[0002] The construction of subway stations is an important part of subway lines. The traditional all-concrete cast-in-place method can no longer meet the current requirements of efficient construction. There is an urgent need for a technical solution that can achieve fast, efficient and high-quality construction of superimposed subway stations.

[0003] For open-cut construction, gantry cranes can be used to lift components, or assembly trolleys can be used for assembly. However, in some complex environments, existing trolleys cannot directly assemble side walls, resulting in low efficiency. Furthermore, in stations with steel purlins or concrete beams, existing trolleys are incapable of assembling side walls.

DETAILED DESCRIPTION

[0026] This embodiment provides a construction method for a composite subway station, suitable for assembling composite subway stations using an assembly trolley, which can improve construction efficiency and shorten the construction period. The system can assemble single-story stations, double-story stations, three-story stations, four-story stations, etc.

[0027] A composite subway station consists of side walls, central columns, longitudinal beams, and a roof slab. The side walls and central columns are vertically distributed on both sides of the station, the longitudinal beams are located between two adjacent central columns, and the roof slab is located between the side walls and longitudinal beams.

[0028] For stations with two or more floors, the roof is divided into the middle roof located on the lower floor and the roof located on the upper floor; the longitudinal beams are divided into the middle longitudinal beams located on the lower floor and the top longitudinal beams located on the upper floor.

[0029] Figure 1 The figure shows a double-deck station. The superimposed subway station includes: side wall blocks 91, center columns 92, center top plates 93, top plates 94, center longitudinal beams 95, top longitudinal beams 96, and bottom plates 97. During the construction process, the bottom plate 97 of the platform and the bottom longitudinal beam 98 located in the middle of the bottom plate 97 are cast first. The longitudinal direction is the length of the platform and also the direction of travel. Along the longitudinal direction, multiple side wall blocks 91 are spliced in sequence to form the side walls, multiple center columns 92 are arranged at intervals, and multiple center longitudinal beams 95 are spliced in sequence, and the center longitudinal beams 95 are overlapped on two adjacent center columns 92. The center top plates 93 are overlapped between the side wall blocks 91 and the center longitudinal beams 95 in the transverse direction, and multiple center top plates 93 are spliced in sequence in the longitudinal direction. The above-mentioned side wall blocks 91, center columns 92, center longitudinal beams 95, and center top plates 93 constitute the lower structure of the station. After the construction of the lower structure is completed, the upper structure of the station begins to be built.

[0030] In the station's upper structure, upper center columns 92 are spaced longitudinally above the center longitudinal beams 95, and top longitudinal beams 96 are installed between adjacent upper center columns 92. Upper side wall blocks 91 are sequentially arranged on top of the lower side wall blocks 91, and top panels 94 are installed between the upper side wall blocks 91 and the top longitudinal beams 96. The top panels 94 are sequentially spliced longitudinally.

[0031] Figure 2 The station shown here is a three-story station. Similar to a two-story station, the station is divided into a top structure, a middle structure, and a bottom structure. The bottom structure is the same as the lower structure in a two-story station, while the middle and top structures refer to the upper structures in a two-story station, respectively.

[0032] like Figure 3As shown, the assembly trolley 10 is used to construct the lower structure. After the construction is completed or after the construction meets certain conditions, the assembly trolley 10 is used to construct the upper structure.

[0033] like Figure 4 As shown, for the above-mentioned composite station, the construction method provided in this embodiment includes: Step 101: pouring to form the station floor.

[0034] Step 102: Cast a longitudinal bottom beam in the middle of the station floor to form a longitudinally extending bottom beam, which divides the station floor into two station areas.

[0035] In specific implementation, when the length of the cast-in-place base plate exceeds ten rings, the bottom longitudinal beams can be installed on the base plate. The longitudinal direction of the station is the extension direction of the running track.

[0036] Step 103: Install running tracks on the station floors of the two station areas respectively, with the running tracks extending in the longitudinal direction.

[0037] Running tracks can be installed in both station areas.

[0038] Step 104: Install the first center column at the longitudinal start of the station. The center column is fixed to the bottom longitudinal beam by grouting.

[0039] In the absence of steel temporary beams above the construction area, the first center column can be lifted by a gantry crane to the installation location of the station floor.

[0040] In this embodiment, the center column is specifically installed on the bottom longitudinal beam and fixed to the bottom longitudinal beam by grouting.

[0041] Step 105: Install and debug the first assembly trolley and the second assembly trolley on the running tracks of the two station areas respectively.

[0042] While the center column is being grouted and fixed, the assembly trolley is installed and debugged on the running track.

[0043] The first assembling trolley and the second assembling trolley can work in parallel or in sequence. The bottoms of the first assembling trolley and the second assembling trolley are both provided with running wheels, which are installed on corresponding running tracks and can walk longitudinally along the running tracks.

[0044] Step 106: hoist the side wall blocks onto the first assembly trolley and the second assembly trolley respectively. The first assembly trolley and the second assembly trolley respectively carry the side wall blocks to the installation position along the running track, and install the side wall blocks on both sides of the station accordingly.

[0045] In the absence of steel temporary beams at the top of the construction area, the side wall blocks can be lifted onto the corresponding assembly trolley by a gantry crane, and then the side wall blocks can be carried to the installation location by the assembly trolley for installation.

[0046] When there is a steel temporary beam at the top of the construction area, an open-air opening is provided at one end of the construction area. The side wall blocks are lifted onto the assembly trolley through a gantry crane at the open-air opening, and then the assembly trolley carries the side wall blocks to the installation position for installation.

