. After the entire ground to be tested is completely tested, the land reclamation project detection device is recovered and data is recovered. This solution makes it more convenient to complete the detection and record of multiple detection items through one device. BRIEF DESCRIPTION OF THE DRAWINGS

The ground flatness detection component continuously detects the surface flatness as the detection vehicle body moves. When the detection is abnormal, the abnormal ground is marked by the marking component and electronically recorded. When the detection vehicle body moves to the ground hardness detection point, the ground hardness detection component is started for detection. When the detected ground hardness is abnormal, the abnormal point is marked by the marking component and electronically recorded. When the detection vehicle body moves to the soil column sampling point, the ground is vertically sampled by the soil depth sampling component, and then the detection vehicle body is continued to move. The sampled soil column is moved to the soil column density detection component for density detection, and electronic recording is performed at the same time. After the entire ground to be detected is completely detected, the land consolidation engineering detection device is recovered and data is recovered. This solution enables multiple detection items to be fully detected and recorded by one device, which is more convenient.

[0037] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0038] Reference Figure 1 and Figure 2 A land consolidation engineering detection device comprises a detection vehicle body 1 moving along the consolidation ground, a ground flatness detection component 2 arranged at the lower end of the detection vehicle body 1 and horizontally arranged along the moving direction of the detection vehicle body 1, a marking component 3 arranged at the side end of the detection vehicle body 1 and marking the ground, a ground hardness detection component 4 arranged at the lower end of the detection vehicle body 1 and detecting the ground hardness at the moving interval of the detection vehicle body 1, a soil depth sampling component 5 arranged at the side end of the detection vehicle body 1 and taking soil from the ground to be detected in an array as the detection vehicle body 1 moves, and a soil column density detection component 6 arranged at the upper end of the detection vehicle body 1 and receiving and detecting the soil column taken out by the soil depth sampling component 5.

[0039] The detection vehicle body 1 has a built-in microcomputer, through which the moving path of the detection vehicle body 1 and the working conditions of each component can be recorded and data can be generated.

[0040] The ground flatness detection assembly 2 includes a detection support rod 21 which is evenly spaced along the width direction of the lower end of the detection vehicle body 1 and is rotatably arranged at the lower end of the detection vehicle body 1 through a rotating shaft, a detection wheel 22 which is rotatably connected to one end of the rotation axis of the detection support rod 21 through a bearing and rolls against the ground, and a fluctuation detection frame 23 which is sleeved on the middle part of the detection support rod 21 and arranged vertically. A fluctuation hole 231 is formed in the middle part of the fluctuation detection frame 23 for the detection support rod 21 to rotate within a certain range. The rotation axis of the detection wheel 22 is horizontally perpendicular to the moving direction of the detection vehicle body 1. An adjusting cylinder 24 for driving the fluctuation detection frame 23 to move vertically is vertically fixed to the upper side of each fluctuation detection frame 23 at the lower end of the detection vehicle body 1 through bolts. The detection wheel 22 is located at one end of the detection support rod 21 away from the moving direction of the detection vehicle body 1. A pressure detection trigger is built into the adjusting cylinder 24. When the fluctuation detection frame 23 is subjected to a large squeezing force from the detection support rod 21, the force will be transmitted to the pressure detection trigger inside the adjusting cylinder 24, thereby completing the detection.

[0041] The ground hardness detection component 4 includes an upper rod 41 which is vertically slidably connected to the lower end of the detection vehicle body 1 by a cylinder, a compression spring 42 which is vertically fixed to the lower end of the upper rod 41 by bolts, a lower rod 43 which is vertically fixed to the lower end of the compression spring 42 by bolts, a pressure wheel 44 which is rotatably arranged at the lower end of the lower rod 43 through a bearing and abuts against the ground, and a video recorder 45 which is fixed to one side of the upper rod 41 by bolts and obliquely records the amount of ground deformation squeezed by the pressure wheel 44.

[0042] See also Figure 1 and Figure 3 The soil depth sampling assembly 5 includes a sampling drill pipe 51, a sampling motor 52 for driving the sampling drill pipe 51 to rotate, a sampling cylinder 53 for driving the sampling motor 52 and the sampling drill pipe 51 to move vertically together, and a moving motor 54 for driving the sampling cylinder 53, the sampling motor 52 and the sampling drill pipe 51 to rotate synchronously. The end of the sampling drill pipe 51 away from the sampling motor 52 is integrally provided with a drilling tooth 55 that drills into the soil as it rotates.

[0043] The output shaft end of the sampling motor 52 is fixed with a thumb cylinder 56 by bolts. The sampling drill pipe 51 includes two half-tube drill pipes assembled and abutted together. The two half-tube drill pipes are respectively welded and fixed to the clamping claws of the thumb cylinder 56.

