Description

Technical Field

[0001] This invention belongs to the field of slope stabilization technology, specifically relating to a maintenance structure for steep slopes. Background Technology

[0002] In recent years, large-scale engineering construction and mining have led to the formation of numerous exposed slopes in karst landforms, resulting in a large number of rock slopes that cannot be revegetated. It is almost impossible to naturally restore vegetation cover on these slopes in the short term. Therefore, protective structures are usually set up on the slopes to plant vegetation. However, existing artificial slope greening and reconstruction projects are mostly aimed at rock slopes with a slope of less than 75°. However, during the construction process, rock slopes with a slope greater than 75° or even 90° are often encountered. The common solution for such slopes is to clean the rock slope to reduce its slope. However, this method involves a large amount of construction work, a long time period, and is relatively dangerous. Therefore, in view of the above problems, we propose a protective structure for steep slopes. Summary of the Invention

[0003] To overcome the problems existing in related technologies, this invention discloses a protection structure for steep slopes.

[0004] To achieve the above objectives, one technical solution adopted by the present invention is:

[0005] A maintenance structure for steep slopes includes a vegetation unit and a drip irrigation system. The drip irrigation system includes a main water pipe, a distribution valve on the main water pipe, a water collection container connected to the distribution valve, and drip irrigation pipes. Water entering the water collection container can enter the drip irrigation pipes through the distribution valve, and water entering the main water pipe can enter the drip irrigation pipes through the distribution valve.

[0006] Furthermore, the distribution valve includes an inner cylinder connected to the lower side of the water collection container and communicating with the water collection container, a piston cylinder that is sealed and slidably assembled to the outside of the inner cylinder, an outer cylinder that is sealed and slidably connected to the outside of the piston cylinder and whose upper end is fixed to the inner cylinder and whose lower end is connected to the main water pipe, and a first elastic element that is fixed to the inner side of the outer cylinder and fixed to the lower end of the piston cylinder.

[0007] The lower end of the inner cylinder is closed and a drainage groove is provided on the side. A water storage limiting member is provided on the inner side of the inner cylinder above the drainage groove. When there is no water in the water collection container, the limiting part of the water storage limiting member will not extend out of the inner cylinder. When there is water in the water collection container, the water pressure applied to the water storage limiting member can make the limiting part extend out of the inner cylinder.

[0008] The piston cylinder has an inner docking groove on its inner side and an outer docking groove on its outer side that is located below the inner docking groove and communicates with the inner docking groove.

[0009] The outer cylinder has a first connecting pipe that communicates with the outer cylinder and is located below the drainage trough, and the drip irrigation pipe is connected to the first connecting pipe.

[0010] Furthermore, the water storage limiting component also includes an installation cylinder fixed to the inner side of the inner cylinder, a sliding plate sealed and slidably assembled in the installation cylinder, and a second elastic member, the left and right ends of the second elastic member being fixedly connected to the sliding plate and the inner cylinder, respectively.

[0011] The inner cylinder has a clearance groove on its side that communicates with the mounting cylinder, and the limiting part is fixed to the side of the sliding plate near the clearance groove.

[0012] Furthermore, a second connecting pipe is fixedly connected to the lower end of the outer cylinder, and the main water pipe is connected to the second connecting pipe through a side water pipe.

[0013] Furthermore, the lower end of the first elastic element is fixedly connected to the lower end of the inner side of the outer cylinder.

[0014] Furthermore, the distance between the inner docking groove and the outer docking groove is equal to the distance between the drainage groove and the first connecting pipe.

[0015] Furthermore, the outer cylinder has a vent hole located on the upper side of the water storage limiting member.

[0016] Furthermore, the upper end of the inner cylinder has a connecting ring plate, which is fixed to the water collection container by multiple bolts.

[0017] Furthermore, a water collection container trough is provided above the planter to accommodate the water collection container.

[0018] Furthermore, the side of the planter is provided with a drip irrigation pipe through hole for the drip irrigation pipe to pass through.

[0019] This invention discloses a maintenance structure for steep slopes. The vegetation units of this maintenance structure can be arrayed and laid on steep slopes to green the slopes at large angles. In addition, the drip irrigation system of this maintenance structure can irrigate the vegetation in the vegetation units. The drip irrigation system can also collect rainwater for drip irrigation, which can save water to a certain extent and reduce maintenance costs. Attached Figure Description

Detailed Implementation

[0032] The invention will now be further described with reference to the accompanying drawings.

[0033] Reference Figure 1-9 As shown, the nursing structure in this embodiment includes a planter 1 and a drip irrigation system. The planter 1 is used to install on the slope to plant plants, and the drip irrigation system is used to drip irrigate the plants in the planter 1.

