Description

Technical Field

[0001] This invention relates to the field of building crack sealing construction technology, and in particular to a construction method for sealing water seepage cracks in basement walls. Background Technology

[0002] Water seepage and cracks in basement walls are a common and challenging problem to solve. Due to the unique geographical location of basements, they are constantly affected by groundwater pressure and humidity, and coupled with construction quality issues, this makes the walls prone to water seepage and cracks. These cracks threaten the building's functionality, durability, and even structural safety.

[0003] Currently, the main methods for addressing this issue are as follows: Traditional cement mortar repair method: This method is simple to operate, but the effect is not ideal. Cement mortar tends to shrink after drying, which may create gaps between it and the wall, leading to secondary water seepage. For wide cracks or cracks with internal cavities, cement mortar is difficult to fill completely.

[0004] Chemical grouting: This method involves injecting grouting material into cracks using high-pressure equipment. The material expands and solidifies to form a waterproof layer. While this method provides good filling results, it requires strict selection and proportioning of the grouting material, and is quite difficult to implement.

[0005] Waterproof coating application: Suitable for fine cracks and smooth surfaces, but not effective for wide cracks or internal cavities.

[0006] Pre-embedded waterstop method: Waterstops are pre-embedded during wall construction to prevent water seepage from cracks. However, once the waterstop is damaged or displaced, it will lose its effectiveness.

[0007] Although the above methods can solve the problem of water seepage and cracks to some extent, they still have many shortcomings: Unstable repair results: Due to the influence of construction quality and environmental conditions, the effects of traditional cement mortar repair methods and waterproof coating methods are not stable, and secondary water seepage is prone to occur.

[0008] The construction is difficult: chemical grouting and pre-embedded waterstop methods require high-level construction equipment and operators, and the selection and proportioning of grouting materials are also challenging.

[0009] Limited applicability: Different repair methods are suitable for different types of cracks, but when dealing with complex cracks, the existing methods are often not satisfactory.

[0010] Poor durability: Some repair materials are prone to aging and cracking during long-term use, resulting in a decline in repair effectiveness.

[0011] Although there are various methods for sealing water seepage cracks in traditional basement walls, they generally face problems such as high construction difficulty, high cost, and unsatisfactory results. Summary of the Invention

[0030] like Figures 1-9 As shown, this application discloses a construction method for sealing water seepage cracks in basement walls, including the following steps: S1: Inspect the site, determine the location of the water seepage cracks, and mark them. S2: Create a 20mm pouring groove at the marked location of the water seepage crack on the wall 500mm; S3: Treat the area of ​​the pouring groove 20, including the removal of dust, dirt and loose material from the concrete surface, and rinse with clean water after treatment; S4: Apply cement-based penetrating crystalline waterproof coating inside the casting groove 20; S5: Fit the first cavity 1903 of the prefabricated water-proof sleeve 19 onto the first support flange 1804 of the first sealing plate 18, and cover the casting groove 20 on the wall 500 with the first sealing plate 18 through the auxiliary machine. S6: The waterproof and weather-resistant adhesive is poured for the first time into the space between the pouring groove 20 and the prefabricated waterproof sleeve 19 through the first pouring hole 1803 on the first sealing plate 18; S7: After the first pouring is completed, the first sealing plate 18 is detached from the first cavity 1903 of the precast water-proof sleeve 19 by the auxiliary machine; S8: Apply epoxy resin waterproof coating to the first cavity 1903. After the coating is completed, cover the first cavity 1903 of the prefabricated waterproof sleeve 19 with the second sealing plate 23. S9: The cement mortar mixture is poured into the first cavity 1903 for the second time through the second pouring hole 2303; S10: After the second pouring is completed, the second sealing plate 23 is removed by the auxiliary machine, and the sealing structure is leveled with the wall 500.

