[0028] See appendix Figure 1-6 The diagram shows a novel foundation pit trench support structure. The support structure includes two sets of opposing support plates 1. Each support plate 1 has a base 4 at its bottom. Each set of support plates 1 includes multiple single plates 2 connected in a detachable manner. The two sets of support plates 1 are arranged opposite each other, and a telescopic rod 3 is arranged between the two sets of support plates 1. The two ends of the telescopic rod 3 are detachably connected to one set of support plates 1. The telescopic rod 3 includes a main rod 300. Both ends of the main rod 300 are equipped with coarse adjustment rods 301 that can move and be positioned along its axial direction. The outer end of each coarse adjustment rod 301 is equipped with a fine adjustment rod 302 that can move and be positioned along its axial direction.

[0029] Typically, the pressure borne by the support structure comes from both sides of the trench. Therefore, the support structure uses two sets of opposing support plates 1. The anchors 4 of the support plates 1 are inserted into the bottom of the trench. Each support plate 1 is assembled from multiple single plates 2. The connection between the multiple single plates 2 can be disassembled to enhance the ease of assembly and disassembly, making manual assembly and disassembly possible and reducing the need for heavy machinery. The two sets of support plates 1 are supported by telescopic rods 3. The number of telescopic rods 3 is not limited and can be selected according to specific needs. Usually, multiple telescopic rods 3 are distributed at both ends and in the middle of the two sets of support plates 1. The telescopic rods 3 have two-level adjustment functions, coarse and fine, which can quickly adjust the support length to the correct position, improving the assembly efficiency of the support structure. With the support of the telescopic rods 3, the two sets of support plates 1 are stably supported in the trench for construction.

[0030] In addition, a handle 304 can be installed on the telescopic rod 3, which is usually located in the middle.

[0031] Support plate 1 is usually square, and each single plate 2 is also often square. There are many ways to assemble single plates 2, such as single plates 2 being arranged vertically or horizontally side by side.

[0032] For example, the multiple single boards 2 include two single boards 212 and 222 that are assembled vertically. The second single board 222 is equipped with a first pin 204, which is inserted into the first single board 212. The first single board 212 is provided with a longitudinally penetrating first cavity 211, and the second single board 222 is provided with a longitudinally penetrating second cavity 221. The first cavity 211 and the second cavity 221 correspond to each other. A connecting rod 203 is inserted into the first cavity 211 and the second cavity 221, and the connecting rod 203 is connected to the first single board 212 and the second single board 222 respectively through a second pin.

[0033] See appendix Figure 5The first single plate 212 is located above the second single plate 222. A first pin 204 is installed on the second single plate 222. When the first single plate 212 and the second single plate 222 are assembled, the first pin 204 is inserted into the corresponding hole on the first single plate 212.

[0034] A pin is a pluggable structure that is simple and quick to operate. Utilizing the pin in the connection between the first single plate 212 and the second single plate 222 improves the assembly efficiency of the two single plates 2. The bottom edge of the first single plate 212 abuts against the top edge of the second single plate 222 using a small fixing plate. The lower end of the fixing plate is bolted to the top edge of the second single plate 222. The upper end of the fixing plate has corresponding holes with the bottom edge of the first single plate 212, and then the first pin 204 is horizontally inserted into these holes.

[0035] The two single-panel boards 2, arranged vertically, not only have connecting structures at their adjacent top and bottom edges, but also utilize a longitudinal structure to strengthen the connection. Specifically, they are both equipped with longitudinal slot structures, in which connecting rods 203 are installed. The connecting rods 203 are connected to the two single-panel boards 2 via pins. Specifically, first slots 211 are provided at both ends of the first single-panel board 212, and second slots 221 are provided at both ends of the second single-panel board 222. When the first single-panel board 212 and the second single-panel board 222 are assembled vertically, the corresponding first slots 211 and second slots 221 are connected. The connecting rod 203 is inserted from the end of the slot so that one end is located in the first slot 211 and the other end is located in the second slot 221. Then, a second pin is used to connect one end of the connecting rod 203 to the first single-panel board 212 and the other end to the second single-panel board 222. Thus, the connecting rod 203 further enhances the stability of the connection between the two single boards 2 in the groove cavity, and the assembly method of the connecting rod 203 is also convenient for disassembly and assembly.

