Description

Technical Field

[0001] The present invention relates to the field of vibration isolation trench construction, and particularly to a construction device and a construction method for a soft-filled vibration isolation trench. Background Art

[0002] Vibrations caused by various building or road construction and traffic vibrations will not only have an adverse impact on the surrounding environment, but also pose a threat to the safety of surrounding structures, underground facilities, and related equipment and instruments. Currently, using filled trenches is an effective vibration isolation measure. Soft-filled trenches (such as rubber and polyethylene foam filled trenches) can effectively prevent waves from transmitting and diffracting due to their low elastic modulus, have a good effect on absorbing and dispersing vibration energy, and have excellent vibration isolation effects. However, the following problems still exist in the construction of such vibration isolation measures: Soft-filled trenches need to be pre-excavated into grooves by machinery or manually. Especially in soft soil areas, due to the poor stability of the trench sidewalls, it is necessary to excavate stepped slopes. After the trench is excavated, flexible filling materials such as rubber sand are filled. The construction process lacks a fast and efficient construction device, resulting in problems such as low construction efficiency, high construction costs, and long time-consuming backfilling material processes in the construction process of soft-filled trenches.

[0003] A static pressure type flexible vibration isolation airbag inserting machine and a construction method are disclosed in a Chinese patent (publication number CN11526007B, publication date September 30, 2022). Using the inserting plate as a conveying channel, after the inserting plate is pressed into the ground, the airbag is sent into the groove formed by the inserting plate, and the vibration isolation airbag can be directly placed into the area where vibration isolation is required. The two sides of the airbag are folded, and after inflation, the two sides stretch and fit together, enabling continuous operation and seamless docking between airbags; it uses vibration isolation airbags to form the required vibration isolation trench, but it is not suitable for the scenario of backfilling with flexible filling materials to establish a vibration isolation trench. Flexible filling materials are mostly in granular or powder form, which are inconvenient to be conveyed through the inserting plate. Moreover, compared with airbags, flexible materials in granular or powder form require a higher filling density to meet the vibration isolation requirements. Summary of the Invention

[0004] The object of the present invention is to address the defects existing in the prior art, and provide a construction device and a construction method for a soft-filled vibration isolation trench. An inserting plate with a boot is used to press down to form a groove. The boot can block or open the bottom end of the filler channel by rotating. After the inserting plate presses down to form a groove, flexible filling materials can be directly filled into the filler channel inside the inserting plate. After the filler channel is filled, the inserting plate is lifted, and the boots on both sides of the bottom open, so that the filler remains inside the trench, realizing the one-time forming of the vibration isolation filling trench, avoiding problems such as trench collapse and excavation of stepped slopes, reducing the construction working surface, reducing the engineering quantity, reducing the construction difficulty, especially suitable for construction in narrow spaces, and greatly shortening the construction period.

[0005] The first object of the present invention is to provide a construction device for a soft-filled vibration isolation trench, adopting the following solutions:

[0006] It includes:

[0007] A static press, including a plug board capable of moving vertically. A filler channel with both ends communicating is provided inside the plug board. One end of the plug board facing the ground is rotatably connected with a protective boot, and the protective boot is configured to block or open the bottom end of the filler channel by rotation;

[0008] A counterweight, arranged on the static press. A storage bin is provided on the counterweight. The discharge port of the storage bin is communicated with a material conveying guide groove, and the material conveying guide groove is configured to communicate with the top end of the filler channel to convey the filler into the filler channel.

[0009] Further, the static press further includes a driving element, and the driving element is connected to the plug board through a transmission mechanism to drive the plug board to move vertically.

[0010] Further, the transmission mechanism includes transmission cross beams respectively connected to both sides of the plug board and a transmission chain connecting the transmission cross beams. A support truss is provided on the static press. One end of the transmission chain is rotatably installed on the support truss, and the other end is connected to the driving element. The driving element drives the rotating chain to rotate to drive the plug board to move vertically through the transmission cross beam.

[0011] Further, the static press is provided with limiting rollers on both sides of the movement path of the plug board. The limiting rollers abut against the side surface of the plug board, and the limiting rollers on both sides jointly maintain the orientation of the plug board.

[0012] Further, there are two relatively distributed protective boots, which are symmetrically installed on the plug board with the axis of the filler channel as the reference line. The protective boots are rotatably connected to the plug board through connecting pins and pin holes.

