Technical Field
[0001] This utility model relates to the field of municipal engineering and greening facilities technology, specifically a green plant composite cover that integrates with the surrounding green environment. Background Technology
[0002] In municipal engineering, the covers of various inspection wells, valve wells and other facilities are usually made of concrete, metal or composite materials. Their appearance is mostly a single gray or metallic color, which is difficult to blend with the surrounding green environment. This not only affects the overall landscape harmony, but also the traditional cover has a single function, which can only cover the well opening and cannot meet the needs of modern cities for expanding green areas and beautifying the landscape. In addition, traditional manhole covers have shortcomings in drainage performance. When it rains, water easily accumulates on the manhole covers, affecting pedestrian passage and potentially damaging the covers themselves, reducing their service life. Moreover, the accumulated water will all flow into the well, resulting in poor sealing. Therefore, there is an urgent need for a composite manhole cover that can blend in with the surrounding green environment, has good drainage performance, and is structurally stable. To this end, a green plant-type composite manhole cover that blends in with the surrounding green environment is proposed. Utility Model Content
[0003] The purpose of this invention is to solve the above problems by proposing a green plant-type composite cover that integrates with the surrounding green environment.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a green plant composite cover that integrates with the surrounding green environment, characterized in that: it includes a cover base, a barrier set around the perimeter of the cover base, a drainage and storage plate laid on top of the cover base to provide a water storage foundation for the green plants, and a pull ring kit that penetrates the drainage and storage plate and is fixedly connected to the cover base; the barrier is provided with a plurality of drainage holes for draining excess water.
[0005] Preferably, it also includes lateral supports at both ends that connect to the enclosure to increase lateral stiffness.
[0006] As a preferred option, it also includes a permeable geotextile and a layer of expanded clay aggregate laid sequentially above the drainage and storage board.
[0007] Preferably, the lateral support is provided with several water-permeable holes.
[0008] Preferably, the transverse support is provided with stiffening ribs at both ends that connect to the enclosure.
[0009] Preferably, the top of the enclosure is covered with a rubber sealing strip.
[0010] Preferably, several reinforcing angle steels are pre-embedded on the cover plate base and at the connection between the cover plate base and the enclosure.
[0011] Preferably, the cover plate base and the enclosure are made of high-strength concrete with built-in steel reinforcement.
[0012] Preferably, the pull ring assembly includes a pull ring that vertically penetrates the drain plate and the cover plate base and has threads at the lower end, a steel sleeve fitted around the outer periphery of the pull ring, a water-resistant rubber filling the gap between the steel sleeve and the pull ring, a positioning nut screwed onto the threaded section of the pull ring and abutting against the upper end face of the steel sleeve to limit the position of the steel sleeve on the pull ring, a fixing nut screwed onto the threaded section of the pull ring and located below the positioning nut, and a gasket fitted onto the pull ring and placed between the fixing nut and the cover plate base.
[0013] The beneficial effects of this utility model are as follows: Through the structure of the cover plate base, enclosure, drainage and storage plate, and drainage holes, a good environment for plant growth is provided, allowing the cover plate to be planted with greenery, integrating it with the surrounding green environment and enhancing the harmony of the urban landscape; moreover, the cover plate base, as the basic load-bearing structure of the cover plate, is cast with high-strength concrete and steel reinforcement, possessing high compressive strength, durability, and insulation, increasing the safety performance of the cover plate; the enclosure is integrally cast with the cover plate base, forming a circumferential structure around the edge of the cover plate base, used to define the growth area for greenery. The long-area drainage system prevents the planting substrate from overflowing. The drainage and storage board is laid on top of the cover plate base. Its internal protrusions and grooves can temporarily store and slowly release rainwater, providing a continuous moist environment for the green plants planted above. At the same time, the grooves on the drainage and storage board form drainage channels that connect with the drainage holes distributed on the fence. When the water accumulation above the drainage and storage board exceeds the preset water level, the excess water can be discharged into the soil around the cover plate through the drainage holes, preventing water from flowing into the well. This provides a suitable water environment for the growth of green plants and also avoids damage to the green plants due to waterlogging. The lateral support increases the lateral stiffness of the cover plate, preventing deformation of the drainage and storage plate and the base plate due to external impact or pressure from plant growth. The stiffening ribs at both ends of the lateral support further enhance the stability of the connection between the lateral support and the enclosure, improving the overall structural stability of the cover plate. The permeable holes facilitate the flow of water in the planting soil, increasing the permeability of soil moisture on both sides of the lateral support. By installing rubber sealing strips, the fence can be cushioned when it is bumped during transportation or planting, reducing the risk of damage to the top of the fence. At the same time, it prevents rainwater from entering the well from the top of the fence along the side of the fence, thus achieving a sealing effect. Through the synergistic effect of angle steel, concrete, and reinforcing bars, stress concentration is effectively dispersed, thereby improving the crack resistance and load-bearing capacity of the overall structure.

