[0002] Foundation pit support, as a key measure for underground structure construction and the safety of the surrounding environment of the foundation pit, aims to maintain the stability of the side walls of the foundation pit and its surrounding environment through support, reinforcement and protection measures. The currently widely used foundation pit support device mainly relies on the coordinated use of support plates and diagonal braces. The support plates are closely attached to the side walls of the foundation pit, and the diagonal braces are used to stabilize the support plates, so as to achieve the support effect on the side walls of the foundation pit and prevent the collapse of the foundation pit.

DETAILED DESCRIPTION

[0026] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the scheme of the utility model will be further described below. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] The foundation pit supporting device of the utility model embodiment is described below in conjunction with the accompanying drawings.

[0029] like Figure 1 and Figure 4 As shown, the foundation pit supporting device of the embodiment of the utility model may include two symmetrically arranged fixed plates 1, a translation mechanism 2, two symmetrically arranged rectangular frames 3 and two symmetrically arranged supporting mechanisms 4.

[0030] Wherein, the fixing plate 1 is detachably connected to the foundation pit.

[0031] It should be noted that one fixed plate 1 is arranged on one side of the foundation pit, and the other fixed plate 1 is arranged on the other side of the foundation pit, and the two fixed plates 1 are arranged opposite to each other, and the two fixed plates 1 together constitute a stable supporting structure, and the translation mechanism 2 spans the foundation pit.

[0032] The translation mechanism 2 includes two bearing seats 20, two guide plates 22 and a first screw 23, wherein the two bearing seats 20 are detachably connected to the corresponding fixed plates 1, the first screw 23 is rotatably connected to the two bearing seats 20, the two guide plates 22 are threadedly connected to the first screw 23, the two rectangular frames 3 are fixedly connected to the corresponding guide plates 22, and the two support mechanisms 4 are liftably and slidably connected to the corresponding rectangular frames 3, wherein the first screw 23 is used to synchronously drive the two guide plates 22 to move toward or away from each other.

[0033] Specifically, first, the relevant personnel can place the external support plate from the top of the foundation pit to the inside of the foundation pit by lifting or retrieving it, and fit it with the inner wall of the foundation pit, or they can make one end of the support plate penetrate into the soil by hammering. Then, the relevant personnel can rotate the first screw 23 by hand or with the help of external tools (such as pliers, wrenches, etc.). As the first screw 23 rotates, the two rectangular frames 3 can be synchronously driven through the guide plate 22 to drive the support mechanism 4 to move toward the support plate on the inner wall of the foundation pit, thereby supporting the support plate inside the foundation pit. Compared with the existing technology, the support operation can be completed without the construction personnel entering the foundation pit to install the diagonal bracing rods, thereby preventing the collapse of the foundation pit from causing personal injury to the construction personnel, improving the support efficiency of the foundation pit, and at the same time improving the safety of the workers during construction.

[0034] Furthermore, if Figure 1 As shown, the translation mechanism 2 further includes a first motor 21 , wherein the first motor 21 is disposed on a fixed plate 1 , and an output shaft of the first motor 21 is connected to one end of a first screw rod 23 .

[0035] It should be noted that the first motor 21 described in this embodiment is a forward and reverse motor with a self-locking function. By controlling the first motor 21 to rotate forward or reverse, the rotation direction of the first screw 23 can be changed, thereby adjusting the moving direction of the support mechanism 4. The self-locking function can be used to fix the angle of the first screw 23 after rotation, further improving the stability and reliability of the support mechanism 4 during support.

[0036] It can be understood that by controlling the first motor 21 to drive the first screw 23 to rotate, the cumbersome operation of traditional manual rotation is avoided, the work efficiency is greatly improved, and the entire support process is made more convenient and efficient.

[0037] In one embodiment of the present invention, Figure 1 As shown, the first screw rod 23 is a bidirectional screw rod, and the two guide plates 22 are respectively threadedly connected to the thread segments of the first screw rod 23 with opposite thread directions.

[0038] It should be noted that the bidirectional screw described in this embodiment is a screw having two thread segments with opposite thread directions, and is not described in detail here because it is a prior art.

[0039] Specifically, the first screw rod 23 is a bidirectional screw rod having two thread segments with opposite directions, so that the two guide plates 22 can be driven to move toward or away from each other synchronously, thereby changing the direction of the supporting mechanism 4 .

[0040] Furthermore, if Figure 3As shown, the foundation pit supporting device further includes a limiting mechanism 6 , which includes two fixed blocks 60 , a first sliding rod 61 and two sliding blocks 62 .

[0041] The two fixed blocks 60 are fixed on the corresponding fixed plates 1 respectively, the first sliding rod 61 is fixed between the two fixed blocks 60, the two sliding blocks 62 are slidably connected to the first sliding rod 61 respectively, and the two sliding blocks 62 are fixedly connected to the corresponding rectangular frames 3 respectively.

