Description

Technical Field

[0001] The invention relates to the technical field of fill slope, in particular to a slope surface flatness control device. Background Art

[0002] Fill slopes are widely used in highways, railways, airports, power and other industries. In order to achieve the required stable slope during construction, the usual construction method is to overfill a certain area, and then brush the slope to locate and excavate the overfilled part after the slope is fully compacted. Although reinforced soil slopes do not need to be overfilled, the slope line shape mostly needs to be manually leveled during construction.

[0003] In the existing process of filling the slope, the slope is overfilled in a certain area, and the overfilled part is removed by brushing after the slope surface is compacted. Although this can solve the compaction problem near the slope surface, it will greatly increase the ineffective filling and excavation operations, low construction efficiency, and greatly increase the construction cost. Although there is no need for overfilling during the construction of reinforced soil slopes, the flatness of the slope line needs to be manually trimmed with shovels or wooden boards, which has low work efficiency and difficult line control. Since the slope surface has no support, large-scale machinery cannot be used for compaction, which makes the slope surface prone to uneven settlement in the later stage, affecting the overall flatness of the slope surface. Therefore, we propose a slope flatness control device. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a slope flatness control device, which solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a slope flatness control device, including a base plate, a support plate is fixedly installed on the top left side of the base plate by bolts, and the support plate is L-shaped, the right side of the base plate is inclined, a pull ring is fixedly installed on the left side of the base plate by bolts, an angle dial is fixed on the front side of the base plate, a force angle plate is hinged on the outside of the middle side of the base plate, and the force angle plate is located at the angle dial, a positioning line is opened on the front side of the force angle plate, a Y joint is hinged on the side where the force angle plate and the support plate are close to each other, a support screw is fixed on the side where the two Y joints are close to each other, and the two support screws An adjusting threaded cylinder is threadedly connected between the rods, a pressure gauge is fixed to the top of one side of the force angle plate close to the support plate, pressure sensors are threadedly connected at the four corners of the side of the force angle plate away from the support plate, and a pad is threadedly connected at one end of the four pressure sensors away from the support plate. The length of the support screw is changed according to the slope rate of the construction slope, and the support screw pushes the angle of the force angle plate to change. The position of the angle dial corresponding to the positioning line on the force angle plate is the slope of the slope. Then the slope is laid out, and the slope flatness control device is positioned and placed according to the slope lay-out position. A set of slope flatness control devices is placed with a longitudinal spacing of one meter, and the bottom plate is inserted into the slope In the body, a steel membrane is placed on the inner side of the pad (the steel membrane specification is one meter long and two meters wide). According to the reinforcement length, the geogrid is cut. The length of the geogrid is the reinforcement length + the vertical wrapping length. The first layer of geogrid is laid: after the vertical wrapping length of the geogrid is reserved, it is positioned and placed behind the steel membrane and fixed with U-shaped nails. The laid geogrid is tensioned and fixed with U-shaped nails at the tail end of the geogrid. The adjacent geogrids are overlapped for two meters and fixed with U-shaped nails. The next step is to carry out soil filling construction. The reserved grid on the slope is placed on the other side of the steel membrane. A dump truck or bucket machine is used to unload the material in a vertical dumping manner. The material is gradually unloaded from the back of the steel membrane to the tail end of the geogrid. Then the filling is carried out. The thickness of the layered fill is between thirty centimeters and fifty centimeters. After reaching the layered fill thickness, the fill compaction construction is carried out, first static pressure and then vibration compaction. When the compaction machinery has been compacting for one hour and the pressure gauge reading is the required pressure value, the slope compaction degree has reached the compaction requirement, then the second layer of geogrid is laid, and the geogrid reserved for the first layer is connected to the second layer of geogrid. While tensioning, the geogrid is fixed with U-shaped nails at the end. After the fill height reaches the height of the steel membrane arrangement, the bucket teeth of the excavator bucket are used to pass through the pull ring and slowly pull out the slope a certain distance of ten to twenty centimeters. Remove the steel membrane, and then pull the bottom plate out of the slope. Repeat the above steps until the slope construction is completed.

