Technical Field

[0001] The present application relates to the technical fields of geotechnical engineering and slope greening engineering, and in particular to a slope greening construction process based on high-steep and dangerous rock belts. Background Art

[0002] Currently, high-steep and dangerous rock formations have always been a major concern for roadside slopes due to their inherent uncertainty and danger. With the acceleration of modern road construction, slope protection and management have become increasingly important. For cities promoting green roads, slope greening in high-steep and dangerous rock formations is a key focus. This is because slope greening can cover the unsightly exposed rocks in these areas, transforming them into beautiful green belts and improving driver comfort.

[0003] Regarding the above-mentioned related technologies, the applicant believes that it is very difficult to carry out greening construction on the steep and dangerous rock belt due to its large slope. Moreover, the steep and dangerous rock slopes do not have the basic conditions for planting greening, which further increases the difficulty of greening construction on the slopes of the steep and dangerous rock belt. Summary of the Invention

[0004] In order to improve the difficulty of greening construction on the slopes of high-steep and dangerous rock belts, the purpose of this application is to provide a slope greening construction process based on high-steep and dangerous rock belts.

[0005] The slope greening construction technology based on high-steep and dangerous rock belts provided in this application adopts the following technical solutions:

[0006] A slope greening construction process based on high-steep dangerous rock belts includes the following steps:

[0007] Flower bed construction steps: Build a flower bed on the slope of the horseway. The flower bed is made of mortar-made block stone. The mortar strength is M7.5 and the block stone strength is MU30. Plant reinforcement in the center and below the flower bed. Set a drainage hole 0.1m above the ground. Use a 110mm diameter PVC pipe to pre-buried the drainage hole.

[0008] Construction protection steps: Set up a row of temporary protective railings on the outside of the bridleway and the slope entrance. The temporary protective railings are connected to the inner side of the slope. The erection of temporary protective railings must meet the DBJ50 / T-123-2020 technical standards for building guardrails. They will be removed once the plant survival rate meets the requirements.

[0009] Gravel processing steps: manually discard the crushed stones at the foot of the slope, and hang a safety rope when manually throwing the stones;

[0010] Steps for planting green plants in the flower bed: cultivate the soil inside the flower bed, plant shrubs and vines in the flower bed, and plant trees at the foot of the slope. Workers hang safety ropes throughout the planting process.

[0011] Irrigation system installation steps: set up a water reservoir on the top of the slope, set up an irrigation sprinkler device in the flower bed, and connect the water reservoir and the irrigation sprinkler device.

[0012] By adopting the above technical solution, when carrying out slope greening construction on high-steep and dangerous rock belts, the flower bed is first built. The flower bed is the basis for planting plants. During the construction of the flower bed, temporary protective railings are built in advance. The protective railings can not only protect the flower bed, but also be used to hang workers' safety belts, so that workers are safer when working on high-steep and dangerous rocks, and it is also possible for workers to work on steep slopes; the gravel generated during the construction process is directly discarded at the foot of the slope and subsequently processed in a unified manner; through the above construction steps, the difficulty of greening construction on the slope of high-steep and dangerous rock belts can be further reduced, and the setting of flower beds, water reservoirs and irrigation sprinklers can further provide green plants on the slope with planting conditions and subsequent growth conditions.

[0013] Optionally, the irrigation sprinkler device includes a supporting middle frame, a supporting side frame, a sprinkler mechanism and a driving mechanism; the supporting middle frame is installed in the flower bed, and the supporting side frames are provided at each end of the supporting middle frame; the supporting side frames are provided with straight rails, the length direction of the straight rails is consistent with the length direction of the flower bed, and the sprinkler mechanism is slidably set on the straight rails; the driving mechanism is installed on the supporting middle frame, and the driving mechanism is used to drive the sprinkler mechanism to move along the length direction of the straight rails.

