[0002] Utility tunnel construction is an important part of urban infrastructure construction, which involves the layout and maintenance of underground pipelines to ensure the normal operation of urban water supply, drainage, electricity, communication and other systems.

[0003] During the construction of existing utility tunnels, it is first necessary to conduct exploration of the on-site geological conditions, pipeline layout and surrounding environment, then excavate the soil, and a support system needs to be set up to avoid soil slope collapse.

[0004] The existing support systems often use wooden boards and struts for support, with the wooden boards fitted to the trench slope and the struts supported on the other side of the wooden boards.

[0005] However, this support system is cumbersome to operate. Different slope angles require struts of various lengths to ensure that the wooden boards fit the slope surface, which requires a large number of struts and results in a narrow construction space in the trench.

[0016] In some embodiments, the limiting component includes:

[0017] The installation component is arranged on the upper part of the support rod, and the axis coincides with the axis of the support rod; and

[0018] The clamping component is arranged between the installation component and the support rod and is used to fix the distance between the installation component and the support rod.

[0019] In some embodiments, the installation component includes:

[0020] The installation rod has an axis that coincides with the axis of the support rod;

[0021] The end of the swing rod away from the support plate is hinged to the top end of the installation rod; and

[0022] The second link is arranged in parallel with the lower part of the swing rod, and the two ends of the second link are respectively hinged to the installation rod and the translation rod.

[0023] In some embodiments, the clamping component includes:

Since the length of the rocker lever between the support rod and the bottom end of the support plate is greater than the distance between the support rod and the support plate, when the longer rocker lever swings upward, the distance between the upper part of the support plate and the support rod increases, causing the support plate to tilt towards the slope surface until it fits the slope surface. Finally, the support plate is fixed by the limiting component, so that the support plate will not tip over when subjected to the extrusion of the slope surface.

For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific situations.

[0055] As described above, in the traditional construction of trench slope support, since a large number of support plates require a large number of support rods for support, construction workers need to continuously install support rods, resulting in low construction efficiency.

[0056] In order to at least partially solve the above-mentioned problems and other potential problems, the support device includes a support plate and a base for installing the support plate, and a jacking mechanism, the bottom end of the support plate is hinged to the base surface, the jacking mechanism is arranged between one side of the support plate and the base, and the jacking mechanism includes a support rod vertically arranged on the base surface; a tilt rod, the middle section of the support rod is hinged to the middle section of the support rod; one end of the tilt rod is arranged on one side of the support plate; wherein the length of the tilt rod between the support rod and the bottom end of the support plate is greater than the distance between the support rod and the support plate; and a limit assembly, the two ends of which are respectively connected to the top end of the support rod and the side of the support plate close to the support rod, the limit assembly is used to fix the distance between the top end of the support rod and the support plate, thereby reducing the labor intensity of construction workers while improving construction efficiency.

[0057] The trench support device according to an embodiment of the present application is exemplarily described below with reference to the accompanying drawings. Figure 1 A schematic structural diagram of a support device according to an embodiment of the present application is shown. Figure 2 A schematic structural diagram of a position limiting assembly according to an embodiment of the present application is shown. Figure 6 A schematic diagram of the installation of a square trench support device according to an embodiment of the present application is shown. Figure 7 A schematic diagram of the installation of an inverted frustum-shaped trench support device according to an embodiment of the present application is shown.

[0058] A trench support device includes a support plate 2 and a base 3 for installing the support plate 2, and an extension mechanism 1, wherein the bottom end of the support plate 2 is hinged to the surface of the base 3, and the extension mechanism 1 is arranged between one side of the support plate 2 and the base 3, and the extension mechanism 1 includes a support rod 5 vertically arranged on the surface of the base 3; a tilting rod 11, the middle section of which is hinged to the middle section of the support rod 5; one end of the tilting rod 11 is arranged on one side of the support plate 2; wherein the length of the tilting rod 11 located between the support rod 5 and the bottom end of the support plate 2 is greater than the distance between the support rod 5 and the support plate 2; and a limiting component 12, the two ends of which are respectively connected to the top of the support rod 5 and the side of the support plate 2 close to the support rod 5, and the limiting component 12 is used to fix the distance between the top of the support rod 5 and the support plate 2.

[0059] When in use, stepping on one end of the tilting rod 11 causes the other end of the tilting rod 11 to tilt up. Since the length of the tilting rod 11 between the support rod 5 and the bottom end of the support plate 2 is greater than the distance between the support rod 5 and the support plate 2, when the longer tilting rod 11 swings upward, the distance between the upper part of the support plate 2 and the support rod 5 increases, and the support plate 2 tilts toward the slope around the hinge with the base 3 until it fits with the slope surface. Finally, the support plate 2 is fixed with the limit assembly 12, so that the support plate 2 will not fall over when squeezed by the slope surface. The support installation of the support plate 2 can be completed by only stepping on the tilting rod 11, which improves construction efficiency and reduces the labor intensity of construction workers.

[0060] It should be noted that a plurality of reinforcing nails 4 are provided on the bottom surface of the base 3. By stepping on the base 3, the reinforcing nails 4 are embedded into the soil at the bottom of the groove, further improving the installation strength of the support plate 2 and preventing the support plate 2 from tilting under force.

[0061] It should be noted that the support plate 2 is connected to the base 3 by a pin. The support plate 2 swings around the pin. When the groove is in the shape of an inverted frustum, the pin is removed from the base 3, and the flat support plate 2 is replaced with a curved sector plate. By splicing a plurality of sector plates, the support for the groove in the shape of an inverted frustum can be realized.

