Description

Technical Field

[0001] This application relates to the technical field of civil engineering construction, and in particular to a retaining wall and its construction method. Background Technology

[0002] A retaining wall is a structure used to support and prevent soil from sliding or collapsing. It is commonly used in situations requiring soil stability, such as road slopes, bridge abutments, and river channels. Retaining walls support the soil by resisting the pressure exerted by the soil, maintaining slope stability and preventing the soil from sliding or becoming unstable due to gravity, rainwater erosion, or geological movements.

[0003] Currently, during the construction of retaining walls, it is necessary to first construct guide channels at predetermined locations. Guide channels are an important measure to guide the trenching equipment, and their completion quality directly affects the axis and elevation of the retaining wall. Guide channels are also an important measure to store slurry, stabilize the liquid level, maintain the stability of the upper soil, and prevent soil collapse.

[0004] In related technologies, during the construction of the guide channel, in order to control the wall thickness, it is necessary to set up formwork on both sides of the guide channel. In order to ensure that the formwork meets the stress requirements, both sides of the formwork are equipped with supports, horizontal bars, and diagonal braces to prevent the formwork from deforming and tilting outward. Currently, the diagonal braces of the formwork are mostly fixed at an angle between the formwork and the plane of the guide channel by a single support rod, and multiple rods need to be set at equal intervals to form a stable support structure. However, during the installation of these diagonal braces, since they are operated one by one, it cannot be guaranteed that the support force provided by each diagonal brace is the same. If the support force is different, it may lead to local deformation or tilting of the formwork, which will affect the overall quality of the retaining wall. Summary of the Invention

[0005] To address the problem of inconsistent support force in the formwork bracing during retaining wall construction, this application provides a retaining wall and its construction method.

[0006] Firstly, the retaining wall provided in this application adopts the following technical solution:

[0007] A retaining wall and its construction method, comprising:

[0008] The guide channel has vertical templates symmetrically arranged on both sides of its inner wall, and a retaining wall is poured between two adjacent vertical templates.

[0009] A diagonal bracing mechanism is used to support the vertical template. The diagonal bracing mechanism is located on the outside of the vertical template and includes a fixed plate, a base plate, a limiting plate, a template support plate, a transmission rod, an active plate, and a driven plate. The fixed plate is vertically fixed at the top center of the base plate. One end of the limiting plate is rotatably connected to the side wall of the fixed plate, and the other end is rotatably connected to the template support plate. The transmission rod is rotatably connected to the top of the fixed plate. One end of the active plate is fixed to the transmission rod. The two ends of the driven plate are respectively rotatably connected to the template support plate and the end of the active plate away from the transmission rod. The limiting plate and the driven plate are staggered and cross-arranged.

[0010] A linkage mechanism is used to drive two adjacent inclined support mechanisms to move synchronously. The linkage mechanism is set on the inclined support mechanism and includes a linkage rod. Both ends of the transmission rod have a polygonal slot recessed at their shaft centers. The linkage rod has a polygonal structure and is inserted into the polygonal slots of two adjacent transmission rods.

[0011] By adopting the above technical solution, the rotation of the transmission rod in the inclined bracing mechanism drives the active plate to rotate, which in turn drives the driven plate to move together and simultaneously drives the formwork support plate to move together. At the same time, the formwork support plate is limited by the limiting plate, causing the formwork support plate to deflect and tilt, thereby abutting against the vertical formwork and forming a supporting structure to support the vertical formwork. The thickness of the retaining wall is controlled by the vertical formwork and the outward tilting of the vertical formwork can be effectively prevented.

[0012] Meanwhile, the linkage mechanism enables adjacent transmission rods to move synchronously, thereby driving multiple formwork support plates to move synchronously and support the formwork. This ensures that the formwork is subjected to the same force at multiple points, meets the stress requirements, and prevents the formwork from deforming locally due to different forces, which would affect the quality of the retaining wall.

