Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and in particular to a construction method of an outer frame vertical structure and a basement structure that interfere with foundation pit supports. Background Art

[0002] For super high-rise buildings, the construction period of their underground structures is relatively long, which often becomes a key factor restricting the construction period of the entire project. In order to shorten the construction period of the underground structures of super high-rise buildings, the vertical structure of the basement outer frame is generally constructed in sections of 2 to 3 floors. However, in order to ensure that the deformation control of the foundation pit project meets the requirements, its internal supports need to wait until the underground structure of the corresponding floor is completed before they can be removed. Therefore, at this time, the construction of the outer frame vertical structure will be contrary to the conditions for support removal. In the prior art, in order to avoid the mutual influence between the construction of the outer frame vertical structure and the removal of the supports, the plane layout of the supports is avoided during the support construction phase, thereby avoiding the influence of the unremoved supports on the construction of the outer frame vertical structure. However, in foundation pits with relatively complex surrounding environments, the plane layout of the supports cannot be completely avoided with the outer frame vertical structure to be constructed. At this time, in order to construct the outer frame vertical structure, the supports that are not yet ready for removal need to be removed in advance, which is not conducive to the control of foundation pit deformation and endangers the safety of foundation pit construction. Summary of the Invention

[0003] The purpose of the present invention is to provide a construction method for an outer frame vertical structure and a basement structure that interfere with foundation pit supports, so as to solve the problem that when the outer frame vertical structure and the supports interfere with each other, all the supports and basement structure construction are removed, resulting in large deformation of the foundation pit and endangering the safety of the foundation pit.

[0004] In order to solve the above technical problems, the present invention provides a basement structure construction method of an outer frame vertical structure interfering with foundation pit supports, comprising:

[0005] Construct the basement structure's slab at the bottom of the foundation pit;

[0006] After the basement structure's bottom plate reaches the strength standard, the penultimate and penultimate supports in the foundation pit will be completely removed;

[0007] Plan the hoisting position and underground horizontal transportation route of the first section of the vertical outer frame structure according to the installation position of the first section of the vertical outer frame structure on the bottom plate of the basement structure;

[0008] According to the interference position between the vertical structure of the first section outer frame and each support in the foundation pit, the interference part of the third-to-last support that affects the installation and transportation of the vertical structure of the first section outer frame will be partially removed;

[0009] Arrange the horizontal transport device on the bottom plate according to the planned hoisting position of the vertical structure of the first section outer frame;

[0010] On the ground, the first section of the vertical outer frame structure is hoisted through the gaps between the supports in the foundation pit and onto the horizontal transport device located on the bottom plate according to the planned hoisting position by using the hoisting equipment. The first section of the vertical outer frame structure is then transported to the preliminary installation position of the bottom plate by the horizontal transport device according to the planned underground horizontal transport route.

[0011] Install a precise positioning device on the fourth support from the end just above the installation position of the vertical structure of the first section outer frame, and use the precise positioning device to adjust the vertical structure of the first section outer frame on the horizontal transport device to the precise position of the installation position of the base plate;

[0012] After the first section of the vertical structure of the outer frame at each installation location is completed on the base plate, the precise positioning device is removed and the second to last floor slab of the basement structure is rebuilt;

[0013] After the second-to-last floor slab reaches the strength standard, remove the remaining third-to-last support and rebuild the third-to-last floor slab of the basement structure;

[0014] After the third-to-last floor slab reaches the strength standard, the fourth-to-last support will be completely removed;

[0015] Remove the partial support of the fifth-to-last support and the partial support of the sixth-to-last support that affect the installation of the vertical structure of the outer frame of the last section;

[0016] Use lifting equipment on the ground to hoist each end section of the outer frame vertical structure to the corresponding first section of the outer frame vertical structure;

[0017] After the construction of the vertical structure of the last section of the outer frame is completed, the fourth-to-last floor slab and the top floor slab of the basement structure are rebuilt in sequence.

[0018] Furthermore, the present invention provides a method for constructing a basement structure with a vertical outer frame structure that interferes with foundation pit support.

[0019] The partial support of the third-to-last support that affects the transportation of the vertical structure of the first section of the outer frame will be removed and replaced with a movable support;

[0020] Install a lifting device on the fourth-to-last support above the movable support;

[0021] When the first section of the outer frame vertical structure is transported by the horizontal transport device according to the regular underground transport route and encounters a blockage from the movable support, the movable support is lifted upward by the lifting device so that the movable support and the first section of the outer frame vertical structure on the horizontal transport device are completely cleared, and the first section of the outer frame vertical structure on it is transported by the horizontal transport device according to the predetermined underground horizontal transport route to the initial position of the installation location.

