Description

Technical Field

[0001] This invention belongs to the field of underwater pipe pile construction positioning technology, specifically relating to an underwater pipe pile row-type pile driving positioning device and its construction method for positioning, guiding, and facilitating construction turnover of multiple pipe piles in water. Background Technology

[0002] During the construction of underwater pipe piles, it is necessary to accurately position the pipe piles to be driven at the designed pile positions and control the lateral offset and tilt of the pipe piles, as well as the distance between adjacent pipe piles, during the pile driving process. Since the construction area is located on or in water, the pipe piles are easily affected by water flow, hoisting sway, and water operation conditions during hoisting and positioning, resulting in problems such as difficulty in pipe pile alignment, easy offset after positioning, and difficulty in controlling positioning accuracy.

[0003] For multiple pipe piles arranged in a row, if a positioning structure is set up for each pipe pile and each one is measured and calibrated, not only are there many installation procedures, but the lack of a unified geometric benchmark between the independent positioning structures can easily cause uneven spacing between adjacent pipe piles or uneven alignment of the entire row of pipe piles, which in turn affects the installation of subsequent connection structures.

[0004] When using a fixed, enclosed positioning structure, the pipe pile typically needs to be aligned from above the positioning area before being driven in. During water-based hoisting, longer pipe piles are prone to swaying, requiring repeated adjustments to their position, which is inconvenient. After pile driving is completed, separating and transferring the fixed, enclosed positioning structure from the pipe pile is also quite difficult.

[0005] In addition, some water positioning devices require specially processed components, which have a high production cycle and cost. After the device is installed, construction personnel also need to complete the positioning frame operation and status inspection on the water. If there is a lack of fixed climbing channels and protective structures, it will increase the inconvenience and safety risks of water operations.

[0006] Therefore, there is a need for a pile driving positioning device that allows pipe piles to be easily driven into position from the side, provides reliable anti-deviation constraint for the pipe piles after closure, can uniformly control the pile spacing and alignment of multiple pipe piles, can be made using common materials on the construction site, and is easy to operate on water and reuse. Summary of the Invention

[0007] Purpose of the invention: The purpose of this invention is to address the difficulties in aligning pipe piles during hoisting and positioning in water, the tendency for lateral displacement to occur during pile driving, the difficulty in uniformly controlling the pile spacing and overall alignment when positioning multiple pipe piles separately, and the inconvenience of manufacturing, installing, dismantling, and operating existing positioning structures on water. The invention provides a pipe pile row driving positioning device and its construction method for water.

[0008] Technical solution: This invention provides a row-type underwater pipe pile driving and positioning device, including a row-type main frame, multiple opening and closing positioning frames, multiple hinged shafts, and a lateral support system. The main frame is provided with multiple positioning stations at intervals along its length. Each positioning station includes a fixed positioning part set on the main frame and an openable positioning frame corresponding to the fixed positioning part. The spacing between the multiple positioning stations is set according to the design pile spacing of the pipe piles to be driven, so that the multiple positioning stations use the same main frame as a common positioning reference. The first end of the hinged positioning frame is rotatably connected to the main frame via a hinge shaft, allowing the hinged positioning frame to rotate between the open and closed positions relative to the main frame. When the hinged positioning frame is in the open position, a lateral entrance is formed on the side of the corresponding positioning position, allowing the pipe pile to be driven to enter from the side. The second end of the opening / closing positioning frame is equipped with an embedded closure, and the main frame of the row is equipped with a limiting fitting part corresponding to the embedded closure. When the opening / closing positioning frame rotates to the closed position, the embedded closure enters the limiting fitting part, and the opening / closing positioning frame and the fixed positioning part together form a closed-loop limiting zone for accommodating the pipe pile to be driven and limiting its lateral displacement. At this time, the first end of the opening / closing positioning frame is constrained by the hinge shaft, and the second end is constrained by the cooperation relationship between the embedded closure and the limiting fitting part, so that the opening / closing positioning frame forms a closed load-bearing state with both ends constrained.

[0009] Furthermore, the limiting and fitting part is formed by an I-beam member mounted on the main frame. The I-beam member includes an upper flange, a lower flange, and a web connecting the upper and lower flanges. The upper and lower flanges and the web form an opening facing the lateral limiting space of the opening and closing positioning frame. When the opening and closing positioning frame is in the closed position, the embedded closing part is located between the upper and lower flanges and faces the web. The upper and lower flanges restrict the vertical displacement of the embedded closing part, and the web restricts the displacement of the embedded closing part towards the bottom of the lateral limiting space.