[0014] By adopting the above technical solution, when watering the plants in the flower bed, the water in the water reservoir is transported to the sprinkler mechanism, and then the sprinkler mechanism is driven by the driving mechanism to move along the length direction of the supporting side frame; since the length direction of the supporting side frame is consistent with the length direction of the flower bed, and there are two supporting side frames, that is, there are two sprinkler mechanisms; therefore, the two sprinkler mechanisms can water most of the plants in the flower bed, thereby increasing the coverage area of ​​the water and improving the watering effect.

[0015] Optionally, the driving mechanism includes a rotating motor, a driving shaft, a driven shaft and a threaded moving assembly; the rotating motor is installed on the supporting middle frame, the driving shaft is coaxially installed on the output shaft of the rotating motor and the end of the driving shaft away from the rotating motor is rotatably connected to the supporting middle frame, the driven shaft is rotatably set on the supporting middle frame, the driving shaft and the driven shaft are transmitted through gear meshing, and the length directions of the driving shaft, the driven shaft and the straight rail are consistent; the threaded moving assembly is respectively provided with one on the driving shaft and the driven shaft, and the threaded moving assembly automatically moves along the length direction of the driving shaft / driven shaft when the driving shaft / driven shaft rotates, and the threaded moving assembly is connected to the spray mechanism.

[0016] By adopting the above technical solution, the rotating motor is started, so that the rotating motor drives the driving shaft to start rotating. Since the driving shaft is transmitted through gear meshing, the driven shaft will also rotate with the driving shaft. At this time, the threaded moving component will move along the length direction of the driving shaft, thereby driving the spray mechanism to move synchronously on the supporting side frame, and finally realize the driving of the spray mechanism.

[0017] Optionally, the threaded moving assembly includes a threaded moving cylinder, a limit block and a connecting rod; the driving shaft and the driven shaft are both threaded rods, and the two threaded moving cylinders are threadedly sleeved on the driving shaft and the driven shaft respectively; the limit block is arranged on the threaded moving cylinder, and a stop groove is provided on the supporting middle frame along the length direction of the supporting middle frame, and the limit block is slidably inserted in the stop groove; one end of the connecting rod is connected to the threaded moving cylinder, and the other end is connected to the spray mechanism.

[0018] By adopting the above technical solution, when the rotating motor rotates, the driving shaft and the driven shaft rotate synchronously with the rotation of the output shaft of the rotating motor, and the two threaded moving cylinders are respectively threadedly matched with the driving shaft and the driven shaft. Therefore, when the driving shaft and the driven shaft are both rotating, the threaded moving cylinder will also rotate. Since the limit block on the threaded moving cylinder is inserted in the anti-rotation groove, the threaded moving cylinder cannot rotate at this time, but will move along the length direction of the driving shaft and the driven shaft; the movement of the threaded moving cylinder will synchronously move the spray mechanism, thereby achieving the effect of driving the spray mechanism to move more conveniently.

[0019] Optionally, the spray mechanism includes a moving block, an organ pipe and a spray head; the moving block is slidably set on a straight rail, the spray head is installed on the top of the moving block, and the spray hole of the spray head is vertically facing upward; one end of the organ pipe is connected to the spray head, and the other end is connected to the water tank at the top of the slope through a water pump.

[0020] By adopting the above technical solution, the water pump is started, and the water in the water reservoir will directly enter the sprinkler head through the organ pipe. The spray hole of the sprinkler head is vertically upward, and the sprayed water will be sprinkled around the sprinkler head, and the moving block will move synchronously with the threaded moving cylinder in the straight track; and because the water supply pipeline is an organ pipe and can be extended and retracted, the moving block will allow the water in the water reservoir to enter the sprinkler head normally through the organ pipe during the movement, thereby achieving the effect of normal water supply.

[0021] Optionally, a rotating shaft is rotatably provided on the moving block, a roller is coaxially provided at one end of the rotating shaft, and an engaging wheel is provided at the other end; a rolling groove is provided on the straight rail along the length direction of the straight rail, and the roller rolls in cooperation with the rolling groove; a rack is provided on the straight rail along the length direction of the straight rail, and the engaging wheel engages with the rack.

