Description

Technical Field

[0001] This application relates to the technical field of monolithic track bed construction for inspection pits, and in particular to the construction method of monolithic track bed construction using the column skipping method for column-type inspection pits. Background Technology

[0002] Domestic subway lines include multiple tracks in various depot areas, and each track will generally reserve a column inspection pit for the entire track bed for at least one train.

[0003] Each column-type inspection pit's integral track bed is laid with tracks, and multiple concrete columns are also set up to support the tracks. However, the construction space for the integral track bed of the inspection pit is small. In existing technology, multiple concrete columns are generally constructed first, and then the tracks are installed. Furthermore, the construction of the subsequent tracks is carried out only after the completion of the previous column-type inspection pit's integral track bed, which makes the whole process take a long time and slows down the construction progress. At the same time, the tools and materials used in the construction process need to be transported to the next construction site after the completion of the previous construction process. This large-scale transportation consumes a lot of time and manpower, reducing construction efficiency and labor input efficiency. Summary of the Invention

[0004] To improve construction efficiency and labor input efficiency, this application provides a construction method for the integral track bed skipping column method of column inspection pit.

[0005] The column-type inspection pit integral track bed skipping column method construction method provided in this application adopts the following technical solution:

[0006] The construction method of the column-type inspection pit integral track bed skipping column method includes the following construction steps:

[0007] Step 1: Install support adjustment mechanism: Install multiple sets of support adjustment mechanisms at intervals along the length of the track on the same track surface, and then install the track onto the multiple sets of support adjustment mechanisms for support. Adjacent tracks are fixedly connected together by fasteners; each set of support adjustment mechanisms has multiple sets at intervals along the length of the track, and at least one support adjustment mechanism corresponds to at least one column body to be poured.

[0008] Step 2: Coarse and fine adjustment: The support adjustment mechanism is used to make coarse and fine adjustments to the position of the track;

[0009] Step 3: Segmented construction: The construction is carried out in segments, with each column body corresponding to a set of support and adjustment mechanisms as the unit; reinforcement binding and formwork installation are carried out at the pouring points, and finally the pouring is carried out;

[0010] Step 4: Disassembly and assembly: After the concrete strength of the column body reaches the standard, a set of support adjustment mechanisms is disassembled and transported to the subsequent track for installation and use;

[0011] Step 5: The previous stock continues to complete steps 3 and 4; at the same time, the subsequent stock completes steps 1-4;

[0012] Step 6: Complete the construction of the remaining column bodies until the construction of the track column bodies is completed.

[0013] By adopting the above technical solution, multiple sets of support and adjustment mechanisms are first fixedly installed along the length of the track on the same track. Then, the track is placed on top of the support and adjustment mechanisms for support. Adjacent tracks are fixed with fasteners. The support and adjustment mechanisms are then coarsely and finely adjusted to ensure the correct track position. Next, the pouring point located at the first set of support and adjustment mechanisms is reinforced with steel bars and the formwork is installed. Then, the pouring construction is carried out. When the concrete strength of the column body reaches the standard, multiple support and adjustment mechanisms are disassembled and transported to the subsequent track for installation and use. The transported track continues to complete the column body construction at the next set of support and adjustment mechanisms. After the construction is completed, the disassembly and transport of support and adjustment mechanisms continue. At the same time, the installation and construction of the subsequent track are carried out in the same way as the previous track. Finally, the construction of the remaining column body is completed until all tracks are completed. Therefore, the support and adjustment mechanisms can be transported and used nearby during the construction of adjacent tracks, and the transport is also carried out in sections. The construction of the previous track is carried out at the same time as the transport, which reduces the waiting time during the construction process, and also reduces the number of material turnovers and the time spent, thus improving the construction efficiency and labor input efficiency.

[0014] Optionally, the column body to be poured is divided into multiple column groups at intervals along the length of the track. Each column group includes at least two column bodies. When constructing in sections in step 3, only one column body in the column group is constructed. When constructing in step 6, the column body completed in step 3 is used as support, and then the construction of the remaining column bodies is completed.

