Description

Technical Field

[0001] The present application relates to the technical field of pipeline construction support, and in particular to an assembled support structure for a trench. Background Art

[0002] Pipeline construction typically requires trench excavation for pipeline laying. To prevent foundation pit collapse, trench excavation requires slope and support measures based on geological conditions, excavation depth, surrounding environment, underground pipelines, groundwater, and other factors. Trench support refers to the support, reinforcement, and protection measures taken on the trench sidewalls and surrounding environment to ensure the safety of underground structure construction and the trench surrounding environment. Trench support is required during pipeline construction.

[0003] A common existing support structure is to weld a support rod of a specific length between two support plates according to the width and structure of the groove, and use the support rod to limit the distance between the two support plates, thereby using the two support plates to support the groove.

[0004] However, the aforementioned support structure requires support rods and plates of varying lengths to support trenches of varying sizes, and welding is time-consuming, making construction inconvenient. Furthermore, due to the typically large length of trenches, the overall construction workload of the aforementioned support structure is also substantial. As trench length increases, the construction period and costs increase. Summary of the Invention

[0005] The present application provides an assembled support structure for trenches, which can be applied to trenches of different specifications and sizes, and can reduce construction difficulty, shorten construction period and reduce construction costs.

[0006] This application provides a prefabricated support structure for a trench, which adopts the following technical solutions:

[0008] By adopting the above technical solution, after the supporting structure hoist is inserted into the trench, the two bottom plates abut against the bottom wall of the trench, and a rotating rod is controlled to rotate to drive the two side plates toward the corresponding trench side walls until they abut against each other, so that the supporting structure can be applied to trenches of different specifications and sizes, and the construction operation process of the supporting structure supporting the trench can be simpler and more convenient, thereby reducing the construction difficulty, shortening the construction period and reducing the construction cost.

[0009] Optionally, a plurality of positioning pins are further included, and the plurality of positioning pins are respectively arranged on the two base plates, the positioning pins are movably connected to the base plates, and the movable direction of the positioning pins is perpendicular to the base plates.

[0010] By adopting the above technical solution, after the positioning nails are movably penetrated into the soil layer below the base plate, the position stability of the support structure relative to the trench can be improved, and at the same time, the support strength of the support structure can be improved, thereby improving the support effect on the trench.

[0011] Optionally, multiple movable components are also included, and the movable components include a frame and a roller. The frame is movably connected to the base plate, and the movable direction of the frame is perpendicular to the base plate; the roller is universally connected to the frame, and the roller is arranged at one end of the frame close to the bottom wall of the groove.

[0012] By adopting the above technical solution, after the supporting structure is hoisted into the trench, the control frame is moved to make the roller contact the bottom wall of the trench, which can facilitate the position adjustment of the supporting structure in the trench. At the same time, it can reduce the friction between the bottom plate and the bottom wall of the trench during the process of rotating the control rod to drive the two side plates to move, thereby making the construction operation process of the supporting structure supporting the trench more convenient and labor-saving.

[0014] By adopting the above technical solution, the movement of the positioning pins and the movement of the frame are controlled by the control component.

[0023] Optionally, it further includes a plurality of limiting members for limiting the distance between the plurality of auxiliary plates above the same side plate, and the limiting members are simultaneously mounted on the corresponding plurality of rotating rods.

[0024] By adopting the above technical solution, the limiting parts can keep the two corresponding auxiliary plates above the two side plates at the same horizontal height, and can also maintain the spacing between the multiple auxiliary plates above one side plate, thereby improving the support strength of the multiple auxiliary plates and the elastic plates. At the same time, it can make the support effect of the auxiliary plates on both sides of the groove walls more even, thereby improving the overall support effect of the support structure on the groove.

[0025] Optionally, one side of the side plate and one side of the auxiliary plate both have concave-convex patterns, and the concave-convex patterns abut against the side walls of the groove.

[0043] The following is combined with Figure 1-9 This application is described in further detail.

