[0002] This section provides only background information relevant to this disclosure and is not necessarily prior art.

[0003] In the construction of underground buildings such as basements, steel pipe columns are commonly used as supporting structures to increase the stability and load-bearing capacity of the basement. During construction, the steel pipe columns are fixed in the foundation and connected to other structural elements through connectors to build a stable basement frame.

[0004] When installing steel pipe columns using the cut-and-cover method, the steel pipe columns need to be inserted into the drilled holes, and the holes need to be filled with sand. The existing method of sand filling is to use a loader or excavator to backfill directly. During the sand filling process, the height difference of the fill material on both sides of the column is often different, which generates lateral pressure, which in turn squeezes the steel pipe column, causing the steel pipe column to tilt and thus affecting the construction quality.

Detailed Implementation

[0018] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0019] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0020] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0021] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0022] To address the problem of uneven fill material heights on both sides of existing steel pipe columns during sand filling, which generates lateral pressure and subsequently squeezes the steel pipe columns, causing them to tilt and affecting construction quality, this embodiment proposes a sand filling balancing device for underground chamber steel pipe columns. The details are attached below. Figure 1-6 The structure of the sand-filling balancing device for the underground chamber steel pipe column in this embodiment will be described.

[0023] Figure 1 A schematic diagram of the structure of the sand-filling balancing device for the steel pipe column of an underground chamber according to an embodiment of the present invention is shown.

[0024] Combined with appendix Figure 1 As shown in the figure, according to an embodiment of the present invention, a sand-filling balancing device for underground tunnel steel pipe columns is proposed, which includes a receiving unit 100, a conveying unit 200, and a vertical adjustment unit 300. When carrying out sand-filling operations for steel pipe columns, the verticality of the steel pipe columns is adjusted and the steel pipe columns are fixed by the vertical adjustment unit 300. Then, the receiving unit 100 is used to receive the sand for filling. The sand received by the receiving unit 100 can fall to the conveying unit 200 of this embodiment to transport the sand to the filling position, thereby improving the efficiency of the sand-filling operation for steel pipe columns.

[0025] In order to avoid the problem of uneven filling height on both sides of the column, prevent the generation of lateral pressure, improve the stability of the steel pipe column after sand filling, and ensure the construction quality of underground engineering, this embodiment makes improvements to the structure of the material receiving unit 100, the conveying unit 200, and the vertical adjustment unit 300.

[0026] Figure 2 The schematic diagram shows the structure of the receiving unit 100 and the conveying unit 200 of the underground chamber steel pipe column external sand filling balancing device according to an embodiment of the present invention.

[0027] Combined with appendix Figure 2 As shown, the receiving unit 100 of this embodiment includes a support frame 110 and a receiving hopper 120 mounted on the support frame 110. The support frame 110 of this embodiment is the mounting base of the receiving hopper 120. The support frame 110 can be made of metal. The top of the support frame 110 is provided with a mounting frame, and the bottom of the support frame 110 is provided with a support leg 310. The receiving hopper 120 of this embodiment is mounted on the mounting frame.

[0028] To ensure that the sand is separated into two parts during discharge, thereby uniformly filling both sides of the steel pipe column, this embodiment designs the receiving hopper 120 as including a hopper body 121, a first partition 122, and a second partition 123. In this embodiment, the top of the hopper body 121 is provided with a feed inlet, and the bottom of the hopper body 121 is provided with a discharge outlet.

[0029] In this embodiment, the first partition 122 and the second partition 123 are installed inside the hopper body 121. The first partition 122 and the second partition 123 form an inverted V-shaped structure. Specifically, the upper end of the first partition 122 and the upper end of the second partition 123 are connected, and the lower end of the first partition 122 and the lower end of the second partition 123 have a preset interval. The first partition 122 and the second partition 123 divide the hopper body 121 into a first feeding area 1211 and a second feeding area 1212. The two sides of the inverted V-shaped structure facilitate the sand material to enter the conveying unit 200 below from the first feeding area 1211 and from the second feeding area 1212.