[0015] By adopting the above technical solution, all the columns to be poured are divided into multiple column groups, each column group including at least two column bodies. Only one column body is constructed in a column group at a support and adjustment mechanism. After the column body reaches the strength standard, the support and adjustment mechanism is disassembled and transported. Finally, the constructed column body is used to support the track. Then, the remaining column bodies in the multiple column groups are constructed. This reduces the number of support and adjustment mechanisms required for the entire track, reduces the time spent on turnover, and also reduces the time spent waiting for support and adjustment mechanisms in subsequent tracks, thereby greatly improving construction efficiency and labor input efficiency.

[0016] Optionally, the support adjustment mechanism includes:

[0017] Track lifting frame, which is supported on the track surface;

[0018] A limiting component, which is mounted on the track lifting frame and is used to support and limit the movement of the track;

[0019] An adjustment component is mounted on the track jack and is used to adjust the track position.

[0020] By adopting the above technical solution, the track lifting frame is installed on the track, the track is transferred and placed on the upper surface of the track lifting frame for support, the limiting component initially limits the position of the track, and the adjusting component is activated to adjust the position of the track so that the track is in a suitable position, thereby achieving support and adjustment of the track.

[0021] Optionally, the limiting component includes:

[0022] Two fixed posts are provided on the track-raising frame.

[0023] A limiting frame, which is vertically slidably mounted on two fixed columns and located above the track lifting frame, and has an upwardly protruding limiting part;

[0024] Two limiting tubes are horizontally spaced on the limiting frame and cooperate with the two ends of the limiting part to form a limiting space for placing and limiting the two tracks; the track lifting frame is equipped with a lifting component that drives the limiting frame to move up and down.

[0025] By adopting the above technical solution, the two tracks are placed on the limiting frame and within the limiting space, thereby achieving initial positioning of the two tracks. When it is necessary to move the track lifting frame, the lifting component is activated, driving the limiting frame to move. The movement of the limiting frame causes the limiting tube and the adjusting component to move together, while the tracks are supported by the constructed column body and remain in place. This causes the limiting space and the adjusting component to move downwards simultaneously, thus disengaging the tracks from the limiting space and the adjusting component. Then, the track lifting frame can be moved to the subsequent track for installation. Next, the lifting component is activated, driving the limiting frame, limiting tube, and adjusting component to move upwards simultaneously, allowing for the installation and adjustment of the subsequent tracks. This further improves the convenience of using the support and adjustment mechanism, and increases construction efficiency and labor input efficiency.

[0026] Optionally, the adjustment component includes:

[0027] An adjusting cylinder, which is detachably mounted on a limiting frame;

[0028] Two adjusting screws are rotatably mounted on the adjusting cylinder and extend to both sides of the track.

[0029] Two push blocks are slidably disposed on both ends of the adjusting cylinder and threadedly connected to two adjusting screws respectively and correspondingly disposed on two rails. Each of the two push blocks is provided with two push plates located on both sides of the rails and used to push the rails to move.

[0030] By adopting the above technical solution, rotating the adjusting screw drives the push block and two push plates to move simultaneously. One of the push plates moves and pushes the track to one side, while rotating the adjusting screw in the opposite direction can make the other push plate push the track to the other side. Therefore, rotating the two adjusting screws can adjust the position of the two tracks, thereby improving the convenience of adjustment and construction efficiency.

[0031] Optionally, two adjacent track-raising frames are connected together by a connecting assembly, the connecting assembly comprising:

[0032] Two connecting blocks are respectively inserted and installed on two track-raising frames;

[0033] Two connecting screws are provided on two connecting blocks;

[0034] A connecting rod, the two ends of which are threaded to two connecting screws and pressed against two connecting blocks for positioning.

