Description

Technical Field

[0001] The present invention relates to the technical field of dock construction, and in particular to a movable inverted hanging formwork support system and a breast wall construction method. Background Art

[0002] Existing docks typically use steel pipe piles to enclose the main support structure of the dock, and construct a breast wall facing the waterside of the dock on the steel pipe piles to mitigate the impact of wind and waves on the main support structure, thereby extending the service life of the dock. However, the waterside of the breast wall protrudes outward from the steel sheet piles or steel pipe piles, forming a cantilever structure with no support at the bottom. Therefore, its construction involves overwater cantilevering operations, which are extremely tedious and complex. It is often necessary to first use cranes and boats to build a temporary support structure on the waterside of the breast wall, then assemble the breast wall formwork and pour concrete on site, and finally dismantle the temporary support structure. However, this construction method has the following problems: (1) The breast wall needs to be set up around the dock, so it is often very long. If the corresponding formwork needs to be assembled and dismantled on site when constructing each section of the breast wall, a lot of manpower and material resources will be required to carry out a lot of repetitive work, which will lead to low construction efficiency of the breast wall, increased construction costs and construction period.

[0003] (2) The breast wall needs to directly resist the impact of wind and waves, so the construction quality of its waterside is crucial; however, due to the limitations of construction site conditions, such as lifting equipment, personnel experience level, and the setting of temporary support structures, on-site assembly of formwork can easily lead to errors in the positioning of the formwork, causing the cross-sectional shape of the breast wall to deviate from the designed shape, thereby reducing the service life of the breast wall.

[0004] (2) As it involves overwater / underwater construction, the construction method of on-site assembled formwork also has the risk that the construction period is easily affected by climate and hydrological conditions, and is prone to overwater / underwater construction accidents, which will further increase the construction period and construction risks of the breast wall.

[0005] Based on the above problems, it is urgent to develop a new breast wall formwork system and corresponding construction method. Summary of the Invention

[0006] The purpose of the present invention is to overcome the technical problems of the prior art method of constructing breast walls using on-site assembled formwork, which not only has low construction efficiency, high construction costs and a long construction period, but also easily causes the shape of the breast wall to deviate from the design requirements, and to provide a movable inverted hanging formwork support system and a breast wall construction method.

[0007] In a first aspect, the present invention provides a movable inverted formwork support system, comprising a crossbeam, the length of which is arranged along a first horizontal direction; a walking mechanism, a backwater side formwork and a water-facing side formwork are sequentially connected at intervals along the first direction at the bottom of the crossbeam; the walking direction of the walking mechanism is arranged along a second horizontal direction, the second direction being perpendicular to the first direction; the normal of the backwater side formwork is parallel to the first direction, the top of the backwater side formwork is connected to the crossbeam, and the bottom of the backwater side formwork is also movably connected to a backwater bottom formwork on the side facing the water side formwork; the backwater bottom formwork and the backwater side formwork are arranged in a horizontal direction. The normals are perpendicular to each other, and the backwater bottom mold can move relative to the backwater side mold along the first direction; the normal of the waterfront side mold is perpendicular to the second direction, the top of the waterfront side mold is swingably connected to the crossbeam, the axis of the swing connection is parallel to the second direction, and the bottom of the waterfront side mold is also connected to the side of the backwater side mold facing the backwater side mold, and the normals of the waterfront bottom mold and the waterfront side mold are perpendicular to each other; an end mold plate is also connected between at least one end of the backwater side mold along the second direction and the corresponding end of the waterfront side mold, the normal of the end mold plate is parallel to the second direction, and the end mold plate is detachably connected to the waterfront side mold.

[0008] When using this solution, the movable inverted formwork support system can be first set up at the water's edge, and the posture is: the walking mechanism is located on land, and the backwater side formwork and the water-facing side formwork are respectively located on both sides of the existing steel pipe piles along the first direction; then the position of the backwater bottom formwork is adjusted along the first direction, and the angle of the water-facing side formwork is adjusted around the second direction, so that the backwater bottom formwork and the water-facing bottom formwork are close to each other until they clamp the steel pipe piles, and the position locking relative to the steel pipe piles of this solution can be completed. At this time, the end formwork is connected to the ends of the water-facing side formwork and the backwater side formwork, and an upper opening area can be enclosed by the backwater side formwork, the backwater bottom formwork, the water-facing side formwork, the water-facing bottom formwork and the end formwork, and concrete can be poured into this area to form a breast wall of corresponding shape.