[0010] Furthermore, the hinge axis is set vertically, and the opening and closing positioning frame can rotate in the horizontal plane around the hinge axis; the closed-loop limiting area formed after the opening and closing positioning frame is closed is square.

[0011] Furthermore, the lateral support system includes transverse lateral supports, vertical lateral supports, and external connection supports. The transverse lateral supports are diagonally installed within the horizontal grids of the row-type main frame, the vertical lateral supports are diagonally installed within the fixed vertical grids of the row-type main frame, and the external connection supports connect the row-type main frame with the external positioning support structure.

[0012] Furthermore, a ladder is fixedly installed on the side of the main frame, and a guardrail is installed on the outside of the ladder; multiple lifting lugs are spaced apart on the top of the main frame along its length.

[0013] Furthermore, the main frame, the retractable positioning frame, and the lateral support system are made of common steel and steel pipes such as I-beams, channel steel, and steel pipes commonly used on construction sites. Detachable connections are made with bolts or pins, and fixed nodes subjected to greater stress can be connected by welding.

[0014] The present invention also provides a method for pile driving construction using the above-mentioned underwater pipe pile row-type pile driving positioning device, comprising: The main frame is installed on the external positioning support structure, so that multiple positioning positions correspond to the design pile positions of multiple pipe piles to be driven. Rotate the opening and closing positioning frame at the corresponding positioning station around the hinge axis to the open position to form a lateral entrance on the side of the positioning station. The pipe pile to be driven is moved from the side through the lateral entrance into the positioning position; Rotate the opening and closing positioning frame to the closed position so that the embedded closed part enters the limiting fit part, and the opening and closing positioning frame and the fixed positioning part together form a closed loop limiting area; The insertion and closed limiting of multiple pipe piles to be driven are completed in sequence, and the pile driving operation is carried out under the condition that the lateral displacement of the corresponding pipe pile is restricted in the closed-loop limiting area. After the pile driving is completed, the opening and closing positioning frame is rotated to the open position, the restriction is released from the side of the driven pipe pile, and the positioning device is disassembled, hoisted and transferred to the next construction area.

[0015] Beneficial effects: The present invention uses a row-type main frame as a common positioning reference and sets up opening and closing positioning frames that can be opened and closed laterally at multiple positioning positions. This allows the pipe pile to enter from the side during the placement stage and to be subject to lateral anti-deviation constraint through the closed-loop limiting zone during the pile driving stage. This balances the convenience of pipe pile placement, the positioning accuracy of multiple piles, and the stability of the pile driving process, and has the following beneficial effects.

[0016] 1. Reduce the difficulty of alignment during pipe pile installation. The hinged positioning frame is rotatably connected to the main frame via a hinged shaft. After the positioning frame is rotated to the open position, an open side entrance is formed on the side of the positioning station, allowing the pipe piles hoisted to the side of the positioning device to enter the positioning station from the side.

[0017] Compared to the method of aligning the pipe pile from above the closed positioning area before inserting it, this structure eliminates the process of precise vertical alignment between the lower end of the pipe pile and the closed positioning port, making it easier to complete the insertion in a waterborne operation environment where the pipe pile is subject to hoisting sway.

[0018] 2. Improve the anti-displacement capability of the opening and closing positioning frame after it is closed. One end of the hinged positioning frame is connected to the main frame via a hinge shaft, and the other end is equipped with an embedded closing part. When the positioning frame is closed, the embedded closing part enters the limiting fit part on the main frame, thereby constraining both the hinged end and the closed end of the positioning frame.

[0019] Therefore, the hinged positioning frame can rotate around the hinge axis in the open state, and in the closed state, it no longer relies solely on the hinge end for single-end support, but instead forms a closed bearing state with both ends constrained. When the pipe pile exhibits a lateral deviation tendency, the deviation thrust can be borne by the hinged positioning frame and the fixed positioning part, and transmitted to the main frame through the hinge end and the closed end, reducing the risk of the positioning frame opening on its own or undergoing significant deformation under stress.