[0030] Accordingly, to accommodate the aforementioned receiving unit 100, this embodiment designs the conveying unit 200 as including a first conveying device 210 and a second conveying device 220. In this embodiment, the first conveying device 210 is located directly below the first unloading area 1211, and is used to receive the incoming material from the first unloading area 1211 and convey it to one side of the sand-filling area of ​​the steel pipe column. In this embodiment, the second conveying device 220 is located directly below the second unloading area 1212, and is used to receive the incoming material from the second unloading area 1212 and convey it to the other side of the sand-filling area of ​​the steel pipe column. This ensures that the sand-filling height on both sides of the steel pipe column remains essentially consistent, avoiding lateral pressure.

[0031] Figure 3 A schematic diagram of the conveying unit structure of the sand-filling balancing device for the steel pipe column of an underground chamber according to an embodiment of the present invention is shown.

[0032] Combined with appendix Figure 3As shown, the first conveying device 210 of this embodiment includes a first frame 211, a first belt conveyor mechanism 212, and a first traveling wheel 213. The second conveying device 220 of this embodiment includes a second frame 221, a second belt conveyor mechanism 222, and a second traveling wheel 223.

[0033] In this embodiment, the first belt conveyor mechanism 212 is mounted on the first frame 211 and located below the first unloading area 1211. In this embodiment, the first traveling wheel 213 is mounted on the first frame 211 to facilitate the movement of the first belt conveyor mechanism 212.

[0034] Similarly, in this embodiment, the second belt conveyor mechanism 222 is mounted on the second frame 221 and located below the second unloading area 1212. In this embodiment, the second traveling wheel 223 is mounted on the second frame 221 to facilitate the movement of the second belt conveyor mechanism 222.

[0035] In some examples, the first belt conveyor mechanism 212 of this embodiment includes a first belt 2121, a first drive roller 2122, a first tension roller 2123, a plurality of first support rollers 2124 and a plurality of second support rollers 2125.

[0036] In this embodiment, the first drive roller 2122 is installed at one end of the first frame 211, the first tension roller 2123 is installed at the other end of the first frame 211, the plurality of first support rollers 2124 are arranged along the length direction of the first frame 211 on one side of the width direction of the first frame 211, and the plurality of second support rollers 2125 are arranged along the length direction of the second frame 221 on the other side of the width direction of the first frame 211, and the plurality of first support rollers 2124 and the plurality of second support rollers 2125 are arranged opposite each other and have a preset interval.

[0037] Furthermore, from one side to the other in the width direction of the first frame 211, the height of the first support roller 2124 gradually decreases, and the height of the second support roller 2125 gradually increases. The lowest end of the first support roller 2124 and the lowest end of the second support roller 2125 are level, and the highest end of the first support roller 2124 and the highest end of the second support roller 2125 are level. One end of the belt is connected to the first drive roller 2122, and the other end is connected to the first tension roller 2123. The first belt 2121 is at least partially located on the plurality of first support rollers 2124 and the plurality of second support rollers 2125.

[0038] The first support roller 2124 and the second support roller 2125 form an approximately V-shaped support structure, which allows the middle of the first belt 2121 to form a downward indentation, thus preventing sand from overflowing onto the first belt 2121.

[0039] The second belt conveyor mechanism 222 in this embodiment has the same structure as the first belt conveyor mechanism 212, and will not be described further in this embodiment.

[0040] Figure 4 A schematic diagram of the vertical adjustment unit 300 of the sand-filling balancing device for underground tunnel steel pipe columns according to an embodiment of the present invention is shown.

[0041] Combined with appendix Figure 4 As shown in the figure, the vertical adjustment unit 300 of this embodiment is used to install and fix the steel pipe column and to adjust the verticality of the steel pipe column.

[0042] In this embodiment, the base 320 is mounted on multiple support legs 310. The first support leg 310 allows the base 320 to have a certain height, facilitating the insertion of the aforementioned conveying unit 200 for sand filling of the steel pipe column. The base 320 also has through holes (not shown in the figure) for inserting the steel pipe column.

[0043] In this embodiment, the first pressing platform device 330 is installed at one end of the base 320, and the second pressing platform device 340 is installed at the other end of the base 320. The support leg 310 is used to support the entire base 320. The first clamping device 350 and the second clamping device 360 ​​are located between the first pressing platform device 330 and the second pressing platform device 340. The cross-sections of the first clamping device 350 and the second clamping device 360 ​​are both arc-shaped, and the first clamping device 350 and the second clamping device 360 ​​form a clamping space for clamping the steel pipe column.

