[0037] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0038] like Figures 1 to 5 As shown, the engineering foundation pit anti-collapse support structure provided in the present application includes a base 1 for support, a support plate 2 arranged on the base 1, and the support plate 2 is arranged around the inner side of the foundation pit 7.

[0039] Specifically, the base 1 includes a base body 11, one side of the base body 11 is open and adapted to fit with the support plate 2, and the other side is provided with a transverse plate 13, an adjustment groove 17 and a track 26 are respectively provided in the middle of the transverse plate 13 and the support plate 2, and an adjustment component 3 is provided between the track 26 and the adjustment groove 17 for supporting the support plate 2 and the transverse plate 13.

[0040] The outer sides of both ends of the support plate 2 are arranged in an arc shape and are provided with a slide groove 24 , at which an arc plate 4 is installed. The arc plate 4 and the support plate 2 form an enclosing area for protecting the surrounding frames of the foundation pit 7 .

[0041] The above-mentioned support structure design can provide higher stability through the combination of the base 1 and the support plate 2, especially at the corners of the foundation pit 7, reducing the risk of partial collapse caused by insufficient support.

[0042] It should be noted that the adjustment slots 17 and the tracks 26 set above can enable the position of the support plate 2 to be flexibly adjusted during the construction process, which is particularly useful for the complex and irregular shape of the foundation pit 7 and can effectively address the problem that the corners of the foundation border are not supported.

[0043] The enclosed area formed by the arc-shaped support plate 2 and the arc-shaped plate 4 can effectively wrap around the periphery of the foundation pit 7, prevent soil loss, and resist external impacts, further protecting the safety of the foundation pit 7.

[0044] Due to the convenience of the structural design during installation and adjustment, the operation time of construction workers can be reduced, the overall construction efficiency can be improved, and it helps to maintain the construction progress.

[0045] In some embodiments, two symmetrically arranged positioning holes 15 may also be provided at the top of the seat body 11 at the open-shaped part. A support shaft is inserted into the positioning holes 15, and the support shaft is inserted and adapted to the first chute 24 of the support plate 2.

[0046] At the same time, a baffle 12 is provided at the front end of the top of the seat body 11 at the open-shaped part. The baffle 12 is adapted to the bottom of the support plate 2 for strengthening the support plate 2; the seat body 11 is provided with sleeves 14 on both sides of the cross plate 13, and the inner side of the sleeves 14 is adapted to the adjusting assembly 3.

[0047] During the installation process, first place the seat body 11 at a suitable position inside the foundation pit 7, and then insert the support shaft into the positioning holes 15 to be adapted to the first chute 24 of the support plate 2 to ensure that the support plate 2 can be stably connected and avoid displacement and shaking;

[0048] At the same time, install the baffle 12 to enhance the fixity of the bottom of the support plate 2 to ensure that the support plate 2 is not easily deformed during the construction process. Moreover, the installation of the baffle 12 effectively reduces the displacement of the support plate 2 during the construction process and enhances the stability of the entire support structure. This reinforcement measure can significantly reduce the risk of collapse at the corners of the foundation pit 7.

[0049] The insertion setting of the support shaft and the chute of the support plate 2 ensures that the support plate 2 can be stably connected, improves the stability of the entire support system, and can better meet the needs of the irregular foundation pit 7.

[0050] Furthermore, connecting the adjusting assembly 3 to the cross plate 13 through the sleeves 14 can adjust the distance between the two support plates 2 as needed during the construction to better adapt to the actual situation of the foundation pit 7.

[0051] Through the cooperative design of the sleeves 14 and the adjusting assembly 3, the installation and adjustment processes are made more convenient, the operation is smoother, and it can quickly respond to the changing needs of the construction site.

[0052] It can be understood that, through the above-mentioned support structure, the bearing capacity of soil pressure can be enhanced, so that the stability of the foundation pit 7 during construction is better, and the safety hazards such as landslides caused by insufficient support are reduced.

[0053] In some other embodiments, a plug hole 16 may be opened on the outside of the sleeve 14, a reinforcement plate 6 is installed at the plug hole 16, a resistance block 5 is arranged on the top of the reinforcement plate 6, and the resistance block 5 and the reinforcement plate 6 are both arranged at a preset inclination angle.

[0054] In addition, the support plate 2 includes a plate body 22, and one side of the plate body 22 is provided with a resistance strip 21 arranged in a linear array for increasing the force-bearing area of the plate body 22, and the other side of the plate body 22 is provided with two symmetrically arranged mounting tubes 25 at the track 26, and the mounting tubes 25 are adapted to the adjustment component 3. A filling groove 23 is opened downward from the top of the plate body 22 for filling a buffer medium.

[0055] During the construction of the foundation pit 7, the sleeve 14 is first fixed at a preset position, and then the reinforcing plate 6 is connected to the sleeve 14 through the plug hole 16 to ensure that it is firm and not easy to loosen.

[0056] The inclined abutment block 5 of the reinforcement plate 6 contacts the support plate 2 to enhance the force-bearing effect and effectively disperse and resist external pressure during the construction process.

[0057] A resistance strip 21 is provided at the edge of the support plate 2 to increase the force-bearing area, and a buffer medium, such as gel, rubber filler, etc., is filled in the top of the support plate 2 to further enhance the impact resistance.