[0020] 3. Utilizing the I-beam cross-section to simultaneously achieve load-bearing and closed-loop limiting. The main frame of the row-type structure uses I-beams at the closed end of the opening and closing positioning frame. The upper flange, lower flange, and web of the I-beams form a lateral limiting space. After the embedded closing part enters this lateral limiting space, the upper and lower flanges restrict its vertical displacement, and the web restricts its displacement towards the bottom of the channel.

[0021] Therefore, the same I-beam component serves as both a load-bearing component of the main frame and a limiting fit part at the closed end, eliminating the need for a separate, complex, dedicated closing mechanism. This facilitates the use of commonly used steel profiles on-site for fabrication and maintenance.

[0022] 4. Maintain unified control over the spacing and alignment of multiple pipe piles. Multiple positioning stations are set up together on the same row of main frames according to the design pile spacing of the pipe piles to be driven. The relative positions between each closed-loop limiting zone are predetermined by the main frame.

[0023] Therefore, there is no need to build independent positioning structures for each pipe pile and establish positioning benchmarks one by one. The relative positions of multiple pipe piles can be controlled simultaneously using the same row of main frames. This helps to maintain uniform spacing between adjacent pipe piles and straight alignment of the entire row of pipe piles, and provides a positional basis for subsequent connection construction between pipe piles.

[0024] 5. Form a complete off-center load transfer path. Lateral and vertical lateral supports are respectively installed in different directional frames of the main frame and form an oblique reinforcement structure with adjacent fixed components to suppress lateral displacement, shear deformation and torsion of the main frame under the action of pipe pile offset load.

[0025] The external connection support further connects the main frame to the external positioning support structure, so that the offset thrust of the pipe pile can be transmitted from the fixed positioning part and the opening and closing positioning frame to the main frame, and then to the external positioning support structure through the lateral support system, thus avoiding the pipe pile offset load from being concentrated on a single positioning position.

[0026] 6. Provide fixed water climbing and operation channels. Ladders are fixedly installed on the sides of the main frame, and guardrails are installed on the outside of the ladders. Construction workers can reach the operating positions on the upper part of the main frame and the opening and closing frame via the ladders, without the need to temporarily erect climbing structures or climb the main frame by hand. This facilitates the opening and closing of the positioning frame, the inspection of the pins, and the inspection of the equipment status, improving the convenience and safety of operations on water.

[0027] 7. Facilitates overall hoisting, disassembly, and repeated use. The main frame, arranged in a row, has multiple lifting lugs along its length at the top, allowing for the connection of lifting equipment and the overall hoisting of the long, narrow main frame. Removable parts of the assembly are connected using bolts or pins, reducing the need for cutting and re-welding after construction.

[0028] After the pile driving is completed, the opening and closing positioning frame can be opened from the side of the pipe pile to release the enclosure relationship between the closed-loop limiting area and the pipe pile. Then, the external connecting support can be removed and the device can be hoisted as a whole, which makes it easy to transfer the device to the next construction area for reuse.

[0029] 8. Multiple structures create a synergistic positioning effect. The row-type main frame provides a unified benchmark for multiple positioning stations. The openable positioning frame realizes the switching between lateral pile entry and closed anti-deviation states. The embedded closing part and the limiting part make the positioning frame form a constrained state at both ends after closing. The lateral support system then transfers the local deviation load to the external positioning support structure.

[0030] The above structures work together to enable this device to complete the operation according to the process of "lateral opening - pipe pile placement - closed limit - row pile driving - lateral release - overall turnover", which reduces the placement and alignment process while realizing the common positioning of multiple pipe piles and preventing pile driving deviation.

Detailed Implementation

[0033] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the embodiments described.

[0034] Example 1: Underwater Pipe Pile Row Positioning Device like Figures 1 to 5 As shown, this embodiment provides a row-type underwater pipe pile driving and positioning device, including a row-type main frame 1, multiple opening and closing positioning frames 2, multiple hinged shafts 3, a lateral support system 4, and a ladder 5.

[0035] 1. Row-style main frame The main frame 1 extends along the direction of the piles to be constructed, and its overall structure is a long strip beam or truss structure. The main frame 1 is made of common steel sections and steel pipes such as I-beams, channel steel, and steel pipes commonly used on construction sites.