[0044] Example 1:

[0045] Reference Figure 1 and Figure 2The embodiment of the present application discloses an assembled support structure for a trench 101, which is suitable for supporting a trench 101 with an overall rectangular cross-section. During the laying of the pipeline 102, multiple sections of the pipeline 102 are sequentially hoisted into the trench 101 to complete the splicing construction. During the splicing construction process after each section of the pipeline 102 is hoisted, the support structure supports the trench 101 at the position in the trench 101 for the construction of the section of the pipeline 102. After the splicing construction of the section of the pipeline 102 is completed, the support structure is hoisted and moved to the position in the trench 101 for the construction of the next section of the pipeline 102 to support the trench 101. Then, the next section of the pipeline 102 is hoisted into the trench 101 for splicing construction, and the cycle continues.

[0046] The support structure includes two support bases 1 and a support mechanism 2. The support mechanism 2 includes multiple first support assemblies 21 and several linkage assemblies 23. The support bases 1 are used to abut against the groove walls of the groove 101. The first support assemblies 21 are used to support the support bases 1 so that they can support the groove 101. The linkage assemblies 23 are used to facilitate construction personnel to adjust the multiple first support assemblies 21. In this embodiment, the support structure preferably includes four first support assemblies 21 and one linkage assembly 23. In other embodiments, the number of first support assemblies 21 and linkage assemblies 23 can be adjusted according to specific usage.

[0047] The support base 1 is a plate-like structure with an L-shaped cross-section. The support base 1 includes a side plate 11 for abutting against the side walls of the groove 101 and a bottom plate 12 for abutting against the bottom wall of the groove 101. One end of the side plate 11 in the width direction is fixedly connected to one end of the bottom plate 12 in the width direction, and the side plate 11 and the bottom plate 12 are perpendicular to each other. In this embodiment, the support base 1 is preferably made of steel, and the size of the side plate 11 is preferably adapted to the size of the side walls of the groove 101, that is, the width of the side plate 11 is equal to the depth of the groove 101. In other embodiments, the width of the side plate 11 may also be greater than the depth of the groove 101.

[0048] Furthermore, the support base 1 preferably has a plurality of lifting ears 103 on the side of the side panel 11 away from the bottom panel 12 to facilitate the lifting of the support base 1. Preferably, there are two lifting ears 103 on the side panel 11, and the two lifting ears 103 are respectively located at the ends of the length direction of the side panel 11. In this embodiment, the lifting ears 103 are preferably fixedly connected to the side panel 11 by welding; in other embodiments, the lifting ears 103 can also be detachably connected to the side panel 11 by threading; and since the lifting ears 103 are common in the prior art, they will not be described in detail here.

[0049] The two support bases 1 are located on either side of the groove 101, and the first support assembly 21 is installed between the two support bases 1 in a state perpendicular to the side panels 11. The four first support assemblies 21 are located in pairs between the two ends of the support base 1 in the longitudinal direction. The two first support assemblies 21 at the same end are located in the same vertical plane, and the corresponding two first support assemblies 21 at the two ends are located in the same horizontal plane.

[0050] In this embodiment, the distance between the two first support components 21 located in the same horizontal plane at both ends is preferably greater than the length dimension of the single section of pipe 102. When the support seat 1 supports the groove 101, the distance between the two side plates 11 is greater than the radial dimension of the single section of pipe 102, and the distance between the first support component 21 closer to the bottom plate 12 and the end face of the bottom plate 12 that abuts against the bottom wall of the groove 101 is greater than the radial dimension of the single section of pipe 102.

[0051] When the support structure plays a supporting role on the trench 101, a single section of pipe 102 can be hoisted from the space between the two first support components 21 located in the same horizontal plane at both ends and placed into the trench 101. After the section of pipe 102 is spliced ​​with the previous section of pipe 102, the support structure can be hoisted out of the trench 101 without being restricted by the pipe 102.