[0047] In this step, the first assembly trolley and the second assembly trolley can successively lift the side wall blocks through the gantry crane, and then transport and assemble them by self-propelled vehicles. Figure 5 A structural schematic diagram is shown in which the first assembly trolley located on the left and the second assembly trolley located on the right are respectively installed with the side wall blocks 91.

[0048] Step 107: After assembling at least three side wall blocks on at least one side, the first assembly trolley or the second assembly trolley installs the second center column in place and fixes it to the bottom longitudinal beam by grouting.

[0049] Each assembly trolley sequentially assembles the side wall blocks in the longitudinal direction. After at least three side wall blocks are assembled, the second center column is installed in place.

[0050] Alternatively, the number of center columns can be adjusted based on the width of the side wall blocks or the spacing between adjacent center columns. For example, after assembling at least six side wall blocks, the second center column is installed. The second center column is also installed on the station floor and secured with grouting.

[0051] When there is no steel temporary beam at the top of the construction area, the center column can be lifted and installed by a gantry crane.

[0052] When a steel temporary beam is provided on the top of the construction area, the center column can be carried and assembled by the first assembly trolley or the second assembly trolley, or by an additional center column mounting bracket.

[0053] Figure 5 It is also shown that the middle longitudinal beam 95 is carried on the first assembly trolley, and the middle column 92 is carried on the second assembly trolley. Figure 6 The second assembly trolley is shown installing the center column 92. Figure 6 The first assembly trolley in the assembly is assembling the side wall block 91 on the left side.

[0054] Step 108: The first assembly trolley or the second assembly trolley installs a longitudinal beam between the tops of two adjacent center columns.

[0055] After installing the two center columns, install the longitudinal beam between the tops of the two adjacent center columns. For lower-level stations, install the center longitudinal beam between the two center columns.

[0056] When there is a steel temporary beam at the top of the construction area, the longitudinal beam can be carried to the installation position by the first assembly trolley or the second assembly trolley and overlapped on two adjacent middle columns.

[0057] Figure 7 A schematic diagram of the installation of the longitudinal beam 95 on the first assembly trolley located on the left is shown.

[0058] Step 109: The first assembly trolley and the second assembly trolley each sequentially install at least three top panels between the assembled side wall blocks and the longitudinal beams.

[0059] After the side wall blocks and longitudinal beams at corresponding positions are assembled, a top plate is installed between the side wall blocks and the longitudinal beams. The top plate extends laterally and overlaps between the side wall blocks and the top ends of the longitudinal beams.

[0060] In this embodiment, the number of top plates can be determined based on the width of the side wall blocks, the width of the top plate, and the length of the longitudinal beams. In this embodiment, at least six top plates can be sequentially installed between the assembled side wall blocks and the longitudinal beams before the side wall blocks are installed.

[0061] Figure 8 A structural schematic diagram showing the first assembly trolley and the second assembly trolley respectively installing the middle top plate 93 is shown.

[0062] Step 110 , repeat the above steps to install the center column, side wall blocks, longitudinal beams and top plate using the first assembly trolley and the second assembly trolley.

[0063] Based on the above, every time six side wall blocks are installed continuously, a central column and longitudinal beam are installed, and then six top plates are installed.

[0064] The technical solution provided in this embodiment is to cast and form the station floor; cast a bottom longitudinal beam extending in the longitudinal direction in the middle of the station floor, and the bottom longitudinal beam divides the station floor into two station areas; install running tracks on the station floors of the two station areas respectively, and the running tracks extend in the longitudinal direction; install the first central column at the starting end of the longitudinal direction of the station, and the central column is fixed to the bottom longitudinal beam by grouting; install and debug the first assembly trolley and the second assembly trolley on the running tracks of the two station areas respectively; hoist the side wall blocks onto the first assembly trolley and the second assembly trolley respectively, and the first assembly trolley and the second assembly trolley each carry the side wall blocks to the installation position along the running tracks. , install the side wall blocks on both sides of the station accordingly; after assembling at least three side wall blocks on at least one side, the first assembly trolley or the second assembly trolley installs the second center column in place and fixes it with the bottom longitudinal beam by grouting; the first assembly trolley or the second assembly trolley installs the longitudinal beam between the tops of two adjacent center columns; the first assembly trolley and the second assembly trolley each install at least three top plates in sequence between the assembled side wall blocks and the longitudinal beam; repeat the above steps and use the first assembly trolley and the second assembly trolley to install the center column, side wall blocks, longitudinal beams and top plates, thereby realizing the assembly of the composite station using two assembly trolleys with high assembly efficiency.

[0065] During the installation of the second center column and longitudinal beam by the first and second assembly trolleys, one assembly trolley can transport and assemble the center column and longitudinal beam. Alternatively, the first assembly trolley can install the center column while the second assembly trolley installs the longitudinal beam. Specifically, while the first assembly trolley is installing the center column, the second assembly trolley can go to the open-air opening to receive the longitudinal beam, then transport the longitudinal beam to its proper position and attach it to the two adjacent center columns. The coordination of the two assembly trolleys significantly improves construction efficiency.

[0066] For double-deck stations or stations with three or more floors, after the lower level is constructed according to the above steps, the following plan is used to construct upwards: After the roof is installed, upper running tracks are installed on the upper surfaces of the roofs of the two station areas, and the running tracks extend longitudinally along the station.