[0013] Optionally, the linkage mechanism further includes a support, a driving gear, and a driven gear. The support is fixed to the top of the side wall of the fixed plate, the driving gear is rotatably connected inside the support, and the driven gear is coaxially fixed on the transmission rod, and the driven gear meshes with the driving gear.

[0014] By adopting the above technical solution, the rotation of the driving gear drives the meshing and linkage of the driven gear, which in turn drives the transmission rod to rotate, and enables other parts to move in sync, thereby allowing the template support plate to be quickly adjusted to the appropriate support angle.

[0015] Optionally, the linkage mechanism further includes a chuck, a protrusion, and a locking rod. The chuck is coaxially fixed on the drive gear and has a groove at its edge. The protrusion is fixed on the support seat. The locking rod is slidably engaged with the protrusion, and one end of the locking rod abuts against the groove at the edge of the chuck.

[0016] By adopting the above technical solution, the locking rod is used to limit and lock the chuck, thereby achieving the locking effect on the drive gear and preventing the support force on the formwork from changing due to accidental rotation of the drive gear.

[0017] Optionally, a reset member is sleeved on the outside of the locking rod, and a disc structure is provided on the locking rod. The two ends of the reset member abut against the protrusion and the disc structure of the locking rod, respectively.

[0018] By adopting the above technical solution, the elastic force of the reset component is used to push the locking rod, thereby enabling one end of the locking rod to firmly abut against the groove at the edge of the chuck.

[0019] Optionally, one end of the drive gear is connected to a rocker arm, and a regular hexagonal rod is fixed to the mating end of the rocker arm and the drive gear. A regular hexagonal slot is provided at one end of the drive gear, and the regular hexagonal rod of the rocker arm is detachably inserted into the regular hexagonal slot of the drive gear.

[0020] By adopting the above technical solution, the rocker arm is designed to facilitate the operation of the drive gear by construction personnel. At the same time, the plug-in connection structure allows the rocker arm to be removed after use, preventing accidental activation of the drive gear.

[0021] Optionally, the template support plate is provided with an abutment plate at the end that abuts the upright template, and the template support plate is rotatably connected to the center of the abutment plate.

[0022] By adopting the above technical solution, the support area of ​​the diagonal bracing mechanism for the vertical formwork is increased by using the abutment plate, thus avoiding excessive local stress on the vertical formwork and deformation caused by insufficient support area.

[0023] Optionally, a pulley is rotatably connected to one end of the template support plate away from the abutment plate, and after the template support plate slides to a designated position via the pulley, the end of the template support plate near the pulley is locked to the ground by bolts.

[0024] By adopting the above technical solution, the template support plate can be quickly tilted to a predetermined angle by using pulleys, and the template support plate can be locked by bolts, thereby forming a stable support for the opposing template.

[0025] Optionally, the base plate has through holes at both ends, and expansion bolts are installed in the through holes of the base plate, with expansion sleeves fitted around the expansion bolts.

[0026] By adopting the above technical solution, the base plate can be firmly locked by using expansion bolts, preventing it from loosening during support.

[0027] Optionally, a reinforcing plate is obliquely fixed between the fixing plate and the base plate, and together they form a triangular stable structure.

[0028] By adopting the above technical solution, the structural strength between the fixing plate and the base plate is enhanced by using a triangular stabilizing structure.

[0029] Secondly, this application also provides a construction method, comprising the following steps:

[0030] S1. GPS control measurement: When using GPS static measurement, the observed geocentric coordinates should be converted into plane coordinates in the specified coordinate system for the entire survey area. That is, the WGS84 coordinates in the fitting area should be converted into the transformation parameters of the reference coordinate system. The points should be evenly distributed, the structure should be reliable, there should be no obstruction, no electromagnetic interference, no multipath effect, and the baseline observation period should meet the requirements.

[0031] S2. Construction surveying: The surveyor lays out the dimensions, location and top elevation of the reinforced concrete structure according to the design drawings, and nails control stakes and control points to ensure the accuracy of the location, dimensions and elevation. Then, the guide trench is excavated at the corresponding location.

