[0032] Embodiments of the present application will be described below in conjunction with the accompanying drawings. It should be understood that the embodiments described below in conjunction with the accompanying drawings are exemplary descriptions of the technical solutions of the embodiments of the present application, and do not limit the technical solutions of the embodiments of the present application.

[0034] In order to make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below in conjunction with the accompanying drawings.

[0035] In the related art, municipal engineering pipe network construction is usually constructed by using the open excavation method, and the base groove needs to be well supported during the construction by using the open excavation method. The current supporting method usually needs to fix a supporting plate on the base groove slope. After excavation, workers need to go down to the bottom of the base groove, first backfill a sand cushion on the base, and then place the pipe after compaction and other treatments of the sand cushion, and then butt joint the two pipes, so that the workers are not very convenient to operate at the bottom of the base groove, the construction efficiency is low, and the pipe may not be placed stably on the sand cushion, thereby affecting the installation and butt joint effect of the pipe.

[0036] To solve the technical problems of the prior art that workers are inconvenient to operate at the bottom of the foundation trench, the construction efficiency is low, and the pipeline installation effect is poor, with reference to Figures 1-4 The supporting device for supporting the foundation trench 500 of the pipeline 600 is provided.

[0037] The supporting device comprises two oppositely arranged supporting plates 100, a bracing rod 200 connected between the two supporting plates 100, and an arc-shaped plate 300 arranged at the bottom of the two supporting plates 100. The supporting plate 100 is configured to be arranged on the side wall of the foundation trench 500, and the arc-shaped plate 300 has a fitting surface 310 arched away from the side of the supporting plate 100. The fitting surface 310 is used to form an arc-shaped groove at the bottom of the foundation trench 500, which is fitted with the outer peripheral wall of the pipeline 600.

[0038] The supporting plate 100, the bracing rod 200, and the arc-shaped plate 300 of the present application form an integrated assembly structure. During construction, the supporting device can be directly hoisted into the foundation trench 500 for support, thereby eliminating the step of sequentially installing the supporting plate 100 on the side slope of the foundation trench 500, and improving the construction efficiency. The integrated supporting device can be used to excavate and sink simultaneously during the support of the foundation trench 500, which can make the support of the surrounding foundation trench 500 more stable, ensure the safety of construction, and also help to improve the construction efficiency.

[0039] By arranging the arc-shaped plate 300 at the bottom of the supporting plate 100 as the bottom formwork of the supporting device, after excavation, the fitting surface 310 of the arc-shaped plate 300 is used to fit with the foundation, compact the sand cushion layer 700 at the foundation, and arrange the shape of the foundation trench 500 according to the shape of the fitting surface 310, so that the foundation forms an arc-shaped groove for fitting with the outer peripheral wall of the pipeline 600. Then, the worker places the pipeline 600 into the arc-shaped groove, without the need for the worker to process the foundation, thereby improving the construction efficiency.

[0040] Further, with reference to Figure 4 By compacting the sand cushion layer 700 at the foundation with the arc-shaped plate 300, it can also avoid uneven backfilling of the sand cushion layer 700 on both sides directly below the pipeline 600 caused by manual processing, which can effectively improve the installation effect of the pipeline 600. At the same time, the arrangement of the arc-shaped groove also limits the placement position of the pipeline 600, avoiding displacement or rolling of the pipeline 600 at the foundation, facilitating the butt joint of the pipeline 600, and improving the butt joint installation efficiency of the pipeline 600. Compacting the sand cushion layer 700 at the foundation with the arc-shaped plate 300 can also reduce the safety risks caused by sudden problems such as sudden gushing and bulging of the foundation trench 500 to a certain extent, and ensure the safety of construction personnel.

[0041] Optionally, with reference to Figure 1The arc-shaped plate 300 extends along the length direction of the support plate 100, and the two side edges of the arc-shaped plate 300 are detachably connected to the bottom of the two support plates 100 respectively.

[0042] The arc-shaped plate 300 and the support plate 100 are detachably connected, which facilitates the assembly and disassembly of the support device, thereby improving the assembly efficiency of the support device, and reducing the floor space occupied by the support device during transportation and storage, thereby saving the transportation cost to a certain extent.