[0022] By adopting the above technical solution, as the meshing wheel meshes with the rack and the roller rolls in the rolling groove, the moving block can move more stably in the length direction of the straight rail.

[0023] Optionally, a bar-shaped through hole is provided on the straight rail, and a swing plate is rotatably provided on the straight rail on the bar-shaped through hole, the swing plate covers the bar-shaped through hole and the swing plate is located directly below the moving block; a swing assembly is provided on the moving block, and the swing assembly is used to drive the swing plate to swing back and forth when the moving block moves along the length direction of the straight rail; the moving block is hollow inside and has an open lower end, and a branch pipe is also connected to the organ pipe, one end of the branch pipe extends into the moving block and faces the swing plate.

[0024] By adopting the above technical solution, a branch pipe is connected to the organ pipe, which will transport part of the water to the moving block and flow to the swing plate; and when the moving block is moving, the swing assembly will drive the swing plate to swing continuously, so the water flowing onto the swing plate will continuously flow down from both sides of the swing plate and flow onto the plants in the flower bed; this part of the water will irrigate the plants that cannot be irrigated by the sprinkler head under the supporting side frame, thereby further increasing the coverage area of ​​​​plant irrigation in the flower bed.

[0025] Optionally, the rocking assembly includes a cam, which is arranged on a rotating shaft; a center rotating rod is provided in the middle of the bar-shaped through hole along the length direction of the bar-shaped through hole, and a center bar hole is opened in the middle of the rocking plate along the length direction of the rocking plate, and the center rotating rod is rotated through the center bar hole and is connected to the rocking plate for rotation, and the surface of the cam is in conflict with the upper plate surface of the rocking plate on the side of the center rotating rod; a torsion spring is provided between the center rotating rod and the rocking plate, and the torsion spring makes the half of the rocking plate close to the cam always have a tendency to rotate toward the side close to the cam.

[0026] By adopting the above technical solution, during the process of meshing the meshing wheel and the rack, the rotating shaft will rotate continuously, thereby driving the cam to rotate continuously; when the wheel surface on the cam that is shortest to the cam rotation center contacts the upper plate surface of the swing plate and then the wheel surface on the cam that is farthest from the cam rotation center contacts the upper plate surface of the swing plate, the plate surface of the swing plate close to the cam will change from a horizontal state to a tilted downward state; and when the wheel surface on the cam that is farthest from the cam rotation center contacts the upper plate surface of the swing plate and then the wheel surface on the cam that is shortest to the cam rotation center contacts the upper plate surface of the swing plate, under the torsion force of the torsion spring, the plate surface of the swing plate close to the cam will change from a tilted downward state to a tilted upward state; this repetition can realize the swinging motion of the swing plate, and achieve the effect of being more convenient to drive the swing plate to continuously swing motion during the movement of the moving block.

[0027] Optionally, a guide groove is provided on the edge of the upper plate surface of the swing plate, the length direction of the guide groove is consistent with the width direction of the swing plate, and a plurality of the guide grooves are arranged along the length direction of the swing plate.

[0028] By adopting the above technical solution, the provision of the guide groove can facilitate the water to flow down along the side of the swing plate, thereby improving the water's ability to guide the flow.

[0029] Optionally, a protective cover is provided on the supporting middle frame, and the protective cover covers the rotating motor.