[0052] The first support assembly 21 includes a rotating rod 211 and a movable rod 212. Preferably, the rotating rod 211 and the movable rod 212 are both cylindrical rod-shaped structures. One end of the rotating rod 211 in the axial direction is rotatably connected to one side plate 11, and the rotating axis of the rotating rod 211 is perpendicular to the side plate 11 and coincides with its own axis; one end of the movable rod 212 in the axial direction is fixedly connected to the other side plate 11, and the axis of the movable rod 212 is perpendicular to the side plate 11 and coincides with the rotating axis of the corresponding rotating rod 211; the other end of the rotating rod 211 in the axial direction is sleeved on the other end of the movable rod 212 in the axial direction, and the rotating rod 211 and the movable rod 212 are threadedly engaged. By controlling the rotation of the rotating rod 211, the movable rod 212 can be driven to move along the axial direction relative to the rotating rod 211, thereby changing the spacing between the two side plates 11, and thereby enabling the two side plates 11 to adapt to the specifications of the groove 101 and respectively abut against the two side walls of the groove 101.

[0053] The linkage assembly 23 includes multiple gears 231 and a chain 232. The multiple gears 231 correspond one-to-one with the multiple first support assemblies 21. In this embodiment, the linkage assembly 23 preferably includes four gears 231. The four gears 231 are respectively mounted and fixed on the four rotating rods 211, and the axes of the gears 231 coincide with the rotation axes of the corresponding rotating rods 211. In this embodiment, the gears 231 are preferably mounted on the end of the rotating rod 211 away from the movable rod 212.

[0054] The chain 232 is simultaneously wound around the four gears 231 and meshes with the four gears 231 one by one. By controlling the rotation of one rotating rod 211, the gear 231 on the rotating rod 211 can drive the chain 232 to move. The movement of the chain 232 can drive the remaining rotating rods 211 to rotate synchronously in the same direction through the remaining gears 231, thereby making it convenient for construction workers to adjust the four first support assemblies 21 at the same time.

[0055] In this embodiment, for ease of display, the four gears 231 and the chain 232 are directly exposed. In other embodiments, a protective cover for protecting the linkage assembly 23 may also be fixedly installed on the side panel 11 adjacent to the linkage assembly 23.

[0056] The support structure also includes a plurality of positioning pins 3. The support base 1 has a plurality of through-holes 121 extending perpendicularly to the base 12. The through-holes 121 on the same base 12 are evenly spaced along the length of the base 12, and the diameters of the through-holes 121 match the radial dimensions of the positioning pins 3. In this embodiment, the positioning pins 3 are preferably used in a sliding connection with the base 12.

[0057] When the support base 1 supports the trench 101, the tail of the positioning pin 3 is passed through the through hole 121 and then into the soil layer at the bottom of the trench 101, and the head of the positioning pin 3 is abutted against the bottom plate 12. At this time, multiple positioning pins 3 together fix the relative position of the bottom plate 12 and the trench 101, thereby improving the support strength of the support base 1 for the trench 101, and further improving the support effect of the overall support structure for the trench 101.

[0058] The implementation principle of the assembled support structure for the trench 101 in the embodiment of the present application is as follows:

[0059] After the supporting structure is hoisted into the trench 101 through the lifting lugs 103, the bottom plates 12 of the two supporting seats 1 are both against the bottom wall of the trench 101; then a first support assembly 21 is adjusted to control a rotating rod 211 to rotate, and a plurality of rotating rods 211 are driven to rotate synchronously in the same direction through the linkage assembly 23, thereby driving the movable rod 212 to move relative to the corresponding rotating rod 211 until the side plates 11 of the two supporting seats 1 are respectively against the two side walls of the trench 101 and play a supporting role; then a plurality of positioning nails 3 are passed through the corresponding through-holes 121 one by one into the soil layer at the bottom of the trench 101, so that the position of the supporting seat 1 relative to the trench 101 is fixed, thereby improving the supporting effect of the supporting structure on the trench 101.