[0043] Optionally, the two side edges of the arc-shaped plate 300 are detachably connected to the bottom of the two support plates 100 by bolts.

[0044] Alternatively, the two side edges of the arc-shaped plate 300 are provided with guide rails (not shown in the figure) extending along the length direction of the arc-shaped plate 300, and the bottom of the support plate 100 is provided with a guide rail seat (not shown in the figure), so that the arc-shaped plate 300 is slidingly arranged on the bottom of the support plate 100.

[0045] Alternatively, the two side edges of the arc-shaped plate 300 are provided with buckles (not shown in the figure), and the bottom of the support plate 100 is provided with a buckle seat (not shown in the figure) for cooperating with the buckle, so that the arc-shaped plate 300 is detachably connected to the support plate 100 by the buckle.

[0046] Optionally, the arc-shaped plate 300 includes at least two kinds. In a plane perpendicular to the arc-shaped plate 300 or the support plate 100, the arc-shaped plate 300 is in an arc segment, and the curvature radii of the arc-shaped plates 300 of different kinds are different, and the arc-shaped plates 300 of different curvature radii are used to adapt to pipelines 600 of different outer diameters.

[0047] The arc-shaped plate 300 is detachably connected to the support plate 100, and the arc-shaped plate 300 is provided with at least two kinds of different curvature radii. By processing a plurality of arc-shaped plates 300 of different kinds, when placing a pipeline 600 of different outer diameter, the kind of the arc-shaped plate 300 can be quickly replaced according to the outer diameter of the pipeline 600, so that the arc-shaped groove formed by pressing the sand cushion layer 700 of the base by the fitting surface 310 of the arc-shaped plate 300 is fitted with the outer side wall of the pipeline 600, thereby improving the limiting effect on the pipeline 600, avoiding displacement or rolling of the pipeline 600 after being placed in the base, and thereby facilitating subsequent pipeline 600 butt joint work, and improving the pipeline 600 butt joint efficiency.

[0048] Optionally, referring to Figure 1 and Figure 2 , the inner side of at least one support plate 100 is provided with an operation platform 400. In another optional embodiment, the operation platform 400 is arranged between the two support plates 100.

[0049] By arranging the operation platform 400 on the supporting device of the present application, a standing space is provided for the workers, and a safe and reliable operation environment is provided for the workers, so that the workers can directly stand on the operation platform 400 to place the pipeline 600 and butt joint the pipeline 600, without the need to enter the base for butt joint of the pipeline 600, which can effectively improve the installation and butt joint efficiency of the pipeline 600, and to a certain extent, reduce the safety risks caused by sudden problems such as sudden surge and bulging of the base groove 500, and avoid safety accidents such as burying of personnel caused by sudden situations in the first time, and ensure the construction safety.

[0050] Optionally, referring to Figure 2 , the supporting rods 200 are arranged at intervals between the two supporting plates 100, and the upper part of the operation platform 400 is not blocked by the supporting rods 200. So that the workers can move freely when standing on the operation platform 400. Or the height difference between the upper supporting rod 200 and the operation platform 400 is greater than the height threshold. The height threshold described in the present application is at least greater than the average height of the construction personnel, so as to reserve a certain activity space for the construction personnel, so that the construction personnel can move freely on the operation platform 400, and the construction efficiency is ensured.

[0051] Optionally, referring to Figure 2 , along the length direction of the supporting plate 100, the operation platform 400 and the arc-shaped plate 300 have a spacing. In the present application, the height of the operation platform 400 is greater than the height of the arc-shaped plate 300.

[0052] By arranging the height of the operation platform 400 to be greater than the height of the arc-shaped plate 300, the height of the operation platform 400 is sufficient from the base, so as to ensure that the workers have sufficient safety distance from the base when standing on the operation platform 400, and to reserve a certain buffer distance for the workers in the event of sudden situations such as sudden surge and deformation of the base, thereby reducing the harm to the workers and reducing the safety risks during construction.

[0053] Optionally, referring to Figure 2 , the supporting plate 100 comprises a structural plate 110 and a plurality of reinforcing rods 120, and the plurality of reinforcing rods 120 are arranged in a grid shape on at least one side of the structural plate 110.

