Description

Technical Field

[0001] The present invention relates to the technical field of side ditch construction, and in particular to an adjustable modular side ditch formwork and a side ditch construction method. Background Art

[0002] A side ditch refers to a water channel set on both sides of a roadbed to collect and drain the flowing water on the road surface, road shoulder and slope. It is generally made of concrete. Most of the cross-sectional shapes of the drainage troughs are U-shaped, and are divided into open ditches and closed ditches. Since the closed ditch has better safety, it has been well applied in engineering.

[0003] For a side ditch in the form of a closed ditch, a cover plate needs to be installed above the drainage trough. Therefore, in order to ensure that the cover plate is flush with the ground, the cross-section of the groove of this type of side ditch is trapezoidal, which includes a shoulder flush with the ground, a groove side supporting the cover plate, and a drainage trough in the middle. Due to its relatively complex structure, during construction, the traditional method is to manually erect the outer formwork, inner formwork, groove side formwork, and groove side formwork respectively, and fix and connect the formworks through supports. It is also necessary to ensure the sealing effect of the joints between the formworks. Then, elevation lines are drawn on the outer formwork according to the side ditch dimensions, and then concrete is poured. After curing, all the formworks are removed. It can be seen that the traditional manual support of various forms of formworks has a large amount of work, low construction efficiency, difficult to ensure the sealing between the formworks, and the dimensions of each formwork are only customized for a side ditch of a single specification or size, and it is difficult to be universal for side ditches of different sizes, which brings many inconveniences to the side ditch construction project. Summary of the Invention

[0004] Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by the present invention is: to provide an adjustable modular side ditch formwork and a side ditch construction method, which solve the problems of low construction efficiency, poor sealing effect, poor integrity, difficult adjustment, and poor universality in the prior art.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] An adjustable modular side ditch formwork includes a support plate and two vertically and oppositely arranged groove side formworks, and both ends of the support plate are respectively connected to the tops of the two groove side formworks;

[0007] Between the two side formworks of the trench, there are symmetrically arranged two elevation adjustment plates, two side formworks of the trench, and two groove formworks parallel to the side formworks of the trench. The two end faces of the elevation adjustment plates, side formworks of the trench, and groove formworks in the length direction are flush with the two end faces of the side formworks of the trench respectively; among them, the groove formwork includes an inner sleeve plate and an outer sleeve plate arranged vertically. The outer sleeve plate is slidably fitted and attached to the outside of the inner sleeve plate, and a bottom formwork is movably installed between the lower ends of the two inner sleeve plates; the cross-section of the side formwork of the trench is L-shaped, its vertical section is slidably fitted and attached to the inside of the elevation adjustment plate, and its horizontal section is slidably fitted and attached to the upper end of the outer sleeve plate.

[0008] The elevation adjustment plate, side formwork of the trench, and inner sleeve plate are respectively connected to the support plate through a first adjustment mechanism, a second adjustment mechanism, and a third adjustment mechanism. The first adjustment mechanism, second adjustment mechanism, and third adjustment mechanism can respectively drive the elevation adjustment plate, side formwork of the trench, and groove formwork to move vertically, or move in a direction close to or away from the side formwork of the trench.

[0009] As an optimization, the first adjustment mechanism includes a first slider slidably fitted and installed on the support plate. A first screw hole is opened on the first slider, and a first adjustment bolt is threadedly fitted and installed in the first screw hole. The screw rod of the first adjustment bolt passes through the first screw hole and is rotatably installed on the elevation adjustment plate.

[0010] As an optimization, the second adjustment mechanism includes a second slider slidably fitted and installed on the support plate. A second screw hole is opened on the second slider, and a second adjustment bolt is threadedly fitted and installed in the second screw hole. The screw rod of the second adjustment bolt passes through the second screw hole and is rotatably installed on the side formwork of the trench.

[0011] As an optimization, the third adjustment mechanism includes a transmission screw rod. The transmission screw rod is installed in a transmission box, and its two ends extend out of the transmission box and are respectively threadedly fitted and connected to the two inner sleeve plates. When the transmission screw rod rotates, it can drive the two inner sleeve plates to move away from or close to each other synchronously;

[0012] It also includes an outer adjustment rod and an inner adjustment rod sleeved coaxially. One end of the outer adjustment rod is threadedly fitted and connected to the support plate, and the other end is rotatably connected to the transmission box. One end of the inner adjustment rod extends out of the outer adjustment rod, and the other end extends into the transmission box and is connected to the transmission screw rod through a transmission component, and can drive the transmission screw rod to rotate.