[0060] Example 2:

[0061] Reference Figure 1 and Figure 3The difference between this embodiment and embodiment 1 is that the support structure also includes a plurality of movable components 4 for facilitating the position adjustment of the support structure in the groove 101 and two control components 5 for facilitating the use of the movable components 4 and the positioning pins 3.

[0062] Reference Figure 3 and Figure 4 , multiple moving components 4 are respectively installed on the base plates 12 of the two supporting seats 1. Preferably, the number of moving components 4 installed on the two base plates 12 is equal, and the installation positions of the multiple moving components 4 on the two base plates 12 are symmetrically distributed.

[0063] Reference Figure 4 and Figure 5 The movable assembly 4 includes a frame 41 and a roller 42. The frame 41 is movably connected to the base plate 12, and the movable direction of the frame 41 is perpendicular to the base plate 12. The roller 42 is mounted on the bottom of the frame 41 and is universally connected to the frame 41. During the movement of the frame 41, the frame 41 drives the roller 42 to move in and out of the bottom of the base plate 12. In this embodiment, since the universal connection between the roller 42 and the frame 41 is common in the prior art, it will not be described in detail here, and only a brief description is shown in the drawings.

[0064] In this embodiment, it is preferred that multiple movable components 4 correspond one-to-one to multiple through-holes 121 on the same base plate 12, and the multiple movable components 4 are respectively located on the same side of the corresponding through-holes 121; and it is preferred that the frame 41 and the positioning pins 3 are both installed on the base plate 12 in a sliding connection manner.

[0065] In this embodiment, two control components 5 are respectively installed on the two base plates 12 to control the sliding of the multiple frames 41 and the positioning pins 3 installed on the base plates 12 .

[0066] Reference Figure 5 and Figure 6 The control assembly 5 includes an active rod 51, a driven rod 52, a plurality of transmission gears 53, a plurality of turbines 54 and a plurality of worm gears 55. Preferably, the active rod 51 and the driven rod 52 are both cylindrical rod-shaped structures, one end of the active rod 51 penetrates into the interior of the base plate 12 in a direction parallel to the length direction of the base plate 12, and the other end of the active rod 51 is exposed on one side of the base plate 12, which is convenient for construction workers to control; the driven rod 52 is installed inside the base plate 12 and is located on one side of the active rod 51, and the axis of the active rod 51 and the axis of the driven rod 52 are parallel to each other, and preferably the active rod 51 and the driven rod 52 are located between the plurality of frames 41 and the plurality of positioning pins 3; the active rod 51 and the driven rod 52 are both rotatably connected to the base plate 12, and the rotation axis of the active rod 51 and the rotation axis of the driven rod 52 coincide with their own axes.

[0067] Reference Figure 7Preferably, multiple transmission gears 53 are installed inside the base plate 12, and the control component 5 preferably includes two transmission gears 53. The two transmission gears 53 are respectively fixed on the active rod 51 and the driven rod 52, and the two transmission gears 53 are engaged with each other. The construction personnel control the rotation of the active rod 51 to drive the driven rod 52 to rotate synchronously in the opposite direction through the two transmission gears 53.

[0068] Back to Figure 5 Multiple turbines 54 are mounted within the base plate 12. The turbines 54 are rotatably connected to the base plate 12, and the rotation axis of the turbines 54 is perpendicular to the base plate 12 and coincides with the turbines' own axis. The turbines 54 are respectively fitted with the multiple frames 41 and the multiple positioning pins 3. The turbines 54 are threadedly engaged with the corresponding frames 41 or the corresponding positioning pins 3, and the rotation axis of the turbines 54 coincides with the axis of the corresponding frames 41 or the axis of the corresponding positioning pins 3. That is, the rotation of the turbines 54 relative to the base plate 12 can control the sliding of the corresponding frames 41 or the corresponding positioning pins 3 relative to the base plate 12.