[0006] According to the above technical scheme, a sliding rod is penetrated and slidably installed on the rear side of the force-bearing angle plate close to the supporting plate, a cross-shaped plate is fixed on the right side of the sliding rod, and a nut is fixed on the front side of the force-bearing angle plate close to the supporting plate. The internal thread of the nut is connected with a threaded rod, and the threaded rod penetrates the force-bearing angle plate, and the right end of the threaded rod is rotatably connected to the left side of the cross-shaped plate. When the steel film is placed on the inner side of the pad, the steel film is located between the force-bearing angle plate and the cross-shaped plate. When the threaded rod is rotated, the threaded rod is acted upon by the thread of the nut and moves to the left side. Under the joint action of the threaded rod and the sliding rod, the threaded rod and the sliding rod pull the cross-shaped plate toward the force-bearing angle plate, and the cross-shaped plate clamps the steel film on the outside of the force-bearing angle plate.

[0007] According to the above technical solution, the outside of the cross-shaped plate is provided with an anti-skid device, and the anti-skid device includes a rubber belt, a plurality of indented grooves, two rollers, two one-way bearings, two friction plates, and two friction wheels. The two rollers are rotatably installed on the top and bottom of the cross-shaped plate respectively, and the rubber belt transmission is connected to the outside of the two rollers. A plurality of indented grooves are evenly and equidistantly arranged on the outside of the rubber belt. The two one-way bearings are respectively fixed on the lower front side and the lower rear side outer wall of the cross-shaped plate. The one-way bearing is used to control the one-way rotation of the lower roller. The two friction wheels are respectively fixed on the front side and the rear side of the lower roller shaft. The two friction plates are respectively fixed on the right front and the right rear of the force angle plate. The top of the friction plate is set as a rough surface, and the outer wall of the friction wheel is set as a rough surface. The top of the friction plate contacts the outer wall of the friction wheel. At the same time, when the cross-shaped plate is close to the force When the angle plate is applied, the cross-plate will drive the rubber belt toward the steel film through two rollers. The rubber belt increases the friction between the cross-plate and the steel film. Several indentations on the surface of the rubber belt further increase the friction of the rubber belt. In the process of the cross-plate approaching the force-bearing angle plate, the cross-plate drives the friction wheel to move through the roller below. Under the action of the friction between the friction wheel and the friction plate, the friction plate drives the friction wheel to rotate, and the friction wheel drives the roller below to rotate. When the two rollers rotate, the two rollers drive the rubber belt to rotate. Each time the cross-plate moves away from the force-bearing angle plate, the cross-plate drives the friction wheel away from the force-bearing angle plate through the roller below. At this time, the roller below is restricted by the one-way bearing and will not rotate. The roller will restrict the friction wheel, so that the friction wheel will not rotate. The friction wheel between the friction plates will slip at this time, and this cycle will repeat. The rubber belt will rotate once each time it is used.

[0008] According to the above technical solution, the anti-slip device also includes two telescopic rods and two slide plates. The sides of the two friction plates that are away from each other are provided with slide grooves. The two slide plates are slidably installed in the slide grooves corresponding to the two friction plates. The two telescopic rods are respectively fixed on the tops of the two slide plates. The sides of the two telescopic rods that are close to each other are respectively rotatably connected to the sides of the two friction wheels that are away from each other. At the same time, during the movement of the friction wheels, the friction wheels drive the slide plates to move along the slide grooves of the friction plates through the telescopic rods. Under the elastic force of the telescopic rods, the telescopic rods will drive the friction wheels to be close to the friction plates.

