For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be an internal connection between two elements or an interaction relationship between two elements; for ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to the specific circumstances.

[0031] like Figures 1 to 5 As shown, the present disclosure provides a foundation pit support module 1 , which includes an adjuster 2 , a supporting connection structure 3 and two support plates 4 .

[0032] The regulator 2 is used to be fixed inside the foundation pit, and two supporting plates 4 are arranged relatively on both sides of the regulator 2 in a first direction (such as the width direction of the foundation pit), and the supporting plates 4 are used to abut against the side walls of the foundation pit, and the supporting connection structure 3 is connected between the regulator 2 and the supporting plates 4;

[0033] The regulator 2 has a first plug-in portion 21 and a second plug-in portion 22 at opposite ends, respectively. The shapes and sizes of the first plug-in portion 21 and the second plug-in portion 22 are adapted so that the first plug-in portion 21 is suitable for plugging and matching with the second plug-in portion 22 of the regulator 2 in another foundation pit support module 1. The support plate 4 has a third plug-in portion 41 and a fourth plug-in portion 42 at opposite ends, respectively. The shapes and sizes of the third plug-in portion 41 and the fourth plug-in portion 42 are adapted so that the third plug-in portion 41 is suitable for plugging and matching with the fourth plug-in portion 42 of the support plate 4 in another foundation pit support module 1.

[0034] The working process of the above-mentioned foundation pit support module 1 is as follows: when it is necessary to support the foundation pit, the regulator 2 of the foundation pit support module 1 can be fixed in the foundation pit, the support plate 4 is pressed against the side wall of the foundation pit, and the supporting connection structure 3 is installed between the regulator 2 and the support plate 4. The support can be completed by the support plate 4 supporting the force of the side wall of the foundation pit. In some specific construction scenarios, such as subway construction, continuous excavation along the length direction of the foundation pit is required. In this case, a single foundation pit support module 1 is first installed, and the connection direction of the first plug-in portion 21 and the second plug-in portion 22 of the regulator 2 is adjusted to be the same as the length direction of the foundation pit. The first plug-in portion 21 of the regulator 2 and the second plug-in portion 22 of another regulator 2 are plugged in and matched, and at the same time, the third plug-in portion 41 of the support plate 4 connected to the regulator 2 and the fourth plug-in portion 42 of another support plate 4 are plugged in and matched, so that multiple foundation pit support modules 1 can be spliced ​​and supported in the length direction of the foundation pit. When it is necessary to support foundation pits at different heights, the adjuster 2 is plugged into the second plugging portion 22 of another adjuster 2 through the first plugging portion 21 in the height direction. Figure 5 As shown, a plurality of foundation pit supporting modules 1 are stacked in the height direction of the foundation pit, and splicing support of the plurality of foundation pit supporting modules 1 can be achieved in the height direction of the foundation pit.

[0035] Through the above technical scheme, the regulator 2 is connected to the support plate 4 through the supporting connection structure 3, and the support plate 4 offsets the force from the side wall of the foundation pit to achieve support for the foundation pit. Since the first plug-in portion 21 and the second plug-in portion 22 with matching shapes and sizes are provided at the opposite ends of the regulator 2, and the third plug-in portion 41 and the fourth plug-in portion 42 with matching shapes and sizes are provided at the opposite ends of the support plate 4, the first plug-in portion 21 and the second plug-in portion 22 of adjacent regulators 2 are plug-fitted, and the third plug-in portion 41 and the fourth plug-in portion 42 of adjacent support plates 4 are plug-fitted, and multiple foundation pit support modules 1 can achieve splicing support. By splicing multiple foundation pit support modules 1, splicing support in a certain direction of the foundation pit (such as the length direction or height direction of the foundation pit) is achieved, so that the foundation pit support device 100 is suitable for foundation pits with different construction requirements.

[0036] In addition, since a plurality of foundation pit support modules 1 can be spliced ​​together by plugging and fitting, the operation is simple, and the foundation pit can be supported while the foundation pit is being excavated, which greatly improves the support efficiency of the foundation pit.

[0037] See also Figures 1 to 3 Optionally, the regulator 2 has a first end face and a second end face in the second direction; the first plug-in portion 21 includes a first protrusion 211 located on the first end face, and the second plug-in portion 22 includes a first groove 221 located on the second end face, and the second direction is perpendicular to the first direction; the support plate 4 has a third end face and a fourth end face in the second direction; the third plug-in portion 41 is configured to be a second protrusion 411 located on the third end face, and the fourth plug-in portion 42 is configured to be a second groove 421 located on the fourth end face.