[0035] By adopting the above technical solution, two connecting blocks are respectively inserted and installed on two track-raising frames, thereby aligning the two adjacent track-raising frames, improving the convenience and accuracy of adjusting the track position, and increasing construction efficiency. At the same time, when the position and angle of the two adjacent track-raising frames change, the two connecting blocks are rotated to separate from the connecting rod, and then a suitable connecting rod is replaced, thereby further improving the convenience in the actual construction process and thus further improving construction efficiency.

[0036] Optionally, the track lifting frame is provided with multiple movable components for easy movement, the movable components including:

[0037] A support rod, which is vertically slidably mounted on the bottom of the track-raising frame;

[0038] The support wheel is rotatably mounted on the bottom end of the support rod; the lifting assembly is connected to the support rod and is used to drive the support rod and the limiting frame to move up and down simultaneously, so that when the support wheel is supported on the ground, the track lifting frame is disengaged from the ground and the track is disengaged from the limiting space and the four push plates.

[0039] By adopting the above technical solution, when transfer is required, the lifting assembly is activated, driving the limit frame and support wheels to move downwards simultaneously. This causes the support wheels to roll on the track while the track lifting frame moves away from the track surface. At the same time, the track disengages from the limit space and the adjustment assembly. Then, the track lifting frame is pushed, and the rotation of the support wheels enables the transfer of the track lifting frame, limit assembly, and adjustment assembly. After the track is in place, the lifting assembly is activated, driving the support rod and support wheels to move upwards, placing the track lifting frame on the track. Simultaneously, the lifting assembly also drives the limit frame, limit tube, and adjustment assembly to move upwards, allowing the track to be installed. The two tracks are then placed within the two limit spaces, and the adjustment assembly is activated to adjust the tracks, thereby providing support for the tracks. This improves the convenience and efficiency of construction.

[0040] Optionally, the lifting assembly includes:

[0041] A rack, which is slidably mounted on the track-raising frame and connected to a limiting frame and a support rod;

[0042] A gear, which is rotatably mounted on the track-raising frame and meshes with a rack;

[0043] A movable block, which is horizontally slidably mounted on the track-raising frame;

[0044] The limiting block is disposed on the lower surface of the limiting frame and both the limiting block and the moving block are provided with lifting surfaces that fit together and are in an inclined state.

[0045] A lifting screw, which is threadedly connected to the track lifting frame and is equipped with a positioning disc that abuts against the moving block for positioning.

[0046] By adopting the above technical solution, when movement is required, the lifting screw rotates to move the positioning plate away from the moving block, and then the rotating gear rotates to move the rack down. The rack moves down and moves the limit frame and support rod down at the same time, so that the moving wheel rolls on the track surface. After the movement is completed, the lifting screw is turned to move the positioning plate to press against the moving block for positioning. Therefore, the moving block and the limit block cooperate to support and position the limit frame, thereby improving the stability of the limit frame when supporting the track, and also improving the convenience of adjustment and construction efficiency.

[0047] Then, the track lifting frame is transferred. After the transfer is completed, the rotating gear drives the limit frame and support rod to move up to their original positions, so that the track lifting frame is placed on the track floor. Then, the lifting screw is turned to drive the positioning plate to move. The movement of the positioning plate causes the lifting surfaces of the moving block and the limit block to press together for positioning, thereby driving the limit frame and support rod to move. At the same time, it also improves the support and positioning effect of the limit frame, and improves construction efficiency and labor input efficiency.

[0048] Optionally, step 3 involves transporting concrete using a transport assembly that moves along a track. The transport assembly starts construction from the column body furthest from the concrete loading point and then gradually moves towards the concrete loading point.

[0049] By adopting the above technical solution, the probability of vibration caused to the newly poured column body due to the movement of transport components is reduced, thereby improving the quality of column body pouring and construction quality.

[0050] Optionally, the transport component includes:

[0051] A transport vehicle that moves on a track via rollers;

[0052] A drive motor is mounted on the transport vehicle and connected to the rollers to drive the rollers to rotate.

[0053] By adopting the above technical solution, the drive motor starts and drives the roller to rotate, and the rotation of the roller drives the transport vehicle to move, thereby realizing the transportation of concrete.