[0022] When the first section of the outer frame vertical structure passes under the lifted movable support, the movable support is lowered by the lifting device and restored to the partially removed part of the third-to-last support.

[0023] Furthermore, in the basement structure construction method of the outer frame vertical structure that interferes with the foundation pit support provided by the present invention, the lifting device is an electric hoist.

[0024] Furthermore, the present invention provides a method for constructing a basement structure of an outer frame vertical structure that interferes with foundation pit supports, wherein the horizontal transportation device includes: a frame, wheels arranged on the frame, a vertical frame arranged on one side of the frame, a clamping hoop arranged above the vertical frame, and a slot arranged on the frame corresponding to the clamping hoop, and the non-last section outer frame vertical structure is clamped by the clamping hoop and clamped in the slot.

[0025] Furthermore, the present invention provides a method for constructing a basement structure with an outer frame vertical structure that interferes with foundation pit supports, wherein the precise positioning device includes a track, a crane arranged on the track, a reel arranged on the crane, a rope wound on the reel, a hook connected to the rope, and a control mechanism arranged on the track, the crane or the support, wherein the control mechanism is used to control the operation of the crane on the track and the lifting and lowering of the hook through the rope.

[0026] In order to solve the above technical problems, the present invention also provides a construction method for an outer frame vertical structure interfering with foundation pit supports, comprising:

[0027] Plan the hoisting position and horizontal transportation route of the non-last section external frame vertical structure based on its installation position on the floor slab;

[0028] According to the interference position between the vertical structure of the first section outer frame and the supports in the foundation pit, the lower two supports of the three supports that affect the installation and transportation of the vertical structure of the first section outer frame will be completely removed, and the interference position of the upper support of the three supports that affect the installation and transportation of the vertical structure of the first section outer frame will be partially removed;

[0029] Arrange a horizontal transport device on the floor slab according to the hoisting position of the non-last section outer frame vertical structure;

[0030] On the ground, the non-last section of the vertical outer frame structure is hoisted through the gaps between the supports in the foundation pit according to the planned hoisting position and placed on the horizontal transport device on the floor slab. The non-last section of the vertical outer frame structure is transported by the horizontal transport device to the preliminary position of the floor slab installation position according to the planned underground horizontal transport route;

[0031] A precise positioning device is installed on the support directly above the installation position of the non-last section outer frame vertical structure, and the non-last section outer frame vertical structure on the horizontal transport device is adjusted to the precise position of the floor slab installation position by the precise positioning device.

[0032] Furthermore, the invention provides a method for constructing a vertical outer frame structure that interferes with foundation pit support.

[0033] Remove the partial support of the upper support among the three supports that affect the transportation of the non-last section outer frame vertical structure and replace it with a movable support;

[0034] Install a lifting device on the upper support above the movable support;

[0035] When the non-last section outer frame vertical structure is transported by the horizontal transport device according to the regular underground transport route and encounters an obstacle caused by the movable support, the movable support is lifted upward by the lifting device so that the movable support and the non-last section outer frame vertical structure are completely cleared, and the non-last section outer frame vertical structure on it is transported by the horizontal transport device according to the predetermined underground horizontal transport route to the preliminary position of the installation location;

[0036] When the non-last section outer frame vertical structure passes under the lifted movable support, the movable support is lowered by the lifting device and restored to the partially removed part of the upper support.

[0037] Furthermore, in the construction method of the vertical structure of the outer frame that interferes with the foundation pit support provided by the present invention, the lifting device is an electric hoist.

[0038] Furthermore, the present invention provides a construction method for a vertical outer frame structure that interferes with foundation pit supports, wherein the horizontal transport device includes: a frame, wheels arranged on the frame, a vertical frame arranged on one side of the frame, a clamping hoop arranged above the vertical frame, and a slot corresponding to the clamping hoop arranged on the frame, and the non-last section vertical outer frame structure is clamped by the clamping hoop and clamped in the slot.

[0039] Furthermore, the present invention provides a construction method for a vertical structure of an outer frame that interferes with a foundation pit support, wherein the precise positioning device includes a track, a crane arranged on the track, a winding drum arranged on the crane, a rope for retracting and winding the winding drum, a hook connected to the rope, and a control mechanism arranged on the track, the crane or the support, wherein the control mechanism is used to control the operation of the crane on the track and the lifting and lowering of the hook through the rope.