For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0019] See appendix Figure 1 - Appendix Figure 5 As shown in the figure, this embodiment of a green plant composite cover plate that blends into the surrounding green environment is characterized by: including a cover plate base 1, a fence 2 set around the perimeter of the cover plate base 1, a drainage and storage plate 3 laid on the cover plate base 1 to provide a water storage base for the green plants, and a pull ring kit 4 that penetrates the drainage and storage plate 3 and is fixedly connected to the cover plate base 1; the fence 2 is provided with a plurality of drainage holes 21 for draining excess water.
[0020] The enclosure 2 can be fixed by bolts, welding, riveting, sliding connection, or integral casting with the perimeter of the cover plate base 1. When casting is used, the cover plate base 1 and the enclosure 2 are integrally formed by high-strength concrete with built-in steel bars. The high-strength concrete is UHPC high-strength concrete. The drainage and storage plate 3 is made of HDPE material, with regularly arranged protrusions and grooves on the surface. The grooves form drainage channels. During laying, it is ensured that the drainage channels are unobstructed. Adjacent drainage and storage plates 3 are connected by overlapping, and the overlap gap is ensured to prevent the planting soil and other filling materials from falling off due to excessive gap. The height of the enclosure 2 should be sufficient to accommodate the drainage and storage plate 3 and the space required for the growth of green plants. The height of the enclosure 2 should match the support structure of the well opening. After planting, it should be compatible with other plants in the surrounding area. The drainage holes 21 are evenly distributed in the lower half of the enclosure 2 and are inclined downward. During drainage, excess water can be smoothly discharged from the drainage holes 21 on the enclosure 2 along the drainage channel. The structure, including the cover plate base 1, enclosure 2, drainage and storage plate 3, and drainage holes 21, provides a good environment for plant growth, allowing the cover plate to be planted with greenery and blending seamlessly with the surrounding green environment, thus enhancing the harmony of the urban landscape. Furthermore, the cover plate base 1, as the foundation load-bearing structure, is constructed of high-strength concrete and reinforced steel, possessing high compressive strength, durability, and insulation, increasing the safety performance of the cover plate. The enclosure 2 is integrally cast with the cover plate base 1, forming a circumferential structure around the edge of the cover plate base 1, its function being to define the plant growth area. The drainage and storage plate 3 is laid on top of the cover plate base 1 to prevent the planting substrate from overflowing. Its internal protrusions and grooves can temporarily store and slowly release rainwater, providing a continuous moist environment for the green plants planted above. At the same time, the grooves on the drainage and storage plate 3 form drainage channels that connect with the drainage holes 21 distributed on the enclosure 2. When the water accumulation above the drainage and storage plate 3 exceeds the preset water level, the excess water can be discharged into the soil around the cover plate through the drainage holes 21, preventing water from flowing into the well. This provides a suitable water environment for the growth of green plants and also avoids damage to the green plants due to waterlogging.
[0021] In one embodiment, the system further includes a transverse support 5 connected to the enclosure 2 at both ends to increase lateral stiffness; the transverse support 5 is provided with a plurality of water-permeable holes 51; and the transverse support 5 is provided with stiffening ribs 52 connected to the enclosure 2 at both ends.
[0022] The lateral support 5 and stiffening rib 52 are made of steel. The lateral support 5 is connected to the stiffening rib 52 by welding or bolts. The stiffening rib 52 can be connected to the enclosure 2 by pre-embedding or bolts. The three form a stable triangular support structure. When the cover plate is long, a lateral support 5 can be set on the drainage and storage plate 3 along the width of the cover plate to enhance the lateral stiffness of the cover plate. If the cover plate is small, it is not necessary to set a lateral support 5 to meet the load-bearing requirements.
[0023] The lateral stiffness of the cover plate is increased by the setting of the transverse support 5, which prevents the water storage plate 3 and the base 1 of the cover plate from deforming due to external impact or pressure from the growth of green plants. The stiffening ribs 52 at both ends of the transverse support 5 enhance the stability of the connection between the transverse support 5 and the enclosure 2, and improve the overall structural stability of the cover plate. The permeable holes 51 facilitate the flow of water in the planting soil and increase the permeability of soil moisture on both sides of the transverse support 5.