[0067] Install and debug the first assembly trolley and the second assembly trolley on the upper layer on the running track.

[0068] The first center column of the upper floor is installed above the bottom longitudinal beam. The first center column is also installed at the longitudinal beginning of the station.

[0069] The side wall blocks are hoisted onto the first assembly trolley and the second assembly trolley respectively. The first assembly trolley and the second assembly trolley respectively carry the side wall blocks to the installation position along the running track, and the side wall blocks are installed correspondingly on both sides of the upper level of the station.

[0070] Figure 9 The schematic diagram of the structure of the first assembly trolley and the second assembly trolley respectively installing the upper side wall block 91 is shown. Figure 9 The first assembling trolley carries the top longitudinal beam 96 , and the second assembling trolley carries the middle column 92 .

[0071] After at least three side wall blocks are assembled on at least one side, the first assembly trolley or the second assembly trolley installs the second center column in place, such as Figure 10 shown.

[0072] The first assembly trolley or the second assembly trolley installs the longitudinal beam between the tops of the middle columns of two adjacent upper layers. Figure 10 In the process, the first assembly trolley installs the top longitudinal beam 96 into place.

[0073] The first assembly trolley and the second assembly trolley each sequentially install at least three top plates between the assembled upper side wall blocks and the longitudinal beams.

[0074] Repeat the above steps and use the first assembly trolley and the second assembly trolley to install the center column, side wall blocks, longitudinal beams and top plate of the upper layer.

[0075] According to the above scheme, the construction of stations with two or more floors can be realized.

[0076] Figure 11 Showing the installation of upper level side wall blocks 91 of a three-level station, Figure 12 The installation of the upper center column 92 and top longitudinal beam 96 of the three-story station is shown. Figure 13 The installation of the top plate of the three-story station 94 is shown.

[0077] Based on the above technical solution, after the last side wall panel is installed in the two station areas, the first assembly trolley and the second assembly trolley are dismantled and lifted out at the longitudinal end of the station, and the last top panel in each station area is lifted to the installation position by a gantry crane and installed.

[0078] When a gantry crane can be used above the construction area, the center column, top plate and longitudinal beam are all lifted by the gantry crane, and the first assembly trolley and the second assembly trolley can correspondingly assist in carrying and assembling at least one of the center column, top plate and longitudinal beam.

[0079] When a steel temporary beam is installed above the construction area, the center column, top plate and longitudinal beam are lifted to the first assembly trolley and the second assembly trolley by a gantry crane at the longitudinal end of the station. The first assembly trolley and the second assembly trolley carry the center column, top plate and longitudinal beam to the corresponding installation positions along the running track and assemble them.

[0080] The first assembly trolley and the second assembly trolley can adopt the same structure, that is, both include a frame, a wheel-rail running device, a side wall mounting device, a longitudinal beam mounting device and a top plate mounting device.

[0081] Alternatively, the first assembly trolley and the second assembly trolley use the same frame, wheel-rail running device, side wall mounting device, and roof mounting device to install the side wall blocks and roof panels in their respective station areas. One of the assembly trolleys is provided with a longitudinal beam mounting device for installing the longitudinal beam and center column.

[0082] Alternatively, another center column installation device may be used to install the center column.

[0083] On the basis of the above technical solution, this embodiment provides an assembly trolley, and implements the above steps based on the assembly trolley. Figures 14 to 21 As shown, the station assembly trolley provided in this embodiment includes: a wheel-rail running device 1, a frame 2 and a side wall mounting device 3.

[0084] After the baseplate 97 is formed, temporary tracks are laid on the baseplate 97, specifically on both sides of the bottom longitudinal beams 98. The tracks extend longitudinally. The wheel-rail running gear 1 is mounted on the bottom of the frame 2 and runs along the tracks on the baseplate 97, allowing the trolley to be moved longitudinally and assembled step by step. The frame 2, mounted above the wheel-rail running gear 1, serves as the trolley's primary framework, upon which all trolley components are mounted.

[0085] The side wall mounting device 3 is mounted on the vehicle frame 2. A gantry crane is used to hoist the side wall blocks 91 onto the side wall mounting device 3. The side wall mounting device 3 secures the side wall blocks 91 and moves them to the side wall mounting position for assembly. During construction, the trolley moves longitudinally, assembling each side wall block 91 sequentially.

[0086] In the above steps, the first assembly trolley or the second assembly trolley carries the side wall blocks to the installation position along the running track, and installs the side wall blocks correspondingly on both sides of the station, including: the assembly trolley travels along the running track through the wheel-rail running device to carry the side wall blocks to the installation position; and the side wall blocks are installed correspondingly on both sides of the station through the side wall installation device.

[0087] The side wall installation device 3 includes a side wall support mechanism 31, a side wall installation mechanism 32, and a side wall fine-adjustment mechanism 33. The side wall support mechanism 31 is located below the vehicle frame 2 and extends toward one side of the vehicle frame 2, specifically toward the direction of the side wall to be assembled. The gantry crane hoists the side wall block 91 onto the side wall support mechanism 31, which supports the side wall block 91 from below.

[0088] The side wall mounting mechanism 32 is provided on the top of the vehicle frame 2. When the gantry crane lifts the side wall block 91 onto the side wall supporting mechanism 31, the side wall mounting mechanism 32 is connected to the side wall block 91. The side wall mounting mechanism 32 is used to apply a driving force to the side wall block 91 to move the side wall block 91 for assembly.