[0040] Compared with the prior art, the construction method of the outer frame vertical structure and basement structure that interfere with the foundation pit support provided by the present invention has the following beneficial effects:

[0041] 1. In order to solve the problem of mutual interference between the non-last section outer frame vertical structure and the support in the foundation pit of the basement structure constructed using the core tube technology, the support that affects the construction of the non-last section outer frame vertical structure is partially removed. The foundation pit is supported and force is transmitted through the local support and the supports above it. This solves the problem of excessive deformation of the foundation pit caused by the removal of too many supports at one time, ensures the safety of foundation pit construction, and provides an effective solution for the construction of basement structures of super-high-rise buildings with complex surrounding environments and high protection requirements. It ensures the smooth construction of the basement structure of super-high-rise buildings, reduces the problem of having to set up temporary replacement supports during the construction of traditional non-last section outer frame vertical structures, simplifies the construction process, and is conducive to saving construction costs.

[0042] 2. The vertical structure of each section of the outer frame is hoisted and installed on the ground by lifting equipment, which solves the problem that large mechanical equipment cannot enter the underground space due to the influence of various supports, making it difficult to transport the vertical structure of the outer frame other than the last section.

[0043] 3. The horizontal transport device performs preliminary positioning of the non-last section's vertical outer frame structure in one direction and precise positioning of the non-last section's vertical outer frame structure in another direction. The precise positioning device then performs precise positioning adjustments after the initial positioning of the non-last section's vertical outer frame structure. This allows the non-last section's vertical outer frame structure to be installed at the intended location, ensuring the accuracy of its installation. The horizontal transport device also addresses the difficulty of transporting large steel structures within underground spaces, improving the efficiency of their transportation and installation.

[0044] 4. After the floor slab of the non-last section outer frame vertical structure is rebuilt, the partial upper supports on the three supports that affect the longitudinal span of the non-last section outer frame vertical structure are removed, thereby improving the construction safety of the floor slab of the non-last section outer frame vertical structure of the basement structure.

[0062] The present invention will be described in detail below with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are all in a very simplified form and are not accurately scaled, and are only used to facilitate and clearly illustrate the embodiments of the present invention.

[0063] Example 1

[0064] Please refer to Figures 1 to 7A first embodiment of the present invention provides a method for constructing a basement structure having an outer frame vertical structure interfering with foundation pit supports (i.e., a method for constructing a basement structure having inner and outer frame vertical structures interfering with supports). The basement structure in the first embodiment takes a fourth underground floor as an example, but is not limited to a fourth underground floor. The construction method of the basement structure may include:

[0065] Step 101, please refer to Figure 1 The basement floor slab (i.e., the penultimate floor slab) 401 is constructed at the bottom of the foundation pit 200. A pile-column structure, including upright piles 210 and lattice columns 220, is constructed within the foundation pit 200. A retaining structure 230 is provided within the boundaries of the foundation pit 200, and six supports are provided within the foundation pit 200 via surrounding purlins 240.

[0066] Step 102, please refer to Figures 1 to 2 After the bottom plate 401 of the basement structure reaches the strength standard, the penultimate support 301 and the penultimate support 302 in the foundation pit 200 are completely removed.

[0067] Step 103, please refer to Figures 6 and 7 The hoisting position 500 of the first section of the outer frame vertical structure 501 and the underground horizontal transportation route are planned based on the installation position of the first section of the outer frame vertical structure 501 on the bottom plate 401 of the basement structure. The underground horizontal transportation route is the route from the hoisting position 500 to the installation position of the first section of the outer frame vertical structure 501. The layout position of the first section of the outer frame vertical structure 501 in the figure is the installation position. The hoisting position 500 should be as close to the designed installation position as possible to shorten the distance of the underground horizontal transportation route and improve transportation efficiency and overall construction efficiency.

