[0002] A sponge city refers to a mode of urban development that effectively controls rainwater runoff and achieves natural accumulation, natural infiltration, and natural purification by strengthening urban planning, construction, and management, giving full play to the absorption, storage, and slow-release functions of ecological systems such as buildings, roads, squares, green spaces, and water systems. It can adapt to environmental changes and respond to natural disasters caused by rainwater, just like a sponge, and has good elasticity. Therefore, it is also called a "water-elastic city." For this reason, a Chinese patent discloses a sponge city road drainage structure with application number 202020953347.9. The patent can collect rainwater to avoid waste of water resources, and then use the water resources in the water storage tank, thereby filtering rainwater, promoting the effective use of water resources, improving the urban ecological environment, facilitating rainwater infiltration, preventing road surface waterlogging, and also preventing the impact of vehicles on the road base.

[0030] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0031] 1. It is equipped with a drainage and anti-seepage mechanism. The drainage channel is opened at the bottom of the drainage curbstone, so that the accumulated water on the road surface can be discharged smoothly, which can quickly reduce the accumulated water on the road surface. The drainage curbstone serves as a curb and drainage channel, making the drainage channel more stable and not easy to be damaged, which provides great convenience for the city to absorb and relieve rainwater, prevents rainwater from penetrating and causing damage to the urban roadbed, and improves the service life of the urban roadbed. At the same time, the water filter frame and the filter inclined plate can be used to filter and intercept the accumulated water discharged on the road surface, which can effectively block the dead leaves, stones and other garbage on the road surface, so that they are always on the surface of the roadbed, making it more convenient for cleaning personnel to clean directly on the road surface, and playing a simple filtering role in the absorbed rainwater, reducing the workload for the subsequent reuse of rainwater;

[0032] The filter plate plays a role in preparatory drainage. When the filter inclined plate is blocked by garbage, it provides another channel for the normal discharge of accumulated water, so that the accumulated water can be discharged smoothly. At the same time, the filter inclined plate remains inclined, forming an inclined storage space in the middle of the water filter frame. Under the action of rainwater flow, impurities and garbage floating with the water flow are accumulated inside this storage space, and the inclined accumulation will generate force on each other, which also plays a certain aggregation role on impurities and garbage, so that the gap left between the top of the filter plate and the water filter frame will not be completely blocked, and then the water flow can continue to discharge downward when the filter inclined plate is blocked.

[0033] 2. The interception plate and the drainage gravel layer are used to further filter the discharged accumulated water. The remaining leaf impurities in the accumulated water remain on the surface of the interception plate, and the water flow in the drainage gravel layer needs to flow along the gaps in the gravel, which can effectively intercept the small particles in the accumulated water. The support mesh supports the drainage gravel layer to prevent it from falling off, providing multi-layer filtration and interception, effectively reducing impurities in the water flow, and providing convenience for the subsequent recycling of accumulated water.

[0034] 3. The driving motor drives the rotating disc and the driving column to rotate continuously, and then the driving connecting rod and the swing rod can be used to pull the moving rod to move back and forth, so that the connecting frame and the cleaning rod can swing left and right on the side of the drainage curbstone, and the impurities and garbage accumulated on one side of the water filter frame can be moved, thereby creating a certain flow channel for the drainage of accumulated water, promoting the normal discharge of water flow, and preventing the filter inclined plate from being blocked, resulting in a decrease in drainage efficiency and the inability to drain the accumulated water on the urban road surface in time during floods. In addition, the cleaning rod is in close contact with the surface of the water filter frame, which has a certain pressing and stabilizing effect on the water filter frame, thereby improving the stability of the water filter frame installation and preventing the water filter frame from shaking inside the drainage curbstone.

[0035] At the same time, the electric adjustment rod and the sealing plywood can be used to cover and seal one side of the sealing frame, so that the internal structure of the sealing frame will not be directly exposed to the external environment, which plays a protective role. When the sealing plywood is idle, it covers one side of the filter inclined plate to prevent dust from continuously adhering to and accumulating on the filter inclined plate during the idle process, and improves the integrity and aesthetics of the drainage curbstone. The height of the sealing plywood is adjusted according to the required drainage volume. When there is not much accumulated water, it is discharged directly through the bottom of the sealing plywood. During floods, the sealing plywood rises to expand the drainage channel.