[0031] The method for sealing water seepage cracks in basement walls disclosed in this application involves, at the start of construction, precise surveying and marking of the water seepage cracks, followed by the creation of a pouring groove 20 at the crack location. The sealing operation mainly consists of two steps: First, using a first sealing plate 18 and a prefabricated waterproof sleeve 19, waterproof and weather-resistant adhesive is injected into the pouring groove 20 to initially seal the main body of the pouring groove 20 at the seepage point, forming the first protective layer; then, the first sealing plate 18 is removed and replaced with a second sealing plate 23, and concrete is poured into the first cavity 1903 of the prefabricated waterproof sleeve 19 to complete the second sealing of the remaining space, thus forming double protection. During the sealing process, waterproof materials... In terms of the choice between brushing and pouring, cement-based penetrating crystalline waterproof coatings can enhance the waterproofing effect by blocking the internal pores of the wall through crystallization; the waterproof and weather-resistant adhesive uses polyurethane, acrylic, or silicone materials, which are liquid before pouring and solidify after pouring to form a waterproof sealing layer. This poured waterproof sealing layer is the first protective layer. The material of the prefabricated waterproof sleeve 19 is the same as the pouring material of the waterproof and weather-resistant adhesive. Epoxy resin waterproof coating is applied to the first cavity 1903 of the prefabricated waterproof sleeve 19 to enhance its adhesion to the concrete protective layer formed by the internal poured cement mortar, thereby greatly improving the stability of the seal and comprehensively improving the waterproofing performance. Throughout the sealing process, when slotting and fixing the first sealing plate 18 and the second sealing plate 23, an auxiliary machine is used to limit and fix the electric drilling equipment and the first sealing plate 18 and the second sealing plate 23 of the sealing assembly 400. This achieves precise opening of the pouring groove 20, reduces the need to open other connecting holes or fixing holes near the pouring groove 20, better protects the structural integrity of the wall, reduces the frequency of subsequent maintenance, and ensures construction quality and speed.

[0032] The method for sealing cracks in basement walls that discloses this application constructs a robust double-layer protective barrier through two pours, combining waterproof and weather-resistant adhesive with concrete. This effectively curbs water seepage in the walls, significantly enhances the waterproof function of the walls, and improves the durability of the sealing layer. Furthermore, this method simplifies the construction process with the aid of an auxiliary machine, reduces the difficulty of manual operation, saves time and labor costs, and ensures construction accuracy, significantly optimizing the sealing effect on cracks in basement walls that are prone to water seepage.

[0033] As a preferred example of this application, the auxiliary machine includes: The frame assembly 100 includes a vertical rail assembly 1 and a base plate support 2, wherein the vertical rail assembly 1 is mounted and fixed on the base plate support 2. The slide rod assembly 200 is used to connect and fix the sealing assembly 400, and can drive the sealing assembly 400 to slide in the horizontal direction; The drive assembly 300 is used to drive the slide bar assembly 200 to slide vertically on the vertical rail assembly 1. The sealing assembly 400 includes a first sealing plate 18 or a second sealing plate 23.

[0034] This design discloses the structure of an auxiliary machine. A frame assembly 100, including a vertical rail assembly 1 and a base plate support 2, ensures the stability and load-bearing capacity of the auxiliary machine. A sliding rod assembly 200 connects to and secures the sealing assembly 400. It can slide the sealing assembly 400 horizontally, allowing the sealing plate to be easily moved to a designated position. This enables the first sealing plate 18 or the second sealing plate 23 to quickly and reliably seal the opening of the casting cavity during sealing. A drive assembly 300 is the power source for the auxiliary machine, driving the sliding rod assembly 200 to slide vertically on the vertical rail assembly 1. This allows for precise vertical adjustment of the sealing plate to meet different construction needs. This design significantly simplifies the construction process. Construction personnel no longer need to perform complex measurement and positioning work; they can simply operate the auxiliary machine to accurately place the sealing plate, saving time and reducing construction difficulty. In addition, the auxiliary machine improves construction safety. Since the sealing plate can be precisely moved and positioned by the auxiliary machine, construction workers do not need to operate manually in dangerous locations, thereby reducing the occurrence of safety accidents.