[0069] Reference Figure 5 and Figure 7 A plurality of worm gears 55 are fixedly mounted on the active rod 51 and the driven rod 52, respectively. The plurality of worm gears 55 correspond one-to-one to the plurality of worm gears 54, and the worm gears 55 mesh with the corresponding worm gears 54. In this embodiment, preferably, after the construction personnel control the rotation of the active rod 51, the frame 41 can be controlled to slide by the meshing of the worm gears 54 and the worm gears 55. Simultaneously, the rotation of the active rod 51 drives the driven rod 52 to rotate synchronously in the opposite direction via the two transmission gears 53, and the meshing of the worm gears 54 and the worm gears 55 can control the positioning pin 3 to slide in the opposite direction relative to the frame 41.

[0070] In this embodiment, preferably, when the frame 41 slides relative to the base plate 12 until the roller 42 is exposed under the base plate 12, the positioning pin 3 will slide relative to the base plate 12 until its tail is retracted into the through-hole 121; and preferably, when the frame 41 slides relative to the base plate 12 until the roller 42 is just retracted into the inside of the base plate 12, the positioning pin 3 will slide relative to the base plate 12 until its tail is just about to pass through the through-hole 121.

[0071] The implementation principle of the assembled support structure for the trench 101 in the embodiment of the present application is as follows:

[0072] Before the supporting structure is hoisted into the groove 101, the multiple rollers 42 on the bottom plate 12 are all in an exposed state, which facilitates the movement of the supporting structure at the construction site; after the supporting structure is hoisted into the groove 101, the construction personnel can use the rollers 42 to adjust the position of the supporting structure in the groove 101; after the supporting structure is positioned in the groove 101, the first support assembly 21 is first adjusted to enable the two supporting seats 1 to support the groove 101. During this process, the rollers 42 will facilitate the positioning of the two supporting seats 1 in the groove 101. Shift; after the two side plates 11 are initially against the two side walls of the groove 101, operate the control component 5 to retract the multiple rollers 42 into the bottom plate 12, so that the bottom plate 12 is against the bottom wall of the groove 101; then continue to adjust the first support component 21 to make the two side plates 11 further against the two side walls of the groove 101, so that it can indeed support the groove 101; then operate the control component 5 again to make the multiple positioning nails 3 pass through the corresponding perforations 121 and penetrate into the soil layer below the groove 101.

[0073] Example 3:

[0074] Reference Figure 4 and Figure 6 The difference between this embodiment and embodiment 2 is that the supporting structure further includes a plurality of deformable members 6, and the deformable members 6 are protective bags 61 with a certain amount of filler 104 inside.

[0075] Reference Figure 6 In this embodiment, the preferred support structure includes two protective bags 61, and the two protective bags 61 are respectively fixedly installed on the end surface of the side plate 11 facing away from the other side plate 11, and the protective bags 61 replace the end surface of the side plate 11 to contact and resist the side wall of the groove 101.

[0076] The protective bladder 61 is made of an elastic material. In this embodiment, it is preferably made of a plastic material. The protective bladder 61 covers the end surface of the side panel 11 and defines a cavity 611 within the protective bladder 61 for storing the filler 104. In practice, one end of the protective bladder 61 has a material port for the filler 104 to enter and exit the cavity 611, though this port is omitted in the drawings. Since the protective bladder 61 containing the filler 104 is common in the prior art, its detailed description is omitted here.

[0077] In this embodiment, the filler 104 is preferably a gas. In other embodiments, the filler 104 may also be a substance that can flow freely in the cavity 611, such as water. When the side panel 11 contacts the sidewall of the groove 101 through the protective bladder 61, the protective bladder 61 can adaptively deform according to the different surface conditions of the sidewall of the groove 101, thereby adapting to the sidewall of the groove 101, increasing the contact area between the protective bladder 61 and the sidewall of the groove 101, and thereby improving the support effect of the side panel 11 on one side of the groove 101.

