Description

Technical Field

[0001] This invention relates to the field of ecological slope drainage technology, specifically to a water-storage ecological drainage ditch and drainage method for highway slopes. Background Technology

[0002] When paving roads in areas with loose soil, the road slopes are one of the key areas of concern. Due to soil conditions, the slopes are prone to erosion during rainy weather, which can not only damage the road but also harm the natural environment. Therefore, for road slopes in such environments, drainage methods and protection effects must be given utmost importance.

[0003] Chinese patent CN116289394B discloses a water-storing ecological drainage ditch for highway cutting slopes, comprising a ditch body located on the slope, with multiple planting troughs at the bottom of the inner cavity of the ditch body. A breathable and waterproof layer is fixedly connected to the inner cavity of each planting trough body, and a communication port is provided at the bottom of the inner cavity of each planting trough body. A seepage-proof valve is provided between the planting trough body and the ditch body, and the seepage-proof valve includes a ventilation pipe extending through one side of the inner cavity of the planting trough body, with one end of the ventilation pipe extending into the ditch body. By placing the planting troughs inside the ditch body, while satisfying the drainage needs of the ditch body, the planting troughs retain rainwater, retaining more water for the growth of trees and shrubs, forming a diversified ecological community structure, and avoiding the risk of simple herbaceous communities being drought-intolerant and prone to degradation.

[0004] Although the above invention can achieve a certain effect of water retention and herb fixation by setting the planting trough body in the intercepting ditch body, the protection effect on the inclined part of the slope is weak due to the limited area where the planting trough body is set. Moreover, the inclined part is also a key area for soil erosion during rainy weather. As a result, soil erosion will still occur under long-term rain erosion, making it difficult to achieve the ideal protection effect on the slope. Summary of the Invention

[0014] A water-storage ecological drainage method for highway slopes includes drainage during rainy weather and water replenishment during dry weather. During rainy weather, natural rainwater is collected and stored using a water storage well. During dry weather, a water circulation component is used to automatically replenish the slope's moisture content, providing water for the planted vegetation on the slope and improving the survival rate of the planted vegetation.

[0015] Preferred steps for collecting rainwater during rainy weather include: S1. When rain falls, the water flows down the slope, the beam absorbs and intercepts some of the rainwater, and some of the rainwater overflows the beam and flows down to the drainage ditch. S2. The drainage ditch receives rainwater during rainy weather, and the cover plate filters the incoming rainwater. At the same time, the rainwater in the drainage ditch flows through the intercepting channel to the water storage well, which is used to store the collected rainwater. S3. When the water storage well is not full of rainwater, the rainwater inside the drainage ditch flows into the water storage well through the intercepting channel. S4. When the water storage well is full of rainwater, the water interception channel is level with the water surface of the drainage ditch. Then, the rainwater inside the drainage ditch flows along the drainage ditch and eventually flows to the external outlet.

[0016] Preferred steps for water replenishment during drought include: D1. The humidity detector detects the humidity on the top surface of the sealing plate. When the humidity detector detects that the humidity on the top surface of the sealing plate is higher than or equal to the preset humidity value, the water pump is in a dormant state. When the humidity detector detects that the humidity on the top surface of the sealing plate is lower than the preset humidity value, D2 is executed. D2. The water pump starts and pumps the rainwater stored inside the well cavity to the slope through the water circulation component. The pumped rainwater seeps out through the outer protective block, increasing the water content of the slope and keeping the planting soil moist.

[0017] The beneficial effects of this invention are: 1. This highway slope water-storage ecological drainage ditch uses water-conducting pipes, insert pipes, and return pipes inside the beams to return water to the upper well cavity, thereby effectively improving the drainage effect of the slope and achieving simultaneous drainage of the slope soil surface and interior. This effectively improves the drainage effect of the slope, reduces the destructive effect of rainwater on the slope, and further enhances the protective effect of the beams on the slope through the diamond-shaped distribution of the beams. Combined with the ecological protection of the slope surface planting, it effectively reduces soil erosion on the slope, thus ensuring not only the drainage effect of the slope but also the protection effect of the slope.

