Description

Technical Field

[0001] This invention belongs to the field of retaining wall construction technology, and particularly relates to a movable retaining wall formwork and a retaining wall construction process. Background Technology

[0002] Retaining walls, as crucial structural facilities in civil engineering, primarily function to support soil or rock, effectively resisting external loads such as gravity, water pressure, and wind pressure, preventing them from sliding or collapsing. Retaining walls are typically constructed using formwork and concrete pouring. Given that retaining walls often extend over considerable distances, construction is frequently carried out in sections; that is, after the concrete pouring of the current section is completed, the formwork must be promptly dismantled, and the wall moved to the next construction section for pouring.

[0003] In traditional construction methods, the dismantling and movement of formwork largely rely on manual operation, which is relatively inefficient. In some construction projects, tracks are laid on the ground and rollers are installed at the bottom of the formwork, allowing for rapid movement by sliding the rollers along the tracks. While this approach reduces the difficulty of moving formwork and improves construction efficiency to some extent, in practical applications, the complexity of ground conditions often limits track laying. In some special terrains or complex geological conditions, track laying is quite difficult.

[0004] Furthermore, for retaining walls of considerable height, construction often requires layered pouring along the vertical direction. When constructing intermediate layers, the method of laying guide rails on the ground is no longer suitable because the bottom of the formwork is suspended at a certain height.

[0005] Therefore, designing a movable retaining wall formwork that can adapt to the needs of layered pouring construction and has high flexibility and adaptability has become a technical problem that urgently needs to be solved in the field of retaining wall construction. Summary of the Invention

[0006] In view of the shortcomings of related technologies, the present invention provides a movable retaining wall formwork and a retaining wall construction process to realize the movement of the movable retaining wall formwork along the construction direction of the retaining wall.

[0007] This invention provides a movable retaining wall formwork for casting an upper retaining wall; the retaining wall is cast in sections along its length and in layers along its height; the retaining wall formwork includes:

[0008] The gantry is located above the retaining wall;

[0009] Two side formworks are arranged opposite each other along the thickness direction of the retaining wall and along the length direction of the retaining wall; the top of the side formworks is connected to the gantry frame, and the bottom of the side formworks is provided with a track component that extends along the length direction of the retaining wall.

[0010] Rollers are located on both sides of the retaining wall in the thickness direction; the rollers are connected to the lower retaining wall, and the bottom surfaces of the rollers and the track components are in contact with each other;

[0011] When the roller rotates around its axis, the roller and the track component move relative to each other, causing the track component to drive the side formwork and the gantry to move along the length of the retaining wall.

[0012] This technical solution uses a gantry to connect two side forms into a whole. Track components are installed at the bottom of the side forms, and rollers are installed on the outer side of the first wall of the lower retaining wall. The relative movement between the rollers and the track components causes the track components to move the side forms and the gantry along the length of the retaining wall, thereby realizing the overall movement of the retaining wall formwork.

[0013] In some embodiments, load-bearing members are provided on both sides of the lower retaining wall in the thickness direction, and rollers are rotatably connected to the load-bearing members.

[0014] In some embodiments, a drive element is also included, which is mounted on the carrier and connected to the roller for driving the roller to rotate.

[0015] This technical solution uses a driving component to drive the rollers to rotate, thereby causing relative movement between the rollers and the track components, and thus realizing the overall movement of the retaining wall formwork.

[0016] In some embodiments, the lower retaining wall is provided with a reserved hole, the reserved hole being set at a height lower than the top height of the first retaining wall, the reserved hole extending along the thickness direction of the retaining wall, one end of the bearing member being inserted into the reserved hole, and the other end of the bearing member being set through the reserved hole.

[0017] In some embodiments, a limiting part is provided at one end of the carrier outside the reserved hole. The limiting part is correspondingly provided with the track component to limit the engagement position between the track component and the roller.

[0018] This technical solution sets a limiting part on the bearing component, so that the limiting part is set in correspondence with the track component, thereby limiting the cooperation position between the track component and the roller, constraining the movement path of the track component, and preventing the track component from deviating from its movement path.

[0019] In some embodiments, the reserved hole is a drainage hole for the lower retaining wall.

[0020] This technical solution uses the drainage holes of the lower retaining wall as reserved holes to install load-bearing components, eliminating the need to set additional reserved holes in the lower retaining wall. This not only reduces the construction steps of the retaining wall but also increases its strength.