[0009] According to the above technical scheme, an anti-foreign object device is arranged between the cross-shaped plate and the rubber belt, and the anti-foreign object device includes a plurality of arc blocks, a plurality of knocking rods, two cross bars, two abutment rods, two fixed columns, and two cross plates. A circular groove is opened in the middle of the two rotating rollers, and a plurality of the arc blocks are evenly and equidistantly fixed on the inner walls of the circular grooves corresponding to the two rotating rollers. The two fixed columns are respectively slidably installed on the upper and lower outer walls of the cross-shaped plate. The two cross plates are respectively fixed on the ends of the two fixed columns close to each other, and a spring is arranged between the cross plate and the outer wall of the cross-shaped plate. The two cross bars are respectively fixed on the ends of the two fixed columns away from each other, and the two abutment rods are respectively fixed on the middle part of one side of the cross bar away from the cross plate. The plurality of the knocking rods are evenly and equidistantly The end of the knocking rod away from the cross bar is in contact with the outer wall of the roller. When the roller rotates, the roller drives the arc block to rotate. The arc block pushes the semicircular shape of the knocking rod to drive the knocking rod to move toward the center of the cross-shaped plate. The knocking rod drives the cross bar to move toward the center of the cross-shaped plate. The cross bar drives the fixed column and the cross plate to move. The spring corresponding to the cross plate is stretched. At this time, the knocking rod will move away from the roller. When the arc block no longer pushes the knocking rod, under the action of the spring force corresponding to the cross plate, the cross plate drives the cross bar to reset through the fixed column. The cross bar drives the knocking rod to hit the roller, and the roller vibrates and drives the rubber belt to vibrate.

[0010] According to the above technical solution, the anti-foreign object device also includes an elastic arc plate, which is fixed between two horizontal plates, and the outer wall of the elastic arc plate on the side away from the cross-shaped plate is in contact with the inner wall of the rubber belt. At the same time, when the horizontal bar drives the horizontal plate to move toward the center of the cross-shaped plate through the fixed column, the two horizontal plates will squeeze the elastic arc plate, and the elastic arc plate will bulge and deform in the direction away from the cross-shaped plate. The elastic arc plate pushes the inner wall of the rubber belt to drive one side of the rubber belt to bulge. After one side of the rubber belt bulges, the indentation groove will be deformed.

[0011] The present invention provides a slope flatness control device, which has the following beneficial effects:

[0012] (1) The present invention can synchronously control the slope rate of the slope surface without the need for a traditional angle measuring device by setting the slope surface flatness control device. At the same time, during the soil filling compaction operation, the filler is directly piled behind the steel membrane without taking other protective measures. The compaction machine can directly perform compaction operation near the slope surface. Under the joint action of the steel membrane and the slope surface flatness control device, a flat slope surface is formed after mechanical compaction impact. The soil pressure of the filler near the slope surface behind the force angle plate can be accurately measured by a pressure gauge, thereby accurately controlling the compaction degree of the slope surface. At the same time, the force angle plate, the cross plate, the threaded rod, the nut, and the sliding rod cooperate to drive the cross plate to clamp the steel membrane outside the force angle plate, ensuring that the steel membrane is tightly attached to the force angle plate, thereby avoiding a gap between the steel membrane and the force angle plate, resulting in an angle deviation during the placement of the steel membrane, causing the steel membrane to affect the slope gradient. At the same time, the slope accuracy of the flat slope surface formed after mechanical compaction impact under the joint action of the steel membrane and the slope surface flatness control device can be ensured.