[0054] The present application can improve the supporting strength of the supporting plate 100 by arranging a plurality of reinforcing rods 120 on at least one side of the structural plate 110. By arranging the plurality of reinforcing rods 120 in a grid shape on the structural plate 110 in the horizontal and vertical directions, the stress of each position of the supporting plate 100 is more uniform, thereby further improving the supporting strength of the supporting plate 100. In the present application, the plurality of reinforcing rods 120 are arranged in a grid shape on one side of the reinforcing rod 120, and the plurality of supporting rods 200 are connected to the side of the structural plate 110 away from the reinforcing rod 120.

[0055] Optionally, referring to Figure 2 , the operation platform 400 is detachably arranged between two reinforcing rods 120 horizontally extending along the length direction of the support plate 100.

[0056] In order to facilitate the transportation, storage and assembly of the support device of the present application, the operation platform 400 is detachably connected with the support plate 100. And by detachably connecting the operation platform 400 between two reinforcing rods 120 horizontally extending along the length direction of the support plate 100, the connection of the operation platform 400 and the support plate 100 can be facilitated without affecting the stress uniformity of the support plate 100 and ensuring the support strength of the support plate 100, thereby improving the assembly efficiency of the operation platform 400 and the support plate 100 and improving the stability of the operation platform 400, and ensuring the construction safety of workers on the operation platform 400.

[0057] Optionally, the reinforcing rod 120 of the present application uses square tube, and the reinforcing rod 120 is detachably mounted on the structural plate 110 by bolts and other fasteners.

[0058] Optionally, the two ends of the operation platform 400 are arranged on the top of the two reinforcing rods 120, and are detachably mounted on the reinforcing rods 120 by bolts and other fasteners. The reinforcing rods 120 and the structural plate 110 can disperse a part of the gravity borne by the operation platform 400, thereby improving the carrying capacity of the operation platform 400 to a certain extent and ensuring the construction safety of workers on the operation platform 400.

[0059] Optionally, the bracing rod 200 is detachably connected with the support plate 100. Thus, the bracing rod 200 of appropriate length can be replaced according to the width of the foundation trench 500 to be supported, thereby expanding the use scenarios of the support device of the present application. The support plate 100 of the present application can be repeatedly used in various foundation trench 500 support constructions, thereby improving the material reuse rate and reducing the material turnover consumption.

[0060] Optionally, the bracing rod 200 is arranged at the intersection position formed by the horizontal reinforcing rod 120 and the vertical reinforcing rod 120, which can effectively ensure the bracing effect of the bracing rod 200 and improve the support strength of the support plate 100.

[0061] Optionally, the support device of the present application further comprises at least one connecting piece (not shown in the figure) for connecting with external hoisting equipment. The connecting piece can be selected from buckles, lifting belts and other components that are convenient to connect with external hoisting equipment.

[0062] The support device of the application is an integrated assembly structure, which can be excavated and sunk at the same time when supporting the foundation trench 500, so that the surrounding foundation trench 500 is more stable and safe during construction. By providing a connecting piece on the support device, the support device can be connected to the external hoisting equipment to drive the support device to sink, hoist out or horizontally hoist to the next foundation trench 500 to be supported, which is beneficial to improve the construction efficiency and the support effect of the foundation trench 500.

[0063] Optionally, one connecting piece is arranged on the top of each support plate 100, which ensures the convenience and stability of hoisting.

[0064] Optionally, referring to Figures 1-4 , when the support device of the application is used for foundation trench 500 support and pipeline 600 installation construction, the steps S101-S104 are included:

[0065] S101: Excavate the foundation trench 500.

[0066] Optionally, excavate the foundation trench 500 according to the designed width, then connect the connecting piece on the support device of the application to the external hoisting equipment, then put the support device of the application into the foundation trench 500, so that the two side support plates 100 abut against the inner wall of the foundation trench 500. After the support is completed, continue to excavate.

[0067] Optionally, during excavation, the support method of excavating a section of the foundation trench 500 and then lowering a section of the support device of the application can more stably support the surrounding foundation trench 500 and reduce the construction risk.

[0068] The support device of the application is an integrated assembly structure, which can be dragged in parallel during construction, so only a certain length and height of the support device needs to be processed as a section, and after excavating a section of the foundation trench 500, a section of the support device can be installed according to the depth of the foundation trench 500. The application of the device can greatly reduce the investment in support materials, improve construction efficiency, and improve material turnover efficiency.

