This structural form imposes a large load pressure on the frame beam, which is not conducive to structural safety. During the greening construction process, maintenance management such as water, nutrients, weeding, and replanting is also required.

DETAILED DESCRIPTION

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0017] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified; in the description of the present invention, the terms "lateral", "longitudinal", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0018] like Figure 1-2 As shown, the present invention provides an automatic maintenance system for deep arid loess roadbed slope greening construction period, which is arranged along the frame beam 1 of the slope and includes: A positioning member 2, the lower end of which is anchored inside the center of each vertex of the frame beam 1, and the upper end of which is exposed outside the frame beam 1 as a fixed matching end; The non-woven fabric 3 has through holes corresponding to the positions of the positioning members 2, and the through holes are used to be downwardly sleeved on the outside of the fixed matching end. The non-woven fabric 3 is used to cover the frame beam 1 and closely adhere to the slope surface; The limiting ball clamp 4 has a fixing clamp 5 at its lower end, which is used to temporarily clamp the non-woven fabric 3 fixed at the fixed matching end and press the lower side at the bottom. The upper end of the limiting ball clamp 4 is provided with a connecting channel 6 in the horizontal direction extending along the slope surface; The liquid delivery system includes a transverse pipe 7, the outer diameter of which is not larger than the inner diameter of the connecting channel 6. The transverse pipe 7 is arranged to pass through a row of connecting channels 6 in the transverse direction. A plurality of liquid outlets are arranged at intervals on the pipe section between two adjacent limiting ball clamps 4 on the transverse pipe 7. Each liquid outlet is provided with an atomizing nozzle 8. One end of the transverse pipe 7 is sealed and connected to a rotating drive motor 9, and the other end is connected to a hydraulic pump 11 through a flexible telescopic tube 10. The hydraulic pump 11 is used to pump liquid into the transverse pipe 7.

[0019] For the convenience of explanation, Figure 1 The main view is divided into longitudinal and transverse directions, the left and right sides are transverse, the upper and lower sides are longitudinal, the horizontal direction in which the extension direction of the slope is located is transverse, and the inclination direction of the slope is longitudinal. The longitudinal direction is parallel to the slope surface and perpendicular to the extension direction of the slope. When constructing the slope frame beam 1, a positioning member 2 is pre-embedded and set, and the frame beam 1 is anchored after concrete is poured to expose the upper end of the positioning member 2. The fixed matching end and the limit ball clamp 4 can adopt a variety of matching forms, such as bolt connection, setting pin holes and pin shafts 21 and then fastening the two ends, hinged and other detachable fixing methods to ensure that the position of the connecting channel 6 is horizontal; the required plant variety seeds and Corresponding nutrients are added, and then covered with non-woven fabric 3 for heat preservation and moisture retention, to protect the growth of plant seeds inside and prevent the soil in the frame from being blown away by strong winds. Non-woven fabric 3 is a water-permeable or water-seeping material. Non-woven fabric 3 is sleeved on positioning member 2 by setting a through hole. Positioning member 2 is used to form support and positioning, so that non-woven fabric 3 fits the soil surface in the frame as much as possible, which is beneficial to ensure the water retention and heat preservation capacity in each frame. Then the limiting ball clamp 4 is installed, and the bottom of the limiting ball clamp 4 abuts against the frame beam 1 downward to press the non-woven fabric 3 around the through hole to prevent the non-woven fabric 3 from being lifted up. In this way, there is no need to set up other additional fixing structures to fix the non-woven fabric 3, and the damage to the non-woven fabric 3 itself is very small.