[0058] Installing the adjustment assembly 3 enables the support plates 2 to adjust their spacing according to the actual conditions of the construction site, ensuring that the support plates 2 can contact the inner wall of the foundation pit 7 and form a stable resistance effect, thereby improving the stability of the support.

[0059] See also Figure 1 The adjustment assembly 3 includes a reinforcement rod 31 and two sets of telescopic parts. One end of the reinforcement rod 31 is arranged at the abutment block 5, and the other end is arranged at the arc plate 4 through a slider 33.

[0060] The two groups of telescopic parts include a telescopic part 1 32 and a telescopic part 2 34 . The telescopic part 1 32 is arranged on the inner side of the sleeve 14 , and the telescopic part 2 34 is arranged on the inner side of the mounting tube 25 .

[0061] During the installation process, firstly, one end of the reinforcing rod 31 is fixed to the abutment block 5 to ensure that it can effectively connect the support plate 2 and the arc plate 4 to form a solid support system.

[0062] The first telescopic member 32 and the second telescopic member 34 are respectively installed inside the sleeve 14 and inside the mounting cylinder 25, and the two are used in cooperation to meet the need for adjusting the spacing of multiple support plates 2 in the foundation pit 7;

[0063] By adjusting the length of the telescopic member, the position and stress condition of the support plate 2 can be quickly changed to adapt to different situations of the foundation pit 7.

[0064] The adjusting assembly 3 can be adjusted as needed to maintain the best support effect and ensure the safety and efficiency of the construction of the foundation pit 7.

[0065] Through the design of the reinforcing rod 31 and the telescopic member, the entire support system can be flexibly adjusted, quickly adapt to the support and protection needs of the foundation pit 7, and thus provide a more reliable support effect.

[0066] The connection between the reinforcing rod 31 and the abutting block 5 effectively resists the deformation caused by soil thrust or construction vibration, significantly enhances the stability of the support structure, and reduces the risk of collapse; moreover, due to the simple installation and operation of the adjusting assembly 3, the construction personnel can quickly adjust the height and position of the support plate 2, reducing the construction time and improving the overall construction efficiency.

[0067] Please refer to Figure 1 、 Figure 9 ; The arc-shaped plate 4 includes an arc-shaped plate body 41, and convex strips 44 are arranged on both sides of the arc-shaped plate body 41, and the convex strips 44 are adapted to the first chutes 24 opened on both sides of the plate body 22 of the support plate 2.

[0068] One side of the arc-shaped plate body 41 is provided with an abutting soft block 42, and the abutting soft block 42 is used to increase the surface area outside the arc-shaped plate body 41 to improve the support effect. A second chute 43 is opened on the back of the arc-shaped plate body 41, and the second chute 43 is adapted to the slider 33 connected to the other end of the reinforcing rod 31.

[0069] It can be understood that the arc-shaped plate body 41 is designed to be arc-shaped, which can disperse the pressure exerted by the soil at the diagonal corners of the foundation pit 7. At the same time, convex strips 44 are arranged on both sides of the arc-shaped plate body 41, which can form a stable connection when contacting the plate body 22 of the support plate 2. The convex strips 44 are adapted to the first chutes 24 on both sides of the plate body 22 of the support plate 2 to ensure that the arc-shaped plate body 41 will not be unstable due to sliding when applying a load.

[0070] The abutting soft block 42 is located on one side of the arc-shaped plate body 41, and its function is to increase the surface area outside the arc-shaped plate body 41, improve the contact area with the surrounding soil or support structure, and enhance its support effect.

[0071] The soft block is usually made of an elastic material such as rubber, which can effectively buffer the pressure and impact force of the soil. When the applied load changes, the deformation ability of the abutting soft block 42 ensures the uniform distribution of force and prevents excessive local stress.

[0072] The second chute 43 is arranged on the back of the arc-shaped plate 41 and is adapted to the slider 33 connected to the other end of the reinforcing rod 31, allowing the slider 33 to move freely within the second chute 43, so that the connection between the reinforcing rod 31 and the arc-shaped plate 41 can be adjusted, thereby realizing the adjustment of the support plate 2 to meet the needs of the inner support of the foundation pit 7.

[0073] During the installation process, the arc-shaped plate 41 and the plate body 22 of the support plate 2 are connected through the convex strip 44 and the first chute 24, and then ensure that the contact soft block 42 is in full contact with the external environment.

[0074] By adjusting the connection between the reinforcing rod 31 and the slider 33, the construction personnel can realize the fine adjustment of the arc-shaped plate 41 to adapt to different construction environments and load requirements.

[0075] The elasticity of the contact soft block 42 enables the arc-shaped plate 41 to maintain stability when facing uneven loads, reducing the concentrated distribution of force, thereby effectively improving the support effect.

[0076] The convex strip 44 and the contact soft block 42 of the arc-shaped plate 41 can effectively increase the contact area with the soil or other structures, improve the bearing capacity of the entire support system, and thus reduce the support failure caused by uneven pressure.

[0077] It should be noted that the elastic characteristics of the contact soft block 42 enable the arc-shaped plate 41 to effectively absorb and disperse pressure when the load is applied, reduce the local stress concentration, extend the service life, keep the entire support system stable in various situations, enhance the safety during the construction process, and effectively reduce the occurrence probability of collapses or other accidents.

[0078] The above is only the embodiment of the present utility model and is not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications.