[0009] When the breast wall construction of a workstation is completed, the connection between the end formwork and the water-facing side formwork is released, and the position of the backwater bottom formwork and the angle of the water-facing side formwork are adjusted again, so that the backwater bottom formwork and the water-facing bottom formwork can be loosened from the steel pipe piles, thereby releasing the position lock of this scheme relative to the steel pipe piles, so that this scheme can be directly moved to the next casting station through the walking structure, and the breast wall of the corresponding casting station can be cast in the same way.

[0010] As can be seen from the above, this solution can achieve position locking relative to the steel pipe piles through the backwater side formwork, backwater bottom formwork, water-facing side formwork and water-facing bottom formwork that can be moved as a whole to the beam through a walking mechanism, and through the movable backwater bottom formwork and water-facing side formwork. Compared with the existing technology that requires repeated assembly and dismantling of breast wall formwork, this solution can save a lot of repetitive labor, thereby improving construction efficiency, reducing construction costs and construction period.

[0011] In this scheme, the shape of the breast wall is determined by the geometric shapes and relative positional relationships of the backwater side formwork, backwater bottom formwork, waterfront side formwork, waterfront bottom formwork and end formwork. Its accuracy is mainly controlled by the factory's machining level, and has nothing to do with factors such as lifting equipment, personnel experience level and the setting of temporary support structures. This is conducive to improving the construction quality of the breast wall, ensuring that the cross-sectional shape of the breast wall meets the design requirements, and thus ensuring the service life of the breast wall.

[0012] At the same time, the main components of this solution are all connected to the beam, and the beam is set on land through a walking mechanism. Therefore, this solution can also avoid most of the above-water / underwater construction, which is conducive to further reducing the construction cost, construction period and construction risk of this solution.

[0013] Preferably, the bottom of the crossbeam is also movably connected to a support leg, which is located between the walking mechanism and the backwater side mold and the waterside mold along the first direction, and the support leg can move relative to the crossbeam along the third direction.

[0014] Since the back-to-water side formwork, back-to-water bottom formwork, water-facing side formwork and water-facing bottom formwork are all set close to the water end of the beam, when pouring concrete, the weight of the concrete will produce a tipping moment toward the water's edge on this scheme, which may cause the entire scheme to flip into the water.

[0015] Therefore, this solution sets support legs at the bottom of the beam. The support legs are located between the backwater side formwork and the waterside formwork, that is, above the steel pipe piles. When the support legs move downward along the third direction, the bottom of the support legs can support the top of the existing steel pipe piles, thereby generating an upward support reaction force at the water end of the beam, thereby offsetting part or all of the tipping moment and reducing the risk of rollover. When it is necessary to move this solution, the support legs are moved upward along the third direction to separate the support legs and the steel pipe piles, thereby preventing the steel pipe piles from hindering the movement of this solution. Compared with fixing the beam with ground anchors, the method of setting support legs can also reduce the damage caused to the dock ground by breast wall construction.

[0016] Preferably, a reaction bracket is connected to the top of the beam, and the reaction bracket extends along the third direction away from the beam; a first telescopic rod is provided in the reaction bracket, the top end of the first telescopic rod is connected to the reaction bracket, and the bottom end of the first telescopic rod is connected to the longitudinal beam; the length of the longitudinal beam is set along the second direction; the support legs are located below the longitudinal beam, and at least two support legs are spaced apart along the second direction.

[0017] This solution arranges at least two supporting legs at intervals along the second direction, so that this solution can be more firmly supported on the existing steel pipe piles, thereby further reducing the probability of this solution rolling over; at the same time, this solution also synchronously controls the lifting and lowering of at least two supporting legs through the first telescopic rod and the longitudinal beam at its end, which can not only improve the utilization efficiency of the first telescopic rod, but also reduce the complexity of the support leg lifting control system; and compared with directly arranging the first telescopic rod at the bottom of the beam, this solution arranges the reaction support and the first telescopic rod at the top of the beam, which can avoid the problem that the length of the first telescopic rod causes the height of the beam to be too high, thereby causing the stability of this solution to decrease.

