[0002] During the foundation pit excavation process, the stability of the side soil mass is a key factor to ensure the construction safety and smooth progress. If the side support is improper, it may lead to serious consequences such as soil mass slippage and collapse, affecting the project progress and personnel safety. Traditional foundation pit support methods mostly rely on materials such as wooden boards, steel pipes or concrete for temporary support. These methods often have problems such as inconvenient installation and disassembly, poor adaptability, insufficient stability and resource waste. Especially when facing foundation pits with different widths, lengths and depths, traditional support methods are difficult to meet the flexible adjustment requirements. In view of the above problems, the inventor designed an assemblable sliding rail type support box. Content of the Utility Model

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0034] To achieve the above invention object, as Figures 1-5 shown, the present invention provides a sliding rail type support box, including a column 3. Side sliding rails 4 are arranged on both sides of the column 3. The inner sides of two corresponding columns 3 are supported by an inner support 7. The support plate I 9 and the support plate II 11 are slidably inserted into the side sliding rails 4 of adjacent two columns 3. The support plate I 9 is slidably inserted at the bottommost position. The number of the support plate II 11 is adjusted according to the actual depth of the foundation pit, so as to be able to adapt to the support of the side of the foundation pit with different depths;

[0035] In this embodiment, when excavating a foundation pit, it is necessary to support the side of the foundation pit. Otherwise, the soil on the side of the foundation pit will slide off. At this time, a slide rail type support box is needed. First, insert the columns 3 at equal intervals into the side position of the foundation pit, and then support between the inner sides of the two columns 3 through the inner support 7. Then, first slide the support plate I 9 into the inner side slide rail 4 of the adjacent column 3. This is pressed downward by auxiliary tools such as an excavator, so that the support plate I 9 slides to the bottommost position of the foundation pit. Then, the support plate II 11 is successively slid by auxiliary tools such as an excavator from the upper side, so that the uppermost support plate II 11 reaches the top of the foundation pit, thus completing the excavation support of the foundation pit, avoiding the sliding of the soil on the side of the foundation pit. Moreover, through this kind of assembled design, it can adapt to the foundation pit supports of different widths, lengths, and depths, making the support use of the slide rail type support box more diverse. And compared with the existing temporary wooden support, the slide rail type support box in this technical document is more stable, and can be adjusted according to actual use requirements. The slide rail type support box is made of steel structure and can be recycled, saving resources to a certain extent and avoiding waste of resources.

[0036] As Figure 4 shown, the inner support 7 is assembled through the connecting flange 6, so that the length of the inner support 7 can be adjusted. Both ends of the inner support 7 are connected with support bases 5. An L-shaped clamping block 12 is integrally formed on the outer side of the support base 5. The support base 5 is slidably clamped on the column 3 through the L-shaped clamping block 12. In this way, the up and down movement of the support base 5 can be realized through the L-shaped clamping block 12, so that the inner support 7 can stably support the inner side of the column 3 at a suitable position through the support base 5.

[0037] Preferably, a rolling bearing 13 is arranged inside the support base 5. The rolling bearing 13 is rotationally connected with the support base 5 through a rotating shaft, and the rolling bearing 13 on the support base 5 contacts the inner wall of the column 3. In this way, through the design of the rolling bearing 13, the friction between the support base 5 and the column 3 can be reduced, so that the up and down movement of the support bases 5 at both ends of the inner support 7 is smoother, and thus the position adjustment of the inner side support of the column 3 can be better realized.

[0038] Optionally, an inner support lifting hole 8 for hoisting and moving is arranged on the side of the inner support 7. Through the inner support lifting hole 8, the inner support 7 can be hoisted by means of auxiliary tools such as an excavator, making it more convenient to carry and move the inner support 7.

[0039] As Figure 1 、 5As shown in the figure, a plurality of insertion slots 10 are provided at the top end of the support plate I 9. The upper and lower ends of the support plate II 11 are respectively provided with a support plate lifting hole 2 and a clamping U-shaped hole 1. The support plate I 9 and the support plate II 11 are connected through the insertion slot 10 and the clamping U-shaped hole 1. Adjacent two support plates I 9 are connected through the support plate lifting hole 2 and the clamping U-shaped hole 1. After the connection is completed, bolts can be inserted into the corresponding apertures to achieve fixation, so as to realize the fixation of adjacent support plates I 9 and support plates II 11, so that the slide rail type support box formed by the support plates I 9 and support plates II 11 becomes a whole, avoiding gaps between adjacent ones, and even avoiding the slippage of the foundation pit soil to a certain extent, so that the slide rail type support box can more stably realize the foundation pit support function.

[0040] Optionally, the bottom end of the support plate I 9 is designed with an inclined mouth, which is in the shape of a blade. In this way, when the support plate I 9 is pressed downward, the inclined mouth in the shape of a blade will cut the redundant soil on the side of the foundation pit, so that the support plate I 9 can be pressed downward more smoothly, and it also clears the obstacles for the insertion of the support plate II 11.

[0041] Working principle:

[0042] 1. First, insert the column 3 into the side of the foundation pit, and then connect two columns 3 through the internal support 7 to form a preliminary support framework.

[0043] 2. Slide the support plate I 9 into the side slide rail 4 of the column, and press it to the bottom of the foundation pit through mechanical equipment.

[0044] 3. According to the depth of the foundation pit, slide the support plate II 11 one by one until the top to complete the support of the entire foundation pit.

[0045] 4. The internal support 7 adjusts the length through the connection flange 6, and slides on the column 3 through the support base 5. The L-shaped block 12 of the support base 5 enables it to move up and down to adapt to the support requirements of different depths.

[0046] The above is only the preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