[0036] 4. A supporting and stabilizing mechanism is provided, which uses the casting support column to support and stabilize the sidewalk, thereby creating a certain drainage channel under the sidewalk, so that the discharged water can be discharged smoothly without the need for pre-buried pipes and connections, which is more convenient to use. In addition, the width and space under the sidewalk are sufficient, which effectively improves the city's water absorption capacity. The left and right protective covers play a role in positioning the casting support columns, making the casting method more convenient and the positions between them can correspond correctly. The positioning columns and positioning holes correspond to each other, limiting the position of the left and right protective covers, so that they remain stable during the casting process and prevent errors in the top level caused by skew;

[0037] At the same time, the installation block is connected to the inside of the positioning frame, and the supporting diagonal rod plays an auxiliary supporting role for the bottom of the horizontal top plate. The support is at the side where the bottom end of the horizontal top plate contacts the casting support column, and works together with the casting support column to improve the support stability of the sidewalk, and prevent the sidewalk from collapsing and being damaged due to uneven force. The stabilizing block limits the reinforcing diagonal rod, and the reinforcing diagonal rod reinforces the supporting diagonal rod. The auxiliary support occupies a small space and will not affect drainage, making full use of all space, thereby improving the overall drainage capacity of the city.

[0038] 5. The L-shaped mounting block and the splicing block are connected to each other to improve the connectivity between the support channel and the right protective cover, making the installation of the support channel more stable. At the same time, the movable rod and the fitting block are tightly attached to the surface of the reinforcing cross bar to support and stabilize the reinforcing cross bar and the reinforcing vertical bar, thereby improving the stability of the support channel and the supporting vertical plate, and preventing the cushion layer from generating pressure on both sides after being subjected to road pressure, causing the support channel to be skewed and damaged.

[0039] In summary, by combining the drainage and anti-seepage mechanism with the support and stabilization mechanism, the drainage channel is expanded, the water absorption and drainage capacity of the sponge city is increased, and the drainage is hidden under the sidewalk while the sidewalk is supported and stabilized, and the curb is used for drainage, which improves the stability of the drainage channel and makes it less prone to damage. The drainage channel under the sidewalk is supported and stabilized in multiple directions, which improves the overall drainage stability. The support and stabilization structure also supports, stabilizes and isolates the cushion layer under the road surface from the side. When the accumulated water is discharged, it will not contact the bottom of the roadbed, preventing the cushion layer from being squeezed or damaged by water seepage. They work together to protect the entire roadbed and extend the service life of the roadbed. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0058] Example: Figure 1-11 As shown, the present invention provides a technical solution, a roadbed protection structure for preventing water seepage in a sponge city from infiltrating, comprising a foundation 1, a cushion layer 2 is laid on one end of the top of the foundation 1, an asphalt pavement 3 is laid on the top of the cushion layer 2, and a drainage and anti-seepage mechanism 4 is provided on one end of the top of the asphalt pavement 3;

[0059] The drainage and anti-seepage mechanism 4 includes a drainage curbstone 401;