[0013] (2) The present invention sets an anti-skid device so that the cross-shaped plate and two rollers cooperate to drive the rubber belt toward the steel membrane. The rubber belt increases the friction between the cross-shaped plate and the steel membrane, thereby avoiding the problem that the geogrid easily pulls the steel membrane away from the force-bearing angle plate and the pad during the laying process of the geogrid, thereby improving the stability of the steel membrane during use. The multiple indentations on the surface of the rubber belt further increase the friction of the rubber belt, thereby further avoiding the problem that the steel membrane slips off the force-bearing angle plate. At the same time, the cross-shaped plate, the force-bearing angle plate, the roller, the friction wheel, and the friction plate cooperate to drive the rubber belt to rotate once each time it is used, so that the contact surface of the rubber belt with the steel membrane will change when it is used next time, thereby avoiding the problem that one side of the contact surface of the rubber belt is in contact with the steel membrane for a long time, which easily causes the surface of the rubber belt to wear and become smooth, thereby reducing the use effect of the rubber belt; at the same time, the friction wheel, the telescopic rod, the skateboard, and the friction plate cooperate to make the telescopic rod drive the friction wheel to be close to the friction plate, thereby ensuring the stability of the friction plate driving the friction wheel to rotate, which helps the rubber belt to stably switch the contact surface with the steel membrane each time it is used.

[0014] (3) The present invention sets an anti-foreign matter device so that the roller, arc block, abutment rod, cross plate, cross bar, fixed column and cross plate cooperate to drive the knocking rod to hit the roller, the roller vibrates and drives the rubber belt to vibrate, and the rubber belt shakes off the foreign matter adhering to it, thereby avoiding the presence of foreign matter affecting the contact quality between the rubber belt and the steel mold, resulting in a reduction in the clamping force of the rubber belt, causing the steel film to easily shift or loosen, thereby improving the construction quality of the steel film acting on the fill slope; at the same time, the cross bar, fixed column, cross plate and cross plate cooperate to squeeze the elastic arc plate, the elastic arc plate will bulge and deform in the direction away from the cross plate, the elastic arc plate pushes the inner wall of the rubber belt to drive one side of the rubber belt to bulge, after one side of the rubber belt bulges, the indentation groove will deform, and the groove area of ​​the indentation groove will increase, the soil impurities stuck in the indentation groove are easy to separate from the indentation groove of the rubber belt, avoiding the problem of soil impurities stuck in the indentation groove affecting the use of the rubber belt.

Through the arrangement of the above structure, the slope flatness control device can adjust the slope angle according to different slope rates, and has a wider adaptability. The pull ring 4 is arranged on the outer side of the bottom plate 1, which is conducive to the circulation and transportation of the slope flatness control device. The slope flatness control device does not require an angle measuring device, and can synchronously control the slope rate. At the same time, during the soil filling compaction construction, the filler is directly piled behind the steel film without other protective measures. The compaction machinery can directly carry out compaction construction near the slope. Under the joint action of the steel film and the slope flatness control device, a flat slope is formed after mechanical compaction impact. The soil pressure of the fill near the slope behind the force angle plate 9 can be accurately measured by the pressure gauge 10, so that the compaction degree of the slope can be accurately controlled.

[0025] A slide bar 14 is penetrated and slidably installed on the rear side of the stress angle plate 9 close to the support plate 3, and a cross-shaped plate 15 is fixed on the right side of the slide bar 14. A nut 17 is fixed on the front side of the stress angle plate 9 close to the support plate 3. The internal thread of the nut 17 is connected with a threaded rod 16. The threaded rod 16 penetrates the stress angle plate 9, and the right end of the threaded rod 16 is rotatably connected to the left side of the cross-shaped plate 15. Through the setting of the above structure, the cross-shaped plate 15 will clamp the steel film on the outside of the stress angle plate 9 to ensure that the steel film is tightly attached to the stress angle plate 9, thereby avoiding a gap between the steel film and the stress angle plate 9, resulting in an angle deviation during the placement of the steel film, causing the steel film to affect the slope gradient. At the same time, it can ensure the slope accuracy of the flat slope formed after mechanical compaction and impact under the joint action of the steel film and the slope flatness control device.

