Suspended two-way building foundation pit supporting device and method

[0051] Example 1, please refer to Figure 1-7 , a suspended two-way building foundation pit support device, comprising:

[0052] Two side support plates 1 are provided and are correspondingly arranged on both sides of the interior of the foundation pit, and the opposite sides of the two side support plates 1 are respectively provided with supporting force dispersion components 2;

[0053] The supporting force dispersing assembly 2 includes a supporting frame 21, a longitudinal splitting rod 22 and a horizontal splitting rod 23. The opposite side edges of the two side support plates 1 are respectively provided with a supporting frame 21, and the supporting frame 21 is provided with two criss-crossing longitudinal The sub-rod 22 and the horizontal sub-rod 23 , and the side surfaces of the sub-rod 22 and the horizontal sub-rod 23 are respectively connected to the side surfaces of the side support plate 1 . The support frame 21 and the vertical and horizontal cross-shaped vertica...

[0073] Example 2, please refer to figure 1 with 7 , a suspended two-way building foundation pit support device, the structure of this embodiment is roughly the same as that of Embodiment 1, the difference is that:

[0074]Also includes a side wall waterproof erosion unit 6, the side wall waterproof erosion unit 6 includes a water guide assembly, a flow blocking assembly and a water collection assembly, the side support plate 1 is provided with a flow blocking assembly near the side wall of the foundation pit, and the side support The top of the plate 1 is provided with a water guide assembly, and the inside of the side support plate 1 is provided with a water collection assembly.

[0075] The water guiding component can guide the water on the top edge of the foundation pit and flow into the blocking component. The blocking component can prevent the large-scale flow of water in the gap between the side support plate 1 and the side wall of the foundation pit. The water compone...

[0079] Embodiment three, please refer to figure 1 with 3 , a suspended two-way building foundation pit support device, the structure of this embodiment is roughly the same as that of Embodiment 2, the difference is that:

[0080] It also includes an anti-sliding assembly 7, the bottom of the supporting force dispersion assembly 2 is installed with an anti-sliding assembly 7 for placing the side support plate 1 to slide downward. The anti-sliding component 7 can raise the side support plate 1 at the initial stage of the support of the side support plate 1, so that the side support plate 1 can be supported to a predetermined position, so as to avoid that the front side support plate 1 is not supported tightly along the side of the foundation pit. The wall slides down.

[0081] Anti-sliding assembly 7 comprises sliding sleeve 71, fixed block 72, embedded nut 73, adjusting screw rod 74, torsion block 75, bearing 76, brace plate 77, retaining plate 78, and the two ends sides of s...