[0089] The side wall fine adjustment mechanism 33 is disposed at the lower portion of the vehicle frame 2 and is used to apply a force to the lower portion of the side wall block 91 to finely adjust the pitch angle of the side wall block 91 .

[0090] In the above steps, the side wall blocks are installed through the side wall installation device, including: supporting the side wall blocks from the bottom through the side wall supporting mechanism; applying a driving force to the side wall blocks through the side wall installation mechanism to move the side wall blocks for assembly; and applying a force to the lower part of the side wall blocks through the side wall fine-tuning mechanism to finely adjust the pitch angle of the side wall blocks.

[0091] The above scheme supports the side wall blocks through the side wall supporting mechanism, and the side wall installation mechanism applies a driving force to the side wall blocks to move the side wall blocks for assembly. The side wall fine-adjustment mechanism is used to finely adjust the pitch angle of the side wall blocks, which can ensure the stable installation of the side wall blocks and improve the accuracy, thereby improving the assembly quality.

[0092] Based on the above technical solution, the side wall mounting device 3 further includes a side wall clamping mechanism 34. The side wall clamping mechanism 34 is arranged in the middle of the vehicle frame 2, extending from both sides of the side wall block 91 to the side of the side wall block 91 facing away from the trolley, and applies a clamping force to the side wall block 91 to prevent the side wall block 91 from tipping over during movement.

[0093] In the above steps, the side wall block is installed by the side wall installation device, which also includes: the side wall clamping mechanism extends from both sides of the side wall block to the side of the side wall block away from the trolley and applies a clamping force to the side wall block.

[0094] For the side wall holding mechanism 34, this embodiment provides a specific example: Figure 17 As shown, the side wall clamping mechanism includes: at least one pair of clamping claws 341 and at least one clamping claw driver 342, and one clamping claw driver 342 is connected to one clamping claw 341 for driving the clamping claw 341 to move.

[0095] Specifically, one pair of claws 341, two pairs of claws 341, or three pairs of claws 341 may be used. When a pair of claws 341 is used, the claws 341 are located in the middle of the side wall block 91. When two or three pairs of claws 341 are used, the claws 341 are arranged vertically at intervals. This embodiment uses only one pair of claws 341 as an example.

[0096] The two claws 341 in a pair are spaced apart in the longitudinal direction, have the same height, and have space between them to accommodate the side wall block 91. The inner side of the claws 341 is provided with a groove for the side surface of the side wall block 91 to be embedded.

[0097] One end of the gripper actuator 342 is connected to one gripper 341, and the other end is fixed to the vehicle frame 2. The gripper actuator 342 is used to drive the grippers 341 to swing, moving the two grippers 341 toward or away from each other. When the two grippers 341 approach each other, they grip the side wall block 91 from both sides; when the two grippers 341 move away from each other, they release the side wall block 91. The gripper actuator 342 can be a drive mechanism such as a pneumatic cylinder, a hydraulic cylinder, or a motor.

[0098] The side wall clamping mechanism applies a clamping force to the side wall block, including: a clamping claw driver drives two clamping claws to extend from both sides of the side wall block to the side of the side wall block away from the trolley, and makes the two clamping claws approach each other to apply a clamping force to the side wall block.

[0099] This embodiment provides an implementation method in which the side wall mounting device 3 is located on one side of the vehicle frame 2, specifically, near the side wall to be assembled. A side wall block 91 is hoisted onto the side wall mounting device 3 by a gantry crane. The side wall mounting mechanism 32 is then moved laterally, longitudinally, and vertically into position for assembly.

[0100] This embodiment provides a specific example of the side wall supporting mechanism 31. The side wall supporting mechanism 31 includes at least two side wall supporting beams 311 extending in the transverse direction. The at least two side wall supporting beams 311 are spaced apart in the longitudinal direction. A side wall block 91 is placed on each of the side wall supporting beams 311, and each side wall supporting beam 311 supports the side wall block 91.

[0101] The side wall supporting beam 311 may be a steel beam with a U-shaped cross section, an I-shaped steel beam, or a steel beam of other shapes.

[0102] Furthermore, the upper surface of the side wall supporting beam 311 is flat, and the upper surfaces of the side wall supporting beams 311 are at the same height to adapt to the bottom shape of the side wall block 91 .

[0103] The above scheme of using at least two side wall supporting beams 311 to be spaced apart leaves a gap between two adjacent side wall supporting beams 311 for easy observation and operation. Of course, in addition to the above scheme, supporting plates can also be used to replace the above side wall supporting beams 311.

[0104] This embodiment provides a method for fine-adjusting the side wall 33. The mechanism 33 includes a fine-adjusting connector 331 and a fine-adjusting actuator 332. One end of the fine-adjusting actuator 332 is connected to the vehicle frame 2, and the other end is connected to the fine-adjusting connector 331. The fine-adjusting connector 331 is connected to the side wall block 91. The fine-adjusting actuator 332 is used to drive the fine-adjusting connector 331 to move laterally, acting on the lower portion of the side wall block 91, thereby finely adjusting the pitch angle of the side wall block 91 to meet the requirements of side wall assembly.

[0105] Fine-adjustment actuator 332 can be a pneumatic cylinder, hydraulic cylinder, or other actuator. In this embodiment, a hydraulic cylinder is used as an example. The end of fine-adjustment connector 331 is bolted to sidewall block 91. Two sidewall fine-adjustment mechanisms 33 are spaced apart and work together to fine-tune sidewall block 91, front to back, and left to right. The H-shaped steel at the bottom of sidewall block 91 aligns with the groove in the base plate. Once aligned, sidewall block 91 is lowered into the groove.