[0035] As a preferred example of this application, the vertical rail assembly 1 includes a first vertical rail 4 and a second vertical rail 5, which are vertically arranged. The base plate support 2 includes a first support plate 201, a second support plate 202, and a third support plate 203. The second support plate 202 is connected to the lower end of the first vertical rail 4 away from the second vertical rail 5, and the third support plate 203 is connected to the lower end of the second vertical rail 5 away from the first vertical rail 4. The first support plate 201 is connected between the first vertical rail 4 and the second vertical rail 5. As a specific example of this application, the first support plate 201 is used to connect and fix the drive assembly 300. The second support plate 202 and the third support plate 203 are symmetrically arranged on opposite sides of the first support plate 201. The second support plate 202 and the third support plate 203 are used to fix the frame assembly 100 to the ground or to other fixing devices to ensure that the frame assembly 100 remains fixed relative to the ground during use. The above-described configuration discloses a specific structure of a frame assembly. The frame assembly 100 consists of a vertical rail assembly 1, a base plate support 2, and a sliding rod assembly 200, ensuring the stability and flexibility of the construction process. The vertical rail assembly 1 is installed on the base plate support 2, providing solid support and ensuring effective sealing of water seepage cracks in the basement walls. The sliding rod assembly 200 is located between the first vertical rail 4 and the second vertical rail 5, and its position can be precisely adjusted by a motor to adapt to different walls and cracks, thereby simplifying the construction process and improving the accuracy and efficiency of sealing. By adjusting the sliding rod assembly 200, the sealing plate can be easily installed and moved without drilling holes in the wall, ensuring the safety and reliability of the sealing.

[0036] As a preferred example of this application, a first connecting rod 3 is provided at the upper end of the first vertical rail 4 and the second vertical rail 5. The first connecting rod 3, the first vertical rail 4, the second vertical rail 5, and the first support plate 201 of the base plate support 2 form a rectangular frame body. This design, by providing the first connecting rod 3 at the upper end of the first vertical rail 4 and the second vertical rail 5 for connection, makes it form a stable frame structure with the vertical rail assembly 1 and the base plate support 2, providing solid support for the sealing process, thereby effectively improving sealing efficiency and sealing quality. In addition, the setting of the first connecting rod 3 not only strengthens the overall integrity of the frame, but also greatly facilitates the hoisting, fixing, transportation, and storage of the frame assembly 100, improving the convenience and safety of construction.

[0037] As a preferred example of this application, the slide bar assembly 200 includes a first fixed slide bar 6, which includes a first sliding rod 8, a first horizontal rail 9, a second horizontal rail 10, and a first horizontal sliding motor 11. The first horizontal rail 9 is disposed on the first vertical rail 4, and the second horizontal rail 10 is disposed on the second vertical rail 5. The first sliding rod 8 is disposed between the first horizontal rail 9 and the second horizontal rail 10 and slides horizontally along the first horizontal rail 9 and the second horizontal rail 10 under the action of the first horizontal sliding motor 11. The first sliding rod 8 is fixedly connected to the sealing assembly 400. In the example of this application, when sealing the seepage cracks, when the drive assembly 300 drives the first fixed slide rod 6 to move to the vertical working position on the vertical rail assembly 1, the first horizontal sliding motor 11 drives the first sliding rod 8 to move along the first horizontal rail 9 and the second horizontal rail 10 on the left and right sides towards the side closer to the wall 500. The first sealing plate 18 or the second sealing plate 23 in the sealing assembly 400 moves together with the first sliding rod 8 until the pouring chamber is covered. Then the first horizontal sliding motor 11 locks the sealing assembly 400 relative to the wall 500 until the pouring is completed. Then the first horizontal sliding motor 11 drives the first sliding rod 8 to move away from the wall 500, thereby removing the sealing assembly 400.

[0038] The present invention discloses a structure of a sliding rod assembly 200, which enables precise movement of the sealing assembly in the horizontal and vertical directions through the structure of the first fixed sliding rod 6, allowing the sealing plate to quickly and accurately reach the designated position and cover the casting chamber. This design structure is ingenious and practical, improving construction efficiency and further enhancing the accuracy and stability of sealing. At the same time, it also makes the sealing process more automated and intelligent, reducing the complexity and uncertainty of manual operation.

[0039] As a preferred example of this application, the slide rod assembly 200 further includes a second fixed slide rod 7, which includes a second sliding rod 12, a third horizontal rail 13, a fourth horizontal rail 14, and a second horizontal sliding motor 15. The third horizontal rail 13 is disposed on the first vertical rail 4, and the fourth horizontal rail 14 is disposed on the second vertical rail 5. The second sliding rod 12 is disposed between the third horizontal rail 13 and the fourth horizontal rail 14 and slides horizontally along the third horizontal rail 13 and the fourth horizontal rail 14 under the action of the second horizontal sliding motor 15. The second sliding rod 12 is arranged parallel to the first sliding rod 8, and the second sliding rod 12 and the first sliding rod 8 are screwed to the upper and lower ends of the first sealing plate 18 or the second sealing plate 23.