[0034] In this embodiment, the planter 1 includes a mounting frame 101 with an open top and a planter frame 102 placed inside the mounting frame 101. The mounting frame 101 has an inverted trapezoidal hollow structure. One side of the mounting frame 101 has four rectangularly distributed bolt mounting holes 1011. The bottom of the mounting frame 101 also has several drainage holes 1012 for drainage. The sides and bottom of the planter frame 102 are provided with several ventilation grooves 1021 to facilitate root respiration.

[0035] The vegetation unit 1 of this slope protection structure is mainly used on rocky slopes with an angle greater than 75 degrees or even 90 degrees. In specific use, four rectangularly distributed explosion bolts 3 are fixed on the slope 4. Then, the mounting frame 101 is fitted onto the four explosion bolts 3 through the four bolt assembly holes 1011. Nuts 31 are then screwed onto the explosion bolts 3 inside the mounting frame 101 to fix the mounting frame 101 to the slope 4. Then, the vegetation frame 102 is placed inside the mounting frame 101, thus completing the installation of the vegetation unit 1. Artificial soil can then be filled into the vegetation frame 102 to plant vegetation. Later, the vegetation in the vegetation frame 102 can be drip-irrigated through a drip irrigation system to allow it to grow for a long time. In this way, vegetation maintenance can be carried out on rocky slopes with large slopes. Compared with the traditional slope reduction method, slope protection using the protection structure can significantly reduce the difficulty of the work and improve safety. In addition, the components of the protection structure can be prefabricated and only need to be installed on the slope site, which can reduce the amount of construction and greatly improve work efficiency.

[0036] In this embodiment, the drip irrigation system includes a main water pipe 21, a distribution valve 22 installed on the main water pipe 21, a water collection container 23 connected to the distribution valve 22, and a drip irrigation pipe 24. The water collection container 23 and the drip irrigation pipe 24 are both installed above the planter 1. The water collection container 23 is used to collect rainwater or water flowing down from the planter 1. The water in the water collection container 23 can enter the drip irrigation pipe 24 through the distribution valve 22 to drip irrigate the vegetation in the planter 1. In addition, the water in the main water pipe 21 can also enter the drip irrigation pipe 24 through the distribution valve 22 to drip irrigate the vegetation in the planter 1.

[0037] In this embodiment, the distribution valve 22 includes an inner cylinder 221, a piston cylinder 222, an outer cylinder 223, a first elastic element 224, and a water storage limiting element 225.

[0038] In this embodiment, a connecting ring plate 2214 is connected to the upper end of the inner cylinder 221, and the connecting ring plate 2214 is fixed to the water collection container 23 by multiple bolts 2215. A through hole 231 is provided at the bottom of the water collection container 23, and the water collection container 23 communicates with the inner cylinder 221 through the through hole 231. The lower end of the inner cylinder 221 is a closed structure, and a drainage groove 2211 is provided on the side of the inner cylinder 221.

[0039] In this embodiment, the piston cylinder 222 is slidably and sealed to the outside of the inner cylinder 221. The piston cylinder 222 is a hollow structure. An inner docking groove 2221 for docking with the drainage groove 2211 is provided on the inner side of the piston cylinder 222, and an outer docking groove 2222 located below the inner docking groove 2221 is provided on the outer side of the piston cylinder 222. Since the piston cylinder 222 is a hollow structure, the inner docking groove 2221 and the outer docking groove 2222 will be interconnected.

[0040] In this embodiment, the outer cylinder 223 is slidably and sealed to the outside of the piston cylinder 222 and its upper end is fixed to the inner cylinder 221. The outer cylinder 223 has a first connecting pipe 2212 that communicates with the outer cylinder 223 and is located below the drainage groove 2211. The drip irrigation pipe 24 is connected to the first connecting pipe 2212. In addition, a second connecting pipe 2231 is fixedly connected to the lower end of the outer cylinder 223, and the main water pipe 21 is connected to the second connecting pipe 2231 through the side water pipe 211.

[0041] Preferably, the distance between the inner docking groove 2221 and the outer docking groove 2222 is equal to the distance between the drainage groove 2211 and the first connecting pipe 2212.

[0042] In this embodiment, the first elastic element 224 is a helical spring, and the upper and lower ends of the first elastic element 224 are fixedly connected to the lower end of the piston cylinder 222 and the lower end of the inner side of the outer cylinder 223, respectively.

[0043] In this embodiment, the water storage limiting member 225 is disposed inside the inner cylinder 221 and above the drainage channel 2211. The water storage limiting member 225 includes a limiting part 2251, a mounting cylinder 2252, a sliding plate 2253, and a second elastic member 2254. The mounting cylinder 2252 is horizontally fixedly disposed inside the inner cylinder 221. The sliding plate 2253 is sealed and slidably assembled inside the sliding plate 2253. The left and right ends of the second elastic member 2254 are respectively fixedly connected to the side wall of the sliding plate 2253 and the inner wall of the inner cylinder 221. A relief groove 2213 communicating with the mounting cylinder 2252 is provided on the side of the inner cylinder 221. The limiting part 2251 is fixedly connected to the side of the sliding plate 2253 near the relief groove 2213, and the limiting part 2251 can extend out of the inner cylinder 221 from the relief groove 2213.

