Description

Technical Field

[0001] The invention belongs to the technical field of retaining wall construction, and in particular relates to a movable retaining wall template and a retaining wall construction process. Background Art

[0002] Retaining walls, as a vital structural facility in civil engineering, have the core function of supporting soil or rock, effectively resisting the invasion of external loads such as gravity, water pressure and wind pressure, and preventing it from sliding or collapsing. Retaining walls are usually constructed by pouring concrete using formwork. Since retaining walls often extend for a long time, construction often adopts a segmented operation method, that is, after the concrete pouring of the current retaining wall is completed, the formwork needs to be removed in time and moved forward to the next construction section for pouring.

[0003] In traditional construction methods, the disassembly and movement of templates mostly rely on manual operations, which is relatively inefficient. In some constructions, tracks are laid on the ground, rollers are installed at the bottom of the template, and the template is quickly moved by sliding along the track with the help of the rollers. Although this approach reduces the difficulty of template movement and improves construction efficiency to a certain extent, in actual applications, the complexity of ground conditions often limits the laying of tracks. Track laying is more difficult in some special terrains or complex geological conditions.

[0004] In addition, for high retaining walls, it is often necessary to cast in layers along the height direction during construction. When constructing the middle layer, since the bottom of the formwork is suspended at a certain height, the method of laying guide rails on the ground is no longer applicable.

[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 needs to be urgently solved in the current retaining wall construction field. Summary of the invention

[0006] In view of the deficiencies existing in the related art, the present invention provides a movable retaining wall formwork and a retaining wall construction process to achieve the movement of the movable retaining wall formwork along the retaining wall construction direction.

[0007] The present invention provides a movable retaining wall template, which is used for casting an upper retaining wall; the retaining wall is cast in sections along its length direction, and the retaining wall is cast in layers along its height direction; the retaining wall template comprises:

[0008] a portal frame, which is located above the retaining wall;

[0009] Two side molds, the two side molds are arranged opposite to each other along the thickness direction of the retaining wall, and the side molds are arranged along the length direction of the retaining wall; the top of the side mold is connected to the door frame, and the bottom of the side mold is provided with a track member, and the track member extends along the length direction of the retaining wall;

[0010] Rollers are arranged on both sides of the retaining wall in the thickness direction; the rollers are connected to the lower retaining wall, and the rollers are in contact with the bottom surface of the track member;

[0011] When the roller rotates around its axis, the roller and the track member move relative to each other, so that the track member drives the side form and the portal frame to move along the length direction of the retaining wall.

[0012] The technical solution sets up a gantry, uses the gantry to connect the two side forms into a whole, sets a track member at the bottom of the side form, sets a roller on the outer side of the first wall surface of the lower retaining wall, and utilizes the relative movement between the roller and the track member to make the track member drive the side form and the gantry to move along the length direction of the retaining wall, thereby realizing the overall movement of the retaining wall formwork.

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

[0014] In some of the embodiments, a driving member is further included, wherein the driving member is mounted on the supporting member and connected to the roller to drive the roller to rotate.

[0015] The technical solution provides a driving member, which is used to drive the roller to rotate, so that the roller and the track member move relative to each other, thereby realizing the overall movement of the retaining wall template.

[0016] In some of the embodiments, a reserved hole is provided in the lower retaining wall, and a height of the reserved hole is lower than a top height of the first retaining wall. The reserved hole extends along the thickness direction of the retaining wall, and one end of the bearing member is inserted into the reserved hole, and the other end of the bearing member is arranged to pass through the reserved hole.

[0017] In some of the embodiments, a limiting portion is provided at one end of the bearing member disposed outside the reserved hole, and the limiting portion is disposed corresponding to the track member and is used to limit the matching position of the track member and the roller.

[0018] The technical solution provides a limit portion on the bearing member, so that the limit portion and the track member are provided correspondingly, so as to limit the matching position of the track member and the roller, constrain the movement path of the track member, and prevent the track member from deviating from its movement path.

[0019] In some of the embodiments, the reserved holes are drainage holes of the lower retaining wall.

[0020] This technical solution uses the drainage holes of the lower retaining wall as reserved holes and utilizes the drainage holes to install the bearing members, without the need to additionally provide reserved holes in the lower retaining wall. This can not only reduce the construction steps of the retaining wall, but also increase the strength of the retaining wall.