[0021] In some embodiments, the rollers are configured in two sets, with the two sets of rollers corresponding to each other on both sides of the retaining wall in the thickness direction. Each set of rollers includes several rollers, which are distributed along the length direction of the retaining wall. Each track component is in contact with multiple rollers simultaneously.

[0022] In addition, the present invention also provides a retaining wall construction process, including the aforementioned movable retaining wall formwork; the retaining wall construction process includes the pouring of the lower retaining wall and the pouring of the upper retaining wall, the pouring of the upper retaining wall including the following steps:

[0023] Install load-bearing components on the lower retaining wall, and install the drive components and rollers on the load-bearing components;

[0024] The crane lifts the side formwork onto the track components and places them on the rollers via the gantry frame;

[0025] Concrete is poured into the retaining wall formwork to complete the pouring of the current construction section. After the current construction section is completed, the drive unit drives the rollers to rotate, causing the track components to move the side formwork and gantry horizontally relative to the rollers, so that the side formwork and gantry can move to the next construction section for pouring.

[0026] This technical solution involves installing a load-bearing component on the lower retaining wall, and then installing a drive component and rollers on the load-bearing component. This allows the track component on the side formwork to contact the rollers, and the drive component drives the rollers to rotate, causing relative movement between the track component and the rollers, thereby enabling the movement of the retaining wall formwork.

[0027] In some embodiments, the construction of the lower retaining wall is completed before the construction of the upper retaining wall is carried out; when the lower retaining wall is poured, reserved holes are reserved on the wall surface along its length, and the reserved holes are used to install load-bearing components when the upper retaining wall is constructed.

[0028] In some embodiments, the side formwork is connected to the current construction section by top screws. After the current construction section is completed, the top screws are removed first, and then the side formwork and gantry are moved. The load-bearing components are installed in the reserved holes by expansion bolts.

[0029] Based on the above technical solution, the movable retaining wall formwork in this embodiment of the invention can move along the construction direction of the retaining wall when pouring the upper retaining wall, which improves construction efficiency, and the overall structure is simple and easy to operate.

[0030] The retaining wall construction process in this embodiment of the invention effectively solves the problem that the retaining wall formwork is not easy to move when pouring the upper retaining wall. The construction process is simple, easy to operate, and has high construction efficiency. Attached Figure Description

[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0049] In the description of this invention, it should be understood that the terms "center", "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0050] The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.

[0051] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0052] The retaining wall 1 is poured in sections along its length. The length of the retaining wall 1 is the construction direction of the retaining wall 1. The retaining wall 1 can be divided into the first construction section, the second construction section, and so on along its construction direction. The end of the first construction section is the beginning of the second construction section, the end of the second construction section is the beginning of the third construction section, and so on.

[0053] like Figure 1 As shown, retaining wall 1 is poured in layers along its height direction. Retaining wall 1 can be divided into a first layer retaining wall 11, a second layer retaining wall 12, and so on. The first layer retaining wall 11 is located on the ground, the second layer retaining wall 12 is located on the first layer retaining wall 11, and the top of the first layer retaining wall 11 is the bottom of the second layer retaining wall 12. The third layer retaining wall 13 is located on the second layer retaining wall 12, and the top of the second layer retaining wall 12 is the bottom of the third layer retaining wall 13, and so on.

[0054] For ease of description, in two adjacent retaining walls 1, the one located above is called the upper retaining wall, and the one located below is called the lower retaining wall; the wall surface of retaining wall 1 extending along its length direction is called the first wall surface, and the wall surface of retaining wall 1 extending along its thickness direction is called the second wall surface.

[0055] As attached Figure 2 and Figure 3 As shown, in an illustrative embodiment of the movable retaining wall formwork of the present invention, the movable retaining wall formwork is used for casting the upper retaining wall; the movable retaining wall formwork includes at least a side formwork 2, a gantry 3, a track component 8, and rollers 6.

[0056] The aforementioned movable retaining wall template has side molds 2 corresponding to the first wall surface; there are two side molds 2, which are arranged opposite each other along the thickness direction of the retaining wall 1 and along the length direction of the retaining wall 1; the top of the side molds 2 is connected to the gantry 3, and the bottom of the side molds 2 is provided with track components 8.