[0060] One end of the top of the asphalt pavement 3 is fitted with a drainage curbstone 401, and a water filter frame 402 is symmetrically embedded in the interior of the drainage curbstone 401. The interior of the water filter frame 402 is fixedly connected with interception rods 403 at equal intervals. A filter inclined plate 404 is fixedly installed in the middle of the water filter frame 402, and a filter plate 405 is fixedly connected to the top of the filter inclined plate 404. The surface wall of the water filter frame 402 is connected to the inner wall of the drainage curbstone 401, and the top of the filter plate 405 is connected to the water filter frame 40 2, there is a gap between the top and bottom of the filter frame 402, one end of the filter frame 402 is fixedly connected to an L-shaped cleaning plate 406, a support mesh plate 407 is installed on one side of the bottom of the asphalt pavement 3, the top of the support mesh plate 407 is paved with a drainage gravel layer 408, and the top of the drainage gravel layer 408 is fitted with an interception plate 409. The top of the foundation 1 is located on one side of the cushion layer 2 and is fixedly installed with a support channel 410. The bottom end of the L-shaped cleaning plate 406 is flush with the top of the interception plate 409. The support channel 410 is located just below the drainage curb 401, and the support mesh plate 407 is fixedly embedded in the top inner part of the support channel 410. The drainage channel is opened at the bottom of the drainage curb 401, so that the accumulated water on the road surface can be discharged smoothly, which can quickly reduce the accumulated water on the road surface. The drainage curb 401 serves as a curb and a drainage channel, making the drainage channel more stable and not easy to be damaged, providing great convenience for the city to absorb and relieve rainwater, preventing rainwater from penetrating and causing damage to the urban roadbed, and improving the service life of the urban roadbed. At the same time, the water filter frame 402 and the filter inclined plate 404 can be used to filter and intercept the accumulated water discharged on the road surface, and can effectively block the dead leaves, stones and other garbage on the road surface, so that it is always on the roadbed surface, which is more convenient for cleaning personnel to clean directly on the road surface, and plays a simple filtration role in the absorbed rainwater, reducing the workload for the subsequent reuse of rainwater.

[0061] The filter plate 405 serves as a preliminary drainage channel. When the filter inclined plate 404 is clogged with garbage, it provides another channel for the normal drainage of the accumulated water, allowing the accumulated water to be drained smoothly. At the same time, the filter inclined plate 404 remains tilted, forming an inclined storage space in the middle of the water filter frame 402. Under the action of the flow of rainwater, impurities and garbage floating with the water flow are accumulated inside this storage space. The inclined accumulation will generate mutual force, which also has a certain aggregation effect on the impurities and garbage, so that the gap between the top of the filter plate 405 and the water filter frame 402 will not be completely blocked. Therefore, when the filter inclined plate 404 is blocked, the water flow can continue to drain downward.

[0062] The interception plate 409 and the drainage gravel layer 408 are used to further filter the discharged accumulated water. The remaining blade impurities in the accumulated water remain on the surface of the interception plate 409, and the water flow in the drainage gravel layer 408 needs to flow along the gaps between the gravel and sand, which can effectively intercept small particles in the accumulated water. The support mesh plate 407 supports the drainage gravel layer 408 to prevent it from falling off, providing multi-layer filtration and interception, effectively reducing impurities in the water flow, and providing convenience for the subsequent recycling of the accumulated water.

[0063] A limit block 411 is fixedly installed at one end of the bottom of the support channel 410, and a support vertical plate 412 is fitted on the surface of one end of the support channel 410. The bottom of the support vertical plate 412 is movably embedded in the interior of the limit block 411, and the support vertical plate 412 is located between the support channel 410 and the cushion layer 2;

[0064] One end of the top of the drainage curbstone 401 is fixed with convex blocks 413 at equal intervals, and the middle of one end of the drainage curbstone 401 is provided with drainage holes 414 at equal intervals.

[0065] A sealing frame 415 is fixedly installed on the top of the drainage curb 401, and a mounting seat 416 is fixedly installed inside the sealing frame 415. A moving rod 417 is movably installed in the middle of the mounting seat 416. Both ends of the moving rod 417 are fixedly connected to connecting rods 418. A connecting column 419 is fixedly installed at the end of one connecting rod 418. The middle part of the connecting column 419 is rotatably connected to a swing rod 420. A driving motor 421 is fixedly installed at one end of the sealing frame 415. The output shaft of the driving motor 421 is fixedly connected to the A rotating disc 422 is connected, and a driving column 423 is fixedly installed on the edge of one end surface of the rotating disc 422. The middle part of the driving column 423 is rotatably connected to a driving connecting rod 424. The middle part of the moving rod 417 is fixedly connected to a connecting frame 425. The bottom end of the connecting frame 425 is equidistantly fixedly connected to a cleaning rod 426. Electric adjustment rods 427 are symmetrically fixedly installed at both ends of the sealing frame 415. A sealing fitting plate 428 is fixedly connected between the bottom ends of the two electric adjustment rods 427. One end of the driving connecting rod 424 and the swing One end of the rod 420 is movably connected by a rotating shaft, and the cleaning rod 426 is closely attached to the surface of the drainage curb 401 and the water filter frame 402. The bottom end horizontal plane height of the sealing laminating plate 428 is higher than the top horizontal plane height of the asphalt pavement 3. The driving motor 421 drives the rotating disc 422 and the driving column 423 to rotate continuously, and then the driving connecting rod 424 and the swing rod 420 can be used to pull the moving rod 417 to reciprocate left and right, so that the connecting frame 425 and the cleaning rod 426 are located on the left and right side of the drainage curb 401. The swinging action moves the impurities and garbage accumulated on one side of the water filter frame 402, thereby creating a certain flow channel for the drainage of the accumulated water, promoting the normal drainage of the water flow, and preventing the filter inclined plate 404 from being blocked, which leads to a decrease in drainage efficiency and the inability to drain the accumulated water on the urban road surface in time during floods. In addition, the cleaning rod 426 is closely attached to the surface of the water filter frame 402, which has a certain pressing and stabilizing effect on the water filter frame 402, thereby improving the installation stability of the water filter frame 402 and preventing the water filter frame 402 from shaking inside the drainage curb 401;