[0106] On the basis of the above technical solution, the side wall mounting device 3 further comprises: a side wall mounting frame 35, which is arranged on one side of the vehicle frame 2. The side wall mounting frame 35 is a hollow structure, which is formed by connecting vertical beams, longitudinal beams and transverse beams to form a hollow frame structure.

[0107] The side wall fine adjustment mechanism 33 is located within the interior space of the side wall mounting frame 35. The fine adjustment driver 332 in the side wall fine adjustment mechanism 33 can be fixed to the side wall mounting frame 35 or to the vehicle frame 2. The side wall fine adjustment mechanism 33 extends laterally and can be extended or retracted from the interior space of the side wall mounting frame 35.

[0108] The side wall supporting mechanism 31 is located below the side wall mounting frame 35 and extends out of the side wall mounting frame 35. One side surface of the side wall block 91 is in contact with the side wall mounting frame 35. The side wall holding mechanism 34 is located above the side wall mounting frame 35, and the holding claw 341 extends out of the side wall mounting frame 35 to hold the side wall block 91.

[0109] On the basis of the above technical solution, this embodiment provides an implementation method of a side wall mounting mechanism 32: Figure 18 As shown, the side wall installation mechanism includes: a side wall longitudinal moving frame 321, a side wall lifting frame 322, a side wall transverse moving frame 323, a transverse moving arm 324, a longitudinal moving driver 325, a vertical driver 326 and a transverse moving driver 327.

[0110] The sidewall longitudinal shift frame 321 is mounted on the vehicle frame 2 and extends longitudinally. The sidewall lifting frame 322 is slidably mounted on the sidewall longitudinal shift frame 321 and is movable longitudinally relative to the sidewall longitudinal shift frame 321. A longitudinal shift driver 325 is mounted on the sidewall longitudinal shift frame and connected to the sidewall lifting frame 322 to provide a driving force for longitudinal movement.

[0111] The side wall traverse frame 323 is slidably mounted on the side wall lifting frame 322 and is movable vertically relative to the side wall lifting frame 322. The vertical actuator 326 is mounted on the side wall lifting frame 322 and is connected to the side wall traverse frame 323 to provide vertical driving force to the side wall traverse frame 323.

[0112] The traverse arm 324 is mounted on the sidewall traverse frame 323 and is slidable laterally relative to the sidewall traverse frame 323. A traverse driver 327 is mounted on the sidewall traverse frame 323 and connected to the traverse arm 324, providing lateral driving force to the traverse arm 324. The end of the traverse arm 324 is connected to the sidewall block 91. Through the coordinated action of these components, the sidewall block 91 is driven to move longitudinally, transversely, and vertically.

[0113] The side wall block 91 is placed on the side wall supporting mechanism 31, and the side wall holding mechanism 34 holds the side wall block 91 tightly. The trolley can drive the side wall block 91 to move longitudinally to realize the carrying. After moving into position, the side wall holding mechanism 34 releases the side wall block 91, and the side wall installation mechanism 32 drives the side wall block 91 to move horizontally, longitudinally and vertically to the assembly position for assembly. During this process, the position of the side wall block 91 can be finely adjusted by the side wall fine adjustment mechanism 33 so that the bottom end of the side wall block 91 is aligned with the assembly interface 20 (such as Figure 22 ).

[0114] After the side wall block 91 is installed, an adjustment rod for the ground-connected wall is installed on the top of the side wall block 91 to connect and fix the side wall 91 to the ground. Concrete can be poured between the side wall block 91 and the ground-connected wall.

[0115] Based on the above solution, the side wall lifting frame 322 can specifically include a lifting top plate 3221 and lifting legs 3222 disposed at the bottom of the lifting top plate 3221. There are four lifting legs 3222, with two lifting legs 3222 forming a set. A gap is left between the two sets of lifting legs 3222 to accommodate the side wall longitudinal displacement frame 321. The two sets of lifting legs 3222 are arranged on either side of the side wall longitudinal displacement frame 321. The gap between the lifting legs 3222 and the side wall longitudinal displacement frame 321 is only sufficient for relative sliding movement between the two. This solution improves the stability of the side wall mounting mechanism 32 and prevents it from tipping over.

[0116] The sidewall transverse frame 323 specifically includes a lifting slide beam 3231 and a transverse beam 3232. The lifting slide beam 3231 extends vertically and is telescopically disposed within the interior space of a lifting leg 3222. The transverse beam 3232 is connected to the top of each lifting slide beam 3231 and extends laterally. The transverse arm 324 is telescopically disposed within the interior space of the transverse beam 3232.

[0117] For structures with steel purlins or concrete waist beams on the side walls, the gantry crane cannot directly lift the side wall block 91 vertically downward onto the trolley due to the obstruction of the steel purlins or concrete waist beams. To address this problem, the trolley is further optimized in this embodiment, and the frame 2 can move laterally relative to the wheel-rail running device 1, which can supplement the lateral travel of the side wall block 91.