[0036] The main frame 1 is arranged with multiple positioning stations at intervals along its length, each positioning station corresponding to a designed pile position of a pipe pile 6 to be inserted. The center-to-center distance between adjacent positioning stations is set according to the designed pile spacing of adjacent pipe piles 6 to be inserted, so that the relative positions of each positioning station are determined by the same main frame 1.

[0037] Each positioning station includes a fixed positioning part formed on the main frame 1. The fixed positioning part is formed by the fixed frame component of the main frame 1 at the corresponding positioning station, and cooperates with the corresponding opening and closing positioning frame 2 to position the pipe pile 6 to be driven.

[0038] The top of the main frame 1 is provided with multiple lifting lugs 11 at intervals along its length. The multiple lifting lugs 11 are used to connect with the slings of the crane to carry out overall hoisting, installation and transportation of the long strip-shaped main frame 1.

[0039] 2. Opening and closing positioning frame and hinge structure Each positioning station is equipped with an opening and closing positioning frame 2. The opening and closing positioning frame 2 includes a first end and a second end, wherein the first end is rotatably connected to the row of main frames 1 through a hinge shaft 3, and the second end is a free end that can be closed and engaged with the row of main frames 1.

[0040] In this embodiment, the hinge shaft 3 is vertically arranged, and the opening and closing positioning frame 2 can rotate around the hinge shaft 3 in the horizontal plane to switch between the open and closed positions. When the opening and closing positioning frame 2 rotates around the hinge shaft 3 to the open position outside the row of main frames 1, a lateral entrance is formed between the opening and closing positioning frame 2 and the corresponding fixed positioning part. The pipe pile 6 to be driven and hoisted to the side of the device can enter the corresponding positioning position through this lateral entrance.

[0041] Once the pipe pile 6 to be driven enters the positioning position, the opening and closing positioning frame 2 rotates in the opposite direction around the hinge axis 3 to the closed position. The opening and closing positioning frame 2 and the fixed positioning part together form a closed-loop limiting area. In this embodiment, the closed-loop limiting area is square, used to circumferentially accommodate the pipe pile 6 to be driven, and to limit the displacement of the pipe pile 6 to be driven from multiple lateral directions, so that the pipe pile 6 to be driven is driven along its axial direction under the guidance of the closed-loop limiting area.

[0042] Multiple closed-loop limiting zones are set together on the same row of main frames 1. Therefore, the center distance between each closed-loop limiting zone is predetermined by the row of main frames 1, forming a common positioning reference for multiple pipe piles 6 to be driven.

[0043] 3. Embedded closing part and limiting mating part like Figure 4 , Figure 5 As shown, the second end of the opening and closing positioning frame 2 is provided with an embedded closing part 21. The row-type main frame 1 is provided with a limit fitting part at the position corresponding to the embedded closing part 21.

[0044] In this embodiment, the limiting fitting part is formed by an I-beam member on the main frame 1. This I-beam member includes an upper flange, a lower flange, and a web connecting the upper and lower flanges. The upper flange, lower flange, and web form an opening facing the opening / closing positioning frame 2, creating a lateral limiting space. When the opening / closing positioning frame 2 rotates to the closed position, the embedded closing part 21 enters the lateral limiting space of the I-beam member along with the rotation of the opening / closing positioning frame 2, and is located between the upper and lower flanges. The upper and lower flanges limit the vertical displacement of the embedded closing part 21, and the web limits the displacement of the embedded closing part 21 towards the bottom of the lateral limiting space groove.

[0045] Therefore, when the opening and closing positioning frame 2 is in the closed position, its first end is constrained by the hinge shaft 3, and its second end is constrained by the cooperation between the embedded closing part 21 and the limiting fitting part, so that the opening and closing positioning frame 2 forms a closed bearing state with both ends constrained.

[0046] While serving as the load-bearing member of the main frame 1, the lateral space between the upper and lower flanges and the web of the I-beam is also used to accommodate and constrain the embedded closure 21, thereby using the same field-standard steel to simultaneously complete the load-bearing of the frame and the positioning of the closed end of the frame.

[0047] 4. Lateral support system The lateral support system 4 includes a transverse lateral support 41, a vertical lateral support 42, and an external connection support 43.

[0048] like Figure 2 As shown, the lateral support 41 is obliquely arranged within the horizontal frame of the row-type main frame 1, and together with the longitudinal and lateral fixing members of the row-type main frame 1, it forms a triangular reinforcing unit to improve the overall stiffness of the row-type main frame 1 in the horizontal plane and suppress the lateral shear deformation and torsion of the main frame.