[0044] In this embodiment, the first clamping device 350 and the second clamping device 360 ​​have the same structure and are symmetrically arranged with respect to the aforementioned first clamping cylinder 390 and second clamping cylinder 3100. One end of the first clamping device 350 is connected to one end of the second clamping device 360 ​​via the first clamping cylinder 390, and the other end of the first clamping device 350 is connected to the other end of the second clamping device 360 ​​via the second clamping cylinder 3100. The first clamping cylinder 390 is used to adjust the distance between one end of the first clamping device 350 and one end of the second clamping device 360, and the second clamping cylinder 3100 is used to adjust the distance between the other end of the first clamping device 350 and the other end of the second clamping device 360.

[0045] One of the two first positioning cylinders 370 is installed on the first pressing platform device 330, and the other first positioning cylinder 370 is installed on the second pressing platform device 340. Both first positioning cylinders 370 are connected to the first clamping device 350 and are used to move the first clamping device 350 closer to or away from the second clamping device 360. One of the two second positioning cylinders 380 is installed on the first pressing platform device 330, and the other second positioning cylinder 380 is installed on the second pressing platform device 340. Both second positioning cylinders 380 are connected to the second clamping device 360 ​​and are used to move the second clamping device 360 ​​closer to or away from the first clamping device 350.

[0046] Furthermore, the sag adjustment unit 300 of this embodiment also includes at least one first initial adjustment cylinder 3110 and at least one second initial adjustment cylinder 3120; the first initial adjustment cylinder 3110 is inserted into the first clamping device 350, the length direction of the piston rod of the first initial adjustment cylinder 3110 is arranged radially along the first clamping device 350, and the piston rod of the first initial adjustment cylinder 3110 can extend or retract within the clamping space. The second initial adjustment cylinder 3120 of this embodiment is inserted into the second clamping device 360, the length direction of the piston rod of the second initial adjustment cylinder 3120 is arranged radially along the second clamping device 360, and the piston rod of the second initial adjustment cylinder 3120 can extend or retract within the clamping space.

[0047] In some examples, the number of the first initial adjustment cylinder 3110 and the second initial adjustment cylinder 3120 in this embodiment are both multiple, so as to better adjust the steel pipe column.

[0048] Before filling the steel pipe column with sand, the steel pipe column is first hoisted into the clamping space formed by the first clamping device 350 and the second clamping device 360 ​​by a crane or other structure. Then, the verticality and position of the steel pipe column are initially adjusted by the initial adjustment cylinder to keep the steel pipe column vertical.

[0049] Then, the first positioning cylinder 370 and the second positioning cylinder 380 of this embodiment are used to adjust the first clamping device 350 and the second clamping device 360 ​​to ensure that the steel pipe column is located in the center of the clamping space and maintains its verticality. Finally, the first clamping cylinder 390 and the second clamping cylinder 3100 are used to clamp the steel pipe column with the first clamping device 350 and the second clamping device 360 ​​to ensure the verticality and stability of the steel pipe column during the sand filling process.

[0050] Since the first clamping device 350 and the second clamping device 360 ​​in this embodiment are heavy, which is not conducive to transportation and assembly, the first clamping device 350 and the second clamping device 360 ​​in this embodiment are designed as separate structures that can be disassembled and assembled.

[0051] Figure 5The diagram schematically illustrates the structure of the first clamping device 350 and the second clamping device 360 ​​of the underground chamber steel pipe column external sand filling balancing device according to an embodiment of the present invention. Figure 6 for Figure 5 Enlarged view of part A, Figure 7 The diagram schematically illustrates the connection between the first upper arc clamp 351 and the first lower arc clamp 352 of the sand-filling balancing device for the steel pipe column of an underground chamber according to an embodiment of the present invention.

[0052] Combined with appendix Figure 5 Appendix Figure 6 and appendix Figure 7 As shown in the figure, in this embodiment, the first clamping device 350 is designed to include a first upper arc clamp 351, a first lower arc clamp 352, a first locking pin 353, a first wedge block 354, and a first connecting bolt 355.

