Description

Technical Field

[0001] The present invention relates to the technical field of highway engineering, and particularly to a subgrade reinforcement and protection structure and an intelligent detection device for its diseases. Background Art

[0002] The subgrade is a soil and stone structure that is easily damaged by various disasters such as floods, debris flows, collapses, and earthquakes. In order to ensure the stability of the subgrade, it is generally necessary to carry out reinforcement and protection treatment on the subgrade. In the prior art, the reinforcement and protection of the subgrade generally adopt the method of concrete pouring; however, the reinforcement and protection method of concrete pouring has a long construction period and low efficiency, and requires a large amount of labor and material costs.

[0003] Moreover, after the road is built, it is necessary to detect the diseases of the subgrade, and timely discover the precursors of danger according to the detection results. However, for the existing road disease detection devices, in order to ensure the detection effect of the detection main body, it is necessary to place the detection equipment as close to the road surface as possible. When moving the detection equipment, some stones on the road surface are likely to scratch the detection equipment, thereby reducing the service life of the detection equipment and being unfavorable for ensuring the safe use of the detection equipment. Summary of the Invention

[0004] The purpose of the present invention is to provide a subgrade reinforcement and protection structure and an intelligent detection device for its diseases, so as to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A subgrade reinforcement and protection structure includes a plurality of retaining walls located on both sides of the subgrade. Two adjacent retaining walls are spliced together. A through groove is opened at the top of the retaining wall along the length direction. An insertion bar adapted to the through groove is provided at the bottom of the retaining wall. A plurality of anchor rods are provided at both the left and right ends of the insertion bar. Anchor holes adapted to the anchor rods are opened on the through groove. A plurality of insertion holes are opened on the through groove.

The fixing frame is detachably installed at the rear end of the top of the retaining wall along the length direction. The blocking component includes a rotating shaft, a baffle plate, and a pushing plate. The rotating shaft is rotatably arranged at the front end of the fixing frame. The pushing plate is arranged at the front end of the rotating shaft, and a torsion spring is connected between the pushing plate and the fixing frame. The baffle plate is arranged at the top of the pushing plate, and a gap is left between every two adjacent baffle plates; when the pushing plate is pushed by an external force, it will drive the baffle plate to rotate synchronously; when the external force is removed, the baffle plate will automatically reset to the initial position under the torque generated by the torsion spring.

[0006] Further, a card slot is provided at the left end of the retaining wall panel, and a card block adapted to the card slot is provided at the right end; on both the left and right sides of the top end of the rear end face of the retaining wall panel, support seats are provided, and on both the left and right sides of the bottom end of the rear end face of the retaining wall panel, fixing seats are provided. Fixing holes are provided in the fixing seats, threaded holes corresponding to the fixing holes are provided at the top ends of the support seats, and the support seats communicate with the side wall of the through groove.

[0007] Further, a number of arc-shaped plates are uniformly distributed from top to bottom on both the left and right sides of the front end face of the retaining wall panel, and the arc-shaped plates on the left and right sides are arranged in reverse.

[0008] Further, a number of irrigation holes corresponding to the through holes are provided in the upper part of the rear end face of the retaining wall panel, and the irrigation holes communicate with the corresponding through holes; a green plant trough is detachably installed in the middle of the rear end face of the retaining wall panel. The green plant trough is located below the irrigation holes, and a through opening is provided in the middle of the front end face of the retaining wall panel, and the through opening extends through and communicates with the front end wall of the green plant trough.

[0009] Further, when the torsion spring is in the initial state, the push plate is inclined at a certain angle to the through groove, while the rear end of the baffle is parallel to the length direction of the through groove.

[0010] The present invention also provides a disease intelligent detection device, which is applied to the above-mentioned subgrade reinforcement and protection structure, and includes a vehicle body, a cleaning device and a main detection device. The vehicle body is used to drive the cleaning device and the main detection device to move along the subgrade. The main detection device is connected behind the cleaning device. The cleaning device includes a frame, a collecting hopper and a cleaning roller. The collecting hopper is liftably installed at the bottom end of the frame. A feed inlet is provided on the front end face of the collecting hopper. The cleaning roller is rotatably arranged at the feed inlet and is driven to rotate by a motor. Cleaning mechanisms adapted to the through grooves are detachably provided at both the left and right ends of the collecting hopper; The cleaning mechanism includes a shovel plate, a feeding box and a pushing frame. The feeding box is installed at the front end of the collecting hopper, and a discharge port is provided at the rear end of the feeding box. The discharge port communicates with the collecting hopper. The shovel plate is installed at the bottom of the front end of the feeding box. An inlet is provided at the front end of the feeding box. The pushing frame is installed on the shovel plate. The front end of the pushing frame is a slope adapted to the push plate. When the pushing frame moves forward, its slope will push the front push plate to generate a rotating action.