[0054] In summary, this application includes at least one of the following beneficial technical effects:

[0055] When constructing on adjacent tracks, the support adjustment mechanism can be transferred and used nearby, and the transfer is also carried out in sections. While the transfer is being carried out, the construction on the previous track is also carried out simultaneously, thereby reducing the idle waiting time during the construction process, as well as reducing the number of material turnovers and the time spent, thus improving construction efficiency and labor input efficiency.

[0062] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0063] This application discloses a construction method for the integral track bed of a column-type inspection pit using the column skipping method.

[0064] Reference Figure 1 In this application, the rails 12 are spliced ​​together at intervals along the length of the rails 12 during installation. Adjacent rails 12 are fixed by fasteners. Fasteners are a common structure used in the installation of rails 12, and will not be described in detail here.

[0065] Reference Figure 1 and Figure 2 The construction method of the column-type inspection pit integral track bed skipping column method includes the following construction steps:

[0066] Step 1: Install support adjustment mechanism 3: Install multiple sets of support adjustment mechanisms 3 at intervals along the length of track 12 on the same track, and then install track 12 on the top of multiple sets of support adjustment mechanisms 3 for support. Adjacent tracks 12 are fixedly connected together by fasteners. Each set of support adjustment mechanisms 3 is provided with multiple sets at intervals along the length of track 12, and the number is at least three. At least one column body 11 to be poured corresponds to one support adjustment mechanism 3, and the support adjustment mechanism 3 is located on one side of the column body 11 to be poured along the length of track 12.

[0067] The column body 11 to be poured is divided into multiple column groups 1 along the length of the track 12. Each column group 1 includes at least two column bodies 11 or more. Multiple column groups 1 are set one-to-one with multiple support adjustment mechanisms 3, so that one support adjustment mechanism 3 corresponds to multiple column bodies 11.

[0068] Step 2: Coarse and fine adjustment: The support adjustment mechanism 3 is used to make coarse and fine adjustments to the position of the track 12.

[0069] Step 3: Segmented Construction: The pouring construction is carried out in segments, with each set of support adjustment mechanisms 3 corresponding to a column group 1 as a unit. During the column pouring construction, only one column body 11 in each column group 1 corresponding to each support adjustment mechanism 3 is constructed. Generally, the column body 11 closest to the support adjustment mechanism 3 is selected for construction. Reinforcing steel binding and formwork installation are carried out at the pouring point of the column body 11, and finally, the pouring construction is carried out. During construction, concrete is transported and poured by the transport component 2 moving on the track 12. The pouring construction starts with the column body 11 farthest from the concrete filling point, and then gradually moves towards the concrete filling point, thereby reducing the adverse effects of the transport component 2 on the column body 11 during transportation.

[0070] Reference Figure 1 and Figure 3 The transport component 2 includes a transport vehicle 21 and a drive motor 22. The transport vehicle 21 moves on the track 12 via multiple rollers 23. The multiple rollers 23 are rotatably mounted on the bottom of the transport vehicle 21 and roll on two tracks 12 respectively. The drive motor 22 is fixedly mounted on the bottom of the transport vehicle 21 and its output shaft is connected to the rollers 23. When the drive motor 22 is started, it drives the rollers 23 to rotate. The rotation of the rollers 23 drives the transport vehicle 21 to move, thereby transporting the concrete to the pouring site for pouring.

[0071] Step 4: Disassembly and assembly: After the concrete strength of the column body 11 reaches the standard, disassemble and reassemble the multiple support adjustment mechanisms 3 and transfer them to the subsequent track for installation and use.

[0072] Step 5: The previous stock continues to complete steps 3 and 4; at the same time, the subsequent stock completes steps 1-4.

[0073] Reference Figure 1 and Figure 2 Step 6: Using the completed column body 11 as support, then complete the construction of the remaining column bodies 11 in multiple column groups 1 until the construction of all track columns is completed.