[0013] Further, the rotation axis of the protective boot is parallel to the width direction of the plug board. After the two protective boots are joined together to block the filler channel, the end of the protective boot away from the plug board forms a tip for piercing the coating. The two protective boots are configured to separate under the action of the gravity of the filler inside the filler channel to open the bottom end of the filler channel.

[0014] Further, the storage bin includes storage bin bodies distributed on both sides of the plug board. The storage bin bodies are inclined surfaces. An opening is provided at the bottom end of the inclined surface on the side surface of the storage bin body. The opening is butted against the material conveying guide groove, and a sliding vertical plate for opening or blocking the opening is provided.

[0015] Further, the material conveying guide groove is inclinedly distributed to connect the storage bin bodies on both sides of the plug board and communicate with the filler channel.

[0016] The second object of the present invention is to provide a construction method for the construction device of the soft-filled vibration isolation trench as described in the first object, including:

[0017] The static press enters the construction position of the vibration isolation trench, and adjusts its position so that the bottom of the insertion plate corresponds to the marked line of the vibration isolation trench;

[0018] Drive the insertion plate to move vertically so that the insertion plate is inserted into the formation to a set depth;

[0019] After the insertion plate reaches the set depth, the material conveying chute is connected to the top of the packing channel, so that the packing in the silo enters the packing channel through the material conveying chute;

[0020] The insertion plate is lifted upwards. The protective boots at the bottom of the insertion plate rotate under the action of the gravity of the packing, so that the bottom of the packing channel is opened, and the packing falls into the groove formed by the insertion plate. As the insertion plate is lifted upwards, the packing continuously fills the groove until the insertion plate is completely lifted out of the formation, and the packing fills the groove to form a vibration isolation trench.

[0021] Further, when the insertion plate is lifted upwards, the groove is vibrated through the packing channel to fill it densely.

[0022] Compared with the prior art, the advantages and positive effects of the present invention are:

[0023] Aiming at the problem that the current flexible filling material is inconvenient to fill into the groove to form a vibration isolation trench, an insertion plate with protective boots is used to press down to form a groove. The protective boots can rotate to block or open the bottom end of the packing channel. After the insertion plate presses down to form a groove, the flexible filling material is filled into the packing channel in the insertion plate by using the silo. After the packing channel is filled, the insertion plate is lifted upwards, and the protective boots on both sides of the bottom open, and then the packing remains inside the groove, realizing the one-time forming of the vibration isolation filling trench, avoiding problems such as groove collapse and excavation of stepped slopes, reducing the construction operation surface, reducing the engineering quantity, reducing the construction difficulty, especially suitable for construction in narrow spaces, and greatly shortening the construction period.

[0024] The silo bodies are distributed on both sides of the insertion plate, and can convey the packing into the insertion plate from both sides respectively, and can dredge the blockage from the other silo body when the blockage occurs during the conveying process of one-sided silo body. The bottom of the silo body is inclinedly distributed, and the internal packing can be smoothly filled into the insertion plate. The packing temporarily stored in the silo body can be used as auxiliary counterweight to improve the stability during the operation of the static press.

[0025] The rotation axis of the protective boots is distributed along the width direction of the insertion plate rather than the thickness direction. The space occupied by the opening and closing of the protective boots is small, so that the protective boots can be rotated and opened after the insertion plate is lifted upwards by a small height. The bottom groove space not covered by the insertion plate caused by the lifting is small, avoiding the problem of the bottom groove collapse caused by the higher lifting of the insertion plate, improving the stability before filling the groove with the packing, and ensuring the density after filling the packing.

Detailed implementation manners

[0032] Embodiment 1

[0033] In a typical embodiment of the present invention, as Figures 1-4 shown, a soft-fill vibration isolation trench construction device is provided.

[0034] The existing static pressure type flexible vibration isolation airbag plug board machine is not applicable to the scenario of backfilling with flexible filling materials to establish a vibration isolation trench. For example, it is inconvenient to convey flexible filling materials (mostly in granular or powdery form) through the plug board. Based on this, this embodiment provides a soft-fill vibration isolation trench construction device. The plug board 1 with a boot 16 is used to press the groove. The boot 16 can block or open the bottom end of the filler channel by rotating. After the plug board 1 presses the groove, the silo 3 is used to fill the flexible filling materials into the filler channel in the plug board 1. Using the filler channel as a constraint and a channel, the scattering of the flexible filling materials is avoided. After the filler channel is filled, the plug board 1 is lifted, and the boots 16 on both sides of the bottom open, and then the filler gradually falls and remains inside the trench, realizing the one-time forming of the vibration isolation filling trench.