[0018] Preferably, a suspension rod is detachably connected between the backwater bottom form and the cross beam, and / or a suspension rod is detachably connected between the water-facing bottom form and the cross beam; a protective tube is provided on the outside of the suspension rod, and the inner wall of the protective tube is gap-fitted with the outer wall of the suspension rod.

[0019] When pouring concrete, the weight of the concrete will directly act on the upper surface of the backwater bottom formwork and the water-facing bottom formwork. If the strength of the backwater bottom formwork and the water-facing bottom formwork is insufficient, it is easy for them to deflect and deform or even be damaged, thereby causing the cross-sectional shape of the breast wall to deviate from the design requirements or even fail in pouring. Therefore, this solution sets a hanger between the backwater bottom formwork and the crossbeam, and / or sets a hanger between the water-facing bottom formwork and the crossbeam, which can transfer the load on the backwater bottom formwork and the water-facing bottom formwork to the crossbeam, thereby improving the force on the backwater bottom formwork and the water-facing bottom formwork, and avoiding the situation where the backwater bottom formwork and the water-facing bottom formwork occur deflecting and deforming or even being damaged.

[0020] At the same time, since the outer sleeve of the hanger is provided with a protective tube, when the concrete solidifies, only the protective tube will be fixed inside the concrete, and the hanger can still be disassembled, so that when the solution needs to be moved, the hanger will not hinder the movement of the solution.

[0021] Preferably, a counterweight block is further provided on the crossbeam, and the counterweight block is located along the first direction on the side of the back-to-water side mold away from the water-facing side mold.

[0022] When pouring concrete, the weight of the concrete will generate a tipping moment towards the water's edge on this scheme, which may cause the scheme to overturn into the water as a whole; therefore, this scheme sets a counterweight block on the backwater end of the beam, which can generate downward pressure at the backwater end of the beam, thereby offsetting part or all of the tipping moment and reducing the risk of rollover; and compared with common ground anchors, the method of setting a counterweight block can also reduce the damage caused by breast wall construction to the dock ground.

[0023] Preferably, it also includes an extension arm and a second telescopic rod; one end of the extension arm is connected to the top of the water-facing side mold, and the other end of the extension arm extends along the third direction to the top of the beam; one end of the second telescopic rod is hinged to the beam, and the other end of the second telescopic rod is hinged to the end of the extension arm away from the water-facing side mold, and the axes of the hinge are parallel to the second direction.

[0024] This solution can control the swing angle of the water-facing side formwork by extending and retracting the second telescopic rod; and compared to directly connecting the second telescopic rod to the water-facing side formwork, this solution provides an extension arm at the top of the water-facing side formwork, which can enable the corresponding actuating mechanism, that is, the second telescopic rod to be located above the water-facing side formwork, thereby avoiding the mutual influence between the actuation of the second telescopic rod and the pouring of concrete, and also avoiding the problem that the size of the second telescopic rod causes the height of the beam to be too high, thereby reducing the stability of this solution.

[0025] Preferably, the walking mechanism includes walking wheels and walking tracks, the walking wheels are rotatably connected to the crossbeam, and the axis of the rotatable connection is parallel to the first direction; the length of the walking track is set along the second direction, and the walking wheels can roll on the walking track.

[0026] This solution provides one of the specific walking mechanisms.

[0027] Preferably, the number of the cross beams is at least two, and the cross beams are distributed at intervals along the second direction.

[0028] In a second aspect, the present invention provides a breast wall construction method, which is applied to a movable inverted formwork support system of the present invention, comprising the following steps: S1. Install the movable inverted formwork support system at the water's edge, with the traveling mechanism located on land. The backwater side formwork and the waterfront side formwork are located on either side of the existing steel pipe piles along a first direction. Adjust the position of the backwater bottom formwork along the first direction and adjust the angle of the waterfront side formwork along a second direction so that the backwater bottom formwork and the waterfront bottom formwork approach each other until they clamp the steel pipe piles. Connect the ends of the end formwork to the backwater side formwork and the waterfront side formwork, respectively. S2. Pour concrete in the area enclosed by the backwater side formwork, backwater bottom formwork, waterfront side formwork, waterfront bottom formwork, and end formwork to complete the construction of the corresponding breast wall segment; S3, releasing the connection between the end formwork and the waterside formwork; adjusting the position of the backwater bottom formwork along the first direction and adjusting the angle of the waterside side formwork around the second direction, so that the backwater bottom formwork and the waterside bottom formwork are separated from each other until the steel pipe pile is loosened; S4. Make the traveling mechanism travel in the second direction until the movable inverted formwork support system moves to the next pouring station.