[0044] The soil column density detection assembly 6 includes a receiving arc groove 61 horizontally fixed to the upper end of the detection vehicle body 1 and receiving the soil column, a lifting frame 62 vertically and slidingly arranged on the upper end of the detection vehicle body 1 driven by a cylinder, a rotating long frame 63 connected to the lifting frame 62 driven by a motor to rotate horizontally, a plurality of cutting heads 64 for cutting the soil column fixed to the side end of the rotating long frame 63 by bolts evenly spaced along the length direction of the rotating long frame 63, and a weighing clamp 65 evenly spaced and fixed to the other side end of the rotating long frame 63 by bolts. The weighing clamp 65 includes a small weighing scale and a clamping cylinder fixed on the small weighing scale, and then the cut soil column is clamped and the weight is measured by the weighing clamp 65.

[0045] The marking assembly 3 includes a plurality of inkjet heads 31 , which are evenly fixed to the two side end surfaces of the detection vehicle body 1 which are perpendicular to each other by bolts, and the inkjet ends of the inkjet heads 31 are vertically downward.

[0046] When the ground is inspected by the land reclamation engineering inspection device, step one is to move the inspection vehicle body 1 to the ground to be inspected, plan the inspection path and the ground hardness inspection points and soil column sampling points, and then move the inspection vehicle body 1 according to the planned path; step two, the inspection wheel 22 is in contact with the ground, and as the inspection vehicle body 1 moves, the inspection wheel 22 rotates, and the inspection wheel 22 fluctuates up and down with the ups and downs of the ground, thereby driving the inspection support rod 21 to rotate slightly. The rotation amplitude of the inspection support rod 21 is small, and the middle part of the inspection support rod 21 will swing up and down in the fluctuation hole 231, indicating that the ground is relatively flat. When the rotation amplitude of the inspection support rod 21 is large, the middle part of the inspection support rod 21 will touch the fluctuation detection frame 23. At this time, the inspection support rod 21 is relatively flat. The ground detection is unqualified. When the detection is abnormal, the abnormal ground is marked by the marking component 3. One of the two groups of inkjet nozzles 31 sprays ink to the ground to form a plane coordinate system, that is, the intersection of the two ink dots perpendicular to each other is the abnormal point of flatness detection, and it is electronically recorded; Step three, when the detection vehicle body 1 moves to the ground hardness detection point, the ground hardness detection component 4 is started for detection, and the upper rod 41 is vertically lowered until the pressure wheel 44 abuts against the ground, and then the upper rod 41 continues to slide down, so that the compression spring 42 is compressed. At this time, the detection vehicle body 1 is moved, so that the compression spring 42 is in a bent state and continuously applies a certain downward pressure to the pressure wheel 44. At this time, the pressure wheel 44 will produce an indentation on the ground as it rolls, and then through the camera recorder 4 5 records the indentation, so as to analyze the hardness of the ground. When the hardness of the detected ground is abnormal, the abnormal point is marked by the marking component 3. Only a single inkjet nozzle 31 in a group of inkjet is needed to spray ink on the ground. At this time, the ground hardness near the ink point is marked as abnormal and electronically recorded. Step 4: When the detection vehicle body 1 moves to the soil column sampling point, the ground is vertically sampled by the soil depth sampling component 5. The sampling cylinder 53, the sampling motor 52 and the sampling drill pipe 51 are driven by the moving motor 54 to rotate synchronously until the sampling drill pipe 51 is vertically aligned with the ground. Then the sampling cylinder 53 drives the sampling motor 52 and the sampling drill pipe 51 to move downward synchronously. When the drilling teeth 55 at the lower end of the sampling drill pipe 51 abut against the ground, the sampling is driven The motor 52 makes the sampling drill pipe 51 rotate, and drills vertically into the ground driven by the soil drilling teeth 55 until the moving depth is reached, and then the sampling drill pipe 51 is moved upward, at which time the soil column will be left in the sampling drill pipe 51, and then the detection vehicle body 1 is continued to be moved; step five, the two halves of the half-tube drill pipe are separated by the thumb cylinder 56, so that the soil column falls into the receiving arc groove 61, and then the density is tested by the soil column density detection component 6, and the rotating long frame 63 is moved downward and rotated so that the cutting head 64 is aligned with the soil column, and then the rotating long frame 63 is continued to be moved, so as to evenly cut the soil column, and after the cutting is completed, the rotating long frame 63 is rotated again so that the weight measuring jaws 65 are aligned with the soil column, and finally the weight of the soil column is clamped and measured by the weight measuring jaws 65, and electronically recorded at the same time;Step 6: After the entire ground to be inspected is completely inspected, the land improvement engineering inspection device is recovered and data is recovered. ;