[0068] Step 104, please refer to Figure 2 、 Figure 7Based on the interference position between the first section's vertical outer frame structure 501 and the corresponding supports within the foundation pit 200 (i.e., the planar layout of the first section's vertical outer frame structure), the interfering portion of the third-to-last support 303 that affects the installation and transportation of the first section's vertical outer frame structure 501 is partially removed (i.e., the partial support 310 that affects the installation of the first section's vertical outer frame structure and the partial support 320 that affects the transportation of the first section's vertical outer frame structure are removed). The partial removal of the third-to-last support 303 and the supports above it control the deformation of the foundation pit 200. In this step 104, there is no need to completely remove the third-to-last support 303. Only the unavoidable support in the third-to-last support 303 (i.e., the influence section of the third-to-last support 303) needs to be removed. The remaining third-to-last support 303 and the supports above it are used to support and transmit force to the foundation pit 200, thereby reducing deformation of the foundation pit and achieving control over the deformation of the foundation pit. This avoids the problem that the foundation pit 200 is easily deformed and endangers the safety of foundation pit construction when the first section of the outer frame vertical structure 501 is constructed under the condition that the first-to-last support 301, the second-to-last support 302, and the third-to-last support 303 are all removed.

[0069] Step 105, please refer to Figure 2 、 Figure 7 , a horizontal transport device 600 is arranged on the bottom plate 401 according to the hoisting position 500 planned by the first section outer frame vertical structure 501. The horizontal transport device 600 can be arranged vertically corresponding to the hoisting position 500, or can be staggered.

[0070] Step 106, please refer to Figure 2 、 Figure 7 , on the ground, through the lifting equipment such as cranes and hoists (not shown), the first section of the outer frame vertical structure 501 is lifted through the gaps between the supports in the foundation pit 200 to the horizontal transportation device 600 located on the bottom plate 401 according to the planned lifting position 500, and the first section of the outer frame vertical structure 501 on it is transported to the preliminary (approximate) position of the installation position of the bottom plate 401 according to the planned underground horizontal transportation route by the horizontal transportation device 600. The horizontal transportation device 600 can roughly position the first section of the outer frame vertical structure 501 on it in one direction and accurately position it in another direction. The lifting of the first section of the outer frame vertical structure 501 on the ground facilitates the vertical transportation of non-last section outer frame vertical structures such as the first section of the outer frame vertical structure 501 to the bottom plate 401, and solves the problem that the underground space is affected by the supports, resulting in the inability of large mechanical equipment to enter and the difficulty in transporting non-last section outer frame vertical structures.

[0071] Step 107, please refer to Figure 2 、 Figure 10, install the precise positioning device 700 on the fourth-to-last support 304 just above the installation position of the first section outer frame vertical structure 501, and adjust the first section outer frame vertical structure 501 on the horizontal transport device 600 to the precise position of the installation position of the base plate 401 through the precise positioning device 700. Then withdraw the horizontal transport device 600. At this time, the precise positioning device 700 needs to be connected to the first section outer frame vertical structure 501 on the horizontal transport device 600 at the approximate position, and then adjust its position. The precise positioning device 700 can precisely position the first section outer frame vertical structure 501 in another direction, and precise positioning in two directions can be achieved through the horizontal transport device 600 and the precise positioning device 700. When there is no support at the installation position of the precise positioning device 700, it can be installed through a temporary horizontal steel structure.

[0072] Step 108, please refer to Figure 2 After the first section of the outer frame vertical structure 501 is completed on the bottom plate 401 at each installation location, the precise positioning device 700 is removed and the second-to-last floor slab 402 (i.e., the fourth floor slab) and the corresponding exterior wall of the basement structure are rebuilt. After the construction of the first section of the outer frame vertical structure 501 is completed, a certain number of temporary supports can be installed between the first section of the outer frame vertical structure 501 and the supports that have not yet been removed to improve the integrity of the foundation pit support structure system and ensure the safety of foundation pit construction.

[0073] Step 109, please refer to Figures 2 to 3 After the second-to-last floor slab 402 reaches the strength standard, the remaining third-to-last support 303 is removed, and the third-to-last floor slab 403 (i.e., the third-to-last floor slab) and its outer wall of the basement structure are rebuilt.

[0074] Step 110, please refer to Figures 3 and 4 After the third-to-last floor slab 403 reaches the strength standard, the fourth-to-last support 304 will be completely removed.

[0075] Step 111, please refer to Figure 4 , remove the partial support of the fifth-to-last support 302 and the partial support of the sixth-to-last support 301 that affect the installation of the vertical structure of the last section outer frame.

[0076] Step 112, please refer to Figure 4 , each end section outer frame vertical structure 502 is hoisted onto the corresponding first section outer frame vertical structure 501 on the ground using hoisting equipment.