[0030] By adopting the above technical solution, the provision of the protective cover can protect the rotating motor and prevent the rotating motor from being damaged by being soaked in water.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. When constructing slope greening on high-steep and dangerous rock belts, the first step is to build a flower bed. The flower bed is the foundation for planting plants. During the construction of the flower bed, temporary protective railings will be built in advance. The protective railings not only protect the flower bed, but also serve as a place for workers to hang their safety belts, ensuring safety for workers when working on high-steep and dangerous rocks, and also enabling workers to work on steep slopes. The debris generated during the construction process is directly discarded at the foot of the slope and subsequently processed in a unified manner. Through the above construction steps, the difficulty of greening construction on the slopes of high-steep and dangerous rock belts can be further reduced. In addition, the installation of flower beds, water reservoirs and irrigation sprinklers can further provide the green plants on the slope with planting conditions and subsequent growth conditions.

[0033] 2. Start the water pump. Water from the reservoir flows directly through the organ pipes into the sprinkler heads. The nozzles of the sprinkler heads face upward, and the water sprays all around the sprinkler heads. The moving block, driven synchronously by the threaded moving cylinder, moves within the straight track. Because the water supply pipes are retractable, the moving block allows water from the reservoir to flow through the organ pipes into the sprinkler heads, achieving a normal water supply effect.

[0034] 3. A branch pipe is connected to the organ pipe, which transports some water to the moving block and flows to the swing plate. When the moving block moves, the swing assembly drives the swing plate to swing continuously, so the water flowing onto the swing plate continuously flows down from both sides of the swing plate and flows onto the plants in the flower bed. This part of the water will irrigate the plants that are not irrigated by the sprinkler heads under the supporting side frames, thereby further increasing the coverage area of ​​the plants in the flower bed.

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.

[0042] A slope greening construction technology based on high steep dangerous rock belt, referring to Figure 1 , including the following steps:

[0043] Flower bed construction steps: Build a flower bed on the sidewalk. The flower bed is constructed using mortar masonry with an M7.5 mortar strength and an MU30 masonry strength. The bed must be free of weathering and cracks. The minimum thickness in the center of the flower bed should be no less than 200mm. Construction should be carried out using the mortar squeeze method, with a masonry strength of no less than 22kN / m³. Vertical joints and excessive horizontal joints should be avoided, and the quality should meet the requirements. The flower bed is 0.7m high and 0.3m wide. Depending on the width of the bridleway at different locations, it should be built 0.2-0.5m from the outside of the bridleway while maintaining overall linearity. Before construction, rebar is pre-installed below the center of the flower bed. HRB400 threaded bars are used, spaced 3m apart, with a diameter of 12mm, a depth of 0.3m, and an exposed length of 0.4m. 0.15m hooks are provided at the ends and integrated into the flower bed. A 2.5cm wide expansion joint should be set up every 15-20m and at the point where the terrain changes. The joint should be caulked with asphalt mastic to a depth of 150mm. Drain holes should be set up 0.1m from the ground. The drainage holes should be pre-buried with 110mm diameter PVC pipes and spaced 3m apart.

[0044] Construction and protection procedures: During construction, the outer side of the bridleway faces a steep slope. To protect construction workers, materials, and equipment and prevent accidents, a row of temporary guardrails will be erected outside the bridleway and the slope entrance. This serves to protect construction workers (with safety ropes) and subsequent maintenance personnel. The temporary guardrails should be erected so as not to obstruct construction and connect to the inner side of the slope to ensure overall stability. They must comply with the DBJ50 / T-123-2020 Technical Standard for Building Guardrails. The design life of the temporary guardrails is the construction period, followed by a three-year maintenance period. They will be removed once the plant survival rate reaches the required level. The temporary guardrails are constructed using a 1.2m high steel pipe frame with a 60mm diameter. In limestone areas, they are anchored to the ground using drilled grouting. In rocky areas, they are anchored using pre-buried C20 foundations with dimensions of 0.3×0.3×0.3m. Diagonal braces are installed every 10m, with a 60° inclination. A row of safety ropes is hung on the slope 1.5m above the bridleway, and the safety ropes are fixed to the slope with expansion bolts at intervals of 3m.