[0049] like Figure 3 As shown, the vertical lateral support 42 is obliquely arranged within the fixed vertical frame of the row-type main frame 1. The two ends of the vertical lateral support 42 are respectively connected to the fixed upper and lower components of the row-type main frame 1, and together with the adjacent fixed vertical components, form a triangular reinforcing unit to improve the resistance to lateral displacement and deformation of the row-type main frame 1 in the vertical side. The vertical lateral support 42 is located in the fixed structure of the main frame and does not obstruct the rotation of the opening and closing positioning frame 2 around the hinge axis 3.

[0050] One end of the external connecting support 43 is connected to the row-type main frame 1, and the other end extends outward and connects to the external positioning support structure 7. The external positioning support structure 7 can specifically be a positioning support frame set up in the construction area on the water. The positioning support frame can be set up on the construction platform on the water or carried by the floating crane 8, and will be kept fixed in place before the pipe pile positioning and pile driving operations are carried out.

[0051] 5. Ladders and protective structures like Figure 1 , Figure 3 As shown, a ladder 5 is fixedly installed on the side of the main frame 1. The ladder 5 extends along the height of the main frame 1, with its lower part close to the construction platform on the water or a position accessible to construction personnel, and its upper part extending to the operating area of ​​the opening and closing positioning frame 2 and the upper part of the main frame 1. The ladder 5 provides a fixed climbing passage for construction personnel, allowing them to reach the corresponding operating positions and open, close, and check the status of the opening and closing positioning frame 2. A guardrail 51 is installed on the outside of the ladder 5 to provide lateral protection for construction personnel during the climbing process.

[0052] 6. Materials and Connection Methods The main frame 1, the hinged positioning frame 2, the lateral support system 4, and the ladder 5 are all constructed using materials commonly available on the construction site, such as I-beams, channel steel, and steel pipes. The hinge shaft 3 uses a pin-type structure to form a rotating connection between the hinged positioning frame 2 and the main frame 1. Components that need to be disassembled and rotated are connected using bolts or pins, while fixed nodes subjected to high stress and not requiring frequent disassembly can be connected by welding.

[0053] The above connection method can reduce repeated cutting and welding on site while ensuring the overall stress of the device, and facilitates the installation, disassembly and transportation of the device.

[0054] 7. The force transmission principle of the device During pile driving, when the pipe pile 6 to be driven exhibits a lateral deviation tendency and applies a thrust to the corresponding limiting part of the closed-loop limiting zone, this thrust is borne by the fixed positioning part and the opening and closing positioning frame 2. The load acting on the opening and closing positioning frame 2 is transmitted to the row-type main frame 1 through the hinge shaft 3 at its first end and the embedded closing part 21 and limiting fitting part at its second end. The row-type main frame 1 distributes the local load to a larger area of ​​the main frame through its longitudinal members, transverse members, transverse lateral supports 41 and vertical lateral supports 42, and then transmits it to the external positioning support structure 7 through the external connecting support 43.

[0055] The main force transmission path of this device is as follows: the offset thrust of the pipe pile 6 to be driven is transmitted through the fixed positioning part and the opening and closing positioning frame 2 to the hinge shaft 3 and the embedded closing part 21, then to the row-type main frame 1, and then to the external positioning support structure 7 through the lateral support system 4.

[0056] Example 2: Pile Driving Construction Method This embodiment provides a method for pile driving construction using the underwater pipe pile row-type pile driving positioning device described in Embodiment 1, specifically including the following steps.

[0057] Step 1: Material Selection and Production Based on the pile diameter, design pile spacing, and number of pipe piles to be driven (6), the length of the main frame 1, the number of positioning positions, and the spacing between adjacent positioning positions are determined. Using readily available materials on the construction site, such as I-beams, channel steel, steel pipes, pins, and bolts, the main frame 1, the hinged positioning frame 2, the lateral support system 4, and the ladder 5 are constructed. Multiple lifting lugs 11 are installed at the top of the main frame 1, and guardrails 51 are installed on the outside of the ladder 5. I-beams are used at the closed end of the hinged positioning frame 2 corresponding to the position of the main frame 1, utilizing the lateral space between the flanges and webs of the I-beams to form a limiting fit.