[0021] In some embodiments, the rollers are arranged in two groups, and the two groups of rollers are arranged on both sides of the thickness direction of the retaining wall respectively. Each group of rollers includes a plurality of rollers, and the plurality of rollers are distributed along the length direction of the retaining wall; each track member is in contact with a plurality of rollers at the same time.

[0022] In addition, the present invention also provides a retaining wall construction process, comprising the above-mentioned movable retaining wall formwork; the retaining wall construction process comprises casting of a lower retaining wall and casting of an upper retaining wall, and the casting of the upper retaining wall comprises the following steps:

[0023] Install the bearing member on the lower retaining wall, and install the driving member and the roller on the bearing member;

[0024] The crane hoists the side form to the track piece through the gantry and places it on the rollers;

[0025] Concrete is poured on the retaining wall formwork to complete the pouring of the current construction section. After the pouring of the current construction section is completed, the driving member drives the roller to rotate, so that the track member drives the side formwork and the gantry to move horizontally relative to the roller, so that the side formwork and the gantry move to the next construction section for pouring of the next construction section.

[0026] This technical solution installs a bearing member on the lower retaining wall, and installs a driving member and a roller on the bearing member, so that the track member and the roller provided on the side form are in contact with each other, and the driving member drives the roller to rotate, so that the track member and the roller move relative to each other, thereby realizing the movement of the retaining wall formwork.

[0027] In some of the embodiments, after the construction of the lower retaining wall is completed, the upper retaining wall is constructed; when the lower retaining wall is poured, reserved holes are reserved on the wall surface of the retaining wall along its length direction, and the reserved holes are used to install bearing parts when the upper retaining wall is constructed.

[0028] In some of the embodiments, the side form is connected to the current construction section through a top screw. After the current construction section is completed, the top screw is removed first, and then the side form and the door frame are moved; the bearing member is installed in the reserved hole through the expansion bolt.

[0029] Based on the above technical solution, the movable retaining wall formwork in the embodiment of the present invention can be moved along the construction direction of the retaining wall when pouring the upper retaining wall, thereby improving the construction efficiency, and the overall structure is simple and easy to operate.

[0030] The retaining wall construction process in the embodiment of the present invention effectively solves the problem that the retaining wall template is inconvenient to move when pouring the upper retaining wall. The construction process is simple, easy to operate and has high construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

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

[0051] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] The retaining wall 1 is cast in sections along its length direction. The length direction of the retaining wall 1 is the construction direction of the retaining wall 1. The retaining wall 1 can be divided into a first construction section, a second construction section, etc. along its construction direction, wherein the tail end of the first construction section is the head end of the second construction section, the tail end of the second construction section is the head end of the third construction section, and so on.

[0053] like Figure 1 As shown, the retaining wall 1 is cast in layers along its height direction, and the retaining wall 1 can be divided into a first layer retaining wall 11, a second layer retaining wall 12, ... along its height direction, wherein the first layer retaining wall 11 is arranged on the ground, the second layer retaining wall 12 is arranged 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 arranged 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 the sake of convenience, the upper layer of two adjacent retaining walls 1 is called the upper retaining wall, and the lower layer is called the lower retaining wall; the wall surface of the retaining wall 1 extending along its length direction is called the first wall surface, and the wall surface of the 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 an upper retaining wall; the movable retaining wall formwork at least includes a side formwork 2, a door frame 3, a track member 8 and a roller 6.

[0056] In the above-mentioned movable retaining wall formwork, the side form 2 is arranged corresponding to the first wall surface; the side form 2 is arranged in two, the two side form 2 are arranged opposite to each other along the thickness direction of the retaining wall 1, and the side form 2 is arranged along the length direction of the retaining wall 1; the top of the side form 2 is connected to the door frame 3, and the bottom of the side form 2 is provided with a track member 8.

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

[0058] like Figure 3 As shown, the side form 2 is connected with a top screw 21, and the side form 2 is connected to the current construction section of the retaining wall 1 through the top screw 21. The top screw 21 can firmly support the side form 2 at a predetermined position to prevent the side form 2 from shifting or deforming when pouring concrete. After the current construction section is poured, the top screw 21 needs to be removed to separate the side form 2 from the poured retaining wall 1.