[0057] During concrete pouring, due to the fluidity of the concrete and the vibration, the side formwork 2 will be subjected to a large lateral pressure, causing the two side formwork 2 to tend to move away from each other.

[0058] like Figure 3 As shown, the side formwork 2 is connected to a top screw 21. The side formwork 2 is connected to the current construction section of the retaining wall 1 via the top screw 21. The top screw 21 can firmly support the side formwork 2 in the predetermined position to prevent the side formwork 2 from shifting or deforming during concrete pouring. After the current construction section is completed, the top screw 21 needs to be removed to separate the side formwork 2 from the completed retaining wall 1.

[0059] like Figure 4 As shown, the above-mentioned movable retaining wall formwork also includes end molds 4. End molds 4 and the second wall should be provided. There are two end molds 4. End molds 4 are connected to the gantry 3 and the side molds 2. End molds 4 and side molds 2 together define the pouring space. By pouring concrete into the pouring space, a section of the retaining wall 1 is formed.

[0060] The end formwork 4 includes a front end formwork and a rear end formwork, which are arranged opposite each other along the length of the retaining wall 1. The front end formwork and the rear end formwork are arranged one-to-one with the two second wall surfaces. The front end formwork and the rear end formwork are respectively arranged along the thickness direction of the retaining wall 1 and are respectively connected to the gantry 3. Among them, the front end formwork is used to form the first end face of the first construction section. The rear end formwork is used to form the last end face of the construction section.

[0061] During construction, when pouring the first construction section, the front mold, the rear mold, and the two side molds 2 together form the pouring space. When pouring the second construction section, the end face of the first construction section can be defined together with the two side molds 2 and the rear mold to form the pouring space. Therefore, when pouring the first construction section, the front mold, the rear mold, and the two side molds 2 need to be used at the same time. When pouring the second construction section and subsequent construction sections, the front mold is no longer needed. This is common knowledge in the field and will not be elaborated further.

[0062] It should be noted that in this embodiment, the front-end module and the back-end module are collectively referred to as end module 4. End module 4 can refer to the front-end module, the back-end module, or both the front-end module and the back-end module.

[0063] In some embodiments, such as Figure 4 As shown, the end formwork 4 is provided with an ear 41, and a winch 9 is installed on the gantry 3. The winch 9 is connected to the ear 41 by a rope. The winch 9 moves the end formwork 4 up and down along the height direction of the retaining wall 1 by winding or releasing the rope.

[0064] like Figure 6 As shown, in the above-mentioned movable retaining wall formwork, the gantry 3 is used to connect the side formwork 2 and the end formwork 4. The gantry 3 includes a front truss 31, a rear truss 32, and two side trusses 33. The front truss 31 and the rear truss 32 are arranged opposite each other along the length direction of the retaining wall 1, and the two side trusses 33 are arranged opposite each other along the thickness direction of the retaining wall 1. The front truss 31 is corresponding to the front end formwork, and the front end formwork is connected to the front truss 31. The rear truss 32 is corresponding to the rear end formwork, and the rear end formwork is connected to the rear truss 32. The two side trusses 33 are corresponding to the two side formwork 2 one by one, and the two side formwork 2 are correspondingly connected to the two side trusses 33.

[0065] The gantry 3 also includes an intermediate truss 35, the two ends of which are connected to the two side trusses 33 respectively, to increase the connection strength of the two side trusses 33.

[0066] The gantry 3 also includes a diagonal brace 34, one end of which is connected to the connection between the intermediate truss 35 and one of the side trusses 33, and the other end of which is connected to the connection between the other side truss 33 and the front truss 31 or the rear truss 32.

[0067] In some embodiments, two diagonal supports 34 are provided, and the two diagonal supports 34 are arranged symmetrically about the intermediate truss 35 in the horizontal plane.

[0068] The aforementioned movable retaining wall formwork uses a gantry 3 to connect two side molds 2, thereby constraining the two side molds 2 and preventing them from moving away from each other during concrete pouring. The gantry 3 is also connected to the side molds 2 and the end molds 4, which can also be connected to the side molds 2 and the end molds 4 as a whole, facilitating the overall movement of the retaining wall formwork.