[0035] See Figures 1-4As shown in the figure, the soft-filled vibration isolation trench construction device mainly includes a static press 2 and a counterweight 5. The core component of the static press 2 is a plugboard 1, which can move vertically downward and penetrate into the soil layer. After the plugboard 1 is pulled out, a trench is formed at its penetration position, and the required vibration isolation trench is formed by filling the trench with filler. The filler in this embodiment is a flexible filling material. In other alternative embodiments, other forms of fillers can also be used, such as polymer filling materials, non-metallic filling materials, etc. To facilitate the transportation of the filler, a filler channel communicating at both ends is provided inside the plugboard 1, which serves as the transportation channel for the flexible filling material and solves the problem of transporting the flexible filling material.

[0036] To facilitate the penetration of the plugboard 1 into the soil layer and control the blocking and opening of the filler channel, a protective boot 16 is installed at one end of the plugboard 1. Specifically, a filler channel is formed inside the plugboard body 11. A protective boot 16 is installed at one end of the plugboard body 11. The protective boot 16 and the plugboard body 11 together form the plugboard 1. The protective boot 16 is rotatably connected to the end of the plugboard 1 facing the ground and is configured to block or open the bottom end of the filler channel by rotation. During the process of the plugboard 1 pressing down to form a groove, the protective boot 16 blocks the bottom end of the filler channel, reducing the resistance when inserting into the soil layer and preventing the material from leaking out during the downward pressing of the plugboard 1; when the plugboard 1 is pressed down in place and the filler channel is filled with the flexible filling material, the protective boot 16 opens, allowing the filler to remain inside the trench, realizing the one-time forming of the vibration isolation filling trench and avoiding problems such as trench collapse.

[0037] The counterweight 5 is arranged on the static press 2 to improve the stability of the static press 2. In addition, a material bin 3 is also provided on the counterweight 5 for storing the flexible filling material. The discharge port of the material bin 3 is connected to a material conveying guide groove 31, and the material conveying guide groove 31 is configured to be connected to the top end of the filler channel to convey the filler into the filler channel.

[0038] The material bin 3 can temporarily store the filler. After the plugboard 1 is inserted into the soil layer in place, the material bin 3 can be connected to the filler channel inside the plugboard 1 through the material conveying guide groove 31, so as to provide a stable source of flexible filling material for the filler channel, ensure that the filling material can smoothly enter the filler channel inside the plugboard 1, and then realize the filling construction of the vibration isolation trench.

[0039] As Figure 3 and Figure 4As shown in the figure, the static press 2 includes a driving element, which is connected to the plug board 1 through a transmission mechanism to drive the plug board 1 to move vertically. The driving element provides power for the plug board 1. The driving element can adopt power output elements such as motors, engines, and motors, which solves the problem of the power source for the downward pressing and upward lifting operations of the plug board 1. As a power source, the driving element can convert external energy into the power to move the plug board 1, providing a basis for the operation of the entire construction device. It generates power so that the plug board 1 can overcome the soil layer resistance and press downward, and can lift the plug board 1 from the ground, ensuring the operability and continuity of the construction process.

[0040] The automatic movement of the plug board 1 is realized, the construction efficiency is improved, the limitations of manual operation are avoided, the construction device has stronger working ability and adaptability, and it can complete the construction tasks of vibration isolation trenches under different depths and different geological conditions more stably.

[0041] The transmission mechanism includes transmission crossbeams 12 respectively connected to both sides of the plug board 1 and a transmission chain 6 connecting the transmission crossbeams 12. A support truss 4 is provided on the static press 2. One end of the transmission chain 6 is rotatably installed on the support truss 4, and the other end is connected to the driving element. The driving element drives the rotating chain to rotate to drive the plug board 1 to move vertically through the transmission crossbeam 12. The problem of how to effectively transmit the power of the driving element to the plug board 1 is solved.