[0026] The outside of the cross-shaped plate 15 is provided with an anti-skid device 6, which includes a rubber belt 61, a plurality of indented grooves 62, two rollers 63, two one-way bearings 64, two friction plates 65, and two friction wheels 66. The two rollers 63 are rotatably mounted on the top and bottom of the cross-shaped plate 15, respectively. The rubber belt 61 is transmission-connected to the outside of the two rollers 63. A plurality of indented grooves 62 are evenly and equidistantly arranged on the outside of the rubber belt 61. The two one-way bearings 64 are respectively fixed on the lower front side and the lower rear side outer wall of the cross-shaped plate 15. The one-way bearings 64 are used to control the one-way rotation of the lower roller 63. The two friction wheels 66 are respectively fixed on the The front and rear sides of the rotating shaft of the lower roller 63, two friction plates 65 are respectively fixed on the right front and right rear of the force angle plate 9, the top of the friction plate 65 is set as a rough surface, the outer wall of the friction wheel 66 is set as a rough surface, and the top of the friction plate 65 contacts the outer wall of the friction wheel 66. Through the setting of the above structure, the rubber belt 61 will rotate once each time it is used, so that the contact surface of the rubber belt 61 with the steel film will change when it is used next time, thereby avoiding the problem that the contact surface of one side of the rubber belt 61 is in contact with the steel film for a long time, which easily causes the surface of the rubber belt 61 to wear and become smooth, thereby reducing the use effect of the rubber belt 61.

[0027] The anti-slip device 6 also includes two telescopic rods 67 and two slide plates 68. A slide groove is provided on the side of the two friction plates 65 that are away from each other. The two slide plates 68 are slidably installed in the slide grooves corresponding to the two friction plates 65. The two telescopic rods 67 are respectively fixed on the top of the two slide plates 68. The sides of the two telescopic rods 67 that are close to each other are respectively rotatably connected with the sides of the two friction wheels 66 that are away from each other. Through the arrangement of the above structure, the telescopic rod 67 will drive the friction wheel 66 to be close to the friction plate 65, thereby ensuring the stability of the friction plate 65 driving the friction wheel 66 to rotate, which in turn helps the rubber belt 61 to stably switch the contact surface with the steel film each time it is used.

[0028] When in use, the length of the support screw 12 is changed according to the slope rate of the construction slope by adjusting the threaded barrel 13. The support screw 12 pushes the force angle plate 9 to change its angle. The position of the angle dial 2 corresponding to the positioning line on the force angle plate 9 is the slope of the slope. Then the slope is laid out. According to the slope laying position, the slope flatness control device is positioned and placed. A set of slope flatness control devices is placed with a longitudinal spacing of one meter, and the bottom plate 1 is inserted into the slope. A steel film is placed on the inner side of the pad 5. The steel film is one meter long and two meters wide. The geogrid is cut according to the reinforcement length. The length of the geogrid is the reinforcement length + the vertical wrapping length. , lay the first layer of geogrid: after reserving the vertical wrapping length of the geogrid, position it behind the steel membrane and fix it with U-shaped nails. Tension the laid geogrid and fix it with U-shaped nails at the end of the geogrid. The adjacent geogrids are overlapped by two meters and fixed with U-shaped nails. The next step is to fill the soil. Put the reserved grid on the slope on the other side of the steel membrane, use a dump truck or bucket machinery to unload the material in a vertical dumping manner, and gradually unload the material from the back of the steel membrane to the end of the geogrid. Then fill the soil. The thickness of the layered fill is between 30 cm and 50 cm. After reaching the layered fill thickness, carry out the filling compaction construction, first static compaction and then Vibration compaction: after one hour of compaction by the compaction machine, when the pressure gauge 10 reads the required pressure value, that is, the compaction degree of the slope surface reaches the compaction requirement, then the second layer of geogrid is laid, and the geogrid reserved for the first layer is connected to the second layer of geogrid, and the geogrid is fixed with a U-shaped nail at the tail end while tensioning. After the fill height reaches the steel film arrangement height, the bucket teeth of the excavator bucket are used to pass through the pull ring 4 and slowly pull out the slope surface for a certain distance of ten to twenty centimeters, then the steel film is removed, and then the bottom plate 1 is completely pulled out of the slope body, and the above steps are repeated until the slope surface construction is completed. The slope surface flatness control device can be used according to different slopes. The slope rate and the slope angle are adjusted, and the adaptability is wider. The pull ring 4 is arranged on the outside of the bottom plate 1, which is conducive to the circulation and transportation of the slope flatness control device. The slope flatness control device can synchronously control the slope rate without an angle measuring device. At the same time, when the filling is compacted, the filler is directly piled behind the steel film, and no other protective measures are required. The compaction machine can directly perform compaction near the slope. Under the joint action of the steel film and the slope flatness control device, a flat slope is formed after mechanical compaction and impact. The soil pressure of the fill near the slope behind the force angle plate 9 can be accurately measured by the pressure gauge 10, so that the compaction degree of the slope can be accurately controlled.When the steel film is placed on the inner side of the pad 5, the steel film is located between the stress angle plate 9 and the cross-shaped plate 15. The threaded rod 16 is rotated, and the threaded rod 16 is acted on by the thread of the nut 17, and the threaded rod 16 moves to the left. Under the joint action of the threaded rod 16 and the slide bar 14, the threaded rod 16 and the slide bar 14 pull the cross-shaped plate 15 toward the stress angle plate 9. The cross-shaped plate 15 clamps the steel film on the outside of the stress angle plate 9 to ensure that the steel film is close to the stress angle plate 9, thereby avoiding the gap between the steel film and the stress angle plate 9, resulting in angle deviation during the placement of the steel film, causing the steel film to affect the slope gradient. At the same time, it can ensure the accuracy of the slope of the flat slope formed after mechanical compaction and impact under the joint action of the steel film and the slope flatness control device. ;