[0020] After the limiting ball clamp 4 is installed, a transverse tube 7 is inserted into a row of horizontal connecting holes 6. The transverse tube 7 can slide relatively in the connecting holes 6. The transverse tube 7 can be prefabricated or connected as a whole according to the required length. The transverse tube 7 has a certain structural strength and can withstand the pumping of the internal liquid under a certain pressure. Water is generally passed into the transverse tube 7. Under the action of the atomizing nozzle 8, water is sprayed on the area in the lower frame. The right end of the transverse tube 7 is connected to the hydraulic pump 11 through a flexible telescopic tube 10, and the left end is coaxially driven and connected to the rotating drive motor 9 after being blocked. The flexible telescopic tube 10 is connected to the hydraulic pump 11 through a flexible telescopic tube 10. The tube 10 is mainly adapted to have certain axial and circumferential changes. A certain length of space can be reserved at the flexible telescopic tube 10, or other bearing + sealing ring connection forms can be used. According to the weather and wind direction of the slope greening location, the rotary drive motor 9 can drive the cross tube 7 to rotate at a smaller angle, thereby changing the direction of the atomizing nozzle 8 in the vertical plane, and making the current spraying height of the atomizing nozzle 8 higher; of course, the cross tube 7 can be arranged according to the spraying range capacity and the required intervals, and is not limited to being arranged in each row of connecting channels 6.

[0021] The automatic maintenance system for deep arid loess roadbed slope greening construction period of the present invention includes a positioning member 2 anchored on a frame beam 1, a non-woven fabric 3 covering and laid on the slope surface, a limiting ball clamp 4 arranged at the upper end of the positioning member 2 and a liquid delivery system. The positioning member 2 has a positioning and supporting effect on the non-woven fabric 3 with through holes. The limiting ball clamp 4 further presses the non-woven fabric 3 on the frame beam 1, which is beneficial to improve the moisture retention and heat preservation capacity of the inner side of the frame of the frame beam 1 on the deep arid loess slope. The liquid delivery system uses the limiting ball clamp 4 for support and installation, and can automatically spray the lower frame through a hydraulic pump 11 and an atomizing nozzle 8, which significantly reduces the amount of manual work and improves the efficiency and safety of maintenance construction.

The liquid delivery system also includes a longitudinal pipe 14, which passes through a row of downward passages 13 along the slope surface, and the upper end of the longitudinal pipe 14 is connected to the water reservoir 12 through a valve, and the lower end of the longitudinal pipe 14 is detachably sealed with a bottom end cover, and two columns of liquid outlets are symmetrically provided on the pipe section of the longitudinal pipe 14 located between two adjacent limiting ball clamps 4, and a nozzle is provided on each liquid outlet, and a sealing end cover is detachably provided at the bottom of the longitudinal pipe 14.

[0023] A downward passage 13 is provided at the upper end of the limiting ball clamp 4. The downward passage 13 does not interfere with or communicate with the connecting pipe. The downward passage 13 serves as a guide for the longitudinal pipe 14. The inner diameter of the downward passage 13 is not less than the outer diameter of the longitudinal pipe 14. The water reservoir 12 can be used as a natural water storage system. A cover plate can be set when necessary to reduce evaporation or pollution of water in the pool. Rainwater is received or required water or a mixed liquid or treatment liquid with nutrients is directly added. A filter screen is set at the valve port, and then the water is passed into the longitudinal pipe 14. The water reservoir 12 mainly relies on gravity to supplement and maintain the area inside the frame from the side and utilize natural rainwater.

[0024] In another technical solution, Figure 1-2 As shown, the bottom of the longitudinal tube 14 is provided with support legs 15 spaced axially downward, the distance between the longitudinal tube 14 and the frame beam 1 is consistent with the length of the support legs, and the bottom of the support legs 15 is a rubber structure and supported at the corresponding position of the geotextile. The support legs 15 can support the longitudinal tube 14 upward and strengthen the temporary fixing effect of the non-woven fabric 3 below.

By designing the lower end structure of the support leg 15, the lower end of the support leg 15 adapts to the shape of the frame beam 1, increases the contact area, and better presses the non-woven fabric 3 to fit the slope surface.