[0036] The multiple single plates 2 include two plates assembled side-by-side horizontally. Based on the aforementioned scheme, the following description uses the addition of a third single plate 232 and a fourth single plate 242 as an example. The multiple single plates 2 also include a third single plate 232 and a fourth single plate 242. One end of the first single plate 212 and the second single plate 222 is provided with a channel 202. The third single plate 232 and the fourth single plate 242 are respectively embedded in the two channels 202, and the corresponding single plates 2 are connected by a third pin. The channels 202 of both the first single plate 212 and the second single plate 222 extend longitudinally along their ends. The third single plate 232 is embedded in the channel 202 of the first single plate 212, and the fourth single plate 242 is embedded in the channel 202 of the second single plate 222. Then, they are locked together using the second pin, thereby forming the support plate 1. This assembly method is simple and convenient, can be achieved by multiple people working together, and can reduce the involvement of heavy machinery.

[0037] In some embodiments, the end of the fine adjustment rod 302 is provided with a supporting plate, and the front end of the supporting plate is provided with a positioning pin 303. The support plate 1 is provided with a positioning groove 200 that fits into the supporting plate, and the positioning pin 303 is connected to the positioning groove 200. The telescopic rod 3 abuts against the support plate 1 through the supporting plates at both ends, and the positioning pin 303 at the front end of the supporting plate is embedded in the positioning groove 200, which enhances the stability of the telescopic rod 3. Furthermore, multiple positioning grooves 200 can be provided on the support plate 1 to facilitate the selection of different positions for the telescopic rod 3 according to actual conditions.

[0038] In some embodiments, the coarse adjustment rod 301 is inserted into the end of the main rod 300. Both the main rod 300 and the coarse adjustment rod 301 are provided with a plurality of axially distributed first adjustment holes, and the coarse adjustment rod 301 is provided with a plurality of axially distributed second adjustment holes. The coarse adjustment rod 301 controls the axial movement of the first adjustment holes and the second adjustment holes relative to the main rod 300. The corresponding first adjustment holes and second adjustment holes are locked by a fourth pin 305.

[0039] The main rod 300 is hollow inside, into which the coarse adjustment rod 301 is inserted. The coarse adjustment rod 301 is moved axially to adjust the appropriate length. A set of first and second adjustment holes are aligned, and then a fourth pin 305 is inserted to fix the length. The fine adjustment rod 302 is threaded to the coarse adjustment rod 301. Rotating the fine adjustment rod 302 via the thread causes it to extend or retract relative to the coarse adjustment rod 301, further adjusting the length of the telescopic rod 3. The coarse adjustment rod 301 has a larger adjustment range, while the fine adjustment rod 302 has a smaller adjustment range. This two-stage adjustment structure allows for quick and accurate support of the telescopic rod 3 for the support plate 1.

[0040] In some embodiments, the single panel 2 includes a frame 25 and a panel 26 disposed on the frame 25. The single panel 2 uses the frame 25 and the panel 26 in a cooperative manner, with the frame 25 enhancing the load-bearing capacity of the single panel 2, while the panel 26 can reduce the amount of material used to reduce the weight of the single panel 2.

[0041] In some embodiments, the ends of the two sets of support plates 1 are provided with end plates 6. Specifically, the ends of the two sets of support plates 1 are provided with support grooves 201, through which crossbars 5 are mounted; the end plate 6 includes multiple independent plates, each of which is provided with a hanging groove 60, and the independent plate is mounted on the crossbar 5 through the hanging groove 60.

[0042] The end plate 6 forms a box-type support structure, which can prevent soil and gravel from falling from both ends of the trench and also prevent personnel from accidentally slipping. The end plate 6 uses multiple independent plates, which avoids the excessive volume and weight of a single plate 26, facilitates assembly by construction personnel, and reduces the need for heavy machinery. The crossbar 5 is erected on the support groove 201. The hanging groove 60 of the independent plate has an opening at the bottom. The crossbar 5 is inserted into the hanging groove 60 through this opening, thereby realizing the installation of the independent plate and facilitating disassembly.

[0043] In summary, the improved support structure uses multiple single-plate assembly to form the support plate, avoiding the existence of a single large-volume, heavy structure. This allows for manual operation by workers, reducing the need for heavy machinery, increasing construction convenience, and lowering costs. Furthermore, the use of pin-type structures during the assembly of components in the support structure enhances both structural stability and ease of assembly.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, this utility model can have various modifications, combinations, and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of the claims of this utility model.