[0038] In this embodiment, the first protrusion 211 of the first plug-in portion 21 of the adjuster 2 is inserted into the first groove 221 of the second plug-in portion 22 of the other adjuster 2, and the splicing of the two adjusters 2 is achieved through the plug-in fit between the first protrusion 211 and the first groove 221. The second protrusion 411 of the third plug-in portion 41 of the support plate 4 is inserted into the second groove 421 of the fourth plug-in portion 42 of the other support plate 4, and the splicing of the two support plates 4 is achieved through the plug-in fit between the second protrusion 411 and the second groove 421.

[0039] The second direction may be the length direction or the height direction of the foundation pit. Figure 1 In the embodiment shown, the second direction is the length direction of the foundation pit. In this way, during the excavation of the foundation pit along the height direction, excavation and support can be carried out simultaneously, which ensures support efficiency and improves safety.

[0040] The present disclosure does not limit the structure of the first protrusion 211 and the second protrusion 411. In order to improve the stability of the connection, optionally, the first protrusion 211 and the second protrusion 411 are both constructed as T-shaped protrusions, and the T-shaped protrusions include a connecting section and an inserting section. The connecting section extends along the second direction, and the inserting section on the first protrusion 211 is used to be plugged and matched with the first groove 221 of the regulator 2 of another foundation pit support module 1, and the inserting section on the second protrusion 411 is used to be plugged and matched with the second groove of the regulator 2 of another foundation pit support module 1.

[0041] By plugging the plug-in section of the T-shaped protrusion into the first groove 221 or the second groove 421, the connecting section of the T-shaped protrusion connects and limits the first protrusion 211 and the first groove 221, or connects and limits the second protrusion 411 and the second groove 421, which is convenient for plug-in and not easy to be accidentally separated, thereby ensuring a stable connection between adjacent regulators 2 or adjacent support plates 4.

[0042] It can be understood that in other embodiments, the first protrusion 211, the second protrusion 411 and the first groove 221, the second groove 421 can be constructed into other plug-in fit shapes such as L-shape, so that the first protrusion 211 and the first groove 221 can be plug-fitted, and the second protrusion 411 and the second groove 421 can be plug-fitted.

[0043] To ensure that the foundation pit support module 1 is suitable for foundation pits of different depths, please refer to Figure 1 and Figure 2 , the regulator 2 is in the third direction (such as Figure 1 It has a fifth end face and a sixth end face in the up and down direction of the figure shown, that is, the height direction of the foundation pit; the first plug-in portion 21 includes a plug-in rod 212 located at the fifth end face, and the second plug-in portion 22 includes a plug-in hole 222 located at the sixth end face, and the third direction is perpendicular to the first direction; the fifth end face is located below the sixth end face.

[0044] During the specific implementation process, the plug-in rod 212 of the regulator 2 located on the fifth end face is plugged and fixed on the bottom of the foundation pit, and the plug-in rod 212 of another regulator 2 is inserted from the plug-in hole 222 on the sixth end face, so that multiple regulators 2 are spliced ​​and extended along the third direction, and multiple foundation pit support modules 1 are spliced ​​in the third direction. In this way, multiple foundation pit support modules 1 support foundation pits of different depths.

[0045] See also Figure 1 , Figure 3 and Figure 4In order to ensure a stable connection between the adjuster 2 and the support plate 4, optionally, in one embodiment of the present disclosure, the support connection structure 3 includes at least one connection component, each connection component includes a support rod 31 and a connection plate 32, the connection plate 32 is connected to the adjuster 2, and a first connection support 43 is provided on the end surface of the support plate 4 facing the adjuster 2, and a second connection support 321 is provided on the end surface of the connection plate 32 facing the support plate 4, one end of the support rod 31 is hinged to the first connection support 43, and the other end of the support rod 31 is hinged to the second connection support 321.

[0046] During the support process, the adjuster 2 is fixed inside the foundation pit, and the supporting connection structure 3 includes a connection assembly. The first connection support 43 of the support plate 4 and the second connection support 321 of the connection plate 32 are relatively arranged. The support rod 31 in the connection assembly is hinged and fixed between the first connection support 43 and the second connection support 321. The support rod 31 provides supporting force for the connection plate 32 that is against the side wall of the foundation pit to ensure stable support.