[0029] At the same time, when the cross-shaped plate 15 is close to the stress angle plate 9, the cross-shaped plate 15 will drive the rubber belt 61 to approach the steel membrane through the two rollers 63. The rubber belt 61 increases the friction between the cross-shaped plate 15 and the steel membrane, thereby avoiding the problem that the geogrid is easy to pull the steel membrane away from the stress angle plate 9 and the pad 5 during the laying process of the geogrid, thereby improving the stability of the steel membrane during use. The several indentations 62 on the surface of the rubber belt 61 further increase the friction of the rubber belt 61, thereby further avoiding the problem that the steel membrane slips off the stress angle plate 9. In the process of approaching the force-bearing angle plate 9, the cross-shaped plate 15 drives the friction wheel 66 to move with it through the roller 63 below. Under the friction force between the friction wheel 66 and the friction plate 65, the friction plate 65 drives the friction wheel 66 to rotate, and the friction wheel 66 drives the roller 63 below to rotate. When the two rollers 63 rotate, the two rollers 63 drive the rubber belt 61 to rotate. Each time the cross-shaped plate 15 moves away from the force-bearing angle plate 9, the cross-shaped plate 15 drives the friction wheel 66 to move away from the force-bearing angle plate 9 through the roller 63 below. At this time, the roller 63 below is subjected to the one-way shaft. The bearing 64 is restricted from rotating, and the roller 63 restricts the friction wheel 66, so that the friction wheel 66 does not rotate. The friction wheel 66 between the friction plates 65 will slip at this time, and the rubber belt 61 will rotate once each time it is used, so that the contact surface of the rubber belt 61 with the steel film will change when the rubber belt 61 is used next time, thereby avoiding the problem that the contact surface of one side of the rubber belt 61 is in contact with the steel film for a long time, which easily causes the surface of the rubber belt 61 to wear and become smooth, thereby reducing the use effect of the rubber belt 61. When the friction wheel 66 is close to the force angle plate 9, the friction There is rolling friction between the wheel 66 and the friction plate 65. When the friction wheel 66 is away from the force angle plate 9, there is sliding friction between the friction wheel 66 and the friction plate 65. At the same time, during the movement of the friction wheel 66, the friction wheel 66 drives the slide plate 68 to move along the slide groove of the friction plate 65 through the telescopic rod 67. Under the elastic force of the telescopic rod 67, the telescopic rod 67 will drive the friction wheel 66 to be close to the friction plate 65, thereby ensuring the stability of the rotation of the friction wheel 66 driven by the friction plate 65, which helps to stably switch the contact surface with the steel film each time the rubber belt 61 is used.