[0074] Reference Figure 1 and Figure 4The support and adjustment mechanism 3 includes a track lifting frame 31, a limiting component 4, and an adjustment component 5. The track lifting frame 31 includes a horizontal track lifting beam 32 and four legs 33 fixedly installed on the lower surfaces of both ends of the track lifting beam 32. The four legs 33 are fixedly connected in pairs and vertically supported on the track surface. The length direction of the track lifting beam 32 is perpendicular to the length direction of the track 12. Two adjacent track lifting frames 31 are connected together by connecting components 8. Two connecting components 8 are provided at both ends of the track lifting frame 31, and both connecting components 8 are located between two adjacent track lifting frames 31. The connecting components 8 are used to fix the two adjacent track lifting frames 31 together for positioning and force distribution.

[0075] Two support legs 33 located at the same end of the track-raising beam 32 have insertion slots on their opposite side walls. The connecting assembly 8 includes two connecting blocks 81, two connecting screws, and a connecting rod 82. The two connecting blocks 81 are respectively inserted into the insertion slots of the two support legs 33. The two connecting screws are fixedly installed on the ends of the two connecting blocks 81 away from the support legs 33, and the connecting screws are in a horizontal state. Both ends of the connecting rod 82 have threaded grooves that are threaded to the connecting screws. The two connecting screws are threaded into the threaded grooves, and the two connecting blocks 81 are pressed against the ends of the connecting rod 82 for positioning. The connecting rod 82 can be customized according to different lengths and curvatures, so that two adjacent track-raising frames 31 at different positions and angles can be connected together, improving the convenience of connection.

[0076] Reference Figure 1 and Figure 4 The limiting component 4 includes two fixed posts 41, a limiting frame 42, and two limiting tubes 43. The two fixed posts 41 are fixedly installed on both ends of the track lifting beam 32 and extend vertically above the track lifting beam 32. The limiting frame 42 has vertical limiting holes at both ends. The limiting frame 42 slides and is fitted onto the two fixed posts 41 through the two limiting holes. The limiting frame 42 is located above the track lifting frame 31. The middle part of the limiting frame 42 is bent to form an upwardly protruding limiting part 45. When the limiting frame 42 moves to its highest position, the top of the fixed post 41 is located in the limiting hole.

[0077] Two limiting tubes 43 are fixedly installed on the upper surfaces of the two limiting frames 42 at both ends, and the two limiting tubes 43 are respectively aligned with the axes of the two fixed columns 41. At the same time, the top of the limiting tube 43 is flush with the upper surface of the limiting part 45, and the fixed column 41 can slide through into the limiting tube 43 for guidance. The two ends of the limiting part 45 and the two limiting tubes 43 form a limiting space 44. The two rails 12 are placed on the upper surface of the limiting frame 42 and located in the two limiting spaces 44. The limiting space 44 is used to limit the rails 12.

[0078] Reference Figure 4 and Figure 5The adjustment assembly 5 is set on the track beam 32 and is used to adjust the position of the track 12. The adjustment assembly 5 includes an adjustment cylinder 51, two adjustment screws 52, and two push blocks 53. The adjustment cylinder 51 is detachably installed on the side wall of the limit frame 42 by screws, and the adjustment cylinder 51 is located below the limit space 44. The adjustment cylinder 51 is in a horizontal state and its axis is perpendicular to the length direction of the track 12. At the same time, an adjustment plate is coaxially fixedly installed on the inner side wall of the adjustment cylinder 51 at the middle position of the adjustment cylinder 51. One end of each of the two adjustment screws 52 is coaxially rotatably installed on the opposite side walls of the two adjustment plates, and the ends of the two adjustment screws 52 away from the adjustment plates extend to the outside of the adjustment cylinder 51. The two push blocks 53 are slidably installed on the inner side walls of the two adjustment cylinders 51, and the two push blocks 53 are threadedly connected to the two adjustment screws 52 and are located at the two tracks 12. Two vertical push plates 54 are fixedly installed on the upper surface of each of the two push blocks 53. The two push plates 54 are located on both sides of the track 12 and are used to push the track 12 to move.