[0047] It can be understood that since the support rod 31 is hinged between the support plate 4 and the connecting plate 32, and the connecting plate 32 is connected to the adjuster 2, the support rod 31 can rotate around the second connecting support 321 on the connecting plate 32, driving the position of the support plate 4 to change. In this way, the application scope of the foundation pit support module 1 can be improved, and support can be provided for different positions of the side wall of the foundation pit. When facing foundation pits with different inclinations, the rotation angle of the support rod 31 can be adjusted to make the support plate 4 abut against the side wall of the foundation pit with different inclinations, thereby effectively improving the application scope of the foundation pit support module 1 for foundation pits with different inclinations.

[0048] Optionally, in the present disclosure, the foundation pit support module 1 may further include a locking mechanism (not shown), which is used to unlockably lock the support rod 31 on the support plate 4 (such as locking it on the first connecting support 43). In this way, when the support rod 31 rotates to the corresponding supporting position, the support rod 31 can be locked by the locking mechanism. Here, the locking mechanism may include but is not limited to a locking pin, which may be inserted and removed through the first connecting support 43 and the support rod 31.

[0049] See also Figures 1 to 4 The connecting plate 32 is detachably connected to the regulator 2. When the foundation pit support module 1 needs to be assembled or disassembled, quick disassembly and assembly can be achieved through the detachable connecting plate, and the present disclosure does not limit this. Optionally, in one embodiment of the present disclosure, the regulator 2 is provided with a first screw hole 23, the connecting plate 32 is provided with a second screw hole 322, and the foundation pit support module 1 further includes a threaded fastener 5, and the threaded fastener 5 is connected to the first screw hole 23 and the second screw hole 322 to thread the connecting plate 32 to the regulator 2.

[0050] During the support process, the threaded fastener 5 threads the connecting plate 32 onto the adjuster 2 through the first screw hole 23 on the adjuster 2 and the second screw hole 322 on the connecting plate 32. In this way, the connecting plate 32 and the adjuster 2 can be detachably connected while ensuring the stability of the connection.

[0051] Optionally, there are multiple first screw holes 23 , and the multiple first screw holes 23 have screw hole rows that are spaced apart in the up-and-down direction. The threaded fastener 5 is suitable for being threadedly connected with the first screw holes 23 at different positions on the screw hole rows.

[0052] It can be understood that the number of the first screw holes 23 is set according to specific construction requirements. Among the multiple first screw holes 23, there are rows of screw holes arranged at intervals along the up and down directions. The threaded fasteners 5 are threadedly connected to the first screw holes 23 at different positions. The connecting plate 32 can change its position in the up and down directions of the adjuster 2, driving the support plate 4 to change its position relative to the up and down directions of the adjuster 2, thereby adapting to foundation pits of different heights.

[0053] Optionally, a rack structure 24 extending in the up-down direction is provided on the end surface of the regulator 2 facing the connecting plate 32 , and an engaging portion 323 is provided on the surface of the connecting plate 32 facing the regulator 2 , and the engaging portion 323 is used to engage with the rack structure 24 .

[0054] It is understandable that since the force exerted by the side walls of the foundation pit on the foundation pit support module 1 is not uniform, some side walls of the foundation pit need to be supported intensively. By providing a meshing rack structure 24 and a meshing portion 323 on the adjuster 2 and the connecting plate 32, the connection stability between the connecting plate 32 and the adjuster 2 can be effectively improved, thereby indirectly improving the stability of the overall structure of the foundation pit support module 1.

[0055] According to another aspect of the present disclosure, a foundation pit supporting device 100 is provided, comprising a plurality of the above-mentioned foundation pit supporting modules 1, wherein the plurality of foundation pit supporting modules 1 are suitable for being spliced ​​along the length direction and / or height direction of the foundation pit.

[0056] When the foundation pit extends along the length direction, a plurality of foundation pit support modules 1 are synchronously spliced ​​and supported along the length direction of the foundation pit.

[0057] When the foundation pit extends in the height direction, multiple foundation pit support modules 1 are synchronously spliced ​​and supported in the height direction of the foundation pit. Figure 5 shown.

[0058] When the foundation pit extends in both the length direction and the height direction, a plurality of foundation pit support modules 1 are synchronously spliced ​​and supported along the length direction and the height direction of the foundation pit.

[0059] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, the technical solution of the present disclosure can be subjected to a variety of simple modifications, and these simple modifications all fall within the protection scope of the present disclosure.

[0060] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction.