[0040] This design discloses a slide bar assembly 200 structure comprising two sliding rods. This dual-slide bar design not only improves the stability of the sealing plate during movement but also enhances its positioning accuracy. Furthermore, the second sliding rod is arranged parallel to the first sliding rod, and both are connected to the upper and lower ends of the sealing plate, respectively. This structure further strengthens the stability of the sealing plate, effectively preventing swaying or displacement that may occur during construction, and improving the reliability of the sealing construction for water seepage cracks in basement walls.

[0041] As a preferred example of this application, the first fixed slide bar 6 and the second fixed slide bar 7 slide together on the vertical rail assembly 1 via the drive assembly 300, or the first fixed slide bar 6 and the second fixed slide bar 7 are driven independently by the first drive device 16 and the second drive device 17 in the drive assembly 300. As a specific example of this application, the drive assembly 300 includes a first drive device 16 and a second drive device 17. The first drive device 16 is used to drive the first fixed slide rod 6 to slide vertically on the vertical rail assembly 1, and the second drive device 17 is used to drive the second fixed slide rod 7 to slide vertically on the vertical rail assembly 1. In use, the vertical distance between the second sliding rod 12 and the first sliding rod 8 is first adjusted according to the installation dimensions of the first sealing plate 18 or the second sealing plate 23 to meet the installation requirements of various sealing assemblies 400 of different specifications. After the first sealing plate 18 or the second sealing plate 23 is installed and fixed with the second sliding rod 12 and the first sliding rod 8, the second sliding rod 12 and the first sliding rod 8 are driven to slide horizontally as a whole by the first horizontal sliding motor 11 and the second horizontal sliding motor 15, so as to realize the driving movement of the sealing assembly 400 towards or away from the wall 500.

[0042] This design discloses the specific driving scheme of the sliding rod assembly 200, realizing flexible driving of the first fixed sliding rod 6 and the second fixed sliding rod 7. It not only meets the installation requirements of various sealing components of different specifications, but also greatly improves the flexibility and adaptability of construction, enhances the convenience and efficiency of construction, and ensures the accuracy and reliability of sealing. It provides strong technical support for the sealing construction of water seepage cracks in basement walls.

[0043] As a preferred example of this application, the first sealing plate 18 includes a first sealing plate body 1801, on which a first connecting hole 1802 is provided. The first connecting hole 1802 is a threaded blind hole for connecting with the first sliding rod 8 or the second sliding rod 12 of the sliding rod assembly 200 by screws. A first supporting flange 1804 is provided on the first sealing plate body 1801. The first supporting flange 1804 and the first connecting hole 1802 are formed on two sides of the first sealing plate body 1801. A first pouring hole 1803 is provided on the first sealing plate body 1801 outside the first supporting flange 1804. The first pouring hole 1803 is used for the first pouring of the space between the pouring groove 20 and the prefabricated water-proof sleeve 19. This design discloses a specific structure of the first sealing plate 18. By adopting a blind hole design for the first connecting hole 1802 opened in the first sealing plate body 1801, it can be firmly connected to the sliding rod assembly, ensuring the stability and safety of the sealing plate. At the same time, the design of the first supporting flange 1804 on the first sealing plate body 1801 is used to support and fix the prefabricated water-proof sleeve 19 during the first pouring of the sealing. Combined with the position design of the first pouring hole 1803, it can accurately pour the first time into the space between the pouring groove 20 and the prefabricated water-proof sleeve 19, improving construction efficiency and ensuring pouring quality.

[0044] As a preferred example of this application, the first support flange 1804 is arranged in a circular shape, and multiple first pouring holes 1803 are provided. The multiple first pouring holes 1803 are evenly distributed in a circular shape at the outer circumferential position of the projected outline of the first support flange 1804 on the first sealing plate body 1801. As a specific example of this application, eight first pouring holes 1803 are provided, and the line connecting the center of two adjacent first pouring holes 1803 to the center of the first support flange 1804 forms a 45° angle. This design further optimizes the structure of the first sealing plate 18 by designing the first support flange 1804 as a ring shape. This not only enhances the overall structural strength of the first sealing plate and provides a stable support surface for the sealing operation, but also facilitates the reliable detachment of the first sealing plate 18 from the prefabricated water-proof sleeve 19 after the first sealing is completed. At the same time, multiple first pouring holes 1803 are evenly distributed in a circular shape on the first sealing plate body 1801, making the first pouring process more uniform and efficient, improving construction efficiency, and ensuring the uniformity of pouring quality, making the pouring process smoother and without dead corners.