[0118] Figure 23 In the figure, two assembling trolleys are used to assemble the side wall blocks on both sides of the platform. In this embodiment, the positions of these two trolleys are used to assemble the concrete waist beam. Figure 23 As shown, the frame 2 moves about 1.5 m in the direction away from the side wall, and the side wall block 91 is lifted downwards onto the trolley by the gantry crane (as shown in FIG. Figure 23 The right trolley in the figure) During this process, the side wall block 91 can avoid the concrete waist beam 30. Specifically, the side wall block 91 is placed on the side wall support mechanism 31 and is clamped by the side wall clamping mechanism 34. At this time, the height of the side wall block 91 is lower than the concrete waist beam 30, and the gantry crane is withdrawn. The frame 2 then moves horizontally about 1.5m relative to the wheel-rail running device, close to the side wall (such as Figure 23 The right trolley in the middle continues to move about 1m to the right), and then the side wall blocks 91 are assembled through the side wall installation mechanism 32, which can solve the problem of the concrete waist beam being blocked. The trolley on the left is in the state of completing the splicing of the wall blocks on one side.

[0119] If it is a steel purlin, the frame moves 1 m in the horizontal direction, so that the side wall block 91 can be hoisted away from the steel purlin.

[0120] On the basis of the above technical solution, for the solution with steel temporary beams on the top of the construction area, the longitudinal beams, center columns and top plates can be transported and assembled by an assembly trolley. This embodiment also optimizes the above assembly trolley: The assembly trolley also includes a longitudinal beam installation device, which includes a mobile platform and a hoisting frame. In the above steps, the first or second assembly trolley carries the longitudinal beam along the running track to the corresponding installation location for assembly, including: securing the longitudinal beam using a connection portion provided at the outer end of the hoisting frame; using the wheel-rail running device to travel along the running track to carry the longitudinal beam to the installation location; and assembling the longitudinal beam by moving the mobile platform horizontally.

[0121] like Figures 24 to 26 As shown, a mobile platform 41 is mounted atop the vehicle frame 2 and is movable laterally relative to the vehicle frame. A hoisting frame 42 is positioned above the mobile platform 41, with space between the hoisting frame 42 and the mobile platform 41 to accommodate longitudinal beams. The outer ends of the hoisting frame 42 are provided with at least two connectors for temporarily connecting longitudinal beams. At an open-air opening, a gantry crane hoists a longitudinal beam (e.g., center longitudinal beam 95) and moves it to the area between the mobile platform 41 and the hoisting frame 42. The connectors on the hoisting frame 42 are then connected to the center longitudinal beam 95. After the connection is complete, the gantry crane is removed. A trolley, using a wheel-rail running mechanism, travels along tracks to carry the center longitudinal beam 95.

[0122] When moving to the target position, the mobile platform 41 extends horizontally toward the direction of assembling the middle longitudinal beam 95. After reaching the correct position, the middle longitudinal beam 95 is lowered and overlapped between two adjacent middle columns 92. The connection between the connecting part of the lifting frame 42 and the middle longitudinal beam 95 is removed to complete the assembly of the middle longitudinal beam 95.

[0123] Based on the above technical solution, the longitudinal beam installation device 4 further includes a longitudinal beam support frame 43. The longitudinal beam support frame 43 is arranged above the mobile platform 41 and extends vertically. A space for accommodating the longitudinal beam is left between the top of the longitudinal beam support frame 43 and the connection portion on the hanging frame 42.

[0124] Considering that the trolley travels a long distance, in order to reduce the risks in the lifting and traveling process, the longitudinal beam can be placed on the longitudinal beam support frame 43, and the longitudinal beam is supported by the longitudinal beam support frame 43.

[0125] The longitudinal beam support frame 43 can be formed by multiple rod-shaped mechanisms, which are arranged vertically, horizontally and along the longitudinal beam and connected to each other. It can support the weight of the longitudinal beam and ensure the stability of the longitudinal beam during the travel of the trolley.

[0126] Furthermore, the hanging frame 42 can move laterally relative to the mobile platform 41. When the lateral movement of the mobile platform 41 is limited, the hanging frame 42 can be further moved laterally to increase the movable travel of the longitudinal beam, thereby meeting the assembly requirements of the longitudinal beam.

[0127] The hanging frame 42 can also move vertically relative to the mobile platform 41 to accommodate longitudinal beams of varying thicknesses. For example, a vertical support 44 is vertically mounted on the mobile platform 41 or on the vehicle frame 2, and the hanging frame 42 is mounted on top of the vertical support 44. The hanging frame 42 can move up and down relative to the vertical support 44.

[0128] Regarding the hoisting frame 42, this embodiment provides an implementation method: the hoisting frame 42 includes a hoisting arm 421 and two auxiliary arms 422. The two auxiliary arms 422 are arranged parallel and side by side, extending in the horizontal direction and spaced apart in the longitudinal direction. The hoisting arm 421 is connected between the outer ends of the two auxiliary arms 422. The hoisting arm 421 is provided with a connecting portion 423 for connecting to the longitudinal beam. Specifically, the hoisting arm 421 and the two auxiliary arms 422 are connected to form a rectangular frame with one side open, and the open end is away from the location where the longitudinal beam is to be assembled. The hoisting arm 421 is close to the location where the longitudinal beam is to be assembled.

[0129] Based on the above solution, a sliding guide structure is provided between the auxiliary arm 422 and the top of the mobile platform 41, allowing the auxiliary arm 422 to move laterally relative to the mobile platform 41 via the sliding guide structure. The sliding guide structure can be installed at the top of the vertical support 44 and can be a slider and slide rail, or a slider and slide groove. A driving mechanism such as a hydraulic cylinder is used to provide lateral driving force to the auxiliary arm 422.