[0069] In the above-mentioned movable retaining wall formwork, such as Figure 3 and Figure 5 As shown, the track component 8 is located at the bottom of the side formwork 2 and extends along the length of the retaining wall 1.

[0070] In some embodiments, the track member 8 is an I-beam, and the track member 8 is welded to the bottom of the side mold 2.

[0071] In the above-mentioned movable retaining wall formwork, such as Figure 3 and Figure 5 As shown, rollers 6 are located on both sides of the thickness direction of retaining wall 1; rollers 6 are connected to the lower retaining wall, and rollers 6 are in contact with the bottom surface of track component 8; when rollers 6 rotate around their axis, rollers 6 and track component 8 move relative to each other, causing track component 8 to drive side formwork 2 and gantry 3 to move along the length direction of retaining wall 1.

[0072] The aforementioned movable retaining wall formwork uses a track component 8 at the bottom of the side formwork 2 and rollers 6 on the outer side of the first wall of the lower retaining wall. The relative movement between the rollers 6 and the track component 8 causes the track component 8 to drive the side formwork 2 and the gantry 3 to move along the length of the retaining wall 1, thereby realizing the movement of the side formwork 2 and the gantry 3.

[0073] It should be noted that the rollers 6 are set in two sets, and the two sets of rollers 6 are set on both sides of the thickness direction of the retaining wall 1. The two sets of rollers 6 are set one-to-one with the track components 8 at the bottom of the two side molds 2 to increase the movement effect of the two side molds 2.

[0074] It should also be noted that each set of rollers 6 includes multiple rollers 6, which are distributed along the length of the retaining wall 1, and the same track component 8 contacts multiple rollers 6 in the same set at the same time.

[0075] To facilitate the installation of roller 6, such as Figure 3 As shown, the lower retaining wall is provided with a bearing member 5, which is used to install rollers 6. The bearing member 5 is connected to the first wall surface, and the rollers 6 are rotatably connected to the bearing member 5.

[0076] In some embodiments, such as Figure 3 As shown, the bearing member 5 is provided with a bushing 62 at the end away from the retaining wall 1, and the roller 6 is sleeved on the outer periphery of the bushing 62. The roller 6 and the bushing 62 are coaxially arranged, and the rotation axis of the roller 6 is arranged along the thickness direction of the retaining wall 1.

[0077] In some embodiments, the support member 5 is a steel pipe.

[0078] To facilitate the installation of the bearing component 5, the lower retaining wall is provided with a reserved hole 101. The reserved hole 101 extends along the thickness direction of the retaining wall 1. One end of the bearing component 5 is inserted into the reserved hole 101, and the other end of the bearing component 5 is set through the reserved hole 101. The roller 6 is connected to the end of the bearing component 5 that extends through the reserved hole 101.

[0079] It should be noted that the height of the reserved hole 101 is lower than the top height of the first retaining wall 11, so that when the track piece 8 contacts the roller 6, the lower end of the side formwork 2 overlaps with at least part of the lower retaining wall, so as to prevent concrete leakage when pouring the upper retaining wall.

[0080] It should also be noted that there are multiple reserved holes 101, which are distributed along the length of the retaining wall 1.

[0081] like Figure 3 As shown, the bearing member 5 is connected to the lower retaining wall by expansion bolts 51. Since the side formwork 2 is connected to the upper concrete by top screws 21, when the side formwork 2 is disassembled, the bottom of the side formwork 2 will also move away from the first wall surface. By loosening the expansion bolts 51, the side formwork 2 can be moved as a whole, and the connection effect between the bearing member 5 and the lower retaining wall can also be guaranteed.

[0082] A limiting part 52 is provided at one end of the support member 5 outside the reserved hole 101. The limiting part 52 is correspondingly provided with the track member 8 and is used to limit the mating position of the track member 8 and the roller 6, so as to constrain the movement path of the track member 8 and prevent the track member 8 from deviating from its movement path. It should be noted that the circumferential dimension of the limiting part 52 is larger than the circumferential dimension of the roller 6. The limiting part 52 abuts against the track member 8 to prevent the track member 8 from moving away from the first wall surface.