[0026] In another technical solution, Figure 1-2 As shown, it also includes a slide rail member 16 that is repeatedly overlapped along a row of the limit ball clamps 4, a hanging ring 17 is arranged on the top of the fixed matching end in a lateral direction perpendicular to the slope surface, and a concave cavity 18 is opened on the upper end of the slide rail member 16 toward the side of the frame beam 1, and the concave cavity 18 is arranged in cooperation with the hanging ring 17. A plurality of convex columns 19 are arranged on the top of the slide rail member 16 along the length direction, and a plurality of grooves are arranged at the bottom corresponding to the convex columns 19. Adjacent slide rail members 16 are overlapped by embedding the convex columns 19 into the grooves. The slide rail member 16 located at the top is As a head slide rail member 16, an upper pin hole 20 is opened at the upper end of the head slide rail member 16 toward the center of the hanging ring 17, and a pin shaft 21 is inserted into the upper pin hole 20 and the hanging ring 17 at the corresponding position. The length of the pin shaft 21 is greater than the sum of the lengths of the upper pin hole 20 and the concave cavity 18. Slide grooves are symmetrically opened on both sides of the slide rail member 16, and a slide box 22 for placing objects is slidably connected to the outside of the slide rail member 16 through a pair of slide grooves. The upper end of the slide box 22 is open, and the bottom of the slide box 22 is provided with a limit clamp 23 for temporary positioning on the slide rail member 16.

[0027] When the non-woven fabric 3 needs to be removed, first remove the rotary drive motor 9, the hydraulic pump 11 and the cross tube 7, then remove the limit ball clamp 4, uncover the non-woven fabric 3, first use the convex column 19 and the groove to overlap the adjacent slide rail parts 16, and then buckle it on the hanging ring 17 through the concave cavity 18 to achieve length direction limitation, and then insert the pin 21 into the upper pin hole 20 on the head slide rail part 16, and the pin 21 passes through the hanging ring 17 corresponding to the position of the head slide rail part 16 to achieve the limitation of the slide rail part 16 in the direction perpendicular to the slope surface. The upper end of the pin 21 can be set to a T-shaped or L-shaped elbow design.

[0028] In another technical solution, Figure 1-2As shown, the upper end of the fixed mating end is set as a disc 24 structure, and the lower end is set as a vertical plate 25 structure. The outer end of the disc 24 is symmetrically provided with a pair of notches inwardly along the same diameter direction. The vertical plate 25 is connected to the bottom center of the disc 24 and the width direction of the vertical plate 25 is perpendicular to the direction of the line connecting the pair of notches. Racks are symmetrically provided on both sides of the vertical plate 25.

The inner sides of both ends of the fixing clamp 5 have clamping teeth, which are matched with the rack. A spring-pressing portion 26 is provided at the bottom of the fixing clamp 5. The spring-pressing portion 26 extends along the opening direction of the notch to abut the geotextile downward and press it against the plane on the frame beam 1.

[0029] The notch itself can play a certain limiting role on the fixing clamp 5 in the width direction. The through hole of the non-woven fabric 3 is set according to the structural elasticity of the non-woven fabric 3 itself and the cross-sectional shape of the fixed matching end. The notch is set to facilitate the fixing clamp 5 to pass through the notch downward and be clamped on both sides of the vertical plate 25. The clamping teeth on the fixing clamp 5 are meshed with the rack to form a stable temporary fixation. The size of the spring-pressing part 26 is set according to the position of the non-woven fabric 3 outside the through hole below, and it is sufficient to flatten part of the non-woven fabric 3. The spring-pressing part 26 is set as a rubber structure to avoid damaging the non-woven fabric 3.

[0030] In another technical solution, Figure 1-2 As shown, the two sides of the middle of the vertical plate 25 symmetrically protrude outward to form an arc segment 27, and the inner sides of the middle of both ends of the fixing clamp 5 are provided with an arc clamp structure matched with the arc segment 27 to further increase the meshing area.