[0058] Step 2: Hoisting and positioning the device Using a crane with multiple lifting lugs 11, the entire main frame 1 is hoisted to the construction area on the water and installed on the external positioning support structure 7. The position of the main frame 1 is adjusted so that each positioning position corresponds to the designed pile position of the corresponding pipe pile 6 to be driven, and the main frame 1 is fixedly connected to the external positioning support structure 7 through the external connecting support 43. When the external positioning support structure 7 is carried by the floating crane 8, the external positioning support structure 7 and the main frame 1 are kept fixed in place before the pipe pile insertion and pile driving operations.

[0059] Step 3: Open the hinged positioning frame For the positioning position corresponding to the pipe pile to be installed, the opening and closing positioning frame 2 at the positioning position is rotated around the hinge axis 3 to the outside of the row of main frames 1, so that the opening and closing positioning frame 2 is in the open position. After the opening and closing positioning frame 2 is opened, a lateral entrance is formed on the side of the corresponding positioning position.

[0060] Step 4: Lateral placement of the pipe pile The pipe pile 6 to be driven is hoisted to the outside of the side entrance using a crane, and then enters the corresponding positioning position from the side through the side entrance. After the pipe pile enters from the side, its position is adjusted so that it is located within the area that can be jointly enclosed by the corresponding fixed positioning part and the opening and closing positioning frame 2.

[0061] Step 5: Close the limit switch The opening / closing positioning frame 2 is rotated around the hinge axis 3 to the closed position, causing the embedded closing part 21 at the second end of the opening / closing positioning frame 2 to enter the limiting fit part formed by the I-beam component. The opening / closing positioning frame 2 and the fixed positioning part together form a square closed-loop limiting area, within which the pipe pile 6 to be driven is located. The first end of the opening / closing positioning frame 2 is constrained by the hinge axis 3, and the second end is constrained by the embedded closing part 21 and the limiting fit part, thus forming a closed load-bearing state with both ends constrained.

[0062] Step Six: Repeat the installation of the row of pipe piles. Following the arrangement of multiple positioning stations on the main frame 1, the remaining piles to be driven 6 are subjected to the same repeated operations of opening and closing the positioning frame 2, laterally moving the piles in, and closing the positioning frame until all the piles to be driven 6 have entered their respective closed-loop limiting zones. Since multiple positioning stations are set on the same main frame 1, the relative distance between each pile to be driven 6 is controlled by the preset spacing between each positioning station.

[0063] Step 7: Carry out pile driving operation With each of the pipe piles 6 to be driven in its corresponding closed-loop limiting zone, the pile driving operation is carried out sequentially. During the pile driving process, the closed-loop limiting zone restricts the lateral displacement of the pipe piles; the offset thrust generated by the pipe piles is transmitted through the fixed positioning part, the opening and closing positioning frame 2, the hinge shaft 3, the embedded closing part 21, and the row-type main frame 1, and further transmitted to the external positioning support structure 7 through the lateral support system 4. Multiple positioning positions work together to maintain the relative position between each pipe pile, which is beneficial for controlling the pile spacing and arrangement alignment of the entire row of pipe piles.

[0064] Step 8: Opening, Disassembling, and Handling After the pile driving operation in the corresponding construction area is completed, each openable positioning frame 2 is rotated around the corresponding hinge axis 3 to the open position, so that the openable positioning frame 2 is released from the side of the driven pipe pile. Subsequently, the connection between the external connecting support 43 and the external positioning support structure 7 is released, and the main frame 1 and its auxiliary components are lifted as a whole by a crane through the lifting lug 11 and transferred to the next construction area. After the positioning device is readjusted and fixed in the next construction area, the above-mentioned pipe pile placement, closing limit, pile driving and dismantling turnover process can be repeated.

[0065] The I-beams, channel steel, steel pipes, pins, and bolts used in the above embodiments are all common field materials recorded in the original technical disclosure. The specific length and cross-sectional specifications of each component are determined according to the pile diameter, design pile spacing, and number of positioning stations of the pipe piles to be driven 6. The original technical disclosure did not record specific values, so this specification does not limit the specific size range separately.

[0066] As described above, although the invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the invention itself. Various changes in form and detail may be made without departing from the spirit and scope of the invention as defined in the appended claims.