[0066] At the same time, the electric adjustment rod 427 and the sealing plate 428 can be used to cover and seal one side of the sealing frame 415, so that the internal structure of the sealing frame 415 will not be directly exposed to the external environment, which plays a protective role. When the sealing plate 428 is idle, it covers one side of the filter inclined plate 404 to prevent dust from continuously adhering to and accumulating on the filter inclined plate 404 during the idle process, and improves the integrity and aesthetics of the drainage curbstone 401. The height of the sealing plate 428 can be adjusted according to the required drainage volume. When the accumulated water is not large, it is directly discharged through the bottom of the sealing plate 428. During floods, the sealing plate 428 rises to expand the drainage channel.

[0067] A supporting and stabilizing mechanism 5 is installed on the top of the foundation 1 at one side of the cushion layer 2;

[0068] The supporting and stabilizing mechanism 5 includes a filling layer 501;

A left protective cover 504 is equidistantly provided on one side of the top of the horizontal base plate 502. A right protective cover 505 is equidistantly provided on the other side of the top of the horizontal base plate 502. Positioning columns 506 are fixedly connected to the four corners of the bottom ends of the left and right protective covers 504 and 505.

The corresponding two left protective covers 504 and the right protective covers 505 are fixedly installed with a connecting plate 513. The middle part of the top of the connecting plate 513 is symmetrically fixed with a stable block 514. The top of the supporting top plate 511 fits the bottom end of the horizontal top plate 527. The bottom end of the reinforcing diagonal rod 512 is close to one end of the stable block 514. The cast support column 507 is used to support and stabilize the sidewalk below, thereby creating a certain drainage channel below the sidewalk. The discharged water can be discharged smoothly without the need for pre-buried pipes and connections, which makes it more convenient to use. In addition, the width and space under the sidewalk are sufficient, which effectively improves the city's water absorption capacity. The left protective cover 504 and the right protective cover 505 play a role in positioning the pouring support column 507. The pouring method is more convenient, and the positions between them can correspond correctly. The positioning columns 506 and the positioning holes 503 correspond to each other, limiting the left protective cover 504 and the right protective cover 505 to keep them stable during the pouring process and prevent errors in the top level caused by skew.

[0070] At the same time, the installation block 509 is clamped inside the positioning frame 508, and the supporting diagonal rod 510 plays an auxiliary supporting role for the bottom of the horizontal top plate 527. It is supported at the side position where the bottom end of the horizontal top plate 527 contacts the casting support column 507, and works together with the casting support column 507 to improve the support stability of the sidewalk, preventing the sidewalk from collapsing and being damaged due to uneven force. The stable block 514 limits the position of the reinforcing diagonal rod 512, and the reinforcing diagonal rod 512 reinforces the supporting diagonal rod 510. The auxiliary support occupies a small space and will not affect drainage, making full use of all space, thereby improving the overall drainage capacity of the city;

[0071] An upper connecting plate 515 is fixedly connected to the top of the right protective cover 505, and L-shaped mounting blocks 516 are symmetrically fixedly connected to both ends of the upper connecting plate 515. Splicing blocks 517 are symmetrically fixedly installed on the top of the two side walls inside the support channel 410. The positions of the two splicing blocks 517 and the two L-shaped mounting blocks 516 correspond to each other. The splicing blocks 517 are movably sleeved on the outside of the L-shaped mounting blocks 516. Reinforcement vertical rods 518 are equidistantly fixedly installed on one end of the support vertical plate 412 inside the support channel 410, and a reinforcement cross bar 519 is fixedly installed between the middle parts of the reinforcement vertical rods 518.