[0044] When the first elastic member 224 is in its naturally extended state, the inner wall of the piston cylinder 222 closes the drainage groove 2211, and the outer wall of the drainage groove 2211 closes the first connecting pipe 2212. In this state, the inner docking groove 2221 and the outer docking groove 2222 are located on the lower side of the drainage groove 2211 and the first connecting pipe 2212, respectively.

[0045] When the second elastic member 2254 is in its natural elongation state, the limiting part 2251 will be retracted into the inner cylinder 221, that is, the limiting part 2251 will not extend out of the relief groove 2213.

[0046] To avoid the space above the piston cylinder 222 being a closed space, a vent 2232 is opened on the side of the outer cylinder 223 above the water storage limit component 225 so that the piston cylinder 222 can slide smoothly up and down.

[0047] After water is stored in the water collection container 23, the water in the water collection container 23 will enter the inner cylinder 221 through the guide hole 231. The water entering the inner cylinder 221 will enter the mounting cylinder 2252 and contact the sliding plate 2253. Under the action of water pressure, the sliding plate 2253 will overcome the elastic force of the second elastic element 2254 and be pushed by the water towards the relief groove 2213 side, so that the sliding plate 2253 pushes the limiting part 2251 to extend out of the inner cylinder 221 through the relief groove 2213. In this way, when the piston cylinder 222 slides upward, the limiting part 2251 can limit the piston cylinder 222.

[0048] When there is no water in the water collection container 23, the slide plate 2253 will not be pressurized by water, and the limiting part 2251 will be held in the inner cylinder 221 under the elastic force of the second elastic member 2254. In this state, the piston cylinder 222 that slides upward can pass smoothly through the water storage limiting member 225.

[0049] When drip-irrigating the vegetation inside the planter 1, the water pump is controlled to pump water into the main water pipe 21. The water entering the main water pipe 21 will enter the outer cylinder 223 through the side water pipe 211 and the second connecting pipe 2231. The water entering the outer cylinder 223 will overcome the elastic force of the first elastic element 224 and push the piston cylinder 222 upward, causing the piston cylinder 222 to slide upward. If the water collection container 23 contains water, the piston cylinder 222 will slide upward until it abuts against the limiting part 2251. In this state, the inner docking... The groove 2221 will be aligned with the drainage groove 2211, and the outer docking groove 2222 will be aligned with the first connecting pipe 2212. In this way, the water in the water collection container 23 can be guided into the piston cylinder 222 through the drainage groove 2211 and the inner docking groove 2221 on the inner cylinder 221, and then guided into the drip irrigation pipe 24 through the outer docking groove 2222 and the first connecting pipe 2212 on the piston cylinder 222. In this way, the drip irrigation pipe 24 can drip water into the planter 1 through the drip hole 241 to irrigate the vegetation. If the water collection container 23 is empty, the piston cylinder 222, which slides upward, will not be restricted by the limiting part 2251. The piston cylinder 222 can continue to slide upward until its lower end is lower than the lower end of the first connecting pipe 2212. At this time, the water in the outer cylinder 223 can be guided into the drip irrigation pipe 24 through the first connecting pipe 2212. In this way, the drip irrigation pipe 24 can drip water into the planter 1 through the drip hole 241 to irrigate the vegetation.

[0050] Thus, when the drip irrigation system irrigates the plant 1, it only needs to control the water pump to pump water into the main water pipe 21 to irrigate the vegetation. It is worth mentioning that the distribution valve 22 can select the drip irrigation water according to whether there is water in the water collection container 23. If there is no water in the water collection container 23, the water in the main water pipe 21 will be used for drip irrigation. If there is water in the water collection container 23, the water in the water collection container 23 will be used first for drip irrigation to save water and reduce the maintenance cost of vegetation.

[0051] It is worth mentioning that in practical applications, multiple planters 1 can be laid out side by side in a straight line, so that one drip irrigation system can be used to irrigate multiple planters 1. A water collection container trough 11 can be opened above the planters 1, so that multiple planters 1 can directly support the water collection container 23 through the water collection container trough 11. In addition, drip irrigation pipe through holes 12 can be opened on the side of the planters 1 for drip irrigation pipes 24 to pass through, so that drip irrigation pipes 24 can pass through each planter 1 to irrigate the vegetation in each planter 1. Correspondingly, each planter 1 can also support the drip irrigation pipe 24 through the drip irrigation pipe through holes 12.

[0052] In summary, this invention discloses a maintenance structure for steep slopes. The vegetation units of this maintenance structure can be arrayed and laid on steep slopes to green the slopes at large angles. In addition, the drip irrigation system of this maintenance structure can irrigate the vegetation in the vegetation units. The drip irrigation system can also collect rainwater for drip irrigation, which can save water to a certain extent and reduce maintenance costs.

[0053] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