[0130] The connection portion 423 on the hoisting frame 42 can be a lifting ring, and at least two lifting rings are spaced apart along the length direction (i.e., longitudinal direction) of the hoisting arm 421 to meet the hoisting requirements of the longitudinal beam. The lifting rings can be connected to the longitudinal beam through ropes.

[0131] Alternatively, the connecting portion 423 may be a hook that is hooked on a ring at the top of the longitudinal beam.

[0132] The above technical solution enables the hoisting of longitudinal beams. During construction, the central column 92 in the center of the station is first assembled. Multiple central columns 92 are arranged in a longitudinally spaced sequence. A trolley is then used to transport the central longitudinal beam 95 to a position between two adjacent central columns 92. The central longitudinal beam 95 is hoisted using the hoisting frame 42 and moved horizontally between and above the two central columns 92. Once in position, the central longitudinal beam 95 is lowered and connected between the two adjacent central columns 92. A longitudinal tightening force is then applied to the central columns 92 to tighten the central longitudinal beam 95 longitudinally, completing the assembly of the longitudinal beams.

[0133] On the basis of the above technical solution, the longitudinal beam installation device 4 can also cooperate with the center column 92 to lift, transport and install. Specifically, a structure such as a lifting ring can be set on the top of the center column 92 and connected to the connection part on the lifting frame 42 to realize the lifting of the center column 92.

[0134] Furthermore, the mobile platform 41 is optimized so that the mobile platform 41 can support and fix the center column 92. Figure 19 As shown, the mobile platform 41 includes two parallel and side-by-side movable platforms 411 extending laterally. A space is left between the two movable platforms 411 to accommodate the center column 92. The center column 92 is placed between the two movable platforms 411. The movable platforms 411 are used to temporarily secure and transport the center column 92.

[0135] In the above steps, the first assembly trolley or the second assembly trolley carries the center column to the corresponding installation position along the running track and assembles it, including: fixing the center column by the moving platform; and moving along the running track by the wheel-rail running device to carry the center column to the installation position for assembly.

[0136] In the above steps, the assembly trolley carries the center column to the corresponding installation position along the running track and assembles it, including: fixing the center column by moving the platform; and moving the wheel-rail running device along the running track to carry the center column to the installation position for assembly.

[0137] In one specific embodiment, the cross-sections of the center column 92 and the top of the center column 92 are both rectangular, with the center cross-section length being shorter than the top cross-section length. The distance between the two movable platforms 411 is shorter than the top cross-section length of the center column 92, but longer than the center cross-section length of the center column 92. The center of the center column 92 then enters the gap between the two movable platforms 411 and becomes lodged between them, preventing it from falling downward. Thus, the two movable platforms 411 secure and support the center column 92.

[0138] Furthermore, a locking member 412 is provided at the outer end of the movable platform 411. A locking rod 413, longer than the distance between the two movable platforms, is employed, with its ends removably connected to the locking members 412 on the two movable platforms 411. The locking rod 413 prevents the center column 92 from moving outward, further improving reliability during transport and preventing the center column 92 from falling out of the gap between the two movable platforms 411.

[0139] In addition, a center column support surface can be provided on the upper surface of the end portion of the wheel-rail running device 1 corresponding to the longitudinal beam mounting device 4, and the bottom end of the center column 92 abuts against the center column support surface. The center column support surface can be concave to position the center column 92 and improve its stability.

[0140] Based on the above technical solution, the assembly trolley is further equipped with a roof panel installation device for carrying the roof panel and assembling it. The roof panel installation device includes a roof panel support bracket and a roof panel lifting and driving mechanism. In the above steps, the first or second assembly trolley carries the roof panel along the running track to the corresponding installation position for assembly, including: supporting the top portion with the roof panel support bracket; and traveling along the running track with a wheel-rail running device to carry the roof panel to the installation position for assembly.

[0141] like Figures 27 to 31 As shown, this embodiment also provides an implementation method of a roof installation device 5 , which includes a roof lifting frame 51 , a roof supporting frame 52 and a roof lifting drive mechanism 53 .

[0142] Among them, the top plate lifting frame 51 is set at the top of the frame 2. It can adopt multiple strip beams arranged in the horizontal, longitudinal and vertical directions to connect into a hollow frame structure, which can be welded to the top of the frame 2.

[0143] The roof support bracket 52 is mounted on the top of the roof lift 51 and is movable vertically relative to the roof lift 51. The roof support bracket 52 supports the roof. The roof panels mentioned below are described using the middle roof panel 93 as an example. Those skilled in the art can apply the technical solutions provided in this embodiment to assemble the roof panel 94.

[0144] The top plate lifting drive mechanism 53 is arranged between the top plate lifting frame 51 and the top plate supporting frame 52, and is used to provide a driving force for the vertical movement of the top plate.

[0145] During the construction process, the middle top plate 93 is hoisted onto the top plate support bracket 52 at the open-air opening at one end of the steel temporary beam by a gantry crane. The top plate support bracket 52 then supports the middle top plate 93. The trolley then moves along the track to the installation position. The top plate lifting drive mechanism 53 adjusts the height of the top plate support bracket 52 so that the middle top plate 93 above the top plate support bracket 52 is higher than the side wall blocks 91 and the middle longitudinal beam 95 on both sides. The trolley then continues to move toward the installed middle top plate 93 until it reaches the target position. The top plate lifting drive mechanism 53 is then activated to lower the top plate support bracket 52 and the middle top plate 93 until the ends of the middle top plate 93 overlap the side wall blocks 91 and the middle longitudinal beam 95, completing the assembly of the middle top plate 93.