[0013] As an optimization, the transmission component includes a first bevel gear coaxially sleeved on the inner adjustment rod and a second bevel gear coaxially sleeved on the transmission screw rod and meshed with the first bevel gear. Among them, the rotation axes of the first bevel gear and the second bevel gear are perpendicular to each other.

[0014] As an optimization, the inner lining plate is of a box structure, and a sliding hole is formed in the lower end of its side wall along its length direction. The end of the bottom formwork is slidably connected with the sliding hole and extends into the inner lining plate for a certain distance after passing through the sliding hole.

[0015] As an optimization, docking flanges are provided at both ends of the gutter side formwork along its length direction for docking with adjacent gutter side formworks.

[0016] As an optimization, at least two support plates are distributed along the length direction of the gutter side formwork, and lifting rings are provided at positions near both ends on the upper side of the support plates.

[0017] Based on the above gutter formwork, the present invention also provides a gutter construction method, which uses the adjustable modular gutter formwork described above and includes the following steps.

[0018] Determine the gutter size and excavate the foundation trench;

[0019] Respectively adjust the elevation adjustment plate, the gutter wall formwork and the groove formwork to positions corresponding to the gutter size through the first adjustment mechanism, the second adjustment mechanism and the third adjustment mechanism;

[0020] Lift the gutter formwork into the foundation trench and connect the adjacent gutter formworks in series along the length direction of the gutter side formwork to complete the assembly of the gutter formwork;

[0021] Pour concrete from the space between the elevation adjustment plate and the gutter side formwork until the upper end surface of the concrete is flush with the lower end of the elevation adjustment plate;

[0022] After curing, disconnect the connection between the adjacent gutter formworks and sequentially complete the demoulding by lifting the gutter formwork as a whole to complete the gutter construction.

[0023] The present application has the following beneficial effects compared with the prior art:

[0024] The present invention adopts an integral and modular gutter formwork, and the elevation adjustment plate, the gutter wall formwork, the groove formwork and the gutter side formwork inside the gutter are all adjustable. It can realize the pouring of gutters with various sizes such as different gutter shoulder heights and widths, different gutter wall heights and widths, different groove widths and depths according to the gutter size. And the formworks are connected by splicing, which can quickly form the gutter formwork. After pouring and curing, it is convenient to demould as a whole, greatly improving the construction efficiency. At the same time, each formwork does not need to be disassembled and assembled separately, which well guarantees the sealing effect and is not easy to leak slurry during pouring. Therefore, the modular integral gutter formwork of the present invention can be freely adjusted according to size requirements, has good versatility, high construction efficiency and good sealing effect.

Specific embodiments

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] During specific implementation: Refer to Figures 1-4 ,

[0032] An adjustable modular side trench formwork includes a support plate 1 and two vertically and oppositely arranged side formworks 2 of the trench. The two ends of the support plate 1 are respectively connected to the tops of the two side formworks 2 of the trench. Specifically, the side formwork 2 of the trench can be slidably and cooperatively connected to the support plate 1, so as to realize the adjustment of the side formwork 2 of the trench. Specifically, the sliding cooperation method can adopt the existing cooperation method of a chute and a slider, and be fixed through structures such as locking bolts for easy adjustment.

[0033] Symmetrically arranged between the two side formworks 2 of the trench are two elevation adjustment plates 3, two side formworks 4 of the trench bank and two trench formworks parallel to the side formworks 2 of the trench. The two end faces of the elevation adjustment plate 3, the side formwork 4 of the trench bank and the trench formwork along the length direction are respectively flush with the two end faces of the side formwork 2 of the trench. Docking flanges 14 are provided at both ends of the side formwork 2 of the trench along its length direction for docking with the adjacent side formwork 2 of the trench. In order to improve the sealing effect, sealing gaskets can be provided on the front and rear end faces of the side formwork 2 of the trench, the elevation adjustment plate 3, the side formwork 4 of the trench bank and the trench formwork. The side formwork 2 of the trench is connected through the docking flange 14, while the internal elevation adjustment plate 3, the side formwork 4 of the trench bank and the trench formwork only rely on mutual fitting. Of course, the cooperation method of a pin and a pin hole can also be adopted to realize the docking of the internal formworks.