[0024] In one embodiment, the system further includes a permeable geotextile and a layer of expanded clay aggregate laid sequentially above the drainage and storage board 3. The permeable geotextile has good permeability and filtration properties, which can prevent planting soil particles from seeping into the cavity of the drainage and storage board 3 and causing blockage. The expanded clay aggregate is lightweight and porous, and when laid above the permeable geotextile, it can form a buffer layer, which is conducive to water infiltration and can provide a breathable environment for plant roots, while reducing the direct pressure of the planting soil on the drainage and storage board 3.
[0025] See appendix Figure 3 - Appendix Figure 5 As shown, the top of the enclosure 2 is covered with a rubber sealing strip 7; the rubber sealing strip 7 can act as a buffer when the enclosure 2 is bumped during transportation or planting, reducing the risk of damage to the top of the enclosure 2, and at the same time preventing rainwater from entering the well from the top of the enclosure 2 along the side of the enclosure 2, thus playing a sealing role.
[0026] See appendix Figure 2 As shown, several reinforcing angle steels 6 are pre-embedded on the cover plate base 1 and at the connection between the cover plate base 1 and the enclosure 2; through the synergistic effect of the angle steels 6, concrete, and reinforcing steel, stress concentration is effectively dispersed, and the crack resistance and load-bearing capacity of the overall structure are improved.
[0027] See appendix Figure 5 As shown, the pull ring assembly 4 includes a pull ring 41 that vertically penetrates the drain and storage plate 3 and the cover plate base 1 and has threads at the lower end; a steel sleeve 42 that is sleeved on the outer periphery of the pull ring 41; a water-proof rubber 43 that fills the gap between the steel sleeve 42 and the pull ring 41; a positioning nut 44 that is screwed onto the threaded section of the pull ring 41 and abuts against the upper end face of the steel sleeve 42 to limit the position of the steel sleeve 42 on the pull ring 41; a fixing nut 45 that is screwed onto the threaded section of the pull ring 41 and is located below the positioning nut 44; and a gasket 46 that is sleeved on the pull ring 41 and placed between the fixing nut 45 and the cover plate base 1.
[0028] The lower end of the pull ring 41 is threaded. The pull ring 41 vertically penetrates the water storage plate 3 and the cover plate base 1, providing an installation base for the entire pull ring assembly 4. The steel sleeve 42 is fitted onto the pull ring 41, providing a certain degree of protection for the pull ring 41. The water-proof rubber 43 fills the gap between the steel sleeve 42 and the pull ring 41, effectively preventing water from seeping into the cover plate base 1 through the gap and entering the well through the cover plate base 1. The positioning nut 44 is screwed onto the pull ring 41, and its lower end face abuts against the upper end face of the steel sleeve 42, which can fix the position of the steel sleeve 42. The fixing nut 45 and the washer 46 cooperate to firmly connect the pull ring 41 to the cover plate base 1, ensuring the reliability of the pull ring assembly 4 connection. At the same time, it also facilitates the opening and closing operation of the cover plate.
[0029] In the process of using this utility model, the cover plate is first lifted to the well opening position using the pull ring kit 4 to ensure that the cover plate completely covers the well opening; then, on the base plate 1, the drainage and storage board 3, permeable geotextile, expanded clay layer and planting soil are laid in sequence. The expanded clay layer can play a role in air permeability, water filtration and buffering, while the drainage and storage board 3 can create a water storage and water guiding space. The two work together to provide a suitable environment for subsequent green plant growth that is breathable, water-retaining and not prone to root rot; when laying the drainage and storage board 3, special attention should be paid to the overlapping surface between the boards to ensure that the overlap is tight and without gaps, to prevent the subsequently laid planting soil from falling into the drainage channel of the drainage and storage board 3 and avoiding channel blockage that would cause the drainage function to fail; after the laying is completed, the green plants are planted in the planting soil of the cover plate and it can be put into use.
[0030] When it rains or a large amount of water accumulates inside the cover, the excess water in the soil will seep through the expanded clay layer and the permeable geotextile in sequence, and finally flow into the drainage channel of the water storage board 3. Then the water flows along the drainage channel, is discharged from the cover through the pre-set drainage holes 21 on the enclosure 2, and seeps into the soil around the cover, realizing the rapid drainage of water and preventing water accumulation at the roots of green plants. To further improve waterproofing, the top of the enclosure 2 is equipped with a sealing strip 7, which can effectively prevent rainwater from seeping into the well from the top of the enclosure 2 along its side. At the same time, the pull ring kit 4 is equipped with a water-proof rubber 43, which can prevent water from seeping into the interior of the cover base 1 along the pull ring 41, ultimately eliminating the risk of water entering the well and ensuring a dry environment in the well.
[0031] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