[0045] Gravel treatment steps: Due to the presence of many rubbles on the bridleway during the dangerous rock treatment, in order to facilitate the horizontal transfer of equipment and materials on the bridleway, the rubble on the bridleway needs to be removed. The removal method is to manually discard the rubble at the foot of the slope when the railing is built. In addition, on the west side of Area 1, there are many isolated boulders at the foot of the slope, which will be removed at this time. The removal method is to manually crush and remove them with a safety rope and discard them on the platform below. When manually throwing stones, the safety rope must be hung on the temporary protective railing;

[0046] Steps for planting green plants in the flower bed: Plant planting follows the principle of "trees → shrubs → grass", which is the order of plant selection under the best circumstances. At the same time, when selecting vegetation, it should be arranged in a staggered manner. When choosing trees, a certain number of shrubs and herbaceous plants should be matched with them, and when choosing shrubs, a certain number of herbaceous plants should be matched with them. In addition, in addition to considering the environmental adaptability of plants, the selection of plants must also consider the ecological balance and ecological coordination of local species, and must not cause ecological pollution; cultivate the seed soil on the inside of the flower bed, plant shrubs and vines in the flower bed, and plant trees at the foot of the slope. Workers must hang safety ropes throughout the planting process;

[0047] Irrigation system installation steps: set up a water reservoir on the top of the slope, set up an irrigation sprinkler device 1 in the flower bed, and connect the water reservoir and the irrigation sprinkler device 1;

[0049] The water in the water reservoir is directly transported to the spray mechanism 4, and then the water is sprayed around the supporting side frame 3 through the spray mechanism 4; since there are two supporting side frames 3, the water sprayed by the spray mechanisms 4 on the two supporting side frames 3 can cover most of the vegetation on the flower bed; and in addition, the two spray mechanisms 4 will move along the length direction of the straight rail 6 under the drive of the driving mechanism 5, so that the spray mechanism 4 can move while spraying, further increasing the coverage area of ​​the sprayed water.

[0052] After starting the rotating motor 51, the output shaft of the rotating motor 51 will drive the driving shaft 52 to rotate, and since the driving shaft 52 and the driven shaft 53 are transmitted through gear meshing, the driven shaft 53 will also rotate; and the two threaded moving cylinders 541 are respectively threadedly engaged with the driving shaft 52 and the driven shaft 53, so when the driving shaft 52 and the driven shaft 53 are both rotating, the threaded moving cylinder 541 will also rotate, and since the limit block 542 on the threaded moving cylinder 541 is inserted in the anti-rotation groove 21, the threaded moving cylinder 541 cannot rotate at this time, but will move along the length direction of the driving shaft 52 and the driven shaft 53; the movement of the threaded moving cylinder 541 will synchronously move the spray mechanism 4, thereby achieving the effect of driving the spray mechanism 4 to move more conveniently.

[0054] When the water pump is started, the water in the water reservoir will directly enter the sprinkler head 43 through the organ pipe 42. The spray hole of the sprinkler head 43 is vertically upward, and the sprayed water will be sprinkled around the sprinkler head 43, while the moving block 41 will be moved synchronously with the threaded moving cylinder 541 within the straight rail 6; and since the water supply pipeline is the organ pipe 42, which can be extended and retracted, the moving block 41 will allow the water in the water reservoir to enter the sprinkler head 43 normally through the organ pipe 42 during the movement, thereby achieving the effect of normal water supply.

With the cooperation of the guide rod and the sliding sleeve, the moving block 41 can move more stably on the straight rail 6.

[0056] When the moving block 41 moves along the length direction of the straight rail 6, the meshing wheel 72 at the end of the rotating shaft 7 will move along the length direction of the rack 62 while meshing with the rack 62, thereby driving the roller 71 to roll in the rolling groove 61, and then allowing the sliding sleeve to slide along the length direction of the guide rod. In this way, the moving block 41 can move stably on the straight rail 6 without being easily disengaged, thereby improving the movement stability of the moving block 41 on the straight rail 6.