[0072] A lower connecting plate 520 is fixedly installed between the middle parts of the right protective cover 505, and a fixed frame 521 is fixedly installed at one end of the lower connecting plate 520 at an equidistant distance. A fixed rod 522 is fixedly installed at one end of the middle part of the fixed frame 521, and an extrusion pad 523 is fixedly bonded to the end of the fixed rod 522. A movable rod 524 is movably connected to the other end of the middle part of the fixed frame 521. Guide grooves 525 are symmetrically provided on both sides of the movable rod 524. A fitting block 526 is fixedly connected to the end of the movable rod 524. A horizontal top plate 527 is fitted between the top ends of the left protective cover 504 and the right protective cover 505. The two side walls inside the fixed frame 521 are symmetrically fixed. A clamping block is installed, which is movably clamped in the inside of the guide groove 525, and the fitting block 526 is tightly attached to the surface of the reinforcing cross bar 519. The L-shaped mounting block 516 and the splicing block 517 are clamped to each other, thereby improving the connectivity between the support channel 410 and the right protective cover 505, making the installation of the support channel 410 more stable. At the same time, the movable rod 524 and the fitting block 526 are tightly attached to the surface of the reinforcing cross bar 519 to firmly support the reinforcing cross bar 519 and the reinforcing vertical rod 518, thereby improving the stability of the support channel 410 and the supporting vertical plate 412, and preventing the cushion layer 2 from generating pressure on both sides due to road pressure, which may cause the support channel 410 to be skewed and damaged;

[0073] The top of the horizontal top plate 527 is paved with a sidewalk base layer 6 , and the top of the sidewalk base layer 6 is paved with sidewalk bricks 7 .

[0074] The working principle and use process of the present invention are as follows: First, a filling layer 501 is laid at one end of the top of the foundation 1, the top of the filling layer 501 is smoothed, and a horizontal base plate 502 is placed. The left protective cover 504 and the right protective cover 505 are taken and placed on both sides of the top of the horizontal base plate 502. The positioning columns 506 at the bottom ends of the left protective cover 504 and the right protective cover 505 are movably inserted into the interior of the positioning hole 503. The construction workers inject concrete into the interior of the left protective cover 504 and the right protective cover 505 to form a casting support column 507, the top of which is flush with the top of the left protective cover 504 and the right protective cover 505. The supporting diagonal rod 510 is taken, and the installation block 509 is inserted into the interior of the positioning frame 508, and The bottom end of the reinforcing diagonal rod 512 contacts the stabilizing block 514. At this time, the top of the supporting top plate 511 and the top of the pouring support column 507 are at the same horizontal plane height. The horizontal top plate 527 is placed on the top of the pouring support column 507 and the supporting top plate 511. Subsequently, the sidewalk base 6 and the sidewalk bricks 7 are laid in sequence. The pouring support column 507, the left protective cover 504 and the right protective cover 505 form a certain space under the sidewalk to meet the drainage needs without occupying the original space. The sidewalk is staggeredly supported by the pouring support column 507, the supporting top plate 511, the supporting diagonal rod 510 and other structures, which improves the stability of the sidewalk and prevents the sidewalk from deformation and collapse after being compressed.

[0075] Then, the construction workers take the support channel 410 and place it on the top of the foundation 1, and on one side of the right protective cover 505. When the support channel 410 falls, the inner splicing block 517 is sleeved on the L-shaped mounting block 516, which improves the connection strength between the right protective cover 505 and the right protective cover 505. In addition, the reinforcing cross bar 519 on the inner side of the support channel 410 will contact the fitting block 526 during the falling process, so that the movable rod 524 is tightly fitted with the extrusion pad 523. The movable rod 524 firmly supports the reinforcing crossbar 519 and the reinforcing vertical rod 518, thereby improving the stability of the support channel 410. The support vertical plate 412 is attached to one end surface of the support channel 410, and its bottom is embedded in the limit block 411. Then, when paving the road surface, the cushion layer 2 will be blocked by the support vertical plate 412, and the asphalt pavement 3 is poured on the surface of the cushion layer 2. After the support vertical plate 412 and the support channel 410 are supported, the cushion layer 2 can be effectively prevented from being squeezed and deformed toward the edge.