[0059] like Figure 4 As shown, the above-mentioned movable retaining wall formwork also includes an end formwork 4, which should be set with the second wall surface, and two end forms 4 are set. The end formwork 4 is connected to the door frame 3 and the side formwork 2. The end formwork 4 and the side formwork 2 jointly define a casting space, and concrete is poured into the casting space to cast and form one section of the retaining wall 1.

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

[0061] During construction, when pouring the first construction section, the front end mold, the rear end mold and the two side molds 2 together form a pouring space. When pouring the second construction section, the tail end face of the first construction section can be jointly defined with the two side molds 2 and the rear end mold to form a pouring space. Therefore, when pouring the first construction section, it is necessary to use the front end mold, the rear end mold and the two side molds 2 at the same time. When pouring the second construction section and the subsequent construction sections, the front end mold is no longer needed. This is common knowledge and technology in the field and will not be repeated here.

[0062] It should be noted that, in this embodiment, the front-end mold and the rear-end mold are collectively referred to as the end mold 4 , and the end mold 4 may refer to the front-end mold, the rear-end mold, or both the front-end mold and the rear-end mold.

[0063] In some embodiments, Figure 4 As shown, the end mold 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 through a rope. The winch 9 reels in or releases the rope to move the end mold 4 up and down along the height direction of the retaining wall 1.

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

[0065] The portal frame 3 further includes a middle truss 35 , two ends of which are correspondingly connected to the two side trusses 33 , so as to increase the connection firmness of the two side trusses 33 .

[0066] The portal frame 3 further includes an oblique support 34 , one end of which is connected to the connection between the middle truss 35 and one of the side trusses 33 , and the other end of the oblique support 34 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 symmetrically arranged about the middle truss 35 in a horizontal plane.

[0068] The above-mentioned movable retaining wall formwork is provided with a door frame 3, and the two side forms 2 are connected by the door frame 3, so that the door frame 3 constrains the two side forms 2 to prevent the two side forms 2 from moving away from each other when pouring concrete; the door frame 3 is connected with the side forms 2 and the end form 4, and the side form 2 and the end form 4 can also be connected as a whole, so as to facilitate the overall movement of the retaining wall formwork.

[0069] In the above movable retaining wall formwork, Figure 3 and Figure 5 As shown, the track member 8 is arranged at the bottom of the side form 2 , and the track member 8 extends along the length direction 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 movable retaining wall formwork, Figure 3 and Figure 5 As shown, the rollers 6 are arranged on both sides of the retaining wall 1 in the thickness direction; the rollers 6 are connected to the lower retaining wall, and the rollers 6 and the bottom surfaces of the track members 8 are in contact with each other; when the rollers 6 rotate around their axes, the rollers 6 and the track members 8 move relative to each other, so that the track members 8 drive the side molds 2 and the door frames 3 to move along the length direction of the retaining wall 1.

[0072] The above-mentioned movable retaining wall formwork is achieved by arranging a track member 8 at the bottom of the side form 2 and a roller 6 on the outer side of the first wall surface of the lower retaining wall. The relative movement between the roller 6 and the track member 8 is utilized to make the track member 8 drive the side form 2 and the gantry 3 to move along the length direction of the retaining wall 1, thereby realizing the movement of the side form 2 and the gantry 3.

[0073] It should be noted that the rollers 6 are provided in two groups, and the two groups of rollers 6 are correspondingly provided on both sides of the thickness direction of the retaining wall 1 . The two groups of rollers 6 are provided in one-to-one correspondence with the track members 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 group of rollers 6 includes a plurality of rollers 6 , and the plurality of rollers 6 are distributed along the length direction of the retaining wall 1 , and the same track member 8 is in contact with the plurality of rollers 6 of the same group at the same time.

[0075] In order to facilitate the installation of the roller 6, Figure 3 As shown, the lower retaining wall is provided with a bearing member 5, the bearing member 5 is used to install a roller 6, the bearing member 5 is connected to the first wall surface, and the roller 6 is rotatably connected to the bearing member 5.