[0083] In some embodiments, the reserved hole 101 is a drainage hole of the lower retaining wall. This is because some lower retaining walls are provided with drainage holes, and the drainage holes are set in the direction of the thickness of the retaining wall 1. Therefore, when the lower retaining wall is provided with drainage holes, the drainage holes of the lower retaining wall can be used as the reserved hole 101, and the bearing member 5 can be installed using the drainage holes. There is no need to set additional reserved holes 101 in the lower retaining wall, which can not only reduce the construction steps of the retaining wall 1, but also increase the strength of the retaining wall 1.

[0084] like Figure 3 As shown, the aforementioned movable retaining wall formwork also includes a driving component 7, which is installed on the bearing component 5 and connected to the roller 6 for driving the roller 6 to rotate around its axis. The driving component 7 is connected to a first gear 71, and the roller 6 is connected to a second gear 61. The first gear 71 and the second gear 61 mesh with each other to drive the roller 6 to rotate.

[0085] In some embodiments, the drive element 7 is a motor or electric motor.

[0086] In some other embodiments, the drive member 7 is located above the support member 5, and the support member 5 applies a supporting force to the drive member 7. This not only facilitates the installation of the drive member 7 on the support member 5, but also increases the stability and reliability of the drive member 7 on the support member 5.

[0087] It should be noted that when there are two sets of rollers 6, there are also two drive components 7. The two drive components 7 are set one-to-one with the two sets of rollers 6, and the two drive components 7 drive the corresponding rollers 6 to move simultaneously.

[0088] It should also be noted that among the multiple rollers 6 in contact with the same track component 8, not all rollers 6 need to be connected to the drive component 7. One roller 6 can be selected to be connected to the drive component 7. The roller 6 connected to the drive component 7 is the driving wheel, and the other rollers 6 are the driven wheels. This can avoid motion interference caused by multiple rollers 6 acting as driving wheels and ensure the movement effect of the side mold 2.

[0089] In actual construction, retaining wall 1 is usually constructed by first pouring the lower retaining wall in sections, and then pouring the upper retaining wall in sections. Since the rollers 6 are installed on the lower retaining wall, they cannot be installed during the pouring of the first retaining wall 11. This prevents the movable retaining wall from functioning effectively and also prevents the movable retaining wall formwork from moving. Therefore, in some embodiments, conventional retaining wall formwork is used during the construction of the first retaining wall 11. Guide rails are laid on the ground, and wheels are installed at the bottom of the retaining wall formwork. The movement of the retaining wall formwork is achieved by the wheels moving along the guide rails. This is existing technology and will not be elaborated further.

[0090] In the above illustrative embodiment, the movable retaining wall formwork connects the two side forms 2 and the rear formwork into a whole through the gantry 3, and a track component 8 is set at the bottom of the side formwork 2 and a roller 6 is set on the outer side of the first wall of the lower retaining wall. By utilizing the relative movement between the roller 6 and the track component 8, the track component 8 drives the side formwork 2 and the gantry 3 to move along the length direction of the retaining wall 1, thereby realizing the overall movement of the retaining wall formwork.

[0091] The aforementioned movable retaining wall formwork can be moved along the construction direction of retaining wall 1 when the upper retaining wall is being poured, which facilitates the segmented pouring of the upper retaining wall. Moreover, the overall structure is simple, easy to operate, and has high overall moving efficiency and good moving effect.

[0092] Based on the aforementioned movable retaining wall formwork, this invention also provides a retaining wall construction process, which includes the aforementioned movable retaining wall formwork. The retaining wall construction process includes the pouring of a lower retaining wall and the pouring of an upper retaining wall. The pouring of the upper retaining wall includes the following steps:

[0093] Install the bearing component 5 on the lower retaining wall, and install the drive component 7 and roller 6 on the bearing component 5 respectively;

[0094] The crane lifts the side mold 2 onto the track component 8 and places it on the roller 6 via the gantry 3;

[0095] Concrete is poured into the retaining wall formwork to complete the pouring of the current construction section. After the current construction section is completed, the drive component 7 drives the roller 6 to rotate, so that the track component 8 drives the side formwork 2 and the gantry 3 to move horizontally relative to the roller 6, so that the side formwork 2 and the gantry 3 can move to the next construction section for pouring of the next construction section.