[0018] 2. This highway slope water-storage ecological drainage ditch uses moisture-retaining ropes to infiltrate water into the slope soil, directly permeating and moisturizing the soil from within, thereby effectively reducing water waste and improving soil irrigation. The use of multiple moisture-retaining ropes further ensures the uniformity of soil irrigation. During plant growth, the ropes facilitate the entanglement of plant roots with the soil, further increasing the tightness of the connection between plants, soil, and the ditch, thus improving the slope protection effect.

[0019] 3. This ecological drainage method for highway slope water storage uses a humidity detector to detect the humidity in the upper well cavity, determines the soil moisture content of the slope, and uses the humidity value measured by the humidity detector to determine the start of the water pump, realizing the automatic control of water replenishment of the slope by the water circulation component, thereby achieving the ecological cycle effect of water storage and replenishment, and effectively ensuring the survival of vegetation on the slope.

[0020] 4. This ecological drainage method for road slope water storage uses a humidity detector to detect the humidity in the upper well cavity, determines the soil moisture content of the slope, and uses the humidity value measured by the humidity detector to determine the start of the water pump, realizing the automatic control of water replenishment of the slope by the water circulation component, thereby achieving the ecological cycle effect of water storage and replenishment, and effectively ensuring the survival of vegetation on the slope.

[0023] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1 Please see Figure 1 - Figure 12 A type of ecological drainage ditch for roadside slope water storage includes a slope 1, a road surface 2, a drainage ditch 3 and a cover plate 4. Several beams 5 are embedded in the slope 1. The ends of the beams 5 are spliced ​​together to form a diamond-shaped mesh covering the slope 1. A water interception trough 8 is provided inside the drainage ditch 3. Several water storage wells 9 are provided at the bottom of the water interception trough 8. A number of drill rods 6 are provided on the outside of the beam plate 5. A fixing screw 7 is provided between the drill rods 6 and the beam plate 5. An outer protective block 61 is provided on the outside of the drill rods 6. A moisturizing mechanism is provided inside the outer protective block 61. The outside of the slope 1 is used for planting green plants. A water circulation component 14 is provided between the slope 1 and the water storage well 9. The water circulation component 14 includes a water pump for driving water flow. The water storage well 9 includes an upper well chamber 91 and a lower well chamber 92. A sealing plate 93 is provided between the upper well chamber 91 and the lower well chamber 92. A guide column 94 for connecting the lower well chamber 92 is fixedly connected to the top of the sealing plate 93. A humidity detector 95 is provided on the top of the sealing plate 93. The water pump is electrically connected to the humidity detector 95. The beam slab 5 is made of absorbent bricks, and the bottom side of the slope 1 is embedded with an anti-slip curb 12. The anti-slip curb 12 is fixedly connected to the outside with an anti-slip column 13.

[0025] During the laying process, according to the highway construction drawings, the slope 1 is excavated to the set slope, and the water circulation component 14 and the drill rod 6 are pre-embedded, and the soil is backfilled and compacted. At the same time, trenches are pre-excavated at the locations of beams and slabs 5 to be laid as needed, and placement grooves for outer protective blocks 61 are pre-excavated at the splicing locations of beams and slabs 5. Lay the beam slab 5. The splicing position of the beam slab 5 coincides with the drill rod 6. By driving in the fixing screw 7, the fixing screw 7 and the drill rod 6 are connected by threads, thereby completing the splicing of different beam slabs 5. The drill rod 6 also strengthens the contact effect between the beam slab 5 and the slope 1. Anti-slip barriers 12 are laid on slope 1 and beam 5. The height of the anti-slip barriers 12 above the ground is not less than 10cm. At the same time, anti-slip columns 13 are driven into the bottom of the anti-slip barriers 12 to increase the support of slope 1 and beam 5 and prevent slope 1 and beam 5 from sliding down.

[0026] A drainage ditch 3 is excavated between the slope 1 and the road surface 2, and a water interception channel 8 is further excavated inside the drainage ditch 3. At the same time, water storage wells 9 are excavated at intervals inside the water interception channel 8, with an interval of no less than 2 meters between adjacent water storage wells 9.