[0011] Further, bases are provided at both the left and right ends of the collecting hopper. The feeding box is horizontally slidably assembled at the front end of the collecting hopper. A number of sliding rods are provided on the side wall of the feeding box. The sliding rods slidably penetrate through the bases, and springs are sleeved on the surfaces of the sliding rods.

[0013] Furthermore, the main body of the detection device is an existing subgrade detection device, such as: Rayleigh surface wave exploration equipment, three-dimensional laser scanning vehicle, etc.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The retaining wall board of the present invention realizes rapid horizontal and vertical splicing through components such as clamping grooves, clamping blocks, inserting strips, and through grooves to form a three-dimensional grid structure (for example, the inserting rod and the inserting hole provide vertical limit, and the anchor rod and the anchor hole achieve horizontal locking), reducing the formwork erection and curing time required for traditional concrete pouring. At the same time, the bolt connection between the support seat and the fixed seat and the setting of the arc plate enhance the anti-overturning ability, simplify the on-site installation process, and do not require large machinery, saving time and effort.

[0015] 2. Under normal conditions, the blocking mechanism of the present invention allows rainwater and small debris to be discharged through intervals. When silt accumulates, a special cleaning tool can automatically push the push plate, drive the baffle to rotate 90°, expose the through groove and then quickly scrape it. After the external force is removed, the torsion spring automatically resets the baffle within 1 - 3 seconds, eliminating the need for manual removal of components and solving the cumbersome problem of frequent disassembly and assembly of traditional filter grilles.

[0016] 3. The disease detection device of the present invention integrates a cleaning roller and an aggregate hopper, which sweeps the road surface of stones and garbage before detection to prevent the main body of the detection device (such as a camera or a sensor) from being scratched and extends the service life of the equipment. At the same time, the cleaning mechanism synchronously processes the silt in the through groove without manual cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1 to 5 shown, a roadbed reinforcement and protection structure includes a plurality of retaining wall panels 1 located on both sides of the roadbed. Two adjacent retaining wall panels 1 are spliced with each other. A through groove 2 is opened at the top end of the retaining wall panel 1 along the length direction. An inserting strip 3 adapted to the through groove 2 is provided at the bottom end of the retaining wall panel 1. A plurality of anchor rods 4 are provided at both the left and right ends of the inserting strip 3. An anchor hole 5 adapted to the anchor rod 4 is opened on the through groove 2. A plurality of inserting holes 6 are opened on the through groove 2. A plurality of inserting rods 7 corresponding to the inserting holes 6 are provided at the bottom end of the inserting strip 3. And a through hole 8 is provided at the bottom of the inserting hole 6, and the through hole 8 extends through to the bottom end of the inserting rod 7; A blocking mechanism 9 is detachably installed at the top end of the retaining wall panel 1. The blocking mechanism 9 includes a fixing frame 10 and a plurality of blocking components arranged at equal intervals on the fixing frame 10. The fixing frame 10 is detachably installed at the rear end of the top of the retaining wall panel 1 along the length direction. The blocking component includes a rotating shaft 11, a baffle plate 12 and a pushing plate 13. The rotating shaft 11 is rotatably arranged at the front end of the fixing frame 10. The pushing plate 13 is arranged at the front end of the rotating shaft 11. And a torsion spring is connected between the pushing plate 13 and the fixing frame 10. The baffle plate 12 is arranged at the top end of the pushing plate 13, and there is an interval between every two adjacent baffle plates 12; When the pushing plate 13 is pushed by an external force, it will drive the baffle plate 12 to rotate synchronously; When the external force is removed, the baffle plate 12 will automatically reset to the initial position under the torque generated by the torsion spring; When the torsion spring is in the initial state, the pushing plate 13 is inclined at a certain angle to the through groove 2, and the rear end of the baffle plate 12 is parallel to the length direction of the through groove 2; The baffle 12 is parallel to the through slot 2 under normal conditions (as shown in the attached Figure 4 Schematic diagram), a certain gap is retained between adjacent baffles 12. This gap is for the convenience of the rotation of the baffles 12 on the one hand, and on the other hand, it can allow rainwater and debris to pass through, but effectively intercept large particles of stones, leaves and branches and other impurities, thereby preventing impurities from entering the through groove 2 and clogging the through hole 8; After a period of time, when a certain amount of sediment accumulates in the through groove 2, the staff can use a special cleaning tool (such as a T-shaped push rod with a roller) to move along the through groove 2. The front end of the tool pushes the push plate 13, driving the rotating shaft 11 to overcome the torsion spring torque, and the baffle 12 rotates 90° (as shown in the attached figure). Figure 4 Schematic diagram), thereby completely exposing the through groove 2, at this time, a tool can be used to synchronously scrape off the silt or push the silt forward to gather. After the tool is removed, the torsion spring automatically resets the baffle 12 within 1-3 seconds without manual intervention, or the cleaning mechanism described below can be removed and used separately; compared with the traditional ditch that uses a filter grille for cleaning, it is necessary to remove the grille and then reinstall it after cleaning, and the operation steps are too complicated and cumbersome. This embodiment can achieve disassembly-free cleaning and achieve efficient operation.