[0096] The above-mentioned retaining wall construction process involves installing a bearing member 5 on the lower retaining wall, and installing a driving member 7 and rollers 6 on the bearing member 5. This allows the track member 8 on the side formwork 2 to contact the rollers 6. The driving member 7 drives the rollers 6 to rotate, causing relative movement between the track member 8 and the rollers 6. This allows the retaining wall formwork to move along the construction direction when pouring the upper retaining wall, thereby improving construction efficiency and facilitating segmented construction of the retaining wall. The retaining wall formwork has good movement effect, high movement efficiency, and will not damage the already constructed parts of the retaining wall 1.

[0097] It should be noted that the construction of the upper retaining wall is carried out after the construction of the lower retaining wall is completed. When the lower retaining wall is poured, a reserved hole 101 is reserved on the wall surface of the retaining wall 1 along its length direction. The reserved hole 101 is used to install the bearing component 5 when the upper retaining wall is constructed.

[0098] It should also be noted that the side formwork 2 is connected to the current construction section by the top screw 21. After the current construction section is completed, the top screw 21 is removed first, and then the side formwork 2 and the gantry 3 are moved; the bearing component 5 is installed in the reserved hole 101 by the expansion bolt 51.

[0099] The following section takes retaining wall 1, which includes a first layer of retaining wall 11, a second layer of retaining wall 12, and a third layer of retaining wall 13, as an example to introduce the construction process of retaining wall 1 in detail.

[0100] The construction process of retaining wall 1 includes the construction of the first layer retaining wall 11, the second layer retaining wall 12, and the third layer retaining wall 13. The construction of the first layer retaining wall 11 is carried out first, followed by the construction of the second layer retaining wall 12, and finally the construction of the third layer retaining wall 13. Among them, the first layer retaining wall 11 is poured using conventional retaining wall formwork, while the construction of the second layer retaining wall 12 and the third layer retaining wall 13 uses the aforementioned movable retaining wall formwork.

[0101] The construction process of the first retaining wall 11 is a conventional technique in this field and will not be described in detail here.

[0102] The construction process of the second retaining wall 12 includes the following steps:

[0103] Install the drive component 7 and roller 6 onto the bearing component 5, install the bearing component 5 into the drainage hole on the first retaining wall 11, and connect the bearing component 5 to the first retaining wall 11 through expansion bolts 51.

[0104] The crane lifts the side mold 2 and the required end mold 4 to the designated height through the gantry 3, so that the track piece 8 at the bottom of the side mold 2 is placed on the corresponding roller 6.

[0105] The side formwork 2, end formwork 4 and the top of the first retaining wall 11 together define the pouring space. Concrete is poured into the pouring space to complete the pouring of the current construction section. After the current construction section is completed, the top screw 21 connecting the side formwork 2 and the current construction section is removed to separate the retaining wall formwork from the current construction section.

[0106] The driving component 7 drives the roller 6 to rotate, causing the track component 8 to move relative to the roller 6. This causes the track component 8 to move the side formwork 2 and the gantry 3 horizontally relative to the roller 6, allowing the side formwork 2, the rear formwork, and the gantry 3 to move to the next construction section for pouring.

[0107] The construction process of the third retaining wall 13 includes the following steps:

[0108] Install the drive component 7 and roller 6 onto the bearing component 5, install the bearing component 5 into the drainage hole on the second retaining wall 12, and connect the bearing component 5 to the second retaining wall 12 by expansion bolts 51.

[0109] The crane lifts the side mold 2 and the required end mold 4 to the designated height through the gantry 3, so that the track piece 8 at the bottom of the side mold 2 is placed on the corresponding roller 6.

[0110] The side formwork 2, end formwork 4, and the top of the second retaining wall 12 together define a pouring space. Concrete is poured into the pouring space to complete the pouring of the current construction section. After the current construction section is completed, the top screw 21 connecting the side formwork 2 and the current construction section is removed to separate the retaining wall formwork from the current construction section.

[0111] The driving component 7 drives the roller 6 to rotate, causing the track component 8 to move relative to the roller 6. This causes the track component 8 to move the side formwork 2 and the gantry 3 horizontally relative to the roller 6, allowing the side formwork 2, the rear formwork, and the gantry 3 to move to the next construction section for pouring.

[0112] It should be noted that the second retaining wall 12 and the third retaining wall 13 are the upper retaining walls and their construction processes are the same. The first retaining wall 11 is the lower retaining wall and its construction process is different from that of the second retaining wall 12 and the third retaining wall 13.

[0113] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0114] The above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