[0027] It should be noted that the cover plate 4 is a precast cement slab with transverse or longitudinal through grooves. The cover plate 4 is used to filter rainwater and prevent large-volume garbage or branches from flowing into the drainage ditch 3, thereby preventing the drainage ditch 3 from becoming clogged and improving the use effect of the drainage ditch 3.

[0028] It should be noted that the intercepting trough 8 is closer to the road surface 2, and the drainage ditch 3 is closer to the slope 1. When it rains, the rainwater flowing down from the slope 1 first flows through the cover plate 4 into the interior of the drainage ditch 3, and then flows into the interior of the intercepting trough 8.

[0029] Furthermore, when rainwater flows into the interior of the intercepting trough 8, under the diversion effect of the intercepting trough 8, the rainwater flows to different water storage wells 9 respectively, and the rainwater stays in the interior of the upper well cavity 91 and the lower well cavity 92 respectively.

[0030] The upper well chamber 91 is used to temporarily store collected rainwater. When the rainwater reaches a specified amount, it flows into the lower well chamber 92, which is used to ultimately store the collected rainwater.

[0031] The sealing plate 93 is used to improve the water storage effect of the lower well chamber 92 and prevent water evaporation.

[0032] refer to Figure 1 , Figure 2 and Figure 4 In an optional embodiment, a retaining wall 10 is provided between the drainage ditch 3 and the intercepting trough 8. Several protective plates 11 are laid on the top of the intercepting trough 8. The bottom surface of the intercepting trough 8 is lower than the bottom surface of the drainage ditch 3. The water storage well 9 is excavated at intervals at the bottom of the intercepting trough 8. The water storage well 9, the intercepting trough 8 and the drainage ditch 3 are all plastered with cement and covered with waterproof mortar.

[0033] When rainwater flows into the interior of the intercepting trough 8, it is filtered by the cover plate 4 and the baffle 10, which further improves the quality of the rainwater inside the intercepting trough 8. During cleaning, the top of the cover plate 4 and the interior of the drainage ditch 3 can be cleaned separately, which effectively reduces the frequency of cleaning the interior of the intercepting trough 8 and thus improves the performance of the drainage ditch 3.

[0034] refer to Figure 11 and Figure 12 In one optional embodiment, the guide column 94 has an "n"-shaped through hole inside, with one through hole of the guide column 94 connecting to the upper well chamber 91 and the other through hole of the guide column 94 connecting to the lower well chamber 92.

[0035] It should be noted that when rainwater flows from inside the intercepting trough 8 to the upper well cavity 91, the rainwater stays inside the upper well cavity 91. When the rainwater height reaches the top of the "n"-shaped through hole of the guide column 94, the guide column 94 forms a communicating vessel, allowing the rainwater at the top of the upper well cavity 91 to flow into the lower well cavity 92 through the guide column 94, where the rainwater is further stored.

[0036] The sealing plate 93 effectively reduces the evaporation of rainwater inside the lower well cavity 92, thereby improving the rainwater storage effect inside the lower well cavity 92.

[0037] Furthermore, a protective plate 11 is laid on the top of the upper well cavity 91. The protective plate 11 is used to reduce the evaporation of rainwater inside the upper well cavity 91, so that the humidity of the top of the upper well cavity 91 is positively correlated with the moisture content of the deep soil of the slope 1. By using a humidity detector 95 to detect the humidity of the upper well cavity 91, the soil moisture content of the slope 1 is determined. Using the humidity value measured by the humidity detector 95, the water pump is started to realize the automatic control of the water circulation component 14 to replenish the water of the slope 1, thereby achieving the ecological cycle effect of water storage and replenishment, effectively ensuring the survival of the plants on the slope 1.

[0038] refer to Figures 2-4 In an optional embodiment, the water circulation component 14 includes a pumping pipe 141, a branch pipe 142, a connecting pipe 143, and a guide pipe 144. At least one guide pipe 144 is provided, and the guide pipe 144 is connected to several drill rods 6. The connecting pipe 143 is used to connect several guide pipes 144 and the pumping pipe 141. The pumping pipe 141 is connected to the interior of the water storage well 9 through the branch pipe 142. The water pump is provided outside the pumping pipe 141 and is used to pump the stored water through the pumping pipe 141 to several guide pipes 144. The humidity detector 95 is designed with a start-up module on its exterior. The start-up module includes a preset humidity value. When the humidity detector 95 detects that the humidity is lower than the preset humidity value, the start-up module is used to control the water pump to start.