[0021] In this embodiment, a card slot 14 is provided at the left end of the baffle plate 1, and a card block 15 adapted to the card slot 14 is provided at the right end; support seats 16 are provided on both sides of the top of the rear end surface of the baffle plate 1, and fixing seats 17 are provided on both sides of the bottom of the rear end surface of the baffle plate 1. A fixing hole 18 is provided on the fixing seat 17, and a threaded hole 19 corresponding to the fixing hole 18 is provided at the top of the support seat 16. The support seat 16 is connected to the side wall of the through groove 2; When assembling the retaining wall panel 1, adjacent retaining wall panels 1 are transversely engaged through the card slots 14 and the card blocks 15, and the bottom end strips 3 are longitudinally engaged with the top end slots 2 to form a three-dimensional grid structure; the insertion rods 7 and the insertion holes 6 system provide vertical limitation, and the anchor rods 4 and the anchor holes 5 are locked through transverse penetration to achieve three-dimensional mechanical transmission and effectively disperse the roadbed load. The support seat 16 and the fixing seat 17 are connected by bolts (through the fixing holes 18 and the threaded holes 19) to form an auxiliary fixing point, thereby improving the overall anti-overturning ability; and the insertion strips 3, anchor rods 4 and insertion rods 7 of the bottom retaining wall panel 1 are directly inserted into the ground, and the fixing seat 17 is fixed to the ground by anchor nails, so that it is buried deep into the foundation to form a shear bite surface, thereby ensuring the stability of the base retaining wall panel 1.

[0022] In this embodiment, a plurality of arc-shaped plates 20 are evenly distributed on the left and right sides of the front end face of the retaining wall panel 1 from top to bottom, and the arc-shaped plates 20 on the left and right sides are arranged in reverse; during installation, the arc-shaped plates 20 are inserted into the side wall of the roadbed, so that the contact area with the soil body is increased, thereby increasing the friction force between the two; the friction force is an important factor for the retaining wall panel 1 to resist the lateral pressure of the soil body. The greater the friction force, the better the stability of the retaining wall panel 1, and it can more effectively resist the lateral thrust of the soil body, preventing the retaining wall panel 1 from displacing or overturning, and this structure can exert a certain lateral restraint force on the pit wall. When the soil body is restricted by the arc-shaped plate 20, its lateral deformation will be restricted, thereby reducing the displacement and settlement of the soil body. In this embodiment, a plurality of irrigation holes 21 corresponding to the through holes 8 are provided in the upper part of the rear end face of the retaining wall panel 1, and the irrigation holes 21 communicate with the corresponding through holes 8; a green plant trough 22 is detachably installed in the middle of the rear end face of the retaining wall panel 1, and the green plant trough 22 is located below the irrigation holes 21; and a through opening 23 is provided in the middle of the front end face of the retaining wall panel 1, and the through opening 23 extends through and communicates with the front end wall of the green plant trough 22. During rain, the rainwater on the roadbed will flow into the through groove 2, and a part of the water in the through groove 2 is vertically injected into the soil layer 1 m deep below the ground through the through holes 8 and the inserting rods 7, avoiding surface erosion and significantly improving the shear strength of the soil body; another part of the water is injected out through the irrigation holes 21, thereby performing drip irrigation on the green plant trough 22. Through hole 8 (main infiltration path): with a diameter of 30 - 50 mm, preferentially infiltrating 60 - 70% of the rainwater into the deep soil (below 1 m) to maintain the stable moisture content of the roadbed (15 - 18%); irrigation hole 21 (lateral drainage path): with a diameter of 10 - 15 mm, discharging 30 - 40% of the excessive rainwater through the side of the retaining wall panel 1 to prevent the shallow soil from being saturated (>25%). The roots of the plants in the green plant trough 22 can take root into the side wall of the roadbed through the through opening 23, thereby forming a composite anchoring layer with the retaining wall panel 1 to enhance the shear strength of the soil body; and the transpiration of the plants can adjust the soil humidity and reduce the risks of frost heaving and landslides.