[0079] When the position needs to be adjusted, the adjusting screw 52 is turned to rotate and drive the push block 53 to move. The movement of the push block 53 drives the two push plates 54 to move. One of the push plates 54 presses against the track 12 and pushes the track 12 to move. When the reverse adjustment is needed, the adjusting screw 52 is reversed, so the other push plate 54 can push the track 12 to move in the opposite direction. Thus, the position of the two tracks 12 can be adjusted by rotating the two adjusting screws 52, which improves the convenience of adjustment.

[0080] The track lifting frame 31 is equipped with multiple movable components 6 for easy movement. Two movable components 6 are spaced apart and located at both ends of the track lifting beam 32. The movable component 6 includes a support rod 61 and a support wheel 62. Two support rods 61 are provided and are vertically slidably installed on two support legs 33 respectively. The top ends of the two support rods 61 are connected together by a fixed crossbar 63. Two support wheels 62 are provided and are rotatably installed on the bottom ends of the two support rods 61 respectively. The support wheels 62 are used to drive the track lifting frame 31 to move.

[0081] Reference Figure 4 and Figure 5The track lifting frame 31 is equipped with a lifting assembly 7 that drives the limiting frame 42 and multiple support rods 61 to move vertically simultaneously. When the lifting assembly 7 is activated, it drives the multiple support rods 61 and support wheels 62 to move downward. At the same time, the limiting frame 42, limiting tube 43 and adjusting assembly 5 also move downward. The track 12 does not move because it is supported by the column body 11, so that the multiple support wheels 62 are supported on the track floor and the four support legs 33 are detached from the track floor. At the same time, the track 12 is located above the limiting space 44 and the four push plates 54 are located below the track 12, so that the track 12 is detached from the limiting space 44 and the four push plates 54. Therefore, the track lifting frame 31, the limiting assembly 4 and the adjusting assembly 5 will not come into contact with the track 12 when moving horizontally, thereby realizing the transfer of the track lifting frame 31, the limiting assembly 4 and the adjusting assembly 5 to the subsequent track.

[0082] After the transfer is completed, the lifting component 7 is activated, which drives the support rod 61 and the limiting frame 42 to move upward, so that the four support legs 33 are placed on the track ground for support. The upward movement of the limiting frame 42 causes the limiting space 44 and the adjusting component 5 to move upward at the same time, and then the track 12 can be laid. The track 12 is placed on the limiting frame 42 and located on the limiting space 44 for support. The push plate 54 can be moved to adjust the position of the two tracks 12.

[0083] The lifting assembly 7 includes a rack 71, a gear 72, a moving block 73, a limiting block 74, and a lifting screw 75. Two racks 71 are provided and located at both ends of the limiting frame 42. The top end of the rack 71 is fixedly installed on the lower surface of the limiting frame 42, while the bottom end of the rack 71 passes through the upper surface of the fixed crossbar 63 and extends to the bottom of the fixed crossbar 63. At the same time, the rack 71 and the fixed crossbar 63 are fixedly connected together. Horizontal rotating rods 76 are rotatably installed on the four support legs 33 located at both ends of the lifting beam 32. The rotating rods 76 are located below the fixed crossbar 63 and extend horizontally to the two racks 71. Two gears 72 are provided and are keyed to the rotating rods 76. The two gears 72 mesh with the two racks 71 respectively.