[0042] It can be understood that when the rectangular frame 3 moves, the slider 62 is also driven to move on the first slider 61. By setting the slider 62 to cooperate with the first slider 61, the rectangular frame 3 can be limited, thereby improving the stability of the rectangular frame 3 when moving.

[0043] Furthermore, if Figure 3 As shown, the slider 62 is symmetrically distributed with the guide plate 22 corresponding to the same rectangular frame 3 .

[0044] It can be understood that, due to the symmetrical layout of the slider 62 and the guide plate 22, the rectangular frame 3 can be evenly stressed, which not only improves the structural stability of the rectangular frame 3, but also ensures the stability and reliability of the rectangular frame 3 during movement.

[0045] In one embodiment of the present invention, Figure 1 As shown, the supporting mechanism 4 includes a mounting plate 40 and an abutting plate 41 .

[0046] One end of the mounting plate 40 is connected in the rectangular frame 3 in a liftable and slidable manner, and the other end of the mounting plate 40 is fixedly connected to the abutting plate 41 , and the mounting plate 40 is L-shaped.

[0047] Specifically, during the movement of the rectangular frame 3 , it can drive the mounting plate 40 to push the abutting plate 41 against the side wall of the supporting plate in the foundation pit.

[0048] In order to further clarify the above embodiment, in one embodiment of the present application, Figure 1 As shown, the abutment plate 41 includes a cross bar (not marked in the figure), a plurality of inclined bars (not marked in the figure) and a plurality of vertical bars (not marked in the figure), wherein the cross bar is fixedly connected to the abutment plate 41, one end of the plurality of inclined bars is fixedly connected to the cross bar, the other ends of the plurality of inclined bars are respectively fixedly connected to the corresponding vertical bars, and the plurality of inclined bars are arranged side by side and equidistantly.

[0049] Among them, it can be understood that by setting a plurality of inclined rods in conjunction with vertical rods, multi-point support can be formed for the support plate in the foundation pit, thereby improving the stability of the support plate when supporting, and the design of the vertical rods can increase the contact area with the support plate, further enhancing the stability of the support plate when subjected to force, and this structure also ensures the reliability of the abutment plate 41.

[0050] As a possible situation, reinforcing ribs may be added to the diagonal rod and the mounting plate 40 to further enhance the supporting stability of the diagonal rod.

[0051] Furthermore, if Figure 2 As shown, the foundation pit supporting device further includes two symmetrically arranged lifting mechanisms 5 , and the lifting mechanisms 5 include a second motor 50 and a second screw 51 .

[0052] Among them, the second motor 50 is arranged on the rectangular frame 3, and the output shaft of the second motor 50 passes through the upper surface of the rectangular frame 3 and is fixedly connected to the second screw 51, the end of the second screw 51 away from the second motor 50 is rotatably connected to the inner bottom wall of the rectangular frame 3, and the second screw 51 is threadedly connected to the threaded hole opened on the mounting plate 40.

[0053] Specifically, relevant personnel control the second motor 50, and the output shaft of the second motor 50 rotates to drive the mounting plate 40 to move up and down, so that the mounting plate 40 moves toward the depth of the foundation pit. At the same time, by adjusting the height of the mounting plate 40, the supporting point of the abutment plate 41 on the support plate in different foundation pits can be changed to find a suitable supporting position (for example, the middle position of the support plate) to enhance the supporting stability of the support plate and ensure the safety of the construction.

[0054] Furthermore, if Figure 2 As shown, the foundation pit supporting device further includes two symmetrically arranged second sliding bars 7 , the two second sliding bars 7 are respectively fixed inside the rectangular frame 3 , and the fixing plate 1 is slidably connected to the two second sliding bars 7 .

[0055] It can be understood that the second slide bar 7 can limit the mounting plate 40, thereby ensuring the stability of the mounting plate 40 when it moves up and down.

[0056] In one embodiment of the present invention, Figure 1 As shown, a plurality of through holes 10 are formed on the fixing plate 1 , and a matching rivet 8 can be inserted into each through hole 10 .

[0057] It is understandable that the relevant personnel insert the rivet 8 into the through hole 10 and extend it to the inside of the ground, so as to ensure that the fixing plate 1 can be firmly fixed on the foundation pit. This fixing method not only effectively prevents the movement of the fixing plate 1 when supporting the foundation pit, but also improves the stability of the foundation pit supporting device during support.

[0058] In summary, the foundation pit support device of the embodiment of the utility model can complete the support operation without the construction workers entering the foundation pit to install the support, thereby preventing the collapse of the foundation pit from causing personal injury to the construction workers, improving the support efficiency of the foundation pit, and also improving the safety of the workers during construction.