[0042] Since the plug board 1 requires stable and accurate power transmission during vertical movement, a single connection method may not meet its movement requirements, and problems such as unstable power transmission and low transmission efficiency are likely to occur. The transmission crossbeam 12 connects the plug board 1 to the transmission chain 6, so that the plug board 1 can obtain power through the transmission chain 6. The support truss 4 provides a stable rotating support for the transmission chain 6, ensuring the stability of the rotation of the transmission chain 6. The driving element drives the transmission chain 6 to rotate, and the transmission chain 6 then evenly transmits the power to the plug board 1 through the transmission crossbeam 12, realizing the smooth vertical movement of the plug board 1. This makes the power transmission more reliable and uniform, avoiding jamming and instability during the power transmission process, and ensuring the accuracy and smoothness of the movement of the plug board 1.

[0043] It ensures the accuracy and stability of the vertical movement of the plug board 1, enables the plug board 1 to press downward at a stable speed and direction during the trench forming process, avoids the movement deviation of the plug board 1 caused by power transmission problems, improves the quality and efficiency of trench forming, and helps to ensure the dimensional accuracy and shape regularity of the vibration isolation trench.

[0044] During the vertical movement of the plug board 1, problems such as the deviation, shaking or orientation change of the plug board 1 may occur, which will lead to inaccurate trench forming positions and affect the construction quality of the vibration isolation trench. For example Figure 4As shown, in this embodiment, the limiting roller 22 is to solve the positioning and guiding problems of the plug board 1. The static press 2 is provided with limiting rollers 22 on both sides of the movement path of the plug board 1. The limiting rollers 22 abut against the side surface of the plug board 1, and the limiting rollers 22 on both sides jointly maintain the orientation of the plug board 1.

[0045] The limiting rollers 22 on both sides abut against the side surface of the plug board 1, forming a constraint on the plug board 1, so that it always remains on the predetermined movement path during the movement process. Through the contact with the side surface of the plug board 1, lateral support and guidance are provided for the plug board 1. No matter what kind of lateral force the plug board 1 receives, the limiting rollers 22 can ensure that its orientation remains unchanged, avoiding the influence of the deviation of the plug board 1 on the perpendicularity and shape of the groove. The construction accuracy of the vibration isolation trench is improved, the perpendicularity and shape accuracy of the trench are ensured, the accuracy of the trench forming position is guaranteed, thus providing a good foundation for the subsequent vibration isolation construction, reducing the construction error caused by the position deviation of the plug board 1, and improving the construction quality and stability.

[0046] In order to realize the plugging and opening operations of the packing channel bottom end by the protective boot 16, a reliable and flexible connection method is required. In this embodiment, as Figure 1 and Figure 2 shown, two protective boots 16 are provided and are symmetrically installed on the plug board 1 with the axis of the packing channel as the reference line. The protective boots 16 are rotationally connected to the plug board 1 through the connecting pin 14 and the pin holes.

[0047] Specifically, the two protective boots 16 are symmetrically installed on the plug board 1. With the axis of the packing channel as the reference line, it is ensured that during the plugging and opening operations, the forces on the two protective boots 16 on both sides are uniform and the actions are synchronous, ensuring that the bottom end of the packing channel can be evenly plugged or opened. Among them, the plug board 1 is provided with plug board pin holes 13, and the protective boots 16 are provided with protective boot pin holes 15. The connecting pin 14 passes through the coaxially distributed protective boot pin holes 15 and plug board pin holes 13 to realize the rotational connection between the protective boots 16 and the plug board 1. The connection method of the connecting pin 14 and the pin holes enables the protective boots 16 to rotate flexibly around the pin holes, realizing the rotational connection between the protective boots 16 and the plug board 1, and providing a structural basis for the opening and closing actions of the protective boots 16.

[0048] It ensures the reliable action of the protective boots 16 during the construction process, makes the opening and closing operations of the protective boots 16 more stable and consistent, helps to improve the reliability and stability of the vibration isolation trench construction, and prevents packing leakage or other construction problems caused by inconsistent actions of the protective boots 16.