[0031] The foreign body prevention device 7 includes a plurality of arc blocks 71, a plurality of knocking rods 72, two cross bars 73, two abutting rods 74, two fixed columns 75, and two cross plates 76. A circular groove is provided in the middle of the two rollers 63. A plurality of arc blocks 71 are evenly and equidistantly fixed on the inner walls of the circular grooves corresponding to the two rollers 63. The two fixed columns 75 are slidably installed on the upper and lower outer walls of the cross-shaped plate 15, respectively. The two cross plates 76 are respectively fixed on the ends of the two fixed columns 75 that are close to each other, and a spring is provided between the cross plate 76 and the outer wall of the cross-shaped plate 15. The two cross bars 73 are respectively fixed on the ends of the two fixed columns 75 that are away from each other. The two abutting rods 74 are respectively fixed on the middle part of one side of the cross bar 73 away from the cross plate 76. 2 is evenly and equidistantly fixed on the side of the cross bar 73 away from the fixed column 75, the end of the resistance rod 74 away from the cross bar 73 is semicircular, and the semicircular shape of the resistance rod 74 is located on the movement trajectory of the arc block 71, and the end of the knocking rod 72 away from the cross bar 73 contacts the outer wall of the roller 63. Through the arrangement of the above structure, the cross bar 73 drives the knocking rod 72 to hit the roller 63, the roller 63 vibrates and drives the rubber belt 61 to vibrate, and the rubber belt 61 shakes off the foreign matter adhering to it, thereby avoiding the existence of foreign matter affecting the contact quality between the rubber belt 61 and the steel mold, resulting in a reduction in the clamping force of the rubber belt 61, causing the steel film to be easily displaced or loosened, thereby improving the construction quality of the steel film acting on the fill slope.

[0032] The anti-foreign object device 7 also includes an elastic arc plate 77, which is fixed between the two transverse plates 76, and the outer wall of the elastic arc plate 77 on the side away from the cross-shaped plate 15 is in contact with the inner wall of the rubber belt 61.

The cross bar 73 drives the fixed column 75 and the cross plate 76 to move accordingly. The spring corresponding to the cross plate 76 is stretched. At this time, the knocking rod 72 will move away from the roller 63. When the arc block 71 no longer pushes the resistance rod 74, under the action of the spring elastic force corresponding to the cross plate 76, the cross plate 76 drives the cross bar 73 to return to its original position through the fixed column 75. The cross bar 73 drives the knocking rod 72 to impact the roller 63. The roller 63 vibrates and drives the rubber belt 61 to vibrate. The rubber belt 61 shakes off the foreign matter adhering to it, thereby preventing the presence of foreign matter from affecting the rubber belt 61 The contact quality between the rubber belt 61 and the steel mold causes the clamping force of the rubber belt 61 to be reduced, resulting in the problem that the steel film is easily displaced or loosened, thereby improving the construction quality of the steel film acting on the fill slope; at the same time, when the cross bar 73 drives the cross plate 76 to move toward the center of the cross plate 15 through the fixed column 75, the two cross plates 76 will squeeze the elastic arc plate 77, and the elastic arc plate 77 will bulge and deform in the direction away from the cross plate 15, and the elastic arc plate 77 will push the inner wall of the rubber belt 61 to drive one side of the rubber belt 61 to bulge. After one side of the rubber belt 61 bulges, the indentation groove 62 will be deformed, and the groove area of ​​the indentation groove 62 will become larger. At this time, the soil impurities stuck in the indentation groove 62 are easily separated from the indentation groove 62 of the rubber belt 61, avoiding the problem of soil impurities stuck in the indentation groove 62 affecting the use of the rubber belt 61.