[0029] Preferably, when the movable inverted formwork support system further includes support legs, step S1 further includes the following steps: Adjust the position of the support legs along the third direction until the support legs are supported on the top of the steel pipe piles; Step S3 also includes the following steps: Adjust the position of the support leg along the third direction until the support leg is separated from the top of the steel pipe pile.

[0030] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a movable inverted formwork support system, which can move the backwater side formwork, backwater bottom formwork, water-facing side formwork and water-facing bottom formwork connected to the crossbeam as a whole through a walking mechanism, and switch the position of this scheme relative to the steel pipe pile through the movable backwater bottom formwork and water-facing side formwork, and then use it to pour concrete for the breast wall; compared with the existing technology that requires repeated assembly and dismantling of the breast wall formwork, this scheme can save a lot of repetitive labor and water / underwater construction, thereby improving construction efficiency, reducing construction costs and construction period, and at the same time it is also beneficial to improve the construction quality and service life of the breast wall.

[0031] 2. The present invention provides a breast wall construction method. By using the movable inverted formwork support system of the present invention to construct the breast wall, the construction efficiency of the breast wall can be improved, the construction cost and construction period of the breast wall can be reduced, and better construction quality can be obtained.

DETAILED DESCRIPTION

[0033] The present invention will be further described in detail below with reference to specific embodiments. However, this should not be construed as limiting the scope of the present invention to the following embodiments, as all technologies implemented based on the present invention fall within the scope of the present invention.

[0034] Unless otherwise specified, in the description of the specific embodiments of the present invention, the terms indicating the orientation or positional relationship, such as "upper", "lower", "left", "right", "center", "inside", and "outside", are based on the expressions of the orientation or positional relationship shown in the accompanying drawings, or are the orientation or positional relationship in which the invented product / device / apparatus is placed when it is conventionally used. These terms of orientation or positional relationship are merely for the purpose of facilitating the description of the scheme of the present invention or simplifying the description of the specific embodiments to facilitate the rapid understanding of the scheme by technicians, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship, and therefore should not be understood as limiting the present invention.

[0035] In addition, if the terms "horizontal", "vertical", "overhanging", "parallel" and the like appear, it does not mean that the corresponding devices / components / elements are required to be absolutely horizontal or vertical or overhanging or parallel, but may be slightly tilted or have deviations. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but may be slightly tilted. Alternatively, it can be simply understood that the corresponding devices / components / elements are set in directions such as "horizontal", "vertical", "overhanging", and "parallel", and can have an error / deviation of ±10% relative to the corresponding direction setting, more preferably an error / deviation within ±8%, more preferably an error / deviation within ±6%, more preferably an error / deviation within ±5%, and more preferably an error / deviation within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its role in the solution of the present invention.

[0036] In addition, the expressions “first”, “second”, “third”, etc. in the terms are merely used to distinguish the description of the same or similar components, and should not be understood as emphasizing or implying the relative importance of specific components.

[0037] In addition, in the description of the embodiments of the present invention, "several," "plurality," and "a number" represent at least two. It can also be any number such as two, three, four, five, six, seven, eight, nine, or even more than nine.

[0038] Furthermore, in the description of the technical solution of the present invention, unless otherwise expressly specified, defined, or limited, the terms "disposed," "installed," "connected," "connected," "provided with," "laid," and "arranged" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections. They may be welded, riveted, bolted, threaded, or other commonly used connection methods in the art. Such connections may be mechanical, electrical, or communicative; they may be direct, indirect via an intermediate medium, or internally connected between two components.

[0039] Example 1 like Figures 1 to 7 As shown, a movable inverted hanging formwork support system includes a crossbeam 1, a walking mechanism, a backwater side formwork 31, a backwater bottom formwork 32, a water-facing side formwork 41, a water-facing bottom formwork 42 and an end formwork 5; Figures 2 to 7 The directions are also marked using a rectangular coordinate system, where the direction indicated by the arrow X is the first direction, i.e., the length direction of the breast wall 8; the direction indicated by the arrow Y is the second direction; and the direction indicated by the arrow Z is the third direction, i.e., the height direction. It should be noted that, since the support legs 61 and the end template 5 will block each other, Figures 1 to 3 The support legs 61 are hidden. Figures 4 to 7 The end template 5 is hidden in the figure so that the support legs 61 and the end template 5 can be identified respectively in different drawings.