[0055] The first locking pin 353 is provided with a second insertion hole (not shown in the figure). The first locking pin 353 is inserted into the first pin hole and the first upper sleeve 357. The first wedge block 354 is inserted into the first insertion hole 3571 and the second insertion hole. One end of the first wedge block 354 is connected to the first wedge block fixing plate 358 by the first connecting bolt 355.

[0056] In this way, the first upper arc clamp 351 and the first lower arc clamp 352 can be assembled through the first locking pin 353 and the first wedge block 354.

[0057] Similarly, the second clamping device 360 ​​in this embodiment includes a second upper arc-shaped clamp 361, a second lower arc-shaped clamp 362, a second locking pin, a second wedge block, and a second connecting bolt. The second locking pin, second wedge block, and second connecting bolt are not shown in the figure. The second upper arc-shaped clamp 361 in this embodiment is provided with a third connecting frame, which includes a second upper sleeve and a second wedge block fixing plate. The second upper sleeve has a third insertion hole. Correspondingly, the second lower arc-shaped clamp 362 in this embodiment is provided with a fourth mounting frame, which has a second pin hole. The second locking pin has a fourth insertion hole and is inserted into the second pin hole and the second upper sleeve. The second wedge block is inserted into the third and fourth insertion holes, and one end of the second wedge block is connected to the second wedge block fixing plate via a second connecting bolt.

[0058] Since the second upper arc clamp 361 in this embodiment has the same structure and connection principle as the first upper arc clamp 351, the second lower arc clamp 362 and the first lower arc clamp 352, the second locking pin and the first locking pin 353, the second wedge block and the first wedge block 354, and the second connecting bolt and the first connecting bolt 355, this embodiment does not provide accompanying drawings for the second locking pin, the second wedge block, the second connecting bolt, etc. Those skilled in the art can refer to the corresponding structure of the first clamping device 350 for understanding.

[0059] In some examples, the first upper arc clamp 351 of this embodiment includes a first upper arc segment 3511, a second upper arc segment 3512, and a first upper connecting shaft 3513. At one end of the first upper arc segment 3511, a plurality of first upper shaft seats 3514 are arranged at intervals from top to bottom, and at one end of the second upper arc segment 3512, a plurality of second upper shaft seats 3515 are arranged at intervals from top to bottom. The plurality of second upper shaft seats 3515 and the plurality of first upper shaft seats 3514 are arranged alternately in the vertical direction. The first upper connecting shaft 3513 is inserted into the plurality of first upper shaft seats 3514 and the plurality of second upper shaft seats 3515.

[0060] Similarly, the first lower arc clamp 352 in this embodiment includes a first lower arc segment, a second lower arc segment, and a first lower connecting shaft (not shown in the figure). One end of the first lower arc segment is provided with a plurality of first lower shaft seats arranged at intervals from bottom to top; one end of the second lower arc segment is provided with a plurality of second lower shaft seats arranged at intervals from bottom to top. The plurality of second lower shaft seats and the plurality of first lower shaft seats are staggered in the vertical direction, and the first lower connecting shaft is inserted into the plurality of first lower shaft seats and the plurality of second lower shaft seats.

[0061] The second upper arc clamp 361 in this embodiment has the same structure as the first upper arc clamp 351, and the second lower arc clamp 362 in this embodiment has the same structure as the first lower arc clamp 352. Therefore, this embodiment does not provide a detailed description of the structure of the second upper arc clamp 361 and the second lower arc clamp 362.

[0062] The first upper arc clamp 351 is designed to include a first upper arc segment 3511 and a second upper arc segment 3512, and the first lower arc clamp 352 is designed to include a first lower arc segment and a second lower arc segment. The first upper arc clamp 351 and the first lower arc clamp 352 can be finely adjusted by the first positioning cylinder 370, the second positioning cylinder 380, the first clamping cylinder 390 and the second clamping cylinder 3100 to ensure that the first clamping device 350 and the second clamping device 360 ​​of this embodiment can clamp and fix the steel pipe column and maintain the verticality of the steel pipe column.

[0063] In order to facilitate the fine-tuning of rotation between the first upper arc segment 3511 and the second upper arc segment 3512 in this embodiment, so that the first clamping device 350 can better clamp the steel pipe column, this embodiment provides a rotation guide structure on the first clamping device 350.