[0076] In some embodiments, Figure 3 As shown, a shaft sleeve 62 is provided at one end of the bearing member 5 away from the retaining wall 1 , and a roller 6 is sleeved on the outer periphery of the shaft sleeve 62 . The roller 6 and the shaft sleeve 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] In order to facilitate the installation of the bearing member 5, the lower retaining wall is provided with a reserved hole 101, which extends along the thickness direction of the retaining wall 1. One end of the bearing member 5 is inserted into the reserved hole 101, and the other end of the bearing member 5 is arranged to pass through the reserved hole 101. The roller 6 is connected to the end of the bearing member 5 that passes through the reserved hole 101.

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

[0080] It should also be noted that the reserved holes 101 are provided in plurality, and the plurality of reserved holes 101 are distributed along the length direction of the retaining wall 1 .

[0081] like Figure 3 As shown, the bearing member 5 is connected to the lower retaining wall through the expansion bolts 51. Since the side form 2 is connected to the upper concrete layer through the top screw 21, when the side form 2 is removed, the bottom of the side form 2 will also move away from the first wall surface. By loosening the expansion bolts 51, the side form 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 portion 52 is provided at one end of the bearing member 5 disposed outside the reserved hole 101. The limiting portion 52 is disposed corresponding to the track member 8 and is used to limit the matching position of the track member 8 and the roller 6 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 portion 52 is greater than the circumferential dimension of the roller 6, and the limiting portion 52 and the track member 8 abut against each other to prevent the track member 8 from moving in a direction 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 arrangement direction of the drainage holes is arranged along the thickness direction 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 holes 101, and the bearing member 5 is installed by using the drainage holes. There is no need to additionally arrange the 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 movable retaining wall formwork further includes a driving member 7, which is mounted on the bearing member 5 and connected to the roller 6, and is used to drive the roller 6 to rotate around the axis of the roller 6. The driving member 7 is connected to a first gear 71, and the roller 6 is connected to a second gear 61, and the first gear 71 and the second gear 61 are meshed with each other, so that the driving member 7 drives the roller 6 to rotate.

[0085] In some embodiments, the driving member 7 is a motor or an electric machine.

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

[0087] It should be noted that when the rollers 6 are provided in two groups, two driving members 7 are also provided, and the two driving members 7 are provided in one-to-one correspondence with the two groups of rollers 6, and the two driving members 7 drive the corresponding rollers 6 to move simultaneously.

[0088] It should also be noted that, among the multiple rollers 6 contacting the same track member 8, it is not necessary for all the rollers 6 to be connected to the driving member 7. One of the rollers 6 can be selected to be connected to the driving member 7. The roller 6 connected to the driving member 7 is the driving wheel, and the other rollers 6 are driven wheels. This can avoid motion interference caused by multiple rollers 6 acting as driving wheels, thereby ensuring the movement effect of the side mold 2.

[0089] In actual construction of the retaining wall 1, the lower retaining wall is usually constructed by segmented pouring, and then the upper retaining wall is constructed by segmented pouring. Since the roller 6 is installed on the lower retaining wall, the roller 6 cannot be installed when pouring the first layer of retaining wall 11, and the above-mentioned movable retaining wall cannot be fully utilized, and the movable retaining wall template cannot be moved. Therefore, in some embodiments, a conventional retaining wall template is used during the construction of the first layer of retaining wall 11, and a guide rail is laid on the ground, and a walking wheel is set at the bottom of the retaining wall template. The retaining wall template is moved by the walking wheel moving along the guide rail. This is the prior art and will not be described in detail.

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

[0091] The movable retaining wall template can be moved along the construction direction of the retaining wall 1 when pouring the upper retaining wall, which is convenient for pouring the upper retaining wall in sections. The overall structure is simple and easy to operate, with high overall moving efficiency and good moving effect.

[0092] Based on the above movable retaining wall formwork, the present invention further provides a retaining wall construction process, which includes the above movable retaining wall formwork. The retaining wall construction process includes casting of a lower retaining wall and casting of an upper retaining wall, and the casting of the upper retaining wall includes the following steps:

[0093] Install a bearing member 5 on the lower retaining wall, and install a driving member 7 and a roller 6 on the bearing member 5 respectively;

[0094] The crane hoists the side mold 2 to the track member 8 through the door frame 3 and places it on the roller 6;

[0095] Concrete is poured on the retaining wall formwork to complete the pouring of the current construction section. After the pouring of the current construction section is completed, the driving member 7 drives the roller 6 to rotate, so that the track member 8 drives the side form 2 and the door frame 3 to move horizontally relative to the roller 6, so that the side form 2 and the door frame 3 move to the next construction section for pouring of the next construction section.