[0040] The length of the beam 1 is arranged along a first horizontal direction; the traveling mechanism, the backwater side mold 31 and the waterfront side mold 41 are sequentially connected to the bottom of the beam 1 along the first direction.

[0041] The walking direction of the walking mechanism is set along a horizontal second direction, and the second direction is perpendicular to the first direction; the walking mechanism can adopt existing technology, including but not limited to a wheeled walking mechanism, a crawler walking mechanism or a foot-walking mechanism.

[0042] The normal direction of the backwater side mold 31 is parallel to the first direction, and the top of the backwater side mold 31 is connected to the crossbeam 1. The specific connection method depends on the available space between the crossbeam 1 and the backwater side mold 31. For example, when there is no structural obstruction between the crossbeam 1 and the backwater side mold 31, the top of the backwater side mold 31 can be directly connected to the bottom of the crossbeam 1; when there is a structural obstruction between the crossbeam 1 and the backwater side mold 31 or the installation space is narrow, Figure 5 As shown, the backwater side form 31 is suspended below the beam 1 using a suspension rod 12 .

[0043] The backwater bottom mold 32 is connected to the side of the bottom of the backwater side mold 31 facing the water side mold 41, and the normals of the backwater bottom mold 32 and the backwater side mold 31 are perpendicular to each other; the side of the backwater bottom mold 32 away from the backwater side mold 31 along the first direction is used to abut against the steel pipe pile 9, and its shape matches the shape of the backwater side of the steel pipe pile 9.

[0044] The connection between the backwater bottom mold 32 and the backwater side mold 31 is a movable connection, so that the backwater bottom mold 32 can move relative to the backwater side mold 31 along the first direction. The specific method of the movable connection can be various existing mechanisms that at least include the freedom of movement along the first direction, for example: a slide groove, a slide rail slider mechanism or a screw nut mechanism with a length along the first direction is set at the bottom of the backwater side mold 31, and then the backwater bottom mold 32 is placed in the slide groove and connected to the slider or nut; or the backwater bottom mold 32 and the backwater side mold 31 are directly connected through a telescopic rod with a length along the first direction.

[0045] It should be noted that some movable connection methods may cause a gap to form between the backwater bottom formwork 32 and the backwater side formwork 31 when the backwater bottom formwork 32 moves, thereby causing concrete leakage; in this case, a strapping board can be set above the backwater bottom formwork 32, and the length of the strapping board along the first direction is greater than the stroke of the backwater bottom formwork 32, so that even if the backwater bottom formwork 32 moves away from the backwater side formwork 31 along the first direction, the strapping board can cover the gap between the backwater bottom formwork 32 and the backwater side formwork 31 to prevent concrete leakage.

[0046] The normal of the water-facing side formwork 41 is perpendicular to the second direction, the top of the water-facing side formwork 41 is swingably connected to the crossbeam 1, and the axis of the swinging connection is parallel to the second direction; the water-facing bottom formwork 42 is connected to the side of the bottom of the water-facing side formwork 41 facing the back-water side formwork 31, and the normals of the water-facing bottom formwork 42 and the water-facing side formwork 41 are perpendicular to each other; the side of the water-facing bottom formwork 42 away from the water-facing side formwork 41 along the first direction is used to abut against the steel pipe pile 9, and its shape matches the shape of the water-facing side of the steel pipe pile 9.

[0047] It should be noted that, since the water-facing side of the breast wall 8 may have various shapes, such as a plane or a stepped shape, the shape of the water-facing side form 41 is not limited to a standard plane shape, but needs to match the shape of the water-facing side of the breast wall 8; for example Figure 4 The waterside formwork 41 is a planar structure corresponding to the breast wall 8 having a roughly rectangular cross section; Figures 5 to 7 The waterside formwork 41 is stepped to correspond to the breast wall 8 which has a roughly inverted L-shaped cross section.