[0034] Among them, the groove formwork includes an inner sleeve plate 5 and an outer sleeve plate 6 arranged vertically. The outer sleeve plate 6 is slidably fitted and attached to the outside of the inner sleeve plate 5, and a bottom formwork 7 is movably installed between the lower ends of the two inner sleeve plates 5. Specifically, the cross-section of the outer sleeve plate 6 is L-shaped, its vertical section is slidably connected to the inner sleeve plate 5, and a bevel is provided at its lower end, which is inclined downward from top to bottom towards the direction close to the inner sleeve plate 5. In this way, a trumpet-shaped bonding surface is formed after the concrete is poured, which is beneficial to demoulding. The inner sleeve plate 5 is a box structure, and sliding holes are opened along the length direction at the lower end of its side wall. The end of the bottom formwork 7 is slidably connected to the sliding hole and extends into the inner sleeve plate 5 for a certain distance after passing through the sliding hole. In this way, when the two inner sleeve plates 5 move away from or close to each other, the bottom formwork 7 can slide along the sliding hole, and the part extending into the inner sleeve plate 5 can compensate for the distance change between the two inner sleeve plates 5, so that the joint position between the bottom formwork 7 and the inner sleeve plate 5 always remains in a sealed state. Specifically, a sealing gasket is provided around the inner wall of the sliding hole for one week to ensure sealing, and a limiting structure is provided at the end of the bottom formwork 7 extending into the inner sleeve plate 5 to prevent the bottom formwork 7 from being completely pulled out of the inner sleeve plate 5. At the same time, since the sliding hole is arranged along the entire length of the inner sleeve plate 5, a plurality of upwardly concave limiting grooves can be provided on the upper side wall of the sliding hole. Correspondingly, limiting strips slidably matched with the limiting grooves are provided on the bottom formwork 7 to prevent the bottom formwork 7 from moving back and forth, improving the stability and sealing effect.

[0035] The cross-section of the groove side formwork 4 is L-shaped, its vertical section is slidably fitted and attached to the inside of the elevation adjustment plate 3, and its horizontal section is slidably fitted and attached to the upper end of the horizontal section of the outer sleeve plate 6. In this way, a groove shoulder is formed between the vertical section of the groove side formwork 4 and the groove side formwork 2, and its height is controlled by the elevation adjustment plate 3. A groove side is formed below the horizontal section of the groove side formwork 4, and its width and height are controlled by the horizontal and vertical movement of the groove side formwork 4. The up and down movement of the inner sleeve plate 5 can control the depth of the groove, and the horizontal movement can control the width of the groove, so as to realize the overall adjustability of the side ditch formwork.

[0036] Specifically, the elevation adjustment plate 3, the groove side formwork 4 and the inner sleeve plate 5 are respectively connected to the support plate 1 through a first adjustment mechanism, a second adjustment mechanism and a third adjustment mechanism. The first adjustment mechanism, the second adjustment mechanism and the third adjustment mechanism can respectively drive the elevation adjustment plate 3, the groove side formwork 4 and the groove formwork to move vertically, or move in the direction close to or away from the groove side formwork 2.

[0037] The first adjustment mechanism includes a first slider slidably fitted and mounted on the support plate 1. A first threaded hole is provided in the first slider, and a first adjustment bolt 8 is threadedly fitted and mounted in the first threaded hole. The screw rod of the first adjustment bolt 8 passes through the first threaded hole and is rotatably mounted on the elevation adjustment plate 3. Specifically, the first slider is slidably fitted and clamped in the slideway on the support plate 1 to restrict its up-and-down movement. By rotating the first adjustment bolt 8, the first adjustment bolt 8 moves up and down, thereby driving the elevation adjustment plate 3 to move up and down, so as to adjust the elevation position of its lower end. In order to facilitate observation and demolding, a slope inclined from top to bottom and approaching the rib formwork 4 is provided at the lower end of the elevation adjustment plate 3. At the same time, generally, the elevation adjustment plate 3 is in close connection with the rib formwork 4. Specifically, existing forms such as chutes and slide bars can be adopted to keep the elevation adjustment plate 3 and the rib formwork 4 always in close contact. Therefore, the purpose of setting the first slider is to drive the rib formwork 4 to move horizontally by pushing the first adjustment bolt 8, or to drive the elevation adjustment plate 3 to move horizontally when the rib formwork 4 moves horizontally, so as to ensure its integrity. The above-mentioned sliding structures are all relatively conventional existing technologies and will not be elaborated here, nor are they shown in the drawings.