[0077] Step 113, please refer to Figure 5After the construction of the final section of the outer frame vertical structure 502 is completed, the fourth-to-last floor slab 404 (i.e., the second-to-last floor slab) and the top floor slab (i.e., the fifth-to-last floor slab 405) of the basement structure are sequentially rebuilt. The precise positioning device 700 can also be removed before rebuilding the fourth-to-last floor slab 404.

[0078] The sequence of the above steps can be adjusted as needed.

[0079] Please refer to Figure 8 In order to ensure the safety of the foundation pit 200 and reduce the impact on transportation caused by the partial removal of the third-to-last support 303, which leads to discontinuity after the third-to-last support 303 is disconnected and affects the force transmission effect on the foundation pit 200, the first embodiment of the present invention provides a basement structure construction method with an outer frame vertical structure interfering with the foundation pit support, which may also include:

[0080] In step 121, the third-to-last support 303, which affects the transport of the first section of the vertical outer frame structure 501, is partially removed and replaced with movable supports 330. Based on the planned transport route, the number of movable supports should be minimized. Specifically, for unavoidable supports along the underground horizontal transport route, removable movable supports 330 are used to replace them. This reduces the problem of discontinuity in the third-to-last support 303 and the resulting impact on force transmission to the foundation pit.

[0081] Step 122: Install a lifting device 800 on the fourth-to-last support 304 above the movable support 330. The lifting device 800 may be an electric hoist.

[0082] In step 123, when the first section of the vertical outer frame structure 501 is transported by the horizontal transport device 600 according to the regular underground transport route and encounters an obstruction from the movable support 330, the movable support 330 is lifted upward by the lifting device 800 so that the movable support 330 and the first section of the vertical outer frame structure 501 on the horizontal transport device 600 are completely clear of each other, and the first section of the vertical outer frame structure 501 on the horizontal transport device 600 is transported to the preliminary (approximate) position of the installation location according to the predetermined underground horizontal transport route by the horizontal transport device 600. That is, by lifting the movable support 330 upward, the underground horizontal transport route is unblocked, thereby ensuring that the first section of the vertical outer frame structure 501 can be transported smoothly.

[0083] In step 124, after the first section of the outer frame vertical structure 501 passes under the lifted movable support 330, the lifting device 800 lowers the movable support 330 and restores it to the partially removed portion of the third-to-last support 303. Specifically, by lowering the movable support 330, the third-to-last support 303 that affects transportation is partially removed and then replaced with the movable support. This completes the support removed during the transportation section of the third-to-last support 303, reduces unnecessary removal of the third-to-last support 303, and transmits force to the foundation pit through the partial third-to-last support 303, thereby reducing deformation and ensuring pit safety.

[0084] The movable support 330 is designed to keep the third-to-last support 303, which affects the transport section, connected and unbroken when not in transport, effectively controlling pit deformation. To meet the rigidity requirements for force transmission, the movable support 330 can be made of steel. To facilitate lifting operations, the movable support 330 can be detachably connected to the transport section of the third-to-last support 303.

[0085] Please refer to Figure 2 and Figure 9 In order to ensure the transportation safety of non-last-section vertical structures such as the first-section vertical structure of the outer frame 501, an embodiment of the present invention provides a method for constructing a basement structure of a vertical structure of the outer frame that interferes with the foundation pit support. The horizontal transportation device 600 includes: a frame 610, wheels 620 arranged on the frame 610, a stand 630 arranged on one side of the frame 610, a clamp 640 arranged above the stand 630, and a slot 650 arranged on the frame 610 corresponding to the clamp 640. The first-section vertical structure of the outer frame 501 is clamped by the clamp 640 and clamped in the slot 650. The clamp 650 device can prevent the non-last-section vertical structure of the outer frame, such as the first-section vertical structure of the outer frame 501, from slipping relative to the horizontal transportation device 600 during horizontal transportation, and the clamp 640 can prevent the non-last-section vertical structure of the outer frame from overturning during transportation. The horizontal transportation device 600 can also be used for the horizontal transportation of basement steel structures to improve the transportation efficiency of basement steel structures. In addition, the horizontal transport device 600 is provided with a stand 630 on one side of the vehicle frame 610, the purpose of which is to facilitate the taking and placing of the non-last section outer frame vertical structure.