[0039] It should be noted that the diversion pipe 144 and the connecting pipe 143 are pre-embedded and laid during the construction of the slope 1. The pumping pipe 141 can be placed in the intercepting trench 8. The pumping pipe 141 is connected to several branch pipes 142. The branch pipes 142 extend into the interior of the lower well cavity 92. The pumping pipe 141 is used to extract water stored in the lower well cavity 92 of different water storage wells 9 through several branch pipes 142.

[0040] The preset humidity value is set according to the type of plants planted on slope 1 and the external climate conditions.

[0041] refer to Figures 1-3 , Figures 8-10 In an optional embodiment, a water guide pipe 51 is fixedly connected inside the beam plate 5. The water guide pipe 51 has an opening on its side. A return pipe 15 is provided inside the anti-slip curb 12. An insertion pipe 52 is fixedly connected to the bottom end of the water guide pipe 51. The insertion pipe 52 is inserted into the inside of the return pipe 15. The return pipe 15 is connected to the upper well cavity 91.

[0042] It should be noted that when the soil moisture content of slope 1 increases, the water flows through the beam 5 into the water pipe 51, then flows through the water pipe 51 to the bottom, then flows through the insertion pipe 52 to the return pipe 15, and then the water flows back to the upper well cavity 91 through the return pipe 15.

[0043] Specifically, during rainy weather, rainwater flowing from the top of slope 1 to drainage ditch 3, as well as rainwater infiltrating into beam slab 5 from the soil of slope 1, flows back to upper well cavity 91 through water guide pipe 51, insertion pipe 52, and return pipe 15 inside beam slab 5. This effectively improves the drainage effect of slope 1, achieving simultaneous drainage of the soil surface and interior of slope 1, thereby effectively improving the drainage effect of slope 1 and reducing the destructive impact of rainwater on slope 1. At the same time, the diamond-shaped distribution of beam slab 5 further enhances the protective effect of beam slab 5 on slope 1. Combined with the ecological protection of vegetation on the surface of slope 1, this effectively reduces soil erosion of slope 1, thus ensuring not only the drainage effect of slope 1 but also its protective effect.

[0044] During drought, when the humidity detector 95 detects that the humidity in the upper well cavity 91 is lower than the preset humidity value, the humidity detector 95 controls the water pump to work through the start module. The water pump draws rainwater stored in the lower well cavity 92 through the pumping pipe 141 and the branch pipe 142, and then transports it to the non-contained diversion pipe 144 through the connecting pipe 143. The rainwater is transported to the outer protective block 61 through the diversion pipe 144, allowing the rainwater to infiltrate into the soil of the slope 1 through the outer protective block 61, thereby increasing the soil moisture content. When the soil moisture content increases, the excess water infiltrates into the diversion pipe 51 through the beam slab 5, and then flows back to the upper well cavity 91. The humidity detector 95 then detects an increase in the humidity value, and the water pump stops working.

[0045] The water circulation component 14, the return pipe 15, and the humidity detector 95 effectively ensure the water replenishment effect of the soil on the slope 1, ensuring sufficient soil water replenishment so that the plants on the slope 1 can maintain a good growth environment, thereby effectively improving the survival rate and growth status of the plants and ensuring the ecological protection effect of the plants on the slope 1.

[0046] It should be noted that the water pumps are set in sections. One water pump ensures the water replenishment circulation of a section of slope 1. Each section of slope 1 is no less than 100 meters long. Each section of slope 1 has at least one humidity detector 95. When the humidity value detected by the detector is lower than the preset humidity value, the water pump of that section will start.