[0032] S3. Erect the formwork. symmetrically erect the formwork on both sides of the guide channel. Use 18mm thick plywood or steel formwork. First, mark the center line, side lines, and axis check line of the formwork. Check the elevation, level the bottom, and select the middle of both sides to install the steel mesh first. Then install the middle formwork, horizontal bars, and diagonal braces, and nail the formwork. Use a plumb bob to straighten the top, pull a line to level it, adjust it into position, and then firmly support and nail it in place.

[0033] S4. Diagonal bracing is fixed at a predetermined distance. At the same time, the linkage rod is inserted between two adjacent transmission rods. Then, the drive gear is rotated to drive the driven gear to rotate, thereby causing the transmission rod to rotate synchronously. This drives the drive plate and the driven plate to move together. Under the limiting action of the limiting plate, the template support plate tilts and abuts against the upright template.

[0034] By adopting the above technical solutions, using S1, S2, S3 and S4 to guide construction operations, controlling the thickness of the retaining wall by setting up the formwork, and forming a support structure through the diagonal bracing mechanism to support the formwork, the deformation and outward tilt of the formwork are effectively prevented. At the same time, by setting up the formwork, the stress on multiple points is made the same, ensuring that the formwork meets the stress requirements and avoiding local deformation of the formwork due to different stresses, which would affect the quality of the retaining wall.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] 1. The rotation of the transmission rod in the diagonal bracing mechanism drives the active plate to rotate, which in turn drives the driven plate to move together, and simultaneously drives the formwork support plate to move together. At the same time, the limiting plate limits the formwork support plate, causing the formwork support plate to deflect and tilt, and then abut against the vertical formwork to form a supporting structure to support the vertical formwork. The thickness of the retaining wall is controlled by the vertical formwork and the outward tilt of the vertical formwork can be effectively prevented.

[0037] 2. By utilizing the linkage mechanism, adjacent transmission rods can move synchronously, thereby driving multiple formwork support plates to move synchronously and support the formwork. This ensures that the formwork is subjected to equal force at multiple points, guaranteeing that the formwork meets the stress requirements and preventing local deformation of the formwork due to uneven stress, which would affect the quality of the retaining wall.

[0045] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0046] This application discloses a retaining wall and its construction method.

[0047] It should be noted that, in the description of this invention, the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "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.

[0048] It should also be noted that the applicant of this application has found in actual engineering projects that retaining walls are crucial in engineering, effectively preventing soil sliding, protecting infrastructure, managing soil erosion, improving land use, and adapting to complex geological conditions. Simultaneously, by resisting lateral pressure, retaining walls ensure soil stability, providing additional safety, especially in extreme conditions such as heavy rainfall or earthquakes. Furthermore, retaining walls can improve land use efficiency, creating more usable space for agriculture and infrastructure construction, making them an indispensable key structure in many civil engineering projects. Therefore, the applicant, combining practical engineering experience, has made this invention.

[0049] Firstly, this application provides a retaining wall:

[0050] Reference Figure 1 and Figure 2A retaining wall and its construction method are disclosed, comprising a guide channel 1, a formwork 2, a bracing mechanism 3, and a linkage mechanism 4. Formwork 2 is symmetrically arranged on both sides of the inner wall of the guide channel 1, and a retaining wall is poured between two adjacent formwork 2. The bracing mechanism 3, used to support the formwork 2, is located on the outer side of the formwork 2. The linkage mechanism 4 is located on the bracing mechanism 3. The bracing mechanism 3 supports the formwork 2, controls the thickness of the retaining wall through the formwork 2, and effectively prevents the formwork 2 from tilting outward. Simultaneously, the linkage mechanism 4 enables two adjacent bracing mechanisms 3 to move synchronously, thereby driving multiple formwork support plates 34 to move synchronously and support the formwork 2. This ensures that the formwork 2 experiences equal stress at multiple points, meets the stress requirements, and prevents local deformation of the formwork 2 due to uneven stress, which could affect the quality of the retaining wall.