[0064] The rotation guide structure includes a first rotation guide plate 35111 connected to the top of one end of the first upper arc segment 3511, and a second rotation guide plate 35121 provided at the top of one end of the second upper arc segment 3512.

[0065] Furthermore, in this embodiment, the first rotating guide plate 35111 is provided with a receiving hole 35112 for accommodating the first upper connecting shaft 3513. The radial dimension of the receiving hole 35112 is larger than the radial dimension of the first upper connecting shaft 3513. The first rotating guide plate 35111 is provided with a concave first arc-shaped guide surface 35113.

[0066] Accordingly, in this embodiment, a second rotation guide plate 35121 is provided at the top of one end of the second upper arc segment 3512, and the second rotation guide plate 35121 is provided with a convex second arc-shaped guide surface 35122. The first arc-shaped guide surface 35113 and the second arc-shaped guide surface 35122 abut against each other, and the curvature of the first arc-shaped guide surface 35113 is less than the curvature of the second arc-shaped guide surface 35122.

[0067] When the first positioning cylinder 370, the first clamping cylinder 390, and the second clamping cylinder 3100 in this embodiment are activated, they can drive the first upper arc segment 3511 and the second upper arc segment 3512 to rotate relative to each other, so that the inner wall of the first clamping device 350 is pressed against the steel pipe column, ensuring the fixing and vertical adjustment effect of the steel pipe column.

[0068] Similarly, the structure of the second clamping device 360 ​​in this embodiment has the aforementioned rotational guiding structure, which will not be described in detail in this embodiment.

[0069] To facilitate the extension and retraction adjustment of the first positioning cylinder 370 and the second positioning cylinder 380, this embodiment provides two first hinge seats 331 in the first pressing device 330, two second hinge seats 341 in the second pressing device 340, two third hinge seats 3510 in the first clamping device 350, and two fourth hinge seats 363 in the second clamping device 360.

[0070] One of the two first positioning cylinders 370 is hinged at one end to one of the first hinge seats 331 and at the other end to one of the third hinge seats 3510; the other of the two first positioning cylinders 370 is hinged at one end to one of the second hinge seats 341 and at the other end to another third hinge seat 3510.

[0071] One end of one of the two second positioning cylinders 380 is hinged to another first hinge seat 331, and the other end is hinged to one of the fourth hinge seats 363; one end of the other of the two first positioning cylinders 370 is hinged to one of the second hinge seats 341, and the other end is hinged to another fourth hinge seat 363.

[0072] With this configuration, the first positioning cylinder 370 can drive the first upper arc segment 3511 and the second upper arc segment 3512 of this embodiment to adjust at multiple angles, which helps the first clamping device 350 of this embodiment to fit more closely to the steel pipe column. Similarly, the second positioning cylinder 380 helps the second clamping device 360 ​​of this embodiment to fit more closely to the steel pipe column, improving the more stable fixing effect and the vertical adjustment effect.

[0073] Combined again with the appendix Figure 1 As shown, the vertical adjustment unit 300 in this embodiment also includes a housing assembly 3130, which is mounted on the base 320 and surrounds the first pressure table device 330, the second pressure table device 340, the first clamping device 350, and the second clamping device 360.

[0074] In some examples, the vertical adjustment unit 300 of this embodiment also includes a ladder 3140 and a fence 3150. The ladder 3140 is mounted on the side wall of the housing assembly 3130, and the fence 3150 is mounted on the top of the housing assembly 3130. The fence 3150 is provided with an access port opposite to the ladder 3140.

[0075] The housing assembly 3130 of this embodiment can protect the sag adjustment unit 300, and the ladder 3140 and the access port facilitate on-site construction personnel to inspect and maintain the sag adjustment unit 300.

[0076] Furthermore, to facilitate height adjustment of the base 320, the support leg 310 is designed as a height-adjustable structure in this embodiment. Specifically, the support leg 310 is designed to include a leg body 311 and a leg cylinder 312. Correspondingly, this embodiment has a leg fixing frame on the side of the base 320, and the leg cylinder 312 is connected to the leg fixing frame via a flange. The upper end of the leg body 311 is connected to the lower end of the leg cylinder 312. The leg cylinder 312 can drive the base 320 of this embodiment to rise and fall.

[0077] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