[0047] refer to Figures 5-7 and Figure 12 In one optional embodiment, the drill rod 6 includes a rod tip, a rod body, and a tail rod. The rod body and the tail rod are connected by an outer protective block 61. A guide tube 144 is installed between the rod tip and the rod body. A connecting cavity 62 is formed inside the rod body. The connecting cavity 62 is connected inside the outer protective block 61. An outer anchor rod 63 that can extend to the outside of the outer protective block 61 is movably connected inside the outer protective block 61. A positioning pin 64 is fixedly connected to the tail end of the outer anchor rod 63. A drive plate 65 is rotatably connected inside the outer protective block 61. A guide plate 66 is fixedly connected inside the outer protective block 61. The drive plate 65 has a through centrifugal groove. The guide plate 66 has a guide groove along the radial direction. The positioning pin 64 passes through the centrifugal groove and is slidably connected in the guide groove.

[0048] The drill rod 6 is pre-embedded in the slope 1 during the excavation of the slope 1. The tip of the drill rod 6 is welded to the outside of the guide pipe 144, and the rod body is fixedly connected to the other side of the guide pipe 144. A connecting cavity 62 is opened inside the rod body. The connecting cavity 62 is used to connect the guide pipe 144 and the outer protective block 61. The top of the rod body is threaded to the outer protective block 61, and the tail rod is threaded to the top of the outer protective block 61.

[0049] It should be noted that when the drive plate 65 rotates, the drive plate 65, together with the guide plate 66, can drive the outer anchor rod 63 to move outward, so that the outer anchor rod 63 is inserted into the inner layer of the soil, further increasing the locking effect on the soil of the slope 1 and effectively preventing soil erosion of the slope 1.

[0050] refer to Figures 5-7 The drive plate 65 has a shaft fixedly connected to a collar 67 that rotates inside the outer protective block 61. The drill rod 6 has a drive ring 68 that is movably connected inside. The drill rod 6 has an inner positioning rod 614 that is fixedly connected inside. The drive ring 68 is sleeved on the outside of the inner positioning rod 614. The drive ring 68 and the inner positioning rod 614 are slidably connected by a keyway and a key. A support spring 69 is provided between the drive ring 68 and the inner positioning rod 614. A matching drive pin and a spiral groove are provided between the drive ring 68 and the collar 67. The drive ring 68 is used to drive the collar 67 to rotate through the drive pin and the spiral groove. The guide tube 144 is connected to the drainage cavity 613 through the connecting cavity 62 and the outer protective block 61 of the drive ring 68.

[0051] It should be noted that the collar 67 is located between the rod body and the tail rod of the drill rod 6. The drive ring 68, the inner positioning rod 614, and the support spring 69 are all located inside the connecting cavity 62. The top of the drive ring 68 is in sealed contact with the drill rod 6. The top of the drill rod 6 is provided with a threaded cavity that matches the fixing screw 7. The top of the drive ring 68 is connected to the threaded cavity. When the fixing screw 7 fixes the beam plate 5 and the drill rod 6, the fixing screw 7 pushes the drive ring 68. The drive ring 68 compresses the support spring 69 and moves downward. When the drive ring 68 moves downward, the drive ring 68 drives the collar 67 to rotate. The collar 67 drives the drive plate 65 to rotate, thereby pushing the outer anchor rod 63 to move outward.

[0052] Furthermore, the inner positioning rod 614 has an opening at the top. When rainwater flows into the outer protective block 61, the rainwater flows through the guide pipe 144 to the connecting cavity 62 of the drill rod 6, through the opening at the top of the inner positioning rod 614 to the inside of the drive ring 68, and then from the drive ring 68 to the outer protective block 61.

[0053] It should be noted that there are multiple models of fixing screw 7, the specific difference being the length of fixing screw 7. The length of fixing screw 7 determines the length of the outer anchor rod 63 that is pushed out. By selecting fixing screw 7 of different lengths, the pushing out length of the outer anchor rod 63 can be controlled.

[0054] It should be noted that the drive ring 68 has a side opening. In the initial state, the side opening of the drive ring 68 fits against the inner wall of the connecting cavity 62, so that the connecting cavity 62 and the outer protective block 61 are isolated. When the drive ring 68 moves downward, when the outer anchor rod 63 is pushed out to the outside of the outer protective block 61, the drive ring 68 can connect to the outer protective block 61 through the side opening.