[0049] When the plug board 1 is pressed down, the protective boot 16 needs to be able to easily penetrate the formation, and after the filling is completed, the bottom end of the filling channel needs to be automatically opened. At the same time, it is necessary to consider how to simplify the operation steps of the protective boot 16 and avoid complex driving and control structures. In this regard, the rotation axis of the protective boot 16 is parallel to the width direction of the plug board 1. After the two protective boots 16 are combined to block the filling channel, the end of the protective boot 16 away from the plug board 1 forms a tip for penetrating the coating. The two protective boots 16 are configured to separate under the action of the gravity of the filling material inside the filling channel to open the bottom end of the filling channel.

[0050] The rotation axis of the protective boot 16 is parallel to the width direction of the plug board 1, making the rotation of the protective boot 16 more in line with the mechanical principle and smoother. The tip design enables the protective boot 16 to penetrate the formation more effectively when the plug board 1 is pressed down, reducing the pressing resistance. The gravity of the filling material inside the filling channel is used to separate the protective boots 16, realizing an automatic control mechanism, avoiding additional power sources or complex control mechanisms. When the filling channel is filled with filling material and the plug board 1 is lifted to provide space for the protective boot 16 to open, under the action of gravity, the protective boot 16 automatically opens to realize the discharging function of the filling material.

[0051] On the other hand, the rotation axis of the protective boot 16 is distributed along the width direction rather than the thickness direction of the plug board 1. The space occupied by the opening and closing of the protective boot 16 is small, enabling the protective boot 16 to be rotated and opened after the plug board 1 is lifted by a small height. The bottom groove space not covered by the plug board 1 generated by the lifting is small, avoiding the problem of the collapse of the bottom groove caused by the high lifting of the plug board 1, improving the stability before filling the groove with filling material, and ensuring the compactness after filling the filling material.

[0052] Generally speaking, through the setting of the protective boot 16, the efficiency of pressing down the plug board 1 is improved, the complexity of the construction equipment is reduced, the equipment cost and maintenance cost are lowered, and at the same time, the automatic discharging function is realized, improving the construction efficiency and making the construction operation more concise and efficient.

[0053] In order to ensure that the flexible filling material can smoothly enter the material conveying guide groove 31 and be conveyed to the filling channel, it is necessary to design a reasonable silo 3 structure, and at the same time, it is necessary to solve the problem of how to control the filling material conveying volume to avoid waste or insufficient conveying of the material. In this regard, the silo 3 includes silo bodies 34 distributed on both sides of the plug board 1. The silo bodies 34 are inclined planes. An opening is provided at the bottom end of the side surface of the silo body 34. The opening is docked with the material conveying guide groove 31, and a sliding vertical plate 32 that cooperates to open or block the opening is provided.

[0054] Among them, the silo body 34 is designed with an inclined surface, so that the vertical section of the silo body 34 is trapezoidal. The inclined surface at the bottom of the silo body 34 is the inclined waist of the trapezoid. Utilizing the gravity of the flexible filling material, it can flow naturally towards the opening at the bottom of the inclined surface, facilitating the material to enter the material conveying chute 31 and improving the smoothness of material conveyance.

[0055] The overall material conveying chute 31 is inclined and is 4 cm away from the plugboard 1. The flexible filling material can enter the filling channel of the plugboard 1 along the material conveying chute 31. A sliding vertical plate 32 and a hydraulic device 33 are arranged at the connection between the material conveying chute 31 and the silo body 34 to form a control switch. The sliding vertical plate 32 slides up and down through the hydraulic device 33 to control the conveyance of the flexible filling material. The sliding vertical plate 32 at the opening can open or close the opening as needed to achieve precise control of material conveyance. By adjusting the position of the sliding vertical plate 32, the flow rate of the filling material can be flexibly controlled to ensure that the conveyance volume meets the construction requirements.

[0056] In addition, the hydraulic device 33 can also adopt linear drive components such as electric push rods and cylinder push rods to realize the sliding drive and position adjustment of the sliding vertical plate 32. Utilizing the silo 3 ensures the stable supply and conveyance of the flexible filling material, improves the efficiency and controllability of material conveyance, avoids construction problems caused by unstable material supply or excessive or too small flow rate, and ensures the continuity and high efficiency of the construction process.

[0057] The material conveying chute 31 is inclinedly distributed to connect the silo bodies 34 on both sides of the plugboard 1 to communicate the filling channels. The inclined distribution of the material conveying chute 31 makes full use of the gravitational potential energy, enabling the material flowing out of the silo 3 to smoothly flow into the filling channel under the action of gravity, reducing the resistance during material conveyance, and ensuring that the material can be continuously and smoothly conveyed from the silo 3 to the filling channel.