[0045] As a preferred example of this application, a first through hole 1805 is provided on the inner side of the first support flange 1804. The first through hole 1805 penetrates the first sealing plate body 1801. Correspondingly, the prefabricated water-proof sleeve 19 includes a first bottom wall 1901 and a first side wall 1902. The first side wall 1902 surrounds one side of the first bottom wall 1901 and forms a first cavity 1903. The first side wall 1902 can be sleeved on the outer wall of the first support flange 1804, and at this time, the first bottom wall 1901 blocks the first through hole 1805. In the example of this application, the first through hole 1805 is designed as a through hole, which helps to use the first sealing plate 18 as a support and fixing structure for fixing the electric drill. This eliminates the need to replace the sealing component 400 when the drilling is completed. After removing the electric drill, the prefabricated waterproof sleeve 19 can be directly installed for sealing, simplifying the construction process and improving construction efficiency. At the same time, the structural design of the prefabricated waterproof sleeve 19 fits perfectly with the first sealing plate 18. The first side wall 1902 can be easily fitted onto the outer wall of the first support flange 1804, while the first bottom wall 1901 can effectively seal the first through hole 1805, ensuring the tightness and stability of the seal. This achieves functional diversification and construction efficiency, bringing substantial convenience and improvement to the sealing project of water seepage cracks in basement walls.

[0046] As a preferred example of this application, the second sealing plate 23 includes a second sealing plate body 2301, on which a second connecting hole 2302 and a second pouring hole 2303 are provided. The second connecting hole 2302 is used for threaded connection between the second sealing plate 23 and the first sliding rod 8 or the second sliding rod 12. The second connecting hole 2302 is a blind hole. The second pouring hole 2303 is used for the second sealing plate 23 to seal the outside of the first cavity 1903 and then to introduce cement mortar mixture into the first cavity 1903 for a second pouring.

[0047] This design discloses a specific structure for the second sealing plate 23, enabling it to slide vertically and horizontally in conjunction with the slide bar assembly 200 on the auxiliary machine. The connection is reliable, the positioning precise, and the structure reasonable, ensuring the uniformity and density of the pouring and improving the sealing effect. Furthermore, this design helps to further simplify the construction process and improve construction quality and efficiency.

[0048] In the example of this application, the cement mortar mixture poured in this second sealing structure has a cement to mortar weight ratio of 1:2 to 2.8, and the coating thickness of the cement-based penetrating crystalline waterproof coating is 1.2 mm to 1.7 mm, preferably 1.5 mm.

[0049] As a preferred example of this application, step S2 includes the following specific steps: S21: Connect the first connecting hole 1802 on the first sealing plate 18 to the first sliding rod 8 and the second sliding rod 12 in the auxiliary machine upper sliding rod assembly 200 with screws; S22: Fix the base plate support 2 of the frame assembly 100 relative to the ground, and make the first sealing plate 18 able to cover the marked position of the water seepage crack in S1. S23: Fix the electric drill used to open the casting groove 20 at the first through hole 1805 of the first sealing plate 18. Adjust the position of the first sealing plate 18 up and down and near and far according to the sliding rod assembly 200, change the position of the electric drill relative to the wall 500, and open the casting groove 20 on the wall 500 by adjusting the orientation angle of the electric drill.

[0050] This setup utilizes a first sealing plate on the auxiliary machine connected to a sliding rod assembly via screws to fix the base plate of the frame assembly relative to the ground, thereby achieving a stable connection and reliable support for the frame assembly 100. By cleverly utilizing the through hole on the first sealing plate to fix the electric drill, and adjusting the position and orientation of the electric drill according to the sliding rod assembly, a pouring groove can be precisely opened on the wall. This series of operations not only simplifies the construction process but also greatly improves construction accuracy and efficiency, enabling rapid and accurate treatment of water seepage cracks. In the example of this application, the electric drill structure and the installation structure of the first through hole 1805 are fixed using any existing connection method that achieves angle transformation. This connection structure is not an improvement of this application and will not be elaborated upon here.