[0055] Furthermore, by selecting fixed screws 7 of different lengths, the connection between the connecting cavity 62 and the outer protective block 61 can be controlled, thereby adjusting the soil infiltration and moisture retention area and infiltration nodes of the slope 1, thus effectively ensuring the flexibility of soil moisture retention control of the slope 1.

[0056] refer to Figure 6 and Figure 7 In one optional embodiment, a support plate 610 is rotatably connected inside the outer protective block 61. A moisturizing rope 611 is wound around the top of the support plate 610. A placement groove is opened on the top of the outer anchor rod 63. One end of the moisturizing rope 611 passes through the support plate 610 and is accommodated in the placement groove. An upper partition plate 612 is fixedly connected inside the outer protective block 61. The upper partition plate 612 forms a drainage cavity 613 on the top of the support plate 610. A through guide hole is opened on the upper partition plate 612 to connect the drainage cavity 613 and the space of the moisturizing rope 611.

[0057] It should be noted that the tip of the outer anchor rod 63 is provided with a pin for fixing the moisturizing rope 611. When the moisturizing rope 611 is placed in the top placement groove of the outer anchor rod 63, the end of the moisturizing rope 611 is fixed in position by the pin, thereby ensuring that when the outer anchor rod 63 is inserted into the soil, the outer anchor rod 63 can simultaneously drive the moisturizing rope 611 to extend out of the outer protective block 61.

[0058] Specifically, when rainwater enters the outer protective block 61, the rainwater enters the drainage cavity 613 through the side hole via the drive ring 68, and then enters the area where the moisturizing rope 611 is located through the guide hole, so that the moisturizing rope 611 is combined with the rainwater and moistened. Then, the outer protective block 61 infiltrates water into the soil of the slope 1 through the moisturizing rope 611, and the moisture is directly infiltrated from the soil, thereby effectively reducing water waste and improving the soil irrigation effect. Furthermore, the infiltration and moisturization through several moisturizing ropes 611 further improves the uniformity of soil irrigation on the slope 1.

[0059] It should be noted that during the plant growth process, the plant roots and the moisturizing rope 611 can easily become entangled, which further increases the tightness of the connection between the plant, soil and the rod 6, thereby improving the protection effect on the slope 1.

[0060] Example 2 A water-storage ecological drainage method for highway slopes includes drainage during rainy weather and water replenishment during dry weather. During rainy weather, natural rainwater is collected and stored using a water storage well 9. During dry weather, the water circulation component 14 automatically replenishes the water content of the slope 1 to provide water for the planted vegetation on the slope 1, thereby improving the survival rate of the planted vegetation on the slope 1.

[0061] In an optional embodiment, the rainwater collection step during rainy weather includes: S1. When rain falls, the water flows down through the slope 1. The beam 5 absorbs and intercepts some of the rainwater, and some of the rainwater overflows the beam 5 and flows down to the drainage ditch 3. S2, Drainage ditch 3 receives rainwater during rainy weather, while cover plate 4 filters the incoming rainwater. At the same time, the rainwater in drainage ditch 3 flows through intercepting channel 8 to water storage well 9, which is used to store the collected rainwater. S3. When the water storage well 9 is not full of rainwater, the rainwater inside the drainage ditch 3 flows into the water storage well 9 through the intercepting channel 8. S4. When the water storage well 9 is full of rainwater, the water interception channel 8 is level with the water surface of the drainage ditch 3. Then the rainwater inside the drainage ditch 3 flows along the drainage ditch 3 and eventually flows to the external outlet.

[0062] In an optional embodiment, the water replenishment step during drought weather includes: D1. Humidity detector 95 detects the humidity on the top surface of sealing plate 93. When the humidity detector 95 detects that the humidity on the top surface of sealing plate 93 is higher than or equal to the preset humidity value, the water pump is in a dormant state. When the humidity detector 95 detects that the humidity on the top surface of sealing plate 93 is lower than the preset humidity value, D2 is executed. D2. The water pump starts and pumps the rainwater stored inside the lower well chamber 92 to the slope 1 through the water circulation component 14. The pumped rainwater permeates outward through the outer protective block 61, increasing the water content of the slope 1 and keeping the planting soil of the slope 1 moist.