[0076] A portion of the sidewalk base 6 extends to the top of the support channel 410. The drainage curbstone 401 is placed on the surface of the sidewalk base 6 above the support channel 410. The supporting mesh plate 407 is fixed to the top of the support channel 410, and the drainage gravel layer 408 is piled on its surface. The interception plate 409 is laid flat on the top of the drainage gravel layer 408. The water filter frame 402 is inserted into the drainage curbstone 401. The cleaning rod 426 is always in close contact with the surface of the end of the water filter frame 402 to prevent it from shaking. The L-shaped cleaning plate 406 is inserted into the drainage curbstone 401 and is located on one side of the top of the interception plate 409. In clear weather, the sealing plate 428 covers one end surface of the drainage curbstone 401 to cover the water filter frame 402, and a certain distance is left between the bottom end of the sealing plate 428 and the surface of the asphalt pavement 3.

[0077] When it rains in a city, rainwater falls on the asphalt pavement 3 and may flow toward the edge. Based on the amount of rainfall, if the rainfall is light, the rainwater may flow through the gap at the bottom of the sealing laminating plate 428 into the interior of the drainage curbstone 401. The rainwater then passes through the filtering inclined plate 404, the intercepting plate 409, the drainage gravel layer 408, and the supporting mesh plate 407 in sequence, playing a multi-layer filtering role for the discharged rainwater, intercepting impurities and garbage of different sizes in the rainwater in turn, and finally being discharged into the space below the sidewalk base 6 through the supporting channel 410, so that the rainwater is collected and discharged.

[0078] If the rainfall is heavy, the electric adjustment rod 427 can drive the sealing laminating plate 428 to rise, increasing the space for rainwater to flow and discharge, so that rainwater can be quickly discharged from the inside of the drainage curb 401. At this time, the water flow increases, which can increase the discharge speed of road surface water. Impurities and garbage in the water flow accumulate on one side of the filter inclined plate 404. The filter inclined plate 404 is covered by garbage, which affects the penetration of water flow. However, there is a gap between the top of the filter plate 405 and the water filter frame 402, so that some rainwater can flow through this gap, realizing normal drainage of rainwater.

[0079] If heavy rain and flooding occur in the city, the driving motor 421 is started, driving the rotating disc 422 to rotate continuously, and the driving column 423 pulls the swing rod 420 to move through the driving connecting rod 424, so that the moving rod 417 moves back and forth along the mounting seat 416, pulling the connecting frame 425 and the cleaning rod 426 to move synchronously. When the cleaning rod 426 moves, it plays a role in moving the impurities and garbage accumulated on one side of the filtering inclined plate 404, thereby providing a certain vacant area in the accumulated and blocked garbage so that rainwater can be discharged smoothly. Multi-level control of drainage status is achieved according to the urban environment, making urban drainage more intelligent and reducing energy consumption to a certain extent.

[0080] At the same time, rainwater will fall on the sidewalk bricks 7 and flow along their surface. The sidewalk bricks 7 near the drainage curbstone 401 are tightly fitted with the protrusions 413, so that there is a certain gap between the sidewalk bricks 7 and the drainage curbstone 401. The flowing rainwater will flow through the gap and the drainage holes 414 into the interior of the drainage curbstone 401 and be discharged together with the rainwater discharged from the road surface.

[0081] The garbage and impurities are intercepted on one side of the water filter frame 402, which is convenient for subsequent staff to clean up on the roadside. The smaller garbage intercepted on the top of the interception plate 409 can be subsequently pulled out by pulling out the water filter frame 402, and the L-shaped cleaning plate 406 moves along with it to scrape out the garbage remaining on the top of the interception plate 409, making it easier to clean.

[0082] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
