[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0021] The deep foundation pit supporting device of the utility model embodiment is described below with reference to the accompanying drawings.

[0022] like Figure 1-Figure 3 As shown, the deep foundation pit supporting device of the embodiment of the utility model may include a foundation supporting pile 1, a transverse fixing pile 2 and an anti-tilt component 3.

[0023] Wherein, a ground anchor 10 is arranged at the bottom of the foundation support pile 1 .

[0024] It can be understood that, by providing the ground anchor 10, additional support and stability can be provided to the support device, preventing it from moving, tilting or collapsing due to external forces, thereby improving the stability of the support device.

[0025] The transverse fixing pile 2 passes through the foundation supporting pile 1 and is fixed to the soil. A fixing block 20 is provided at one end of the transverse fixing pile 2 and is connected to the foundation supporting pile 1 . A ground anchor 10 is provided at the other end of the transverse fixing pile 2 .

[0026] It should be noted that one end of the transverse fixing pile 2 described in this embodiment is fixedly arranged outside the foundation support pile 1, and the other end of the transverse fixing pile 2 is arranged in the soil, so as to improve the fixing effect of the foundation support pile 1.

[0027] The anti-tilt assembly 3 may include an abutment support pile 30 , a first connection mechanism 31 and a second connection mechanism 32 .

[0028] Among them, the abutment support pile 30 is arranged on one side of the foundation support pile 1, one end of the first connection mechanism 31 is rotatably connected to the top of the foundation support pile 1, the other end of the first connection mechanism 31 is rotatably connected to the top of the abutment support pile 30, one end of the second connection mechanism 32 is abutted against the bottom of the foundation support pile 1, and the other end of the second connection mechanism 32 is abutted against the bottom of the abutment support pile 30.

[0029] It should be noted that the bottom of the abutment support pile 30 described in this embodiment is also provided with a ground anchor 10 , so as to ensure the fixed support effect of the abutment support pile 30 .

[0030] It should be noted that the first connection mechanism 31 described in this embodiment abuts against the top of the foundation support pile 1 and the abutment support pile 30 respectively, so that the abutment support pile 30 supports the foundation support pile 1, further preventing the deep foundation pit from tilting.

[0031] It can be understood that, by providing the second connection mechanism 32 , the supporting effect of the abutment support pile 30 on the foundation support pile 1 can be further enhanced.

[0032] Specifically, in the actual operation process, relevant personnel cast multiple foundation support piles 1 in sequence on the outside of the deep foundation pit to achieve the support of the deep foundation pit, and pass the transverse fixing piles 2 through the foundation support piles 1 for transverse fixing, so as to further enhance the supporting effect of the foundation support piles 1 on the deep foundation pit and prevent the deep foundation pit support from tilting. Then, an abutting support pile 30 is installed on one side of the foundation support pile 1, and the first connecting mechanism 31 is rotated and connected to the foundation support pile 1 and the abutting support pile 30 respectively, and the second connecting mechanism 32 is abutted with the foundation support pile 1 and the abutting support pile 30 respectively. Therefore, when the deep foundation pit is tilted, the abutting support pile 30 abuts against the first connecting member and the second connecting member to support the foundation support pile 1, thereby further preventing the deep foundation pit support from tilting, and greatly enhancing the supporting effect of the foundation support pile 1 on the deep foundation pit.

[0033] In one embodiment of the present invention, Figure 1-Figure 3 As shown, the first connection mechanism 31 may include a connection block 310 and a connection rod 311 .

[0034] The connection blocks 310 are respectively arranged on the top of the foundation support pile 1 and the transverse fixed pile 2, and the connection rods 311 are rotatably connected to the connection blocks 310 respectively.

[0035] It should be noted that the connecting rods 311 described in this embodiment are respectively abutted against the connecting blocks 310 , so that the abutting supporting piles 30 abut and support the foundation supporting piles 1 through the connecting rods 311 , thereby ensuring the supporting effect of the abutting supporting piles 30 .