[0062] In addition, since the excavated soil is loose, heavy rain erosion is likely to cause the gap between the support plate 2 and the slope to increase. In the traditional support system, construction workers need to replace longer support rods to further make the guard plate fit the slope and prevent rainwater from backflow, which further increases the labor intensity of the construction workers. However, for the support device provided in this application, it only needs to step on the lever 11 again to further make the support plate 2 move closer to the slope.

[0063] Figure 1 Shows a schematic structural diagram of a support device according to an embodiment of the present application. Figure 2 Shows a schematic structural diagram of a limiting component according to an embodiment of the present application.

[0064] The top extension mechanism 1 further includes: a translation rod 13, parallel to the support rod 5 and arranged between the support rod 5 and the support plate 2; one end of the lever 11 close to the support plate 2 is hinged to the bottom end of the translation rod 13; and a first connecting rod 14, parallel to the upper part of the lever 11, with both ends hinged to the support rod 5 and the translation rod 13 respectively; a swing rod 15, the middle section of which is hinged to the top end of the translation rod 13, and one end of the swing rod 15 is hinged to the surface of the support plate 2.

[0065] During use, step on the lever 11, one end of the lever 11 swings around the fulcrum, so that the lever 11 pushes the translation rod 13 to move towards the support plate 2. The first connecting rod 14, the lever 11, the translation rod 13, and the support rod 5 form a parallelogram structure, enabling the translation rod 13 to maintain translation between the support rod 5 and the support plate 2.

[0066] Figure 1 Shows a schematic structural diagram of a support device according to an embodiment of the present application. Figure 2 Shows a schematic structural diagram of a limiting component according to an embodiment of the present application.

[0067] The limiting component 12 includes: a mounting component 121, arranged on the upper part of the support rod 5, with its axis coinciding with the axis of the support rod 5; and a clamping component 122, arranged between the mounting component 121 and the support rod 5, for fixing the distance between the mounting component 121 and the support rod 5.

[0068] When in use, the installation component 121 is used to install the clamping component 122. The installation component 121 and the clamping component 122 are respectively used to connect the support rod 5 and the translation plate, so that after the translation plate is lifted to a certain distance by the tilting rod 11, the clamping component 122 can fix the above distance.

Figure 2 A schematic structural diagram of a position limiting assembly according to an embodiment of the present application is shown. Figure 3 Show Figure 2 Schematic diagram of the enlarged area A in the middle. Figure 4 A schematic diagram of the mounting plate structure according to an embodiment of the present application is shown.

[0070] The mounting assembly 121 includes: a mounting rod 1211, the axis of which coincides with the axis of the support rod 5; the end of the rocker arm 15 away from the support plate 2 is hinged to the top of the mounting rod 1211; and a second connecting rod 1212 arranged parallel to the lower part of the rocker arm 15, the two ends of the second connecting rod 1212 are respectively hinged to the mounting rod 1211 and the translation rod 13.

[0071] During use, when the translation rod 13 swings toward the support plate 2, the rocker arm 15 forms a parallelogram structure with the second connecting rod 1212, the mounting rod 1211, and the translation rod 13. When the translation rod 13 moves parallel to the support rod 5, the second connecting rod 1212 and the rocker arm 15 drive the mounting rod 1211 to move upward, thereby driving the clamping assembly 122 to move at the top of the support rod 5. The clamping assembly 122 can thereby fix the distance of its own movement, thereby achieving the purpose of fixing the position of the translation rod 13.

Figure 4 A schematic diagram of the mounting plate structure according to an embodiment of the present application is shown. Figure 5 A schematic diagram of an L-shaped rod structure according to an embodiment of the present application is shown.

[0073] The clamping assembly 122 includes: a rack 1221, which is vertically arranged between the mounting rod 1211 and the support rod 5, and the top end is connected to the mounting rod 1211; a sliding hole 1222, which is arranged on the top surface of the support rod 5, and the rack 1221 is slidably arranged in the sliding hole 1222; and an adjustment hole 1223, which is arranged on the side wall of the support rod 5, and one end is connected to the inner wall of the sliding hole 1222; an L-shaped rod 1224, whose opening faces the mounting rod 1211, and one end of the L-shaped rod 1224 passes through the adjustment hole 2223 and cooperates with the tooth groove of the rack 1221; two groups of hinged rods 1225 are respectively arranged on both sides of the L-shaped rod 1224, and the two groups of hinged rods 1225 are respectively hinged to the mounting plates 1226; wherein the mounting plates 1226 are provided in two groups, the two groups of mounting plates 1226 are arranged on the surface of the support rod 5, and the L-shaped rod 1224 is arranged between the two groups of mounting plates 1226.

[0074] When the support plate 2 is in contact with the slope, the tilting rod 11 is no longer stepped on. When the rack 1221 is affected by gravity or the support plate 2 is subjected to the pressure of the soil slope and the rack 1221 moves down, the L-shaped rod 1224 is pushed downward by the rack 1221 on the side close to the rack 1221. At this time, the other end of the L-shaped rod 1224 abuts against the surface of the support rod 5, thereby preventing the L-shaped rod 1224 from continuing to swing. Then, the height of the rack 1221 is fixed by one end of the L-shaped rod 1224 abutting against the surface of the support rod 5.

[0077] In use, when it is necessary to disassemble the support plate 2, drag the L-shaped rod 1224 to slide in the escape groove 1227 of the mounting plate 1226, so that the L-shaped rod drives the articulated rod 1225 to slide away from the rack 1221, and then the purpose of disengaging the L-shaped rod 1224 from the tooth groove of the rack 1221 is achieved. The rack 1221 can fall and be recycled in the sliding hole 1222, and the disassembly of the support plate 2 can be completed.