[0069] S102: Pipeline 600 cushion construction.

[0070] Optionally, after the foundation trench 500 is excavated to the designed elevation, backfill the sand and stone material as the sand cushion 700 of the pipeline 600, then lower the support device of the application to the designed elevation, use the arc-shaped plate 300 at the bottom to compact the sand cushion 700, and form an arc-shaped groove.

[0071] S103: Install the pipeline 600.

[0072] Optionally, the workers enter the foundation trench 500 and stand on the operation platform 400, and then use the hoisting equipment to hoist the pipes 600 into the foundation trench 500, and temporarily hoist the pipes 600 on the operation platform 400. At least two pipes 600 can be placed on the operation platform 400, and when the at least two pipes 600 are placed stably, the workers lower the pipes 600 and stabilize them on the arc-shaped plate 300, and then lower another pipe 600, and then butt the two pipes 600.

[0073] After the butt joint of the two pipes 600 is completed, the next section of the foundation trench 500 is excavated and treated according to the steps S101-S102, and then one end of the pipe 600 is controlled, and then the supporting device of the application is horizontally dragged into the next section of the foundation trench 500, so that the pipe 600 and the arc-shaped plate 300 slide relative to each other, and when the pipe 600 is completely separated from the arc-shaped plate 300, the pipe 600 naturally falls into the arc-shaped groove formed by the compacted abutting surface 310 of the arc-shaped plate 300, without the workers backfilling the sand cushion layer 700 on the foundation and treating the shape of the sand cushion layer 700, saving the labor cost of the workers, improving the work efficiency, and improving the installation effect of the pipe 600.

[0074] S104: Pipe 600 backfilling.

[0075] After the next section of the foundation trench 500 is excavated, the supporting device of the application can be hoisted out by the hoisting equipment or supported out by the excavator to the next section of the foundation trench 500 for construction. The current section of the foundation trench 500 can be backfilled according to the design requirements.

[0076] The technical scheme provided by the embodiment of the application has the following beneficial technical effects:

[0077] The supporting plate 100, the counter-bracing rod 200, and the arc-shaped plate 300 of the application form an integrated assembly structure, which can be directly hoisted into the foundation trench 500 for supporting during construction, thereby omitting the step of sequentially installing the supporting plates 100 on the side slope of the foundation trench 500, and improving the supporting construction efficiency.

[0078] The arc-shaped plate 300 is arranged at the bottom of the supporting plate 100 as a bottom form plate of the supporting device, and after excavation, the abutting surface 310 of the arc-shaped plate 300 is used to abut the foundation to compact the sand cushion layer 700 at the foundation, so as to arrange the shape of the foundation trench 500 according to the shape of the abutting surface 310, so that the foundation forms an arc-shaped groove for abutting the outer peripheral wall of the pipe 600. Then the workers place the pipe 600 into the arc-shaped groove, without the workers treating the foundation, thereby improving the construction efficiency. Meanwhile, the arrangement of the arc-shaped groove limits the placement position of the pipe 600, avoids the rolling of the pipe 600 on the foundation, facilitates the butt joint of the pipe 600, and improves the butt joint installation efficiency and installation effect of the pipe 600.

[0079] By processing a plurality of different kinds of arc-shaped plates 300, when placing different outer diameter pipelines 600, the kind of arc-shaped plate 300 can be quickly replaced according to the outer diameter of the pipeline 600, the limiting effect on the pipeline 600 is improved, and the stability of the pipeline 600 after installation is improved.

[0080] By providing the operation platform 400 on the supporting device of the application, a standing space is provided for the workers, and a safe and reliable operation environment is provided for the workers, which reduces the safety risks caused by sudden problems such as sudden surge and bulge of the foundation groove 500 to a certain extent, and ensures the construction safety.

[0081] The support rod 200, the arc-shaped plate 300, the operation platform 400 and the supporting plate 100 are detachably connected, so that each part of the supporting device of the application can be processed and customized according to the specific circumstances of the project, has strong applicability, can improve the material reuse rate, and reduce the material turnover consumption.