[0036] In one embodiment of the present invention, Figure 1-Figure 3 As shown, the second connection mechanism 32 may include an inserting cylinder 320 , two abutting blocks 321 and an inserting block 322 .

[0037] The plug-in tube 320 is disposed between the foundation support pile 1 and the abutment support pile 30 , two abutment blocks 321 are respectively slidably disposed at the bottom of the plug-in tube 320 , and the plug-in blocks 322 are respectively slidably abutted against the abutment blocks 321 .

[0038] It should be noted that the top of one side of the plug-in tube 320 described in this embodiment is beveled, and the bevel corresponds to the spiked portion at the bottom of the plug-in block 322, thereby facilitating the sliding connection between the plug-in block 322 and the abutment block 321, and realizing the translational sliding of the plug-in block 322 out of the plug-in tube 320, and respectively abutting and supporting the abutment support pile 30 and the foundation support pile 1.

[0039] In one embodiment of the present invention, Figure 1-Figure 3 As shown, a plug-in limiting member 3200 is provided on the sliding sleeve of the plug-in tube 320 .

[0040] It should be noted that the plug-in limit member 3200 described in this embodiment is sleeved on the outside of the plug-in tube 320. The setting of the plug-in limit member 3200 facilitates the vertical insertion of the plug-in tube 320 and avoids oblique insertion, which affects the abutment and support effect between the abutment block 321 and the abutment support pile 30 and the foundation support pile 1.

[0041] In one embodiment of the present invention, Figure 1-Figure 3 As shown, a limiting cover 3220 is slidably sleeved on the plug-in block 322 .

[0042] It should be noted that the limit cover 3220 described in this embodiment is sleeved on the outside of the plug-in block 322. The setting of the limit cover 3220 facilitates the vertical insertion of the plug-in block 322 and avoids oblique insertion, which affects the abutment and support effect between the abutment block 321 and the abutment support pile 30 and the foundation support pile 1.

[0043] In one embodiment of the present invention, Figure 1-Figure 3 As shown, the plug-in block 322 is hollow, and one end of the plug-in block 322 that abuts against the supporting pile 30 and the foundation supporting pile 1 is open.

[0044] It should be noted that the abutment support column described in this embodiment is installed after distance measurement, so that the insertion tube 320 is inserted into the center position of the foundation support pile 1 and the abutment support pile 30. After the insertion block 322 is inserted into the abutment block 321, the abutment block 321 can abut against the foundation support pile 1 and the abutment support pile 30.

[0045] It is understandable that the hollow setting of the abutment block 321 can squeeze the soil in the moving process into the abutment block 321, making it convenient for the plug-in block 322 to abut against the abutment block 321 in the soil, thereby avoiding the situation where the soil is difficult to compress and squeeze out and cannot abut against the abutment block 321.

[0046] Specifically, in the actual operation process, the relevant personnel cast multiple foundation support piles 1 in sequence on the outside of the deep foundation pit to achieve the support of the deep foundation pit, and pass the transverse fixing piles 2 through the foundation support piles 1 for transverse fixing, so as to further improve the support effect of the foundation support piles 1 on the deep foundation pit and prevent the deep foundation pit support from tilting. Then, the abutment support pile 30 is installed on one side of the foundation support pile 1, and the two ends of the connecting rod 311 are respectively rotated and connected to the foundation support pile 1 and the abutment support pile 30. On the pile 30, the plug-in tube 320 is installed, and the plug-in block 322 is slidably plugged with the abutment block 321 in the plug-in tube 320, so that the abutment block 321 moves toward the foundation support pile 1 and the abutment support pile 30 and abuts against it. When the deep foundation pit is tilted, the abutment support pile 30 supports the foundation support pile 1 through the abutment of the connecting rod 311 and the abutment block 321, thereby further preventing the deep foundation pit support from tilting and greatly improving the support effect of the foundation support pile 1 on the deep foundation pit.

[0047] In summary, the embodiments of the utility model can further improve the support stability of the deep foundation pit, prevent the deep foundation pit from tilting, and thus ensure the progress of the construction project.