[0084] The movable block 73 is horizontally slidably installed on the upper surface of the lifting beam 32, and the sliding direction of the movable block 73 is perpendicular to the sliding direction of the limiting frame 42. The limiting block 74 is fixedly installed on the lower surface of the limiting part 45, and both the limiting block 74 and the movable block 73 have inclined and fitting lifting surfaces 77. An mounting plate 78 is fixedly installed on the upper surface of the lifting beam 32 and on one side of the movable block 73. The mounting plate 78 and the adjusting cylinder 51 are located on both sides of the lifting beam 32. The lifting screw 75 passes horizontally through the mounting plate 78. The mounting plate 78 extends to the side wall of the movable block 73 away from the movable block 73. The lifting screw 75 is threadedly connected to the mounting plate 78 and a positioning plate 79 is fixedly installed at the end near the movable block 73. The height of the lifting surface 77 at the end near the lifting screw 75 is higher than the height of the end away from the lifting screw 75. Therefore, the movable block 73 moves towards the side near the lifting screw 75 under the gravity of the limiting frame 42, the track 12 and the limiting block 74, so that the positioning plate 79 presses against the movable block 73 for positioning.

[0085] Reference Figure 4 and Figure 5 When movement is required, the lifting screw 75 is turned to move the positioning plate 79 away from the moving block 73. Then, the rotating rod 76 is rotated to drive the two gears 72 to rotate. The rotation of the gears 72 causes the limit frame 42, the adjusting component 5, and the support rod 61 to move downwards simultaneously. When movement is required, the rotation of the gears 72 causes the limit frame 42, the adjusting component 5, and the support rod 61 to move upwards simultaneously. After the upward movement is completed, the lifting screw 75 is turned to drive the positioning plate 79 to push the moving block 73 closer to the limit block 74, so that the lifting surfaces 77 of the limit block 74 and the moving block 73 are tightly attached together for positioning, thereby achieving the support and positioning of the limit frame 42.

[0086] The working principle of this application embodiment is as follows:

[0087] First, multiple sets of support adjustment mechanisms 3 are installed at intervals along the length of track 12 on the first track. Then, two tracks 12 are installed on the limiting frame 42 and located within two limiting spaces 44. The two adjacent spliced ​​tracks 12 are connected together by fasteners. Then, the adjusting screw 52 is rotated to drive the push plate 54 to move. The push plate 54 is moved to adjust the position of the two tracks 12. After the adjustment is completed, the construction is carried out in sections with the column corresponding to one set of support adjustment mechanisms 3 as the unit. At the same time, only one of the multiple column bodies 11 corresponding to one support adjustment mechanism 3 is constructed.

[0088] Reinforcing steel binding and formwork installation are carried out at the pouring point, followed by concrete transportation and pouring. Once the concrete strength of the column body 11 reaches the standard, a set of support adjustment mechanisms 3 that have completed the column construction are disassembled, transported, and installed on subsequent tracks for use. Then, the segmented construction and disassembly of the previous track are completed, and subsequent tracks are constructed in the same way as the previous track. Finally, the completed column body 11 is used as support to complete the construction of the remaining column bodies 11 on a track, until the construction on all tracks is completed. This improves the convenience of construction material turnover, the rationality of labor allocation, construction efficiency and labor input efficiency, and reduces construction costs.

[0089] When movement is required, turning the lifting screw 75 moves the positioning plate 79 away from the moving block 73. Then, rotating the lever 76 moves the limiting frame 42, the adjusting component 5, and the support rod 61 downwards simultaneously, causing the support wheel 62 to roll on the track surface, while the four support legs 33 detach from the track surface. At the same time, the track 12 disengages from the limiting space 44 and the four push plates 54. Next, turning the lifting screw 75 moves the positioning plate 79 to press against the moving block 73 to position the support wheel 62. Then, the track lifting frame 31 can be pushed to the designated position. 76 drives the limit frame 42, adjustment component 5 and support rod 61 to move upward simultaneously, so that the four support legs 33 are placed on the track ground for support, while the limit frame 42 and push plate 54 move upward to their original positions. Then, the lifting screw 75 is turned to make the lifting surfaces 77 on the limit block 74 and the moving block 73 stick together tightly, and the positioning plate 79 presses against the moving block 73 for positioning. This realizes the movement and installation of the support adjustment mechanism 3, which improves the convenience of transportation, improves the efficiency of construction and labor input, and reduces construction costs.

[0090] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