[0058] Such as Figure 1 and Figure 4 As shown, the silo bodies 34 are distributed on both sides of the plugboard 1, capable of conveying filling materials into the plugboard 1 from both sides respectively, and capable of unclogging when a blockage occurs during the conveyance of the unilateral silo body 34. The bottom of the silo body 34 is inclinedly distributed, and the internal filling material can be smoothly filled into the plugboard 1. The filling material temporarily stored in the silo body 34 can serve as the auxiliary counterweight 5 to enhance the stability during the operation of the static press 2.

[0059] Embodiment 2

[0060] In another typical implementation manner of the present invention, as Figures 1-4 shown, a construction method of a soft filling vibration isolation trench construction device is given, using the soft filling vibration isolation trench construction device as in Embodiment 1.

[0061] A construction method of a soft filling vibration isolation trench construction device includes:

[0062] The static press 2 enters the construction position of the vibration isolation trench, and adjusts the position so that the bottom of the insertion plate 1 corresponds to the marked line of the vibration isolation trench;

[0063] Drive the insertion plate 1 to move vertically so that the insertion plate 1 is inserted into the formation to a set depth;

[0064] After the insertion plate 1 reaches the set depth, the material conveying chute 31 is connected to the top end of the filling channel, so that the filling material in the silo 3 enters the filling channel through the material conveying chute 31;

[0065] The insertion plate 1 is lifted. The protective boot 16 at the bottom of the insertion plate 1 rotates under the action of the gravity of the filling material, so that the bottom of the filling channel is opened, and the filling material falls into the trench formed by the insertion plate 1. As the insertion plate 1 is lifted, the filling material continuously fills the trench until the insertion plate 1 is completely lifted from the formation, and the filling material fills the trench to form a vibration isolation trench.

[0066] A systematic and orderly construction process is provided for backfilling with a flexible filling material to establish a vibration isolation trench, solving the problem of how to efficiently and accurately complete the construction of the vibration isolation trench by using a soft-filled vibration isolation trench construction device, and ensuring that the construction process meets the characteristics of the flexible material and the quality requirements of the vibration isolation trench. The standardized process of soft-filled vibration isolation trench construction is realized, the construction efficiency is improved, the accuracy of the position and depth of the vibration isolation trench is guaranteed, the construction process of establishing the vibration isolation trench with a flexible filling material is made more controllable, which helps to ensure the quality of the vibration isolation trench and the vibration isolation effect.

[0067] When the insertion plate 1 is lifted, the trench is vibrated through the filling channel to fill it densely. During the lifting process of the insertion plate 1, the filling channel is used as a way for vibration to vibrate the filling material in the trench, so that the filling material particles are arranged more closely, reducing voids and increasing the density. There is no need for additional equipment for vibration operation, which simplifies the construction process. At the same time, the vibration function is realized by using the existing structure, improving the utilization rate of the equipment. It meets the requirements of the flexible filling material for filling density, improves the vibration isolation effect of the vibration isolation trench, ensures the quality of the vibration isolation trench, enables the vibration isolation trench to better play the vibration isolation role, simplifies the construction process and reduces the construction cost.

[0068] After the construction of a single vibration isolation trench is completed, move the position of the static press 2 to the construction position of the next vibration isolation trench, and repeat the above process to perform the construction operation of the next vibration isolation trench. The insertion plate 1 is inserted into the soil by static pressure to form a trench, significantly reducing the vibration generated during the construction process, especially suitable for areas with complex geological conditions, dense surrounding buildings or sensitive to vibration.

[0069] The soft-fill vibration isolation trench construction device used, its insertion plate 1 is equipped with a boot 16 device that automatically opens and closes at the bottom end, and cooperates with the silo 3 to convey flexible filling materials, which can quickly fill the vibration isolation trench, making the construction of the soft-fill vibration isolation trench no longer worry about the collapse of the trench wall and the cumbersome construction process of excavating a stepped slope, reducing the construction operation surface, reducing the project quantity, reducing the construction difficulty, especially suitable for construction in narrow spaces, and greatly shortening the construction period.

[0070] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