[0038] The second adjustment mechanism includes a second slider slidably fitted and mounted on the support plate. A second threaded hole is provided in the second slider, and a second adjustment bolt 9 is threadedly fitted and mounted in the second threaded hole. The screw rod of the second adjustment bolt 9 passes through the second threaded hole and is rotatably mounted on the rib formwork 4. Its specific installation method is the same as that of the first adjustment mechanism and will not be elaborated.

[0039] The third adjustment mechanism includes a transmission screw rod 10. The transmission screw rod 10 is installed in a transmission box 11, and its two ends extend out of the transmission box 11 and are respectively threadedly fitted and connected with two inner sleeve plates 5. When the transmission screw rod 10 rotates, it can drive the two inner sleeve plates 5 to move away from or close to each other synchronously.

[0040] It also includes an outer adjustment rod 12 and an inner adjustment rod 13 sleeved coaxially. One end of the outer adjustment rod 12 is threadedly fitted and connected with the support plate 1, and the other end is rotatably connected with the transmission box 11. One end of the inner adjustment rod 13 extends out of the outer adjustment rod 12, and the other end extends into the transmission box 11 and is connected with the transmission screw rod 10 through a transmission component and can drive the transmission screw rod 10 to rotate. The transmission component includes a first bevel gear coaxially sleeved on the inner adjustment rod 13 and a second bevel gear coaxially sleeved on the transmission screw rod 10 and meshing with the first bevel gear. Among them, the rotation axes of the first bevel gear and the second bevel gear are perpendicular to each other.

[0041] In use, by rotating the inner adjusting rod 13, the inner adjusting rod 13 drives the horizontally arranged transmission screw rod 10 to rotate through the transmission of the first bevel gear and the second bevel gear at a 90° angle, thereby driving the two inner sleeve plates 5 that are in threaded fit connection with it to move away from or close to each other synchronously, so as to realize the adjustment of the groove width. When rotating the outer adjusting rod 12, the outer adjusting rod 12 is in threaded fit connection with the support plate 1. Therefore, the outer adjusting rod 12 can drive the transmission box 11 to move vertically, thereby driving the two inner sleeve plates 5 to move vertically through the transmission screw rod 10, so that the inner sleeve plates 5 slide along the outer sleeve plates 6 to realize the adjustment of the groove depth.

[0042] At least two support plates 1 are distributed along the length direction of the side ditch formwork 2, and lifting rings 15 are arranged at positions near both ends on the upper side of the support plate 1. In this way, it is convenient for the overall hoisting of the side ditch formwork.

[0043] Based on the above side ditch formwork, the present invention also provides a side ditch construction method, which adopts the adjustable modular side ditch formwork described above, and includes the following steps.

[0044] Determine the side ditch dimensions and excavate the foundation trench, and the side ditch dimensions include the dimensions of the ditch shoulder, ditch wall, and groove.

[0045] Adjust the elevation adjustment plate 3, ditch wall formwork 4, and groove formwork to positions corresponding to the side ditch dimensions respectively through the first adjustment mechanism, second adjustment mechanism, and third adjustment mechanism.

[0046] Lift the side ditch formwork into the foundation trench, and connect the adjacent side ditch formworks in butt joint along the length direction of the side ditch formwork 2 to complete the assembly of the side ditch formwork.

[0047] Pour concrete from the spacing between the elevation adjustment plate 3 and the side ditch formwork 2 until the upper end surface of the concrete is flush with the lower end of the elevation adjustment plate 3.

[0048] After the curing is completed, disconnect the connection between the adjacent side ditch formworks, and sequentially complete the demoulding by hoisting the side ditch formwork as a whole to complete the side ditch construction.

[0049] The present invention adopts an integral and modular side ditch formwork, and the elevation adjustment plate, ditch wall formwork, groove formwork, and side ditch formwork inside the side ditch are all adjustable. It can realize the pouring of side ditches with various dimensions such as different ditch shoulder heights and widths, different ditch wall heights and widths, different groove widths and depths according to the side ditch dimensions. And the formworks are connected by splicing, which can quickly form the side ditch formwork. After pouring and curing, it is convenient for overall demoulding, greatly improving the construction efficiency. At the same time, each formwork does not need to be disassembled and assembled separately, which well guarantees the sealing effect and is not easy to leak slurry during pouring. Therefore, the modular integral side ditch formwork of the present invention can be freely adjusted according to size requirements, has good versatility, high construction efficiency, and good sealing effect.