[0051] Specifically, the diagonal bracing mechanism 3 includes a fixed plate 31, a base plate 32, a limiting plate 33, a template support plate 34, a transmission rod 35, an active plate 36, and a driven plate 37. The fixed plate 31 is vertically fixed at the top center of the base plate 32. One end of the limiting plate 33 is rotatably connected to the side wall of the fixed plate 31, and the other end is rotatably connected to the template support plate 34. The transmission rod 35 is rotatably connected to the top of the fixed plate 31. One end of the active plate 36 is fixed to the transmission rod 35. The two ends of the driven plate 37 are rotatably connected to the template support plate 34 and the end of the active plate 36 away from the transmission rod 35, respectively. The limiting plate 33 and the driven plate 37 are staggered and cross-arranged.

[0052] In this embodiment of the application, the linkage mechanism 4 includes a linkage rod 41, a support seat 42, a driving gear 43, and a driven gear 44. The rotation of the driving gear 43 drives the driven gear 44 to mesh and link, which in turn drives the transmission rod 35 to rotate. The linkage rod 41 enables two adjacent transmission rods 35 to move synchronously, thereby enabling other parts to move synchronously and allowing multiple template support plates 34 to be adjusted to the appropriate support angle synchronously and quickly.

[0053] Reference Figure 3 and Figure 4 Both ends of the transmission rod 35 have concave polygonal slots at their shaft centers. The linkage rod 41 has a polygonal structure and is inserted into the polygonal slots of two adjacent transmission rods 35. The support seat 42 is fixed to the top of the side wall of the fixing plate 31. The driving gear 43 is rotatably connected to the support seat 42. The driven gear 44 is coaxially fixed to the transmission rod 35 and meshes with the driving gear 43.

[0054] Reference Figure 5In this embodiment, the linkage mechanism 4 also includes a chuck 45, a protrusion 46, a locking rod 47, and a reset member 48. The locking rod 47 is used to limit and lock the chuck 45, thereby achieving a locking effect on the drive gear 43 and preventing the support force on the template 2 from changing due to accidental rotation of the drive gear 43.

[0055] The chuck 45 is coaxially fixed on the drive gear 43, and a groove is provided on the edge of the chuck 45. The protrusion 46 is fixed on the support 42. The locking rod 47 is slidably engaged with the protrusion 46, and one end of the locking rod 47 abuts in the groove on the edge of the chuck 45. A reset member 48 is sleeved on the outside of the locking rod 47, and a disc structure is provided on the locking rod 47. The two ends of the reset member 48 abut against the protrusion 46 and the disc structure of the locking rod 47, respectively.

[0056] Specifically, in this embodiment, regarding the drive gear 43, one end of the drive gear 43 is connected to a rocker arm 49. A regular hexagonal rod is fixed to the mating end of the rocker arm 49 and the drive gear 43, and a regular hexagonal slot is provided at one end of the drive gear 43. The regular hexagonal rod of the rocker arm 49 is detachably inserted into the regular hexagonal slot of the drive gear 43. The rocker arm 49 facilitates the operation of the drive gear 43 by construction personnel, and at the same time, the plug-in connection structure allows the rocker arm 49 to be removed after use, avoiding accidental activation of the drive gear 43.

[0057] In this embodiment, an abutment plate 38 is provided on the end of the template support plate 34 that abuts against the upright template 2, and the template support plate 34 is rotatably connected to the center of the abutment plate 38. A pulley 39 is rotatably connected to the end of the template support plate 34 away from the abutment plate 38. After the template support plate 34 slides to the designated position via the pulley 39, the end of the template support plate 34 near the pulley 39 is locked to the ground by bolts. The abutment plate 38 increases the support area of ​​the inclined bracing mechanism 3 for the upright template 2, avoiding excessive local stress on the upright template 2 due to insufficient support area and deformation. At the same time, the pulley 39 enables the template support plate 34 to quickly tilt to a predetermined angle, and the template support plate 34 is locked by bolts, thereby forming a stable support for the upright template 2.