[0048] An end formwork 5 is also connected between at least one end of the backwater side formwork 31 along the second direction and the corresponding end of the waterside formwork 41. The normal of the end formwork 5 is parallel to the second direction, and one end along the first direction is connected to the backwater side formwork 31, and the other end is detachably connected to the waterside formwork 41, such as a bolt connection or a snap connection; the number of end formworks 5 depends on the actual casting situation; for example, when constructing the first section of the breast wall 8, end formworks 5 can be respectively set at both ends of the backwater side formwork 31 and the waterside side formwork 41 along the second direction to enclose a casting area with an upper opening; but when the construction is subsequent and adjacent to the breast wall 8, since the side wall of the constructed breast wall 8 along the second direction can play the role of the end formwork 5, at this time, the end formwork 5 can be set only at the ends of the backwater side formwork 31 and the waterside side formwork 41 along the second direction away from the constructed breast wall 8.

[0049] In an optional embodiment, if Figures 4 to 7 As shown, the bottom of the beam 1 is also movably connected to a support leg 61, and the support leg 61 can move relative to the beam 1 along the third direction. The specific method of the movable connection can be various existing mechanisms that at least include the freedom of movement along the third direction, for example: a slide groove, a slide rail slider mechanism or a screw nut mechanism with a length along the third direction is set on the beam 1, and then the support leg 61 is sleeved on the slide groove and connected to the slider or nut; or the backwater bottom mold 32 and the backwater side mold 31 are directly connected through a telescopic rod with a length along the third direction; the support leg 61 is located between the walking mechanism and the backwater side mold 31 and the water-facing side mold 41 along the first direction, so that when the support leg 61 moves downward along the third direction, the support leg 61 can be as shown Figure 5 It is shown supported on the top of the existing steel pipe pile 9.

[0050] In an optional embodiment, a reaction support 62 is connected to the top of the beam 1, and the reaction support 62 extends along the third direction away from the beam 1; a first telescopic rod 101 is provided in the reaction support 62, the top of the first telescopic rod 101 is connected to the reaction support 62, and the bottom end of the first telescopic rod 101 is connected to the longitudinal beam 63; the length of the longitudinal beam 63 is set along the second direction; the support leg 61 is located below the longitudinal beam 63, and at least two support legs 61 are spaced apart along the second direction, so that when the first telescopic rod 101 extends and drives the longitudinal beam 63 to press down, the longitudinal beam 63 can press on the top of the support leg 61, and then drive the support leg 61 to continue to move downward and press on the top of the existing steel pipe pile 9, forming a load transfer path of beam 1-reaction support 62-first telescopic rod 101-support leg 61-steel pipe pile 9.

[0051] In the above embodiment, the first telescopic rod 101, and the subsequent second telescopic rod 102 and third telescopic rod 103 may all adopt existing technologies, including but not limited to hydraulic cylinders or electric telescopic rods.

[0052] In the above embodiment, the connection method between the longitudinal beam 63 and the support leg 61 includes but is not limited to a rigid connection and a flexible connection, for example, directly fixing the top of the support leg 61 to the bottom of the longitudinal beam 63, or hanging the support leg 61 to the bottom of the longitudinal beam 63 by a sling or an iron chain. As long as the longitudinal beam 63 can drive the support leg 61 to move downward until it is pressed against the top of the steel pipe pile 9 when it moves downward, and can drive the support leg 61 to move upward until it is separated from the top of the steel pipe pile 9 when the longitudinal beam 63 moves upward, it will be sufficient.

[0053] In the above embodiment, when multiple support legs 61 are spaced apart along the second direction, some of the support legs 61 may be located within the concrete pouring area. For these support legs 61, protective sleeves may be installed on the exterior of the support legs 61. The inner wall of the protective sleeves is loosely fitted with the outer wall of the support legs 61. Thus, after the concrete solidifies, only the protective sleeves are fixed within the concrete, while the support legs 61 can still move freely and be removed from the concrete structure, thereby preventing them from obstructing the movement of the movable inverted formwork support system. The specific structural form of the protective sleeves includes, but is not limited to, plastic tubes or steel tubes.

[0054] In an optional embodiment, a suspension rod 12 is detachably connected between the backwater bottom form 32 and the crossbeam 1, and / or a suspension rod 12 is detachably connected between the frontwater bottom form 42 and the crossbeam 1; for example Figure 6 The figure shows a situation where a suspender 12 is additionally connected between the backwater bottom formwork 32 and the crossbeam 1.