[0086] Please refer to Figure 2 and Figure 9In order to accurately position the first section, middle section and other non-last section outer frame vertical structures, the embodiment of the present invention provides a basement structure construction method for the outer frame vertical structure that interferes with the foundation pit support. The precise positioning device 700 includes a track 710, a crane 720 arranged on the track 710, a winding drum 730 arranged on the crane 720, a rope 740 wound on the winding drum 730, a hook 750 connected to the rope 740, and a control mechanism (not shown) arranged on the track 710, the crane 720 or the support. The control mechanism is used to control the operation of the crane 720 on the track 710 and the lifting and lowering of the hook 750 through the rope 740. Figure 9 The example in the figure shows the case where the track 710 is set on the upper chord surface of the fourth-to-last support 304, which can be anchored or connected by a clamp. At this time, the crane 720 and the cable reel 730 thereon are set on the upper chord surface of the fourth-to-last support 304, which can improve the stability and bearing capacity of the precise positioning device 700 and prevent the precise positioning device 700 from falling due to unreliable installation on the fourth-to-last support 304 or failure to meet the bearing capacity requirements. Before precise positioning and adjustment, it is necessary to connect the hook to the vertical structure 501 of the first section outer frame through a rope. The control mechanism is a well-known technology.

[0087] Example 2

[0088] In order to expand the application scope of non-last section vertical outer frame structures, a second embodiment of the present invention provides a construction method for a vertical outer frame structure interfering with foundation pit supports, which may include:

[0089] Step 131: Plan the hoisting position 500 and horizontal transportation route of the non-last vertical frame structure based on its installation position on the floor slab. The non-last vertical frame structure includes at least the first vertical frame structure 501, and may also include the first vertical frame structure 501 and the intermediate vertical frame structures above it.

[0090] In step 132, based on the interference between the first section's vertical outer frame structure 501 and the various supports within the foundation pit 200, the lower two of the three supports that affect the installation and transportation of the first section's vertical outer frame structure 501 are completely removed, and the upper support of the three supports that affect the installation and transportation of the first section's vertical outer frame structure 501 is partially removed. The partially removed upper support and the supports above it are used to control deformation of the foundation pit 200, thereby ensuring safety in foundation pit construction.

[0091] Step 133 : Arrange the horizontal transport device 600 on the floor slab according to the hoisting position 500 of the non-last section outer frame vertical structure.

[0092] Step 134, on the ground, use lifting equipment to lift the non-last section outer frame vertical structure through the gaps between the supports in the foundation pit 200 and onto the horizontal transportation device 600 located on the floor slab according to the planned lifting position 500, and use the horizontal transportation device 600 to transport the non-last section outer frame vertical structure on it to the preliminary (approximate) position of the installation position of the floor slab according to the planned underground horizontal transportation route.

[0093] In step 135, a precise positioning device 700 is installed on the support directly above the installation location of the non-last section vertical external frame structure. The precise positioning device 700 is used to adjust the non-last section vertical external frame structure on the horizontal transport device 600 to the precise installation location of the floor slab on the corresponding floor. The precise positioning device 700 can be installed after the local supports 310 that affect the installation of the first section, middle section, and other non-last section vertical external frame structures are removed, without having to wait until the non-last section vertical external frame structure is transported to the preliminary (approximate) installation location of the floor slab before starting installation.

[0094] In order to ensure the safety of the foundation pit 200 and reduce the impact on the force transmission effect of the foundation pit 200 caused by the partial removal of the support that affects transportation, resulting in discontinuity after the support is broken, the construction method of the vertical outer frame structure that interferes with the foundation pit support provided in the second embodiment of the present invention may further include:

[0095] In step 141 , a partial support of the upper support among the three supports that affect the transportation of the non-last section outer frame vertical structure is removed and replaced with a movable support 330 .

[0096] Step 142 , installing a lifting device 800 on the upper support above the movable support 330 .

[0097] In step 143, when the non-last vertical outer frame structure is transported by the horizontal transport device 600 along the regular underground transport route and encounters an obstruction from the movable support 330, the movable support 330 is lifted upward by the lifting device 800 so that the movable support 330 and the non-last vertical outer frame structure are completely clear of each other. The non-last vertical outer frame structure is then transported by the horizontal transport device 600 along the predetermined underground horizontal transport route to the preliminary (approximate) position of the installation location. After the obstruction is completely avoided, the underground horizontal transport route is ensured to be unobstructed.

[0098] Step 144 , when the non-last section outer frame vertical structure passes under the lifted movable support 330 , the lifting device 800 is used to lower the movable support 330 and restore it to the partially removed portion of the upper support.

[0099] The construction method of the vertical outer frame structure interfering with the foundation pit support provided in the second embodiment of the present invention is not limited to the construction of a four-story basement structure and is universal.