[0051] In the example of this application, the casting groove 20 is generally rectangular in shape, and when the casting groove 20 is opened, a flared portion 21 is provided on its opening side. As a specific example of this application, the flared portion 21 is inclined from the inside to the outside. When the first sealing plate 18 covers the casting groove 20 for the first casting, a first sealing strip 22 is provided between the first sealing plate 18 and the wall 500. When the second sealing plate 23 covers the first cavity 1903 for the second casting, a second sealing strip 24 is provided between the second sealing plate 23 and the wall 500.

[0052] The design of the pouring groove in this example takes into account both the practicality of construction and the sealing effect. The rectangular groove shape facilitates construction and positioning. During pouring, a first sealing strip 22 and a second sealing strip 24 are respectively set between the first sealing plate 18 and the second sealing plate 23 and the wall 500. This further enhances the tightness of the sealing and ensures that the pouring material will not leak out, thereby improving the sealing effect.

[0053] As a preferred example of this application, step S5 includes the following specific steps: S51: Remove the electric drill from the first through hole 1805; S52: Apply a release agent to the outer surface of the first support flange 1804, and fit the first cavity 1903 of the prefabricated water-proof sleeve 19 onto the outer surface of the first support flange 1804. S53: A first sealing strip 22 is attached to the upper and lower ends of the first sealing plate 18 near the end position; S54: Apply epoxy resin waterproof coating to the outer surface of the first sidewall 1902 on the prefabricated waterproof sleeve 19; S55: The drive assembly 300 controls the first sliding rod 8 and the second sliding rod 12 to move up and down as a whole, so that the first sealing plate 18 connected by the first sliding rod 8 and the second sliding rod 12 is aligned with the pouring groove 20; S56: The first horizontal sliding motor 11 and the second horizontal sliding motor 15 drive the first sliding rod 8 and the second sliding rod 12 to slide horizontally along the side close to the wall 500 until the first sealing strip 22 is tightly sealed to the wall 500.

[0054] As a preferred example of this application, in step S6, the injection nozzle of the injection device is inserted into the first casting hole 1803 on the first sealing plate 18 to perform the first casting in the space between the casting groove 20 and the prefabricated water-proof sleeve 19, and the first sealing layer 600 is formed after molding.

[0055] As an example of this application, in step S6, when the injection device performs the first injection on the injection groove 20, the injection space is divided into 3 to 5 injections, and after each injection, hot air is introduced into the space through the first injection hole 1803 to pressurize it.

[0056] This setup, through scientifically designed steps and meticulous operation, discloses a specific procedure for the first pouring using an auxiliary machine. First, the electric drill is removed and a release agent is applied, facilitating subsequent operations. Next, a prefabricated waterproof sleeve 19 is fitted and a first sealing strip 22 is attached, enhancing the sealing performance. Applying epoxy resin waterproof coating to the outside of the prefabricated waterproof sleeve 19 further improves the waterproofing effect. Precise control of the drive component 300 and the horizontal sliding motor ensures that the first sealing plate 18 is accurately aligned and tightly adhered to the wall 500, guaranteeing sealing accuracy. The method of pouring in stages and introducing hot air for pressurization not only ensures the compactness of the pour but also effectively prevents voids and cracks. This series of rigorous and efficient steps significantly improves the sealing effect and construction quality.

[0057] In the example of this application, during the second pouring in step S9, the installation and sealing steps of the second sealing plate 23 are similar to those of the first sealing plate 18 in step S5, and will not be repeated here. After the second pouring in step S8, the second sealing layer 700 is formed in the first cavity 1903.

[0058] According to the construction method for sealing basement wall seepage cracks described in this invention, a sealing structure consisting of a first sealing layer 600, a prefabricated waterproof sleeve 19, and a second sealing layer 700 is formed by two pouring operations within the pouring groove 20. This method cleverly combines the advantages of each layer, resulting in a more outstanding sealing effect. The first sealing layer 600 and the second sealing layer 700 are located on the inner and outer sides of the prefabricated waterproof sleeve 19, respectively, forming double protection and greatly improving the reliability and durability of the sealing.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