[0146] Based on the above technical solution, this embodiment provides an implementation of a roof support bracket 52: the roof support bracket 52 includes two roof support beams 521. The two roof support beams 521 are arranged parallel and side by side, respectively, on either side of the roof lifting frame 51. The distance between the two roof support beams 521 is less than the length of the roof. The roof is placed on the two roof support beams 521, with the length of the roof perpendicular to the roof support beams 521.

[0147] Furthermore, the top plate lifting frame 51 can also move laterally relative to the vehicle frame 2 . During the assembly process, the top plate lifting frame 51 moves laterally to adjust the lateral position of the middle top plate 93 .

[0148] Furthermore, by installing an extrusion fixture 54 on the upper surface of the middle portion of the roof support beam 521, the extrusion fixture 54 can move relative to the roof support beam 521. An extrusion driver is installed on the roof support beam 521 and connected to the extrusion fixture 54 to apply a longitudinal driving force to the extrusion fixture 54. During the transport process, the middle roof panel 93 is placed on the extrusion fixture 54. During the assembly process, after the middle roof panel 93 is overlapped with the side wall blocks 91 and the middle longitudinal beam 95, the extrusion driver is activated, driving the extrusion fixture 54 to apply a longitudinal extrusion force to the middle roof panel 93, thereby compacting the newly assembled middle roof panel 93.

[0149] In the above steps, the first assembly trolley or the second assembly trolley carries the top plate to the corresponding installation position along the running track and assembles it, which also includes: applying a longitudinal driving force to the extrusion tooling through the extrusion drive component so that the extrusion tooling applies a longitudinal extrusion force to the top plate.

[0150] Sealing strips are embedded in the side surfaces of the middle top plates 93. When a longitudinal extrusion force is applied to the middle top plates 93, the sealing strips are tightly pressed between adjacent middle top plates 93, thereby improving the waterproof effect.

[0151] On the basis of the above technical solution, this embodiment also provides another method for transporting and installing the center column: using the center column mounting frame 6 to transport and assemble the center column 92.

[0152] like Figure 32 and Figure 33 As shown, the bottom of the center column mounting frame 6 is provided with running wheels, which can walk on the station floor. The top of the center column mounting frame 6 is provided with an opening that can accommodate the middle part of the center column 92, and the opening size is larger than the middle size of the center column 92 and smaller than the top size of the center column 92.

[0153] At the open-air opening, the gantry crane lifts the center column 92 and enters the center column mounting frame 6 from the opening. Since the top size of the center column 92 is large, it can be stuck on the center column mounting frame 6. The center column mounting frame 6 supports the center column 92 and can walk on the station floor to the installation position for installation.

[0154] In one embodiment, the center column mounting frame 6 includes two detachably connected center column brackets 61. Each center column bracket 61 is equipped with running wheels at its base, allowing each center column bracket 61 to travel on the floor. The center column brackets 61 are steel-frame structures composed of multiple connected steel beams. The tops of the two center column brackets 61 are detachably connected and form an opening.

[0155] During construction, a gantry crane hoists the center column 92 between the two center column brackets 61 at the open-air opening. The two center column brackets 61 are then brought close together and connected to form an opening, and the center column brackets 61 are locked into the opening. The center column mounting frame 6 then travels entirely on the baseplate, with the two center column brackets 61 positioned on either side of the bottom longitudinal beam to align the center column 92 with its installation position on the bottom longitudinal beam. Once the center column 92 is installed, the two center column brackets 61 are separated, each traveling on the baseplate and returning to the open-air opening to await the hoisting of the next center column 92.

[0156] The solution of providing two center column brackets 61 can reduce the difficulty of the center column entering the opening of the center column mounting frame 6, thereby improving efficiency. Moreover, the detachable connection of the two center column brackets 61 can adapt to center columns of different sizes, thereby meeting the needs of different stations and improving applicability.

[0157] A specific implementation method: The distance between the lower parts of the two center column brackets 61 is greater than the width of the bottom longitudinal beam of the station. The two center column brackets 61 can be symmetrically located on both sides of the bottom longitudinal beam, so that the center column is exactly aligned with the installation position, shortening the time for aligning the center column during construction, thereby improving construction efficiency.

[0158] Furthermore, a support platform 62 is provided on top of the center column bracket 61. A space is left between the support platforms 62 of the two center column brackets 61 to accommodate the center portion of the center column. Two center column stopper assemblies 63 are connected between the two support platforms 62. The two center column stopper assemblies 63 are spaced apart and form an opening with the two support platforms 62.

[0159] The center column limit assembly 63 may include a connecting rod and a connecting piece. A vertical connecting plate is provided on the supporting platform 62, and a hole is formed in the connecting plate. The end of the connecting rod is provided with an external thread, which passes through the hole in the connecting plate and is threadedly connected to the connecting piece.

[0160] On the basis of the above technical solution, before pouring the station floor, it also includes: constructing a ground-connected wall on the periphery of the construction area.

[0161] After completing the splicing of at least one side wall block, the method further includes: connecting the top of the side wall block to the top of the ground-connected wall using a connecting piece.

[0162] After all the side wall blocks are spliced together, the method further includes: pouring concrete between the side wall blocks and the ground-connected wall to firmly connect the side wall blocks and the ground-connected wall into one.

[0163] Based on the above technical solutions, this embodiment further provides a composite subway station, which is constructed using any of the above construction methods. The composite subway station provided by this embodiment has the same technical effects as the above construction methods.