[0023] Please refer to Figures 6 - 8 As shown, this embodiment also provides a disease intelligent detection device, which is applied to the above-mentioned roadbed reinforcement and protection structure, and includes a vehicle body, a cleaning device and a main detection device. The vehicle body is used to drive the cleaning device and the main detection device to move along the roadbed. The main detection device is connected behind the cleaning device. The cleaning device includes a frame 24, a collecting hopper 25 and a cleaning roller 26. The collecting hopper 25 is liftably installed at the bottom end of the frame 24. An inlet 27 is provided on the front end face of the collecting hopper 25. The cleaning roller 26 is rotatably arranged at the feed inlet 32 and is driven to rotate by a motor. Cleaning mechanisms adapted to the through grooves 2 are detachably arranged at the left and right ends of the collecting hopper 25. The cleaning mechanism includes a scraping plate 29, a feeding box 30, and a pushing frame 31. The feeding box 30 is installed at the front end of the aggregate hopper 25, and a discharge port is provided at the rear end of the feeding box 30. The discharge port communicates with the aggregate hopper 25. The scraping plate 29 is installed at the bottom of the front end of the feeding box 30. An inlet 32 is provided at the front end of the feeding box 30. The pushing frame 31 is installed on the scraping plate 29. The front end of the pushing frame 31 is an inclined surface adapted to the push plate 13. When the pushing frame 31 moves forward, its inclined surface will push the front push plate 13 to produce a rotational movement.

[0024] The working principle of this device is as follows: When the roadbed needs to be detected for diseases after the road is constructed, the staff drives the vehicle body to drive the cleaning device and the main body of the detection device at the rear to move on the road surface. At this time, the motor is started, and the cleaning roller 26 is driven by the motor to rotate continuously, so as to clean the road surface, sweep the garbage and stones into the aggregate hopper 25, keep the road surface clean, and the main body of the detection device at the rear detects the diseases of the roadbed of the cleaned road surface; when the cleaning device moves on the road surface, the cleaning mechanisms on both sides are placed in the through grooves 2 on both sides to clean the sand and stones that enter the through grooves 2 during the construction process. When the cleaning mechanism moves along the through groove 2 at a speed of 0.5 - 1.2 m / s, the pushing frame 31 contacts the baffle 12 and the push plate 13, and the inclined surface decomposes the horizontal thrust into a lateral component force, overcoming the torque of the torsion spring, and driving the rotating shaft 11 to rotate 90°, so as to ensure that the scraping plate 29 will not be stuck due to the blockage of the baffle 12. When the scraping plate 29 advances in the through groove 2, it forcibly lifts the loose silt off the bottom of the groove, and the hard fragments (such as stones) are shoveled up by the cutting edge, and the garbage naturally slides into the inlet 32 of the feeding box 30. When the garbage accumulates to a certain height in the feeding box 30, with the continuous pushing of new garbage, the upper-layer garbage falls from the discharge port into the aggregate hopper 25. The two bottom sides of the aggregate hopper 25 are inclined at 70°. After the garbage falls in, it slides along the hopper wall to the central area, avoiding the formation of dead corners due to accumulation in the corners.

[0025] In this embodiment, pedestals 33 are provided at both the left and right ends of the aggregate hopper 25. The feeding box 30 is horizontally slidably assembled at the front end of the aggregate hopper 25. A plurality of sliding rods 34 are provided on the side wall of the feeding box 30. The sliding rods 34 slidably pass through the pedestals 33, and a spring 35 is sleeved on the surface of the sliding rods 34. The spring 35 is connected between the pedestal 33 and the feeding box 30; the feeding box 30 realizes a displacement compensation of ±10 cm through the sliding rods 34 and the spring 35 to adapt to the splicing error of the retaining wall panel 1 or the error of non-parallelism on both sides of the road.

[0026] In this embodiment, a plurality of telescopic cylinders 36 are fixed on the frame 24. The piston rod of the telescopic cylinder 36 is connected to the aggregate hopper 25. A plurality of wheel seats 37 are arranged at the rear end of the frame 24. A traveling wheel 38 is rotatably connected to the wheel seat 37. A plurality of rollers are rotatably arranged at the bottom of the aggregate hopper 25. The aggregate hopper 25 and the cleaning mechanism are driven to lift by the telescopic cylinder 36. On the one hand, it ensures that the scraping plate 29 always maintains the best fitting distance from the through groove 2 at the top of the retaining wall 1. On the other hand, when it is detected that the vehicle body passes through the roadbed joint or local uplift, the telescopic cylinder 36 retracts the aggregate hopper 25 in real time to avoid rigid collision.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