[0078] The implementation principle of the assembled support structure for the trench 101 in the embodiment of the present application is as follows:

[0079] Before the support structure is used, the filler 104 is added to or reduced in the protective bag 61 according to the surface conditions of the side wall of the groove 101 so that it has a certain deformation ability; after the support structure is hoisted into the groove 101, the first support assembly 21 is adjusted so that both side plates 11 are against the side walls of the groove 101 through the protective bag 61, thereby increasing the contact area between the protective bag 61 and the side walls of the groove 101, thereby improving the support effect of the side plate 11 on one side of the groove 101.

[0080] Example 4:

[0081] Reference Figure 6 and Figure 8 The difference between this embodiment and embodiment 3 lies in the supporting mechanism 2 and the deforming member 6, and this embodiment can be applied to grooves 101 with a larger depth.

[0082] Reference Figure 8 and Figure 9 For the support base 1 in the support mechanism 2, the width of its side plate 11 is preferably smaller than the depth of the groove 101. Furthermore, the support mechanism 2 further includes a plurality of auxiliary plates 24. The auxiliary plates 24 are preferably rectangular plates, and the length of the auxiliary plates 24 is preferably equal to the length of the support base 1. In this embodiment, the auxiliary plates 24 are also preferably made of steel.

[0083] The deformable member 6 is an elastic plate 62 capable of bending and deformation. Preferably, the elastic plate 62 is a rectangular plate-shaped structure, and the length of the elastic plate 62 is preferably equal to the length of the support base 1. Furthermore, the width and thickness of the elastic plate 62 are preferably equal to the width and thickness of the auxiliary plate 24, respectively. In this embodiment, the elastic plate 62 is preferably made of rubber and has a certain degree of elastic deformation recovery.

[0084] Multiple auxiliary plates 24 and multiple elastic plates 62 are respectively installed above the two side plates 11. The multiple auxiliary plates 24 and multiple elastic plates 62 above the same side plate 11 are spaced apart, that is, adjacent elastic plates 62 above the same side plate 11 are connected by the auxiliary plates 24. In this embodiment, the support mechanism 2 preferably includes a total of four auxiliary plates 24, and the support structure includes a total of four elastic plates 62, that is, a total of two auxiliary plates 24 and two elastic plates 62 are installed above the same side plate 11, and the end of the elastic plate 62 in the width direction close to the side plate 11 is fixedly connected to the end of the side plate 11 away from the bottom plate 12. In other embodiments, the number of auxiliary plates 24 and the number of elastic plates 62 can be adjusted according to the depth dimension of the groove 101.

[0085] The support mechanism 2 also includes multiple second support assemblies 22, which are installed between two corresponding auxiliary plates 24 on different sides. In this embodiment, the support mechanism 2 preferably includes four second support assemblies 22, with two second support assemblies 22 installed between two corresponding auxiliary plates 24 on different sides, and the two second support assemblies 22 are respectively located at the two ends of the auxiliary plates 24 in the longitudinal direction.

[0086] In this embodiment, the structure of the second support assembly 22 is preferably similar to that of the first support assembly 21, and the support mechanism 2 preferably includes three linkage assemblies 23, one linkage assembly 23 being used to link the four first support assemblies 21, and the other two linkage assemblies 23 are respectively installed between two groups of auxiliary plates 24, and are used to link the two second support assemblies 22 located between the corresponding two auxiliary plates 24, so as to facilitate construction personnel to adjust the distance between the corresponding two auxiliary plates 24.

[0087] Furthermore, the second support assembly 22 preferably further includes two connecting seats 221, which are respectively mounted on one end of the rotating rod 211 away from the corresponding movable rod 212 and one end of the movable rod 212 away from the corresponding rotating rod 211. One end of one connecting seat 221 is rotatably connected to the rotating rod 211, that is, one end of the rotating rod 211 is rotatably connected to the connecting seat 221, and the rotation axis of the rotating rod 211 relative to the connecting seat 221 coincides with the axis of the rotating rod 211; one end of the other connecting seat 221 is fixedly connected to the movable rod 212, and the other ends of the two connecting seats 221 are respectively rotatably connected to two adjacent auxiliary plates 24, and the rotation axis of the connecting seat 221 relative to the auxiliary plate 24 is parallel to the length direction of the side plate 11.