[0096] The above retaining wall construction process is to install a bearing member 5 on the lower retaining wall, and install a driving member 7 and a roller 6 on the bearing member 5, so that the track member 8 and the roller 6 provided on the side form 2 are in contact with each other, and the driving member 7 is used to drive the roller 6 to rotate, so that the track member 8 and the roller 6 move relative to each other, so that the retaining wall formwork can be moved along the construction direction when pouring the upper retaining wall, so as to improve the construction efficiency and facilitate the segmented construction of the retaining wall; the retaining wall formwork has a good moving effect and high moving efficiency and will not damage the completed part of the retaining wall 1.

[0097] It should be noted that the upper retaining wall is constructed after the lower retaining wall is constructed; when the lower retaining wall is cast, reserved holes 101 are reserved on the wall surface of the retaining wall 1 along its length direction, and the reserved holes 101 are used to install the bearing members 5 when the upper retaining wall is constructed.

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

[0099] The following takes the retaining wall 1 including the first retaining wall 11, the second retaining wall 12 and the third retaining wall 13 as an example to describe in detail the construction process of the retaining wall 1.

[0100] The construction process of the retaining wall 1 includes the construction of the first layer of retaining wall 11, the construction of the second layer of retaining wall 12 and the construction of the third layer of retaining wall 13. The first layer of retaining wall 11 is constructed first, then the second layer of retaining wall 12 is constructed, and finally the third layer of retaining wall 13 is constructed. The first layer of retaining wall 11 is cast using a conventional retaining wall formwork during construction, and the second layer of retaining wall 12 and the third layer of retaining wall 13 are constructed using the above-mentioned movable retaining wall formwork.

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

[0103] The driving member 7 and the roller 6 are installed on the bearing member 5 , and the bearing member 5 is installed on the drainage hole on the first layer of retaining wall 11 , so that the bearing member 5 is connected to the first layer of retaining wall 11 through the expansion bolts 51 .

[0104] The crane hoists the side mold 2 and the required end mold 4 to a specified height through the door frame 3, so that the track member 8 at the bottom of the side mold 2 is placed on the corresponding roller 6.

[0105] The side form 2, the end form 4 and the top of the first layer of retaining wall 11 are jointly defined to form a pouring space, and concrete is poured into the pouring space to complete the pouring of the current construction section. After the pouring of the current construction section is completed, the top screw 21 connecting the side form 2 and the current construction section is removed to separate the retaining wall formwork from the current construction section.

[0106] The driving member 7 drives the roller 6 to rotate, causing the track member 8 and the roller 6 to move relative to each other, thereby causing the track member 8 to drive the side form 2 and the gantry 3 to move horizontally relative to the roller 6, so that the side form 2, the rear end form and the gantry 3 are removed and moved to the next construction section for pouring the next construction section.

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

[0108] The driving member 7 and the roller 6 are installed on the bearing member 5 , and the bearing member 5 is installed on the drainage hole on the second retaining wall 12 , so that the bearing member 5 is connected to the second retaining wall 12 through the expansion bolts 51 .

[0109] The crane hoists the side mold 2 and the required end mold 4 to a specified height through the door frame 3, so that the track member 8 at the bottom of the side mold 2 is placed on the corresponding roller 6.

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

[0111] The driving member 7 drives the roller 6 to rotate, causing the track member 8 and the roller 6 to move relative to each other, thereby causing the track member 8 to drive the side form 2 and the gantry 3 to move horizontally relative to the roller 6, so that the side form 2, the rear end form and the gantry 3 are removed and moved to the next construction section for pouring the next construction section.

[0112] It should be noted that the second retaining wall 12 and the third retaining wall 13 are upper retaining walls, and their construction technology is the same. The first retaining wall 11 is a lower retaining wall, and its construction technology 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, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