[0058] Through holes are provided at both ends of the base plate 32, and expansion bolts 5 are provided in the through holes of the base plate 32. Expansion sleeves are fitted on the outside of the expansion bolts 5. Reinforcing plates are fixed at an angle between the fixing plate 31 and the base plate 32, and together they form a triangular stable structure. The installation of expansion bolts 5 can make the base plate 32 firmly locked to prevent it from loosening when supported, and the structural strength between the fixing plate 31 and the base plate 32 is enhanced by the triangular stable structure.

[0059] The implementation principle of a retaining wall and its construction method in this application embodiment is as follows: First, the formwork 2 is placed inside the guide groove 1. Then, the base plate 32 is fixed in the predetermined position by the expansion bolts 5. The linkage rod 41 is inserted between two adjacent transmission rods 35. Then, the drive gear 43 is rotated by the rocker arm 49, which drives the driven gear 44 to mesh and link. At this time, the transmission rod 35 rotates and drives the drive plate 36 to rotate. Then, the drive plate 36 drives the driven plate 37 to link and simultaneously drives the formwork support plate 34 to link. At the same time, the formwork support plate 34 is limited by the limiting plate 33, so that the formwork support plate 34 deflects and tilts, and then abuts against the formwork 2 to form a support structure to support the formwork 2. Then, the bottom end of the formwork support plate 34 is connected and locked to the ground by bolts. Then, the retaining wall is poured between two adjacent formworks 2.

[0060] Secondly, referring to Figures 1-5 This application also provides a construction method, comprising the following steps:

[0061] S1. GPS control measurement: When using GPS static measurement, the observed geocentric coordinates should be converted into plane coordinates in the specified coordinate system for the entire survey area. That is, the WGS84 coordinates in the fitting area should be converted into the transformation parameters of the reference coordinate system. The points should be evenly distributed, the structure should be reliable, there should be no obstruction, no electromagnetic interference, no multipath effect, and the baseline observation period should meet the requirements.

[0062] S2. Construction surveying: The surveyor lays out the dimensions, location and top elevation of the reinforced concrete structure according to the design drawings, and nails control stakes and control points to ensure the accuracy of the location, dimensions and elevation. Then, the guide trench is excavated at the corresponding location.

[0063] S3. Erect the formwork. Erect the formwork 2 symmetrically on both sides of the guide channel 1. The formwork 2 is made of 18mm thick plywood or steel formwork. First, mark the center line, two side lines and axis check line of the formwork, check the elevation, level the bottom, select the middle of both sides to install the steel mesh first, and then install the middle formwork, horizontal bar and diagonal brace, and nail the formwork; use a plumb bob to straighten the top, pull the line to level, adjust and position it, and then support and nail it firmly.

[0064] S4. Diagonal bracing is fixed. Multiple diagonal bracing mechanisms 3 are fixed at predetermined positions at equal intervals. At the same time, the linkage rod 41 is inserted between two adjacent transmission rods 35. Then, the drive gear 43 is rotated to drive the driven gear 44 to move together, thereby causing the transmission rods 35 to rotate synchronously. This drives the drive plate 36 and the driven plate 37 to move together. Under the limiting action of the limiting plate 33, the template support plate 34 tilts and abuts against the upright template 2.

[0065] By adopting the above technical solution, using S1, S2, S3 and S4 to guide the construction operation, controlling the thickness of the retaining wall by setting the formwork 2, and supporting the formwork 2 by forming a support structure through the diagonal bracing mechanism 3, the formwork 2 is effectively prevented from deforming and tilting outward. At the same time, by setting the formwork 2 so that multiple points of the formwork 2 are subjected to the same force, the formwork 2 is guaranteed to meet the stress requirements and avoids local deformation of the formwork 2 due to different stress, which would affect the quality of the retaining wall.

[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