[0088] After adjusting the second supporting assembly 22 to drive the corresponding two auxiliary plates 24 to abut against the two side walls of the groove 101, the auxiliary plates 24 can rotate relative to the connecting seat 221 to adapt themselves to the side wall surface of the groove 101, thereby increasing the contact area between the auxiliary plates 24 and the side wall surface of the groove 101 as much as possible, and improving the supporting effect of the auxiliary plates 24 on the side walls of the groove 101.

[0089] Furthermore, the support structure further includes a plurality of limiters 7. In this embodiment, the support structure preferably includes two limiters 7, which respectively play the above-mentioned role on the two second support assemblies 22 located at both ends of the auxiliary plate 24.

[0090] The bottom of the limiting member 7 is fixedly connected to the support seat 1, preferably the bottom of the limiting member 7 is fixedly connected to the side plate 11 of the support seat 1; the limiting member 7 is provided with two clearance holes 71 for the rotating rod 211 to pass through, and the corresponding two rotating rods 211 are simultaneously penetrated and cooperated with the limiting member 7.

[0091] During the process in which the limit member 7 plays the above-mentioned role on the two second support components 22, the limit member 7 keeps the distance between the two second support components 22 unchanged, and at the same time enables the second support components 22 to maintain a horizontal state during the adjustment process, thereby reducing the probability of the auxiliary plate 24 rotating and offsetting after the elastic plate 62 is bent and deformed, so that the auxiliary plate 24 and the elastic plate 62 can stably support the appropriate position of the groove 101 side wall.

[0092] At the same time, after the auxiliary plate 24 rotates, the elastic plate 62 adjacent to it can undergo appropriate bending deformation. The elastic plate 62 after bending deformation can adapt to the corresponding part of the side wall of the groove 101. At the same time, the elastic plate 62 after bending deformation has a tendency to recover. The tendency of its elastic deformation recovery can increase its own force on the side wall of the groove 101, thereby improving its own support effect on the side wall of the groove 101; and, its elastic deformation recovery tendency can also drive the adjacent auxiliary plate 24 to rotate and reset, thereby increasing the force of the auxiliary plate 24 on the side wall of the groove 101, and then improving its own support effect on the side wall of the groove 101.

[0093] Furthermore, the end surface of the auxiliary plate 24 facing away from the second support assembly 22 preferably has a concavo-convex pattern 105, and the end surface of the side plate 11 of the support base 1 facing away from the first support assembly 21 also has a concavo-convex pattern 105. This further increases the contact area between the auxiliary plate 24 and the side plate 11 and the sidewalls of the groove 101, thereby further improving the supporting effect of the auxiliary plate 24 and the side plate 11 on the sidewalls of the groove 101. In this embodiment, since the concavo-convex pattern 105 is common in the prior art, it will not be described in detail here, and the concavo-convex pattern 105 is only briefly shown in the accompanying drawings.

[0094] The implementation principle of the assembled support structure for the trench 101 in the embodiment of the present application is as follows:

[0095] After the supporting structure is hoisted into the groove 101, the first supporting assembly 21 is adjusted so that the two supporting seats 1 support the bottom of the groove 101; then the multiple groups of second supporting assemblies 22 are adjusted from top to bottom so that the corresponding two auxiliary plates 24 are respectively against the two side walls of the groove 101, and the elastic plate 62 is bent and deformed as the position of the adjacent auxiliary plates 24 changes. The bent and deformed elastic plate 62 also abuts against the side wall of the groove 101 and adapts to the side wall of the groove 101. Finally, the multiple auxiliary plates 24 and the multiple elastic plates 62 jointly support the top of the side wall of the groove 101, and can adapt to the surfaces of the side wall of the groove 101 in different conditions.

[0096] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
